Embodiment Construction

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0027] In order to meet the challenges of wireless broadband technology and enhance the competitiveness of future networks, the 3rd Generation Partnership Project (3GPP) has constructed a new evolved network system, which only retains the packet switching domain, so it also It is called the Evolved Packet System (EPS for short). In the EPS system...

Abstract

The invention provides a method, equipment and system for processing a voice call continuity service. The method comprises the following step that: in a process which is initiated by user equipment (UE) and is used for switching a voice service from a packet-switched (PS) domain network to a circuit-switched (CS) domain network, a mobility management entity (MME) controls to establish a data forwarding channel between a first network element of the PS domain network and a second network element of the CS domain network, wherein the process for switching the voice service from the PS domain network to the CS domain network comprises domain switching and access technology switching; and the data forwarding channel is used for forwarding voice data of the UE before the domain switching is completed. In the embodiment of the invention, the data forwarding channel between the PS domain network and the CS domain network which are used for establishing voice data is controlled before switching and conversion operation of single radio voice call continuity (SRVCC) is completed in the process which is initiated by the UE and is used for switching the voice service from the PS domain network to the CS domain network, so that longer interrupt time delay generated by the domain switching does not influence the length of the voice switching time delay of the SRVCC anymore, and the quality of the voice continuity of the SRVCC is enhanced.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a method, device and system for processing voice call continuity services. Background technique [0002] 2nd Generation (2G) or 3rd Generation (3G) networks, such as Global System for Mobile Communication (GSM) or Wideband Code Division Multiple Access (WCDMA) CodeDivision Multiple Access (WCDMA for short) network has formed a comprehensive coverage situation after years of deployment. At the same time, with the development of network technology, some pure PS domain networks that only provide Packet Switch (PS) such as System Architecture Evolution (SAE) / Long Term Evolution (PS) LTE), High Speed ​​Packet Access (HSPA for short), etc., have gradually covered some urban areas and traffic hot spots in the initial stage of network construction. Therefore, in the current communication network, these pure PS domain networks and 2G or 3G network...
