And, the management of radio resources may be in a centralized form in which an entity, such as a mobile switching center (MSC), manages radio resources of individual base stations connected thereto, but this has a disadvantage in that it is very complicated to implement. In a wireless network, the individual base stations are mainly in a distributed form in which corresponding radio resources are managed.

In this regard, according to the related art, a base station (BS) is an 'Available DL Radio Resources' and an 'Available UL Radio Resources' in order for a mobile station (MS) in a cell to efficiently utilize radio resources. 'Informed the available radio resources to the terminal through the parameter. Here, 'Available DL Radio Resources' is a parameter indicating an average ratio of unallocated downlink radio resources with respect to all available downlink radio resources, and 'Available UL Radio Resources' is all available. A parameter indicating an average ratio of unallocated uplink radio resources to uplink radio resources (see Table 1).

[Table 1] Available DL / UL Radio Resources

The UE may determine suitability of the downlink channel and the uplink channel before attempting initial ranging or handover ranging with reference to the parameters.

However, in the prior art, since the determination of channel suitability is determined only by the terminal and ranging is performed, the base station cannot determine and control whether the terminal uses radio resources in advance. Therefore, the base station passively performs Call Admission Control (CAC), Load Control (LC), etc. according to the ranging of the UE, and in this case, the UE may unexpectedly unexpected call denial or There was a problem of being subjected to a handover drop. As a result, the parameter is less useful as a parameter for radio resource management.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an apparatus and method for transmitting overload indication information of a base station, which enables a base station to efficiently perform radio resource management in cooperation with a terminal. .

Another object of the present invention is to provide an apparatus and method for transmitting overload indication information of a base station capable of actively designating an operation of a terminal according to a load state of a base station and actively performing call admission control and load control.

Another object of the present invention is to reduce the amount of data transmitted while maintaining compatibility with existing systems by transmitting overload indication information of the serving base station and the neighboring base station using a downlink channel descriptor (DCD) message and a neighbor advertisement (MOB_NBR_ADV). The present invention provides an apparatus and method for transmitting base station overload indication information.

Another object of the present invention is to check the base station overload indication information transmitted from the base station, when the serving base station and / or the neighboring base station is in an overloaded state, the base station overload indication information to perform a predetermined operation according to the current state of the terminal It is to provide a processing apparatus and method.

And the base station overload indication information processing apparatus in the wireless communication system of one embodiment of the present invention includes a message receiving unit that receives a message including serving base station overload indication information or neighbor base station overload indication information; A message determination unit analyzing the received message to determine a message type, and reading serving base station overload indication information or neighbor base station overload indication information based on the message type; A state checking unit which checks the current state of the terminal and generates terminal state information; And an operation controller for controlling an operation of the terminal for the corresponding base station based on the terminal state information transmitted from the state checking unit, the serving base station overload indication information or the neighbor base station overload indication information transmitted from the message determining unit. Characterized in that.

On the other hand, in a wireless communication system of one embodiment of the present invention, a method for transmitting base station overload indication information includes: checking a load state of at least one of a serving base station and an adjacent base station; Generating overload indication information in a type length value (TLV) format or a bit format based on the load state; Generating a message including the overload indication information in the TLV format or bit format; And transmitting the generated message.

Further, according to the present invention, the terminal reads base station overload indication information to predict call rejection or handover drop for the base station, thereby preventing unnecessary initial ranging or handover ranging, and effectively utilizing radio resources. Has the effect.

In addition, according to the present invention, it is possible to efficiently perform call admission control, load control, and the like with the minimum data transmission amount (1 bit) by using the base station overload indication information in the bit format.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and preferred embodiments. For reference, detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted in the following description.

1 is a block diagram of a base station overload indication information transmission apparatus according to a first embodiment of the present invention. For reference, the apparatus for transmitting the base station overload indication information according to the present invention may be implemented as the base station itself or as part of the base station.

As shown, the base station overload display information transmission apparatus 100 according to the present invention includes a status check unit 110, information collecting unit 120, operation setting unit 130, message generating unit 140, message transmitting unit 150 and the like.

First, the state checking unit 110 generates the serving base station state information by checking the load state or the air-link state of the corresponding base station (that is, the serving base station). The serving base station state information may be displayed as a numerical value corresponding to the load state of the serving base station using a plurality of bits (see Table 1), or may be displayed in one of a plurality of preset modes. Of course, the serving base station state information may be indicated by whether the serving base station is overloaded using one bit. In this case, whether the serving base station is overloaded may be determined by comparing the load state of the serving base station with a preset reference level. Accordingly, the serving base station state information is '1' when the load state of the serving base station is greater than or equal to the reference level. If set to and less than the reference level may be set to '0'. The serving base station state information thus generated is transmitted to the operation setting unit 130.

The operation setting unit 130 generates serving base station overload indication information based on the serving base station state information transmitted from the state confirming unit 110. The serving base station overload indication information may be generated to indicate whether the serving base station is overloaded by simply using one bit (see the second embodiment, which will be described later), and the operation of the terminal according to the load state of the serving base station. This can be generated to be specifically specified.

Table 2 below illustrates that the BS overload indicator information is configured to designate or recommend a specific operation that the UE can take.

[Table 2] BS Overload Indicator in TLV format

In detail, the base station overload indication information composed of 1 byte indicates the selectable operation of the terminal for the corresponding base station for each bit. If set, it informs the following.

First, bit # 0 indicates difficulty in initial network entry to the base station, and bit # 1 indicates that the downlink radio resource of the base station is overloaded, but is in the MOB_BSHO_REQ (BS Handover Request) message or the MOB_BSHO_RSP (BS Handover Response) message. A handover to a target base station not included does not need to be attempted, bit # 2 indicates that the uplink radio resource of the base station is overloaded, but handover to a target base station not included in the MOB_BSHO_REQ message or MOB_BSHO_RSP message. Indicates that there is no need to try. In addition, bit # 3 indicates difficulty in handover to the base station, bit # 4 indicates difficulty in associating with the base station, and bit # 5 indicates scanning of the base station. Indicates that there is no need. In addition, bit # 6 indicates difficulty in creating a service flow for a corresponding base station, and bit # 7 indicates difficulty in activating a service flow for a corresponding base station.

Meanwhile, the message generator 140 receives the serving base station overload indication information from the operation setting unit 130 and generates a message for transmitting it to the terminal. Although a separate dedicated message may be used as a message for transmitting the serving base station overload indication information, it is preferable to use an existing MAC (Media Access Control) management message to reduce the amount of data transmitted. In the present embodiment, the serving base station overload indication information is transmitted using a downlink channel descriptor (DDC) message among MAC management messages.

Table 3 below illustrates the structure of the DCD message used in the present invention.

Referring to Table 3, a DCD message according to the present invention includes a mandatory area such as a MAC management message type, a configuration change counter, and a type length value (TLV) encoded. It includes a TTL Encoded information area. Serving base station overload indication information (see Table 2) is included in the TLV encoded information area in the TLV format.

[Table 3] DCD message format

Finally, the message transmitter 150 transmits a DCD message including the serving base station overload indication information generated by the message generator 140 to the terminal.

Meanwhile, a method of transmitting serving base station overload indication information has been described so far. Hereinafter, a method of transmitting neighbor base station overload indication information will be described.

Referring to FIG. 1, the information collecting unit 120 receives a DCD message transmitted from a neighbor base station through a network interface. Similarly, the DCD message of the neighboring base station includes the overload indication information of the neighboring base station (see Table 2), and the information collecting unit 120 reads the neighbor BS ID and the neighbor base station overload indication information. To the operation setting unit 130.

Then, the operation setting unit 130 compares the neighbor base station overload indication information transmitted from the information collection unit 120 with the serving base station overload indication information, and if the comparison result is different, the neighbor base station ID and the neighbor base station overload indication information are different. The message generator 140 transmits the message. Of course, the operation setting unit 130 may be implemented to transmit the neighbor base station ID and the neighbor base station overload indication information to the message generator 140 without the comparison process, and as an alternative, the information collector 120 may directly transmit the neighbor base station. The ID and neighbor BS overload indication information may be transmitted to the message generator 140.

The message generator 140 receives the neighbor base station ID and the neighbor base station overload indication information from the operation setting unit (or the information collector) and generates a message for transmitting the neighbor base station overload indication information to the terminal. It is preferable to use an existing MAC (Media Access Control) management message as a message for transmitting the neighbor base station overload indication information. In particular, the present embodiment uses a MOB_NBR_ADV (Neighbor Advertisement) message.

Table 4 below illustrates the structure of the MOB_NBR_ADV message used in the present invention.

[Table 4] MOB_NBR_ADV message format

Referring to Table 4, the MOB_NBR_ADV message according to the present invention includes a neighbor base station ID and corresponding neighbor base station overload indication information. If there are a plurality of neighbor base stations, the corresponding information is included in a repetitive pattern. Here, the neighbor BS overload indication information is included in the TLV Encoded Neighbor information area of the MOB_NBR_ADV message in the TLV format illustrated in Table 2, and preferably in the TLV encoded information area of the MOB_NBR_ADV message as the DCD_settings parameter. Included. The DCD_settings parameter is a TLV value implying a DCD message of a neighbor base station, and the DCD_settings field includes only DCD TLV values of a neighbor base station different from the serving base station.

Finally, the message transmitter 150 transmits the MOB_NBR_ADV message including the neighbor base station overload indication information generated by the message generator 140 to the terminal.

Hereinafter, an apparatus for transmitting base station overload indication information according to a second embodiment of the present invention will be described with reference to FIG. 2. For reference, unlike the first embodiment using the TLV format, the second embodiment of the present invention uses the bit format to reduce the amount of data to be transmitted to the terminal.

As shown in FIG. 2, the base station overload indication information transmitting apparatus 200 according to the second embodiment of the present invention includes a status checker 210, an information collector 220, a message generator 240, and a message. A transmitter 250 and the like.

The state checking unit 210 determines whether the overload is performed by checking the load state of the serving base station, and generates and transmits the serving base station overload indication information in a bit format to the message generator 240. Here, the determination of whether the serving base station is overloaded may be performed by comparing the load state of the serving base station with a preset reference level, as described above. It may be set to '0' if less than the reference level.

The information collecting unit 220 receives a DCD message transmitted from a neighbor base station through a network interface or the like, and transmits a neighbor BS ID and neighbor base station overload indication information to the message generator 240.

The message generator 240 receives the serving base station overload indication information and / or the neighbor base station overload indication information from the status checker 210 and / or the information collector 220 and generates a message for transmitting the same to the terminal. do.

Preferably, the message for transmitting the serving base station overload indication information uses a DCD (Downlink Channel Descriptor) message. It includes. Meanwhile, the message for transmitting the neighbor base station overload indication information may preferably use a MOB_NBR_ADV (Neighbor Advertisement) message. Similarly, the MOB_NBR_ADV message according to the present invention may overload a corresponding base station at a predetermined position associated with each neighbor base station ID. Each field of 1 bit length for display information is included.

The message transmitter 250 may transmit a DCD message (including serving base station overload indication information) and / or a MOB_NBR_ADV message (including at least one neighbor base station overload indication information) generated by the message generator 240 to the terminal. Send.

Meanwhile, the terminal receives the serving base station overload indication information and / or the neighbor base station overload indication information and performs an appropriate operation according to the current state of the terminal, which will be described in detail below.

3 is a block diagram of a base station overload indication information processing apparatus according to the present invention. For reference, the base station overload indication information processing apparatus according to the present invention may be implemented as the terminal itself or as part of the terminal.

As shown, the base station overload display information processing apparatus 300 according to the present invention is a message receiving unit 310, message determining unit 320, status check unit 330, operation control unit 340, operation performing unit ( 350), and the like.

The message receiver 310 receives a message including the serving base station overload indication information and / or the neighbor base station overload indication information transmitted from the base station and transmits the message to the message determiner 320.

Then, the message determiner 320 analyzes the message transmitted from the message receiver 310 to read the type of message and the base station overload indication information included in the message.

Specifically, the message determining unit 320 reads the MAC Management Message Type included in the message transmitted through the message receiving unit 310 to determine whether the corresponding message is a DCD message (Management Message Type = 1). It is determined whether the message is MOB_NBR_ADV (Management Message Type = 53). In the case of the DCD message, the serving base station overload indication information included in the corresponding message is read. In the case of the MOB_NBR_ADV message, the neighbor base station ID (Neighbor BSID) and the neighbor base station overload indication information are read. 340).

The state checking unit 330 checks the current state of the terminal and transmits terminal state information to the operation control unit 340. The state of the terminal may include an activation state, a sleep state, an idle state, a network initial entry state, a network re-entry state, a network entry completion state, a hand. Examples include an over state, an association state, and a scanning state. The terminal state information may be generated by setting a possible combination of these states to a plurality of modes.

The operation control unit 340 is configured for the base station based on the terminal state information transmitted from the status checker 330, the serving base station overload indication information and / or the neighbor base station overload indication information transmitted from the message determination unit 320. Control the specific operation of the terminal. In this case, it is assumed that the serving base station and the overload information are the same with respect to the adjacent base station without the overload information, and the specific operation of the terminal is controlled.

Referring to the above-described first and second embodiments, the serving base station overload indication information and / or the adjacent base station overload indication information is in a TLV format or a bit format, and the operation control unit 340 controls the base station overload indication information. The operation of the terminal is controlled in different ways according to the format of the.

First, when the base station overload indication information is in the TLV format, since the selectable operation of the terminal for the corresponding base station is set, the operation control unit 340 refers to the selectable operating range of the terminal set for each bit of the terminal. Control to perform the proper operation according to the current state.

On the other hand, when the base station overload indication information is a bit format, it can only know whether the base station is overloaded, the operation control unit 340 refers to whether the serving base station and / or neighboring base station is overloaded to determine the current state of the terminal. Therefore, control to perform a preset operation.

In this regard, the operation of the terminal according to the preferred embodiment of the present invention may be set as follows.

First, when the overload indication information of the corresponding base station (serving base station / adjacent base station) is set to '0', this means that the base station is in a normal operating state, and thus the terminal may try all selectable operations for the base station. .

Second, when the serving base station overload indication information included in the DCD message is set to '1', this means that the serving base station is in an overloaded state, and thus the UE operates as follows according to the current state.

Mode 1: If the terminal is in a state of performing initial network entry for the base station, the terminal stops all operations for the base station and attempts to enter the network for another base station.

Mode 2: If the terminal is in the idle state to perform network reentry, the terminal stops all operations for the base station and attempts to reenter the network to another base station or returns to the idle state.

Mode 3: If the UE performs network reentry during handover, the UE stops all operations for the corresponding base station (target base station) and attempts to handover to another suitable base station or cancels the handover.

Mode 4: If the terminal completes network entry for the base station (serving base station), the terminal receives a handover request from the base station and attempts to handover to a neighbor base station not in an overloaded state.

Mode 5: If the terminal is in the idle state, the terminal does not attempt to re-enter the network.

Third, when the neighbor BS overload indication information included in the MOB_NBR_ADV message is set to '1', this means that the neighbor BS is overloaded, and thus the UE operates as follows.

First, the terminal does not request handover to the neighboring base station from the serving base station, and also ignores the handover request to the neighboring base station transmitted from the serving base station. Furthermore, the terminal does not attempt association with the neighbor base station or scanning of the neighbor base station.

Fourth, when the serving base station overload indication information and all neighbor base station overload indication information are both set to '1', this means that the serving base station and neighboring neighbor base stations are all overloaded, and thus, the terminal performs all operations on the serving base station. Stop and return to the initialization state. The terminal then attempts to acquire a downlink channel by scanning. At this time, if the base station overload indication information is found to the base station '0', the terminal attempts to initially enter the network for the base station, otherwise it continues to scan for downlink channel acquisition.

Meanwhile, the operation execution unit 350 includes a network entry execution unit 351, a handover execution unit 352, a scanning execution unit 353, an association execution unit 354, and the like to control the operation control unit 340. Accordingly perform the corresponding operation.

Hereinafter, a method of transmitting base station overload indication information according to the present invention will be described with reference to FIGS. 4 to 6. For reference, a detailed process or operation principle of the method for transmitting the base station overload indication information according to the present invention may refer to the description of the apparatus for transmitting the base station overload indication information.

4 is a flowchart of a method for transmitting base station overload indication information according to a first embodiment of the present invention. For reference, the present embodiment is a case where the serving base station overload indication information is transmitted using a DCD message.

The format of the serving base station overload indication information is determined in consideration of the basic capability of the terminal, the necessity of setting an operation for the terminal, system compatibility, and the like (S420). In the present embodiment, the format of the serving base station overload indication information may be selected between the TLV format and the bit format, and of course, other types of formats may be selected. For reference, the step S420 is a necessary step in a system supporting both the TLV format and the bit format. If the format of the base station overload indication information is specified by a standard, the step S420 may be omitted.

If the serving base station overload indication information is determined in the TLV format in step S420, the base station sets the selectable specific operation of the terminal based on its load state and then generates the serving base station overload indication information in the TLV format. (S430). The base station generates a DCD message including the serving base station overload indication information in the TLV format (S440). In this case, since the foregoing description may be referred to the serving base station overload indication information in the TLV format and the structure of the DCD message including the same, description thereof is omitted.

If the serving base station overload indication information is determined as the bit format in step S420, the base station generates the serving base station overload indication information of the bit format indicating whether the serving base station is overloaded (S450). The base station generates a DCD message including the serving base station overload indication information of the bit format in a predetermined position (S460).

Finally, the base station transmits the DCD message including the serving base station overload indication information of the TLV format or bit format generated in this way to the terminal (S470).

5 is a flowchart of a method for transmitting base station overload indication information according to a second embodiment of the present invention. For reference, the present embodiment is a case where neighbor base station overload indication information is transmitted using a MOB_NBR_ADV message.

In detail, first, the base station (serving base station) receives the DCD message of the adjacent base station through the network interface (S510). The serving base station analyzes the DCD message of the neighbor base station to read the neighbor base station overload indication information and confirms the format (S520). Here, step S520 is a necessary step in a system supporting both the TLV format and the bit format. Similarly, when the format of the base station overload indication information is specified by a standard, the step S520 may be omitted.

If the neighbor base station overload indication information is confirmed in the TLV format in step S520, the serving base station generates a MOB_NBR_ADV message including the neighbor base station overload indication information of the TLV format (S530). In this case, since the foregoing description may be referred to the neighbor BS overload indication information in the TLV format and the structure of the MOB_NBR_ADV message including the same, description thereof will be omitted.

If the neighbor base station overload indication information is confirmed in bit format in step S520, the serving base station generates a MOB_NBR_ADV message in which the neighbor base station overload indication information of the bit format is included in a predetermined position (S540).

Finally, the serving base station transmits the MOB_NBR_ADV message including the neighbor base station overload indication information of the TLV format or bit format generated as described above (S550).

Hereinafter, with reference to FIG. 6, a method for receiving and processing base station overload indication information transmitted as described above will be described.

The terminal receives a message including serving base station overload indication information and / or neighboring base station overload indication information transmitted from a base station (serving base station) (S610). The message is analyzed to read the type of the message and the base station overload indication information included in the message (S620). Specifically, the MAC management message type included in the received message is read to determine whether the corresponding message is a DCD message or a MOB_NBR_ADV message. In the case of the DCD message, the serving base station overload indication information included in the message is read. In the case of the MOB_NBR_ADV message, the neighbor base station ID (Neighbor BSID) and the neighbor base station overload indication information are read.

Thereafter, the terminal checks whether the format of the base station (serving base station / adjacent base station) overload indication information is a TLV format or a bit format (S630). If the base station overload indication information is in the TLV format, the terminal performs a specific operation according to the current state of the terminal with reference to the selectable operating range of the terminal set for each corresponding base station (S640). On the contrary, when the base station overload indication information is in a bit format, the terminal performs a preset operation according to the current state of the terminal with reference to whether the corresponding base station is overloaded (S650). For reference, the step S630 may be omitted when the format of the base station overload indication information is specified by a standard, etc. For details of the specific operation of the terminal may refer to the above-described content related to FIG. 3. In addition, the neighboring base station without the overload information assumes that the serving base station and the overload information are the same and performs an operation.
