Problems solved by technology

[0008] During the research and practice of the prior art, the inventor of the present invention found that the prior art solution is to let the NAT device keep the public address of the corresponding SIP signaling by frequently sending data between the terminal and the public network , the method of reserving the public network address of SIP signaling increases invalid and frequent information interaction between the terminal and the public network, and also increases the data processing load of related equipment

Embodiment 1

[0028] see figure 2 , is a flow chart of a routing processing method provided in Embodiment 1 of the present invention, and may specifically include:

[0029] Step 210, the gateway device receives the service data sent by the user terminal;

[0030] The gateway device can receive various service data sent by the terminal through the internal network, and the service data can be divided into two types: IMS service data and non-IMS service data.

[0031] Step 220, judging that the service data is IMS service data according to the information contained in the service data;

[0032] The gateway device may determine the type of the service data based on information such as the destination address of the data packet of the service data, or the APN corresponding to the packet bearer connection carrying the service data.

[0033] Step 230, the gateway device forwards the IMS service data to the border session controller;

[0034] When the gateway device determines that the service...

Embodiment 2

[0037] see image 3 , is a flow chart of a method for processing an IMS service provided in Embodiment 2 of the present invention, and may specifically include:

[0038] Step 310, receiving the IMS service data forwarded by the gateway device;

[0039] After the gateway device judges the route of the service data, it receives the IMS service data forwarded by the gateway device.

[0040] In step 320, the border session controller performs related network address translation and SIP application layer gateway functions, forwards the IMS service data, and keeps the public network address of the SIP signaling during the valid period of the corresponding terminal SIP signaling registration.

[0041]When the terminal initiates the first IMS service data, that is, a SIP registration message, the border session controller allocates the public network address of SIP signaling for the user terminal, and then allocates the public network address of the IMS media stream when necessary, a...

Embodiment 3

[0048] see Figure 5 , is a flow chart of an IMS service provided by Embodiment 3 of the present invention, and the specific steps may include:

[0049] Step 501, the terminal sends service data to the gateway device;

[0050] Described terminal can be mobile phone, PDA (Personal Digital Assistant, personal digital assistant) equipment, personal computer etc.; Described gateway device can be GGSN (Gateway GPRS SupportNode, gateway GPRS supports node), or the gateway device of other similar positions; The service data may be IMS service data or non-IMS service data.

[0051] A specific APN can be assigned to IMS service data, and for simplicity, all IMS service data can be assigned the same APN. The terminal can first initiate a packet data bearer connection through the specific APN, and the packet data bearer connection request message initiated by the terminal can include APN (Access Point Name, access point name) information. After the terminal successfully establishes a p...

Abstract

Embodiments of the invention disclose a route processing method, an IMS service processing method and related equipment. The IMS service processing method comprises: a border session controller receives IMS service data forwarded by a gateway device; executes the network address conversion and functions of application-level gateways of initiation session protocol SIP, and forwards the IMS service data; and a public net address of SIP signaling is reserved all the time in the valid period of registration of SIP at the corresponding terminal. In the technical proposal of the embodiments, the border session controller reserves the corresponding public net address in the valid period of registration of SIP for the terminal, the processing method is simple, and the invalid information interaction between the related equipment and data processing burden can also be reduced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a route processing method, an IMS service processing method and related equipment. Background technique [0002] With the in-depth development of communication technology, new multimedia communication methods are accepted by more and more people. Multimedia communication services include not only audio and video communication, but also instant messaging, co-location browsing, collaborative work, streaming media, etc., especially the integration of new communication methods and traditional voice communication methods. [0003] Based on the trend of Internet and telecommunications network integration, the goal of IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) based on the all-IP (Internet Protocol) service network architecture is to shield user access methods and control services according to personalized user data. The degree of openness of the capability provides ...
