Description

Inter-cell resource allocation device, device and method

Technology"|^^ domain

The present invention relates to the field of communications technologies, and in particular, to an inter-cell resource allocation apparatus, device, and method. Background technique

With the continuous development of mobile networks, traditional network indicators such as handover/access success rate cannot fully represent the performance of wireless networks, and the user experience is increasingly concerned by operators and wireless users.

In the existing network, due to the mobility of the user and the uneven distribution of the users, the traffic of different sectors is not balanced, and in the existing network, the resource allocation of each sector of each station under the same cluster is generally the same. As a result, the sector user experience with poor traffic is poor, and the network resources of the cell with small traffic are not used up, the performance of the whole network is not optimal, and the user experience is not good enough. FIG. 1 is a schematic diagram of traffic distribution of different cells in the same site in the three-sector form of the traditional networking mode as shown in FIG. 1 , and the traffic is unbalanced between different cells (different carriers or different intra-frequency cells) of the same site under three sectors of the traditional networking mode. The problem of unreasonable resource allocation has caused problems in resource usage imbalance and user experience differences under the same site. Statistics YN Bureau Under the Radio Network Controller (RNC), the unbalanced traffic between cells in the same site accounts for more than 30% of the entire network.

In addition, even in the scenario where the traffic distribution of each cell is balanced, since most of the services initiated by the user are small packet burst services, the traffic is not balanced in the instantaneous short period statistics, for example, both cells are It is 5 users. In the first short-term period, for example, 2ms, there may be three users in the cell 1 and the cell 2 to initiate the packet service, but in the next short period, only one user in the cell may still initiate the service, but the cell Second, there are 4 users to initiate the packet service. At this time, the actual traffic is also unbalanced, and the user experience of the two cells is also different.

In the current wireless network, when the operator has the capacity expansion requirement and there is no extra frequency, the schematic diagram of the split antenna shown in Figure 2, the split antenna, the active antenna system (AAS) and other technologies will be the uplink and downlink beams ( DL/UL Beam) are both split (vertical or horizontal) and configured as different logical cells (Outer Cell and Inner Cell). The two cells are co-frequency, forming sector splitting, code resource and power resource phase gain. However, as shown in the traffic distribution diagram of the split cell shown in FIG. 3, the traffic of the current network is unevenly distributed. - The high-speed downlink packet access (HSDPA) data transmission of the two cells in the two cells is generally different. The power of the cell with large power demand may be insufficient, and the power of the cell with small power demand remains. The use of small-area power is unbalanced, and the difference in user experience is large.

In summary, it is necessary to provide a solution that reduces the difference in user experience and improves the user experience. Summary of the invention

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, instead of All embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

FIG. 4 is a schematic structural diagram of an inter-cell resource allocation apparatus according to an embodiment of the present invention. The apparatus 1000 includes:

The first obtaining unit 11 is configured to acquire a user-aware parameter demand value of at least two cells in a current resource allocation period.

Since the traffic between cells is not balanced, the resources between cells need to be optimally allocated. The cell may be an intra-frequency or inter-frequency cell. For existing simple load-based power allocation schemes, such as inter-carrier power allocation, R99-H power allocation and GU power allocation, etc., all allocate power of inter-frequency cells, and do not involve resource allocation of intra-frequency cells formed by, for example, splitting antennas. These allocation schemes are all based on inter-carrier cells.

This embodiment is not based on load-based resource allocation, but is based on cell user perception for resource allocation. The first obtaining unit 11 acquires a user-aware parameter demand value of at least two cells in the current resource allocation period. The at least two cells may be inter-sector or inter-carrier cells. The user-aware parameters may include: user data transmission power, user throughput rate, user number transmission delay, user priority, number of users, user access delay, user service type, user data volume, channel quality, etc. Reflecting the perception of community users brought about by resource allocation.

As an implementation manner, the first obtaining unit 11 may be specifically configured to: acquire, in a current resource allocation period, a user-aware parameter demand value of at least two cells in the current resource allocation period in real time.

Real-time acquisition of user-aware parameter demand values can avoid false positives caused by historical value prediction schemes.

As another implementation manner, the first acquiring unit may be specifically configured to: acquire, according to a user-aware parameter historical value of at least two cells in a previous resource allocation period, a user of the at least two cells in the current resource allocation period. Perceived parameter demand value. A detailed description of this embodiment can be found in the following embodiments.

The determining unit 12 is configured to determine a resource allocation policy in the current resource allocation period according to a user-aware parameter demand value of at least two cells in the current resource allocation period.

After the first obtaining unit 11 obtains the user-aware parameter demand value, the determining unit 12 may determine how to perform resource allocation according to the user-aware parameter demand value, that is, determine a resource allocation policy in the current resource allocation period. The one-to-one allocation unit 13 is configured to perform resource allocation in the at least two cells according to a resource allocation policy in the current resource allocation period.

The allocating unit 13 performs resource allocation among the cells according to the resource allocation policy within the current resource allocation period determined by the determining unit 12. Since resource allocation is directly based on cell user perception, it is possible to reduce the difference in user perception.

An inter-cell resource allocation apparatus according to an embodiment of the present invention can determine a resource allocation policy between cells according to a perceptual parameter demand value of a cell user, and perform resource allocation, thereby reducing the difference in user experience between the regions and improving the user experience. FIG. 5 is a schematic structural diagram of another inter-cell resource allocation apparatus according to an embodiment of the present invention. The apparatus 2000 includes:

The second obtaining unit 21 is configured to obtain a user-perceived parameter historical value of the at least two cells in the previous resource allocation period before the resource allocation between the at least two cells is performed in the current resource allocation period.

Before the inter-cell resource allocation is performed in the current resource allocation period, the second acquiring unit 21 acquires the historical value of the user parameter of the cell user in the previous resource allocation period, where one cell may include multiple users, and one cell corresponds to one user-perceived parameter historical value. . The user-aware parameters include: user number transmission power, user throughput rate, user number transmission delay, user priority, number of users, user access delay, user service type, user data volume, channel quality, and the like.

The first obtaining unit 22 is configured to obtain, according to the user-aware parameter historical value of the at least two cells in the previous resource allocation period, the user-sensed parameter demand value of the at least two cells in the current resource allocation period.

Since the resource requirement of the cell user is stable in a certain time range, the resource requirement reflected by the user's perceptual parameter requirement is also relatively stable. Therefore, the first obtaining unit 22 is based on the historical value of the cell user user perceptual parameter in the previous resource allocation period. The cell user user perceived parameter demand value in the current resource allocation period may be determined to some extent more accurately.

The determining unit 23 is configured to determine, according to a user-aware parameter demand value of the at least two cells in the current resource allocation period, a resource allocation policy in the current resource allocation period.

After the first obtaining unit 22 acquires the user-aware parameter demand value, the determining unit 23 may determine how to perform resource allocation according to the user-perceived parameter demand value, that is, determine the current resource allocation period. - - Source allocation policy.

The allocating unit 24 is configured to perform resource allocation in the at least two cells according to the resource allocation policy in the current resource allocation period.

The allocating unit 24 performs resource allocation among the cells according to the resource allocation policy within the current resource allocation period determined by the determining unit 23. Since resource allocation is directly based on cell user perception, it is possible to reduce the difference in user perception.

An inter-cell resource allocation apparatus according to an embodiment of the present invention, by determining a current cell user perceptual parameter demand value according to a cell user perceptual parameter historical value, thereby determining a resource allocation policy, performing resource allocation, and reducing the interval The user feels the difference and improves the user experience; and the historical value prediction scheme does not have the requirement for real-time data collection, so the device processor resources are less occupied. FIG. 6 is a schematic diagram showing another structure of an inter-cell resource allocation apparatus according to an embodiment of the present invention. The apparatus 3000 includes:

The second obtaining unit 31 is configured to obtain a user-aware parameter historical value of the at least two cells in the previous resource allocation period before the resource allocation between the at least two cells is performed in the current resource allocation period.

Before performing the inter-cell resource allocation in the current resource allocation period, the second obtaining unit 31 acquires the historical value of the user parameter of the user of the user in the previous resource allocation period, where one cell may include multiple users, and one cell corresponds to one user-perceived parameter historical value. . The user-aware parameters include: user number transmission power, user throughput rate, user number transmission delay, user priority, number of users, user access delay, user service type, user data volume, channel quality, and the like.

The third obtaining unit 32 is configured to obtain a comparison result between the user-aware parameter history value and the set parameter value.

In this embodiment, the obtained cell user perceptual parameter historical value in the previous resource allocation period is compared with the set parameter value to obtain a comparison result of each cell, and the set parameter value may be an average value of resource allocation or Custom parameter values. By comparing, it is possible for the user to know which cell has more traffic and which cell has less traffic. The user-aware parameters include: user number transmission power, user throughput rate, user number transmission delay, user priority, number of users, and the like. The cell may be a co-frequency or inter-frequency cell. This embodiment uses traffic as an application scenario, but is not limited to this scenario.

The first obtaining unit 33 is configured to acquire, according to the comparison result, the previous resource allocation period - a sharing state of each cell in at least two cells, wherein the sharing state includes sharing in, sharing out, and not sharing.

In a resource pool, resources are shared between cells, and resources are allocated through sharing. For the case where the user-aware parameter historical value is greater than the set parameter value, it can be known that the cell traffic is relatively large, and the user-aware parameter demand value is large. At this time, the cell needs to acquire additional resources from other cells, that is, in the shared input. If the historical value of the user-aware parameter is less than the set parameter value, it can be known that the cell traffic is relatively small, and the user-aware parameter demand value is small. At this time, the cell can share additional resources for other cells, that is, If the user-aware parameter history value is equal to the set parameter value, it can be known that the cell traffic is in an average value, and the historically allocated resource can meet its own needs. In this case, the cell does not need to obtain from another cell. Additional resources, and do not share resources to other cells, that is, in an unshared state.

It should be noted that each cell sharing state may change during each resource allocation period, and is shared during the current period, and may become shared or not shared in the next period.

The determining unit 34 is specifically configured to determine, according to the resource sharing state, a resource sharing policy of each cell in the at least two cells in a current resource allocation period.

The determining unit 34 determines the resource sharing policy of each cell in the current resource allocation period according to the resource sharing state of each cell, that is, the additional resources of the cell sharing the outbound state are shared to the cell in the shared inbound state, and the cell in the unshared state is used. Do not share resources.

The allocating unit 35 is configured to perform resource allocation in the at least two cells according to the resource sharing policy.

The allocating unit 35 performs resource allocation in accordance with the determined resource sharing result. The specific implementation of the inter-cell resource allocation device 3000 is described by taking the power allocation as an example. In this embodiment, the power allocation parameter is used as an example, and the user-aware parameter may be the user's data transmission power, or the user throughput rate, and the user. The data transmission delay, the user priority, the number of users, the user access delay, the user service type, the user data volume, and the channel quality are used as an example. The cell may be a co-frequency or inter-frequency cell.

Taking the Universal Mobile Telecommunications System (UMTS) as an example, if the current power allocation period is the first power allocation period, each transmission time interval (Transmission Time Interval, ΤΉ) is a transport format resource combination (Transport Format and - -

After the resource combination, TFRC), the usage power of each TTI in the current power allocation period is counted, and the next power allocation period is entered. If the current power allocation period is not the first power allocation period, the previous power allocation period is counted. The power usage of each cell is transmitted. Then, the power usage of each cell is compared with the set parameter value to obtain a comparison result. The above description uses UMTS as an example, but the resource allocation device is applicable to various standards.

For the case where the user usage power history value is greater than the set parameter value, it can be known that the cell traffic is relatively large, and the user data transmission power demand value is large. At this time, the cell needs to acquire additional resources from other cells. That is, in the shared-in state; for the case where the user's data transmission power history value is less than the set parameter value, it can be known that the cell traffic is relatively small, and the user's data transmission power demand value is small, and at this time, the cell can give other The cell shares the additional resources, that is, in the shared out state. For the case where the user uses the power history value equal to the set parameter value, it can be known that the cell traffic is in the average value, and the historically allocated resources can meet their own needs. The cell does not need to acquire additional resources from other cells, and does not share resources to other cells, that is, in a non-shared state; if several cells are in a shared-in state or a shared-out state at the same time, each cell in the current period The shared state also becomes unshared and is used to indicate resource allocation starting this week.

Determining the shared state of the power allocation of each cell and requesting the shared power, the shared power of the request includes the shared power and the shared power, and the shared power, that is, the cell sharing the inbound state requests the power shared from another cell, and the shared power is shared. The outbound cell requests power shared to other cells.

According to the sharing state of each cell and the requested sharing power, the resource sharing result in the current power allocation period, that is, which cells do not share power, and the ratio of requesting shared power or requesting shared power to the maximum transmitting power are determined. The requested shared output power is placed in the power pool, and the power is shared to the cell that requests the sharing.

The shared power recovered in the power pool is distributed in proportion to the power.

This embodiment can be applied to a cell scenario in which the traffic volume between cells is unbalanced, such as between multiple intra-frequency cells and between cells of multiple sectors in the same site.

Regarding inter-sector power sharing, a cellular mobile communication base station transmits and receives signals in a plurality of sectors in many cases. Generally, the coverage of one base station can be divided into three sectors and six sectors. The base station's transmit channel has a power amplifier at the end to amplify the signal. The cells involved in the power sharing scheme need to be on the same power amplifier. - - In the prior art, in the case of sector division, the signal of each sector is amplified by a power amplifier and transmitted through a directional antenna. The signal for each sector is amplified by a power amplifier. Disadvantages of this approach:

1. If a power amplifier is damaged or other parts of the channel are faulty, the transmission signal of one sector may be interrupted, which seriously affects the reliability of the entire base station system;

2. When the number of calls in each sector is unbalanced, the use of the power amplifier is also unbalanced. The efficiency of using a power amplifier may be low, and system resources are wasted;

3. The output power requirement of a single power amplifier is high, and the power amplifier cost is high;

4. The cells involved in the power sharing scheme need to be on the same power amplifier, and the cells on different power amplifiers cannot be shared.

In this embodiment, the power Trunking mode is used:

Add a hybrid bridge matrix in front of and behind the amplifier. The hybrid bridge matrix 1 in front of the power amplifier divides the signal of each sector into the input ports of all the power amplifiers, that is, the signals of any one sector are amplified by all the power amplifiers; the hybrid bridge matrix 2 behind the power amplifier passes phase cancellation, The signal of each sector appears only at a specific output port, and the power of other output ports is extremely small.

In this mode, cells on different power amplifiers can also be shared because they are in the same power resource pool.

After the resource sharing in the embodiment of the present invention, more resources can be used, thereby improving user perception, such as reducing user data transmission delay and increasing data transmission rate. An inter-cell resource allocation apparatus according to an embodiment of the present invention, by determining a current cell user perceptual parameter demand value according to a cell user perceptual parameter historical value, thereby determining a resource allocation policy, performing resource allocation, and reducing the interval Users feel the difference and improve the user experience.

Step S101: Acquire a user-aware parameter demand value of at least two cells in a current resource allocation period. - - Because the distribution of inter-cell traffic is not balanced, the resources between cells need to be optimally allocated. The cell can be an intra-frequency or inter-frequency cell. For existing simple load-based power allocation schemes, such as inter-carrier power. Allocation, R99-H power allocation, and GU power allocation, etc., all allocate power of the inter-frequency cell, and do not involve resource allocation of the same-frequency cell formed by, for example, a split antenna. These allocation schemes are all based on inter-carrier cells.

This embodiment is not based on load-based resource allocation, but is based on cell user perception for resource allocation. In this step, the user-aware parameter demand value of at least two cells in the current resource allocation period is obtained. The at least two cells may be inter-sector or inter-carrier cells. The user-aware parameters may include: user data transmission power, user throughput rate, user number transmission delay, user priority, number of users, user access delay, user service type, user data volume, channel quality, etc. Reflecting the perception of community users brought about by resource allocation.

As an implementation manner, step S101 may be specifically: acquiring, in a current resource allocation period, a user-aware parameter demand value of at least two cells in the current resource allocation period in real time.

As another implementation manner, step S101 may be further configured to: obtain user perceptual parameters of the at least two cells in the current resource allocation period according to user perceptual parameter historical values of at least two cells in a previous resource allocation period. Demand value. A detailed description of this embodiment can be found in the following embodiments.

Step S102: Determine, according to a user perceptual parameter requirement value of at least two cells in the current resource allocation period, a resource allocation policy in the current resource allocation period.

After the user-perceived parameter demand value is obtained in step S101, in this step, the resource allocation may be determined according to the user-aware parameter demand value, that is, the resource allocation policy in the current resource allocation period is determined.

Step S103: Perform resource allocation in the at least two cells according to the resource allocation policy in the current resource allocation period.

In this step, resource allocation is performed between cells according to the determined resource allocation policy in the current resource allocation period. Since resource allocation is directly based on cell user perception, it is possible to reduce the difference in user perception.

An inter-cell resource allocation method according to an embodiment of the present invention, according to a cell user - - Sensing parameter demand value, determining resource allocation strategies between cells, and performing resource allocation, which can reduce the difference in user perception and improve user experience. FIG. 9 is a flowchart of another method for resource allocation between cells according to an embodiment of the present invention. The method includes the following steps:

Step S201: Before performing resource allocation between the at least two cells in the current resource allocation period, obtain a user-perceived parameter historical value of the at least two cells in the previous resource allocation period.

Before the inter-cell resource allocation is performed in the current resource allocation period, the historical value of the user parameter of the cell user in the previous resource allocation period is obtained. One cell may include multiple users, and one cell corresponds to a user-perceived parameter historical value. The user-aware parameters include: user number transmission power, user throughput rate, user number transmission delay, user priority, number of users, user access delay, user service type, user data volume, channel quality, and the like.

Step S202: Acquire a user-aware parameter demand value of the at least two cells in the current resource allocation period according to a user-aware parameter historical value of the at least two cells in a previous resource allocation period.

Since the resource requirements of the cell users in a certain time range are relatively stable, the resource requirements reflected by the user's perceptual parameter requirements are relatively stable. Therefore, according to the historical value of the perceptual parameter of the cell user in the previous resource allocation period, the data may be compared to some extent. The cell user user perceived parameter demand value in the current resource allocation period is accurately determined.

Step S203: Determine, according to a user perceptual parameter requirement value of the at least two cells in a current resource allocation period, a resource allocation policy in the current resource allocation period.

After obtaining the user-aware parameter demand value, the resource allocation policy may be determined according to the user-aware parameter demand value, that is, the resource allocation policy in the current resource allocation period is determined.

Step S204: Perform resource allocation in the at least two cells according to the resource allocation policy in the current resource allocation period.

Resource allocation is performed between cells according to the determined resource allocation policy within the current resource allocation period. Since the resource allocation is directly based on the perception of the cell user, the difference in the user experience of the interval can be reduced.

According to an embodiment of the present invention, an inter-cell resource allocation method is configured to determine a current cell user perceptual parameter demand value according to a cell user perceptual parameter historical value, thereby determining a resource allocation. - - Strategy, resource allocation, can reduce the difference in user perception and improve user experience; and the historical value prediction scheme does not require real-time data collection, so the device processor resources are less occupied. FIG. 10 is a flowchart of still another method for resource allocation between cells according to an embodiment of the present invention. The method includes the following steps:

Step S301: Before performing resource allocation between the at least two cells in the current resource allocation period, obtain a user-perceived parameter historical value of the at least two cells in the previous resource allocation period.

Step S302: Acquire a comparison result between the historical value of the user-aware parameter and the value of the set parameter.

In this embodiment, the obtained cell user perceptual parameter historical value in the previous resource allocation period is compared with the set parameter value to obtain a comparison result of each cell, and the set parameter value may be an average value of resource allocation or Custom parameter values. By comparing, it is possible for the user to know which cell traffic is more and which cell traffic is less. The user-aware parameters include: user number transmission power, user throughput rate, user number transmission delay, user priority, number of users, and the like. The cell may be a co-frequency or inter-frequency cell. This embodiment uses traffic as an application scenario, but is not limited to this scenario.

Step S303: Acquire, according to the comparison result, a sharing state of each cell in the at least two cells in a previous resource allocation period, where the sharing state includes sharing in, sharing out, and not sharing.

In a resource pool, resources are shared between cells, and resources are allocated through sharing. For the case where the user-aware parameter historical value is greater than the set parameter value, it can be known that the cell traffic is relatively large, and the user-aware parameter demand value is large. At this time, the cell needs to acquire additional resources from other cells, that is, in the shared input. If the historical value of the user-aware parameter is less than the set parameter value, it can be known that the cell traffic is relatively small, and the user-aware parameter demand value is small. At this time, the cell can share additional resources for other cells, that is, If the user-aware parameter history value is equal to the set parameter value, it can be known that the cell traffic is in an average value, and the historically allocated resource can meet its own needs. In this case, the cell does not need to obtain from another cell. Additional resources, no resources to share - - The cell is in an unshared state.

Step S304: Determine, according to the resource sharing state, a resource sharing policy of each cell in the at least two cells in the current resource allocation period.

According to the resource sharing state of each cell, the resource sharing policy of each cell in the current resource allocation period is determined, that is, the additional resources of the cell sharing the outbound state are shared to the cell in the shared inbound state, and the cells in the non-shared state do not share the resource. .

Step S305: Perform resource allocation in the at least two cells according to the resource sharing policy. The resource allocation is performed according to the determined resource sharing result.

According to an embodiment of the present invention, an inter-cell resource allocation method is configured to determine a current cell user perceptual parameter demand value according to a cell user perceptual parameter historical value, thereby determining a resource allocation policy, and performing resource allocation, which may reduce the interval. The user feels the difference and improves the user experience; and the historical value prediction scheme does not have the requirement for real-time data collection, so the device processor resources are less occupied.
