Problems solved by technology

[0003] However, in the above process, since the eNB does not know the current status of the fallback cell, it may occur that when the mobile terminal falls back to the cell, the cell is in a congested state or other poor communication status refuses the mobile terminal to access, resulting in the mobile terminal The fallback fails, and the call cannot be established, which affects the user experience

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, and sends an extended service request to the MME.

[0053] Step S11: the MME instructs the eNB to send the configuration information of the fallback cell to the mobile terminal.

[0054] Wherein, the fallback cell configuration information includes multiple configured fallback cells.

[0055] Step S12: the mobile terminal receives the configuration information of the fallback cell, measures the configured fallback cell, and sends the measurement result to the eNB.

[0056] Step S13: The eNB processes the measurement results to obtain the best fallback cell. The best fallback cell is a fallback cell that allows access and has the best signal.

[0057] Step S14: the eNB instructs the mobile terminal to fall back to the best fallback cell.

[0058] Step S15: The mobile ter...

Embodiment 2

[0061] This embodiment provides a method for a mobile terminal to fall back to a cell, including:

[0062] Step S10: the mobile terminal receives the paging request sent by the MME, and sends an extended service request to the MME.

[0063] Step S11: the MME instructs the eNB to send the configuration information of the fallback cell to the mobile terminal.

[0064] Wherein, the fallback cell configuration information includes multiple configured fallback cells.

[0065] Step S12: the mobile terminal receives the configuration information of the fallback cell, measures the configured fallback cell, and sends the measurement result to the eNB.

[0066] Step S13: The eNB processes the measurement results to obtain the best fallback cell. The best fallback cell is a fallback cell that allows access and has the best signal.

[0067] This step specifically includes: figure 2 as shown,

[0068] Step S131: the eNB extracts the frequency point information of the n fallback cells w...

Embodiment 3

[0093] 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 image 3 As shown, it includes: a fallback request module 1, configured to receive a paging request sent by the MME, and send an extended service request to the MME. The first receiving module 2 is configured to receive the fallback cell configuration information sent by the eNB. The measurement module 3 is configured to measure the configured fallback cell and send the measurement result to the eNB. The processing module 4 is configured to process the measurement results to obtain the best fallback cell. The best fallback cell is a fallback cell that allows access and has the best signal. The second receiving module 5 is configured to receive an indication of falling back to the best fallback cell sent by the eNB. The fallback module 6 is configured to fallback to the best fallback cell according to the instruction.

Abstract

The invention provides a mobile terminal and a method for falling back to a cell. The method includes that the mobile terminal receives the paging request sent by the MME, and sends an extended service request to the MME; the MME instructs the eNB to send configuration information of the fallback cell to the mobile terminal; the mobile terminal receives the configuration information of the fallback cell, and measures the configured fallback cell, And send the measurement results to eNB; eNB processes the measurement results to obtain the best fallback cell; the best fallback cell is the fallback cell that allows access and has the best signal; eNB instructs the mobile terminal to fall back to the best fallback cell; mobile The terminal falls back to the best fallback cell according to the instruction. The method can avoid the situation that the mobile terminal is rejected because the fallback cell is in a congested state or other poor communication state, thereby ensuring that the mobile terminal can successfully fall back, establish a call smoothly, and improve user experience.

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. [0003] However, in the above process, since the eNB does not know the current status of the fallback cell, it may happen that when the mobile terminal falls back to the cell, the cell is in a congested state or other poor communication status and refus...
