Description

The method of multi-interface registration

Technical field

The present invention relates generally to comprise the communication network field in IMS territory.More particularly, in the IMS territory the present invention relates to mobile network, register the technology of many contact user device.

Background technology

Mobile network is current just from pure circuit-switched network to IP-based network Development, therefore can seamless integration in existing IP-based infrastructure, for example, internet, World Wide Web (WWW) and other IP-based communication network.

In modern 3g mobile network, dividing circuit exchange (CS) territory and packet switching (PS) are overseas, and the flexible service delivery platform architecture for IP multimedia service is provided is appointed as by third generation partner program (3GPP) in IP Multimedia System (IMS) territory.A chief component in IMS territory is carry out the session setting of IMS session and stop the CSCF (CSCF) of controlling.Although proxy CSCF (P-CSCF) stops session path at IMS territory boundary, master control function is positioned at serving CSCF (S-CSCF).

For session control and signaling capability, as session initiation, session modification and session termination for IP-based voice call (VoIP) or multimedia conferencing, IMS uses session initiation protocol (SIP).SIP provides and is similar to the expect someone's call service of agreement such as ISUP (ISDN User Part), but in IP context.In SIP framework, termination is user agent (user agent) to an important logical entity of user's SIP session.User agent starts session request and its destination normally.

After user agent registers in IMS territory, user agent represents particular user contact.A certainly registrable more than contact of user, each contact is generally corresponding to a particular user device, and can connecting subscribers participating through this device.Due to the user capability that exists period of registration user agent to provide and q value (priority value), therefore, from multiple registration contacts, select the mechanism of a contact to utilize contact attribute.In the time can identifying the contact with limit priority, by S-CSCF, session request is forwarded to corresponding P-CSCF.Exist in the situation of two same grade contacts, enter session and be branched (fork), that is, be forwarded to two contacts, this causes conventionally at two user's sets line ringing.

In described up to now framework, because actual conditions are often no longer to have one-to-one relationship now between user's set (supposing near hardware user) and user agent's (being generally the software module that represents calling or session termination function), thereby produce a specific question.In the time using modern many contact user device, user may register a more than user agent now in network, so that two or more contacts can be associated with same user's set.This is for example different for GSM network, and in GSM network, the terminating point of calling is the user's set that is built-in with regularly required function.

For the service that realizes high efficient and flexible provides, generally preferably Service controll is placed in to IMS territory in the future, be also like this to the service being provided by other territory up to now.For example, the calling of typical voice service and Service controll are carried out by CS territory up to now.But the calling of these services and Service controll are placed in IMS territory by the network configuration plan of expection.Subsequently, user for example may have IMS client and CS client on its device.Now, two clients all need a user agent, that is, have two user agents to be associated with same user's set.The in the situation that of identical or overlapping user capability, S-CSCF thereby be branched off into two or more user agents that are associated with same user's set by entering communication request, thus may cause user's set to occur indefinite mode of operation.In addition,, under such as the condition such as " user cannot connect " or " user is busy ", redirection mechanism may cause entering calling to be redirected to another user agent but to be actually same device.

On same user's set, there are two or more IMS clients, or configured its IMS client from CS territory can be connected in the situation that or other configuration still having, similarly problem can occur user.

Therefore, the object of the invention is to propose a kind of high efficient and reliable mechanism that prevents above-mentioned undesirable effect.

Summary of the invention

According to first aspect present invention, propose a kind of two or more user agents that registration is associated with single many contact user device in IMS enables network method.Method comprises that by two each device identification (ID) that provide of user agent, to IMS territory, this device ID identifies user's set.

Term " user agent " is not limited to corresponding SIP entity while use in this article, represent can be user but summarize, and is the assembly that user's set or subscription client are taken over task or rather, and therefore can the configuration of user's ad hoc fashion.In this context, user agent for example can serve as the promoter of communication request, or serves as the destination of communication request.

Many contact user device are to provide two or more contact options to speech, data or multimedia communication are set or the accessibility device so that this type of is communicated by letter.In the present context, many contact user device generally will be associated with more than one user agent.

The user agent of multi-interface can be configured to the S-CSCF in IMS territory set of contact attributes is provided.Device ID can form new argument, or can be by the existing Parametric Representation among this set of contact attributes.IMS has enabled network and has preferably included the mobile network with IMS territory, but also can comprise other situation, for example, uses and is connected to WLAN, the WIFI in IMS territory or the access network of WiMAX.

One or more user agents can be arranged in user's set.For example, user's set can be taken over the SIP client for mediaphone or other application.Alternative or in addition, one or more user agents can be arranged near network (for example, reside in P-CSCF place, it or associated with it).In this case, user agent can serve as the CS client in user's set.Therefore, any communication will (for example only rely on CS agreement between the resident network node of CS client and user agent on user's set, 3GPP TS 24.008), and may be based on SIP between other entity (particularly P-CSCF and S-CSCF) in user agent and IMS territory.

The present invention is not certainly limited to SIP and uses.Exist for controlling with other agreement of signaling object in IP-based service field, or may exist in the future; An example is the existing H.323 agreement that ITU-T specifies.

In another modification, user agent provides the predesignated subscriber's ability value that is applicable to carrying through described IMS territory CS service in addition.Typical value may be " mediaphone, only for audio frequency ".This value is used for can being scheduled in existing autotelic situation in user agent's specialized designs, or can be controlled by user or operator.

Device ID can obtain from the global permanent identifier being associated with user's set.In one embodiment of the invention, can use IMEI (International Mobile Equipment Identity code).But, also may be for this object is used another global permanent identifier, as IMSI (international mobile subscriber identity code).

According to another aspect of the invention, propose to have enabled the method for network central control system for the communication request of many contact user device at IMS.Method is included as same user's set registers multiple user agents' step, wherein provides from each user agent the contact details that comprise the device ID that identifies user's set; And comprise that processing guides to the step of the communication request of user's set.Treatment step comprises following sub-step: identification is applicable to the multiple same apparatus IDs of termination to the registered contact of the communication of user's set; And according to the predetermined process scheme relevant with the detection of same apparatus ID, dispose communication request.

The device ID that is provided to S-CSCF or similar network node at user agent's period of registration allows to detect ahead of time undesirable situation, for example, and branch or be redirected and enter session to actual same user's set.Generally, for example, in the time that previous steps (, assessment user capability or q value) produces a more than contact possibility, application is for the detection routine of same apparatus ID possibly.

Predetermined process scheme can comprise communication request is only forwarded to the instruction that comprises one of contact of same apparatus ID.This may be the random contact of selecting contact to be detected from two or more with same apparatus ID, or can apply more detailed decision logic (for example comprising other parameter of contact profile).In addition, or alternative, and predetermined process scheme can comprise the instruction that is not redirected " doing " communication between the contact that comprises same apparatus ID.

In another modification, predetermined process scheme can be by one of at least configuration of Virtual network operator and user.For example, operator can standard mode configuration detection has the characteristic of same apparatus ID, and user can change according to its individual demand (being for example, particular value by adjusting q value).

The present invention can be used as hardware, software or its combination and realizes.Aspect software, propose a kind of computer program, it comprises the program code part of carrying out said method step when computer program moves on one or more calculation elements.Computer program can be stored on computer-readable recording medium.

According to another aspect of the invention, propose a kind of user agent, it serves as the terminating point of having enabled the communication of network from IMS.User agent is applicable to IMS territory period of registration generator ID, and this device ID identifies the user's set being associated with user agent.User agent will be generally one section of software can Java programming language writing, and except other, this language is welcome aspect the characteristic realizing in mobile phone.Certainly, user agent also can be based on hardware, or can be used as firmware and realize.

User agent is also applicable to the predesignated subscriber's ability that is applicable to carrying through ISM territory CS service providing to IMS territory period of registration.For custom-designed user agent, user agent in network and the agency that realizes on user's set for ease of understanding the present invention, this is particularly useful to simplification device configuration.

According to another aspect of the invention, propose a kind of user's set, combine user agent as above.For example, mobile device (phone, notebook, but conventionally also refer to itself not personal computer or other calculation element of " movement ") may realize the IMS client that comprises user agent, to allow the session in the IMS territory of setting and mobile or non-moving network.Session can be through WCDMA, GPRS, WLAN or WiMax transmission.In any case, user agent will provide its contact attribute that comprises device ID to IMS territory.

Also have according to the present invention on the other hand, proposed a kind of user's set, have as mentioned above, user agent associated with it, user agent is arranged in network.Herein, user's set and user agent separate physically, and agency is depended on the details of situation with the communication protocol between installing.User's set for example can be in conjunction with CS client, and user agent serves as CS client subsequently.In this case, the responsible agreement based on CS of for example specifying in TS 24.008 of communicating by letter between user agent and user.

User's set can make other user agent and its combination and/or associated with it.Example comprises having that SIP has enabled IMS client and SIP has enabled the device of CS client, or for example has one through WCDMA work, and another is through the device of two IMS clients of WLAN work.

According to another aspect of the invention, propose a kind of network gateway, for carrying out exchanges data combining between the user's set of CS client and the IMS territory of network, this CS client is applicable to carry out exchanges data with the CS territory of described or any network, and gateway is in conjunction with user agent as above.This gateway allows user to access by CS, the service from common CS phone access IMS territory.In CS phone, serve (being generally SIP) user agent of CS client except taking over, gateway can be carried out following one or more function: at TS 24.008/ISUP and for the interworking between the SIP of call/session; At least function subset of P-CSCF; For the gsmSCF (GSM Service controll function) of static call routing; And media gateway (MGW) is controlled.Gateway can be provided as self-contained unit, or it can be with MSC in same position.

The another aspect also having according to the present invention, has proposed in IMS enables network the service node of the communication request for controlling many contact user device.Service node is applicable to register multiple user agents for same user's set, wherein provides from each user agent the contact details that comprise the device ID that identifies user's set.Service node is also applicable to process the communication request of guiding to user's set.Processing comprises the following steps: identification is applicable to the multiple same apparatus IDs of termination to the registered contact of the communication of user's set.Process further comprising the steps of: according to the predetermined process scheme relevant with the detection of same apparatus ID, dispose described communication request.Service node can be for example the S-CSCF in mobile network IMS territory.

Embodiment

In the following description, for ease of explaining instead of restriction, stated specific details, as specific network topology, communication protocol etc., to detailed understanding of the present invention is provided.It will be apparent to one skilled in the art that in other embodiment that departs from these specific detail and can put into practice the present invention.For example, technical staff will understand, by putting into practice the present invention from following signaling and the control protocol that illustrates that SIP standard of the present invention is different.In addition, can put into practice the present invention by the various access networks that are different from following PS and CS access.

Those skilled in the art also will understand, described function can be by being used independent hardware circuit below herein, use the software in conjunction with programming microprocessor or all-purpose computer operation, use application-specific integrated circuit (ASIC) (ASIC) and/or use one or more digital signal processors (DSP) to realize.Also will understand, although the present invention is described as a kind of method, it is implemented in also can and being coupled to the memory of processor at computer processor, and wherein, memory coding has one or more programs of carrying out methods described herein.

With reference to Fig. 1, flow process Figure 100 illustrates the step of the present invention's the first embodiment of the method, that is, and and two or more user agents that registration is associated with single many contact user device in IMS enables network.

In first step 102, each user agent sends a device ID to IMS territory.Device ID identifies the user's set being associated with user agent uniquely.In second step 104, in IMS territory, receive corresponding device ID.Like this, each user agent at period of registration to IS territory generator ID.

With reference to Fig. 2, flow process Figure 200 illustrates the step of the present invention's the second embodiment of the method, that is, be many contact user device control communication request in IMS enables network.

In first step 202, registered user agency in network.In other step 204,206, in network, register other user agent.Step 204 clearly do not illustrate, and may comprise the agency of registration in step 202 and 206 and register zero or more user agents.At period of registration, each user agent provides the contact details that comprise the device ID that identifies user's set.

In other step 208,210, process the communication request of guiding to user's set.Step 208 comprises that identification (or detection) is applicable to the multiple same apparatus IDs of termination to the registered contact of the communication request of user's set.Step 210 comprises according to the predetermined process scheme relevant with the detection of two or more same apparatus ID, disposes communication request.

Fig. 3 illustrates the network entity that comprises user's set schematically, has related to these entities in another embodiment of the present invention.User's set (or user equipment (UE)) is used by user Bob.Device comprises the SIP client 312 of carrying out PS access for the IMS territory 311 to mobile network.SIP client (, sip user agent) be associated with the privately owned ID and the public ID " bob@op.com " that obtain from ISIM (IP multimedia service identity module), this public ID form resembles e-mail address, but can be also numeral (being similar to telephone number) or any other identifier.In addition, user agent has multiple contact attribute associated with it, and this will be discussed below.Contact profile is called " user Bob's contact A ".

User's set 310 also comprises the CS client 314 for the CS territory (not shown) communication by mobile network.In addition, CS client 314 can be connected to the entity 320 in mobile network, and this will describe subsequently.Being connected between client 314 and entity 320 is based on CS, that is, CS agreement will be used for arranging, and control and stop being connected.This agreement may comprise for being connected the ISUP of (connecting leg) along separate routes between radio access network and entity 320.

Entity 320 is media AGCF (MAGCF).Generally speaking, MAGCF320 carries out and is mainly used in registration and calls out the interworking about function.One of its task is to take over sip user agent 322,324 for different user device.CS client 314 in user agent 322 and user Bob's device 310 is communicated by letter, on the other hand, and as other entity communication in SIP client and IMS territory 311.User agent 322 has the associated with it value being obtained by IMSI and is used as privately owned ID.This is equally applicable to interim public ID.Alternative, privately owned ID and interim public ID can not obtain from IMSI, but otherwise generate.In this example, permanent public ID is identical with the public ID being associated with the interior user agent 312 of user's set 310.User agent 322 has multiple contact attribute associated with it, and this will be discussed below.Its contact profile is called " user Bob's contact B " to further discuss.

Except taking over user Bob's user agent 322, MAGCF 320 can be other user and takes over other a large amount of user agents; Two other user agents 324 have been summarized in demonstration.MAGCF also comprises the P-CSCF 326 as user agent 322,324 agency (Proxy).

IMS territory 311 also comprises independently proxy CSCF 330, and this agency is as the factorage of SIP client 312 on user's set 310.Another CSCF 340 is as user Bob's (and other possible user) service entities (S-CSCF) work.The session that S-CSCF 340 thereby control are relevant with corresponding user agent 312,322.IMS territory 311 can comprise the part of user's home network.

SIP client 312,322 will be registered (registering to S-CSCF 340 or rather) in IMS territory 311, to can start session request or so that the session request that other user starts can arrive.For this reason, in registration process, corresponding agency will provide respectively its contact profile (or briefly contact) A and B to S-CSCF 340, and S-CSCF is as shown in the object 342 of " Bob " by name, store contact with user (user) or the relevant mode of subscriber (subsriber).Certainly, many other users can register its user agent at S-CSCF 340 places, and this is designated as another object 344.

Object 342 " Bob " is shown in more detail structure for amplifying in Fig. 3, and some contents of this object 342 are shown schematically.Object has user Bob's privately owned user ID and public permanent and temporary transient user ID.In addition, object is included in contact A and the B (label 352,354) that period of registration is provided by user agent 312,322.

Contact A 352 specifies at one end by the parameter of the session that on user's set 310, SIP client 312 stops.Contact address can be WLAN or GPRS address.User capability is " with the mediaphone of video, audio frequency ".For priority or the q value of user agent's instruction are " SIP client WLAN ".CSCF 330 is designated as agency.

Contact B 354 is appointed as the address of network MAGCF 320.Because communication data will be by the transmission between CS client 314 on user agent 322 and user's set of CS access mechanism, therefore, " mediaphone, only for audio frequency " is designated as ability.Q value is correspondingly chosen as " CS client ".The CSCF 326 that is arranged in MAGCF 320 is designated as agency.

That understand that the present embodiment wants special concern is device ID356,358, and they have formed a part of each contact profile A, B, and are similarly also sent to S-CSCF 340 at period of registration from user agent 312,322.

The user's set 310 of demonstration hypothesis herein has IMEI associated with it (International Mobile Equipment Identity code).This is for example the situation that is applicable to mobile phone.IMEI is made up of the information and the sequence number that represent manufacturer, and is similarly formed in the past the ID that identifies uniquely user's set in all mobile phones of manufacturing (with manufacturing in the future).But for ease of understanding the present invention, device identification unique in the session control context relevant with the IMS territory of specific (movement) network will also be suitable for.

Therefore, in network, unique identifier also will be enough in principle.But relying on existing IMEI instead of introduce another identification schemes may be more efficient.For the device without IMEI, will use other mechanism.For example, for ease of understanding the present embodiment, also possibility user's IMSI (international mobile subscriber identity code).Because unique herein mark assigns to user, assign to or rather its (U) SIM card instead of directly assign to user's set, therefore, same user can use in same device or the several IMSIs associated with this device.But these situations seem there is no large association at present, and can be by suitably configure user agency and/or responsible IMS assembly are solved.

Certainly, for the purposes of the present invention, can use other global permanent identifier.In this regard, " whole world " refers to that the network being at least attached to respect to user's set is " unique ", and network is usually included in user or subscriber subscribes all cross-correlation entities under Virtual network operator control extremely, but other configuration is also possible.

In Fig. 3 example shown, the IMEI of user's set 310 by the user agent 312 who is positioned at device for obtaining device ID.Be arranged in the also from then on IMEI acquisition device ID of user agent 322 in IMS territory 311.Conventionally,, if two or all user agents obtain device ID by same approach, this will be favourable.For example, the simplest possibility is directly to use IMEI.In the situation that this does not meet needs, for example, owing to storing or processing capacity limit or due to security reason, can use the scheme of the hashed value that is for example similar to the data set that generation will be signed or encrypt in the field of IT safety.

User agent 322 in MAGCF 320 may through with CS client on user's set 310 based on the communicating by letter of CS, received IMEI, or device ID directly configures may realize user agent 322 by operator in MAGCF 320 time.

In the present embodiment, two user agents 312,322 all obtain device ID by same approach.Therefore, for each other, install ID356, the 358th, identical.Below with reference to Fig. 4, the use of conversation control function to such device ID described according to further embodiment of this invention.

Fig. 4 illustrates mobile network 400 schematically, wherein, IMS territory (may be identical with the IMS territory 311 in Fig. 3) by serving as the CSCF 402 of serving CSCF, with service MSC at the MAGCF 404 of same position and IMS application server and MRFC (Multimedia Resource Function control) 406 expressions.Mobile network 400 also comprises the user data transmission ability (UTRAN/GERAN) being represented by MRFP (Multimedia resource function processor (MRFP)) 412, media gateway 414 and the radio access network (RAN) for UMTS/GPRS 408.The path that user data is specified along label 420 forwards, and signaling/control data forward along path 416,418.

Suppose that user's set 410 is same as shown in Figure 3 herein, belong to user Bob.Corresponding user agent 411 is arranged in the MAGCF 404 being associated with user's set 410.User agent 411 is as shown in (TS) 24.008, through the communication protocol based on CS, with the CS client (not shown) of user's set 410 and other subsystem communication of device 410.For the IMS territory of network 400, SIP is as control protocol, to for example act on behalf of 411 S-CSCF 402 registered users of place.

The calling of conventionally, drawing oriented users Bob (guiding or rather to the user agent who is associated with user Bob's user's set 410) will be routed to S-CSCF 402.S-CSCF 402 will relate to IMS AS 406, and IMS AS will trigger executive termination service.S-CSCF 402 knows the address of the MAGCF 404 of service-user device 410.MAGCF 404 also comprises P-CSCF (not shown), and this P-CSCF is the P-CSCF specifying in user agent 411 contact profile.

In the situation that having multiple (activity) registration, in S-CSCF 402, need to judge which P-CSCF enters session request will be forwarded to.Herein hypothesis enter call out need user capability " audio frequency ' and (speech, voice), this by " with the mediaphone of video, audio frequency " and " mediaphone, only for audio frequency " meet.The Fig. 3 with these abilities contacts A and contacts B and therefore all meets the condition that forwards the request to the corresponding P-CSCF in its address.

S-CSCF 402 generally will check the q value of each contact A and B, and selects to have the contact of the highest q value.In the situation that contact has identical q value, according to prior art, can apply branch's (and line ringing).If as in the present embodiment, two contacts are associated with same user's set, and branch will can correctly not work.

According to the present embodiment, therefore S-CSCF 402 will check the device ID comprising in two qualified (qualifying) contact in addition.From Fig. 3, obviously can see that auto levelizer ID is identical.In this situation, in S-CSCF 402, need other logic to for example request be only forwarded to one of these contacts and/or avoid, when " user is busy ", session is redirected to another contact (because two contacts represent same device) from a contact.

Contact attribute " device ID " can be essential or optional attribute, for example, to allow parallel (routine) SIP client that uses enabled SIP client and do not enable as generator ID in network.In optional situation, S-CSCF will process registered user and act on behalf of the not situation of generator ID.A possibility is to suppose subsequently to meet without the contact of device ID the qualification of not doing to further consider, or it meets the qualification that will further consider.

In arbitrary situation, in last step, S-CSCF has the list containing two or more contacts, all meets the condition that communication (session) is asked and comprised identical device ID (or the in the situation that of device ID disappearance, be assumed to be and have same apparatus ID) that forwards.In described embodiment, this is the situation of contact A and B herein.Therefore S-CSCF 402 will judge in these contacts which is for Forward-reques.

This judgement will be based on pre-defined rule or processing scheme.In many situations, come in handy be processing scheme comprise by communication or session request be only forwarded to the instruction that comprises one of contact of same apparatus ID.Decision request will be forwarded to the responsible further inspection to contact attribute of which qualified contact, at S-CSCF place other user data available or associated with it, or can be simply by selecting " Section 1 " in contact list complete.In any of these cases, all realize advantage of the present invention, that is, avoided session to be undesirably branched off into same physical unit.

In described example, therefore S-CSCF 402 may determine to use the attribute of contact A herein, and this causes only through the P-CSCF in MAGCF 404, request being forwarded to user agent 411.Suppressed to the forwarding that is arranged in the upper user agent of mobile phone 410 (Fig. 4 is not shown) through another P-CSCF.Voice data will forward through transmission node 412,414 subsequently.

In session or call out and be routed to after the P-CSCF that MAGCF 404 comprises, MAGCF 404 will stop to the calling of user's set 410 and without calling any service.

In S-CSCF 402, judge that the predetermined process scheme using for the qualified contact of same apparatus can be included in addition or alternatively busy and communication do not comprised to instruction redirected between the contact of same apparatus ID.This has been avoided being temporarily busy with making while for example answering another call for example notebook, smart phone or other mobile device ring user.

Above-mentioned predetermined process scheme can be configured by operator.For example, it can be applied according to class of subscriber, for example, and " common " user or " senior " user (in the situation that Virtual network operator determines this characteristic to be provided as optional attribute conventionally).Processing scheme also can be embodied as and can be configured by user, as session being transported to the situation of its user agent q value of preferred SIP contact.But, as due to physics bandwidth restricted, generally to avoid the same by the unnecessary transfer of data of radio interface transport, the configuration based on operator is seemingly preferred conventionally.Therefore, the mode that operator may prefer the branch that avoids unnecessary configures radio access, and does not give customer impact possibility in this respect.But some other or optional sub-features relevant with service characteristic may be also configurable for user, for example, when " hurrying ", be redirected.

Although the described contact of having supposed for two registrations of same device above, the present invention is equally also applicable to have for same device other situation of a more than registration certainly.For example, may there be three user agents to be associated with mobile phone, the CS client on an agency service phone, an agency is for the PS access through WLAN, and an agency is for honeycomb PS access.Some or all of these user agents can have the registration for mediaphone in IMS territory.In other situation, PS access can be used for acquiring the access in mobile network CS territory.In this situation, user's set can arrive through CS and two kinds of accesses of PS from CS territory simultaneously.Technical staff is clear, and many other situations are possible.

In foregoing, invention disclosed allows IMS to enable network and stops the communication request of guiding to user's set in clear and definite mode, even if be also like this for there is the situation of multiple registrations relevant with Same Physical user's set in IMS territory.

Although the present invention is described with respect to its preferred embodiment, be appreciated that this disclosure is just for explanation.Therefore, the present invention's restriction of claims scope of only being enclosed.
