Embodiment 1

[0043] The present invention provides a cell fallback method, including:

[0044] Step S1: Configure a correspondence table of different network cells and locations in the eNB, the content of the correspondence table includes the cell IDs of the first network, the second network and / or the coverage area overlapping with the first network cell Or the frequency point information of the third network cell, and the location information of the overlapping area;

[0045] Step S2: When there is an incoming call to call the 4G card of the mobile terminal, the eNB obtains the GPS location information of the mobile terminal, and then determines the location of the pre-fallback network of the mobile terminal according to the GPS location information of the mobile terminal and the location information of the overlapping area in the correspondence table. Cell frequency point information and send it to the mobile terminal;

[0046] Step S3: The mobile terminal falls back to the cell accord...

Embodiment 2

[0064] According to another aspect of the present invention, such as figure 2 As shown, the present invention also provides a cell fallback system, including: eNB1 and mobile terminal 2;

[0065] The eNB1 is used to configure a correspondence table of different network cells and locations, and the content of the correspondence table includes the cell IDs of the first network, the second network and / or the second network that overlaps with the coverage of the first network cell Frequency point information of the third network cell, and location information of the overlapping area;

[0066] The eNB1 is also used to obtain the GPS location information of the mobile terminal 2 when there is an incoming call to call the 4G card of the mobile terminal 2, and then determine the mobile terminal 2 according to the GPS location information of the mobile terminal 2 and the location information of the overlapping area in the correspondence table. The terminal pre-falls back to the cell ...

Abstract

The present invention provides a method for cell fallback, which includes: configuring a correspondence table of different network cells and locations in the eNB, the contents of which include the cell IDs of the first network, and the second cell IDs overlapping with the coverage of the first network cell. The frequency point information of the network and / or the third network cell, and the location information of the overlapping area; when there is an incoming call to call the terminal, the eNB obtains the GPS location information of the terminal, and then according to the location information and the overlapping area in the correspondence table The location information determines the cell frequency point information of the terminal pre-fallback network, and sends it to the terminal; the terminal falls back to the cell according to the cell frequency point, and sends a paging response to the MSC to establish a call. The invention also provides a corresponding system. The cell fallback method and system of the present invention omit the terminal's measurement of multiple cells of different systems, and the eNB instructs the terminal to fall back, which shortens the time for cell fallback, improves communication efficiency, and saves network resources.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a cell fallback method and a cell fallback system. Background technique [0002] A typical CSFB (Circuit Switched Fallback, circuit domain fallback) service process mainly includes joint attachment, location update, calling (MO) CSFB process, called (MT) CSFB process, and detachment. The basic idea of ​​the CSFB solution is that the terminal stays in the idle state of the LTE network or in the data service connection state. When there is a voice service demand (calling or called), the LTE (Long Term Evolution, long-term evolution) network assists to fall back to 2G / The 3G network establishes a voice service, and quickly returns to the LTE network after the call is completed. [0003] In the CSFB implementation process, when the mobile terminal has an incoming call, the eNB (evolved Node B, evolved Node B) sends the configured fallback cell identity and frequency ...
