Problems solved by technology
[0005] It can be seen that when some configuration data of an evolved base station changes, the adjacent evolved base stations cannot know the changed configuration data, which will lead to the scheduling failure of the adjacent evolved base stations; The update method of configuration data implemented by the air interface consumes a lot of air interface resources on the one hand, and on the other hand cannot fully reflect the various working states of adjacent serving cells, so it also limits its use scenarios

Embodiment
[0038] Such as Figure 4 As shown, evolved base station A and evolved base station B are adjacent base stations, the serving cells under the jurisdiction of evolved base station A are A1~Am, the serving cells under the jurisdiction of evolved base station B are B1~Bn, and serving cells A1 and B1 are adjacent serving cells . Among them, the serving cell A1 is an existing serving cell, and the configuration data of the serving cell has not changed in any way; the configuration data of the serving cells A2-A5 have been modified: the cell identities of the serving cell A2, the serving cell A4 and the serving cell A5 When a modification occurs, the physical layer identifier of the serving cell A3 is modified, and the frequency of the serving cell A4 is modified; the serving cell A6 is a newly added serving cell, and the serving cell A7 is a deleted serving cell.

The invention relates to an evolution base station and a method for updating configuration data between the evolution base stations. The method comprises the following steps: after a first evolution base station changes self configuration data, transmitting a request message carrying the changed configuration data to a second evolution base station; and after the second evolution base station receives the request message, updating the locally stored and changed configuration data. The evolution base station comprises a transmitting unit, a receiving unit, an updating unit and a storing unit. The invention dynamically updates the configuration data between the evolution base stations, reduces the dispatching failure rate of the target evolution base station and improves the switching performance of an LTE network under the condition of no space resource consumption and can be widely applied to an LTE system.
Description
technical field [0001] The invention relates to wireless network long-term evolution technology, in particular to an evolution base station and a method for updating configuration data between the evolution base stations. Background technique [0002] Such as figure 1 As shown, the wireless network long-term evolution (LTE, Long Term Evolution) system includes evolved base stations (ENB, Evolution Node Base) 21-2n and access gateways (aGw, accessGateway) 11-1m; wherein, the access gateways 11-1m are Part of the evolved packet core network (EPC, EvolvedPacket Core) 1, the interface between the evolved base station and the access gateway is the S1 interface, the evolved base station is connected to the evolved packet core network 1 through the access gateway, and the S1 interface supports multiple access gateways The connection relationship of interacting with multiple evolved base stations; the evolved base stations are interconnected in a grid mode through the X2 interface....
