Although the wide coverage of satellite system, current prior art does not have the supplementary access way of satellite system as LTE EPC, the communication system that this two systems are still independently run.The following embodiment of the disclosure, using the supplementary access way of satellite system as LTE EPC network, achieves the two-way switching of data service between rete mirabile.
Fig. 1 shows the overall network configuration diagram that the disclosure realizes rete mirabile switching.
As shown in Figure 1, in the architecture, terminal is the terminal of LTE/ satellite bimodulus, and it can detect simultaneously and receive LTE network signal and satellite network signal, and user uses same number, such as, and IMSI and mobile number.
User uses LTE/ satellite dual-mode terminal through the eNB equipment of LTE network, or the satellite of satellite network and the unification of satellite ground station equipment are by S1 interface (namely, interface between EPC and Access Network) be linked into the EPC core network of LTE, PGW(Packet DataNetwork Gateway in EPC, grouped data network gateway) equipment is as anchor point device access data network.

S204, judges the network type of the packet core network EPC of access evolution according to the intensity of the two kinds of network signals detected;
It is to be noted, when LTE network signal and satellite network signal are all stronger, can preferentially use LTE network signal, because satellite network signal achieves all standing, therefore when LTE network signal is more weak, supplemented by satellite network signal again, to guarantee that the data service of user can normally be carried out.
Particularly, judge according to the intensity of the two kinds of network signals detected that the step of the network type of the packet core network EPC of access evolution can comprise:
The intensity of the LTE network signal detected and LTE signal strength threshold are compared;
If the intensity of the LTE network signal detected higher than LTE signal strength threshold, then accesses EPC by LTE network, otherwise judge that whether the intensity of the satellite network signal detected is higher than satellite-signal strength threshold;
If the intensity of the satellite network signal detected higher than satellite-signal strength threshold, then accesses EPC by satellite network.
