Description

The present invention claims to be submitted to the Chinese Patent Office on March 29, 2006, and the application number is 200610073419. 5 , the invention name is "a cell edge radio resource redistribution method" The priority of the Chinese Patent Application, the entire contents of which is incorporated herein by reference.

Technical field

The present invention relates to the field of wireless communication technologies, and in particular, to a method for cell edge radio resource reallocation, a device for processing cell edge radio resource reallocation, and a base station system.

Background technique

In the wireless evolved network, the architecture of the access network part is evolved from a two-node structure of a Node B (B node) and an RNC (Radio Network Controller) of the 3G network to only one node eNode B (Enhanced Node B, Enhanced Node B) single node architecture.

In the research given by the evolution network, the design of RRM (Radio Resource Management) function of the radio access network is an important issue, especially considering the R belly function between eNode B, such as interference management and load. Balance and so on.

At present, the wireless evolution network architecture for this topic is shown in Figure 1. There is no independent wireless support server node in the wireless network architecture to handle inter-cell RRM functions. The small-area RRM functions are distributed in different base stations 101, 102 and 103. An XI interface exists between the base stations 101, 102, and 103 and the access gateway 104, and an X2 interface exists between the adjacent base stations. The base stations 101, 102, and 103 shown in FIG. 1 are adjacent to each other, and the base station 101 and the base station 102 are adjacent to each other. Between the base station 102 and the base station 103, an X2 interface exists between the base station 101 and the base station 103.

In the prior art, a frequency resource allocation scheme between cells is a soft frequency multiplexing method in which a cell is divided into an edge and a center.

As shown in FIG. 2, each cell is divided into a central area 201 (i.e., a hexagonal area formed by a broken line in Fig. 2) and an edge area 202 (i.e., a hexagonal annular area formed by a dotted line and a solid line in Fig. 2). In two parts, the edge area 202 is an area that has signals intersecting with other cells, and the edge area 202 of each cell is statically or semi-statically allocated part of the radio resources, and the allocated radio resources and the edge area 202 of the neighboring cell are The assigned wireless resources are disjoint. In the process of performing service transmission scheduling, the base station first schedules the UE (User Equipment) in the edge area 202, and then schedules the UE in the central area 201. Part of the resource allocation of the cell edge area 202 can vary over a long period of time, Guarantee resource optimization within time. The above solution solves the problem of interference at the edge of the cell, and also provides a better spectrum utilization rate. At the same time, the above technical solution is adopted, and when the edge load of a certain cell is heavy, or the neighboring area interference is considered to be large, the request may be required. Partial radio resources are deactivated in the cell edge area adjacent to the lighter load. For example, the neighboring cell uses the method of reducing power usage or stopping the use to achieve the purpose of deactivating (mu te) part of the radio resources in the adjacent cell edge area. Cell edge radio resource redistribution.

However, after the radio resource is reallocated, the edge area of the neighboring cell is reduced due to the available radio resources, thereby increasing the overload probability of the neighboring cell edge area. Moreover, once the edge area of the neighboring cell is overloaded, it can only continue to request cell edge radio resource reallocation to other neighboring cells, and thus the chain reaction will cause the overload effect to spread, so that in a busy network, The resource allocation of the entire network may be in a state of volatility at all times.

Summary of the invention

The embodiments disclosed in the present invention will be specifically described below in conjunction with the accompanying drawings.

As shown in FIG. 3, the cell edge radio resource reallocation method embodiment of the present invention specifically includes the following steps:

Step 301: When the cell A is overloaded or the neighbor cell interference is too large, the cell adjacent to the cell A is selected, and an edge resource reconfiguration request message is sent to all or a specific neighbor cell, where the edge resource reconfiguration request message is sent. Contains the indication of the radio resource (ie, edge radio resource) that needs to be deactivated in the edge area of the neighboring cell and the time that it is desired to deactivate.

Step 302: The cell adjacent to the cell A determines whether the edge radio resource can be deactivated after receiving the edge resource reconfiguration request message, and if yes, proceeds to step 303, otherwise returns an edge radio resource reconfiguration request response to the cell A. Message, and proceeds to step 305, the edge radio resource reconfiguration request is ringing The response message includes information rejecting the edge radio resource reconfiguration request of cell A. It should be noted that the deactivation of the radio resource in the neighboring cell edge area may be implemented in multiple manners, for example, including but not limited to, the neighboring cell reduces power usage or disables some radio resources. In addition, the neighboring cell edge zone disables the radio resource, that is, the neighbor cell deactivates the edge radio resource.

Step 303: The neighboring cell that can disable the edge radio resource determines the edge radio resource to be deactivated and the deactivation time of the resource according to the edge resource reconfiguration request message according to the edge resource reconfiguration request message, that is, the edge radio to be deactivated. The resource determines a deactivation time. In an actual application, the edge radio resource deactivation time may be determined by the cell A alone, or may be determined by the neighboring cell that can disable the edge radio resource, or may be determined by the foregoing two.

Step 304: The neighboring cell that can disable the edge radio resource locks the radio resource to be deactivated determined in step 303, and sends an edge radio resource reconfiguration request response message to the cell A, the edge radio resource reconfiguration request response message. It includes radio resource information and resource deactivation time that the cell has locked.

Step 305: The cell A receives all the edge radio resource reconfiguration request response messages, and determines whether any of the edge radio resource reconfiguration request response messages includes the information of rejecting the edge radio resource reconfiguration request of the cell A, and if yes, the process ends. Otherwise, proceed to step 306;

Step 306: The cell A confirms, according to the received edge radio resource reconfiguration request response message, the radio resource deactivated by the neighbor cell edge area to be used and the deactivation time of the radio resource, and disables the radio resource. After the cell sends an acknowledgment message, the radio resource that is deactivated in the neighboring cell edge area is used.

Optionally, the cell A confirms that the used radio resource in the adjacent cell edge area is used, and re-configures the intersection of the radio resources that are allowed to be deactivated in the request response message for all the edge radio resources, and the acknowledged use The deactivation time of the radio resource is the shortest of the resource deactivation times allowed in all edge radio resource reconfiguration request response messages. Furthermore, the edge area of the cell A can use the radio resources that are disabled by the neighboring cell edge area. For convenience of description, the radio resources that are disabled in the adjacent cell edge area are simply referred to as the first radio resource. It should be noted that, whether the cell A or the neighboring cell has the first radio resource, but because of the particularity of the cell edge region, if the edge region of the neighboring cell uses the first radio resource, the edge region of the first cell The first wireless resource cannot be used (otherwise causing mutual interference), and vice versa. Therefore, only stop at the edge of the adjacent cell In the case of using the first radio resource, the edge area of the first cell can use the first radio resource.

Step 307: The deactivation time of the first radio resource expires, the edge area of the cell A automatically releases the used first radio resource, and the adjacent cell edge area of the first radio resource is deactivated to automatically recover the first radio resource. The right to use, that is, the neighboring cell can decide whether to use or not use the first radio resource in the edge zone according to its current resource condition.

In the foregoing step 307, the cell edge area adjacent to the cell A and deactivating the first radio resource, after restoring the normal use right to the first radio resource, if it is decided to use the first radio resource in the edge area, Preferably, the first radio resource is marked as available after a certain time, which can effectively avoid inter-cell interference caused by the cell A and the neighboring cell being out of synchronization.

Similarly, in the foregoing step 306, the cell A may also formally use the first radio resource after the neighboring cell of the first radio resource is deactivated and returns an acknowledgement response.

The cell edge radio resource redistribution method of the present invention can also implement the continuation of radio resources, including the following steps:

Step 401: When the cell A is overloaded or the neighbor cell interference is too large, select a cell adjacent to the cell A, and send an edge resource reconfiguration request message to all neighboring cells or a specific neighboring cell, where the edge resource reconfiguration is performed. The request message includes a radio resource indication that needs to be deactivated in the edge area of the neighboring cell and a time to be deactivated;

In step 402, the cell adjacent to the cell A determines whether the edge radio resource can be deactivated after receiving the edge resource reconfiguration request message, and if yes, proceeds to step 403, otherwise returns an edge radio resource reconfiguration request response to the cell A. The message, and proceeds to step 405, the edge radio resource reconfiguration request response message includes information rejecting the edge radio resource reconfiguration request of cell A.

Step 403: The cell that can disable the edge radio resource determines the corresponding edge radio resource to be deactivated and the deactivation time of the resource according to the edge resource reconfiguration request message according to the edge resource reconfiguration request message, that is, the edge wireless to be deactivated. The resource determines a deactivation time. In an actual application, the edge radio resource deactivation time may be determined by the cell A alone, or may be determined by the neighboring cell that can disable the edge radio resource, or may be determined by the foregoing two.

Step 404: The cell that can disable the edge radio resource locks the radio resource to be deactivated determined in step 403, and sends an edge radio resource reconfiguration request response message to the cell A, where the edge wireless The resource reconfiguration request response message includes radio resource information and resource deactivation time that the cell has locked.

Step 405: The cell A receives all the edge radio resource reconfiguration request response messages, and determines whether any of the edge radio resource reconfiguration request response messages includes the information of rejecting the edge radio resource reconfiguration request of the cell A, and if yes, the process ends. Otherwise, proceed to step 406;

Step 406: The cell confirms, according to all the received edge radio resource reconfiguration request response messages, the radio resources that are deactivated in the neighboring cell edge area that are to be used, and the deactivation time of the radio resources, and sends the cell to the radio resource. After the acknowledgment message is sent, the radio resources that are deactivated in the adjacent cell edge zone are used. Preferably, the cell A confirms that the used radio resource in the adjacent cell edge area is the intersection of the radio resources allowed to be deactivated in all the edge radio resource reconfiguration request response messages, and the determined radio resource The deactivation time is the shortest of the resource deactivation times allowed in all Edge Radio Resource Reconfiguration Request Response messages. Furthermore, the edge area of the cell A can use the radio resources deactivated in the neighboring cell edge area. For the convenience of the description, the radio resources deactivated in the adjacent cell edge area are simply referred to as the first radio resource.

Step 407: After a certain time before the expiration of the first radio resource deactivation time, the cell A determines whether the edge load is too heavy or the neighbor cell interference is too large. If yes, go to step 408, otherwise go to step 413; Step 408, cell A direction The cell that is adjacent to the first radio resource is configured to send a resource renewal request message, where the resource renewal request message includes the first radio resource information and a desired renewed time;

Step 409: The cell adjacent to the cell A and deactivating the first radio resource determines whether to approve the resource renewal request. If the process proceeds to step 410, the device returns a resource renewal request response message to the cell A, and proceeds to step 411. The edge radio resource reconfiguration request response message includes information that rejects the resource renewal request of the cell A;

Step 410: The cell that deactivates the first radio resource updates the resource deactivation time according to the resource status, and sends a resource renewing request response message to the cell A, where the resource renewing request response message includes the updated first radio resource. Deactivation time;

Step 411, the cell A receives all the resource renewal request response message, and determines whether any of the resource renewal request response message includes the information of the resource renewal request rejecting the cell A, if there is a step 413, otherwise proceeds to step 412;

Step 412: After receiving the resource renewal request response message, the cell A receives the updated first The line resource deactivation time updates the original deactivation time of the first radio resource, and thereafter continues to use the first radio resource deactivated in the adjacent cell edge area, and returns to step 407;

Step 413: The new radio resource new deactivation time expires, the cell A edge area automatically releases the used first radio resource, and the adjacent cell edge area of the first radio resource is deactivated to automatically resume the use of the first radio resource. The right, that is, the neighboring cell edge area may use the first radio resource.

In the foregoing step 413, after the cell edge area of the first radio resource is deactivated, after the right to use the first radio resource released by the cell A edge area is automatically acquired, preferably, the first radio resource is marked as Available, this can effectively avoid inter-cell interference caused by cell A and neighboring cells being out of sync.

Similarly, in step 410, the first radio resource may be officially used after waiting for neighboring cell A and deactivating all cell return acknowledgement messages of the first radio resource.

The cell edge radio resource reallocation method in the embodiment of the present invention may further update the deactivated edge radio resource information by the neighboring cell by using step 410, for example, the neighboring cell edge zone deactivates the second radio resource to replace the first radio. The resource then sends the updated second radio resource information and the deactivation time of the second radio resource to the cell A through the resource renewal request response message, and in step 412, the cell A receives the resource renewal request response. After the message, the edge area releases the first radio resource (because the deactivation time of the first radio resource expires), and uses the second radio resource deactivated by the new neighbor cell edge area according to the updated radio resource information, At the same time, the wireless resource deactivation time is updated as the deactivation time of the second radio resource. And return to step 407.

Please refer to FIG. 4 , which is a schematic structural diagram of an apparatus for processing cell edge radio resource reallocation according to the present invention. The apparatus of this embodiment specifically includes a deactivated resource scheduling unit 41, a deactivated failure condition determining unit 42, a first deactivated resource restoring unit 43, and a second deactivated resource restoring unit ⁴⁴ . The internal structure of the device will be further described below in conjunction with the working principle of the device of this embodiment.

First, the first cell edge zone is controlled by the deactivated resource scheduling unit 41 to use the first radio resource deactivated by its neighbor cell edge zone. Specifically, when the first cell edge area is overloaded or the interference of the neighboring cell edge area is excessive, the first cell requests cell edge radio resource reallocation to the neighboring cell, and further, the resource scheduling unit 41 is disabled. The neighboring cell edge area deactivates the first radio resource, that is, controls the neighboring cell to stop using the first radio resource in its edge area by deactivating or reducing power, and also controls the first cell edge area to use its neighboring cell. The first wireless resource that is deactivated. At the same time, it is also necessary to determine the deactivation failure condition of the radio resource by the deactivation failure condition determining unit 42, and the determined deactivation failure condition includes at least the deactivation failure condition of the first radio resource. Specifically, the deactivation failure condition determining unit 42 may control the first cell to determine the deactivation failure condition of the first radio resource, and may also control the neighboring cell to determine by itself, and may also control the first cell and the neighboring cell to jointly negotiate and determine. . In general, the deactivation failure condition is a deactivation time, that is, a deactivation time is determined for the first radio resource, and the deactivation time expires, and the determined deactivation failure condition is satisfied, and then the first stop is performed. Subsequent processing is performed by the resource restoring unit 43 and the second deactivated resource restoring unit 44.

Specifically, when the deactivation time expires (ie, the deactivation failure condition is satisfied), the first deactivated resource recovery unit 43 controls the first radio resource used by the first cell edge zone dry release, and is configured by the second deactivated resource. The recovery unit 44 controls the neighboring cell edge region to restore the right to use the first radio resource. Whether the first radio resource is actually used in the neighboring cell edge area may be determined according to the current resource status, and the neighboring cell edge area may use the first radio resource if necessary.

Further, it is considered that it is possible that the first cell edge area still needs to continue to use more radio resources when the deactivation time expires. If the first cell edge area releases the first radio resource at this time, it may cause itself to be overloaded. Therefore, an continuation processing unit can be added to the device. If the first cell determines that it needs to renew the radio resources that are deactivated in the neighboring cell edge area within a certain period of time before the expiration of the deactivation time, then the continuation processing unit processes the continuation of the first cell to the neighboring cell. request.

Specifically, the continuation processing unit includes a continuation request transmission processing unit and a continuation request reception processing subunit. The continuation request transmission processing sub-unit controls the first cell to determine whether it needs to renew the radio resources that are deactivated in the adjacent cell edge area, and if it is determined that the continuation is required, the first cell initiates a renewal request to the neighboring cell. Then, the renewal request receiving processing subunit controls the neighboring cell to agree or reject the renewal request of the first cell according to its resource status. If the renewal request receiving processing subunit agrees to the renewal request, the deactivation invalidation condition determining unit 42 is triggered to update the deactivation invalidation condition.

The continuation request receiving processing sub-unit agrees that the continuation request of the first cell has at least two processing situations, and one is that the neighboring cell edge area continues to disable the first radio resource and triggers the deactivation failure condition determining unit 42 as the A radio resource determines a new deactivation time, and further, the first cell edge zone can continue to use the first radio resource; in another case, the neighbor cell edge zone deactivates the second radio resource to replace the first radio resource, And triggering the deactivation failure condition determining unit 42 as the second radio resource Determining a deactivation time, and further, the first cell edge area starts to use the second radio resource. Of course, since the deactivation time of the first radio resource expires, the first cell edge area also releases the first radio resource.

Generally, the apparatus for controlling the resource allocation of each cell is on the base station side, and therefore the present invention also discloses a base station system, which includes the foregoing figures in addition to the conventional functional units of the existing base stations.

4 means for processing cell edge radio resource reallocation shown in the embodiment. As a specific implementation of the apparatus for processing cell edge radio resource reallocation has been described in detail above, and those skilled in the art can obtain the implementation method of the conventional base station conventional functional unit from the prior art, therefore, it is believed that the technology in the field A person can implement the base station system disclosed by the present invention.

In addition, it should be noted that the determined radio resource deactivation failure condition includes, but is not limited to, a deactivation time, for example, an edge area load condition, etc. In short, as long as a deactivation failure condition of a radio resource is determined, the neighboring cell can be guaranteed. The edge zone is able to restore the right to use the deactivated wireless resources in time. In addition, the determining manner of the deactivation failure condition includes, but is not limited to, notifying the neighboring cell after the first cell is determined, notifying the first cell after determining by the neighboring cell, or determining by the first cell and the neighboring cell. .

The method for reallocating the cell edge radio resource of the present invention, the device for processing the cell edge radio resource reallocation, and the like are described in detail by using a plurality of specific embodiments. It can be seen that, in the embodiment of the present invention, after the first radio resource is deactivated by using the first radio resource in the neighboring cell edge region, the first radio resource is released, and then the first radio resource is released. The neighboring cell edge area can restore the right to use the first radio resource, that is, the adjacent 'j, the area edge area can use the first radio resource. Therefore, the neighboring cell edge area is not redistributed by the previous edge radio resource, so that the first radio resource is always unavailable, and the probability of overloading the adjacent cell edge area is reduced compared with the prior art. The diffusion of the overload effect is preferably suppressed.

Further, by adopting the technical feature that the first cell edge area continues to use the radio resources deactivated by the adjacent cell edge area, the diversified resource conditions are better adapted, and the allocation of edge radio resources can be made more reasonable.

The above is only a plurality of specific embodiments of the present invention, and it should be noted that those skilled in the art can also make several improvements and retouchings without departing from the principles of the present invention. It should also be considered as the scope of protection of the present invention.
