Abstract
The invention discloses a method for notifying cell scrambling conflict and a device thereof. The method comprises the following steps that: a first base station transmits a base station configuration updating request message to a second base station after a service cell or a neighbor cell of the service cell of the first base station updates the physical cell identity, and the base station configuration updating request message brings the physical cell identify updated for the service cell of the first base station or the neighbor cell of the service cell; and when the second base station detects that the updated physical cell identify of the first base station is conflicted or confused with the physical cell identify of the service cell or the neighbor cell of the service cell of the second base station, the second base station returns a base station configuration updating failure message to the first base station and demonstrates that the failure reason is the conflict or the confuse of the physical cell identify and brings the conflicted physical cell identify and the global cell identity. By adopting the method, the time delay of the valid configuration validation can be reduced, and the performance of the system can be improved.
Description
Technical field
The present invention relates to moving communicating field, particularly a kind of method and apparatus of notifying cell scrambling conflict.
Background technology
At LTE (Long Term Evolution, Long Term Evolution) in the system, in the process of the normal operation in base station, whenever ambient network all may change, for example increased new base station, perhaps the base station has changed cell parameter ECGI (EUTRAN cellular global identity, long evolving system cellular global identity), PCI (Physical Cell Identifier, Physical Cell Identifier) value, frequency etc.; At this moment, can be between the base station by the config update process of X2 interface, the service cell information of eNBs (base station) behind mutual variation the and the neighboring BS information of Serving cell comprise information such as PCI, CGI (Cell Global Identifier, cellular global identity), frequency.
Lift an example, when the neighboring BS information of the Serving cell of eNB1 or Serving cell changes, need change by this information of the relevant base station of eNB config update process notice.Fig. 1 is a base station configuration updating success process, as shown in the figure, if eNB2 can accept the new information of eNB1, then returns eNB config update response confirmation message; Fig. 2 is the base station configuration updating failure procedure, as shown in the figure, if eNB2 can not accept the new information of eNB1, then returns eNB config update failed message, and carries corresponding failure cause.
For the interference between the reduction system, identical PCI can not be used in two adjacent sub-districts with frequency, still, because the PCI of each sub-district, base station is the scrambler of physical layer, can adopt the mode of base station self-configuring, thereby the generation that can't avoid PCI to conflict/obscure.The PCI does not here conflict and is meant: any two adjacent co-frequency cells all can not use same PCI; PCI does not obscure and is meant: can not have any two co-frequency cells to use identical PCI in all adjacent areas of a sub-district.
The change of the other side base station relevant information is notified by the config update process in the base station, and these change and all might cause the PCI conflict or obscure.Also have along with the UE measurement reports and find the adjacent area, can take this to find that new PCI conflicts/obscures, therefore require in the running of base station, to possess lasting PCI collision detection ability, can find the generation that conflicts/obscure as early as possible, and correct these mistakes, improve network service quality.
The deficiencies in the prior art are: when owing between the neighbor cell PCI takes place and conflicts/when obscuring, the mechanism that does not have in the prior protocols to be fit to tells the other side base station PCI to conflict, the base station also just can't carry out follow-up at PCI conflict make effective action and solve the PCI conflict, may cause the increasing of base station configuration updating process time delay, reduce systematic function.
