Problems solved by technology

[0005] However, in the existing technology, when the cell reset fails, it will fall back to the LTE network, and first establish an RRC (RadioResourceControl) link. Under the active call or called page, the user / application layer will initiate a voice call again and perform the CSFB process again And the above-mentioned cell reset, resulting in link overhead, call delay, slow system response speed, affecting communication quality and user experience

Embodiment Construction

[0036] In order to make the purpose, features and effects of the present invention more obvious and understandable, the specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0037] Many specific details are set forth in the following description to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways than described here, so the present invention is not limited by the specific embodiments disclosed below.

[0038] Such as figure 1 As shown, when the LTE network is deployed, the coverage of the 2G network can be considered as full coverage of the entire range 10 to 12, while the 3G network may be continuous coverage of the range 11 and range 12, and the LTE network may achieve high-speed range 12. Coverage of data services.

[0039] In order to ensure the continuity of user services, combined with the progress of LTE, it is n...

Abstract

The invention relates to a cell change order method based on circuit switched domain fall back (CSFB). The method comprises the following steps: carrying out packet domain service in a current service cell based on a first communication network; if receiving notification of circuit switched domain service, falling back from a packet domain to a circuit switched domain, and selecting a first target adjacent region capable of carrying out the circuit switched domain service to carry out cell change order, the network type of the first target adjacent region being a second communication network; and if the cell change order fails, residing in the circuit switched domain continuously, a terminal carrying out cell selection and connecting to a second target cell capable of carrying out circuit switched domain service. The method can improve conversation establishment success rate, and thus communication quality is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for resetting a cell based on circuit domain fallback (CSFB). Background technique [0002] Circuit Switched Domain Fallback (CSFB for short) can enable user equipment (User Equipment, UE for short) to initiate circuit switched (Circuit Switched, CS for short) services such as voice and receive paging for CS services such as voice under LTE access, and can Correctly process the ongoing Packet Switching (PS) service of the terminal under the access of the Long Term Evolution (LTE for short) system. In CSFB technology, in the dual coverage area of ​​LTE and 2G / 3G, for voice, Location Services (LCS for short) and supplementary services, user equipment can trigger a fallback from LTE access to the second generation mobile communication technology (2rd- generation (2G for short) / third-generation mobile communication technology (3rd-generation, 3G for short) ne...
