Description
Technical Field
The present invention relates to the field of mobile communications technologies, and in particular, to a method and an apparatus for implementing a call of a middle number service, and an electronic device.
Background
With the popularization and development of mobile communication services, the requirements of users for using mobile phones for contact in daily communication change rapidly, especially the requirements on protecting the privacy of both parties of a call, the call security, the call recording and the like are higher and higher, and China mobile launches a middle number service for third-party enterprise application in order to meet the requirements. The middle number service scene process is as follows: 1) allocating one or more virtual intermediate numbers X to a first user terminal A and a second user terminal B; 2) a first user terminal A calls and dials an intermediate number X allocated to the first user terminal A; 3) and the middle number X receives the incoming call of the A and is continuously connected to a second user terminal B, and the incoming call number displayed by the second user terminal B is the middle number X. The intermediate number service realizes information isolation between the calling party and the called party through one or more virtual intermediate numbers, protects identity information and number privacy of the calling party and the called party, and can realize customized function requirements of third-party enterprises, such as call recording, call state acquisition, early call playback, call connection playback and the like.
The scheme is that firstly, the incoming call request of the first user terminal A is forwarded to a playback media server M1, and customized playback is played to the first user terminal A through a playback media server M1. And after the playback is finished, the second user terminal B starts to be connected to play the called color ring, and after the second user terminal B is off-hook, the two parties start to talk. The specific interaction flow is as follows:
1) a first user terminal A dials an intermediate number X and sends an invite signaling to an application server AS;
2) after receiving the invite signaling of the first user terminal a, the application server AS forwards the invite signaling to the early playback media server M1;
3) the first user terminal A and the early playing media server M1 perform media negotiation and resource reservation;
4) the early stage playing media server M1 sends the media stream played in the early stage call to the first user terminal A, and the first user terminal A listens to the customized playing;
5) after the early-stage call playback is finished, the application server AS forwards the invite signaling of the first user terminal A to the second user terminal B;
6) if the second user terminal B signs the color ring back tone service, the invite signaling of the first user terminal A is forwarded to the color ring back tone media server M2, and the first user terminal A and the color ring back tone media server M2 perform media negotiation;
7) after the first user terminal A receives the 180 signaling of the second user terminal B, the color ring media server M2 sends a color ring media stream to the first user terminal A, and the first user terminal A listens to the color ring;
8) and the second user terminal B is off-hook, the first user terminal A receives the 200ok signaling of the second user terminal B, the first user terminal A and the second user terminal B carry out media negotiation, and the two parties start to talk after the negotiation is finished.
In the early conversation process from the call sending of the first user terminal A to the answering of the second user terminal B of the existing intermediate number service, the first user terminal A needs to perform media negotiation with the media server and the second user terminal B for many times, the signaling flow in the media negotiation process is complex, and the media negotiation process has the possibility of negotiation failure, which causes the risks of conversation establishment failure and call completing rate reduction.

Detailed Description
The embodiment of the invention provides a method and a device for realizing a call of a middle number service and electronic equipment.
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
AS shown in fig. 1, an embodiment of the present invention provides a call implementing method for an intermediary number service, where an execution main body of the method may be an Application Server (AS). The method may specifically comprise the steps of:
step S110, the application server receives a call request message from a first user terminal, wherein the call request message is used for requesting to realize the call between the first user terminal and a second user terminal through a middle number service.
When a calling user dials an intermediate number corresponding to a called user through a first user terminal, the first user terminal sends an invite signaling message, that is, a call request message, to an application server. For simplicity, in the following embodiments, the invite signaling message is taken as an example for illustration.
Step S120, the application server acquires a first address P1 and a second address P2 from a first media server according to the call request message; wherein the first address P1 and the second address P2 are communication addresses of the first media server.
Further, the step S120 includes:
after receiving a call request signaling message, the application server packages the media data of the first user terminal in the call request message into an address request message and sends the address request message to the first media server; the media data with the first user terminal may include a communication address Q1 of the first user terminal, including an IP address and a port of the first user terminal;
the first address P1 and second address P2 are received from the first media server.
The data transmission mode between the application server and the first media server may be various, for example, data transmission of http protocol may be adopted.
And the first media server records the communication address Q1 of the first user terminal according to the address request message, creates a new media session, and returns a first address P1 and a second address P2 to the application server, wherein the first address P1 and the second address P2 are communication addresses used by the first media server for data transmission with the second user terminal and the first user terminal respectively, namely the communication addresses of the first media server facing the second user terminal and the first user terminal respectively. The communication address may include an IP address and a port, etc.
Step S130, the application server executes a continuing operation to the second user terminal according to the first address P1 and the second address P2, and instructs the first media server to send a first media stream for playing customized playback to the first user terminal during the continuing operation, so that media interaction between the first user terminal and the second user terminal is realized through the first media server after the continuing operation is completed.
The application server identifies a Session Description Protocol (SDP) field in an invite signaling message acquired from the first user terminal, and identifies an IP address and a port opened by the first user terminal for receiving a Real-time Transport Protocol (RTP) stream in the SDP field, that is, a communication address Q1 of the first user terminal. And modifying the communication address Q1 of the first user terminal in the SDP field of the invite signaling message into a first address P1 distributed by the first media server, and then sending the modified invite signaling message to the second user terminal, thereby starting to execute the continuing operation to the second user terminal.
In one embodiment, during the execution of the continuing operation, the application server replaces the communication address Q1 of the first user terminal in a first signaling message sent by the first user terminal to the second user terminal with a first address P1, and replaces the communication address Q2 of the second user terminal in a second signaling message sent by the second user terminal to the first user terminal with a second address P2. The first signaling message and the second signaling message may include signaling messages used for media negotiation, various types of responses, and the like during a splicing operation.
The application server replaces the communication address Q1 of the first user terminal in the SDP field of the first signaling message received from the first user terminal with a first address P1, and then forwards the modified first signaling message to the second user terminal; the communication address Q2 of the second user terminal in the SDP field of the second signaling message received from the second user terminal is replaced with the second address P2, and the modified second signaling message is forwarded to the first user terminal.
During the execution of the continuing operation, the application server indicates the first media server to send a first media stream for playing the customized playback to the first user terminal, so that the ringing sound played by the first user terminal is replaced by the played customized playback.
When the second user terminal executes the answering operation, the 200-invite signaling message is sent to the application server, and the application server forwards the 200-invite signaling message to the first user terminal to complete the continuing operation, so that the first user terminal and the second user terminal can start to talk.
In the conversation process, media RTP streams which are transmitted by the first user terminal and the second user terminal in a media interaction mode are all transmitted to the first media server first and are forwarded by the first media server. In the process of forwarding the media RTP stream, the first media server may implement functions of intercepting, modifying, and recording the media RTP stream.
As can be seen from the above technical solutions provided by the embodiments of the present invention, in the embodiments of the present invention, a call request message is received from a first user terminal through an application server, where the call request message is used to request that a call between the first user terminal and a second user terminal is realized through a middle number service; the application server acquires a first address and a second address from a first media server according to the call request message; wherein the first address and the second address are communication addresses of the first media server; and the application server executes a continuing operation to the second user terminal according to the first address and the second address, and instructs the first media server to send a first media stream for playing customized playback to the first user terminal during the continuing operation, so that the media interaction between the first user terminal and the second user terminal is realized through the first media server after the continuing operation is finished. The embodiment of the invention realizes the playback and connection at the early conversation stage in the middle number service scene, optimizes the signaling interaction flow, reduces the signaling complexity and improves the conversation call completing rate.
Based on the foregoing embodiment, further as shown in fig. 2, the specific processing manner of the step S130 may be varied, wherein the step S130 adopts different processing manners according to whether the second user terminal signs up for the early session.
The early session may specifically be a color ring back tone service subscribed by the second user terminal, and for simplicity, the color ring back tone service is exemplified in the following embodiments.
In the case that the second user terminal does not subscribe to the color ring back tone service, the step S130 includes:
step S131, executing a media negotiation process between the first user terminal and the second user terminal according to the first address and the second address;
after receiving the invite signaling message sent by the application server, the second user terminal returns a response message to the invite signaling message, that is, a 183 signaling message. If the second user terminal does not sign the color ring back tone service, the SDP field of the 183 signaling message received by the application server will lack attribute information for indicating the color ring back tone service signed by the second user terminal, which may be sendrecv attribute specifically. The application server adds the sendrecv attribute in the SDP field of the 183 signaling message, modifies the communication address Q2 of the second user terminal in the SDP field of the 183 signaling message into a second address P2 allocated by the first media server, and forwards the modified 183 signaling message to the first user terminal to inform the first user terminal to play back according to the received media stream in the ringing phase.
After the application server receives the 183 signaling, the application server may further send the communication address Q2 of the second user terminal to the first media server for recording, so as to subsequently forward the media RTP stream sent to the second user terminal.
The continuing operation process comprises a media negotiation process between the first user terminal and the second user terminal, which is realized through the application server, wherein the media negotiation process comprises an update signaling message and a corresponding response signaling message which are forwarded through the application server. When the application server forwards each signaling message, the communication address Q1 of the first user terminal in the SDP field of each signaling message is replaced by the first address P1, and the communication address Q2 of the second user terminal is replaced by the second address P2.
Step S132, after receiving the ringing signaling message from the second user terminal, instructing the first media server to send a first media stream for playing customized playback to the first user terminal.
After the media negotiation between the first user terminal and the second user terminal is completed, the second user terminal sends a ringing signaling message, i.e. a 180 signaling message, to the first user terminal through the application server. And after receiving the 180 signaling message, the application server indicates the first media server to send a first media stream for playing customized playback to the first user terminal. And the first user terminal plays the customized playback according to the received first media stream. And sending a 200-invite signaling message to the first user terminal through the application server until the second user terminal executes an answering operation, completing the continuing operation, and enabling the first user terminal and the second user terminal to start a conversation.
As can be seen from the above technical solutions provided by the embodiments of the present invention, in the case that the second user terminal does not sign an early session, the embodiment of the present invention executes a media negotiation process between the first user terminal and the second user terminal according to the first address and the second address; and after receiving a ringing signaling message from the second user terminal, instructing the first media server to send a first media stream for playing customized playback to the first user terminal. The embodiment of the invention realizes the playback and connection at the early conversation stage in the middle number service scene, optimizes the signaling interaction flow, reduces the signaling complexity and improves the conversation call completing rate.
Based on the foregoing embodiment, as shown in fig. 3, in the case that the second user terminal signs up for an early session, the step S130 includes:
step S135, executing a media negotiation process between the first user terminal and a second media server according to the first address and the second address;
since the second user terminal signs the color ring back tone service, after receiving the invite message from the application server, the second user terminal forwards the invite message to the second media server M2 for implementing the color ring back tone service. And the second media server replies 183 signaling messages to the application server through the second user terminal according to the invite message, wherein the 183 signaling messages comprise sendrecv attributes. The application server modifies the communication address Q2 of the second user terminal in the SDP field of the 183 signaling message into a second address P2 and forwards the second address to the first user terminal.
The first user terminal and the second media server perform media negotiation through the application server, and the application server replaces the communication address Q1 of the first user terminal with the first address P1 and replaces the communication address Q2 of the second user terminal with the second address P2 in the SDP field of each signaling message in the media negotiation process.
Step S136, after receiving the ringing signaling message from the second user terminal, instructing the first media server to replace the second media stream for playing the early playback received from the second media server with the first media stream, and sending the second media stream to the first user terminal.
After the media negotiation between the first user terminal and the second media server is completed, the second user terminal sends 180 signaling messages to the first user terminal through the application server.
The second media server sends a second media stream for playing the color ring back tone to the first media server, and the first media server replaces the second media stream with the first media stream according to the indication of the application server and sends the second media stream to the first user terminal. And the first user terminal plays the customized playback according to the received first media stream.
Step S137, executing a media negotiation process between the first user terminal and the second user terminal according to the first address and the second address.
And after the transmission of the first media stream is finished, a media negotiation process between the first user terminal and the second user terminal is realized through the application server. And sending a 200-invite signaling message to the first user terminal through the application server until the second user terminal executes an answering operation, completing the continuing operation, and enabling the first user terminal and the second user terminal to start a conversation.
In an embodiment, as shown in fig. 4 and 5, a signaling interaction process in the case that the second user terminal signs a color ring back tone service according to the embodiment of the present application is as follows:
1. a first user terminal A dials an intermediate number X and sends an invite signaling message to an application server AS;
2. after receiving the invite signaling message of the first user terminal a, the application server AS encapsulates the media data of the first user terminal a in the SDP of the invite signaling message into an http-create request, and sends the http-create request to the first media server M3 to create a new media session, and the first media server M3 creates a session and returns http-200 including the IP addresses and ports of the first address P1 and the second address P2 of the session. After receiving the first address P1 and the second address P2 allocated by the first media server M3, the application server AS modifies an SDP field in an invite signaling message sent by the first user terminal a, specifically, identifies an SDP in the invite signaling sent by the first user terminal a, identifies an IP address and a port of a media layer in the SDP, then replaces the identified IP address and port of the media layer with the IP address and port of the first address P1 allocated by the first media server M3, and forwards the IP address and port to the network of the second user terminal B, thereby starting a connection operation.
3. If the second user terminal B signs the color ring back tone service, the invite signaling message of the first user terminal a will be forwarded to the second media server M2, and the first user terminal a and the second media server M2 will perform media negotiation through the application server AS. After receiving the 183 signaling message from the second media server M2, the application server AS replaces the media layer IP and port of the SDP in the 183 signaling message with the IP address and port of the second address P2 allocated by the first media server M3, and sends the replaced IP address and port to the first user terminal a. The first user terminal A and the second media server M2 finish the media negotiation of playing the color ring; the application server AS replaces the SDP media layer IP and port in the updata signaling message sent by the second media server M2 with the IP address and port of the second address P2 allocated by the first media server M3 and sends the IP address and port to the first user terminal A; replacing the media layer IP and the port of the SDP in the update signaling message of the first user terminal A with the IP address and the port of the first address P1 distributed by the first media server M3, and sending the IP address and the port to the second media server M2;
4. a first user terminal A receives a 180 signaling message of a second user terminal B;
5. the second media server M2 sends a second media stream for playing polyphonic ringtone to the first media server M3, and after receiving the second media stream of M2, M3 replaces the second media stream with the first media stream for playing customized playback and sends the first media stream to the first user terminal a, so that the first user terminal a plays the customized playback.
6. And after the customized playback is finished, the second user terminal B and the first user terminal A carry out media negotiation through the application server AS. Similar to the step 3, the application server AS replaces the media layer IP and the port of the SDP in the update signaling message of the second user terminal B with the IP address and the port of the second address P2 allocated by the first media server M3, and sends the IP address and the port to the first user terminal a, and the first user terminal a and the second user terminal B complete the media negotiation of the call;
7. the second user terminal B listens, the first user terminal a and the second user terminal B send media RTP streams of the call process to the first media server M3, the M3 forwards the media PRT stream from the first user terminal a to the second user terminal B, and forwards the media PRT stream from the second user terminal B to the first user terminal a, so that a and B start the call.
