Problems solved by technology

Considering that when cross-domain, the delay of IMS signaling is relatively large, and many data packets are discarded, resulting in service interruption and affecting user experience
[0020] In other scenarios, such as UE 1 updating the IP address, or UE 1 updating the IP address and port number at the same time, the problem of data service interruption will occur

Embodiment 1

[0062] figure 2 It is a schematic flow chart of Embodiment 1 of the method for implementing service continuity during the media plane update process of the present invention, as shown in figure 2 As shown, the method includes the following steps:

[0063] UE 1 on the originating side communicates with UE 2 on the terminating side. The media plane addresses and ports involved are: the receiving address of UE 1 on the initiating side is Address 11, the port is Port 11, and the receiving address of UE2 on the terminating side is Address 21, the port is Port21; at a certain moment, UE 1 decides to change the port on the media plane to Port12; where, since this embodiment only involves the interaction on the originating side, the following PGW, PCRF, P- Both CSCF and UE 1 are devices located at the calling side.

[0064] Step 201, the P-CSCF receives the IMS update message sent by UE 1, which carries the SDP offer, and is used for UE 1 on the calling side to request to change t...

Embodiment 2

[0079] image 3 It is a schematic flow diagram of Embodiment 2 of the method for implementing service continuity during the process of updating the media plane in the present invention, as shown in image 3 As shown, the method includes the following steps:

[0080] UE 1 on the originating side communicates with UE 2 on the terminating side, and the media plane addresses and ports involved: the receiving address of UE 1 on the initiating side is Address 11, the port is Port 11, and the receiving address of UE 2 on the terminating side It is Address 21, and the port is Port 21; at some point, UE 1 decides to change the port on the media plane to Port 12.

[0081] Steps 301 to 310 are the same as steps 201 to 210.

[0082] In step 311, the P-GW starts a preset timer.

[0083] Step 312, when the started timer expires, the P-GW deletes the port Port 11 of UE 1 in the flow description information of the PCC rule corresponding to the service information (that is, closes the port ...

Embodiment 3

[0085] Figure 4 It is a schematic flow diagram of Embodiment 3 of the method for realizing business continuity during the process of updating the media plane in the present invention, as shown in Figure 4 As shown, the method includes the following steps:

[0086] UE 1 on the originating side communicates with UE 2 on the terminating side, and the media plane addresses and ports involved: the receiving address of UE 1 on the initiating side is Address 11, the port is Port 11, and the receiving address of UE 2 on the terminating side It is Address 21, and the port is Port 21; at some point, UE 1 decides to change the port on the media plane to Port 12.

[0087] Steps 401 to 407 are the same as steps 201 to 207.

[0088] Step 408, PCRF updates the local PCC rule according to the new flow description information in the received service information, that is, in the flow description information of the PCC rule corresponding to the service data flow of the service information, t...

Abstract

The invention discloses a method for realizing service continuity in the process of updating the media plane, comprising: in the process of updating the media plane, the call session control function proxy server (P-CSCF) at the originating side receives the Portable Session Description Protocol Provided (SDP offer), the policy and charging rule function entity (PCRF) on the originating side notifies the gateway on the originating side to open the updated port; after the update of the media plane is completed, the gateway on the originating side closes the port before the update ; The present invention also provides a system for realizing service continuity during the update process of the media plane. According to the technical scheme of the present invention, it is possible to avoid the interruption of the downlink media data when the port is switched during the update process of the media plane.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and system for realizing service continuity during media plane updating. Background technique [0002] The communication network based on Internet Protocol (IP, Internet Protocol) of the access gateway includes Next Generation Network (NGN, Next Generation Network), IP Multimedia Subsystem (IMS, IPMultimedia CoreNetwork Subsystem), Web-based real-time communication network (RTCWeb, RealTime Communication on Web) and other networks, networks that provide users with business capabilities, including real-time communication services such as voice communication and video communication, belong to the category of business networks. The access network includes a circuit switching domain (CS domain, Circuit Switched Domain) access network and a packet switching domain (PS domain, Packet Switching Domain) access network, and the CS domain access network includes a global system f...
