Problems solved by technology

[0029] Aiming at the problem in the prior art that the network load is not considered in the negotiation of code selection, which leads to the inability to allocate enough resources for the session when the network is under high load, so that the session cannot proceed, the present invention provides a method for code selection based on network load and system to solve the above problems

Embodiment Construction

[0053] The core idea of ​​the present invention is that the user equipment UE selects the encoding type according to the load indicator set by the proxy call session control function P-CSCF and / or the congestion indicator set by the IP-CAN network element.

[0054] Further, when the UE is the calling UE, the P-CSCF is the P-CSCF of the called side, and the IP-CAN network element is the IP-CAN network element of the calling side; when the UE is the called side If the UE is called, the P-CSCF is the P-CSCF of the calling side, and the IP-CAN network element is the IP-CAN network element of the called side.

[0055] Preferably, the IP-CAN network element setting the congestion indication specifically includes one or a combination of the following methods: Method 1: When the IP-CAN network element on the calling side detects its own congestion, the P-CSCF on the calling side The IP packet header of the sent SIP message sets the first congestion indication; mode 2: when the called ...

Abstract

The invention relates to a network load-based coding and decoding selection method and a network load-based coding and decoding selection system, and discloses a network load-based coding selection method and a network load-based coding selection system. The method comprises that: user equipment (UE) selects a coding type according to a load indication set by a proxy call session control function (P-CSCF) and / or a congestion indication set by an Internet protocol connectivity access network (IP-CAN) network element. The invention also provides the network load-based coding selection system, which comprises the UE, the P-CSCF and a user plane bearer network element, wherein the UE is used for selecting the coding type according to the load indication set by the P-CSCF and / or the congestion indication set by the IP / CAN network element. By the method and the system, the problem that enough resources cannot be allocated to a session in the high load state of a network to make the session cannot be performed because a network load is not taken into account in coding selection negotiation can be solved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and system for encoding selection based on network load in an IP (Internet Protocol, IP for short) multimedia subsystem. Background technique [0002] IP (Internet Protocol, referred to as IP) multimedia subsystem (IP Multimedia Core Network Subsystem, referred to as IMS) is an IP-based network proposed by the 3rd Generation Partnership Project (3GPP) Architecture, which builds an open and flexible business environment, supports multimedia applications, and provides users with rich multimedia services (such as figure 1 shown). [0003] IMS signaling and service data are carried on IP-CAN (IP Connectivity Access Network, IP connection access network). Since IMS is connected with the access gateway, IP-CAN can be GPRS (General Packet Radio Service, general packet radio service), WLAN (Wireless Local Area Network, wireless local area network), GSM (Global System for Mobi...
