Description
Technical field
The present invention relates to communication technical field, in particular to the cooperative system between the collaboration method between a kind of terminated community, a kind of terminated community and a kind of terminal.
Background technology
At present, along with the use of intensive networking, operator constantly increases in basic network investment spending, and operator's profit constantly declines, and the deployment of intensive networking itself is also very difficult.5G (Fifth-generation, 5th third-generation mobile communication technology) network will support a large amount of terminals and connection, but while larger support capacity is provided, also needs to reduce the load caused core network, and can support to dispose more flexibly simultaneously.And existing small-cell (small cell) Shortcomings in the above technological challenge of reply, such as: the restriction etc. of the flexibility of deployment, the cost of deployment and application scenarios.Therefore, industry begins one's study and provides the small cell scheme accessed, i.e. terminated community T-SC (Terminal-Small Cell) based on terminal.
Existing small cell scheme comprises Femtocell (flying honeycomb), Picocell (mainly in order to solve the indoor wireless distribution system problem of specific region) etc.The realization of this scheme needs based on wired backhaul (signal tunnel) and needs to safeguard S1, S5 interface etc. of cell (community) to core network side.Therefore, existing small cell scheme cannot reduce the number of connection of terminal to the chain of command of core network.Simultaneously, EPC (Evolved Packet Core is linked into this framework, the packet-based core networks of evolution), be only applicable to the region deploying these communities, not good to such an extent as to wireless coverage cannot be provided or the region of backhaul cannot be provided for the network coverage, or under these scenes such as the vehicles (and the vehicles itself fail to provide focus to cover) in movement are upper, all cannot use.Existing scheme also comprises MiFi (portable wideband wireless device) router, this scheme is based on WLAN (Wireless Local Area Networks, WLAN (wireless local area network)) unauthorized frequency range, but easily disturbed to such an extent as to QoS (Quality of service) is difficult to be guaranteed.
Based on prior art, when multiple terminated community T-SC is in nearby sphere, if the cooperation of minizone is based on traditional X2 interface mode (e-NodeB (eNB, evolved base station) between interconnect interface, the direct transmission of supported data and signaling) carry out, then there is the problem of redundancy route, and need the Radio Resource taking grand network, this is disadvantageous for the coordination between T-SC and across the communication of the terminal of T-SC, as shown in Figure 1.
Therefore, the highly effective cooperation how realized between T-SC community becomes technical problem urgently to be resolved hurrily at present.
Summary of the invention
The present invention is just based on the problems referred to above, propose a kind of new technical scheme, the highly effective cooperation between terminated community (T-SC) can be realized, namely can reduce cooperation between terminated community to the dependence of grand network radio resources, and the network element solving X2 interface process is too many and problem that delay that is that cause is excessive.
