A user equipment and method for realizing voice service thereof

Abstract

The invention discloses user equipment and a method for realizing a voice service thereof. The user equipment comprises a storage module and a processing module, wherein the storage module is used for storing failure network identity information and a corresponding failure network type in advance; a processing module is used for acquiring the current network identity information of the user equipment when receiving a capacity inquiry message issued by a network side, and detecting whether the current network identity information and the failure network identity information stored by the storage module in advance are the same, if the current network identity information and the failure network identity information stored by the storage module in advance are the same, acquiring the failure network type corresponding to the failure network identity information, generating terminal capacity information according to the network type supported by the network equipment at present and the failure network type, and then sending the terminal capacity information to the network side. By use of the method disclosed by the invention, the CSFB flow failure caused by unreasonable network signal coverage can be avoided, the voice use experience of the 4G user is improved, and the intelligence level of the UE is improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a user equipment and a method for realizing a voice service. Background technique [0002] There is no Packet Switched (PS) voice service in the existing Long Term Evolution (LTE) communication network. That is to say, when the user equipment (User Equipment, UE) of the LTE network needs to perform voice services, the UE needs to first release the resources of the LTE network, and then select a cell under a different system (such as a 2G / 3G communication network) for access. Then, a circuit switched (Circuit Switched, CS) domain voice service is performed, and the above voice service processing process is called a circuit switched fall back (Circuit Switched Fall Back, CSFB) process. [0003] For the mobile network, the coverage of the mobile 2G network is much better than that of the 3G network. Therefore, the mobile CSFB solution is to fall back to the mobile 2G n...

Problems solved by technology

However, in the actual network, there are some areas with relatively special network signal coverage. For example, in a certain area, the signal coverage of China Unicom 4G and China Unicom 2G networks is good, but the signal coverage of China Unicom 3G network is poor.

At this time, during the CSFB process, the Unicom 4G user chooses to fall back to the Unicom 3G network, but fails to camp on the Unicom 3G frequency point, which leads to the failure of the user's voice call; and the call failure triggered by the CSFB process will not prompt the user to miss a connection Telephone, which seriously affects the voice experience of 4G users
