Description

This application claims priority to Chinese Patent Application No. 201010165638. 2, entitled "Cell-based Re-establishment Method and System Based on Hardware Failure", filed on April 30, 2010, the entire contents of which are incorporated by reference. Combined in this application.

TECHNICAL FIELD The present invention relates to the field of mobile communications, and in particular, to a cell re-establishment method and system based on hardware failure. BACKGROUND In mobile communication technology, a cell (CELL) is a basic area where a mobile communication system user resides, and its function implementation depends on multiple physical and logical sub-function blocks, such as an LTE (Long Term Evolution) system. The multiple physical sub-function blocks on which the implementation of the cell function depends, such as RRU (Remote Radio Unit), BBU (Base Band Unit), and the like, and multiple logical sub-function blocks such as L2 (including the intermediate chain) Layer, physical link control layer, packet translation protocol layer), L3 (Radio Resource Control Layer), L1 (physical layer), etc.

In a system, there may be multiple identical physical sub-function blocks, such as a single base station including multiple RRU boards and BBU boards. If a physical sub-function block is faulty, for example, the BBU board device is damaged, the capacity is reduced, or the board is faulty. The cell will re-establish the fault after the fault is initiated. At this time, the base station will accurately match the resource configuration of the current cell. If the resource configuration of the current cell cannot be satisfied, the user cell is failed to be established. At this time, it is necessary to wait for the resource shortage problem to be solved and then re-process the fault initiated by the cell, or wait for the user to manually reduce the configuration of the cell resource, and then perform an exact match again, and when the resource resource configuration can be satisfied. Live community.

In the process of implementing the present invention, the inventors have found that in the prior art, when a cell failure is re-established due to a hardware failure, it is necessary to accurately match the current cell resource configuration to determine whether the cell re-establishment is successful, when the exact match is unsuccessful. The user needs to manually modify the resource configuration of the cell, so as to perform exact matching again, so that the service interruption time is longer, and the stability of the system is greatly reduced. Summary of the invention

FIG. 8 is also a flowchart of a cell re-establishment system based on hardware failure according to an embodiment of the present 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, and not all of the embodiments. example. 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. In the prior art, when a cell failure is re-established after a cell failure, the current cell resource configuration needs to be accurately matched to determine whether the cell re-establishment is successful. When the exact match is not successful, the user needs to manually modify the resource configuration of the cell. , in order to make an exact match again. For example, if a device on a BBU of a base station is damaged, the capability of the board is degraded. For example, the BBU can support the baseband capability of 30M before the fault occurs. The baseband capability can be reduced to only 25M. On the board, three 10M cells are built, that is, three 10M cells use the physical resources of the BBU. The original capacity of the BBU can support the three cells. stand by. If the third cell is not supported, the third cell that cannot be supported initiates a re-establishment request after the failure, and the base station accurately matches whether the available resources can satisfy the 10M bandwidth on the current BBU board, and the base station determines the current BBU list. The board resource cannot be satisfied, and the third cell fails to be reestablished. After the user needs to manually modify the bandwidth of the cell to be 5M or less, the base station re-determines that the available resources of the current BBU board can meet the modified bandwidth requirement, and the third cell Only re-establish success. It can be seen that in the existing cell re-establishment technology based on hardware failure, the service interruption time is long, which greatly reduces the stability of the system. Embodiments of the present invention provide a cell re-establishment method based on hardware failure, to solve the existing The hardware failure causes the service interruption time to be long and the system stability to be low when the cell is re-established. Referring to FIG. 1, a hardware failure-based cell re-establishment method provided by an embodiment of the present invention includes the following steps.

S101: The base station receives a re-establishment request after a cell initiated by a cell that uses a physical function board that has a hardware failure.

As a basic area where the user of the mobile communication system resides, the function of the cell depends on multiple physical function boards, such as the RRU board and the BBU board. In a practical application, a cell uses some or all of the physical resources of a physical function board. When a physical function of a physical function board is faulty, the physical function of the physical board is reduced. The functionality cannot be continued. Generally, the cell performs a self-test on its function operation at regular intervals, or triggers a self-test when an abnormality occurs in the function operation, and when the cell finds all or part of the physical resources on the board due to the physical function used by the cell in the self-test. When a failure occurs, the request is re-established after the failure is initiated.

S102: The base station searches for at least one physical function board to find available resources that can satisfy the current resource configuration of the cell.

S103: If found, allocate the available resource, perform cell re-establishment, and end. S104: If not found, the resource configuration of the cell is decreased, and step S102 is performed. Further, after allocating the available resources for cell re-establishment, the method may further include: prompting whether there is inter-board migration during the cell re-establishment process, and whether there is a reduction of cell resource configuration, etc.

I R from, o

Each of the base stations of the mobile communication system (such as the LTE system) usually includes multiple function boards, such as the BBU board and the RRU board. In actual applications, multiple boards are usually built on the BBU board and/or the RRU board. A cell (that is, multiple cells use the physical resources of the BBU and/or the RRU). If a hardware failure occurs on a board, the cell that uses its physical resources will be affected. At this time, the affected cell will initiate. After the fault is re-established, the base station can search for other physical function boards in the base station after receiving the request, and adjust the cell resource configuration when not found. That is, the physical resources of the current resource configuration of the cell are searched for on the physical function board of the base station. When the resource is not found, the resource configuration of the cell is reduced, and the physical function is searched on the physical function board of the base station to implement the cell. Automatic re-establishment. It can be seen that the embodiment of the present invention can re-establish the cell after the fault is timely, and greatly reduce the interruption time of the service, thereby effectively improving the stability of the system.

In a practical application, after the resource configuration of the cell is reduced, the method further includes: determining whether the current resource configuration of the cell is lower than a minimum resource configuration of the cell, and if the resource is smaller than the minimum resource configuration of the cell, indicating the reduced cell The current resource configuration can not meet the minimum resource configuration requirement established by the cell, and the cell re-establishment fails. Otherwise, step S102 is performed to find an available resource that can satisfy the current resource configuration of the cell on at least one physical function board of the base station.

In the embodiment of the present invention, by reducing the resource allocation of the cell, the at least one physical function board of the base station is configured to find available resources that can meet the minimum resource configuration of the cell, thereby facilitating the maximum utilization of the available resources of the system. Referring to FIG. 2, in the embodiment of the present invention, the cell resource configuration is reduced by using the device, and the available resources that can meet the minimum resource configuration of the cell are found on the at least one physical function board.

S201: The base station searches for at least one physical function board to find available resources that can satisfy the current resource configuration of the cell.

S202: The base station searches for at least one physical function board to find available resources that can satisfy the current resource configuration of the cell; if found, step S203 is performed, otherwise step S204 is performed.

S203: Allocating the available resources, performing cell re-establishment, and ending.

S204: Reduce resource configuration of the cell.

S205: Determine whether the current resource configuration of the cell is lower than a minimum resource configuration of the cell, if yes, execute step S206; otherwise, execute step S202.

S206: The cell re-establishment fails and ends.

It can be seen that the embodiment of the present invention can further solve the problem in the prior art because the user has modified In the process, the current remaining capacity of the base station cannot be accurately known, resulting in the problem that the resource utilization cannot be maximized.

In actual applications, you can perform lookup matching by reducing the resource configuration according to the preset length. For example, the baseband bandwidth can be reduced by 10M, and the antenna specification can be single-received (that is, 1T1R). As a long-term reduction, to maximize the use of the system's available resources, try to ensure the quality of community services.

It should be noted that, in the embodiment of the present invention, reducing the resource configuration of the cell may include: reducing a baseband bandwidth specification of the cell; and/or decreasing an antenna specification of the cell, and the like.

The following describes how to adapt the cell resource configuration in practice to implement cell re-establishment.

Referring to Figure 3, the cell 1 uses the physical resources of the BBU board identified as BBI-1 in the ENB (E-NodeB, EUTRAN base station). The current resource configuration of the cell 1 is 10M for the baseband bandwidth and 2T2R for the antenna.

S301: If an antenna fails, the affected cell 1 re-establishes the request after initiating a fault.

S302: After receiving the request, the base station searches whether the available resources of the current cell 1 resource configuration are met on the board BBI-1. If not, the process proceeds to S303. If yes, the process proceeds to S305. The resource configuration of the current cell 1 is a baseband bandwidth specification of 10M and an antenna specification of 2T2R.

S303: The base station processes the current resource configuration of the cell 1, that is, adjusts the antenna specifications of the cell 1, and reduces the original 2T2R to 1T1R, and enters S304.

S304: Query whether the available resources of the current cell 1 resource configuration are available on the BBI-1, and if yes, perform cell re-establishment on the BBI-1 to maximize the available resources of the system. If it is still not found, the current resource configuration of the cell is continued to be lowered, and the search is continued until the minimum resource configuration of the cell is reduced. If the available resources that the board meets are still not found, the cell re-establishment fails and ends.

S305: Perform cell reconstruction on the single board BBI-1.

Referring to FIG. 4, the cell 1 uses the physical resources of the BBU board identified as BBI-1 in the ENB. The current resource configuration of the cell 1 is that the baseband bandwidth specification is 20M, and the antenna specification is 2T2R.

S401: If a device failure occurs on the board BBI, the affected cell 1 re-establishes the request after initiating the fault.

S402: After receiving the request, the base station searches whether the available resources of the current cell 1 resource configuration are met on the BBI of the board. If not, the process proceeds to S403. If yes, the process proceeds to S405. The resource configuration of the current cell 1 is a baseband bandwidth specification of 20M and an antenna specification of 2T2R.

S403: The base station processes the current resource configuration of the cell 1, that is, adjusts the current baseband bandwidth specification of the cell 1, and reduces the original 20M baseband bandwidth specification to the 10M baseband bandwidth specification, and enters S404.

S404: Check whether the available resources of the current cell 1 resource configuration are available on the BBI, and if yes, perform cell re-establishment on the BBI of the board. If it is still not found, the current resource configuration of the cell is continued to be lowered, and the search is continued until the minimum resource configuration of the cell. If the available resources are still not found, the cell re-establishment fails and ends.

S405: Perform cell reconstruction on the single board BBI.

It should be noted that the solutions mentioned in the embodiments corresponding to FIG. 3 and FIG. 4 can be used independently, that is, only one mode of reducing the current baseband bandwidth or antenna specifications is used in one adjustment process until the cell is lowered to the cell. A minimum resource configuration or a board that can find the available resources of the current cell 1 resource configuration in the current system; or may be used in combination, that is, during the adjustment process, the current baseband bandwidth or antenna specifications are simultaneously reduced until the cell is lowered to the cell. The minimum resource configuration or the board in the current system that can find the available resources of the current cell 1 resource configuration; can also be used interchangeably, that is, the current baseband bandwidth is reduced during the previous adjustment process, and the system is lowered during the second adjustment process. The antenna specification reduces the system antenna specification during the previous adjustment process, and reduces the current baseband bandwidth during the second adjustment process until it is reduced to the minimum resource configuration of the cell or found in the current system to satisfy the current cell 1 resource configuration. The board of the resource.

Referring to Figure 5, there are two BBU boards labeled BBI-1 and BBI-2 in the ENB, where the boards are The BBI-2 is an idle card, and the cell 1 uses the physical resources of the BBI-1. The current resource configuration of the cell 1 is 20M for the baseband bandwidth and 2T2R for the antenna.

S501: If a device fault occurs on the board BBI, the affected cell 1 re-establishes the request after the fault is initiated.

S502: After receiving the request, the base station searches whether the available resources of the current cell 1 resource configuration are met on the board BBI-1. If not, the process proceeds to S503. If yes, the process proceeds to S504. The resource configuration of the current cell 1 is a baseband bandwidth specification of 20M and an antenna specification of 2T2R.

S503: The base station searches for the available resources of the current cell 1 resource configuration on the BBI-2 of the board, and if yes, performs full-module inter-board migration on the cell 1, that is, the cell 1 is heavily weighted on the BBI-2 board. Established to maximize the utilization of the system's available resources, ending.

S504: Perform cell re-establishment on the board BBI-1.

The full-size inter-board migration refers to finding available resources that meet the conditions on other physical function boards of the base station without reducing the current resource configuration of the cell, and realizing reestablishment after the cell failure.

In another embodiment of the present invention, referring to FIG. 6, the available resources that can satisfy the current resource configuration of the cell on the at least one physical function board may specifically include:

S601: The base station searches for a physical function board currently corresponding to the cell to check whether there is an available resource that can meet the current resource configuration of the cell.

S602: If not found, look for available resources on the other physical function boards to meet the current resource configuration of the cell.

When the available resources that meet the current resource configuration of the cell are found on other physical function boards, the physical function of the cell is migrated and re-established, that is, the available resources allocated on other physical function boards are used to perform cell Re-established.

In the further solution of the embodiment of the present invention, the physical function board of the local cell is preferentially searched, and then the other physical function boards are searched for, so that the service interruption time can be further reduced, and the system stability is better. The other physical function board may be the base station except the cell. Other boards that are outside the board of the physical function.

In an actual application, in the process of using the physical function board to find whether there are available resources that meet the conditions, the embodiment of the present invention may also be combined with the method of reducing the resource configuration one by one, for example, in FIG. 3 or FIG. 4 or FIG. The method mentioned is used to find the available resources that meet the conditions for cell re-establishment. In the process of searching for the available physical resources of the current physical function board, the device can be searched by means of reducing the resource configuration. The minimum resource configuration of the cell is reduced. If the available resources of the current resource configuration are not found on the current physical function board, the other boards except the physical function boards corresponding to the current cell are found. In the process of searching for other boards, the method of reducing the resource configuration may be used to perform the method of reducing the resource configuration, which is in the scope of protection of the embodiment of the present invention. Referring to FIG. 7, an embodiment of the present invention provides an example of cell re-establishment based on hardware failure, and the method includes the following steps.

S701: The base station receives a re-establishment request after a fault is initiated by a cell that uses a physical function of a physical board of a hardware failure.

S702: The base station finds whether the current physical configuration board of the cell is configured to meet the current resource configuration of the cell, and if yes, executing step S709, if not, executing step S703.

S704: Full-size board migration, step S709 is performed.

The full-size inter-board migration refers to finding available resources that meet the conditions on the other physical function boards of the base station without reducing the current resource configuration of the cell, and realizing the re-establishment after the cell failure.

S705: The base station reduces the resource configuration of the current cell, and finds whether the current resource configuration of the cell is met on the physical function board that originally built the cell. If yes, step S709 is performed, and if not, step S706 is performed. S706: The base station searches whether the current resource configuration of the cell is satisfied on the other physical function boards. If yes, the process proceeds to step S707. If not, the process proceeds to step S708.

S707: Perform inter-board migration with the current resource configuration, and execute step S709.

S708: Determine whether the current resource configuration of the cell is equal to or lower than the minimum resource configuration, if yes, execute step S710; otherwise, proceed to step S705.

S709: Establish a cell, and prompt the user whether there is inter-board migration during the cell re-establishment process, and whether there is information such as reducing the resource configuration of the cell, and ending.

S710: The user is prompted to have no available resources, and the cell establishment fails.
