Technical field

The present invention relates to wireless communication field, relate in particular to the interconnecting method between (Presence) system of a kind of dissimilar existence, and a kind of interlink server that uses in the method.

Background technology

The technical field that the present invention relates to be on mobile communications network, carry out have (Presence) business, the mobile network comprises existing 2G, 2.5G, following 3G and IMS multimedia subsystem etc.

Presence information comprises availability (for example: in machine open/close information, the call state), User Status (for example idle, not idle, meeting in), the positional information of client device, the ability (for example to voice, text, GRPS, multimedia support situation) and the searchable user profile of client device, for example: user's mood (happiness, anger etc.), user's hobby (football, fishing, calculating, dancing etc.).Because user's presence information is personalized, so should be able to support whether externally disclose these information according to user's requirement decision.

The user can subscribe to other user's presence information, subscribe to successfully after, when corresponding presence information changes, can notify the subscriber.The user can obtain favorable user experience by subscribing to other users' presence information.Certainly, when the user does not need other users' of having been subscribed to presence information, can realize by the operation that cancels subscriptions.The user can also obtain other users' current presence information, obtains the situation that operation relatively is applicable to checking of occasional nature and uses other users' presence information.

The standard about presence service has two big classes in OMA International Standards Organization now, and a class is based on the instant message and the Presence (WV IMPS) of radio countryside protocol, mainly is applicable to conventional communication networks; One class is based on the Presence of SIP/SIMPLE agreement, mainly is applicable to the next generation network based on IP multimedia subsystem (IMS).

The Presence at initial stage is and instant message (Instant Message, IM) bundling together, playing OMA in 2002 just begins one's study and formulates the IMPS business norms, the basic service functional entity of IMPS has 4: Instant Message, Presence, group management (Group Management), shared content (Share Content), wherein Instant Message and Presence are integrated in the IMPS server jointly as two important business function entities, and the two is in conjunction with tight.

Under the IMS network, the basis session protocol is initial session protocol (SIP), SIP instant message and Presence expansion (SIMPLE) are to be the Extended Protocol that IM and Presence do on the SIP basis, presence service under the IMS network also claims SIMPLE Presence, at this moment presence service as a basic business engine (Enabler) by independent, it can (Push to talk on Cellular, POC) business waits other multiple business that the ability support of Presence is provided for IM business, PTT business.The SIMPLE presence server by SIP/IP core network (SIP/IP CORE) can with other application servers (AS) entity in the IMS network, for example SIMPLE IM server, POC server communicate.

For final use user, these two kinds of agreements should be transparent, also are that the user answers imperceptible otherness when using presence service, and no matter he is IMPS user, or SIMPLE is Presence user.From user's use angle, presence information that should be able to any type of user of seamless application.

In the existing P resence system, the user can only use the presence information with other users of own same type immediate news systems, for example subscribe to, obtain, and can not use presence information with other users of own different type immediate news systems.
