Technical field

This paper describes theme and relates to the method and system that is used for providing at communication network the unified resource maps identifiers.Specifically, this paper describes theme and relates to method, system and the computer program that is used to provide universal uniform resource identifier symbol (UURI).

Background technology

Raising along with popularization, use and the ability of computer, computer network, internet, telephone network and telecommunication system, discern the user of these systems and network by the identifier of continuous increased number, and get in touch the user of these systems and network via the identifier of continuous increased number.The user must not only preserve and/or remember user's home phone number, cell phone number, e-mail address, instant message transfer address, homepage etc. usually, and preserves and/or remember that kinsfolk, friend, social activity and commercial affairs know each other people's etc. home phone number, cell phone number, e-mail address, instant message transfer address, homepage etc.In addition, along with diverse network and system merge and fusion, user expectation is communicated by letter with other mode of technical area with historical between spanning network.

For example, third generation partner plan (3GPP) has defined Internet protocol (IP) IP multimedia subsystem, IMS (IMS) network as new mobile network infrastructure, and it makes it possible to fused data, voice and mobile network's technology on IP-based foundation structure.The IMS bridge joint gap between existing traditional electrical letter technology and technique of internet, allow Virtual network operator that standardized, reusable platform is provided, this platform can be used for providing service to mobile network and road communicating line network simultaneously, and the unique combination of service is provided pellucidly to the terminal use.

The major function of IMS is to set up media communication session between the user and the user with between using.IMS uses Session Initiation Protocol to initiate, revise and termination relates to the interactive user session of multimedia key element (such as video, voice, instant message transmission, game on line and the virtual fact), and dynamically revises the ability of session (for example adding video component to existing voice conversation) to service and " being in operation " that the service person of foundation is provided for making up in the same session.As a result, new and user novelty become and can obtain to user and multi-user's service, and such as the voice service, visual telephone, chat, PoC and the multimedia conferencing that strengthen, they are all based on the thought of Multimedia session.Therefore, for example, IMS user may want to the cell phone send Email, perhaps uses a computer and carries out call, and this only is two examples of boundary between fuzzy former phone of making a clear distinction between good and evil and can not be compatible and the data set network.

But even for the network that merges, some shortcomings and inconvenience are arranged still, they are shortcomings and inconvenience of leaving over when phone and computer network are discrete entity.A kind of such shortcoming is to continue and need preserve a plurality of contact details (for example telephone number, cell phone number, e-mail address, instant message address etc.) for everyone in user's contact list.For example, user A can not be to user B send Email, unless A knows the e-mail address of B.In other words, even A knows the every other contact details of B, such as telephone number, cell phone number, instant message address etc., A can not be to the B send Email.

Consider that user B uses the situation of the mobile phone that can receive Email: from the viewpoint of networking, audio call and Email will arrive same destination---mobile phone of user B---and even can reach same destination by network through same path.Under current condition, A can call out B (because A knows the telephone number of B), but A can not be to B send Email (because A know the e-mail address of B), even the destination of message is identical.

Therefore, consider aforesaid shortcoming, for the user on the integration networks, needing to provide URI identifier single, that remember easily to other users, described URI can be used for any communication pattern (for example voice, Email, message transmission, multimedia etc.) convenient and IMS user, described integration networks such as Session Initiation Protocol network, next generation network (NGN) or IMS network.Specifically, exist demand for such system and method, described system and method is used to allow universal uniform resource identifier symbol (URI) or UURI to be associated with the user so that all communication can be the address with UURI all, no matter and communication pattern how.

In frame 100, receive message, described message comprises the UURI that is associated with the user, and comprises the media type indicator that is used to indicate medium type.For example, in internet protocol multimedia subsystem (IMS) network, can receive Session Initiation Protocol message from attempting to carry out the user that network voice (VOIP) calls out, for example SIP INVITE (SIP invitation) message.Following table 1 shows exemplary sip message form.

Table 1-example sip message form

In sip message, exist several can comprise the position of UURI.For example, the UURI that is associated with the user can be included in SIP begin column " request URI " field, the general head of SIP " extremely: " field and/or the general head of SIP " the certainly: " field.

In sip message, exist several can comprise the position of medium type.For example, can in the general head of SIP " content type " field, comprise media type indicator.If source body is many purposes the Internet mail extension (MIME) form, then can in MIME " content type " head, find media type indicator.For example, the voice mail of MIME coding can have MIME head " content type: audio frequency/mpeg ".If source body is Session Description Protocol (SDP) form, then can in SDP media description section, find media type indicator.For example, video flowing can have SDP media descriptor handling " medium=video ".

It is that the limit of possible position of UURI or medium type is enumerated that above-mentioned example is not intended to; UURI and/or medium type can be included in other parts of sip message, perhaps are included in the message of other types.

In frame 102, discern URI based on the UURI that is associated with the user and based on media type indicator.In one embodiment, can use all following forms of table 2 that shows that UURI and medium type are mapped to URI according to the embodiment that this paper describes theme.

Table 2-UURI analytical capabilities table

??UURI	Medium type	Be resolved to URI
			??user@Tekelec.com	Image	??sip：userPic@vzw.com
??user@Tekelec.com	Text	??sip：userIM@vzw.com
			??user@Tekelec.com	Video	??sip：userMovie@vzw.com
??user@Tekelec.com	Message	??mailto：userSMS@vzw.com
			??user@Tekelec.com	Audio frequency	??sip：userVOIP@vzw.com
??user@Tekelec.com	Audio frequency	??tel：9194605555

In frame 104, send the message that comprises the URI that is discerned.Referring to top table 2, can UURI " user@Tekelec.com " be resolved to a plurality of different URI according to medium type as can be seen.

In one example, the text message such as Short Message Service (SMS) message is sent to " user@Tekelec.com ".UURI with resolved be " sip:userIM@vzw.com ", and described SMS message will be sent in the service of the user's of " userIM@vzw.com " instant message (IM).

In another example, send picture to " user@Tekelec.com ".UURI with resolved be " sip:userPic@vzw.com ", and view data will be sent to for example user's handheld personal digital assistants.

Last column in the table 2 can be used as acquiescence or reserve situation, if in time, use under the situation of any list item in its medium type unmatch list 2 that comprises in message for example or when the URI in the described table does not respond---this can be if user's VOIP connects the situation of off-line---, in this case, audio message should be sent to user's routine call or voice mail account.

Fig. 2 is the block diagram explanation embodiment that describes theme according to this paper, that universal uniform resource identifier symbol (UURI) is mapped to the example system of unified resource identifier (URI).Referring to Fig. 2, described system can comprise the general URI analytical capabilities URF 200 that is used to resolve universal uniform resource identifier symbol (UURI), and described universal uniform resource identifier symbol (UURI) is associated with the user and comprises the media type indicator that is used to indicate medium type.URF 200 can discern unified resource identifier (URI) based on UURI and media type indicator, and sends the message that comprises the URI that is discerned.

For example, CSCF CSCF 202 can receive the message such as SIP INVITE (Fig. 2, message 1).Described message can comprise UURI.For example, UURI can be the part of SIP " request URI " field or SIP " extremely: " field.Sip message can also comprise media type indicator, such as SIP " content type " field.In message 1, request URI: and extremely: field comprises same UURI " user@Tekelec.com ", and content type: field comprises string, and ' medium type=" audio frequency ", its indication medium type is an audio stream.

In one embodiment, as shown in Figure 2, CSCF 202 can send inquiry to URF 200, and receives response from URF 200.For example, invite (Fig. 2 in case receive SIP, message 1), CSCF 202 can detect and flow into message and comprise UURI (at request URI: in the field) and media type indicator (at content type: in the field), and send the URF query messages to URF 200, this URF query messages comprises the UURI that is associated with the user and comprises the media type indicator (Fig. 2, message 2) of indicating medium type.In case receive described message, URF 200 can resolve to suitable URI with UURI based on medium type.In one embodiment, URF 200 can use the form of for example going up table 2 to come executive table to search.URF 200 can beam back response message to CSCF 202, and described response message comprises URI and the media-type identifier (Fig. 2, message 3) that is associated with the user.CSCF 202 can replace with the UURI in origination message the URI that is returned by URF 200 subsequently, and sends the message (Fig. 2, message 4) that comprises the URI that is discerned to the destination of message.In this embodiment, URF 200 carries out query/response function: URF 200 and receives query messages from the query entity such as CSCF 202, carries out the UURI analytical capabilities, and beams back the response message that comprises the URI that is discerned to query entity.

In another embodiment, CSCF 202 can not adjusted or can not be detected SIP INVITE (Fig. 2 that UURI is being received, message 1) existence in, and can initiate the URF inquiry transaction (being similar to person as mentioned above) that is associated acquiescently.

Fig. 3 is theme is described in explanation according to this paper a block diagram another embodiment, that be used for universal uniform resource identifier symbol (UURI) is mapped to the example system of unified resource identifier (URI).In this embodiment, receive the message that comprises UURI and media type indicator as CSCF 202---such as SIP INVITE (Fig. 3, message 1)---time, CSCF 202 can be with described forwards to URF 200 (Fig. 3, message 2).In case receive the message that comprises the UURI that is associated with the user and comprise the media type indicator that is used to indicate medium type, URF 200 can discern URI based on the UURI that is associated with the user and based on media type indicator, send the message (Fig. 3, message 3) that comprises the URI that is discerned to the destination of message then.In this embodiment, URF 200 carries out message sink/modification/forwarding capability: URF 200 and receives message from the source entity such as CSCF 202, carry out the UURI analytical capabilities, and send the message that comprises the URI that is discerned to the destination entity different with source entity.The message that is sent to the destination entity can be brand-new message, and perhaps it can be identical with the message that is received, but UURI is replaced with the URI that is discerned.By this way, and compare, reduced Internet traffic at the embodiment shown in Fig. 2.

Figure 4 and 5 have illustrated the block diagram another embodiment, that be used for universal uniform resource identifier symbol (UURI) is mapped to the example system of unified resource identifier (URI) of describing theme according to this paper, and described system works together with the function that exists of the online property (availability) that is used for definite described UURI associated user.Fig. 4 has illustrated the exemplary behavior of described system when the user Ke Lian that is associated with UURI, and Fig. 5 has illustrated the exemplary behavior of described system when the user who is associated with UURI can not join.In order to illustrate, suppose that the user in this example has two kinds of phones: the VOIP phone, it is connected to the internet; And, another kind of phone, it is connected to traditional telephone network, such as the PSTN network.Also supposition, if current online (promptly being connected to the internet) of user then this user preference receives audio call on her VOIP phone, if the user would be current not online then this user preference receives audio call on her another phone.

Fig. 4 has illustrated the exemplary behavior of described system when the user Ke Lian that is associated with UURI.In Fig. 4, CSCF 202 receives the message that comprises the UURI that is associated with the user and comprise the media type indicator that is used to indicate medium type, such as SIP INVITE (Fig. 4, message 1).In this example, SIP invites and indicates content type is " audio frequency ", and indicating described invitation is to set up voice conversation or audio call.

As the situation of message 2 among above-mentioned Fig. 2, CSCF 202 can send UURI analytical capabilities inquiry (Fig. 4, message 2) to URF 200.Again referring to top table 2, UURI " user@Tekelec.com " has two URI that are associated with medium type " audio frequency " as can be seen: first is to be used for " sip:userVOIP@vzw.com " that VOIP calls out, and second be " phone: 9194605500 " that is used for traditional telephony call.URF 200 can at first resolve UURI and medium type, and determines to use URI " userVOIP@vzw.com ".

URF 200 can determine the user's that is associated with URI existence subsequently.For example, URF200 can be to existing function 400 to send the message (Fig. 4, message 3) of asking such as the user.Exist function 400 can return the message of the current state that is used to indicate the user who is associated (Fig. 4, message 4).

In Fig. 4, described user can join; In this case, URF 200 can respond the URF inquiry with the message (Fig. 4, message 5) of the VOIP URI that comprises this user.CSCF 202 can replace with the UURI in the origination message VOIP URI subsequently, and sends the message (Fig. 4, message 6) of modification to the destination of described message.

Fig. 5 has illustrated the exemplary behavior of described system when the user who is associated with UURI can not join.In Fig. 5, described system for the operation of first three message and response be identical in the example described in Fig. 4; To not repeat its explanation at this.

But, in Fig. 5, exist function 400 to return the message (Fig. 5, message 4) that the user that is associated with URI of indication can not join.

Can not join in response to definite described user, URF 200 can determine can be that can obtain to substitute for specified medium type, reserve or the URI of acquiescence.For example, again referring to top Fig. 2, URF 200 can resolve to URI " phone: 9194605500 " with UURI and medium type, and responds the URF inquiry with the message (Fig. 5, message 5) of the PSTN that comprises the user or Mobile Directory Number.

CSCF 202 can replace with user's telephone number with the UURI in the origination message subsequently, and sends the message (Fig. 5, message 6) of modification to the destination of described message.

In alternate embodiment, can be by such as another network elements of SIP router, sip agent or other ISP nodes or another network elements types is carried out as mentioned above and the function carried out by CSCF 202 in Fig. 2-6.

Can understand, describe under the situation of scope of theme not breaking away from this paper, can change the various details that this paper describes theme.And above-mentioned explanation only is used for explanation, and is not used in restriction.
