Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments. Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
As it is shown in figure 1, the embodiment of the present invention provides the access control method of a kind of node B cache, the method is performed by source base station, including:
101, source base station receives the request message carrying content identification that terminal sends;
Described source base station is the current base station of service terminal.
When 102, being absent from, in described source base station buffer memory, the content mated with described content identification, search the target BS depositing the content mated with described content identification;
Described target BS is: with the base station that can intercom mutually between described source base station.
Such as, described source base station and target BS are the base station adopting Mesh (wireless mesh) networking mode in certain area. Adopt and all can keep wireless interconnected between any two base station of Mesh (wireless mesh) networking mode.
103, the request message carrying described content identification is sent to described target BS.
After target BS receives the above-mentioned request message carrying described content identification, obtaining the content mated with described content identification, and be sent to described source base station, described content is sent to described terminal by source base station.
The embodiment of the present invention provides in application scenarios: when the hit rate of definition base station Cache (buffer memory) reaches 50%, it is necessary to the capacity of memorizer is 3TB. Assume to be required for providing the Cache of identical hit rate to service in 100 base stations, then when adopting prior art, it is necessary to altogether dispose the memorizer of 300TB in 100 base stations. And after adopting the method that the embodiment of the present invention provides, it is possible to the memorizer of 3TB capacity is distributed in 100 base stations, also that is, it needs to altogether dispose the memorizer of 3TB in 100 base stations. Thus, effectively reduce the hardware investment disposing buffer memory on base station, and terminal can access the content in above-mentioned 100 base stations on the Cache of any one base station, that is terminal can share the content of above-mentioned 100 base station Cache, thus, reach the effect identical with disposing 300TB memorizer and hit rate.
Can be seen that, in the embodiment of the present invention, after source base station receives the content identification that terminal sends, if described source base station buffer memory is absent from the content mated with described content identification, then search the target BS depositing the content mated with described content identification, and the request message carrying described content identification is sent to described target BS, in order to the content mated with described content identification is obtained from described target BS. That is, when terminal does not get content in the buffer memory of a base station, it is also possible to obtain from the buffer memory of other base stations, the buffer memory of multiple base stations achieves shared.
