Embodiment Construction

[0304] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. . Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0305] In addition, in such figure 1 Under the system structure shown, the voice stream is carried on a resource block (RB, Radio Bearer) with a Quality of Service Class Identifier (QCI) of 1, based on the Real-time Transport Protocol (RTP) / User Datagram Protocol (UDP) / IP protocol; SIP signaling is carried on RB with QCI 5, based on UDP / Transmission Control Protocol (Transmission Control Protocol, TCP) / IP protocol. Typically,...

Abstract

The invention provides a voice data transmission control method and device. The method of a wireless access network device on a calling terminal side comprises the following steps: the wireless access network device sends first configuration information to the calling terminal after receiving a connection establishment request from a calling terminal, and establishes a first signaling connection based on a voice special domain with the calling terminal; the wireless access network device receives a call establishment request sent by the calling terminal through the first signaling connection; and the wireless access network device sends the call establishment request to a core network device and establishes a second signaling connection based on the voice special domain with the core network device. As the voice service is established by the signaling connection based on the voice special domain, the IMS does not need to be superposed to the core network, therefore the functional network element of voice transmission control can be simplified, the delay of a service establishment flow is reduced, and the service establishment efficiency is improved.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a voice data transmission control method and equipment. Background technique [0002] With the explosion of data services and the full Internet Protocol (IP) of the network, the Long Term Evolution (LTE) network no longer provides the Circuit Switched (CS) domain, and only retains a single packet switch (packet switching, PS) domain: Evolved Packet Core (EPC). Therefore, the LTE network is an all-IP network without CS circuit domain. In the LTE network, it is necessary to provide IP voice services based on the PS packet domain, namely Voice over LTE (VoLTE). Therefore, the IP Multimedia Subsystem (IP Multimedia Subsystem) is introduced. , IMS), superimposed on the LTE core network. The VoLTE system uses the IMS system to implement service control, and the EPC system to implement bearer, so as to implement IMS-based packet domain voice and multimedia services. For use...
