Embodiment 1
[0028] figure 1 It is a preferred structural diagram of a search system of an LTE network according to an embodiment of the present invention, such as figure 1 As shown, the search system of the LTE network includes: a terminal 102, wherein the terminal includes: a receiving unit 1021, which is used to enter a network of other standards after the terminal exits from the LTE network and receive the LTE information of the LA under the jurisdiction of the MSC sent by the MSC. Network coverage information, wherein the LTE network coverage information is used to indicate whether the LA under jurisdiction supports LTE network coverage; the search unit 1022 communicates with the receiving unit 1021, and is used to search for LTE in LAs that support LTE network coverage according to the LTE network coverage information network. Preferably, the aforementioned network of other standards refers to a network of a different standard from the LTE network, for example, including: a TD-SCDMA...

[0037] exist Figure 1-4 On the basis of, the present invention provides a kind of search method of preferred LTE network, as Figure 5 As shown, the search method of the LTE network includes:
[0038] S502: The terminal exiting the LTE network receives the LTE network coverage information of the LA under the jurisdiction of the MSC sent by the MSC after entering a network of other standards, wherein the LTE network coverage information is used to indicate whether the under jurisdiction of the LA supports LTE network coverage;
[0039] S504: The terminal exiting the LTE network searches for the LTE network in the LA supporting the LTE network coverage according to the LTE network coverage information. Preferably, the aforementioned network of other standards refers to a network of a different standard from the LTE network, for example, including: a TD-SCDMA network, a WCDMA network, a CDMA2000 network or a GSM network.
[0040] In the above-mentioned preferred embodiment, af...
Embodiment 3
[0048] On the basis of the above-mentioned preferred embodiments, the present invention provides another preferred method of the LTE network search method, such as Image 6 As shown, the search method of the LTE network includes:
[0049] S602: The terminal normally camps on the LTE network, and measures the situation of other wireless access technologies. In this case, the general LTE base station information will broadcast the information of neighboring cells of different systems;
[0050] S604: The terminal reselects to another standard cell in the idle state or reselects to another standard cell after losing LTE network coverage (equivalent to the terminal exiting the LTE network);
[0051] S606: After the terminal enters a cell of other standards, initiate a location update process;
[0052]S608: The MSC saves the LTE network coverage information corresponding to the cell in the LA under its jurisdiction, and indicates whether the LA corresponding to the LAI has LTE netw...
