Description

Resource management method and device

The present invention relates to the field of communications, and in particular, to a resource management method and apparatus.

Background technique

GSM (Global System for Mobile Communications) is a mobile communication technology standard originated in Europe and is the second generation mobile communication technology. In the GSM system, the frequency resources used by each operator are specified by the GSM protocol, so the frequency resources are very limited for each operator. In the existing GSM system, one base station controller controls a group of base stations, and each base station may have multiple physical cells, and each physical cell includes one or more physical carriers. The configuration of the parameters of different physical cells in the same base station may be different, which occupies a lot of valuable frequency resources. The parameters are carrier number, frequency point, channel configuration, etc., and the frequency point is given fixed. Frequency or frequency hopping group.

For example, in the GSM900 system, when the user equipment sends information to the base station, the uplink frequency band is occupied, and the working frequency of the uplink frequency band is 890 to 915 MHz. When the base station sends information to the user equipment, the downlink frequency band is occupied. The operating frequency of the frequency band is 935~960 MHz, and the frequency interval is 200KHz. According to the frequency interval, the uplink frequency band can be equally divided into 125 radio frequency segments from 890MHz to 915MHz, and the starting frequency of each frequency band is numbered. Obtaining 1 to 125 consecutive numbers of the uplink frequency band, for example, the starting frequency of the frequency band 890 MHz to 890.2 MHz is 890 MHz; correspondingly, the downlink frequency band is equally divided into 125 wireless frequency segments from 935 MHz to 960 MHz. , numbering the starting frequency of each frequency band to obtain 1 to 125 consecutive numbers of the downlink frequency band; these numbers for the fixed frequency are the frequency points, such as the uplink frequency corresponding to the frequency of 890 MHz in the uplink frequency band. The frequency of the channel band is 1. In the GSM network, frequency points can be used to indicate the transmission frequencies of the base station and the user equipment. For example, if the frequency of the specified carrier is 3, the frequency occupied by the user equipment in the uplink frequency band is 890.4 MHz when the user equipment sends the information to the base station, and the frequency occupied by the downlink frequency band is 935.4 MHz when the base station sends the information to the user equipment. . Each carrier uses a given fixed frequency point or uses one frequency hopping group according to the configuration to perform uplink and downlink transmission and reception. When using a frequency hopping group, The wave uses a certain frequency point in the frequency hopping group to transmit and receive uplink and downlink links at a certain time according to a given rule.

In the prior art, one carrier includes 8 time slots, and each time slot can be configured as a TCH (Traffic Channel), a PDCH (Packet Data Channel), or a control channel. When a time slot is configured as a PDCH, the uplink of the PDCH is referred to as an uplink PDCH, and the downlink of the PDCH is referred to as a downlink PDCH, and up to eight user equipments can be multiplexed on the uplink PDCH or the downlink PDCH. The uplink PDCH or the downlink PDCH performs data transmission or transmission according to the RLC/MAC (Radio Link Control I Multiple Access Channel) block, and each RLC/MAC block includes 4 TDMAs (Time Division). Multiple Access, Time Division Multiple Access) frame. A user equipment can only perform data transmission and reception in one cell. When the user equipment accesses the cell, the base station controller performs uplink PDCH on one or more PDCHs of the cell and/or PDCH of the downlink PDCH according to the access request. The resource is assigned to this user. The PDCH resource may be described by the number of RLC/MAC blocks, or may be described by TBF (Temporary Block Flow). The PDCH can be distributed over one or more carriers of the cell. When performing PDCH resource allocation, one RLC/MAC block of one PDCH of one cell can be allocated to only one user equipment, which results in low flexibility of resource allocation.

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The embodiment of the present invention provides a resource management method, which is used for a network side device. The embodiment of the present invention is described by using a base station controller as an example, and does not refer to a base station controller. A base station controller, the base station controller can manage a plurality of base stations, and the management of the resources by the base station controller is generally implemented by each base station. As shown in FIG. 1, the resource management method includes:

Step 101: Receive an access request of the first user equipment.

The first user equipment in the cell requests the base station controller to allocate the PDCH resource by using the access request, that is, the first user equipment needs to use the PDCH for data transmission, and the access request is first sent to the location of the first user equipment. The corresponding base station is then transmitted to the base station controller through the base station. There is at least one PDCH in the logical carrier of the cell, and the cell is a logical cell, that is, all areas covered by the logical carrier.

The access request may be any one of the EGPRS (Enhanced General Packet Radio Service) packet channel request message, the packet channel request message or the channel request message sent by the first user equipment.

Step 102: Acquire, according to the access request, a communication resource required by the first user equipment.

The access request generally includes information such as the type of the access request sent by the first user equipment, or the terminal capability of the first user equipment. The base station controller determines, according to the access request, the physical carrier that the first user equipment can access and the PDCH resource that is required by the first user equipment. In this embodiment, the physical carrier that the first user equipment can access is the first A physical carrier.

Step 103: Allocate resources to the first user equipment in the available PDCH resources of the first physical carrier according to the communication resources required by the first user equipment, where the first physical carrier a physical carrier to be accessed by the first user equipment.

The available PDCH resources are preset. Before acquiring the available PDCH resources of the first physical carrier, the base station controller divides the available PDCH resources for each physical carrier in advance.

Optionally, before receiving the access request of the first user equipment, the base station controller needs to first allocate available PDCH resources for each physical carrier included in the cell where the first user equipment is located, and then can be in the first physical carrier. The first user equipment is allocated resources in the available PDCH resources. Generally, the available PDCH resources are composed of at least one radio link control/multiple access channel RLC/MAC block, or are composed of at least one uplink identifier USF. Or consisting of at least one temporary flow identifier TFI, that is, an available PDCH resource of each of the physical carriers is at least one RLC/MAC block; or at least one uplink identifier USF; or at least one identifier TFI is identified by at least one temporary flow. In a practical application, the base station controller may establish a resource admission table according to available PDCH resources of each physical carrier, where the resource admission table is used to record available PDCH resources of each physical carrier of the cell, and ensure that each physical carrier is available. PDCH resources, and there are no overlapping PDCH resources in the two physical carriers.

In this way, since the corresponding available PDCH resource is preset for each physical carrier, when the PDCH resource is allocated to the user equipment, the user equipment is allocated in the available PDCH resource corresponding to the physical carrier to be accessed by the user equipment. PDCH resources increase the flexibility of resource allocation.

It should be noted that, in the communication system, the cell may be divided into one or more location groups, and the configuration of each location group is consistent with the cell, and the configuration is a BCCH frequency, a carrier number, and the like. The partial configuration of the location group and the cell may also be different. For example, the number of carriers of the location group may be different from the number of carriers of the cell. Each cell includes one or more logical carriers, each location group includes one or more physical carriers, and each physical carrier in each location group corresponds to one of the logical carriers in the cell, and the correspondence of the carriers is a carrier The parameter configuration is the same, where the parameter configuration refers to the frequency of the carrier, and the channel type of each time slot of the carrier. In a practical application, the partial parameter configuration of the physical carrier corresponding to one logical carrier may also be different from the logical carrier. For example, the channel type of a certain time slot of the physical carrier may be different from the channel type of the logical carrier. One or more location groups may form one sector, and one cell may contain one or more sectors. It is assumed that the cell where the first user equipment is located occupies a resource of one frequency point, that is, the cell has one logical carrier, but the cell may have multiple location groups, and the carrier of each location group is called a physical carrier, and the physical carrier of all the location groups. A resource that shares a logical carrier. In this embodiment, the physical carrier where the first user equipment is located is the first physical carrier.

Providing the first physical carrier to be accessed by the first user equipment in the first user equipment

Before allocating resources on a PDCH resource, you need to first allocate available PDCH resources for each physical carrier in the cell.

For example, it is assumed that the cell where the first user equipment is located has a logical carrier, the logical carrier is a logical carrier A, the cell includes three location groups, the first location group includes a first physical carrier, and the second location group includes a second physical group. The carrier, the third location group includes a third physical carrier, and the first, second, and third physical carriers correspond to the logical carrier A. Initially, the first, second, and third location groups constitute sector A. In the prior art, one logical carrier may include 8 time slots, and the maximum configurable is 8 PDCHs. The uplink PDCH or the downlink PDCH of each PDCH may be multiplexed with up to 8 user equipments, and the foregoing PDCH may be multiplexed with 7 users. The device and the downlink PDCH can reuse 8 user equipments. When the first user equipment is allocated an uplink TBF, the first user equipment is also assigned a USF. Since each user equipment carries one TBF in the uplink, it can also be considered that the TBF carried by the first user equipment is also allocated. A USF. A unique USF is allocated for each user equipment or uplink TBF multiplexed on the uplink PDCH to distinguish different user equipments or uplink TBFs. The USF is carried in the downlink RLC/MAC block, and is used by the base station controller to indicate that the uplink PDCH is used to transmit the uplink RLC/MAC block in the next time period. In actual applications, the base station controller may be controlled by the base station. Any device that can perform this action. Each user equipment uses a TSC (Train Sequence Code) assigned to the user equipment by the base station controller when transmitting the uplink RLC/MAC block, and the TSC is a sequence of known sequences, the base station controller and the The user equipment corresponding to the base station controller carries a pre-specified TSC in the code modulated burst when transmitting the RLC/MAC block, and if the user equipment receives the burst signal, if the received burst If the signal includes the TSC, it can be determined to be a burst sent to itself. When the base station controller receives the burst signal, if the received burst signal uses the TSC, it can be determined that the user equipment sends Burst, therefore, The TSC can be used to distinguish between uplink and downlink RLC/MAC blocks sent by different user equipments. If the available PDCH resources of each physical carrier are composed of at least one RLC/MAC block, when initializing, the available PDCH resources allocated to each physical carrier are 1/3 of the logical carrier, and the available PDCH resources of each physical carrier. It is composed of at least one RLC/MAC block, taking the uplink PDCH of a certain PDCH of the logical carrier as an example. As shown in FIG. 2, every 52 TDMA frame periods of the uplink PDCH are called a 52 multiframe, and each of the The 52 multiframe is divided into 12 RLC/MAC blocks, and the RLC/MAC block numbers are B0 to B11. For example, the area 204 in FIG. 2 indicates the RLC/MAC block B0, and each RLC/MAC block occupies 4 frame periods. 204 is an RLC/MAC block, and the frame period is a period of each TDMA frame sent on the PDCH. In particular, s and X in FIG. 1 represent idle frames, and available PDCH resources of the uplink PDCH are pressed. The multi-frame is divided into two: The available PDCH resource of the first physical carrier is the resource 201, the available PDCH resource of the second physical carrier is the resource 202, and the available PDCH resource of the third physical carrier is the resource 203. In a practical application, the resource admission table may be composed of a first physical carrier, a resource 201, a second physical carrier, a resource 202, a third physical carrier, and a resource 203. It should be noted that the available PDCH resources on each PDCH may also be divided according to other granularities, such as the granularity of every 20 RLC/MAC blocks. The available PDCH resources occupied by each physical carrier may be proportionally divided. For example, the ratio of available PDCH resources occupied by the first physical carrier, the second physical carrier, and the third physical carrier is 1: 1 : 1 or 1: 2: 3 It is also possible to perform random allocation without limitation, which is not described in detail in the embodiments of the present invention. The ratio of available PDCH resources of different PDCHs to different physical carriers of the same logical carrier may be different. For example, the ratio of one uplink or downlink PDCH to three different physical carriers is 1: 1 : 1 , and another uplink or downlink The ratio of PDCH to three different physical carriers is 1:3:5.

If the available PDCH resources of each physical carrier are composed of at least one USF, the USF domain includes 3 bits, and 8 different values can be set. One USF indicates one user equipment, so each time slot can multiplex up to 8 users. The available PDCH resources for each physical carrier are composed of at least one USF. Taking a PDCH of the logical carrier as an example, the first physical carrier allocates USF=0~2 of the PDCH, the second physical carrier allocates USF=3~5 of the PDCH, and the third physical carrier allocates USF=6 of the PDCH. And USF=7. In practical applications, the resource access table The available PDCH resources of the recorded PDCH are divided into: a first physical carrier, USF=0~2; a second physical carrier, USF=3~5; a third physical carrier, USF=6 and USF=7. The available PDCH resources on different PDCHs of the same logical carrier may be allocated to different physical carriers in different manners. This embodiment is not described in detail herein.

If the available PDCH resources of the physical carriers are composed of at least one TFI, the TFI is an ID (identity, identity number identifier) that identifies the TBF, and corresponds to the TBF, and is used to identify the TBF on the uplink PDCH or the downlink PDCH. The TFI field consists of 5 bits and can be set to 32 different values. That is, for the same PDCH, the uplink PDCH can multiplex up to 32 uplink TBFs, and the downlink PDCH can multiplex up to 32 downlink TBFs. The available PDCH resources for each physical carrier are composed of at least one TFI. Taking a downlink PDCH of the logical carrier as an example, the first physical carrier allocates TFI=0~10 of the downlink PDCH, and the second physical carrier allocates TFI=11~20 of the downlink PDCH, and the third physical carrier allocates the downlink PDCH. TFI=21~31. In practical applications, the available PDCH resources of the downlink PDCH recorded in the resource admission table are divided into: a first physical carrier, TFI=0~10; a second physical carrier, TFI=11~20; Physical carrier, TFI=21~31. The available PDCH resources on different PDCHs of the same logical carrier can be allocated to different physical carriers in different manners. This embodiment is not described in detail herein.

It should be noted that the allocation of the available PDCH resources in this embodiment may be performed in units of one 52 multiframes, or in units of one slot or in units of one logical carrier. During the communication process, the load of the first physical carrier is constantly changing. When there are many user equipments accessing the first physical carrier, the available PDCH resources occupied by each physical carrier may be re-allocated, so that the user equipment is accessed. More physical carriers are allocated more available PDCH resources, and less available physical carriers for user equipment accessing less PDCH resources. Optionally, taking the first physical carrier as an example, the load of the first physical carrier may be first acquired, where the load of the first physical carrier is a PDCH resource occupied by a user equipment currently accessed by the first physical carrier. a ratio of the available PDCH resources of the first physical carrier, and then determining whether the load of the first physical carrier is greater than or equal to a re-allocation threshold, and if the load of the first physical carrier is greater than or equal to the re-allocation threshold, And then, according to the load of each physical carrier in the sector where the first user equipment is located, the available PDCH resources are separately allocated to the physical carriers, so that the available PDCH resources of the first physical carrier after being divided again are greater than or equal to that before the re-division Description The available PDCH resources of the first physical carrier. In an actual application, the base station controller may update the resource admission table according to the available PDCH resources of each physical carrier after being divided again.

It should be noted that, in the prior art, in some special communication systems, such as a railway communication system or a tunnel communication system, in order to fully utilize a limited frequency resource to cover a large area, a common cell technology is introduced, and the common cell is introduced. The technology refers to setting a location group of a plurality of different physical sites as one cell. A location group refers to a physical area covered by one or more physical carriers under the same site. The cell parameters such as the number of carriers and frequency points of each location group are the same. Each location group covers a certain area, and the continuous coverage area of multiple adjacent location groups is the coverage of the common cell. The common cell is managed by the base station controller. After the common cell technology is used, the total frequency points used by the same location group are reduced compared with the common cell technology, but the number of user equipments that can be carried by the entire cell is also reduced accordingly. . In the embodiment of the present invention, it is assumed that the cell in which the first user equipment is located is a cell after the common cell technology is used, and in order to increase the number of user equipments that can be carried by the cell, before the step 102, the cell where the first user equipment is located may also be used. When the current load is greater than or equal to the first splitting threshold, or when the number of currently accessed user equipments in the cell where the first user equipment is located is greater than or equal to the second splitting threshold, or when the cell coverage of the cell where the first user equipment is located is smaller than Or equal to the third splitting threshold, splitting the cell into at least two sectors, and then allocating available PDCH resources for each physical carrier included in the first sector in which the first user equipment is located, and in the second physical The first user equipment is allocated resources in the available PDCH resources of the carrier, and the second physical carrier is a physical carrier to be accessed by the first user equipment in the first sector.

For example, determining whether the current load of the cell of the cell where the first user equipment is located is greater than or equal to the first splitting threshold, and when the current load of the cell is greater than or equal to the first splitting threshold, the cell may be split into at least two sectors, when the current load of the cell If the first splitting threshold is smaller than the first splitting threshold, the cell may not be split into at least two sectors, and the current load of the cell is the ratio of the available PDCH resources occupied by the user equipment currently accessed by the cell to the total available PDCH resources, and the first The split threshold is preset according to a specific situation. For example, the first split threshold may be a cell capacity.

80%. In practical applications, the first splitting threshold may also be equal to 100%, or may be set to other proportional values according to actual network conditions.

Determining whether the number of currently accessed user equipments of the cell where the first user equipment is located is greater than or equal to The second splitting threshold is determined. When the number of the currently accessed user equipment of the cell is greater than or equal to the second splitting threshold, the cell may be split into at least two sectors. When the number of currently accessed user equipments of the cell is less than the second splitting threshold, The cell may not be split into at least two sectors, and the number of user equipments currently accessed by the cell is the number of user equipments currently accessed by the cell or the number of allocated TBFs, and the second split threshold is according to specific conditions. For example, the second split threshold may be a given value of 10. In actual applications, the split threshold may also be equal to the theoretical maximum accessible user equipment.

Determining whether the cell coverage of the cell where the first user equipment is located is less than or equal to the third splitting threshold, and determining, when the cell coverage of the cell is less than or equal to the third splitting threshold, the cell may be split into at least two sectors, when the cell The cell coverage is greater than the third splitting threshold, and the cell may not be split into at least two sectors, and the cell coverage of the cell is the level value of the cell in the measurement report reported by the user equipment, and the third split threshold is determined according to the specific situation. Preset, for example, the third split threshold may be a given level value 30. In practical applications, the third split threshold may also be equal to the theoretical maximum level value 63.

Before splitting the cell into at least two sectors, a split plan of the cell may be formulated according to the number of user equipments accessed by the cell and the distribution of the user equipment, where the split plan includes at least a physical carrier of the cell. The allocation method assigned to two of the sectors.

It is assumed that the cell in which the first user equipment is located includes a first logical carrier, and the first logical carrier includes three physical carriers, which are a first physical carrier, a second physical carrier, and a third physical carrier, respectively. Since the number of users accessing the first physical carrier is small, and the number of user equipments accessing the second physical carrier and the third physical carrier is large, the number of user equipments currently accessed by the cell and the distribution of user equipments are determined. It is planned that the splitting scheme in this embodiment divides the cell into two sectors, which are a first sector and a second sector, respectively, wherein the first sector includes a first physical carrier, and the second sector includes a second physical Carrier and third physical carrier.

The PDCH resource occupied by the first user equipment may be adjusted according to the splitting plan. The RLC/MAC block is used as an example for description.

Since the first sector and the second sector are required to be split according to the splitting scheme when the cell splitting is performed, the available PDCH resources of the first physical carrier before splitting are the RLC/MAC blocks B0 to B2 of the first logical carrier, and the second physical The available PDCH resources of the carrier are the first logical carrier. RLC/MAC blocks B3 to B8, the available PDCH resources of the third physical carrier are the RLC/MAC blocks B9~:B11 of the first logical carrier, and after performing the cell split according to the split plan, the second logical carrier and the third logical carrier are obtained. The available PDCH resources of the first physical carrier may be the RLC/MAC blocks B0~:B 11 of the second logical carrier, and the available PDCH resources of the second physical carrier are B0~:B5 of the third logical carrier, and the third physical carrier is available. The PDCH resource is B6-B 11 of the third logical carrier, assuming that the first user equipment accesses the RLC/MAC block B6 of the available PDCH resource of the second physical carrier, but after the cell splitting, the RLC/MAC block B6 is the third physical carrier. The PDCH resource is available, so before performing the cell splitting, the base station controller can adjust the PDCH resource occupied by the first user equipment, so that the first user equipment accesses the RLC/MAC block B3 of the available PDCH resource of the second physical carrier. Any one of the RLC/MAC blocks in B5, thereby avoiding resource conflicts when performing cell splitting.

When the current load of the cell where the first user equipment is located is greater than or equal to the first split threshold, or when the number of currently accessed user equipment of the cell where the first user equipment is located is greater than or equal to the second split threshold, or when When the cell coverage of the cell where the user equipment is located is less than or equal to the third splitting threshold, the cell may be split into at least two sectors, and the split may be split according to the split plan. For example, the current cell is configured with one PDCH, and the uplink PDCH user equipment accessing the PDCH occupies 7 USFs of a total of 8 USFs, and the current load is 87.5%. If the first split threshold is 80%, the load of the cell is greater than The first split threshold splits the cell into at least two sectors.

Assuming that the cell is split, there is a logical carrier, which is a first logical carrier. The logical carrier has three physical carriers, which are respectively a first physical carrier, a second physical carrier, and a third physical carrier, and eight times of the logical carrier. There are a time slots in the slot as PDCH, where a is an integer greater than or equal to 1 and less than or equal to 8.

If the available PDCH resources of the physical carriers are composed of at least one RLC/MAC block, the available PDCH resource allocation methods are the same for all the one time slots. For the same 52 multi-frame, the available PDCH resources of the first physical carrier are RLC/MAC block Β0~Β3, that is, the user equipment accessing the first physical carrier for data transmission service can only use the RLC/MAC blocks B0 B B3; the RLC/MAC block of the available PDCH resource of the second physical carrier is B4 ~B7, that is, the user equipment accessing the second physical carrier for data transmission service can only use RLC/MAC Blocks B4 to B7; the available PDCH resources of the third physical carrier are RLC/MAC blocks B8 to B11, that is, the user equipment accessing the second physical carrier for data transmission service can only use the RLC/MAC blocks B8 to B11. In practical applications, the resource admission table is composed of a first physical carrier, RLC/MAC blocks B0 to B3, a second physical carrier, RLC/MAC blocks B4 to B7, and a third physical carrier, RLC/MAC blocks B8 to: B11. The cell is split into two sectors, which are a first sector and a second sector, the first sector corresponds to the second logical carrier, and the second sector corresponds to the third logical carrier. The second logical carrier includes a first physical carrier, and the third logical carrier includes a second physical carrier and a third physical carrier. After the splitting, for the first sector, the available PDCH resources of the first physical carrier are RLC/MAC blocks B0 BBB 11 , and the user equipment accessing the first physical carrier may be transmitted on the RLC/MAC blocks B0 BBB 11 For the second sector, the base station controller allocates available PDCH resources for each physical carrier according to the load of the second physical carrier and the third physical carrier, and the available PDCH resources allocated by the large physical carrier are large, and the load is small. The available PDCH resources of the physical carrier allocation are small. For example, if the load of the second physical carrier is large, the available PDCH resources are RLC/MAC blocks B0 to B8; if the load of the third physical carrier is small, the available PDCH resources are B9~ B11. In an actual application, the time slot of the PDCH of the physical carrier after the splitting may be consistent with the time slot of the PDCH of the logical carrier corresponding to the splitting, or may be inconsistent. For example, after splitting, the second logical carrier becomes b time slots, where b is not equal to a and is an integer greater than or equal to 1 and less than or equal to 8.

If the available PDCH resources of the physical carriers are composed of at least one USF, the available PDCH resource allocation methods are the same for all the one time slots. For one uplink PDCH, the available PDCH resources of the first physical carrier are USF=0~ USF=2, that is, the user equipment accessing the first physical carrier can only use USF=0~USF=2 in each time slot; the available PDCH resource of the second physical carrier is USF=3~USF=5, that is, The user equipment entering the second physical carrier can only use USF=3~USF=5 in each time slot; the available PDCH resources of the third physical carrier are USF=6 and USF=7, that is, accessing the third physical carrier User equipment can only use USF=6 and USF=7 in each time slot. In a practical application, the resource admission table is composed of a first physical carrier, USF=0~USF=2; a second physical carrier, USF=3~USF=5; and a third physical carrier, USF=6 and USF=7. Since the cell can perform cell splitting, the cell is split into two sectors, which are a first sector and a second sector, and each sector corresponds to one logical carrier, that is, the first sector. The second logical carrier corresponds to the second logical carrier, and the second logical carrier includes the first physical carrier, and the third logical carrier includes the second physical carrier and the third physical carrier. After the splitting, for the first sector, the available PDCH resources of the first physical carrier are USF=0~USF=7 of each time slot in the 0~7 time slots of the TDMA frame, that is, accessing the first physical carrier. The user equipment may use USF=0~USF=7 for each time slot in a PDCH; for the second sector, the base station controller allocates available for each physical carrier according to the load of the second physical carrier and the third physical carrier. For a PDCH resource, the available PDCH resources of a large physical carrier are allocated, and the available PDCH resources of a small physical carrier are small. For example, the load of the second physical carrier is large, and the available PDCH resources are each time in a PDCH. USF=0~USF=5 of the slot; if the load of the third physical carrier is small, the available PDCH resources are USF=6 and USF=7 for each slot in a PDCH.

If the available PDCH resources of the physical carriers are composed of at least one TFI, the case of the cell splitting is similar to the case where the available PDCH resources of the physical carriers are composed of at least one USF, which is not detailed in this embodiment of the present invention.

In particular, the cell can be split into at least two sectors using space division plus orthogonal training sequence techniques. The space division plus orthogonal training sequence technology refers to allocating user equipments in different sectors, spatially isolating, and passing different user equipments or TBFs on two physical carriers of different sectors and the same frequency point. Different TSCs are allocated so that the base station can identify the uplink data of different user equipments, and the terminal can identify its own downlink data. Therefore, the cell is split by the space division plus orthogonal training sequence technology, so that better interference isolation is formed between the logical carriers of the at least two sectors obtained after the splitting. Different user equipments or TBFs on two physical carriers of different sectors and the same frequency point can use the same USF or the same TFI. The two different TSCs assigned are as theoretically orthogonal or nearly orthogonal to achieve optimal performance.

Further, after splitting the cell into at least two sectors, the available PDCH resources are allocated for each physical carrier in the sector according to the load of each physical carrier in each of the sectors.

After the division of the foregoing steps, the physical carrier corresponding to each sector after the cell splitting is divided into corresponding available PDCH resources according to the load of the physical carrier. In an actual application, the resource admission table may be updated according to the result obtained after the division, and the updated resource admission table includes a cell. The available PDCH resources corresponding to the physical carrier and physical carrier of each sector after the split.

In particular, if the time slot of the PDCH of the physical carrier after the splitting is consistent with the time slot of the PDCH of the logical carrier corresponding to the splitting in the process of splitting the cell, the data may be determined when the data transmission amount of the first user equipment is large. Whether the amount of data of the first user equipment stored in the cache area is greater than a preset capacity threshold, and when the amount of data is greater than the preset capacity threshold, acquiring the logical carrier of the at least two sectors The occupied first resource is again allocated to the first user equipment. The cache area is the same as the RLC/MAC block identifier of the second resource occupied by the first user equipment before the re-allocation. The first resource is the same as the parameter configuration of the logical carrier where the second resource is located, and the first resource and the second resource may be an RLC/MAC block, or may be a USF or a TFI, but the same user must be allocated. The first resource and the second resource of the same type.

If the available PDCH resources of the physical carriers are composed of at least one RLC/MAC block, it is assumed that the sector in which the first user equipment is located after the split is the first sector, and the second physical carrier is allocated to the second physical carrier. The resource is the RLC/MAC block is B0, but the data transmission amount of the first user equipment is large, and the data to be transmitted in the buffer area exceeds the capacity threshold, the base station controller may use the RLC/MAC block B0 of the second sector. The first resource is allocated to the first user equipment for transmitting data, where the RLC/MAC block B0 of the second sector is an available PDCH resource in the same physical carrier as the parameter configuration of the first physical carrier of the second sector. For example, it can be obtained according to the resource admission table stored in the base station controller.

If the available PDCH resources of the physical carriers are composed of at least one USF, the sector in which the first user equipment is located after the split is the first sector, and the second physical carrier is allocated to the second physical carrier. The resource is the USF=0 of the slot 0 in the first physical carrier. When the data transmission amount of the first user equipment is greater than or equal to the capacity threshold, the base station controller may configure the second sector to be the same as the first physical carrier parameter. The USF=0 of 0 of the physical carrier is allocated as the first resource to the first user equipment for transmitting data.

If the available PDCH resources of the physical carriers are composed of at least one TFI, the case where the first resource is allocated to the user equipment is similar to the available PDCH resource of each physical carrier, which is composed of at least one USF. More details. After the cell is split into at least two sectors, it is further determined whether the first sector is capable of performing cell splitting, where the first sector is a sector in which the first user equipment is located, and the first sector is a Determining any one of the at least two sectors, that is, when the number of access user equipments of the first sector is greater than or equal to a second splitting threshold, or the load of the first sector is greater than or equal to a first splitting threshold or first When the coverage of the sector is less than or equal to the third splitting threshold, the first sector is split into at least two sub-sectors, and the splitting of the first sector is performed in the same manner as the splitting of the cell, where Do not repeat them.

Optionally, when the load in the cell is greater than the preset load threshold, dynamic channel switching may be performed, where dynamic channel switching refers to configuring one time slot of the TCH (Traffic Channel) on the logical carrier of the cell. When the load in the cell is less than or equal to the preset load threshold, dynamic channel release can be performed. Dynamic new arrival refers to converting one of the time slots configured as PDCH on the logical carrier of the cell into a TCH.

For example, after the resource is allocated to the first user equipment on the physical carrier, the base station controller may send, by using a signaling message, the available PDCH resource allocated by each physical carrier after the splitting to the first user equipment, the signaling message. Can be "Packet Downlink Assignment", "Multiple TBF Downlink Assignment", "Packet Uplink Assignment", "Multiple TBF Uplink Assignment" ", "Packet Timeslot Reconfigure;", "Multiple TBF Timeslot Reconfigure;", "Immediate Assignment", "Packet CS Release Indication" Any one of the indications, such as the TFI, the USF, the time slot number, etc., may be carried by the foregoing signaling message, and only the uplink, downlink, or uplink PDCH resource information, such as TFI, USF, and slot number, may be carried as the first user equipment. Information. If the PDCH resource is allocated on multiple physical carriers, it will also contain the physical payload. Numbering.

Further, after the cell is split into at least two sectors, if at least two user sectors are accessed in the cell, and at least two sectors of communication resources cannot be fully utilized, the at least two fans may also be determined. Whether there are sectors in the zone that satisfy the merge condition. For example, determining whether a sector that satisfies a merge condition exists in the at least two sectors may be determined by whether there is a sector in the at least two sectors that has a current load that is less than or equal to a first merge threshold. Said to Determining, in less than two sectors, a sector whose current load is less than or equal to the first merge threshold, determining that there are sectors in the at least two sectors that satisfy the merge condition, when all of the at least two sectors The sector current load of the sector is greater than the first merge threshold, and it is determined that there is no sector that satisfies the merge condition in the at least two sectors. In the actual application, the first merge threshold is set according to a specific situation, where the sector is set. The current load is the ratio of the available PDCH resources occupied by the user equipment currently accessed by the sector to the total available PDCH resources. The number of the current access user equipments in the at least two sectors may be less than or equal to the second. Merging the sector of the threshold to determine that there is a sector in which the number of currently accessed user equipments of the sector is less than or equal to the second merge threshold, and determining that the at least two sectors meet the merge condition a sector, when the number of sectors currently accessed by all sectors of the at least two sectors is greater than a second merge threshold, determining that the at least two sectors do not exist The merging condition of the sector, in the actual application, the second merging threshold is set according to a specific situation, the number of the currently accessed user equipment of the sector is the number of user equipments currently accessed by the sector; or may pass the at least two Determining whether there is a sector in which the cell coverage is greater than or equal to the third merge threshold is determined, and if there are sectors in the at least two sectors that have a cell coverage greater than or equal to the third merge threshold, determining the at least two A sector that satisfies a merge condition exists in a sector, and when a sector cell coverage of all sectors in the at least two sectors is smaller than a third merge threshold, determining that the at least two sectors do not meet the merge condition In the actual application, the third merge threshold is set according to a specific situation, and the cell coverage of the sector is the level value of the sector in the measurement report reported by the user equipment.

If there are sectors in the at least two sectors that satisfy the merge condition, the sectors need to be merged, and before the merge, at least two sectors are first acquired from the current sector of the cell, the at least two The sector includes at least one sector that satisfies the merge condition, that is, the obtained sector that needs to be merged may be a sector that satisfies the merge condition, or only one sector satisfies the merge condition, and the rest is None of the sectors satisfying the merge condition. The selection of the merged sector is set according to the specific situation in the actual application, and the present invention does not limit this.

After acquiring the sectors that need to be merged, the selected at least two sectors are merged. Since the available PDCH resources of the physical carriers of each sector are different, the base station controller also needs to adjust the PDCH resources occupied by the user equipments that access the physical carriers before the merging, so as to avoid resources in the process of merging. The phenomenon of conflict. The resource management method provided by the embodiment of the present invention manages the PDCH resource of the cell according to the sector, so that each physical carrier occupies a reasonable communication resource, and when the cell can perform cell splitting, the cell is split into at least two. a sector, the parameter configuration of the logical carrier existing in each sector is the same as the parameter configuration of the logical carrier existing in the pre-split cell, so that the communication resources available to the cell are increased by at least one time, and when the sector satisfies the merge condition, The merging of at least two sectors saves communication resources, and therefore, the flexibility of the resource allocation manner is improved compared to the prior art. The embodiment of the present invention provides a resource management method, where the network side device performs resource allocation, and the base station controller is used as an example for description. The base station controller is not limited to the base station controller. As shown in FIG. 3, the method includes: Step 301: Determine whether it is required The first user equipment adjusts the PDCH resources.

In the actual application, when the first user equipment occupies the PDCH resource for data transmission, the base station controller may also adjust the PDCH resource occupied by the first user equipment according to actual needs. For example, when the data transmission amount of the first user equipment is greater than or equal to the preset threshold, the base station controller determines that the first user equipment needs to allocate more PDCH resources for data transmission; when the cell where the first user equipment is located needs to perform cell splitting When the cell is split, the base station controller determines that the PDCH resource occupied by the first user equipment needs to be adjusted, so as to avoid resource conflict in the process of cell splitting.

Step 302: Acquire a communication resource required by the first user equipment.

Depending on the situation, the base station controller can determine the PDCH resources that the first user equipment needs to adjust. In the process of adjustment, the existing non-PDCH slots may need to be converted into PDCH slots to increase the existing PDCH resources. It may be necessary to allocate more RLC/MAC block numbers to the first user equipment.

Obtaining a physical carrier to be accessed by the first user equipment and a PDCH resource required by the first user equipment, according to a final judgment result of the base station controller and a parameter configuration of a logical carrier of the first cell where the first user equipment is located, It is assumed that the first cell includes the first logical carrier, and the first physical carrier includes the first physical carrier and the second physical carrier, and the first physical device and the second physical carrier have the same parameter configuration, and the first user equipment can access the first Physical carrier or second physical carrier. Step 303: Obtain the available PDCH resources of the first physical carrier and the second physical carrier that the first user equipment can access.

Optionally, before acquiring the available PDCH resources of the first physical carrier and the second physical carrier, the base station controller needs to allocate a time slot configured as a PDCH for the first physical carrier and the second physical carrier, respectively, for each physical carrier. Each PDCH partition can use PDCH resources. The available PDCH resources of the first physical carrier and the second physical carrier may be composed of at least one RLC/MAC block; or consist of at least one uplink identification USF; or consist of at least one TFI. In an actual application, after the allocation is completed, the allocated result is stored in the resource admission table, and the base station controller may obtain the available PDCH resources of the first physical carrier and the second physical carrier through the resource admission table.

Step 304: Allocate resources for the first user equipment in the available PDCH resources of the first physical carrier and the second physical carrier.

The base station controller may allocate the PDCH resource to the first user equipment according to the PDCH resources required by the first user equipment, the available PDCH resources of the first physical carrier, and the available PDCH resources of the second physical carrier. It should be noted that, since the parameter configurations of the first physical carrier and the second physical carrier are the same, the first user equipment can occupy the PDCH resource of the first physical carrier or the PDCH resource of the second physical carrier, so the base station controls The device may allocate the PDCH resource to the first user equipment only on the first physical carrier, or may allocate the PDCH resource to the first user equipment on the second physical carrier, or may simultaneously be the first physical carrier and the second physical carrier. The first user equipment allocates a PDCH resource. When the PDCH resource is allocated to the first user equipment on the first physical carrier and the second physical carrier, the PDCH resources may be allocated to the first user equipment on the first physical carrier and the second physical carrier, respectively. Assigned to the first user device.

Step 305: Notify the first user equipment of the allocated PDCH resource.

After the PDCH resource is allocated to the first user equipment, the base station controller may notify the first user equipment of the PDCH resource allocated by the first user equipment by using a signaling message, where the signaling message may be "Packet Downlink Assignment", "Multiple TBF" Downlink Assignment ", "Packet Uplink Assignment", "Multiple TBF Uplink Assignment", "Packet Timeslot Reconfigure", " Multiple TBF Timeslot One of the Reconfigure", "Immediate Assignment", "Packet CS Release Indication", etc., may carry the uplink and downlink PDCH resource information, such as TFI, USF, and slot number, allocated for the first user equipment by using the foregoing signaling message. Etc. If the PDCH resource is allocated on multiple physical carriers, the physical carrier number is also included.

The resource management method provided by the embodiment of the present invention is that the network side device allocates communication resources according to the specific conditions of the user equipment access, and improves the flexibility of the resource allocation manner compared with the prior art. The embodiment of the present invention provides a resource management method, where the network side device performs resource merging. The embodiment of the present invention uses a base station controller as an example for description. As shown in FIG. 4, the method includes:

Step 401: Determine whether a sector included in the cell meets a merge condition.

At the time of merging, at least two of the sectors included in the cell need to be merged into one sector. Therefore, before merging, it is first necessary to traverse all the sectors included in the cell, and it is judged whether each sector satisfies the merging condition.

Optionally, determining whether the sector meets the merging condition may be determined by whether the current load of the sector is less than or equal to the first merging threshold, where the current load of the sector is an available PDCH resource occupied by the user equipment currently accessed by the sector. The ratio of the total available PDCH resources, for example, the first merge threshold may be set to 30%. In an actual application, the first merging threshold is set according to a specific situation, and has no relative relationship with the first splitting threshold, and may be smaller than the first splitting threshold, which is not limited by the embodiment of the present invention.

The judging whether the sector meets the merging condition may also be determined by whether the number of the current access user equipment of the sector is less than or equal to the second merging threshold. The number of the current access users of the sector is the number of user equipments currently accessed by the sector. Or the number of allocated TBFs, for example, the second merge threshold may be a given value of 10. In actual application, the second merge threshold is set according to a specific situation, and has no relative relationship with the second split threshold. It may be smaller than the second splitting threshold, which is not limited by the embodiment of the present invention.

The determining whether the sector meets the merging condition may also be determined by whether the current coverage of the sector is greater than or equal to the third merging threshold, where the current coverage of the sector is the level value of the cell in the measurement report reported by the user equipment in the sector. For example, the third merge threshold may be a given The level value is 30. In an actual application, the third merge threshold is set according to a specific situation, and has no relative relationship with the third split threshold, and may be larger than the third split threshold.

For example, there are three sectors under the cell, sector 1, sector 2, sector 3, each sector is configured with two logical carriers, and sector 1 corresponds to logical carrier 1, logical carrier 2, and sector 2 corresponds to Logical carrier 3, logical carrier 4, sector 3 corresponding logical carrier 5, logical carrier 6, and logical carrier 1, logical carrier 3 and logical carrier 5 have the same parameter configuration, logical carrier 2, logical carrier 4 and logical carrier 6 The parameter configuration is the same. The description is made by determining whether the sector satisfies the merge condition by whether the current load of the sector is less than or equal to the first merge threshold. When the load of the sector is less than or equal to the first merge threshold, the sector satisfies the merge condition, and each sector The load situation is as shown in 1.

Table 1 Load information of each sector before merging

Table 1 records the logical carrier included in sector 1, sector 2, and sector 3, the first merge threshold, the sector load of each sector, and whether the merge condition is satisfied. Table 1 shows the sector. The load of 1 is 25%, which is smaller than the first merge threshold corresponding to the sector. Therefore, the merge condition is satisfied; the load of sector 2 is 30%, which is equal to the first merge threshold corresponding to the sector, and therefore the merge condition is satisfied; The load of zone 3 is 30%, which is greater than the first merge threshold corresponding to the sector, and therefore does not satisfy the merge condition.

Step 402: Select a sector to be merged according to the judgment result of the merge condition.

If the sector in the sector included in the cell satisfies the merging condition, it may be determined that sector merging is needed to make full use of the communication resources, and in the process of merging, it may be selected to satisfy the combination. At least two sectors of the condition are combined, and at least one sector that satisfies the merge condition may be selected to be merged with at least one sector that does not satisfy the merge condition.

For the sectors shown in Table 1, Sector 1 and Sector 2 can be selected for merging during the merging process. It is also possible to select sector 1, sector 2 and sector 3 for merging. You can also select sector 1 and sector 3 for merging. The specific merging scheme is determined according to the specific situation, and the embodiment of the present invention does not limit this.

It should be noted that the process of merging at least two sub-sectors into a new sub-sector in the actual application is the same as the process of merging the sectors into a new sector, which is not described in the embodiment of the present invention.

Step 403: Perform sector consolidation according to the selected merged sector.

The process of performing sector merging is described by taking the combination of sector 1 and sector 2 as an example. After performing sector merging, sector 4 and sector 3 are obtained, and the merged situation is as follows.

Table 2 Load information of each sector after merging

Table 2 records information such as the logical carriers included in sector 4 and sector 3, the corresponding first merge threshold, the sector load of each sector, and the conditions for re-merging. It can be seen from Table 2 that the logical carrier corresponding to sector 4 is logical carrier 7 and logical carrier 8, and the sector load of the sector is 27.5%, which is less than the first merge threshold of 30%, which satisfies the sector combining condition; sector 3 The corresponding logical carriers are logical carrier 5 and logical carrier 6. The sector load of the sector is 30%, which is greater than the first merge threshold by 20%, and the sector merge condition is not satisfied. At this time, the merging of the sector 4 and the sector 3 can be performed as needed.

It should be noted that, before combining the sector 1 and the sector 2, the PDCH resources occupied by the user equipments that are using the PDCH resources in the sector 1 and the sector 2 need to be adjusted to avoid the resources after the sector is merged. conflict. For example, if the available PDCH resource is composed of at least one RLC/MAC block, it is assumed that user equipment 1 performs data transmission under sector 1 before combining, and user equipment 2 performs data transmission under sector 2, sector 1 and sector. The resource adjustment of Zone 2 is shown in Table 3.

Table 3 Resource adjustment information for each sector

Table 3 records the details of the resource adjustments of the sector 1 and the sector 2. The resources occupied by the user equipments before the resource adjustment are as shown in the column of the pre-merger resource occupation in Table 2, and are occupied by the user equipment after the resource adjustment. The resources are shown in the "Resource Usage Adjustment" column of Table 2. As can be seen from Table 3, the user equipment 1 occupies the RLC/MAC blocks B0 to B5 of the slot 6 of the logical carrier 1 before the resource adjustment, and the user equipment 2 occupies the RLC/MAC of the slot 6 of the logical carrier 3 before the resource adjustment. Blocks B3 to B8. After the resource adjustment, the user equipment 1 occupies the RLC/MAC blocks B0 to B4 of the slot 6 of the logical carrier 1, and the user equipment 2 occupies the RLC/MAC blocks B5 to B8 of the slot 6 of the logical carrier 3. After the adjustment is completed, the base station controller notifies the user equipment 1 and the user equipment 2 of the allocated PDCH resources by signaling, and the signaling may be "Packet Downlink Assignment", "Multiple TBF Downlink Assignment", "Packet Uplink Assignment", One of "Multiple TBF Uplink Assignment", "Packet Timeslot Reconfigure", "Multiple TBF Timeslot Reconfigure", "Real Assignment", "Packet CS Release Indication", etc. The uplink and downlink PDCH resource information allocated by the backup device 1 and the user equipment 2, such as TFI, slot number, and the like. If the PDCH resource is allocated on multiple carriers, the carrier number is also included. If the uplink PDCH resource is allocated, the USF needs to be included.

When the sector 1 and the sector 2 are combined, the logical carrier 1 and the logical carrier 3 are combined into one logical carrier 7. At this time, the user equipment 1 and the user equipment 2 share the resources of the logical carrier 7, and the specific merged occupied resource information. As shown in Table 4.

Table 4 Resource allocation information after consolidation of each sector

Table 4 records the case where the resource allocation of the user equipment 1 and the user equipment 2 after the sector 1 and the sector 2 are combined to obtain the sector 4 and the sector 3. Since the user equipment 1 occupies the RLC/MAC blocks B0 B B4 of the slot 6 of the logical carrier 1 after the resource adjustment, the user equipment 2 occupies the RLC/MAC blocks B5 B B8 of the slot 6 of the logical carrier 3, which can be obtained from Table 4. After the combination of the sector 4 and the sector 3, the logical carrier 1 and the logical carrier 3 are combined into a logical carrier 7, and the user equipment 1 occupies the RLC/MAC blocks B0 to B4 of the time slot 6 of the logical carrier 7, the user The device 2 occupies the RLC/MAC blocks B5 to B8 of the time slot 6 of the logical carrier 7, and thus, it can be seen that after the resource adjustment, the user equipment 1 and the user equipment 2 are all used in the logical carrier 7 during the merging process. Resource conflict caused by RLC/MAC blocks B3 to B5 of slot 6.

If the available PDCH resources are composed of at least one USF or TFI, resource-adjusted The process and the merge process are the same as the resource adjustment process and the merge process in which the available PDCH resources are at least one RLC/MAC block, which will not be described in detail in the present invention.

The resource management method provided by the embodiment of the present invention performs the merging of at least two sectors when the sector satisfies the merging condition, saves communication resources and ensures the quality of the data transmission service of the user equipment compared with the prior art. , improved user experience. Assuming that the user equipment is a user equipment for data transmission, after the common cell technology is used, the cell managed by the base station controller of the current cell Y includes three location groups, namely, a location group A, a location group B, and a location group C, where The group A, the location group B, and the location group C may be distributed on multiple base stations on one base station, and the base station controller performs resource division on the physical carriers of the location group A, the location group B, and the location group C. The user equipments of the location group A, the location group B, and the location group C are allocated by the base station corresponding to each location group. The physical carrier of the location group A is the physical carrier D1 and the physical carrier E1. The physical carrier of group B is physical carrier D2 and physical carrier E2; the physical carrier of location group C is physical carrier D3, physical carrier E3, and the cell has two logical carriers, which are respectively a first logical carrier and a second logical carrier, wherein The physical carrier included in the first logical carrier is physical carrier D1, physical carrier D2 and physical carrier D3, and the physical carrier included in the second logical carrier is physical Carrier E1, physical carrier E2 and physical carrier E3. User device F is located in location group A. The embodiment of the present invention provides a resource management method, which is used for a network side device. The embodiment of the present invention uses a base station controller as an example, and does not refer to a base station controller. As shown in FIG. 5, the method includes:

Step 501: Receive an access request of the user equipment F, and perform step 502.

The access request may be a "Packet Resource Request", an "EGPRS Packet Channel Request", a "Packet Channel Request", or a "Channel" transmitted by the first user equipment. Request (message or channel request message).

Optionally, before step 501, the available PDCH resources of the physical carrier D1, the physical carrier D2, the physical carrier D3, the physical carrier E1, the physical carrier E2, and the physical carrier E3 are first allocated.

If the available PDCH resources of each physical carrier are by at least one RLC/MAC block group For a 52 multiframe period, after demarcation, the available PDCH resources of the physical carrier D1 are the RLC/MAC blocks B0 to B2 of all PDCHs of the first logical carrier, and the available PDCH resources of the physical carrier D2 are the first. RLC/MAC blocks B3 to B8 of all PDCHs of the logical carrier, the available PDCH resources of the physical carrier D3 are the RLC/MAC blocks B9~: B11 of all PDCHs of the first logical carrier; the available PDCH resources of the physical carrier E1 are the second logic RLC/MAC blocks B0 to B3 of all PDCHs of the carrier, available PDCH resources of the physical carrier E2 are RLC/MAC blocks B4 to B7 of all PDCHs of the second logical carrier, and available PDCH resources of the physical carrier E3 are the second logical carrier RLC/MAC block B8~B 11 of all PDCH. In practical applications, the resource admission table stored by the base station controller is composed of the above information.

If the available PDCH resources of the physical carriers are composed of at least one USF, after being divided, the available PDCH resources of the physical carrier D1 are USF=0~USF=2 for each channel of all the PDCHs of the first logical carrier. The available PDCH resource of the physical carrier D2 is USF=3~USF=5 for each channel of all PDCHs of the first logical carrier, and the available PDCH resource of the physical carrier D3 is USF= for each channel of all PDCHs of the first logical carrier. 6 and USF=7; the available PDCH resources of the physical carrier E1 are USF=0 and USF=1 of each channel of all PDCHs of the second logical carrier, and the available PDCH resources of the physical carrier E2 are all PDCHs of the second logical carrier. USF=2~USF=4 for each channel, and the available PDCH resource of physical carrier E3 is USF=5~USF=7 for each channel of all PDCHs of the second logical carrier. In practical applications, the resource admission table stored by the base station controller is composed of the above information.

If the available PDCH resources of the physical carriers are composed of at least one TFI, the resource allocation is similar to the available PDCH resources of the physical carriers, which is composed of at least one USF.

Step 502: Allocate resources to the user equipment F according to the access request of the user equipment F, and perform step 503.

Generally, the access request includes information about the type of the access request, the terminal capability, and the like, and the base station controller determines, according to the access request of the user equipment F, the physical carrier to be accessed by the user equipment F. Since the location group A receives the access request of the user equipment F, the base station controller allocates resources for the user equipment F in the available PDCH resources of the physical carrier D1 and the physical carrier E1. If the available PDCH resources of the physical carriers are composed of at least one RLC/MAC block, the user equipment F requests to establish an uplink TBF, and the base station controller allocates PDCH resources for the user equipment F, and there are three allocation modes:

The first allocation method is to allocate an uplink TBF on the physical carrier D1. The TBF includes a slot number configured as a PDCH, one slot corresponding to one PDCH, and a specified USF and TFI. If the RLC/MAC block B0 in a 52 multiframe period of the PDCH is assigned to the user equipment F, the other user equipment or TBF multiplexed on the PDCH of the physical carrier D1 will not be able to use B0.

The second allocation method is to allocate an uplink TBF on the physical carrier D1. The TBF includes a plurality of slot numbers configured as PDCHs, each time slot corresponding to one PDCH, and a specified USF and TFI. If the RLC/MAC block B0 within one 52 multiframe period of one of the PDCHs is assigned to the user equipment F, the other user equipment or TBF multiplexed on the same PDCH of the physical carrier D1 will not be able to use B0.

The third allocation method is to allocate an uplink TBF on the physical carriers D1 and E1. The TBF includes a plurality of slot numbers configured as PDCHs, each time slot corresponding to one PDCH, and a specified USF and TFI. If the RLC/MAC block B0 in one 52 multiframe period of one or more PDCHs on the physical carrier D1 is assigned to the user equipment F for use, the other user equipment or TBF multiplexed on the same PDCH of the physical carrier D1 will Cannot use B0. If the RLC/MAC block B1 in one 52 multiframe period of one or more PDCHs on the physical carrier E1 is assigned to the user equipment F for use, the other user equipment or TBF multiplexed on the same PDCH of the physical carrier E1 will Can't use Bl.

If the available PDCH resources of each physical carrier are composed of at least one USF, the user equipment F requests to establish an uplink TBF, and the base station controller allocates PDCH resources for the user equipment F, and there are also three allocation methods:

The first allocation method is to allocate an uplink TBF on the physical carrier D1. The TBF includes a slot number configured as a PDCH, one slot corresponding to one PDCH, and a specified USF and TFI. If the USF=0 of the PDCH is assigned to the user equipment F, the other user equipment or TBF multiplexed on the PDCH of the physical carrier D1 will not be able to use USF=0.

The second allocation method is to allocate an uplink TBF on the physical carrier D1, and the TBF includes multiple The slot number configured as the PDCH, each time slot corresponds to one PDCH, and also includes the specified USF and TFI. If USF=0 of one of the PDCHs is assigned to the user equipment F, the other user equipment or TBF multiplexed on the PDCH of the physical carrier D1 will not be able to use USF=0.

The third allocation method is to allocate an uplink TBF on the physical carriers D1 and E1. The TBF includes a plurality of slot numbers configured as PDCHs, each time slot corresponding to one PDCH, and a specified USF and TFI. If USF=0 of one or more PDCHs on physical carrier D1 is assigned to user equipment F, other user equipment or TBFs multiplexed on the same PDCH of physical carrier D1 will not be able to use USF=0. If USF=1 of one or more PDCHs on physical carrier E1 is assigned to user equipment F, other user equipment or TBFs multiplexed on the same PDCH of physical carrier E1 will not be able to use USF=1.

If the available PDCH resources of each physical carrier are composed of at least one TFI, the user equipment F requests to establish an uplink TBF, and the base station controller allocates a PDCH resource for the user equipment F, and there are also three allocation modes:

The first allocation method is to allocate an uplink TBF on the physical carrier D1. The TBF includes a slot number configured as a PDCH, one slot corresponding to one PDCH, and a specified USF and TFI. If the TFI=0 of the PDCH is assigned to the user equipment F, the other user equipment or TBF multiplexed on the PDCH of the physical carrier D1 will not be able to use TFI=0.

The second allocation method is to allocate an uplink TBF on the physical carrier D1. The TBF includes a plurality of slot numbers configured as PDCHs, each time slot corresponding to one PDCH, and a specified USF and TFI. If the TFI=0 of the PDCH is assigned to the user equipment F, the other user equipment or TBF multiplexed on the same PDCH of the physical carrier D1 will not be able to use TFI=0.

The third allocation method is to allocate an uplink TBF on the physical carriers D1 and E1, the TBF includes a plurality of slot numbers configured as PDCH, each time slot corresponds to one PDCH, and further includes a specified USF and TFI. If TFI=0 of one or more PDCHs on physical carrier D1 is assigned to user equipment F for use, other user equipment or TBFs multiplexed on the same PDCH of physical carrier D1 will not be able to use TFI=0. If TFI=0 on the physical carrier El is assigned to the user equipment F for use, other user equipment or TBFs multiplexed on the same PDCH of the physical carrier E1 will not be able to use TFI=0. Step 503: Determine whether the current number of user equipments in the cell Y is greater than or equal to a second splitting threshold. When the number of the current user equipment of the cell Y is greater than or equal to the second splitting threshold, step 504 is performed, and when the current number of user equipments of the cell Y is less than the second splitting threshold, step 505 is performed.

For example, after the user equipment F accesses the physical carrier D1, the base station controller counts the number of user equipments that are currently carried by the two logical carriers in the cell Y, if the number of user equipments currently carried by the cell Y is greater than or equal to the second. When the threshold is split, the cell Y is split. For example, the second splitting threshold may be 80% of the number of user equipments that can be carried by the cell γ, or may be 100%. In actual applications, it may be determined according to specific conditions, and the embodiment of the present invention does not do this. limited.

It should be noted that the determining condition of the cell splitting may also be determining whether the current load of the cell is greater than or equal to the first splitting threshold. If the current load of the cell is greater than or equal to the first splitting threshold, the cell can perform cell splitting; The cell coverage of the cell may be determined to be less than or equal to the third splitting threshold. If the cell coverage of the cell is less than or equal to the third splitting threshold, the cell can perform cell splitting.

Step 504: The cell Y is split into at least two sectors.

Before splitting the cell Y into at least two sectors, it is first necessary to adjust the PDCH resources occupied by the user equipment currently accessed by the cell Y to avoid resource conflicts during the splitting process.

When the current number of user equipments in the cell Y is greater than or equal to the second splitting threshold, the cell Y may be split into two sectors by using a space division plus orthogonal training sequence technique, which are respectively sector Y1 and sector. Y2, using the space division plus orthogonal training sequence technology, can achieve better interference isolation between the logical carriers of the at least two sectors obtained after the splitting.

The sector Y1 includes a location group A, and there are two logical carriers, which are a first logical carrier A1 and a second logical carrier G1, respectively, and the sector Y2 includes a location group B and a location group C, and there are also two The logical carriers are respectively the first logical carrier A2 and the second logical carrier G2, and the parameter configurations of the first logical carrier A1 and the first logical carrier A2 are the same as the parameter configuration of the first logical carrier. After the cell Y is split, the available PDCH resources of each physical carrier are also re-divided. If the available PDCH resources of the physical carriers are composed of at least one RLC/MAC block, the available PDCH resources are re-divided according to the load of each physical carrier, and the PDCH resources are divided according to the 52 multiframe period, and the available PDCH resources of the physical carrier D1 are obtained. RLC/MAC block B0~:B11 of a logical carrier A1, the available PDCH resource of the physical carrier E1 is the RLC/MAC block B0~B11 of the second logical carrier G1, and the available PDCH resource of the physical carrier D2 is the first logical carrier A2 The RLC/MAC blocks B0 to B6, the available PDCH resources of the physical carrier D3 are the RLC/MAC blocks B7~:B11 of the first logical carrier A2, and the available PDCH resources of the physical carrier E2 are the RLC/MAC blocks of the second logical carrier G2. B0 to B5, the available PDCH resources of the physical carrier E3 are the RLC/MAC blocks B6 to B11 of the second logical carrier G2. In an actual application, the base station controller may update the resource admission table according to the available PDCH resources of the re-divided physical carriers, and the information recorded in the updated resource admission table is as described above.

If the available PDCH resources of the physical carriers are composed of at least one USF, the available PDCH resources are re-divided according to the load of each physical carrier, and the available PDCH resources of the physical carrier D1 are obtained as each of all the PDCHs of the first logical carrier A1. USF=0~USF=7 of the PDCH, the available PDCH resource of the physical carrier E1 is USF=0~USF=7 of each PDCH of all PDCHs of the second logical carrier G1, and the available PDCH resource of the physical carrier D2 is the first logic USF=0~USF=3 for each PDCH of all PDCHs of carrier A2, and available PDCH resources of physical carrier D3 are USF=4~USF=7 for each PDCH of all PDCHs of the first logical carrier A2, physical carrier E2 The available PDCH resource is USF=0~USF=4 for each PDCH of all PDCHs of the second logical carrier G2, and the available PDCH resources of the physical carrier E3 are USF=5 for each PDCH of all PDCHs of the second logical carrier G2. ~USF=7, in actual application, the base station controller can update the resource access table according to the available PDCH resources of the re-divided physical carriers, and update the resource access table record. Information as described above.

If the available PDCH resources of the physical carriers are composed of at least one TFI, the resource re-division is similar to the available PDCH resources of the physical carriers, and is not detailed in this embodiment of the present invention.

After the resource re-division is completed, the base station controller sends the resource allocation information to each base station by using a signaling message, and then each base station sends the user equipment to the user equipment currently accessing the base station. It should be noted that, in actual applications, the time slot of the PDCH of the physical carrier after the splitting may be consistent with the time slot of the PDCH of the logical carrier corresponding to the splitting, or may be inconsistent.

Step 505: Keep the current state of the cell Y unchanged.

Step 506: Receive an access request of the user equipment H, and perform step 507.

Generally, the access request includes location information of the user equipment H. After receiving the request, the base station controller can determine, according to the location information of the user equipment H, which sector the user equipment H is in, and set the user equipment H to be located. Sector Yl.

Step 507: According to the access request of the user equipment, allocate resources to the at least two sector logical carriers for the user equipment, and perform step 508.

The RLC/MAC block is allocated to the user equipment 两个 in two physical carriers of the sector Y1 according to the access request of the user equipment Η.

4. The user equipment Η accesses the physical carrier D1. If the available PDCH resources of each physical carrier are composed of at least one RLC/MAC block, the base station controller may use the RLC/MAC block B0~: B11 of the first logical carrier A1. One of the RLC/MAC blocks is allocated to the user equipment H, assuming that the RLC/MAC block to which the user equipment is allocated is B0; if the available PDCH resources of the respective physical carriers are composed of at least one USF, the base station controller may One of the USF=0~USF=7 of each time slot of the first logical carrier A1 is allocated to the user equipment H; if the available PDCH resources of each physical carrier are composed of at least one TFI, The case where the user equipment H allocates resources is similar to the available PDCH resources of the physical carriers, which is composed of at least one USF, which is not detailed in this embodiment of the present invention.

In particular, if the time slot of the PDCH of the physical carrier is the same as the time slot of the PDCH of the logical carrier corresponding to the pre-split, in the process of cell splitting, if the user equipment H is allocated resources after the split, if the user equipment H The data transmission amount is large, and it can be determined whether the data amount of the user equipment H stored in the buffer area is greater than a preset capacity threshold, and when the data quantity is greater than the preset capacity threshold, the data is acquired in the logical carrier of at least two sectors. The unoccupied first resource is again allocated to the first user equipment.

For example, if the available PDCH resources of the respective physical carriers are composed of at least one RLC/MAC block, the unoccupied RLC/MAC block B0 in the physical carrier D2 of the sector Y2 is obtained as the first RLC/MAC block. Assigned to user device H again, then The user equipment H is allocated to the RLC/MAC block identified by the same RLC/MAC block of the same logical carrier using two parameters for data transmission; if the available PDCH resources of each physical carrier are composed of at least one USF, The unoccupied USF in the physical carrier D2 of the sector Y2 is allocated as the second USF to the user equipment H, and the user equipment H is allocated to the same time slot in which the same logical carrier is configured using two parameters. USF is used for data transmission; if the available PDCH resources of each physical carrier are composed of at least one TFI, the case of re-allocating resources for user equipment H is similar to the available PDCH resources of each physical carrier being composed of at least one USF, The embodiments of the invention will not be described in detail.

Further, the user equipment F can also perform the data quantity judgment and the resource reallocation process. The specific process refers to the data quantity judgment and the resource reallocation process of the user equipment H, and the present invention will not be described in detail.

Step 508: Determine whether the sector Y1 and the sector Y2 satisfy the merge condition. If there are sectors satisfying the merge condition in the sector Y1 and the sector Y2, perform step 509; if the sector Y1 and the sector Y2 do not exist, the merge is satisfied. For the conditional sector, go to step 505.

For example, after allocating the PDCH resource to the user equipment H, the base station controller separately counts the number of user equipments carried by the two logical carriers of the sector Y1 and the sector Y2, if the user equipment currently carried by the sector Y1 or the sector Y2 If the number is less than or equal to the second merge threshold, the sector Y1 or the sector Y2 satisfies the merge condition, and the second merge threshold may be 50% of the number of user equipments that the sector Y1 or the sector Y2 can carry at most In the actual application, the setting is performed according to the specific situation, which is not limited by the embodiment of the present invention.

It should be noted that the condition for combining the sector Y1 or the sector Y2 may also be determining whether the current load of the sector Y1 or the sector Y2 is less than or equal to the first merge threshold, if the current load of the sector Y1 or the sector Y2 is less than or equal to The first merge threshold, the sector Y1 or the sector Y2 can perform cell splitting; the judgment condition of the sector Y1 or the sector Y2 being combined may also be determining whether the cell coverage of the sector Y1 or the sector Y2 is greater than or equal to the third merge. Threshold, if the cell coverage of sector Y1 or sector Y2 is less than or equal to the third merge threshold, then sector Y1 or sector Y2 can perform cell splitting.

In the fourth embodiment of the present invention, after the PDCH resource is allocated to the user equipment H, the sector Y1 satisfies the merge condition, and the sector Y2 does not satisfy the merge condition. Step 509: Select a sector to be merged, and perform step 510.

According to the judgment of step 508, the sector to be merged is selected. Since there are only sector Y1 and sector Y2 in this embodiment, only sector Y1 and sector Y2 can be selected to be merged. In practical applications, more options can be selected. The sectors are merged, wherein all the sectors in the multiple sectors may satisfy the merge condition, or at least one sector satisfies the merge condition, and the remaining sectors do not satisfy the merge condition, and the merged sectors are merged according to specific conditions. The embodiment of the present invention does not limit this.

Step 510: Combine sectors.

The sectors that need to be merged in step 509 are sector Y1 and sector Y2. Before combining sector Y1 and sector Y2, it is first required to occupy the user equipment currently accessed by sector Y1 and sector Y2. The PDCH resources are adjusted to avoid resource conflicts during the merge process.

After the resource adjustment is completed, the sector Y1 and the sector Y2 are merged. After the combination, the cell W is obtained, and the available PDCH resources of the physical carriers in the cell W are allocated according to the number and distribution of the user equipments. After the resource allocation is completed, the base station controller sends the available PDCH resources of each physical carrier to the user equipment currently accessed by the cell W by using a signaling message.

It should be noted that, when the number of current user equipments of the sector exceeds the second split threshold of the sector, the sector may also be split. Taking the sector Y1 as an example, it is first determined whether the sector Y1 can be performed. The cell is split, that is, whether the number of access user equipments of the sector Y1 is greater than or equal to the second split threshold, whether the load of the sector Y1 is greater than or equal to the first split threshold, and whether the coverage of the sector Y1 is less than or equal to the third. Split threshold. If the sector Y1 is capable of cell splitting, that is, the number of access user equipments of the sector Y1 is greater than or equal to the second splitting threshold or the load of the sector Y1 is greater than or equal to the first splitting threshold or the coverage of the sector Y1 is less than or equal to When the third splitting threshold is used, the sector Y1 is split into at least two sub-sectors, and the splitting method of the sector Y1 is the same as the splitting method of the cell Y, and is not described herein, but the cell Y is finally The number of sectors obtained by splitting is less than or equal to the number of physical carriers present in the cell Y.

When the load in the cell Y is greater than the preset load threshold, dynamic channel switching is performed; when the load in the cell Y is less than or equal to the preset load threshold, dynamic channel release is performed.

It should be noted that the sequence of the steps of the resource management method provided by the embodiment of the present invention is Appropriate adjustments can be made, and the steps can also be increased or decreased according to the situation, for example, the steps

503 can also be executed before step 501. Any method that can be easily conceived within the technical scope of the present invention is well within the scope of the present invention, and therefore will not be described again. .

The resource management method provided by the embodiment of the present invention allocates the communication resources of the logical carrier according to the load of each physical carrier, so that each physical carrier occupies a reasonable communication resource, and when there are many user devices accessing the PDCH in the cell, The cell is split to obtain at least two sectors, and the parameter configuration of the logical carrier existing in each sector is the same as the parameter configuration of the logical carrier existing in the pre-split cell, so that the available RLC/MAC block of the cell is at least doubled. And the user equipment that can be indicated by a USF in the cell is also increased by at least one time. Moreover, when there are sectors in the cell that meet the merge condition, performing sector merging saves communication resources and ensures the quality of the data transmission service of the user equipment. Therefore, compared with the prior art, the resource management is improved. Sex. The embodiment of the present invention provides a resource management device 60, as shown in FIG. 6, including: a receiving unit 601, configured to receive an access request of a first user equipment.

The access request received by the receiving unit 601 may be any one of the EGPRS packet channel request message, the packet channel request message or the channel request message sent by the first user equipment.

The obtaining unit 602 is configured to obtain, according to the access request received by the receiving unit 601, a communication resource required by the first user equipment.

The access request generally includes information such as a type of the request message sent by the first user equipment, a terminal capability of the first user equipment, and the like. The obtaining unit 602 determines, according to the access request, a physical carrier that the first user equipment can access and a PDCH resource required by the physical carrier, The physical carrier that the first user equipment can access in this embodiment is the first physical carrier. The first allocating unit 603 is configured to allocate resources to the first user equipment in the available packet data channel PDCH resource of the first physical carrier according to the communication resource required by the first user equipment acquired by the acquiring unit 602. The first physical carrier is a physical carrier to be accessed by the first user equipment.

The available PDCH resources are preset, and the base station controller divides the available PDCH resources for each PDCH in advance, and the available PDCH resources of each of the PDCHs may be composed of at least one RLC/MAC block; or by at least one uplink Identify the USF component; or consist of at least one TFI. Therefore, the available PDCH resources of the first physical carrier may be at least one RLC/MAC block, or at least one USF, or at least one TFI.

Optionally, before receiving the access request of the first user equipment, the available PDCH resources are first allocated for each physical carrier included in the cell where the first user equipment is located. Generally, the available PDCH resource is composed of at least one radio link control/multiple access channel RLC/MAC block, or is composed of at least one uplink identifier USF, or at least one temporary flow identifier TFI, that is, each said The available PDCH resources of the physical carrier are at least one RLC/MAC block; or at least one uplink identifier USF; or at least one is identified by at least one temporary flow TFI. In a practical application, the base station controller may establish a resource admission table according to available PDCH resources of each physical carrier, where the resource admission table is used to record available PDCH resources of each physical carrier of the cell, and ensure that each physical carrier is available. PDCH resources, and there are no overlapping PDCH resources in the two physical carriers.

In this way, since the corresponding available PDCH resource is preset for each physical carrier, when the receiving unit receives the request for allocating the PDCH resource to the user equipment, the acquiring unit first acquires the available physical carrier corresponding to the user equipment to be accessed. The PDCH resource allocates PDCH resources to the user equipment in the available PDCH resources corresponding to the physical carrier to be accessed by the user equipment acquired by the acquiring unit, thereby improving the flexibility of the resource allocation manner.

It should be noted that, in the communication system, the cell may be divided into one or more location groups, and the configuration of each location group is consistent with the cell, and the configuration is a BCCH (Broadcast Control Channel) frequency, a number of carriers, and the like. The partial configuration of the location group and the cell may also be different. For example, the number of carriers in the location group may be different from the number of carriers in the cell. Each cell contains one One or more logical carriers, each location group includes one or more physical carriers, and each physical carrier in each location group corresponds to one of the logical carriers in the cell, and the correspondence of the carriers is the same as the parameter configuration of the carrier. The parameter configuration refers to the frequency of the carrier and the channel type of each slot of the carrier. In a practical application, the partial parameter configuration of the physical carrier corresponding to one logical carrier may also be different from the logical carrier. For example, the channel type of a certain time slot of the physical carrier may be different from the channel type of the logical carrier. One or more location groups may form one sector, and one cell may contain one or more sectors.

For example, before allocating resources on the available PDCH resources of the first physical carrier to which the first user equipment is to be accessed, the resource management device 60 first needs to allocate available PDCH resources for each physical carrier of the cell.

Assume that the cell in which the first user equipment is located has a logical carrier, the logical carrier is a logical carrier A, the cell includes three location groups, the first location group includes a first physical carrier, and the second location group includes a second physical carrier, The three-position group includes a third physical carrier, and the first, second, and third physical carriers correspond to the logical carrier A. Initially, the first, second, and third location groups constitute sector A. In the prior art, one logical carrier may include 8 time slots, and the maximum is configurable to 8 PDCHs. Up to 8 user equipments may be multiplexed in the uplink PDCH or the downlink PDCH of each PDCH, and 7 users may be multiplexed in the PDCH as above. The device and the downlink PDCH can reuse 8 user equipments. When the first user equipment is allocated an uplink TBF, the first user equipment is also assigned a USF. Since each user equipment carries one TBF on the uplink, it can also be considered as the TBF assignment carried by the first user equipment. A USF. A unique USF is allocated for each user equipment or uplink TBF multiplexed on the uplink PDCH, so as to distinguish different user equipments or uplink TBFs. The USF is carried in the downlink RLC/MAC block, and is used by the base station controller to indicate that the uplink PDCH is used to transmit the uplink RLC/MAC block in the next time period. In actual applications, the base station controller may be controlled by the base station. Any device that can perform this action. Each user equipment uses a TSC (Train Sequence Code) assigned to the user equipment by the base station controller when transmitting the uplink RLC/MAC block, the TSC is a sequence of known sequences, the base station controller and the When the user equipment corresponding to the base station controller sends the RLC/MAC block, the coded modulated burst carries a pre-specified TSC, and when the user equipment receives the burst signal If the received burst signal contains the TSC, it can be determined to be a burst sent to itself. When the base station controller receives the burst signal, if the received burst signal is used, the The TSC can be determined to be a burst sent by the user equipment. Therefore, the TSC can be used to distinguish between the uplink and downlink RLC/MAC blocks sent by different user equipments.

If the available PDCH resources of each physical carrier are composed of at least one RLC/MAC block, when initializing, the available PDCH resources allocated to each physical carrier are 1/3 of the logical carrier, and the available PDCH resources of each physical carrier. It is composed of at least one RLC/MAC block, taking the uplink PDCH of a certain PDCH of the logical carrier as an example. As shown in FIG. 2, every 52 TDMA frame periods of the uplink PDCH are called a 52 multiframe, and each of the The 52 multiframe is divided into 12 RLC/MAC blocks, and the RLC/MAC block numbers are B0 to B11. For example, the area 204 in FIG. 2 indicates the RLC/MAC block B0, and each RLC/MAC block occupies 4 frame periods. 204 is an RLC/MAC block, and the frame period is a period of each TDMA frame sent on the PDCH. In particular, s and X in FIG. 1 represent idle frames, and available PDCH resources of the uplink PDCH are pressed. The multi-frame is divided into two: The available PDCH resource of the first physical carrier is the resource 201, the available PDCH resource of the second physical carrier is the resource 202, and the available PDCH resource of the third physical carrier is the resource 203. In practical applications, the resource admission table may be composed of a first physical carrier, a resource 201, a second physical carrier, a resource 202, a third physical carrier, and a resource 203. It should be noted that the available PDCH resources on each PDCH can also be divided according to other granularities, such as the granularity of every 20 RLC/MAC blocks. The available PDCH resources occupied by each physical carrier may be proportionally divided. For example, the ratio of available PDCH resources occupied by the first physical carrier, the second physical carrier, and the third physical carrier is 1: 1 : 1 or 1: 2: 3 It is also possible to perform random allocation without limitation, which is not described in detail in the embodiments of the present invention. The ratio of available PDCH resources of different PDCHs to different physical carriers of the same logical carrier may be different. For example, the ratio of one uplink or downlink PDCH to three different physical carriers is 1: 1 : 1 , and another uplink or downlink The ratio of PDCH to three different physical carriers is 1:3:5.

If the available PDCH resources of each physical carrier are composed of at least one USF, the USF domain includes 3 bits, and 8 different values can be set. One USF indicates one user equipment, so each time slot can multiplex up to 8 users. The available PDCH resources for each physical carrier are Made up of at least one USF. Taking a PDCH of the logical carrier as an example, the first physical carrier allocates USF=0~2 of the PDCH, the second physical carrier allocates USF=3~5 of the PDCH, and the third physical carrier allocates USF=6 of the PDCH. And USF=7. In practical applications, the available PDCH resources of the PDCH recorded in the resource admission table are divided into: a first physical carrier, USF=0~2; a second physical carrier, USF=3~5; a third physical carrier, USF=6 and USF=7. The available PDCH resources on different PDCHs of the same logical carrier may be allocated to different physical carriers in different manners. This embodiment is not described in detail herein.

If the available PDCH resources of the physical carriers are composed of at least one TFI, the TFI is an ID (identity, identity number identifier) that identifies the TBF, and corresponds to the TBF, and is used to identify the TBF on the uplink PDCH or the downlink PDCH. The TFI field consists of 5 bits and can be set to 32 different values. That is, for the same PDCH, the uplink PDCH can multiplex up to 32 uplink TBFs, and the downlink PDCH can multiplex up to 32 downlink TBFs. The available PDCH resources for each physical carrier are composed of at least one TFI. Taking a downlink PDCH of the logical carrier as an example, the first physical carrier allocates TFI=0~10 of the downlink PDCH, and the second physical carrier allocates TFI=11~20 of the downlink PDCH, and the third physical carrier allocates the downlink PDCH. TFI=21~31. In an actual application, the available PDCH resources of the downlink PDCH recorded in the resource admission table are divided into: a first physical carrier, TFI=0~10; a second physical carrier, TFI=11~20; a third physical carrier, TFI=21 ~31. The available PDCH resources on different PDCHs of the same logical carrier can be allocated to different physical carriers in different manners. This embodiment is not described in detail herein.

As shown in FIG. 7, the resource management device 60 further includes:

The second allocating unit 604 is configured to allocate available PDCH resources for each physical carrier included in the cell where the first user equipment is located.

The load of the first physical carrier is greater than or equal to the re-allocation threshold, and the available PDCH resources are separately allocated for the physical carriers according to the load of each physical carrier in the sector in which the first user equipment is located.

It should be noted that, in the prior art, in some special communication systems, such as a railway communication system or a tunnel communication system, in order to fully utilize a limited frequency resource to cover a large area, a common cell technology is introduced, and the common cell is introduced. The technology refers to setting a location group of a plurality of different physical sites as one cell. A location group refers to a physical area covered by one or more physical carriers under the same site. The cell parameters such as the number of carriers and frequency points of each location group are the same. Each location group covers a certain area, and the continuous coverage area of multiple adjacent location groups is the coverage of the common cell. The common cell is managed by the network side device. After the common cell technology is used, the total number of frequency points used by the same location group is reduced compared with the common cell technology, but the number of user equipments that can be carried by the entire cell is also reduced. . In the embodiment of the present invention, it is assumed that the cell in which the first user equipment is located is a cell after the common cell technology is used. In order to increase the number of user equipments that can be carried by the cell, before or after allocating communication resources for the first user equipment, Whether the cell where the first user equipment is located can perform cell splitting.

The second allocation unit 604 is further configured to allocate available PDCH resources to respective physical carriers included in the first sector where the first user equipment is located, where the first sector is in the at least two sectors. Any sector.

It should be noted that before the cell is split into at least two sectors, a cell splitter may be determined according to the number of user equipments accessed by the cell and the distribution of user equipment. The splitting plan includes a mode in which the physical carrier of the cell is allocated to at least two of the sectors, and the PDCH resource occupied by the first user equipment may be adjusted according to a split plan, so as to avoid appearing when performing cell splitting. Resource conflicts.

The splitting unit 605 is specifically configured to split the cell into at least two sectors by using a space division plus orthogonal training sequence technique. The space division plus orthogonal training sequence technology refers to allocating user equipments in different sectors, spatially isolating, and passing different user equipments or TBFs on two physical carriers of different sectors and the same frequency point. Different TSCs are allocated so that the base station can identify the uplink data of different user equipments, and the terminal can identify its own downlink data. Therefore, the cell is split by the space division plus orthogonal training sequence technology, so that better interference isolation is formed between the logical carriers of the at least two sectors obtained after the splitting. Different user equipments or TBFs on two physical carriers of different sectors and the same frequency point can use the same USF or the same TFI. The two different TSCs assigned are as theoretically orthogonal or nearly orthogonal to achieve optimal performance.

In particular, if the time slot of the PDCH of the physical carrier after the splitting is consistent with the time slot of the PDCH of the logical carrier corresponding to the splitting, the first allocating unit 603 may also be used to determine that the storage is in the cache. Whether the data amount of the first user equipment of the area is greater than a preset capacity threshold; when the data quantity is greater than the preset capacity threshold, acquiring an unoccupied first in a logical carrier of the at least two sectors A resource is allocated to the first user equipment again, and the first resource is the same as the identifier of the second resource occupied by the first user equipment before the re-allocation, where the first resource and the second resource are located The parameter configuration of the logical carrier is the same.

Optionally, when the load in the cell is greater than a preset load threshold, the resource management device 60 may further For dynamic channel switching, dynamic channel switching refers to configuring the cell logical carrier as

One of the time slots of the TCH (Traffic Channel) is converted into a PDCH; when the load in the cell is less than or equal to the preset load threshold, a dynamic channel release can be performed, and the dynamic new arrival refers to the cell logical carrier. One of the time slots configured as PDCH is converted to TCH.

Further, as shown in FIG. 9, after the cell can be split and the cell is split into at least two sectors, if at least two user devices are accessed in the cell, at least two cannot be fully utilized. The resource management device 60 further includes a merging unit 606, where the merging unit 606 is configured to have a current load of the sector in the sector included in the cell that is less than or equal to the first merge threshold. a sector, or when there is a sector in the sector included in the cell that has a current number of access user equipments less than or equal to a second merge threshold, or when there is a cell coverage in a sector included in the cell When a sector greater than or equal to the third merge threshold, at least two sectors are acquired from the sector included in the cell, and the at least two sectors include at least one of the sectors satisfying the merge condition, where The current load of the cell is the proportion of the PDCH resources occupied by the currently accessed user equipment in the available PDCH resources of the cell, and the cell coverage of the cell is the user equipment. Report the measurement level value of a cell, said at least two sectors will then merge.

The resource management device provided by the embodiment of the present invention manages the cell PDCH resource according to the sector, so that each physical carrier occupies a reasonable communication resource, and when the determining unit determines that the cell can perform cell splitting, the splitting unit splits the cell. Obtaining at least two sectors, the parameter configuration of the logical carrier existing in each sector is the same as the parameter configuration of the logical carrier existing in the pre-split cell, so that the available communication resources of the cell are increased by at least one time, and the sector meets the merge In the condition, at least two sectors are combined, which saves communication resources, and therefore, the flexibility of the resource allocation manner is improved compared with the prior art. The embodiment of the present invention provides a resource management device 100, as shown in FIG. 10, including: a receiver 1001, configured to receive an access request of a first user equipment.

The first user equipment in the cell requests the base station controller to allocate PDCH resources by using the access request, that is, the first user equipment needs to use the PDCH for data transmission, where the The incoming request is first sent to the base station corresponding to the location of the first user equipment, and then transmitted to the base station controller through the base station. There is at least one PDCH in the logical carrier of the cell, and the cell is a logical cell, that is, all areas covered by the logical carrier.

The access request received by the receiver 1001 may be any one of the EGPRS packet channel request message, the packet channel request message or the channel request message sent by the first user equipment.

The processor 1002 is configured to acquire, according to the access request received by the receiver 1001, a communication resource required by the first user equipment, where the processor 1002 is further configured to be required according to the first user equipment. The communication resource is configured to allocate resources to the first user equipment in an available PDCH resource of the first physical carrier, where the first physical carrier is a physical carrier to be accessed by the first user equipment.

The access request generally includes information such as the type of the access request sent by the first user equipment, or the terminal capability of the first user equipment. The processor 1002 determines, according to the access request, the physical carrier that the first user equipment can access and the PDCH resource that is required by the first user equipment. In this embodiment, the physical carrier that the first user equipment can access is the first A physical carrier.

The available PDCH resources are pre-set. Before acquiring the available PDCH resources of the first physical carrier, the resource management device 100 pre-defines available PDCH resources for each PDCH, and the available PDCH resources of each of the PDCHs may be Composing at least one RLC/MAC block; or consisting of at least one uplink identifier USF; or consisting of at least one TFI. Therefore, the available PDCH resources of the first physical carrier may be at least one RLC/MAC block, or at least one USF, or at least one TFI.

Optionally, before receiving the access request of the first user equipment, the processor 1002 needs to first allocate available PDCH resources to each physical carrier included in the cell where the first user equipment is located. Generally, the available PDCH resources. Consists of at least one radio link control/multiple access channel RLC/MAC block, or consists of at least one uplink identifier USF, or consists of at least one temporary flow identifier TFI, ie, available PDCH resources for each of the physical carriers Is at least one RLC/MAC block; or at least one uplink identifier USF; or at least one is identified by at least one temporary flow TFI. In practical applications, the processor 1002 can be A resource admission table is established for the available PDCH resources of each physical carrier, where the resource admission table is used to record available PDCH resources of each physical carrier of the cell, and ensure that each physical carrier has available PDCH resources, and the two physical entities There are no overlapping PDCH resources available for the carrier.

In this way, since the corresponding available PDCH resource is preset for each physical carrier, when the receiver receives the request for allocating the PDCH resource to the user equipment, the processor first acquires the available physical carrier corresponding to the user equipment to be accessed. The PDCH resource allocates PDCH resources to the user equipment in the available PDCH resources corresponding to the physical carrier to be accessed by the user equipment, which improves the flexibility of the resource allocation manner.

It should be noted that, in the communication system, the cell may be divided into one or more location groups, and the configuration of each location group is consistent with the cell, and the configuration is a BCCH frequency, a carrier number, and the like. The partial configuration of the location group and the cell may also be different. For example, the number of carriers in the location group may be different from the number of carriers in the cell. Each cell includes one or more logical carriers, each location group includes one or more physical carriers, and each physical carrier in each location group corresponds to one of the logical carriers in the cell, and the correspondence of the carriers is a carrier The parameter configuration is the same, where the parameter configuration refers to the frequency of the carrier, and the channel type of each time slot of the carrier. In practical applications, the partial parameter configuration of the physical carrier corresponding to a logical carrier may also be different from the logical carrier. For example, the channel type of a certain slot of the physical carrier may be different from the channel type of the logical carrier. One or more location groups may form one sector, and one cell may contain one or more sectors.

For example, before allocating resources on the available PDCH resources of the first physical carrier to be accessed by the first user equipment, the processor 1002 first needs to allocate available PDCH resources for each physical carrier in the cell.

For example, the processor 1002 is further configured to allocate available PDCH resources to each physical carrier included in the cell where the first user equipment is located. Generally, the available PDCH resources are controlled/multiple connected by at least one radio link. An incoming RLC/MAC block, or consists of at least one uplink identifier USF, or consists of at least one temporary flow identifier TFI, that is, an available PDCH resource of each physical carrier is at least one RLC/MAC block; or at least One uplink identifier USF; or at least one identified by at least one temporary flow TFI. In an actual application, the processor 1002 may record the available PDCH resources of the respective physical carriers in a resource admission table, and the first physical carrier recorded in the resource admission table is available. A resource is allocated to the first user equipment in the PDCH.

Assume that the cell in which the first user equipment is located has a logical carrier, the logical carrier is a logical carrier A, the cell includes three location groups, the first location group includes a first physical carrier, and the second location group includes a second physical carrier, The three-position group includes a third physical carrier, and the first, second, and third physical carriers correspond to the logical carrier A. Initially, the first, second, and third location groups are grouped into sector A. In the prior art, one logical carrier may include 8 time slots, and the maximum is configurable to 8 PDCHs. Up to 8 user equipments may be multiplexed in the uplink PDCH or the downlink PDCH of each PDCH, and 7 users may be multiplexed in the PDCH as above. The device and the downlink PDCH can reuse 8 user equipments. When the first user equipment is allocated an uplink TBF, the first user equipment is also assigned a USF. Since each user equipment carries one TBF on the uplink, it can also be considered as the TBF assignment carried by the first user equipment. A USF. A unique USF is allocated for each user equipment or uplink TBF multiplexed on the uplink PDCH to distinguish different user equipments or uplink TBFs. The USF is carried in the downlink RLC/MAC block, and is used by the base station controller to indicate that the uplink PDCH is used to transmit the uplink RLC/MAC block in the next time period. In actual applications, the base station controller may be controlled by the base station. Any device that can perform this action. Each user equipment uses a TSC (Train Sequence Code) assigned to the user equipment by the base station controller when transmitting the uplink RLC/MAC block, the TSC is a sequence of known sequences, the base station controller and the The user equipment corresponding to the base station controller carries a pre-specified TSC in the code modulated burst when transmitting the RLC/MAC block, and if the user equipment receives the burst signal, if the received burst If the signal includes the TSC, it can be determined to be a burst sent to itself. When the base station controller receives the burst signal, if the received burst signal uses the TSC, it can be determined that the user equipment sends The burst, therefore, the TSC can be used to distinguish between the uplink and downlink RLC/MAC blocks transmitted by different user equipments.

If the available PDCH resources of each physical carrier are composed of at least one RLC/MAC block, when initializing, the available PDCH resources allocated to each physical carrier are 1/3 of the logical carrier, and the available PDCH resources of each physical carrier. It is composed of at least one RLC/MAC block, taking the uplink PDCH of a certain PDCH of the logical carrier as an example. As shown in FIG. 2, every 52 TDMA frame periods of the uplink PDCH are called a 52 multiframe, and each of the 52 multiframe division In the case of 12 RLC/MAC blocks, the RLC/MAC block numbers are B0 to B11. For example, the area 204 in FIG. 2 indicates the RLC/MAC block B0, and each RLC/MAC block occupies 4 frame periods. The indication 204 is an RLC/MAC block, and the frame period is a period of each TDMA frame sent on the PDCH. In particular, s and X in FIG. 1 represent idle frames, and available PDCH resources of the uplink PDCH are performed in 52 multiframes. The available PDCH resource of the first physical carrier is the resource 201, the available PDCH resource of the second physical carrier is the resource 202, and the available PDCH resource of the third physical carrier is the resource 203. In actual application, the resource access table may be A physical carrier, a resource 201; a second physical carrier, a resource 202; a third physical carrier, a resource 203. It should be noted that the available PDCH resources on each PDCH may also be divided according to other granularities, such as the granularity of every 20 RLC/MAC blocks. The available PDCH resources occupied by each physical carrier may be proportionally divided. For example, the ratio of available PDCH resources occupied by the first physical carrier, the second physical carrier, and the third physical carrier is 1: 1 : 1 or 1: 2: 3 It is also possible to perform random allocation without limitation, which is not described in detail in the embodiments of the present invention. The ratio of available PDCH resources of different PDCHs to different physical carriers of the same logical carrier may be different. For example, the ratio of one uplink or downlink PDCH to three different physical carriers is 1: 1 : 1 , and another uplink or downlink The ratio of PDCH to three different physical carriers is 1:3:5.

If the available PDCH resources of each physical carrier are composed of at least one USF, the USF domain includes 3 bits, and 8 different values can be set. One USF indicates one user equipment, so each time slot can multiplex up to 8 users. The available PDCH resources for each physical carrier are composed of at least one USF. Taking a PDCH of the logical carrier as an example, the first physical carrier allocates USF=0~2 of the PDCH, the second physical carrier allocates USF=3~5 of the PDCH, and the third physical carrier allocates USF=6 of the PDCH. And USF=7. In practical applications, the available PDCH resources of the PDCH recorded in the resource admission table are divided into: a first physical carrier, USF=0~2; a second physical carrier, USF=3~5; a third physical carrier, USF=6 and USF=7. The available PDCH resources on different PDCHs of the same logical carrier can be allocated to different physical carriers in different manners. This embodiment is not described in detail herein.

If the available PDCH resources of the physical carriers are composed of at least one TFI, the TFI is an ID (identity, identity number identifier) that identifies the TBF, and corresponds to the TBF. Used to identify the TBF on the uplink PDCH or the downlink PDCH. The TFI field consists of 5 bits and can be set to 32 different values. That is, for the same PDCH, the uplink PDCH can multiplex up to 32 uplink TBFs, and the downlink PDCH can multiplex up to 32 downlink TBFs. The available PDCH resources for each physical carrier are composed of at least one TFI. Taking a downlink PDCH of the logical carrier as an example, the first physical carrier allocates TFI=0~10 of the downlink PDCH, and the second physical carrier allocates TFI=11~20 of the downlink PDCH, and the third physical carrier allocates the downlink PDCH. TFI=21~31. In an actual application, the available PDCH resources of the downlink PDCH recorded in the resource admission table are divided into: a first physical carrier, TFI=0~10; a second physical carrier, TFI=11~20; a third physical carrier, TFI=21 ~31. The available PDCH resources on different PDCHs of the same logical carrier can be allocated to different physical carriers in different manners. This embodiment is not described in detail herein.

The processor 1002 is further configured to acquire a load of the first physical carrier, where a load of the first physical carrier is a PDCH resource occupied by a user equipment currently accessed by the first physical carrier, and the first physical medium is occupied by the first physical a ratio of available PDCH resources of the carrier, and then determining whether the load of the first physical carrier is greater than or equal to a redistribution threshold, and if the load of the first physical carrier is greater than or equal to the re-allocation threshold, according to the first user equipment The load of each physical carrier in the sector in which the PDCH resource is allocated for each physical carrier. In a practical application, the processor 1002 may update the resource admission table according to the available PDCH resources of the respective physical carriers that are subdivided.

It should be noted that, in the prior art, in some special communication systems, such as a railway communication system or a tunnel communication system, in order to fully utilize a limited frequency resource to cover a large area, a common cell technology is introduced, and the common cell is introduced. The technology refers to setting a location group of a plurality of different physical sites as one cell. A location group refers to a physical area covered by one or more physical carriers under the same site. The cell parameters such as the number of carriers and frequency points of each location group are the same. Each location group covers a certain area, and the continuous coverage area of multiple adjacent location groups is the coverage of the common cell. The common cell is managed by the network side device. After the common cell technology is used, the total number of frequency points used by the same location group is reduced compared with the common cell technology, but the number of user equipments that can be carried by the entire cell is also reduced. . In the embodiment of the present invention, it is assumed that the cell in which the first user equipment is located is a cell after the common cell technology is used. In order to increase the number of user equipments that can be carried by the cell, before or after allocating communication resources for the first user equipment, Determine whether the cell where the first user equipment is located can perform cell splitting.

The processor 1002 is further configured to: when the current load of the cell is greater than or equal to a first splitting threshold, or when the number of currently accessed user equipments of the cell is greater than or equal to a second splitting threshold, or when the cell of the cell is When the coverage is less than or equal to the third splitting threshold, the cell is split into at least two sectors, where the current load of the cell is the proportion of PDCH resources occupied by the currently accessed user equipment in the available PDCH resources of the cell, The cell coverage of the cell is a level value of the cell in the measurement report reported by the user equipment, and then allocates available PDCH resources to each physical carrier included in the first sector where the first user equipment is located, the first fan The area is any one of the at least two sectors.

It is to be noted that before the cell is split into at least two sectors, a split plan of the cell may be formulated according to the number of user equipments accessed by the cell and the distribution of the user equipment, where the split plan includes the cell The physical carrier is allocated to at least two of the sectors, and the PDCH resources occupied by the first user equipment may be adjusted according to the splitting plan, so as to avoid resource conflicts when performing cell splitting.

The processor 1002 is specifically configured to split the cell into at least two sectors by using a space division plus orthogonal training sequence technique. The space division plus orthogonal training sequence technology refers to allocating user equipments in different sectors, spatially isolating, and passing different user equipments or TBFs on two physical carriers of different sectors and the same frequency point. Different TSCs are allocated so that the base station can identify the uplink data of different user equipments, and the terminal can identify its own downlink data. Therefore, the cell is split by the space division plus orthogonal training sequence technology, so that better interference isolation is formed between the logical carriers of the at least two sectors obtained after the splitting. Different user equipments or TBFs on two physical carriers of different sectors and the same frequency point can use the same USF or the same TFI. The two different TSCs assigned are as theoretically orthogonal or nearly orthogonal to achieve the best performance.

In particular, if the time slot of the PDCH of the physical carrier after the splitting is consistent with the time slot of the PDCH of the logical carrier corresponding to the splitting in the process of cell splitting, the processor 1002 may transmit data in the first user equipment. If the data volume is greater than the preset capacity threshold, the logic of the at least two sectors is determined when the data volume is greater than the preset capacity threshold. Obtaining the first resource that is not occupied in the carrier And being allocated to the first user equipment again, where the first resource is the same as the identifier of the second resource occupied by the first user equipment before the re-allocation, and the first resource and the logical resource where the second resource is located The parameter configuration is the same.

Optionally, when the load in the cell is greater than the preset load threshold, the processor 1002 may perform dynamic channel switching. The dynamic channel switching refers to configuring the cell logical carrier to be a TCH (Traffic Channel). One of the time slots is converted into a PDCH. When the load in the cell is less than or equal to the preset load threshold, a dynamic channel release can be performed. The dynamic new release refers to configuring one of the time slots of the PDCH to be converted on the logical carrier of the cell. Into TCH.

Further, after the cell is capable of performing cell splitting and splitting the cell into at least two sectors, if the number of user equipments accessed in the cell is small, communication resources of at least two sectors cannot be fully utilized. The processor 1002 is further configured to: when a sector in the sector included in the cell has a sector whose current load is less than or equal to a first merge threshold, or when a sector exists in a sector included in the cell When the current number of access user equipments in the area is less than or equal to the second merge threshold, or when there is a sector in the sector included in the cell that has a cell coverage greater than or equal to the third merge threshold, Acquiring at least two sectors in the included sector, the at least two sectors including at least one of the sectors satisfying the merge condition, wherein the current load of the sector is currently in the available PDCH resources of the sector The proportion of the available PDCH resources occupied by the user equipment, the cell coverage of the sector is the level value of the sector in the measurement report reported by the user equipment, and then the at least the Two sectors are merged.

The resource management device provided by the embodiment of the present invention manages the cell PDCH resource according to the sector, so that each physical carrier occupies a reasonable communication resource, and when the cell is determined to be small When the area is split, the cell is split to obtain at least two sectors, and the parameter configuration of the logical carrier existing in each sector is the same as the parameter configuration of the logical carrier existing in the pre-split cell, so that the available communication resources of the cell are increased by at least Double, and when the sector satisfies the merge condition, at least two sectors are merged, which saves communication resources, and therefore, the flexibility of the resource allocation manner is improved compared to the prior art.
