Technical field

The present invention relates to the field of communications, and in particular, to a service processing method, system, and application server. Background technique

At present, with the maturity of packet technology, traditional telecommunication networks based on circuit switching are developing toward packet-switched broadband telecommunication networks, which are generally referred to as NGN (Next Generation Network) and use sessions. The SIP (Session Initiation Protocol) is one of the current technological development trends as the call control signaling of the NGN core network. For example, the Internet Multimedia Subsystem (IMS) network, IMS is the third generation mobile communication standardization. An IP Multimedia Subsystem defined by the 3GPP (3rd Generation Partnership Project) standard is a third-generation (3G, 3rd Generation) mobile network that implements packet voice and packet data to provide a unified multimedia service and application target network.

Many of the services provided in traditional telecommunication networks can also be provided by IMS networks, such as call hold and call waiting services.

Call hold means that if user A subscribes to the call hold service, when user A makes a call with user B, if user A needs to suspend the call temporarily, but the call may be resumed after a short time, the user A does not need to end the call, but just press the button to enter the call hold state, then user B will hear the call hold tone played by user A, for example, "You are in the call hold state, if you need to continue talking with the other party, please do not Hang up the phone", when user A can continue to talk with user B, press the button again to resume the call.

Call waiting means that if user A signs up for call waiting service, user A is working with user B. During the call, user C tries to establish a call connection with user A. Then A user will hear the prompt tone of the system, indicating that another user is currently calling the local machine. If user A cannot temporarily answer the call of user C, but If you can answer the call in a short time, user A can press button to let user C enter the call waiting state. At this time, user C will hear the call waiting tone played by the system, for example, "You are in the call waiting state, if you need to continue calling the other party, Do not hang up the phone. When User A can answer the call from User C, press to select the answering call.

However, in the above service, if the service participant is not a user, but an automatic answering device, such as a voice mail server or an automatic answering machine, if the system plays voice to the device, it will cause waste of network resources. .

The processing unit 503 is configured to perform corresponding processing on the service according to the determination result. For example, when the judgment result of the determining unit is that the service participant is an automatic answering device, part of the rejection or all rejection is automatic. The business in which the business participants of the responding device participate.

The processing unit 503 includes: a service application processing unit 5031, and may further include a service application object conversion unit 5032.

The business application processing unit 5031 is for rejecting the business involved for the business participants of the automatic answering device.

The service application object conversion unit 5032 is configured to convert the application object of the rejected service into a service participant of the non-automatic answering device, and perform service processing.

The service information recording unit 5033 is configured to record the business information of the rejected service when the service is rejected.

The service information transmitting unit 5034 is configured to send the service information to a service participant that is a non-automatic answering device.

It can be seen that the user agent capability parameter is an important parameter for performing service processing. As described above, the SIP user agent capability parameter can be obtained from the SIP message sent by the user terminal, but in practical applications, the user terminal may not have The ability to carry the SIP user agent capability parameter in the sent SIP message Force, or the user terminal may not have the ability to send SIP messages. In this case, a network entity needs to add the SIP user agent capability parameter to the SIP message for subsequent application processing by the application server. The specific steps are as follows:

Step 1: The first network element receives the SIP message sent by the user terminal, and determines that the SIP user agent capability parameter is not carried in the SIP message, and generates a SIP user agent capability parameter and adds the SIP user agent to the SIP message.

Step 2: The second network element receives the SIP message sent by the first network element, and performs corresponding service processing according to the SIP user agent capability parameter carried in the SIP message, such as service triggering and service logic control.

The manner in which the first network element adds the SIP user agent capability parameter to the SIP message is as follows: Mode 1: The user terminal does not have the capability of carrying the SIP user agent capability parameter in the sent SIP message, and receives the SIP message. A network element analyzes the content of the SIP message, or obtains the attribute of the sender or receiver of the SIP message according to preset information such as the user subscription information, and generates a corresponding SIP user agent capability parameter. For example, the first network element receives a SIP message and analyzes the called number. For example, the called number in the Request-URI is "800", so that the attribute of the recipient is "freephone," and the corresponding number is generated. SIP user agent capability parameter, adding Caller Preferences in the sent SIP message is "freephone", that is, the SIP user agent capability parameter indicating the attribute of the receiver, that is, the service attribute used by the sender; The Request-URI carries the called number "166". After the first network element analyzes that the recipient's attribute is "voice mailbox access code", the corresponding SIP user agent capability parameter is generated, and the SIP message is sent. The caller preference (Caller Preferences) is an "automatic answering device"; for example, after receiving the SIP message, the first network element triggers the SIP message to the server that processes the PoC service according to the user subscription information, that is, the user subscription information It indicates that the attribute of the sender is "PoC", and the first network element generates a corresponding SIP user agent capability parameter according to this, and adds the user terminal to the sent SIP message. For example, the first network element processes the game service, receives the SIP message, and performs corresponding game service processing, that is, the service processing program itself indicates that the attribute of the receiver is "game", the first network element This generates a corresponding SIP user agent capability parameter, and the calling preference is added to the sent SIP message as "game".

Manner 2: The user terminal does not have the capability of carrying the SIP user agent capability parameter in the sent SIP message, and the first network element that receives the SIP message can be based on the terminal of the user terminal stored in the network. Force, generate the corresponding SIP user agent capability parameters. For example, in a network element, such as a server, the user terminal capability is saved, and the first network element obtains the terminal capability of the user terminal by sending a request message to the server, where the request message may be a query message, a SIP subscription message, or the like. The request message carries the identifier of the user terminal, such as the contact address, the device identifier, the private identifier, etc., and the server carries the terminal capability corresponding to the user terminal in the returned response message, and if the request message carries the user The identifier of the server, such as the public user identifier, the response message returned by the server carries the terminal capability of all terminals of the user and the identifier of the corresponding user terminal. Thereafter, when the first network element receives the SIP message sent by one terminal of the user, According to the identifier of the user terminal corresponding to the terminal, the terminal capability of the terminal is obtained.

Manner 3: The user terminal does not have the ability to carry the SIP user agent capability parameter in the sent specific SIP message. The first network element that receives the SIP message previously saves the SIP carried in the other specific SIP message sent by the user terminal. The user agent capability parameter, the first network element obtains the saved SIP user agent capability parameter. For example, the user terminal carries the SIP user agent capability parameter in the sent SIP registration message, and when the first network element receives the SIP registration message, the SIP user agent capability parameter carried in the message is saved, and thereafter, the user terminal sends the SIP. The SIP user agent capability parameter is not carried in the invitation message. After receiving the SIP invite message, the first network element adds the saved SIP user agent capability parameter corresponding to the user terminal to the SIP invite message.

Manner 4: The user terminal does not have the ability to send SIP messages. The first network element sends a SIP message instead of the user. The message carries the SIP user agent capability parameter of the user terminal. For example, the traditional terminal accesses the IMS through a first network element, and the first network element sends a SIP message, such as a SIP registration message, a SIP invitation message, or a SIP response code message, to the IMS network instead of the legacy terminal, and the message carries the traditional SIP user agent capability parameters of the terminal, such as "traditional terminal", "ISDN terminal", "POTS terminal", and the like.

In addition, in a case where the first network element obtains the terminal capability of the user terminal, the user terminal may initiate a subscription request to the first network element, for example, sending a SIP subscription message, where the first network element carries the corresponding message in the returned subscription notification message. After receiving the subscription notification message, the user terminal obtains the terminal capability, so that when the user terminal sends a SIP message, the corresponding SIP user agent capability parameter can be carried in the sent SIP message. In this case, when the user has more than one terminal, the subscription notification message received by one terminal of the user carries multiple terminal capabilities of the user and the identifier of the corresponding user terminal. At the same time, the terminal obtains the corresponding terminal capability according to the identity of its own user terminal.

It can be seen that the first network element adds the SIP user agent capability parameter of the SIP message sender or the receiver in the SIP message, or the user terminal adds the terminal capability obtained by subscribing to the first network element in the sent SIP message, and It is not limited to the foregoing processing of the automatic answering device to the service participant, but is applicable to various required scenarios. For example, the first network element adds the SIP user agent capability parameter of the legacy terminal to the SIP message for the second The network element performs corresponding service processing, for example, distinguishes the service processing of the legacy terminal and the IMS terminal; for example, the first network element adds a SIP user agent capability parameter to the SIP message, and the second network element performs corresponding call routing processing. Different terminal capabilities are routed in different directions.

The parameter adding unit 612 is configured to add the user agent capability parameter to the network element 61 to receive Issued in the Session Initiation Protocol message. The application server 62 is configured to perform business processing according to user agent parameters in the received session initiation protocol message.

The parameter generation unit 611 can generate corresponding user agent capability parameters in a variety of ways. For example, as shown in FIG. 6, a storage unit 613 and a storage unit are provided in the network element 61 for storing terminal capability information. In this way, the parameter generating unit 611 can generate a corresponding user agent capability parameter according to the terminal capability information of the sender and/or the receiver of the session initiation protocol message that does not carry the user agent capability parameter stored in the storage unit 613. For another example, the parameter generating unit 611 may further generate a corresponding user agent capability parameter according to the attributes of the sender and/or the receiver of the session initiation protocol message received by the network element 61. For example, the parameter generating unit 611 may further generate, according to the user agent capability parameter in the other session initiation protocol message sent by the sender and/or the sender of the session initiation protocol message that does not carry the user agent capability parameter received by the network element 61. User agent capability parameters.
