Description:
TECHNICAL FIELD 
       [0001]    The disclosure relates to a technology of converging a telecommunication network with the Internet, and in particular to a method and system for a telecommunication network to provide a session service to the Internet. 
       BACKGROUND 
       [0002]    An Internet Protocol (IP) Multimedia Subsystem (IMS) is a development direction of future multimedia communication, and is also the most important part of a Next Generation Network (NGN). The IMS is a subsystem supporting an IP multimedia service and proposed by the Third Generation Partnership Project (3GPP), and a remarkable feature of the IMS is that a Session Initiation Protocol (SIP) system is adopted and communication is independent of an access way. The IMS may have multiple capacities, such as the capacity of separating multiple multimedia service control functions from a bearing capacity, the capacity of separating a call from a session, the capacity of separating an application from a service, the capacity of separating a service from a network, and the capacity of converging a mobile network with the Internet, and etc. 
         [0003]    The IMS provides a new multimedia service form, provides more services for users, and opens up a new income source for operators. Multimedia services of the IMS include Voice over Internet Protocol (VoIP), Presence, Push-to-Talk over Cellular (PoC), InstantMessage, VideoSharing, content sharing, RichCall and the like. In addition, under an enterprise&#39;s fixed environment, the IMS can also provide a service similar to existing fixed switching service, for example, the IMS can provide an enterprise switchboard service by an IPCentrex server to implement short number interconnection within the enterprise. By an IPConference server, the IMS can provide a conference call service to enable a cell phone, a Personal Computer (PC) and a traditional telephone to be connected to the same system, so as to implement a conference call. 
         [0004]    In the current industry background, firstly mobile operators, fixed operators, and mobile/fixed mixture operators are possible to converge with one another in roles. That is, a mobile operator may become a mobile/fixed mixture operator, and a fixed operator may obtain a mobile operating license, and so on. Therefore, all telecommunication operators urgently need a technology to converge a mobile network with a fixed network together. And the IMS exactly has such a characteristic. The IMS is independent of a specific bearing type, and may provide an arbitrary IP channel with a consecutive service of IMS traffic, from voice to multimedia data etc.. The IMS also has an interworking capability with a traditional network, which enables an IMS terminal to interwork with a traditional mobile terminal and a traditional fixed terminal. 
         [0005]    A converged network will bring users new service experience. No matter what access networks and terminal devices are, users can obtain the same voice and multimedia services in the same way. As such, the compatibility of mobility and individuation is achieved. 
         [0006]    Nowadays, many famous Internet service providers have achieved great success by providing user-to-user communication services, such as MSN, QQ and Skype etc. The provided services mainly include VoIP, instant messaging, and video chat etc. Obviously, these applications have a great impact on existing telecommunication operators&#39; voice and information services. However, at the same time, if these Internet applications are transplanted to a mobile terminal, it is also a new business opportunity for telecommunication operators. And the IMS can provide such technical means. The IMS can provide services, such as VoIP, instant messaging and video chat etc., which may either replace or interwork with the above Internet services. Therefore, in the face of Internet service providers, telecommunication operators may have multiple solutions because of the existence of IMS, such as creating their own brands, competing with the Internet, and implementing the interworking cooperation or choosing competition together with cooperation. 
         [0007]    Currently, the Internet is a general trend of information communication, and Internet applications of the Internet have the integration characteristic. For example, social applications like Facebook and Google+, integrate a variety of functions, such as IM, Web2.0, Blog, audio and video chat, and audio and video conference etc., and a telecommunication network (e.g. the IMS) can also provide similar services. The telecommunication network should open session services to the Internet applications so as to provide users with a broader range of services.

         [0074]    the telecommunication network is configured to provide a session service to an Internet user, and establish a session between the Internet user and a telecommunication user or another Internet user. 
         [0075]    The telecommunication network realizes the connection with the Internet through an access gateway supporting an Internet protocol; 
         [0076]    or the telecommunication network realizes the connection with the Internet through enabling an access-side device to support an Internet protocol. 
         [0077]    The Internet protocol includes HTTP, or HTTPS, or REST, or SIP Over HTTP or WebSocket, wherein the access gateway or the upgraded access-side device realizes conversion between HTTP and SIP. 
         [0078]    The Internet user establishes the session with the telecommunication user or another Internet user through a Real-Time Communication in WEB-browsers (RTCWeb) technology, an SIP Plugin, or HTTP/SOAP/Web2.0/HTML5. 
         [0079]    The telecommunication network is further configured to allocate a number or an identifier to the Internet user, wherein the allocated number or identifier is different from a user name in the Internet; or configured to take a user name in an Internet application as the number or the identifier of the telecommunication network; 
         [0080]    the Internet user registers with the telecommunication network and initiates a session request using the allocated number or identifier or the user name in the Internet application, and/or the Internet user accepts a session request, so as to establish the session with the telecommunication user or another Internet user. 
         [0081]    The telecommunication network associates a number or an identifier of the telecommunication network with a user name in an Internet function; 
         [0082]    the telecommunication network calls an Internet user terminal or a telecommunication terminal preferentially through service control, or makes a forking call directed to the Internet user terminal and the telecommunication terminal. 
         [0083]    The access-side device is an SBC and a P-CSCF. 
         [0084]    The Internet application protocol is the HTTP/SOAP/Web2.0/HTML5 protocol. 
         [0085]    The operation that the Internet user registers with the telecommunication network using the allocated number or identifier includes: 
         [0086]    the Internet user initiates a registration request by using the HTTP/SOAP/Web2.0/HTML5 protocol; 
         [0087]    the SBC forwards the registration request to the P-CSCF by using the HTTP/SOAP/Web2.0/HTML5 protocol; 
         [0088]    the P-CSCF encapsulates the registration request as an SIP message, and forwards the SIP message to a Serving Call Session Control Function entity (S-CSCF); 
         [0089]    the S-CSCF completes the registration of the Internet user, and returns a registration success message. 
         [0090]    The operation that the Internet user initiates a session request using the allocated number or identifier includes:

         [0097]    the P-CSCF converts the call request in the format of INVITE into a call message under the HTTP/SOAP/Web2.0/HTML5 protocol; 
         [0098]    the SBC transparently transmits the call message under the HTTP/SOAP/Web2.0/HTML5 protocol to the Internet user; 
         [0099]    the Internet user responds to the call message so as to establish a session with a caller. 
         [0100]    Related network elements in the system for a telecommunication network to provide a session service to the Internet of the disclosure are further described in details below in combination with the accompanying drawings. 
         [0101]      FIG. 1  shows an architecture diagram of an Internet user acting as a caller according to an embodiment of the disclosure. As illustrated in  FIG. 1 , the Internet user uses a session service provided by a telecommunication network, acts as a caller and establishes a session with a called party. The called party may be a telecommunication user or another Internet user. 
         [0102]      FIG. 2  shows an architecture diagram of an Internet user acting as a called party according to an embodiment of the disclosure. As illustrated in  FIG. 2 , the Internet user uses a session service provided by a telecommunication network, acts as a called party, and may receive a call request from a caller and establish a session. The caller may be a telecommunication user or another Internet user. 
         [0103]      FIG. 3  shows an architecture diagram of a conference in which an Internet user participates according to an embodiment of the disclosure. As illustrated in  FIG. 3 , the Internet user uses a session service provided by a telecommunication network, acts as a participant of a conference, and implements an audio/video/whiteboard conference. The conference initiator (the conference chairman) may be a telecommunication user or an Internet user. The Internet user may initiate the conference or may be invited to attend the conference. 
         [0104]      FIG. 4  shows an architecture diagram of an Internet user accessing a telecommunication network according to an embodiment of the disclosure. As illustrated in  FIG. 4 , an Internet session client, as a part of an Internet application, may use the following technologies to implement registration, initiate a session request and accept a session request: 
         [0105]    the RTCWeb technology is employed to implement registration, initiate a session request and accept a session request; or 
         [0106]    a plug-in of a Web Browser is employed to provide an SIP function, so as to initiate SIP registration, initiate a session request and accept a session request; or 
         [0107]    a protocol such as an HTTP/SOAP/Web2.0 protocol is employed to implement registration, initiate a session request and accept a session request; or a plug-in of the HTTP/SOAP/Web2.0 or standardized HTML5 may be employed. 
         [0108]    The Internet session client may be implemented based on software or a Web Browser, or may be downloaded from a server to a browser. 
         [0109]    The Internet user may access the telecommunication network using protocols including SIP, HTTP, SOAP, and Web2.0 etc. 
         [0110]      FIG. 5  shows another architecture diagram of an Internet user accessing a telecommunication network according to an embodiment of the disclosure. As illustrated in  FIG. 5 , for the Internet user accessing the telecommunication network using protocols except the SIP protocol, an enhanced requirement is needed for the telecommunication network. The specific requirement is that for a related network element accessing the telecommunication network, an access-side device of the telecommunication network needs to support a related protocol. For example, when an Internet user accesses an IMS using protocols such as the HTTP, SOAP, or Web2.0 protocol etc., an access-side device of the IMS, such as a network element like an SBC and a P-CSCF etc., needs to support protocols such as SIP, HTTP, SOAP, or Web2.0 etc. The IMS access device (such as a P-CSCF) provides conversion mapping between protocols such as HTTP, SOAP, or Web2.0 etc. and an SIP protocol (a flow, registration, and call are needed in the embodiment). 
         [0111]    In the disclosure, a new number is dispatched to an Internet user in a telecommunication network (e.g. an IMS), and the number or identifier (e.g. a Public Switched Telephone Network (PSTN), a Mobile Station International Subscriber Directory Number (MSISDN), a Telephone Uniform Resource Identifier (Tel URI) and an SIP URI etc.) is different from a user name (e.g. an account of Fackbook or Taobao etc.) of the Internet user in an original Internet function. There is no special requirement for user management of the telecommunication network (e.g. the IMS), but an Internet function needs to associate a telecommunication network number (or identifier) with an Internet function account. 
         [0112]    Alternatively, a user name (e.g. an account of Fackbook or Taobao etc.) of an Internet user in an Internet application is used to register with and make a call in an IMS. That is, the IMS supports the user name (which may have a non SIP URI or Tel URI format) in the Internet application. 
         [0113]    Alternatively, an existing number or identifier (e.g. a PSTN, an MSISDN, a Tel URI and an SIP URI etc.) of a telecommunication network is allowed to be associated with a user name (e.g. an account of Fackbook or Taobao etc.) in an Internet function. The telecommunication network may transmit a call to the Internet or a telecommunication terminal preferentially by service control (e.g. a Multimedia Telephony Application Server (MMTel AS) of an IMS), and provide a supplementary service function such as call forwarding on no reply, or a forking call (the mechanism of Forking). The telecommunication network number (or identifier) is associated with the account of the Internet function by the Internet function. 
         [0114]    Specific applications of the convergence of the Internet with the telecommunication network are described in details below. 
         [0115]      FIG. 6  shows a flowchart of Internet user registration according to an embodiment of the disclosure. As illustrated in  FIG. 6 , the flow of the Internet user registration in the embodiment includes the following steps: 
         [0116]    1) an Internet user initiates a registration request using the HTTP or SOAP or Web2.0 protocol; 
         [0117]    2) an SBC forwards the registration request using the HTTP or SOAP or Web2.0 protocol; 
         [0118]    3) a P-CSCF converts a registration message under the HTTP or SOAP or Web2.0 protocol into SIP REGISTER; 
         [0119]    4) an S-CSCF returns  401 , with security challenge; 
         [0120]    5) the P-CSCF converts  401  into a registration failure response under the HTTP or SOAP or Web2.0 protocol; 
         [0121]    6) the SBC forwards the registration failure response under the HTTP or SOAP or Web2.0 protocol; 
         [0122]    7) the Internet user re-initiates a registration request, using the HTTP or SOAP or Web2.0 protocol, carrying authentication about the security challenge; 
         [0123]    8) the SBC forwards the registration request, using the HTTP or SOAP or Web2.0 protocol; 
         [0124]    9) the P-CSCF converts a registration message under the HTTP or SOAP or Web2.0 protocol into SIP REGISTER; 
         [0125]    10) the S-CSCF returns 2000K; 
         [0126]    11) the P-CSCF converts 2000K into a registration success response under the HTTP or SOAP or Web2.0 protocol; 
         [0127]    12) the SBC forwards the registration success response under the HTTP or SOAP or Web2.0 protocol; 
         [0128]    13) the Internet user initiates a subscription (HTTP or SOAP or Web2.0 protocol) process; and 
         [0129]    14) the P-CSCF is converted for SIP subscription. 
         [0130]      FIG. 7  shows a flowchart of an Internet user making a call through a telecommunication network according to an embodiment of the disclosure.
