Problems solved by technology

[0006] The inventor found the following problem in the process of realizing the present invention: when the user uses the IP address of the home network to perform IMS registration, the network side cannot make an accurate judgment on whether to allow the UE to perform the operation of the LBO service and notify the UE
At this time, when the UE needs to initiate a call request, it needs to attempt to initiate the LBO service. The attempt may fail, resulting in waste of resources and prolonging the call setup time.

Embodiment 1

[0032] Embodiment one, such as figure 1 As shown, a terminal registration method provided by an embodiment of the present invention may include the following steps:

[0033] Step 101: Receive a registration request, which carries terminal capability information;

[0034] The capability information of the above-mentioned terminal may be one or more of whether the terminal supports the use of different Internet Protocol (IP) addresses for media and signaling, whether the terminal supports local egress services, and the list of services supported by the terminal;

[0035] Step 102: judging whether the above-mentioned terminal can use the local egress service according to the above-mentioned terminal capability information;

[0036] The above-mentioned judging whether the terminal can use the local egress service according to the terminal capability information may be: judging whether the terminal supports the use of different IP addresses for media and signaling, whether the ter...

Embodiment 2

[0046] Embodiment two, such as figure 2 As shown, the embodiment of the present invention also provides a registration method under IMS. Of course, it is also possible to apply the method of embodiment 1 to other networks. The only difference is that the protocols and fields of the carried messages are different, so IMS should not be understood as limiting the scope of application of the embodiments of the present invention;

[0047] The English abbreviations that will be used in this embodiment include: Call Session Control Function (Call Session Control Function, CSCF), Home Subscriber Service (HSS), Interrogating Call Session Control Function (Interrogating-CSCF, I-CSCF), Proxy Call Session Control Function (Proxy-CSCF, P-CSCF), Serving Call Session Control Function (Serving-CSCF, S-CSCF)

[0048] Step 201: UE sends a registration request to P-CSCF. The registration request can carry the information required for UE registration, such as: public user ID, private user ID, ...

Embodiment 3

[0084] Embodiment three, such as image 3 As shown, the embodiment of the present invention also provides a network system, including:

[0085] The terminal 301 is used to send a registration request with the capability information of the terminal 301; receive the message of whether the terminal 301 can use the local egress service; determine whether the local egress service can be used, and if so, initiate a call request in the form of the local egress service;

[0086] The network device 302 is configured to receive a registration request with capability information of the terminal 301, and judge whether the terminal 301 can use the local egress service according to the capability information of the terminal 301; send a registration success message to the terminal 301; the above registration success message includes whether the terminal 301 can Information on using a local export business.

[0087] The terminal carries its own capability information in the registration requ...

Abstract

The embodiment of the invention discloses a registration method, a device and a system of a terminal. Taking the realization of the embodiment of the method as the example, the method comprises the following steps: a registration request sent by the terminal is received, and the registration request carries terminal ability information; the terminal ability information is used for judging if the terminal can use the local output service; the successful registration information is sent to the terminal; and the successful registration information includes the information about if the terminal can use the local output service. The embodiment of the invention has the following advantages that the terminal carries the self ability information in registration, a network side judges if the terminal can use the local output service and sends the judged result to the terminal, and the terminal does not need to launch the attempt of local output service, so the network resource is saved and the calling establishment time is reduced.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a terminal registration method, device and system. Background technique [0002] The Internet Protocol Multimedia Subsystem (IMS) is a subsystem superimposed on the Packet-Switched (PS) domain by The 3rd Generation Partnership Project (3GPP); IMS has a complete IP Core network functions, including session management, bearer control, etc. Its main functional entities include call session control function (CallSession Control Function, CSCF), home subscriber server (home subscriber Service, HSS), application server (Application Server, AS) and so on. [0003] Usually, when a user roams, both the user's control signaling and bearer data need to be routed back to the home network for processing. The media needs to be transmitted between the home network and the roaming network, which causes a waste of bandwidth between networks and is not conducive to optimal tra...
