Problems solved by technology

[0004] 1. IMS services can only be used under the condition of IP access, and IMS users cannot be online in real time to experience IMS services in real time
[0005] 2. When the user leaves the IP access conditions, other users cannot call the user
For example: when the user leaves the SIP phone, the user cannot answer the call initiated to the SIP phone
[0006] 3. The user can install the IMS PC client on the mobile phone to provide IP access and bearer for the mobile PC client to access the IMS network in the mobile PS domain, but the service quality of the mobile network PS domain is difficult to meet the voice and video services requirements
At the same time, if the user wants to keep the registration status, he must always be in the PDP activation status, which will occupy a large amount of network resources and consume the power of the mobile phone.

Embodiment 1

[0032] figure 1 It is a flow chart of Embodiment 1 of the method for using IMS services according to the present invention, such as figure 1 As shown, this embodiment includes:

[0033] Step S102: after the mobile terminal user completes the IMSI attachment in the CS domain, notify the IMS access device;

[0034] Step S104: The IMS access device registers with the IMS network on behalf of the IMS user bound to the mobile terminal user;

[0035] Step S106: the mobile terminal user uses the IMS service through the IMS access device.

[0036] This embodiment provides the use of IMS services through the CS domain of the mobile network, adding IMS access devices in the existing network, maintaining mobile phone users and the corresponding IMS users of the mobile phone users (hereinafter also referred to as proxied IMS users) After the mobile phone user is attached to the IMSI in the CS domain, the IMS access device registers the IMS user to the IMS network on behalf of the IMS u...

Embodiment 2

[0039] figure 2 It is a schematic diagram of Embodiment 1 of a system using IMS services according to the present invention. like figure 2 As shown, it includes the CS domain of the mobile network, such as the wireless access network, MSC, HLR, and PLMN network; and the IMS network and an IMS access device that realizes the intercommunication between the CS domain and the IMS network, namely figure 2 The IMS access gateway in .

[0040] The IMS access gateway is the core network element of the system. After a mobile terminal user (such as a mobile phone user) attaches to the IMSI in the CS domain, the IMS access gateway registers the IMS user bound to the mobile terminal user to the IMS network on behalf of the mobile terminal user, and is responsible for the CS domain Interworking between the user plane and the control plane between the domain and the IMS network. The IMS access gateway internally maintains the binding relationship between the mobile phone user and the ...

Embodiment 3

[0047] image 3 It is a schematic diagram of Embodiment 2 of a system using IMS services according to the present invention. This embodiment integrates the structure of the existing network, and clearly distinguishes the added equipment and functions to be realized in the present invention on the basis of the existing network.

[0048] Figure 8 It is a schematic diagram of the existing IMS network structure, such as Figure 8 As shown, the CS domain and the IMS network in the live network can be interconnected, as shown in Figure 8 :

[0049] Breakout Gateway Call Function (BGCF for short): used to select the egress PSTN (or CS domain) network. If the BGCF can determine that the outgoing public switched telephone network PSTN (or CS domain) network is located in the same network as it, the BGCF will select a Media Gateway Control Function entity (MGCF for short) that is responsible for intercommunication with the PSTN (or CS domain) ). When BGCF chooses to connect with ...

Abstract

The invention discloses a method and a system for using an Internet protocol (IP) multimedia subsystem (IMS), and equipment. The method comprises that: after finishing the attachment of international mobile subscriber identity in a circuit switched (CS) domain, a mobile terminal subscriber informs the IMS access equipment; the IMS access equipment registers an IMS subscriber bound with the mobile terminal subscriber to an IMS network as a proxy; and the mobile terminal subscriber uses an IMS service by the IMS access equipment. In the method, the equipment and the system, the IMS service can be used by the CS domain without installing a client, requiring the subscriber to keep a registration state all the time and occupying a great number of network resources, the IMS subscriber can online use the service in real time, various requirements of the IMS service can be simultaneously met, and the shortcomings of use of the IMS service through IP access in the prior art are overcome.

Description

technical field [0001] The present invention relates to data service technology in the field of communication, in particular to a method, device and system for using IP Multimedia System (IP Multimedia Subsystem, IMS for short) service. Background technique [0002] Existing technical solutions provide a way to use IMS services through IMS terminals, that is, through Session Initiation Protocol (Session Initiation Protocol, SIP for short) terminals, PC clients, Integrated Access Devices (Integrated Access Device, IAD for short) and other terminal ways through The IP network registers with the IMS core network and uses the IMS service. [0003] In the course of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] 1. IMS services can only be used under the condition of IP access, and IMS users cannot be online in real time to experience IMS services in real time. [0005] 2. When the user leaves the IP ...
