no. 2 approach

[0018] see again figure 1 , the present invention provides a second embodiment of a packet service network device, which includes a session control unit 120 and a service control unit 110 .

[0019] The session control unit 120 is used for connecting the user group 130 through the SIP protocol, and transmitting the user group information through the SIP protocol. In this embodiment, the session control unit 120 provides an IMS session routing function, that is, a call session control function (CSCF, Call Session Control Function). The protocol of the E1 interface between the session control unit 120 and the service control unit 110 is SIP, and the protocol of the E2 interface between the session control unit 120 and the user group 130 is SIP. The E1 interface is an ISC interface in the IMS network, and the E2 interface is a Gm interface in the IMS network.

[0020] The user group here refers to the SIP user terminals in a group, that is, IP Centex users.

[0021] The group ...

Embodiment approach 1

[0136] Implementation mode 1: PBX group users act as called parties

[0137] Include the following steps:

[0138] 1) The calling user A initiates a call request and calls the PBX group user B;

[0139] This step is to carry out session control through SIP agreement, obtain the process of user group information;

[0140] Calling user A may be located on a traditional circuit network or an IMS network.

[0141] When the calling user A is located on the traditional circuit network, the called number of the call request can carry the group reference identifier of the PBX group user, such as the group reference number 28780808; the traditional circuit network sends the IAM message of the ISUP protocol to MGCF, the message carries the group reference number 28780808; MGCF converts the above IAM message into a SIP INVITE message, and carries the group reference identifier of the PBX group user in the RequestURI parameter, and the RequestURI is TEL: 28780808; the SIP INVITE request...

Embodiment approach 2

[0154] Implementation Mode 2: CUG Service

[0155] Include the following steps:

[0156] 1) IMS user A initiates a call request, and the called user B of the same CUG group;

[0157] When the calling user A is on the IMS network, and initiates a call request to call user B in the CUG group, the calling user A carries the user ID of the called user B in the RequestURI parameter of the SIP call request INVITE message, for example, the RequestURI is SIP:userB@ chinalecom.com; the SIP INVITE request is forwarded to the session control unit where the calling user A is located;

[0158] The session control unit where calling user A is located inserts the user group information of calling user A in the SIP INVITE request, such as inserting SIP in the P-Asserted-Identity header field: userA@chinatelecom.com, groupid=2222; The group identifier of the calling user A is 2222; the method for the session control unit to obtain the user group information of the calling user A can be obtai...

Abstract

The invention discloses a device of packet business network and a method thereof. The device consists of a session control unit and a business control unit. The session control unit connects a user-group through an SIP protocol; and sends the information of the user-group to the business control unit through the SIP protocol; group business processing is carried out by the business control unit according to the information of the user-group. The invention can realize the group business on an NGN.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a packet service method and network equipment. Background technique [0002] With the continuous maturity of packet technology, the traditional telecommunication network based on circuit switching is developing towards the broadband telecommunication network based on packet switching, and the use of Session Initiation Protocol (SIP, Session Initiation Protocol) as the call control signaling of the core network of packet telecommunication is currently One of the technological development trends, such as the research on the next generation network (NGN, NextGenteration Network) by standard organizations such as the International Telecommunication Union Telecommunication Standardization Sector (ITU-T, International Telecommunication Union-Telecom Standardization) and ETSI, these two standard organizations are currently The IP Multimedia Subsystem (IMS, IP Multimedia Subsystem)...
