Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.

The schematic flow sheet of the method for a kind of air interface synchronization that provides for the embodiment of the invention as Fig. 1 as shown in Figure 1, comprising:

101, the base station controller information that will comprise the clock of described base station controller is sent to each non-base station of described base station controller control, so that each non-base station is adjusted into the clock synchronous with the clock of described base station controller with clock;

The synchronous clock of above-mentioned and clock base station controller refers to, clock with base station controller is reference clock, generate the clock synchronous with the clock of base station controller, if, the clock of base station controller is the clock of 2M, after the base station receives this clock, can be reference clock with the clock of this 2M just, generate the clock of 13M.The clock that can realize all non-base stations under the base station controller like this all is synchronous.

As a kind of optional execution mode, the clock of base station controller can the network at base station controller place in the clock of unified appointment, so just can realize that the clock of all base station controllers is synchronous under the consolidated network.More than just can obtain that the clock of each non-base station is synchronous under the consolidated network.For example: the clock of base station controller can be to generate by the soft method of synchronization of eating dishes without rice or wine in the network at this base station controller place, namely all base station controllers send separately clock information mutually in the network at this base station controller place, by analyzing clock information, adjusting clock separately, is synchronous with the clock of realizing all base station controllers in this network.

As a kind of optional execution mode, the clock of the base station of working under the base station controller also can be can the network at base station controller place in the clock of unified appointment, for example, the clock of base station is unified appointment in the network at base station controller place, the clock that the pulse signal that appointment sends according to satellite generates, the clock of base station controller then can be the clock synchronous with the clock of base station, and the clock that just can realize base station controller is that network is unified appointment.Perhaps, the clock of base station is that the clock with base station controller is reference clock, and the synchronous clock of the clock of generation and base station controller, and the clock of base station controller is unified appointment in the network, the clock that so just can realize base station also is unified appointment in the network.So just can realize that the clock of all non-base stations and base station is synchronous under the base station controller, be synchronous with the clock of realizing base stations all under the consolidated network.

102, base station controller is benchmark with the frame information of the base station of described base station controller control, calculate the difference value of frame information and the described benchmark of each non-base station respectively, and generate the frame offset information of each described non-base station according to the difference value of each non-base station; The frame information of described base station is based on and obtains by global positioning system core card that the clock of temporal information that satellite sends and institute's base station generates, and the clock of described base station and the clock of described base station controller are synchronous;

As a kind of execution mode, base station controller will get access to the frame information of each non-base station and the frame information of base station before step 102.For example: subscriber equipment that can be by under the base station service and the behavioural information of the subscriber equipment under each non-base station service, obtain the frame information of base station and each non-base station.

Need to prove, comprise frame information in the above-mentioned behavioural information, for example: the control information that subscriber equipment sends to base station controller or request message etc., and subscriber equipment is served under certain base station, subscriber equipment sends behavioural information to base station controller under this base station service like this, information just needs to use that frame sends behavioural information to base station controller shown in the frame information of this base station the behavior so, base station controller just can obtain the frame information of this base station from behavior information like this, thereby can get access to the frame information of said reference station and each non-base station.

103, base station controller is sent to each non-base station respectively with the frame offset information of described generation, so that described each non-base station is adjusted into the frame information synchronous with described benchmark according to the frame offset information that receives with frame information.

The frame information that can realize all base stations under the base station controller (comprising: non-base station and base station) by step 102 and step 103 is synchronous, temporal information that satellite sends generates and the clock of base station is based on, that is to say, the frame information of the base station of working under each base station controller under the consolidated network is based on that temporal information that satellite sends generates, and just can realize that the frame information of each base station is synchronous under the consolidated network.More than just can obtain that the frame information of each base station is synchronous under the network.

In sum, the clock of all base stations and frame information all are synchronous under the network, and the interface-free resources of all base stations is synchronous under the consolidated network with regard to obtaining.And the GPS core card that has only base station to install in the embodiment of the invention, compared to existing technology in each base station and base station controller GPS is installed, the embodiment of the invention just can reduce the cost of communication system.

Optionally, above-mentioned non-base station can refer to not install the base station of global positioning system core card; The said reference station can refer to be equipped with the base station of GPS.

Fig. 2 is the schematic flow sheet of the method for the another kind of air interface synchronization that provides of the embodiment of the invention, and in the present embodiment, base station controller is equipped with GPS core card, as shown in Figure 2, comprising:

201, base station controller is by the pulse signal of described GPS core clamping receiving satellite transmission.

202, base station controller generates the clock of base station controller according to the pulse signal that receives.
