Problems solved by technology

Once any point in the communication link, or the signaling interaction between the calling party and the SIP proxy server, or the signaling interaction between the SIP proxy server and the switching center is abnormal, it will result in invalid application of wireless resources or failure to release wireless resources, especially on the called side. An abnormality in the signaling interaction of the local wireless communication system on the calling side directly leads to invalid occupancy of the channel of the local wireless communication system on the calling side, or even failure to release it, resulting in low utilization of wireless resources and affecting system performance

Embodiment 1

[0080] First, if Figure 4 The shown caller initiates a call, the R-R signaling interaction process between the caller via the local wireless communication system, the calling side SIP proxy server and the information center.

[0081] The caller transmits the session invitation signaling to the SIP proxy server on the calling side through the wireless communication system, and the SIP proxy server on the calling side extracts information such as calling priority, business priority, required channel, and media type as a wireless communication resource application necessary parameters. Wherein, the session invitation signaling may be INVITE signaling.

[0082] As a user terminal, the calling party can be any communication terminal connected to the wireless communication system, such as a mobile phone, a handheld computer, a PC, a notebook, and the like.

[0083] The wireless communication system can also be any type of wireless communication system, it can be a 2G mobile commu...

Embodiment 2

[0091] In the process of embodiment 1, the switching center processes the relevant fields in the session invitation signaling and confirms the answer call, which involves the signaling interaction between the switching center and the called party, such as Figure 5 As shown, the R-R process of signaling interaction at the called side when the called party answers.

[0092] The switching center transmits the INVITE signaling to the SIP proxy server on the called side, and the SIP proxy server on the called side extracts information such as calling priority, service priority, required channel, media type, etc., and communicates as the SIP proxy server on the called side to the wireless Necessary parameters when the system applies for wireless communication resources.

[0093] The SIP proxy server on the called side sends 100 (Trying) signaling to the switching center to indicate that the SIP proxy server on the called side is processing the call, and the SIP proxy server on the ca...

Embodiment 3

[0099] Such as Image 6 As shown, the R-R signaling interaction process when the SIP proxy server on the calling side fails to apply for wireless resources from the wireless communication system is described. In this signaling interaction process, it mainly involves that once the called party confirms the response, and the wireless resources such as wireless channel resources on the called side have been successfully applied for, and the wireless resource application on the calling side is unsuccessful, the called party The release of wireless resources on the side and the release of the calling party.

[0100] The INVITE message is transmitted to the SIP proxy server on the calling side through the wireless communication system, and the SIP proxy server on the calling side sends a 100 (Trying) signaling to the calling party to indicate that the SIP proxy server on the calling side is processing, and at the same time, the SIP proxy server forwards the INVITE signaling to the ...

Abstract

The invention provides a method for achieving wireless resource application of a wireless communication system based on an SIP protocol. The method includes the following steps: (1) a first SIP proxy server receiving a conversation request signaling which is launched by a calling party, and extracting necessary parameters of the wireless communication resource application; (2) the first SIP proxy server sending the signaling under processing to the calling party, and meanwhile forwarding the conversation invitation signaling to a switching center; (3) the switching center processing the conversation invitation signaling, and sending an instruction signaling to the first SIP proxy server; and (4) the first SIP proxy server building conversation action after receiving the instruction signaling. Invalid occupancy of local wireless communication channel resources can be effectively avoided, and communication capacity of the system is improved.

Description

technical field [0001] The present invention relates to wireless communication, in particular to a method for realizing resource application of a wireless communication system based on Session Initiation Protocol (SIP). Background technique [0002] SIP (Session Initiation Protocol, Session Initiation Protocol) is an application layer protocol that establishes, modifies, and terminates multimedia sessions in an IP network. It is part of the multimedia protocol system that the Internet Engineering Task Force (IETF) is constantly standardizing. SIP is described as being used to create, modify and terminate sessions between one or more participants. These sessions include Internet multimedia conferences, Internet or any IP network telephony calls and multimedia distribution, and members in the sessions can communicate through multicast or unicast connected networks. [0003] The SIP protocol does not care about the bearer network, and can work in a variety of telecommunication...
