Description
The application be application number be 200480044839.X, the applying date are December 3 in 2004 day, be called the dividing an application of application for a patent for invention of " realizing composite services in communication network ".
Technical field
The present invention relates generally to communication network field, especially relate to mobile communications network.The present invention relates to communication network more especially, and especially the user of mobile communications network enjoys composite services.
Background technology
Mobile telephone network is the mode that is similar to public switched telephone network (PSTN) (referred to as PSTN) at first, but is in order to realize voice communication, to build between mobile subscriber.Mobile telephone network and has experienced swift and violent development, especially introducing 2g mobile network, particularly such as those, meet GSM (" global system for mobile communications ") standard and meet the U.S. and the digital mobile network of the corresponding system that Japan adopts after.
Be similar to PSTN, 2g mobile network is also circuit-switched network; This has limited the bandwidth that can distribute to given user greatly, particularly in 2g mobile network.On the contrary, such as the data communication network of computer network, and internet has wherein adopted the packet switching arrangement that allows much higher message transmission rate.
In order to overcome the restriction such as the legacy circuit-switched mobile network of GSM net, make to allow the user of mobile terminal that the service providing by internet is provided in effective mode, some solutions have been proposed.One of the most universal scheme is GPRS (" general packet radio service ").GPRS is a kind of and digital mobile phone technology (in fact, it builds based on the existing GSM network architecture) GSM Web-compatible, and it allows data with the speed transmission higher than pure GSM was allowed.In fact, GPRS can be regarded as and is attached to the support on GSM and realized block data communication.Although the third generation wireless communication system that meets standard UMTS (" universal mobile telecommunications system ") such as those is more promising aspect data transmission bauds, GPRS is the solution improving in the realized solution of the data exchange capability in existing GSM network.
Except simple sound communication, the service that these mobile networks provide has all obtained increasing rapidly on quality and quantity; Only for some examples, sending and receiving short messages services recent years (" sending and receiving short messages system ", be called for short SMS) and Multimedia Message transmitting-receiving service (" Multimedia Message receive-transmit system ", or MMS), and Internet connection service has been accomplished to use.
Especially, the user who is mobile communications network, for providing multimedia service aspect, the communication between the user who only consists of voice there is strong interest, that is, and and thanks to exist increasing image, video, by the service of internet or the possibility by Email access data.In these services, so-called " composite services " have attracted the very big attention of mobile-phone carrier.For describing object of the present invention, " composite services " mean can open simultaneously and use two connections by the terminal of this communication for service network (not necessarily moving) conventionally, (packet switching PS) connects to be generally circuit (circuit switching or CS) connection and grouping.
U.Olsson and M.Nilsson are at Ericsson Review No.2, in 2003 article " Combinational services-The pragmatic first step toward all-IP ", described especially the example of a kind of so-called " composite services ", wherein used simultaneously and connected and be connected in grouping the ability of processing volume of services at circuit: at session, shared image.Author notices, simultaneously at circuit, connect and in grouping, be connected the possibility of processing traffic carrying capacity and not only allow with WCDMA (Wideband Code Division Multiple Access (WCDMA)), provided interface (the multi radio access bearer in " by aerial ", many RAB) in, use the possibility of a plurality of and parallel carrying, and permission and GSM, wherein standardized mechanism-duplex transmission pattern or DTM-obtain similar possibility.Yet in article, author notices that the only engineering feasibility of " successfully crossing aerial " is not enough.Sometimes forgotten common end user to the complicated of chnnel coding and radio wave propagation and lost interest in.Otherwise end user wants reliably, is easy to use and be well suited for the mobile terminal of current environment.In other words, some entities in mobile terminal it must be understood that user is attempting the thing of doing, and are converted into the sequence of operation.An example of describing in article relates to about a woman and her husband during the talk of a special horticultural show meeting.During session, this woman determines that the thing that she is being described shows her husband.Under perfect condition, it is simple that user interface (man-machine interface or MMI) should be enough, as with a kind of she only need to push button to open the mode of video camera.Mobile terminal should have enough intelligence and find how to arrive another participant of the calling on grouping connection and send image.According to author's description, in order to allow this occur, need following basic module:
Coordination function in mobile terminal (at least, the extended address book of the information of a getatability with relevant all coherent networks);
Getatability mechanism in grouping coupling part.According to author's description, long-term solution may, by based on IMS (IP Multimedia System), utilize SIP (session initiation protocol) session protocol to find other participants and to coordinate session parameter;
For the mechanism of assignment information acquisition capability, it allows the information based on the terminal use relevant reservation clever with network application, session status, bearer circuit state, user preferences etc.At this on the one hand, author advises that SIP is especially used http protocol and Web XML service.
By mobile terminal, enjoy in the other white paper that is described in Nokia company " Video sharing-Enrich your voice call with video " of service and provide, at internet website: openly can be used on http://www.nokia.com/BaseProject/Sites/NOKIA_MAIN_18022/CDA/Cat egories/Phones/Technologies/VideoSharing/_Content/_Stati c_Files/video_sharing_a4_2510.pdf downloading.
The real-time video of share service allows user can easily enrich their communication during telephone conversation.Always there is a user can share the live video of being taken by video camera or carry out the video clips of self terminal.Two users see identical video and can discuss to it in the audio call that continues them.In the described example of this white paper, Keith is connected in the normal call on (CS) in circuit with Malcom, and Keith wants to share live video with Malcom.They have and can share the device of video and register this service.Following flow process has been described in this white paper:
During ongoing CS audio call, Keith selects to share live video.
Keith confirms that Malcom is as recipient.
Malcom receives from the video request of Keith and accepts.
System is shown to this acceptance the Keith of the transmission that starts video flowing.
The device of Malcom starts the demonstration video identical with the device of Keith, and they can discuss by audio call.
When Keith shows that finishing video while being over the content that he wants to show shares, the audio call between Keith and Malcom keeps active state.
The technology that the video share service of describing according to above mentioned white paper is used is common SIP or IMS foundation structure.
At another white paper, by Forum Nokia, being accomplished can be at website http://www.forum.nokia.com/main/1,040,00.html? on fsrParam=2-3-/mai n.html & filelD=5336, disclose in the article of available and " White Paper:IP Convergence Based On SIP:Enhanced Person-To-Person Communications " by name that download, described and used Session Initiation Protocol for setting up reciprocity connection type between the terminal supporting IP agreement.As described in this white paper, in order to communicate by letter, IP-based application must have the mechanism that arrives correspondent.Today, fixing and mobile telephone network has been carried out this mission critical connecting.By dialing another user's telephone number, network can be set up special connection between any two terminals.This crucial connection ability does not extensively exist yet in internet.According to this white paper, by the supplementary session management based on SIP of other crucial mobile network's ability (that is, checking, roaming, and the network interconnection providing according to IMS standard), provide required structure.Utilize the realization of this system, likely between two terminals, set up IP and connect.Once connect, set up, it just can be used to exchange all types of communication medium (voice, video, content etc.).Be similar to HTTP, SIP is text based client-server agreement.SIP is designed to foundation, modification and ending multimedia session or calling, and it at " sip terminal ", (or user agent UA) can serve as client and server and in fact be different from HTTP on the two.Therefore, may set up the communication of client-to-client.According to this this white paper, the 6th edition (IPv6) of IP agreement provides solid foundation for the service based on SIP.The benefit of IPv6 maximum is exactly huge address space.In fact, in this this white paper, also emphasized the problem of IP agreement the 4th edition (IPv4), and the today of testing than internet, this agreement has been designed to the Internet host of smaller amounts.When the cell phone of more than one hundred million (or upper 1,000,000,000) will be connected on internet, the problem of address space will become very outstanding.In the possible application of the described Session Initiation Protocol of this this white paper, quoted real-time video share service as proof.

For example, with reference to figure 2, the first user of the mobile network 20 under mobile terminal 12 makes a call to the second user of the affiliated mobile network 20 of mobile terminal 14.The first mobile terminal 12 is served by BTS 32, and the second mobile terminal 14 is by BTS 32 ' service, and BTS 32 ' can be the identical or different BTS of BTS 32 from first class services mobile terminal.When having accepted calling, the second user sets up the first connection C1, to support the voice communication between the first and second users.Connect C1 sets up in a bi-directional way conventionally in mobile network 20 circuit domain 35.At mobile network 20 the interior connection of second between mobile terminal 12 and mobile terminal 14 C2 that sets up of packet domain 51, to allow the first and second users to share some videos during their telephone conversation.Connecting C2 can set up in unidirectional or two-way mode: the connection by unidirectional type can realize higher bit rate.Can adopt known technology to realize mobile terminal 12,14 keeps these two to connect C1 and C2 is movable simultaneously: for example, and the many RAB technology for third generation mobile terminal of having quoted, and for the DTM technology of second generation mobile terminal.
Fig. 3 has schematically illustrated to use the example of the mobile terminal 12 of composite services from the angle of functional module.Mobile terminal 12 comprises the antenna 121 that is applicable to sending/receiving, radio-frequency (RF) transceiver 122, GPRS module 123, coding/decoding unit 124, loud speaker 125, video camera 126, microphone 127, screen 128, keyboard 129, the processor (or CPU, CPU) 130 with associated memory 131.Mobile terminal 12 is typically associated by suitable electrically contacting with SIM (subscriber identity module, not shown in Fig. 3).
Antenna 121 allows communicating by letter of dealing mobile network's radio base station conventionally with radio-frequency (RF) transceiver 122.Loud speaker 125 and microphone 127 convert electrical signals to corresponding voice in the signal that the user of mobile terminal 12 can hear conventionally, and vice versa.Keyboard 129 allows user and mobile terminal manually mutual conventionally, to send dependent instruction, for example, choice menus option or selection telephone number etc.Screen 128 can be LCD screen (LCD, liquid crystal display) for example, and it is applicable to display video conventionally.Video camera 126, for example CCD (electric charge lotus root locking device) video camera, is applicable to catch video conventionally.GPRS module 123 generally includes group and wraps/unpack device and buffering area, and it can encapsulate the radio blocks from mobile network in grouping, or the radio blocks in the grouping being provided by a upper protocol layer is provided, for sending to mobile network by radio-frequency (RF) transceiver 122 and antenna 121.Coding/decoding unit 124 (for example H.263 Video Codec) is connected to loud speaker 125, microphone 127, display screen 128 and video camera 126: it is management or the video that will on display screen 128 show that capture by video camera 126 and/or that capture or will send to the coding/decoding of the audio frequency component of loud speaker 125 by microphone 127 conventionally.Operation and the comings and goings of the disparate modules comprising in processor 130 monitoring mobile terminals 12.The memory 131 combining with processor 130 comprises the software application for supervisory communications.Especially, according to an aspect of the present invention, memory 131 comprises the application software at least one composite services of control and management.Observe in addition, although coding/decoding Unit 124 are as shown in independent entity in Fig. 3, it also can be realized by means of the software program residing in the memory 131 of mobile terminal 12.
As mentioned above, according to an aspect of the present invention, on user's the mobile terminal that can use composite services, the software application for control and management composite services has been installed.This software application can realize as independent Client application, and it can be arranged in the operating system of mobile terminal, or " connection (cabled) " is in the firmware of mobile terminal.Especially, software application comprises being configured for and controls from mobile terminal to circuit domain and the module connecting to packet domain.Software application can automatically start when mobile terminal starts.Yet it can also can be forbidden automatically starting this with user and should be used to provide, or this application is manually carried out by user.Optimization software is applied in running background to produce the in fact result of " invisible " to user between the normal operating period of mobile terminal.Once carry out, this software application just can be identified the event signaling relevant with the calling coming and/or past this mobile terminal is performed.Especially, this application can be identified at least:
The signaling of relevant incoming call of setting up in circuit domain; And/or
The relevant signaling of breathing out of setting up coming into force in circuit domain; And/or
The signaling of the interruption of the local ongoing calling of carrying out in circuits territory; And/or
The signaling of the interruption of the ongoing calling of long-range execution in circuits territory.
Observe at least two kinds of situations listed above and be also included in the possibility of the end of calling in the situation outside radio coverage by chance of mobile terminal (or remote mobile terminal) during calling.In addition, observe the full list that situation listed above does not form the Possible event that software application can identify.
In the situation that mobile terminal affiliated user wants another one user (belonging to same mobile network or different, fixing or mobile network) to call out, the routine of the telephone number that will call out user select (conventionally by keyboard, carry out or the SIM from be stored in mobile terminal or on it in phone directory in select) during software application nonintervention.Calling subscriber can the interlocutor to him/her start to call out in completely normal mode, presses typically suitable button on mobile terminal.This calls out route in circuit domain conventionally.
When called subscriber answer, just in the circuit domain of communication network, between calling subscriber's mobile terminal and called subscriber's terminal, connect.When this connection is set up, to calling subscriber's mobile terminal, send a confirmation, its connection that calling subscriber can be used just set up is for communicating by letter with his/her interlocutor.Software application intercepts this confirmation signaling and automatic (that is, using terminal interaction without user) startup connection procedure in mobile network's packet domain.Conventionally, this process is provided to the connection of packet domain access point (APN, APN).This connection procedure hypothesis GGSN 54 typically notifies APN just asking the telephone number of the terminal of this connection by radius protocol.After having checked its voucher, APN makes the unique address (IP address typically) in packet domain be associated with this telephone number, and identical information is sent to GGSN 54, otherwise GGSN 54 is forwarded to identical information to have asked the terminal connecting.APN also keeps the association between the telephone number identifier of mobile terminal (or in circuit domain) of mobile terminal and institute's distributing IP address address of mobile terminal (or in packet domain) in suitable database.This association can also be sent to the miscellaneous equipment in network, such as WAP gateway.To the connection of packet domain typically with opening from mobile terminal to SGSN and the PDP Context of the GGSN of mobile network's GPRS network core completes.
Equally, once set up grouping, connect, calling subscriber just has available circuit and connects with by voice and his/her interlocutor's general communication, and has the grouping connection that access data is served simultaneously.In other words, calling subscriber can use at least one composite services.For example, calling subscriber can utilize grouping to connect and check one or more webpages from its mobile terminal, and he/her can utilize circuit to connect the content that this webpage is discussed with his/her interlocutor simultaneously.In another example, user can utilize grouping to connect the content of his/her E-mail address is downloaded on his/her mobile terminal, and he/her can utilize circuit to connect the content that the one or more email messages that receive are discussed with his/her interlocutor simultaneously.If called subscriber's terminal is equally also connected to packet network (or typically having an IP address), the equity that can set up in packet domain between these two user terminals connects, to allow the to/from called subscriber's of calling subscriber's sending/receiving video call, and he/her can comment on the image occurring in two terminals with together with his/her interlocutor simultaneously.In order to set up equity, connect, two users' terminal exchanges themselves address (typically being their IP address) in packet domain.In order to carry out this exchange, the software application of moving in the terminal of at least one in two users for example command routing comprises the message of the terminal that is addressed to this long-distance user of its IP address.This message can be for example SMS (sending and receiving short messages service) or USSD (unstructured. supplementary service data) type of message.Preferred equity connection creates a mechanism and will in description of the invention, occur subsequently.
In order to make gladly to enjoy service, after grouping connection is set up, it is available that software application typically makes one or more menu options become on mobile terminal, for connecting by grouping, uses available specific data services.Typically, this menu option can be accomplished to be activated by software application by button suitable on keyboard (or soft key).For example, in simple web page, browse or mail downloads in the situation that, relevant menu option can become available when the IP address receiving from APN.In the situation that sharing video with long-distance user, after the confirmation that can use these composite services the reciprocity establishment of connection and/or the long-distance user that for example receive from long-distance user, activate easily related menu option.Becoming among the available menu option of sharing composite services for video, may have for example to start the option that video sends and/or the option sending for break of video and/or video and suspend (or freeze frame) option.Especially, the in the situation that of freeze frame and/or image transmission interruption, it can cause making easily the last piece image (or frame) of being taken by video camera and just encoded by coding unit before video capture interrupts to keep available in two users' terminal.In fact, compare with the run-of-the-mill of transmitted video, this last piece image can accomplish in the terminal of receiver, video, to have higher quality: this depends on owing to carrying out in essence interpolation on each frame and for obtaining each follow-up frame (due to the identical width always of image in fact), makes the more efficiently fact of coding of still image.
What above reference was described from the execution of user's calling uses the process of composite services to carry out the incoming call situation that a small amount of change can also be applied to receive user his/her terminal for realizing.In the case, the active procedure of the connection in packet domain can be according to coming the signaling of the call setup of automatic network to trigger, and it typically sends by the suitable button of pressing on the keyboard of terminal after user receives external call.
When calling subscriber or called subscriber determine to finish the audio call in circuit domain, one of them of two users typically buttons to end calling by pressing suitable in his/her terminal.Connection in circuit domain is cancelled thus.Preferably, once receive the confirmation that the connection in circuit domain is cancelled, make it possible to use resident software application autocommand on user's the mobile terminal of composite services to cancel the connection in packet domain.In addition, the menu option of relevant these composite services becomes unavailable from this software application.Same process can be applied to cover owing to lacking radio the situation (in the situation that using mobile terminal) that finishes the calling in circuit domain.Therefore mobile terminal turns back to its normal holding state, prepares to receive or carry out calling (and the management with running background allows to use the software application of composite services).
The above circuit and two kinds of establishment of connection processes of grouping, and allow to use the process of composite services to there are several advantages.First, this realization is so that the complete transparent mode of user is occurred, and in fact user implements or receipt of call in circuit domain in completely normal mode, finds that his/her terminal is also arranged to use grouping connection when access success is set up.In addition, grouping connects the fact of in fact only opening in the process of audio call and allows available composite services to the user of larger quantity, can use potentially, without utilizing the packet network wherein realized IPv6 agreement, and from the angle of Virtual network operator without having in sizable IP available address pool to be solved according to use IPv4 agreement in the situation that.In fact, the address in packet domain is only distributed after having set up audio call, and is preferably when the end of same call and discharges.
In order further to avoid " waste " of IP address, the software application of management composite services can not configure not to be triggered to the mode of the connection procedure of packet network under some particular cases of circuit calling.For example, in the situation that application software only allows to use wherein two users can exchange the composite services of some videos, connection procedure to packet network can come into force or in the situation that particular number receives, become unavailable in calling: for example, during calling out free code, or during the number of calling out corresponding to information service and/or telephone-answering system service, come or number abroad during (with reside at external telex network during in the disabled situation of this service), or coming or toward belonging to other operators or using the calling of the network of different technologies (or for from being fixed to mobile " mixings " calling, vice versa) during, etc..Can be by being typically configured to get rid of by aerial operation update software application opening that grouping connects under these particular cases.In addition, particularly in composite services, to mobile terminal, send video and become available in the situation that, in the situation that the quality of radio signal or intensity are lower than under a specific critical thresholding, can cause easily the connection procedure that is not triggered to packet network.Serving only at third generation networks (3G, UMTS for example) upper available, and do not have for example, to have carried out identical consideration in the situation of enough 3G coverages (yet by second generation network, GSM/GPRS, has guaranteed that coverage is to carry out normal audio call) yet.
In the following description, according to an aspect of the present invention, the preferred embodiment of the composite services between two of detail display mobile communications network user User_A, User_B by way of example.Mobile terminal UE _ A and UE_B are provided to respectively user User_A and User_B.Composite services are that for example " gained is finding " (SWIS) or the service of " video share " type,, wherein User_A and User_B can be by the reciprocity connection types in packet domain, and during the normal telephone session of setting up in circuit domain, exchange is by the service of the video that integrated video camera is taken in their mobile terminal UE _ A separately and UE_B.The equipment comprising in the packet domain of this service by mobile communications network makes may and be managed, this equipment represents with " SWIS " (hereinafter referred to " SWIS server ") in Fig. 4, the APN that it is connected to the packet domain that is linked into mobile communications network, utilizes SWIS server mobile terminal UE _ A can communicate by letter with UE_B.Fig. 4 shows a kind of very common scheme of institute's framework.
Fig. 5 shows in this example, makes user User_A and User_B can use this to serve the flow process of performed different operating.When terminal UE _ A and UE_B start (501,502), user User_A and User_B register in mobile communications network.Except this registration, terminal UE _ A and UE_B preferably activate management with automated manner and allow the software application (hereinafter referred to " SWIS application ") of using " gained is finding " composite services and using itself.It is upper that SWIS application is preferably loaded into terminal UE _ A and UE_B in back way, and the management of SWIS service is to occur user User_A and the transparent mode of User_B by this way.
At a time, user User_A calling party User_B (503).Calling can be initiated according to any typical form by user User_A, for example, by the keyboard of terminal UE _ A, insert the telephone number of user User_B, or on terminal UE _ A or in the phone directory of storing on associated SIM, search for this number.User User_A typically presses suitable button and starts calling party User_B on his/her keyboard of terminal UE _ A.This calling is routed to terminal UE _ B at the MSC MSC_B of its lower registration by terminal UE _ A at the MSC MSC_A of its lower registration, and is routed to therefrom terminal UE _ B.Incoming call notice (504) is sent to terminal UE _ B: typically, be a demonstration screen display at terminal UE _ B of called subscriber User_B corresponding to this notice, there is the message of indication of telephone number of the terminal of calling subscriber User_A.User User_B typically presses suitable button and accepts this calling (505) on his/her terminal UE _ B.User User_B is informed to terminal UE _ A (506) of user User_A to the acceptance of this calling, and just between terminal UE _ A and terminal UE _ B, has set up calling thus.These two user User_A and User_B can converse by connection and the other side who sets up in the circuit domain of mobile communications network by this way.Call establishment is illustrated by the grey thick line between MSC MSC_A and MSC_B in Fig. 5.
When receiving the notice (506) that user User_B accepted to call out, parallel with being connected of activating in circuit domain, the SWIS application of the upper operation of terminal UE _ A of user User_A and being connected of packet domain (507) that automatic (that is, mutual without the user User_A with on terminal UE _ A) is concurrently activated to mobile communications network that be connected of activating in circuit domain.The connection of typically, arriving to the connection request of packet domain the access point APN (for example, radius server) that wherein voucher of user User_A (that is, he/her uses the right of packet service) obtains checking.If user User_A has the right to use packet service, be the unique address IP_addA in packet network of his/her terminal UE _ A dynamic assignment, typically be IP address.In this access point, the telephone number CLI_A of the terminal of maintenance customer User_A (or another identifier of terminal UE _ A of circuit intra domain user User_A) and distribute to the association between IP address ip _ addA (or another identifier of terminal UE _ A of grouping intra domain user User_A) of terminal UE _ A typically.In the miscellaneous equipment that this association can also comprise in the packet domain of mobile communications network, be maintained.By grouping, connect, terminal UE _ A of user User_A can access the packet network core PS of mobile communications network and make to serve available by it.In GPRS or UMTS network, this is corresponding to the PDP Context of opening from terminal UE _ A to packet network PS core.
In a similar fashion, when the calling receiving from user User_B, the SWIS application of the upper operation of terminal UE _ B of user User_B and being connected of packet domain (508) that automatic (that is, mutual without the user User_B with on terminal UE _ B) is concurrently activated to mobile communications network that be connected of activating in circuit domain.The connection of typically, arriving to the connection request of packet domain the access point APN (for example, radius server) that wherein voucher of user User_B (that is, he/her uses the right of packet service) obtains checking.The access point APN that terminal UE _ B is connected to can be the identical or different access point of access point being connected to terminal UE _ A.If user User_B has the right to use packet service, be the unique address IP_addB in packet network of his/her terminal UE _ B dynamic assignment, typically be IP address.In this access point, the telephone number CLI_B of the terminal of maintenance customer User_B (or another identifier of terminal UE _ B of circuit intra domain user User_B) and distribute to the association between IP address ip _ addB (or another identifier of terminal UE _ B of grouping intra domain user User_B) of terminal UE _ B typically.In the miscellaneous equipment that this association can also comprise in the packet domain of mobile communications network, be maintained.By grouping, connect, terminal UE _ B of user User_B can access the packet network PS core of mobile communications network and make to serve available by it.In GPRS or UMTS network, this is corresponding to the PDP Context of opening from terminal UE _ B to packet network PS core.
After receiving address ip _ addA, the SWIS application activating of the upper operation of terminal UE _ A of user User_A is to the transmission (509) of the registration request of SWIS server.The activation of this request occurs with automated manner, thereby reaches the transparent result to user User_A.Utilize this request (509), terminal UE _ A sends the signal of its appearance in mobile network's packet domain to SWIS server.Advantageously, in registered application (509), terminal UE _ A can also, by the packet domain of mobile communications network, with being connected concurrently of having set up in circuit domain, require to allow the connection of terminal UE _ B.Reach this result, terminal UE _ A must know the address of terminal UE _ B in packet domain, i.e. address ip _ addB.In one is preferably realized, the request being sent by terminal UE _ A at least comprises address (typically being IP address ip _ addA) and the identifier (typically be the telephone number CLI_B of user User_B) of terminal UE _ B in circuit domain in the packet domain of distributing to terminal UE _ A, utilizes this identifier by the call connection user User_A having set up in circuit domain.In a preferred embodiment, the request being sent by terminal UE _ A can comprise that one or more TCP or UDP divide into groups, and this packet bearer wherein identifier CLI_B obtains the address ip _ addA transmitting.SWIS server receives the request from terminal UE _ A, and in storage area, preserves address ip _ addA of terminal UE _ A and the identifier CLI_B of user User_B.The suitable equipment comprising in packet domain by inquiry (510) mobile communications network, the access point APN (or WAP gateway) that for example terminal UE _ A is connected to, the identifier CLI_A of terminal UE _ A that SWIS server obtains the address ip _ addA in the packet domain of mobile communications network corresponding to terminal UE _ A in the circuit domain of mobile communications network.Address ip _ the addA of this identifier CLI_A and request receiving by being sent by terminal UE _ A explicitly also by SWIS server stores in storage area.
In a similar fashion, after receiving address ip _ addB, the SWIS application activating of the upper operation of terminal UE _ B of user User_B is to the permission of SWIS server and manage the transmission (512) of the request of this service.The activation of this request occurs with automated manner, thereby reaches the transparent result to user User_B.Utilize this request (512), terminal UE _ B sends its signal occurring in mobile network's packet domain to SWIS server.Advantageously, in registration request (512), terminal UE _ B can also, by the packet domain of mobile communications network, with being connected concurrently of having set up in circuit domain, require to allow the connection of terminal UE _ A.For this purpose, terminal UE _ B must know the address of terminal UE _ A in packet domain, i.e. address ip _ addA.In one is preferably realized, the request being sent by terminal UE _ B at least comprises address (typically being IP address ip _ addB) and the identifier (typically be the telephone number CLI_A of user User_A) of terminal UE _ A in circuit domain in the packet domain of distributing to terminal UE _ B, utilizes this identifier by the call connection user User_B having set up in circuit domain.In a preferred embodiment, the request being sent by terminal UE _ B can comprise that one or more TCP or UDP divide into groups, and this packet bearer wherein identifier CLI_A obtains the address ip _ addB transmitting.SWIS server receives the request from terminal UE _ B, and in storage area, preserves address ip _ addB of terminal UE _ B and the identifier CLI_A of user User_A.The suitable equipment comprising in packet domain by inquiry (513) mobile communications network, the access point (or WAP gateway) that for example terminal UE _ B is connected to, the identifier CLI_B of terminal UE _ B that SWIS server obtains the address ip _ addB in the packet domain of mobile communications network corresponding to terminal UE _ B in the circuit domain of mobile communications network.Address ip _ the addB of this identifier CLI_B and request receiving by being sent by terminal UE _ B explicitly also by SWIS server stores in storage area.
In this, SWIS server has following available information: corresponding to identifier CLI_A, the terminal request with address ip _ addA is connected to the terminal with identifier CLI_B; Corresponding to identifier CLI_B, the terminal request with address ip _ addB is connected to the terminal with identifier CLI_A.The coupling of these information that can store with suitable charting according to SWIS server, SWIS server can identify terminal UE _ A and UE_B has been connected to circuit domain, and allows thus the parallel equity between two terminals in packet domain to connect.This realize available by packet domain between terminal UE _ A and UE_B IA interchange address IP_addA and IP_addB occur.
Address ip _ addA and IP_addB can be inserted this address and drive in the confirmation signaling separately by registration request (509,512) separately before will sending to they of terminal UE _ A, UE_B one or both of by SWIS server in the exchange between terminal UE _ A and UE_B.In a preferred embodiment, the address of " interlocutor " terminal in packet domain is inserted in the confirmation signaling that only sends to a terminal.This confirmation can for example be sent to terminal UE _ B (514), comprises address ip _ addA of terminal UE _ A, sends one " sky " simultaneously and confirms that (511) are to terminal UE _ A.Once receive this confirmation (514), the SWIS application fetches of the upper operation of terminal UE _ B goes out address ip _ addA and is stored in the storage area of terminal UE _ B.In addition, when extracting address ip _ addA of terminal UE _ A, the relative address IP_addA that the SWIS applications exploiting of the upper operation of terminal UE _ B has just received, comprise its oneself address ip _ addB, in packet domain, use automatic message distribution (515) to reply terminal UE _ A: this message can be peer message cover joint word type, by having comprised that TCP or the UDP grouping of predetermined characteristic sequence realizes.Address ip _ addB of terminal UE _ B is extracted in the SWIS application of the upper operation of terminal UE _ A from these message, and is stored in the storage area of terminal UE _ A.In addition, once receive address ip _ addB of terminal UE _ B, the SWIS application of the upper operation of terminal UE _ A just typically on the display screen of terminal UE _ A automatic activation by the available menu option of suitable button (or soft key) of the keyboard of same terminal, by this menu option user User_A, can activate the video camera integrated with his/her terminal UE _ A and send the video that comprises by the image of the real-time shooting of this video camera to terminal UE _ B.What in addition, the SWIS of the upper operation of terminal UE _ A applied message (515) that automatic transmission sends by terminal UE _ B before having received confirms terminal UE _ B (516).Once receive this confirmation (516), the SWIS application of the upper operation of terminal UE _ B just typically on the display screen of terminal UE _ B automatic activation by the available menu option of suitable button (or soft key) of the keyboard of same terminal, by this menu option user User_B, can activate the video camera integrated with his/her terminal UE _ B and send the video that comprises by the image of the real-time shooting of this video camera to terminal UE _ A.
In this, terminal UE _ A of two user User_A and User_B and UE_B make it possible to use completely SWIS service.Advantageously, two terminal UE _ A and UE_B allow to use combination S WIS service, the regular event of the regular event of the call of carrying out except user User_A and this calling of reception of being carried out by user User_B, do not relate to user User_A and the User_B any further action on terminal UE _ A and UE_B.This advantage especially realizes because of the following fact: by terminal UE _ A and UE_B, to SWIS server, sent, for ask the request (509 of the interlocutor that the connected address in packet domain in circuit domain, 512) can't help SWIS server (is forwarded to terminal oneself, the request that terminal UE _ A sends can not be forwarded to terminal UE _ B, vice versa), but they stop at server S WIS place.This makes to have been avoided by user User_A and User_B in order to allow this service and clearly to be received and be connected to become necessity on packet network equally by the action on terminal UE _ A and UE_B for this video of sending/receiving.Equally at terminal UE _ A and UE_B, activating menu option occurs in automatic mode owing to receiving from the simple acknowledge message of SWIS server.The request of terminal UE _ A and UE_B transmission is not forwarded to SWIS server, and uses acknowledge message to allow to realize the quantity that SWIS serves required signaling message between remarkable reduction terminal UE _ A, UE_B and SWIS server as the trigger of the upper menu option activation of UE_B of terminal UE _ A.This advantageously allows to make SWIS service to user User_A and User_B, can use within the quite short time.
Refer again to Fig. 5, in the situation that user User_A wants to start to user User_B transmission video, he/her presses the button (or soft key) of the menu option activating on the display screen corresponding to the terminal UE _ A at him/her.Alternatively, the SWIS application of the upper operation of terminal UE _ A sends the notice of " startup video " (517) from trend SWIS server, for example, for the object of service charging, allow SWIS startup of server for transmitting the counting of the video institute service time being sent by user User_A.In addition, the upper available menu option of terminal UE _ A is revised in the SWIS application of the upper operation of terminal UE _ A, make by this way its with from the transmission of video of user User_A stop keep strokes (optional, it forbids aforesaid menu option, and activates and can by the another one option of different buttons or soft key activation, " stop video ").In addition, the SWIS application activating of the upper operation of terminal UE _ A is caught the image from the video camera of terminal UE _ A, and activates the correlative coding that is applicable to transmission on grouping connects.Finally, the connection realizing in the packet domain of the SWIS of the upper operation of terminal UE _ A application by mobile communications network, utilizes its address ip _ addB to terminal UE _ B, to send the image (518) (may use buffer) of coding.User User_A can see that he/her is just sending to the video of user User_B on his/her display screen of terminal UE _ A.Advantageously, in this stage, the communication between SWIS server nonintervention UE_A and UE_B.This allows still to use the equipment control of quite limited disposal ability for the SWIS service of a large number of users, the data flow of non-complex because this equipment only must manage simple signaling message.Once receive video (may utilize buffer to carry out by terminal UE _ B), user User_B just can see this video on his/her display screen of terminal UE _ B.The menu option that the video on terminal UE _ B sends is preferably forbidden in the SWIS application of the upper operation of terminal UE _ B, to avoid connecting the conflict of setting up in the packet domain of mobile communications network.When user User_A determines to stop video transmission, he/her just presses and has just made the button that stops video (or soft key) available on the display screen of terminal UE _ A: the SWIS application of the upper operation of terminal UE _ A stops catching from the image of video camera and to terminal UE _ B, transmits the image of encoding.Alternatively, the SWIS application of the upper operation of terminal UE _ A sends the notice of " stopping video " (519) from trend SWIS server, for example, for the object of service charging, the counting of the video institute service time that allows that SWIS server stops that transmission sends by user User_A.
Similarly, in the situation that user User_B wants to start to user User_A transmission video, he/her just presses the button (or soft key) of the menu option activating on the display screen corresponding to the terminal UE _ B at him/her.Alternatively, the SWIS application of the upper operation of terminal UE _ B sends the notice of " startup video " (520) from trend SWIS server, for example, for the object of service charging, allow the counting of SWIS startup of server for video institute service time of transmitting user User_B and sending.In addition, the upper available menu option of terminal UE _ B is revised in the SWIS application of the upper operation of terminal UE _ B, make by this way its with from the transmission of video of user User_B stop keep strokes (optional, it forbids aforesaid menu option, and activates and can by the another one option of different buttons or soft key activation, " stop video ").In addition, the SWIS application activating of the upper operation of terminal UE _ B is caught the image from the video camera of terminal UE _ B, and activates the correlative coding that is applicable to transmission on grouping connects.Finally, the connection realizing in the packet domain of the SWIS of the upper operation of terminal UE _ B application by mobile communications network, utilizes its address ip _ addA to terminal UE _ A, to send the image (521) (may use buffer) of coding.User User_B can see that he/her is just sending to the video of user User_A on his/her display screen of terminal UE _ B.Advantageously, in this stage, the communication between SWIS server nonintervention UE_B and UE_A.Once receive video (may utilize buffer to carry out by terminal UE _ A), user User_A just can see this video on his/her display screen of terminal UE _ A.The menu option that the video on terminal UE _ A sends is preferably forbidden in the SWIS application of the upper operation of terminal UE _ A, to avoid the conflict that in the packet domain of mobile communications network, above connection is set up.When user User_B determines to stop video transmission, he/her just presses and has just made the button that stops video (or soft key) available on the display screen of terminal UE _ B: the SWIS application of the upper operation of terminal UE _ B stops catching from the image of video camera and to terminal UE _ A, transmits the image of encoding.Alternatively, the SWIS application of the upper operation of terminal UE _ B sends the notice of " stopping video " (522) from trend SWIS server, for example, for the object of service charging, the counting of the video institute service time that allows that SWIS server stops that transmission sends by user User_B.
In one of them of two users, user User_A for example, want to finish in the situation of communicating by letter with user User_B, he/her typically presses suitable button on his/her keyboard of terminal UE _ A, thereby wants the Notice of Intention (523) of terminated call to mobile communications network (in circuit domain) him/her.SWIS application intercepting (524) such a notice of the upper operation of terminal UE _ A also sends and finishes the signaling (526) that service is used to SWIS server.Terminal UE _ B of another user User_B receives the notice (525) of terminated call in circuit domain.The SWIS application of the upper operation of terminal UE _ B is truncated to such a notice and sends and finish the signaling (527) that service is used to SWIS server.SWIS server can be used confirmation (528,529) to reply the signaling from terminal UE _ A and UE_B.Once receive this confirmation, the SWIS application of the upper operation of terminal UE _ A and UE_B just can be ordered terminal UE _ A of making in packet domain and the connection invalid (530,531) of UE_B, and discharges address ip _ addA and IP_addB.The end of calling out between the terminal UE _ A in circuit domain and UE_B is indicated by another grey thick line in Fig. 5.
Above description can both be supported the situation of composite services with reference to wherein terminal UE _ A and UE_B.In the situation that for example, by supporting the terminal (UE_A) of composite services to call out the terminal that can not support composite services, the SWIS application automatic activation of the upper operation of terminal UE _ A is to the connection of packet domain, it receives the address ip _ addA of oneself, and sends a request for registration to SWIS server.As illustrational before, in the executed situation of calling of the well afoot to particular number, forbid that such a process is favourable.Under any circumstance, if terminal UE _ A does not receive IP address in to the confirmation of its registration request or in reciprocity socket in predefined overtime (typically configurable) scope, SWIS application can disconnect from packet domain by autocommand, thereby discharges fast useless " waste " IP address.For example, in the situation that can support the terminal (UE_B) of composite services to receive from the calling that can not support the terminal of composite services, the SWIS application automatic activation of the upper operation of terminal UE _ B is to the connection of packet domain, it receives the address ip _ addB of oneself, and sends registration request to SWIS server.As illustrational before, in the situation that the call source of well afoot from particular number, forbids that such a process is favourable.Under any circumstance, if terminal UE _ B does not have at its registration request or receive IP address in reciprocity socket in predefined overtime (typically configurable) scope, SWIS application can disconnect from packet domain by autocommand, thereby discharges fast useless " waste " IP address.Similar overtime also can realization for managing the possible problem of grouping establishment of connection.These overtime duration can be passed through the suitable field domain in the response message of registration request by server, or by typically configuring by aerial operation.
In a preferred version, can imagine that terminal UE _ A and UE_B exchange notice and acknowledge message are to avoid the while from the situation of two terminal transmission videos.For example, as shown in Fig. 6 a, after selecting the menu option of relevant transmission of video on terminal UE _ A at user User_A at him/her, the SWIS of the upper operation of terminal UE _ A application sends a notification message (in Fig. 6 a, being expressed as INVITE) automatically to terminal UE _ B.Once receive this notification message, the SWIS application of the upper operation of terminal UE _ B is just set up the reception of video and is automatically sent acknowledge message (being expressed as ACK in Fig. 6 a) to terminal UE _ A.Once receive this confirmation, the SWIS application of the upper operation of terminal UE _ A just starts transmission of video.
At " simultaneously ", from terminal UE _ A and UE_B notice distribution message in the situation that, as shown in Figure 6 b, can adopt the realization of priority policy agreement.For example, in these cases, this strategy can offer priority the terminal making a call in circuit domain.Other strategy also can be selected.In above-described example, UE_A is the terminal making a call in circuit domain.As shown in Figure 6 b, in the situation that UE_B sends its oneself notification message to UE_A simultaneously, UE_B receives the confirmation that replaces his notification message from the notification message of UE_A.In the case, priority policy is followed in the SWIS of the upper operation of terminal UE _ B application, sends the confirmation to the notification message from UE_A.
In going back a preferred version, can add the use of Session ID to aforesaid function, Session ID, is connected to identify two equities between terminal to terminal UE _ A and UE_B by SWIS server-assignment.This Session ID allows to make communication protocol, and key is strong more, and as will be pointed in the following description, it also allows to simplify the structure of at least some message, so that the implementation procedure of composite services can be accomplished more effectively and be quick.Specifically, illustrational process can revise to distinguish from terminal UE _ A at SWIS server as follows before, two kinds of dissimilar registration requests of UE_B: the first registration (for example, carry out while being applied in the first calling by SWIS or received by associated terminal after connection), a first registration registration subsequently.Two dissimilar registration requests are distinguished based on the following fact: in the first registration request, SWIS application does not send to SWIS server by Session ID (being after this called SessionID), the SessionID simultaneously being received by SWIS server before SWIS application insertion in the registration request after the first registration request.
More particularly, reference terminal UE_A, first when registration at SWIS server place, after having opened the connection in packet domain, terminal UE _ A sends registration request to SWIS server, and as previously mentioned, request comprises its address ip _ addA and the telephone number CLI_B of terminal UE _ B.As pointing out more in detail in the following description, in the first registration request, can comprise more parameter, the parameter of the configuration of the Video coding of the relevant upper setting of terminal UE _ A for example, and/or the parameter of relevant SWIS application version, and/or terminal UE _ A be connected to for opening the address of the APN that grouping connects.In the first registration request, do not comprise parameter S essionID, because SWIS server does not also send it to terminal UE _ A.
SWIS server receives the registration request from terminal UE _ A, extracts its address ip _ addA, and the existence of identification parameter SessionID.Based on this parameter, SWIS server request APN is to obtain the telephone number CLI_A of terminal UE _ A.Once telephone number CLI_A obtains, SWIS server just generates Session ID SessionID.This identifier can consist of for example numeral or alphanumeric random sequence.In a preferred embodiment, SWIS server generates key ID, uses this key ID scrambler phone number CLI_A.According to this key ID and according to the telephone number CLI_A that uses this secret key encryption, SWIS server generates Session ID SessionID, for example:
SessionlD＝(CLI_A)
ID+[ID]
x
Symbol (CLI_A) herein
iDthe telephone number CLI_A that expression is encrypted by means of key ID, and symbol [ID]
xrepresent that key ID is not expressly but is preferably SWIS server uses the same algorithm using when calculating CLI_A, and only use and to draw for the key X computations known to SWIS server.Thereby the parameter S essionID producing sends to terminal UE _ A by SWIS server in the acknowledge message of the registration request to before it.In this acknowledge message, SWIS server can comprise other information in addition, for example may revise the parameters of the Video coding of terminal UE _ A.Once SWIS server verification terminal UE_A and UE_B has had the calling of well afoot in circuit domain, same Session ID SessionID also sends to terminal UE _ B in its confirmation of registration request.Once set up the equity in packet domain, connect, this parameter S essionID can advantageously be comprised in the message of terminal UE _ A and UE_B exchange, so that communication protocol is due to relevant intersection control, key is strong more.
In registration request after the first registration request, the interlocutor (for example same terminal UE _ B or three terminal UE _ C) of terminal UE _ A on sending in its oneself address ip _ addA, circuit domain telephone number and the parameter S essionID that SWIS server receives in aforesaid current registration request.Preferably, in this request, terminal UE _ A no longer sends any information except previously described parameter to SWIS server.SWIS server can extract the telephone number CLI_A (key ID by means of relevant aforesaid registration request is encrypted) of the terminal UE _ A that sends this registration request from be included in the parameter S essionID registration request, and needn't again inquire APN " parsing " address ip _ addA.This allow to accelerate the implementation procedure of composite services, and has reduced the processing load on the access point APN of packet domain.Expired during the reciprocity connection closed of the Session ID SessionID that as mentioned above, sends to SWIS server by same terminal between two terminals.
