Embodiment 1

[0051] This embodiment provides a method for a mobile terminal to fall back to a cell, such as figure 1 shown, including:

[0052] Step S10: The mobile terminal receives the paging request sent by the MME, saves its current location information and TAI information, and sends an extended service request to the MME.

[0053] Step S11: After the call ends, the mobile terminal saves the frequency point information of the drop-back cell.

[0054] Step S12: When the mobile terminal receives the paging request sent by the MME again, it judges whether the TAI information of the cell it is camping on at this time is consistent with the last TAI information.

[0055] If yes, execute step S13: measure whether the distance between the current location and the last location is smaller than the threshold. If yes, execute step S14: the mobile terminal performs fallback according to the frequency point information of the fallback cell saved last time.

[0056] Wherein, the threshold is the...

Embodiment 2

[0059] This embodiment provides a method for a mobile terminal to fall back to a cell, such as figure 2 shown, including:

[0060] Step S10: The mobile terminal receives the paging request sent by the MME, saves its current location information and TAI information, and sends an extended service request to the MME.

[0061] Step S11: After the call ends, the mobile terminal saves the frequency point information of the drop-back cell.

[0062] Step S12: When the mobile terminal receives the paging request sent by the MME again, it judges whether the TAI information of the cell it is camping on at this time is consistent with the last TAI information.

[0063] If yes, execute step S13: measure whether the distance between the current location and the last location is smaller than the threshold. Wherein, the threshold is the signal coverage range of a base station. If yes, execute step S14: the mobile terminal performs fallback according to the frequency point information of t...

Embodiment 3

[0086] Based on the method for the mobile terminal to fall back to the cell provided in Embodiment 2, this embodiment provides a mobile terminal, such as Figure 4 As shown, it includes: a fallback request module 1, configured to receive the paging request sent by the MME, save the current location information and TAI information of the mobile terminal, and send an extended service request to the MME. The saving module 2 is used for saving the frequency point information of the drop-back cell of the mobile terminal after the end of the call. The first judging module 3 is used for judging whether the TAI information of the cell where the mobile terminal is camped on at this time is consistent with the last TAI information when the mobile terminal receives the paging request sent by the MME again. The second judging module 4 is configured to measure whether the distance between the current location of the mobile terminal and the previous location is smaller than a threshold when...

Abstract

The invention provides a mobile terminal and a cell fallback method thereof. The method comprises the following steps: a mobile terminal receives a paging request sent by an MME, stores position information and TAI information of the paging request at the moment, and sends an expansion service request to the MME; after the call is finished, the mobile terminal stores the frequency point information of the fallback cell; when the mobile terminal receives the paging request sent by the MME again, whether the TAI information of the resident cell at the moment is consistent with the TAI information of the last time or not is judged; if yes, whether the distance between the position of the current time and the position of the last time is smaller than a threshold value or not is measured; and if yes, the mobile terminal carries out fallback according to the fallback cell frequency point information stored last time. According to the method, the cell fallback time of the mobile terminal is greatly shortened, so that the whole call establishment time of the mobile terminal is greatly shortened, and the user experience is improved.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a mobile terminal and a method for falling back to a cell. Background technique [0002] Currently, in the CSFB call implementation process, when the mobile terminal has an incoming call, the MSC sends a paging request to the MME, the MME sends a paging request to the mobile terminal, the mobile terminal receives the paging request sent by the MME, and the mobile terminal sends an extension call to the MME. For a service request, the mobile terminal measures the fallback cell and performs cell fallback after receiving the appropriate fallback cell determined and sent back by the eNB, thereby establishing a call. This makes the whole call setup time of the mobile terminal relatively long, and the user's perception is not good. Contents of the invention [0003] The present invention aims at the above-mentioned problems in the prior art, and provides a mobile...
