Abstract

The invention provides a method for implementing LTE system voice business and a single-chip terminal. A single chip of the single-chip terminal comprises a terminal device processor and a mobile device processor. The terminal device processor is used for receiving a voice calling request. According to a received voice calling request, the mobile device processor establishes EPS bearing. By the EPS bearing, register and / or authentication are requested from a CSCF. After the register and / or authentication are successful, the received voice calling request is converted into a voice calling request complying with a SIP protocol. A converted voice calling request is transmitted to the mobile device processor after packaged in an IP data pack complying with an IP protocol. The mobile device processor is used for transmitting the IP data pack to an IMS server in order to use the EPS bearing via the IMS server to perform voice conversation between the single-chip terminal and a called terminal. The method achieves long term evolution system voice business of the single-chip terminal.

Description

technical field

[0001] The present invention relates to the field of communication technologies, in particular to a voice service implementation method of an LTE (Long Term Evolution, long-term evolution) system and an LTE single-chip terminal. Background technique

[0002] The LTE project is the evolution of 3G. Under the 2G and 3G networks, the voice service is mainly implemented in the CS (Circuit Switch, circuit switching) domain, while LTE is based on the packet switching service, only the PS (Package Switch, packet switching) domain. There is no CS domain. Therefore, to implement voice services on LTE terminals, other approaches are required.

[0003] At present, the solutions proposed by the industry around LTE voice services include: (1) SVLTE (simultaneous voice and LTE, simultaneous voice and LTE) solution, in which the terminal resides in both 2G / 3G and LTE networks , the traditional CS domain provides voice services, the LTE network provides data services, data...
