Embodiment Construction

[0053] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0054]IMS is introduced by 3GPP (3rd Generation Partnership Project) Release 5. Release 5 defines the basic structure of IMS. The work carried out in Release 6 focuses on various enhanced services of IMS. IMS superimposes a call and service control system on the PS domain. Realized the real PS domain voice call and business control. When a user initiates an IMSVoLTE voice call, the IMS internal network element P-CSCF (Proxy-Call Session Control Function, proxy call session control function) carries the media description information and the EPC network element PCRF (Policy ...

Abstract

The invention relates to a session management method, a device and a system, wherein, the session management method implemented from the perspective of PCRF comprises the following steps of: receivingan AAR message of the current Rx session sent by the P-CSCF; associating the current Rx session with the Gx session associated with the previous Rx session based on the preset maintenance relationship and the AAR message. The preset maintenance relationship is the correspondence between the Gx session identifier of the Gx session and the user equipment address. The current Rx session is associated with the Gx session associated with the previous Rx session, which in turn enables a single Gx session to be associated with multiple Rx sessions, enabling session management for multi-party calls.The present application enhances the types of services supported by the IMS system, enabling the system to support rich VoLTE multi-party communication application scenarios. The present application provides an Rx session management method applicable to an IMSVoLTE multi-party call process, which solves the Rx session management problem in the multi-party call process, and further ensures that theVoLTE multi-party call can be normally carried out.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a session management method, device and system. Background technique [0002] The trend of mobile, broadband and IP (Internet Protocol, Internet Protocol) in telecommunications technology business is becoming more and more obvious. Mobile communication technology is in a critical period of network technology evolution. At this time, LTE (Long Term Evolution, long-term evolution) came into being pregnancy. As a unified standard for next-generation mobile communications, LTE has multiple advantages such as high spectral efficiency, high peak rate, high mobility, and flat network architecture. An evolved platform that can provide a variety of wireless access technologies and diverse services, and can support the seamless switching of these services between these wireless access technologies; can realize the flattening and IP of the network; can provide high ban...
