Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Example one

This embodiment provides a method for implementing an internet access service based on a long term evolution voice call, as shown in fig. 1, the method includes the following steps:

step 101: and after a call response message responding to the voice call establishment request is acquired, a trigger instruction carrying the identification of the calling terminal and the identification of the called terminal is sent to an application server.

Specifically, after receiving a Call response message in response to a voice Call setup request initiated by a calling terminal, a Serving Call Session Control Function (S-CSCF) sends a trigger instruction carrying an identifier of the calling terminal and an identifier of a called terminal to an Application Server (AS) to trigger the AS.

After the called end receives the voice call establishment request sent by the calling end and responds to the call response message, the call response message is firstly sent to the S-CSCF to which the called end belongs, then the S-CSCF to which the called end belongs is sent to the S-CSCF to which the calling end belongs, and finally the S-CSCF to which the calling end belongs is sent to the calling end; the call answer message may be an off-hook 200ok (invite) message. The AS has the function of acquiring a corresponding network link address from a database according to the identification of the calling end and the identification of the called end and generating a short message carrying the network link address, and the service provided by the AS is the 'and color chain' service, for example, the service of pushing the short message carrying the network link address which is self-defined by the user at the end and matched with the user at the opposite end to the user at the opposite end based on the triggering of the calling end or the called end in the VoLTE call process. When the home terminal of the calling side where the S-CSCF is located is a called terminal and the third party registration between the called terminal and the AS is successful, namely the AS successfully authenticates the user authentication of the called terminal, the S-CSCF to which the called terminal belongs sends a trigger instruction carrying the identification of the calling terminal and the identification of the called terminal to the AS after acquiring the call response message; and when the home terminal of the calling side where the S-CSCF is located is a calling terminal and the third party registration between the calling terminal and the AS is successful, namely the AS successfully authenticates and authenticates the user authentication of the calling terminal, the S-CSCF to which the calling terminal belongs sends a trigger instruction carrying the identification of the calling terminal and the identification of the called terminal to the AS after acquiring the call response message. The AS triggered by the S-CSCF to which the called terminal belongs and the AS triggered by the S-CSCF to which the calling terminal belongs can be one same AS in physics or a plurality of ASs in physics, but the functions of the ASs are the same, namely, the services of ' color chain and ' color chain ' can be provided.

When both the calling terminal and the called terminal have signed the services of 'color chain' provided by AS, any one of the S-CSFCs to which the called terminal and the calling terminal belong can be selected to trigger AS, or the S-CSFCs to which the called terminal and the calling terminal belong can be simultaneously triggered AS. Here, AS an alternative embodiment, when both the calling terminal and the called terminal have signed the "sum chain" service provided by the AS, an S-CSCF to which only the called terminal or the calling terminal belongs may be set to trigger the AS. That is, before the S-CSCF sends the trigger instruction to the AS, the S-CSCF may need to perform Initial Filter Criteria (iFC) match detection, and allow sending the trigger instruction to the AS only when the trigger condition is met. The iFC is included in the service subscription data, and after a user completes an Evolved Packet Core (EPC) network attachment under a Long Term Evolution (LTE) network and registers in an IP Multimedia Subsystem (IMS) Core network, the S-CSCF may download the service subscription data corresponding to the user from a Home Subscription Server (HSS). The iFC can define conditions triggered by different services and different target AS corresponding to different services according to different priorities, and the S-CSCF performs iFC matching detection according to the information of the home terminal of the calling side where the S-CSCF is located. For example, when the "and color chain" service set in the iFC can only be triggered by the called party, the S-CSCF may send a trigger instruction to the AS only if the home terminal of the call side where the S-CSCF is located is the called terminal, that is, the trigger condition is satisfied.

Here, the identifier of the calling end may be a Subscriber contact Number, a private Identity, a public Identity, an International Mobile Subscriber Identity (IMSI), an International Mobile Equipment Identity (IMEI), and the like of the calling end; the identification of the called terminal can be a user contact number, a private identity, a public identity, an IMSI, an IMEI and the like of the called terminal; in this embodiment, the identifier is taken as a mobile phone number of a user, that is, the identifier of the calling terminal is taken as a mobile phone number of a calling user, and the identifier of the called terminal is taken as a mobile phone number of a called user.

Step 102: and receiving a short message carrying a network link address sent by the application server after responding to the trigger instruction.

Here, when the S-CSCF to which the called terminal belongs sends the trigger instruction carrying the identifier of the calling terminal and the identifier of the called terminal to the AS in step 101, the S-CSCF to which the called terminal belongs receives the short message carrying the network link address sent by the AS after responding to the trigger instruction; when the S-CSCF to which the calling terminal belongs sends the trigger instruction carrying the identifier of the calling terminal and the identifier of the called terminal to the AS in step 101, the S-CSCF to which the calling terminal belongs receives the short message carrying the network link address sent by the AS after responding to the trigger instruction.

Here, the network link address is used for opening a webpage corresponding to the network link address through an application such as a browser, a video player, a shopping APP and the like when being triggered, so as to implement a web service. In practical applications, the network link address may be www.baidu.com, www.souhu.com, etc. predefined in the database. For example, when the user a is the calling party and the user B is the called party, the internet link matching the user a and the user B is set to be www.baidu.com in the database, so when the user a is the calling party and calls the user B based on the mobile phone number, the S-CSCF to which the user a belongs triggers the AS to call the internet link www.baidu.com in the database by using the mobile phone number of the user a and the mobile phone number of the user B AS input information, and generates a short message carrying www.baidu.com.

Step 103: and sending the short message carrying the network link address to an opposite terminal of a call side where the service call session control function entity is located.

Specifically, the S-CSCF sends the short message carrying the network link address acquired in step 102 to the opposite end of the call side where the S-CSCF is located, so that the opposite end of the call side where the S-CSCF is located realizes the internet access service when triggering the network link address.

Here, the call side where the S-CSCF is located includes a calling side and a called side, that is, includes a network side to which the calling end belongs and a network side to which the called end belongs; when the home terminal of the call side where the S-CSCF is located is a called terminal, that is, when the S-CSCF to which the called terminal belongs sends a trigger instruction carrying the identifier of the calling terminal and the identifier of the called terminal to the AS in step 101, the S-CSCF to which the called terminal belongs sends the short message carrying the network link address to the calling terminal in step 103, so that the calling terminal can implement internet surfing by triggering the network link address; when the local end of the call side where the S-CSCF is located is the calling end, that is, the S-CSCF to which the calling end belongs sends the trigger instruction carrying the identifier of the calling end and the identifier of the called end to the AS in step 101, the S-CSCF to which the calling end belongs sends the short message carrying the network link address to the called end in step 103, so that the called end can implement internet access by triggering the network link address.

Taking the example that the S-CSCF to which the called terminal belongs sends the short message carrying the network link address to the calling terminal, and the calling terminal performs internet access based on the short message carrying the network link address, the sending flow of the short message and the implementation flow of performing internet access based on the network link address are specifically described as follows:

the S-CSCF to which the called end belongs sends the Short Message carrying the network link address to a communication Protocol Short Message Gateway (IP-SM-GW, Internet Protocol Short Message Gateway) of the called end, so that the IP-SM-GW of the called end sends the Short Message to a Short Message center through a signaling network; the method comprises the steps that a short message center sends routing request information of short messages to a three-fusion HSS to which a user of a called end belongs, the three-fusion HSS to which the user of the called end belongs forwards the routing request information of the short messages to an IP-SM-GW of a calling end, and the IP-SM-GW of the calling end asks the three-fusion HSS to which the user of the calling end belongs for the short message routing information of the calling end at 2G, and then returns the short message routing information to the short message center to indicate the short message center to send a Mobile Terminated (MT) short message to the IP-SM-GW of the calling end; after receiving an MT short message, an IP-SM-GW of a calling terminal tries to send the short message carrying a network link address to a user of the calling terminal in an IMS domain in an IMS IP short message mode, and if a user of a Long Term Evolution Voice service (VoLTE, Voice over Long Term Evolution) of the calling terminal resides in a Time-sharing Long Term Evolution (TD-LTE, Time Division Long Term Evolution) network, the sending success of the short message is indicated; if the VoLTE user of the calling terminal resides in the 2G network, the short message sent by the IP-SM-GW in the IMS IP short message mode is failed, and the IP-SM-GW sends the short message carrying the network link address to the user of the calling terminal in the circuit domain short message mode through the signaling network by using the obtained short message routing information of the user of the calling terminal in the 2G network. Here, the triple-convergence HSS to which the user belongs refers to a combination of a Home Location Register (HLR), an IMS-HSS, and a System Architecture Evolution-Home subscription server (SAE-HSS).

After receiving a short message carrying a network link address sent by a called end in a VoLTE call process, a user of a calling end can select to click the network link address to trigger an internet access service. For example, when the calling end identifies a network link address or inputs the network link address, i.e. a Uniform Resource Locator (URL), in the browser, the calling end will access the Http Server. The calling end constructs a Domain Name System (DNS) query message, queries a host IP corresponding to a URL of a WEB site to be accessed, obtains the IP of the WEB site, constructs an IP message, transmits the IP message to a PGW/GGSN through a data carrying channel, and then routes the IP message to the WEB site to realize internet surfing. The GET URL and RESPONSE refer to application layer messages, and are transmitted by being encapsulated in an IP message.

The method for implementing the internet access service based on the long term evolution voice call provided by the above embodiments is generally applied to a serving call session control function entity, after acquiring the call response message responded by the called terminal to the voice call setup request initiated by the calling terminal, acquiring a short message carrying a network link address matched with the identification of the calling terminal and the identification of the called terminal in a triggering mode, so that the opposite end of the conversation side where the service call session control function entity is located can realize the internet surfing service by triggering the network link address in the short message, compared with the method of manually editing the short message with the network link address and sending the short message in a manual triggering mode, the method has high efficiency and good flexibility, and the calling end and/or the called end can realize surfing the internet based on the short message carrying the network link address sent by the opposite end in the conversation process or after the conversation is finished.

In a specific embodiment, before step 101, the method may further include:

Specifically, the S-CSCF downloads, from the HSS, service subscription data corresponding to a home terminal of a call side where the S-CSCF is located, where the service subscription data includes a user identifier and a service signed by a user corresponding to the user identifier, and is used to determine whether the user has signed a service provided by the AS; when the S-CSCF determines that the local terminal has signed the service provided by the AS according to the service signing data, the S-CSCF sends a third party registration request message to the AS so that the AS carries out user authentication and authentication on the local terminal; and the S-CSCF receives a response message which is sent by the AS after responding to the third party registration request message and carries a user authentication and authentication result, if the user authentication and authentication result shows that the AS successfully authenticates and authenticates the user of the home terminal, the home terminal has the authority of using the service provided by the AS, and if the user authentication and authentication result shows that the AS fails in authentication and authentication of the user of the home terminal, the home terminal does not have the authority of using the service provided by the AS.

Here, the third party registration request message is sent to the AS by the S-CSCF instead of the user to request the AS to determine whether the user has the right to use the service provided by the AS, and the third party registration request message may include user data such AS user identity data and service subscription data; and the AS judges whether the user has the authority to use the service provided by the AS based on the third party registration request message, namely the user authentication is carried out. When the AS successfully authenticates the user authentication of the home terminal, the response message may be a 200OK message carrying the user authentication result.

In this way, the serving call session control function entity initiates a third party registration to the application server in advance, so that the application server can be directly triggered to provide a corresponding service.

In order to implement the foregoing method, this embodiment further provides an apparatus for implementing an internet access service based on a long term evolution voice call, where as shown in fig. 2, the apparatus includes: a first transmitting unit 10, a first receiving unit 11 and a second transmitting unit 12; wherein the content of the first and second substances,

The first sending unit 10 is specifically configured to: after receiving a call response message responded by a called terminal aiming at a voice call establishment request initiated by a calling terminal, sending a trigger instruction carrying an identifier of the calling terminal and an identifier of the called terminal to an AS so AS to trigger the AS.

After the called end receives the voice call establishment request sent by the calling end and responds to the call response message, the call response message is firstly sent to the S-CSCF to which the called end belongs, then the S-CSCF to which the called end belongs is sent to the S-CSCF to which the calling end belongs, and finally the S-CSCF to which the calling end belongs is sent to the calling end; the call answer message may be an off-hook 200ok (invite) message. The AS has the function of acquiring a corresponding network link address from a database according to the identification of the calling end and the identification of the called end and generating a short message carrying the network link address, and the service provided by the AS is the 'and color chain' service, for example, the service of pushing the short message carrying the network link address which is self-defined by the user at the end and matched with the user at the opposite end to the user at the opposite end based on the triggering of the calling end or the called end in the VoLTE call process.

Here, AS an alternative embodiment, when both the calling terminal and the called terminal have signed the "sum chain" service provided by the AS, an S-CSCF to which only the called terminal or the calling terminal belongs may be set to trigger the AS. That is, before the first receiving unit 11 sends the trigger instruction to the AS, iFC matching detection may be further required, and the first receiving unit 11 is allowed to send the trigger instruction to the AS only when the trigger condition is met. For example, when the "and color chain" service set in the iFC can only be triggered by a called party, the first receiving unit 11 may send a trigger instruction to the AS only when the home terminal of the call side where the S-CSCF is located is the called terminal, that is, the trigger condition is satisfied.

In this embodiment, the identifier is taken as a mobile phone number of a user, that is, the identifier of the calling terminal is taken as a mobile phone number of a calling user, and the identifier of the called terminal is taken as a mobile phone number of a called user.

Step 202: and based on the trigger instruction, extracting a network link address matched with the identification of the calling terminal and the identification of the called terminal from a database, and generating a short message carrying the network link address.

Specifically, the AS performs matching search in a database based on the identifier of the calling terminal and the identifier of the called terminal carried in the trigger instruction received in step 201; when the home terminal of the calling side where the S-CSCF is located is a calling terminal, the AS determines a network link address matched with the identification of the called terminal from a network link address set matched with the identification of the calling terminal; and/or when the local terminal of the calling side where the S-CSCF is located is a called terminal, determining a network link address matched with the identifier of the calling terminal from a network link address set matched with the identifier of the called terminal.

Here, the database may be preset. For example, the user a may set, in a set database, an internet link www.baidu.com that will be triggered when the user a is a calling party and the user B is a called party, so that the set database records internet link information that the mobile phone number of the user a and the mobile phone number of the user B correspond to a calling-called relationship; when the user A is used AS a calling party to call the user B based on the mobile phone number, the S-CSCF to which the calling party belongs triggers the AS to call data in the set database by taking the mobile phone number of the user A and the mobile phone number of the user B AS input information, and the internet link with the output of www.baidu.com can be obtained.

Here, when the home terminal of the call side where the S-CSCF is located is a calling terminal, the determining, by the AS, a network link address matching the identifier of the called terminal from a network link address set matching the identifier of the calling terminal includes: determining an attribute relationship between the called terminal and the calling terminal based on the identification of the called terminal; and matching and searching in the network link address set according to the attribute relationship to obtain the network link address corresponding to the attribute relationship. The attribute relationship between the calling terminal and the called terminal may be regarded as a relationship between a user of the calling terminal and a user of the called terminal, for example, the user of the called terminal is a friend, a relative, a client, or the like of the user of the calling terminal. For example, the user a performs attribute setting on a plurality of mobile phone numbers in a set database, for example, sets the plurality of mobile phone numbers as a family group, a colleague group, a friend group, a client group, and the like, and can set different internet links for different attribute groups. If the mobile phone number of the user B is in the friend group set by the user A, when the user A is used AS a calling party to call the user B based on the mobile phone number, the S-CSCF to which the calling party belongs triggers the AS to call data in the set database by taking the mobile phone number of the user A and the mobile phone number of the user B AS input information, and the acquired internet link corresponding to the friend group of the user A is used AS the internet link matched with the mobile phone number of the user A and the mobile phone number of the user B.

Here, when the home terminal of the call side where the S-CSCF is located is a called terminal, determining a network link address matching the identifier of the calling terminal from a network link address set matching the identifier of the called terminal includes: determining an attribute relationship between the calling terminal and the called terminal based on the identification of the calling terminal; and matching and searching in the network link address set according to the attribute relationship to obtain the network link address corresponding to the attribute relationship. For example, the user B sets the attribute of each of the plurality of mobile phone numbers in the set database, for example, sets the plurality of mobile phone numbers as a family group, a colleague group, a friend group, a client group, and the like, and can set different internet access links for different attribute groups. If the mobile phone number of the user A is in the client group set by the user B, when the user A is used AS a calling party to call the user B based on the mobile phone number, the S-CSCF to which the called party belongs triggers the AS to call data in the set database by taking the mobile phone number of the user A and the mobile phone number of the user B AS input information, namely, in the network link address set matched with the mobile phone number of the user B, the internet link corresponding to the client group of the user B is used AS the internet link matched with the mobile phone number of the user A and the mobile phone number of the user B.

Step 203: and sending the short message carrying the network link address to the service call session control function entity.

Specifically, the AS sends the short message carrying the network link address generated in step 202 to the S-CSCF to complete the response to the trigger instruction sent by the S-CSCF in step 201.

The method for implementing internet surfing service based on long term evolution voice call provided by the embodiment is generally applied to an application server, and the short message carrying the network link address is generated by extracting the network link address matched with the identifier of the home terminal and the identifier of the opposite terminal of the call side where the service call session control function entity is located from a set database by responding to a trigger instruction sent by the service call session control function entity, so that the corresponding network link address can be automatically acquired according to the identifier of the home terminal and the identifier of the opposite terminal of the call side where the service call session control function entity is located, and the short message carrying the network link address is automatically generated, so that the internet surfing service based on the long term evolution voice call technology is high in efficiency and good in flexibility.

In a specific embodiment, before step 201, the method may further include:

Specifically, the AS receives a third party registration request message sent by the S-CSCF based on the confirmation that the home terminal of the call side where the S-CSCF is located signs the service provided by the AS, so AS to request the AS to perform user authentication and authentication on the home terminal of the call side where the S-CSCF is located; and the AS sends a response message containing a user authentication result to the S-CSCF after carrying out user authentication based on the third party registration request message.

The following description is made of a third party registration process initiated to the AS after the home terminal of the call side where the S-CSCF is located is powered on and attached to the LTE network and the IMS default bearer is established, specifically AS follows: the S-CSCF sends a REGISTER REGISTER message to the AS, when the AS finds that the Data of the User does not exist in the local database according to the REGISTER REGISTER message, the AS sends a User Data Request (UDR) message to the fused HLR/HSS so AS to Request to acquire User Data including User identity Data, service signing Data and other Data, and the HSS returns a message carrying a User Data response (UDA, User Data Answer); and the AS carries out authentication and authorization on the user of the local end of the calling side where the S-CSCF is located according to the received user data, stores the user data into a local database after the authentication and authorization is passed, and finally returns a 200OK successful response message registered by the third party to the S-CSCF.

Therefore, after the application server successfully authenticates and authenticates the user of the home terminal of the call side where the service call session control function entity is located, the user has the authority to use the service provided by the application server.

For example, the user a may set, in a set database, an internet link www.baidu.com that will be triggered when the user a is a calling party and the user B is a called party, so that the set database records internet link information that the mobile phone number of the user a and the mobile phone number of the user B correspond to a calling-called relationship; when the user a is used as a calling party to call the user B based on the mobile phone number, the S-CSCF to which the calling party belongs triggers the processing unit 21 to call data in the set database by using the mobile phone number of the user a and the mobile phone number of the user B as input information, and an internet link with an output of www.baidu.com can be obtained.

Here, when the home terminal of the call side where the S-CSCF is located is a calling terminal, the determining, by the processing unit 21, a network link address matching with the identifier of the called terminal from a network link address set matching with the identifier of the calling terminal includes: determining an attribute relationship between the called terminal and the calling terminal based on the identification of the called terminal; and matching and searching in the network link address set according to the attribute relationship to obtain the network link address corresponding to the attribute relationship. The attribute relationship between the calling terminal and the called terminal may be regarded as a relationship between a user of the calling terminal and a user of the called terminal, for example, the user of the called terminal is a friend, a relative, a client, or the like of the user of the calling terminal. For example, the user a performs attribute setting on a plurality of mobile phone numbers in a set database, for example, sets the plurality of mobile phone numbers as a family group, a colleague group, a friend group, a client group, and the like, and can set different internet links for different attribute groups. If the mobile phone number of the user B is in the friend group set by the user a, when the user a calls the user B based on the mobile phone number as the calling party, the S-CSCF to which the calling party belongs triggers the processing unit 21 to call data in the set database by using the mobile phone number of the user a and the mobile phone number of the user B as input information, and the obtained internet access link corresponding to the friend group of the user a is used as the internet access link matched with the mobile phone number of the user a and the mobile phone number of the user B.

Here, when the home terminal of the call side where the S-CSCF is located is a called terminal, the determining, by the processing unit 21, a network link address matching the identifier of the calling terminal from a network link address set matching the identifier of the called terminal includes: determining an attribute relationship between the calling terminal and the called terminal based on the identification of the calling terminal; and matching and searching in the network link address set according to the attribute relationship to obtain the network link address corresponding to the attribute relationship.

Example four

The following describes the embodiment in further detail by using a specific example, where the implementation function of the internet service based on the VoLTE call is defined as a "sum color chain" service function, fig. 6 is a specific structural diagram of an implementation system of the internet service based on the VoLTE call, and based on the system shown in fig. 6, the main process of the implementation method of the internet service based on the VoLTE call includes:

firstly, a VoLTE user in an LTE network completes EPC network attachment and then registers to an IMS core network, so that the VoLTE network has internet access service capability and VoLTE voice service capability. And the S-CSCF downloads the subscription data from the HSS, and judges that the VoLTE user has subscribed the services of 'and color chain' according to the iFC subscription information, so that the S-CSCF initiates third-party registration to the service AS of 'and color chain'.

Secondly, when a VoLTE calling terminal (UE) dials a VoLTE called UE, an INVITE message of the voice Call establishment request is sent to a Session Border Controller (SBC) of the IMS core Network via an eNodeB of the LTE wireless Network and a Serving GateWay (SGW) of the EPC core Network/a Packet Data GateWay (PGW), a Proxy Call Session Control Function (P-CSCF), and then sent to the S-CSCF in the IMS domain.

At this time, the S-CSCF of the IMS core network of the calling side is routed to an inquiring Call Session Control Function entity (I-CSCF) of the IMS core network of the called side according to the information of an ENUM (Telephone Number Mapping working group)/DNS (Domain name Server), the I-CSCF to which the called side belongs and an HSS (home subscriber Server) interact LIR/LIA to determine the S-CSCF registered by the called UE, the Call is routed to the S-CSCF to which the called side belongs, and the S-CSCF to which the called side belongs routes the Call to the SBC/P-CSCF and is connected to the called UE. After completing the INVITE message confirmation of the voice call establishment request between VoLTE calling UE and called UE, the called UE and the calling UE complete the codec negotiation and resource reservation through 183RINGING/PRACK/UPDATE/200_ OK message, then the called UE sends 180RINGING message and 200OK (INVITE) response message to the calling UE, and starts the conversation between the calling UE and the called UE.

If the VoLTE called user sends 200OK (INVITE) off-hook information, at the moment, the S-CSCF triggers a 'and color chain' service AS, the 'and color chain' service AS calls user-defined internet link content in a third-party platform database according to the information of the calling number, the called number and the like AS judgment conditions, and the 'and color chain' service AS generates a short message with internet link. The third-party platform database mainly realizes the internet link content setting of the VoLTE user-defined short message, if an individual user can set different push links for friend numbers with different attributes, and an enterprise user can set advertisement push links for target users.

Short messages with network connection are forwarded between VoLTE users through an IP-SM-GW short message gateway so as to be pushed to an opposite end user. The short message pushing process is the same as the existing standard short message pushing process, except that the pushed content is a short message with a self-defined internet link. The short message with the internet link refers to a website link address which is established in the mobile internet and is specially used for internet browsing of a mobile phone and is added into a common short message, so that the information carrying capacity of the short message is expanded, and the display content of the common short message is enriched.

And finally, after the call is established, the VoLTE calling party or the called party receives a short message carrying the Internet link and sent by the opposite-end user, the Internet link in the short message can be clicked to trigger the Internet service in the call process or after the call is finished, and the flow of the subsequent Internet service is the same as that of the existing standard Internet service.

In summary, the implementation method of the internet access service based on the VoLTE call mainly needs to go through four flows, such as a registration flow, a session flow, a short message flow, and an internet access flow, where each flow is specifically described as follows:

first, registration process

When the terminal is powered on or visits the network for the first time, the EPC network attachment is completed through the LTE network, where a specific process of the EPC network attachment is shown in fig. 7, and a Mobility Management Entity (MME) reports a network VoLTE support capability to the HSS when a location is updated, and obtains user data such as a Session Transfer Number-Single Radio (STN-SR), a user Number of a user in a circuit switched domain (C-MSISDN), and the like. After the EPC is attached, the MME initiates a CMNET APN default bearer establishment request (APN ═ CMNET, QCI ═ 9) to a Serving Gateway-Packet Data Network Gateway (SAE-GW), completes establishment of a Data default bearer, and the user can access the Internet.

The process of establishing the data default bearer specifically includes the following steps:

step 1.1: the UE sends an Attach Request (Attach Request) message to the MME; wherein, the attach request message includes the identity information of the UE, the attach request type, and other information.

Step 1.2-1.3: after receiving the Attach Request message sent by the UE, the MME sends an Authentication Request (AIR) message to the converged HSS, and receives an Authentication response (AIA) message returned by the converged HSS.

Step 1.4-1.5: the MME sends an Authentication Request message to the UE and receives an Authentication Response message returned by the UE after responding to the Authentication Request message.

Step 1.6-1.7: the MME sends a Location Update Request (Update Location Request) message to the convergence HSS, and receives a Location Update response (Update Location Ack) message returned after the convergence HSS completes Location registration of the user.

Step 1.8-2.1: after receiving a Create bearer Request (Create Session Request) message containing a PGW address sent by an MME, an SGW sends the Create Session Request message to the PGW to Request for creating a default bearer; the PGW sends a Credit Control Request (CCR) message to the PCRF so as to apply for establishing a Control rule of an Evolved Packet System (EPS) default bearer, and receives a Credit Control response (CCA) message which is returned by the PCRF and contains the Control rule for establishing the EPS default bearer; after the PGW creates an EPS default bearer, a Create bearer Response (Create Session Response) message is returned to the SGW, and the SGW returns the Create Session Response message to the MME.

Step 2.2: after receiving the Create Session Response message, the MME sends an Attach Accept (Attach Accept) message to the UE, and completes the data default bearer establishment procedure.

The terminal identifies that the network supports VoLTE, after the data bearer is established, an IMS APN default bearer establishment request (APN is IMS, QCI is 5) is initiated to the network, the establishment of the IMS default bearer is completed, and the PDN-GW/SAE-GW returns the IP address of the SBC/P-CSCF, namely the entrance address of the IMS domain to the UE according to the SBC dynamic selection strategy.

The IMS default bearer establishment process specifically includes:

step 2.3: after receiving an Attach Accept message sent by an MME, UE sends a packet data network connection Request (PDN Connectivity Request) message to the MME;

step 2.4-2.7: the MME sends a Create Session Request message to the SGW, and the SGW sends the Create Session Request message to the PGW to Request the establishment of a default bearer after receiving the Create Session Request message sent by the MME; the PGW sends a CCR message to the PCRF to apply for establishing a control rule of the EPS default bearer, and receives a CCA message which is returned by the PCRF and contains the control rule for establishing the EPS default bearer; after the PGW creates EPS default bearer, a Create Session Response message is returned to the SGW, and then the SGW returns the Create Session Response message to the MME.

Step 2.8: after receiving the Create Session Response message, the MME sends a packet data network connection Response (PDN Connectivity Response) message to the UE, thereby completing the IMS default bearer establishment procedure.

After receiving the IP address of the SBC/P-CSCF, the VoLTE terminal initiates an IMS domain registration request message to realize the support of the IMS domain on subsequent call control and service capability. The IMS domain registration request message includes an IMPI derived from a Universal Subscriber Identity Module (USIM) and a corresponding IMPU. As shown in fig. 8, the IMS registration procedure specifically includes the following steps:

step 3.1-3.6: UE sends Register request (Register) message to P-CSCF, P-CSCF sends Register message to S-CSCF through I-CSCF; the S-CSCF sends a Multimedia Authentication Request (MAR) message to the converged HSS, and after receiving a Multimedia authentication Request (MAA) message carrying authentication data returned by the converged HSS, the S-CSCF issues the authentication data to the UE through a 401 message so that the UE completes network authentication, thereby completing initial registration.

Step 3.7-3.12: after receiving the Register message carrying the authentication response returned by the UE, the S-CSCF sends a Server Assignment Request (SAR) message to the converged HSS, receives a Server Assignment response (SAA) message carrying user subscription data returned by the converged HSS, and then sends a 200OK message carrying successful authentication to the UE, so as to complete authentication of the UE by the network side.

Step 3.13-3.14: and the S-CSCF sends a Register message of third party registration to the AS, and after receiving a 200OK message responded by the AS aiming at the Register message of the third party registration, the success of the third party registration is shown.

Here, based on the user subscription data downloaded from the HSS, the S-CSCF initiates third-party registration to the VoLTE AS integrated with the MMTEL AS/SCC AS/IP-SM-GW function and the "and color chain" service AS according to iFC in the user subscription data, and prepares for subsequent third-party service triggering.

Here, the implementation system of the internet service based on the VoLTE call needs to deploy the existing network service AS and the color chain service AS and the third party platform database, the HSS needs to sign a contract for the user and the color chain iFC ID, and the S-CSCF needs to newly add data configuration of the color chain and the color chain iFC, and the specific instructions are AS follows:

(1)ADD SIFCTPL：

SIFC TPLID ═ 600, TPL NAME ═ LMSS _ AS _ Shared _ IFC, COMMENT ═ called and colorchain,;

(2)ADD SIFCTPL：

SIFC TPLID ═ 500, TPLNAME ═ LMSS _ AS _ Shared _ IFC, commune ═ calling and color chains;

the ADD SIFCTPL command, among other things, functions to configure a template for the iFC data.

Second, conversation process

As shown in fig. 9, the session flow specifically includes the following steps:

step 4.0-5.1: UE initiates a call in an LTE coverage area, a call request (INVITE) message is sent to an IMS through an EPC network, an S-CSCF in an IMS core network is triggered to a VoLTE AS according to iFC information, and a calling side AS provides calling service for the UE. And after finishing the AS trigger of the calling side, the calling side S-CSCF sends an ENUM/DNS query request to the ENUM/DNS to obtain an I-CSCF of the called side, and the call is connected to the IMS network of the called side. An AS in the IMS network of the called side provides called services for called UE, then the selection of the called access domain is completed according to the selection information of the called access domain selection (T-ADS), and the S-CSCF of the called side connects a call request (INVITE) message to the called UE through the called EPC network and the LTE access network according to the selection result of the domain.

Step 5.2-5.9: after completion of INVITE message confirmation between VoLTE calling UE and called UE, media negotiation and resource reservation are completed between called UE and calling UE through 183/PRACK/UPDATE/200_ OK message, then called UE sends 180Ringing message to calling UE, and the transfer path of 180Ringing message is: called UE, EPC to which the called UE belongs, P-CSCF to which the called UE belongs, S-CSCF to which the called UE belongs, AS, S-CSCF to which the called UE belongs, I-CSCF to which the called UE belongs, S-CSCF to which the calling UE belongs, AS, S-CSCF to which the calling UE belongs, P-CSCF to which the calling UE belongs, EPC to which the calling UE belongs, and calling UE. In the figure, a behind capital letters is indicated as calling side, and b is indicated as called side; for example, UEa denotes a calling UE, and UEb denotes a called UE. After receiving the 180Ringing message sent by the called UE, the calling UE returns an ACK response message to the called UE, and the transmission paths of the ACK response message are as follows in sequence: the method comprises the steps of calling UE, EPC to which the calling UE belongs, P-CSCF to which the calling UE belongs, S-CSCF to which the calling UE belongs, AS, S-CSCF to which the calling UE belongs, I-CSCF to which the calling UE belongs, S-CSCF to which the called UE belongs, AS, S-CSCF to which the called UE belongs, P-CSCF to which the called UE belongs, EPC to which the called UE belongs, and called UE. Finally, the called UE sends 200_ OK off-hook information to the calling UE, and the VoLTE users start to talk.

Third, short message flow

As shown in fig. 10, the short message process specifically includes the following steps:

step 6.0: after receiving a 200OK off-hook message returned by a called UE responding to a call establishment request (INVITE) message, the S-CSCF triggers a 'and color chain' service AS by sending the INVITE message to the 'and color chain' service AS;

step 6.1-6.4: and the 'and color chain' service AS calls user-defined internet link information from a third-party platform database, generates a short message carrying the internet link and returns the short message to the S-CSCF. And the S-CSCF sends a short message containing the customized Internet link to the opposite terminal UE. Here, the short message push process specifically includes: the sending end S-CSCF sends the short message to the sending end IP-SM-GW, and the short message is sent to the SMSC through the signaling network. SMSC inquires short message routing information to the three-convergence HSS of the receiving terminal user home. And the receiving end user attribution three-fusion HSS forwards the short message routing request message to a receiving end IP-SM-GW, and the receiving end IP-SM-GW asks the receiving end user attribution three-fusion HSS for the short message routing information of the receiving end user in 2G and then returns the short message routing information to the SMSC to indicate the SMSC to send the MT short message to the receiving end IP-SM-GW. After receiving MT short messages, the IP-SM-GW of the receiving end tries to send short messages carrying internet links to users in an IMS domain in an IMS IP short message mode, and if a VoLTE user of the receiving end resides in a TD-LTE network, the receiving end indicates that the short messages are successfully sent; if the receiving end VoLTE user resides in the 2G network, the short message sent by the IP-SM-GW in the IMS IP mode fails, and the IP-SM-GW sends the short message carrying the internet link to the user in the circuit domain short message mode through the signaling network by using the obtained short message routing information of the user in the 2G network.

Fourth, Internet access process

As shown in fig. 11, the internet surfing process specifically includes the following steps:

step 7.0-7.4: in the VoLTE call, the user receives a short message containing an Internet link sent by the opposite terminal, and can select to click the Internet link to trigger an Internet service. After the VoLTE user terminal identifies the Internet link or inputs the URL address of the Internet link in the browser, the UE accesses the Http Server. Because the UE establishes the default bearer of the data channel between the successful attachment of the EPC network and a PGW/General Packet Radio Service (GGSN), the UE sends a DNS Query message carrying the URL to the DNS and receives a DNS Response message carrying the IP corresponding to the URL returned by the DNS, thereby obtaining the host IP corresponding to the URL of the WEB site to be accessed. After the WEB site IP is obtained, the UE constructs an IP message, transmits the message to the PGW/GGSN through a data bearing channel, and then routes the IP message to the WEB site. The GET URL and RESPONSE refer to application layer messages, and are transmitted by being encapsulated in an IP message.

In summary, in this embodiment, the internet service based on the VoLTE call is implemented by the existing network TAS and the third-party service platform, after the VoLTE user call is established, the S-CSCF triggers the service AS to call the third-party platform database to generate a short message carrying the user-defined internet link, and push the short message to the opposite-end user, so AS to guide the opposite-end user to click the internet link in the short message to trigger the internet service. Therefore, the method and the system provided by the embodiment can effectively expand the capability of the IMS core network and the VoLTE service, and the VoLTE voice is used as the leading entrance of the internet service, so that the traffic income of service operation can be increased, and the method and the system can also be used as the propaganda highlight point of the VoLTE service, thereby highlighting the technical advantages of the VoLTE network.
