Description
Technical field
The present invention relates to the communications field, be meant that specifically (Internet ProtocolMultimedia System IMS) is method, IP Multimedia System and multi-user's access device of the middle group registration of next generation network (NGN) of core with IP Multimedia System.
Background technology
IP Multimedia System (IMS) is 3rd Generation Partnership Project (3rd GenerationPartnership Project, be called for short 3GPP) definition, a brand-new framework, in the IMS framework, CSCF (Call Session Control Function, abbreviation CSCF) entity is the core functional entities of IMS, is mainly used in the calling and the session control that realize IMS.Three kinds of CSCF entities have been defined among the IMS: proxy call conversation control function entity (Proxy-CSCF, abbreviation P-CSCF), inquiry call conversation control function entity (Interrogating CSCF, be called for short I-CSCF) and service call session control function entity (Serving-CSCF is called for short S-CSCF); Wherein the major function of S-CSCF is to accept user's registration, downloads and interim storage user related data from home subscriber server (Home Subscriber Server is called for short HSS); Be redirected route, carry out call session control; Trigger user's signing service, cooperation service platform carries out business support etc.HSS entity among the IMS then mainly is responsible for storing user subscription information and positional information etc.
With IP Multimedia System (IMS) is an independence that characteristics are access devices of the next generation network (NGN) of core, allow to insert various types of terminal equipments, wherein there is a kind of equipment to be called multi-user's access device, this multi-user's access device can be with traditional user terminal (for example, common phone, Common Facsimile Machine) etc. be linked in the next generation network, common multi-user's access device comprises: SIP PBX (private branch exchange system of dialogue-based initiation protocol), SIP AG (IAD of dialogue-based initiation protocol) etc.Because traditional user terminal is not generally supported SIP (session initiation protocol) agreement, use multi-user's access device can act on behalf of the registration that traditional user terminal is finished IMS user, make traditional user terminal in next generation network, to initiate a session request, receive conversation request etc.
Multi-user's access device representative of consumer is initiated IMS user's registration, has solved conventional terminal and has inserted the problem of certain network down, but also drawn the too much problem of register requirement.When multi-user's access device powers up, can moment initiate numerous IMS user's register requirement, can bring big impact to the IMS core net.In addition, in use, multi-user's access device need replace legacy user terminals to send the refresh registration request, to guarantee the login state of conventional terminal in next generation network, this just means will produce at set intervals once registers storm, this normal operation for network is a huge impact, in order to solve the problem of registration storm, need the logon mode of multi-user's access device be improved.
In 3GPP TS 23.002 standards, mentioned the asterisk wildcard registration, this logon mode allows to use an asterisk wildcard to represent one group of user ID with similar features to register, and just means that after the asterisk wildcard registration this group user who meets feature succeeds in registration.This mode can significantly reduce the data of register requirement, one group of user with same characteristic features can only send register requirement one time, but this mode also has a restriction, require to use this group user of asterisk wildcard registration to have similar features exactly, for example, with the numbers of 13 beginnings etc., and in actual applications, the one group of user who needs group registration may be discrete fully, and therefore, the mode of asterisk wildcard registration can not satisfy the needs of using fully.
In addition, in 3GPP TS 23.002, mentioned the notion of implicitly registered set, one group of user ID of a user can be formed an implicitly registered set, as long as one of them user's registration, just think that other users that implicit registration is concentrated also register, as long as one of them user log off, other users that whole implicit registration is concentrated also nullify.This mode can be used to reduce the message count of registration, also can solve the problem of asterisk wildcard registration, but the group that registers often changes, for example, the user terminal of multi-user's access device removes from multi-user's access device, and this just need safeguard the content in the group, and the related network elements in the needs notice next generation network, so that the correct conversation request of finishing, and this part content is not described in existing 3GPP standard.
