Description

A method and device for message transmission in a multi-party call conference

technical field

The present invention relates to the technical field of wireless communication, in particular to a message transmission method and device in a multi-party call conference.

Background technique

An IP Multimedia System (IP Multimedia Subsystem, IMS) can support multimedia services and Internet applications on an IP multimedia platform. A high-definition call (Voice-over-LTE, VoLTE) runs on an IMS system, and is a voice solution under LTE.

The short number service is a convenient service in which users can dial a preset short number (for example: 608) instead of a multi-digit long number (for example: 12345760998) allocated by the operator. In the short number service, an intelligent network element on the network side (such as a short number platform) can convert the short number dialed by the user into a standard long number allocated by the operator and send it to the subsequent network element for calling. After the user has successfully signed a contract and set up the short number service, for example, user A corresponds to the short number 606, user B corresponds to the short number 607, and user C corresponds to the short number 608. Later, users A, B, and C perform paging, short message and other services , you can directly click the three-digit short number on the keyboard to perform corresponding paging, text messages, etc.

Multi-party calling is a value-added service. When a user signs up and activates this service, the user can set up a conference and add multiple users to participate in the conference. Usually, the process of establishing a multi-party call is as follows: a multi-party call subscriber first establishes a point-to-point call, then maintains the call, and calls another user at the same time. After the second call is established, the initiator merges the two calls. Merge into one conference, so that three users can communicate with each other. Conference subscription is a value-added service based on multi-party calls. Generally, users of the multi-party call component can subscribe to activate this function when signing up for the multi-party call service. Conference subscription is an independent business, as long as multi-party calls are supported, you can choose to activate the conference subscription function. A user with the conference subscription function will send a request to the server to obtain the status of all participating users in the multi-party call when establishing a multi-party call. After receiving the request, the server will feedback the status of each participating user through a status notification message . Wherein, the states of the participating users may include: calling, connected, hung up and other states. If the status of any participating user changes during the multi-party call, the server will notify the conference subscriber through a status update message.

If the users participating in the multi-party call have customized the short number service, they can directly dial the user's short number to establish a multi-party call and subscribe to the conference. For example: users A, B, and C subscribe to the short number service, and user A corresponds to the short number 606, user B corresponds to the short number 607, and user C corresponds to the short number 608. At the same time, user A has signed a multi-party call service right, and has the ability to subscribe to conferences and receive and process them. User A first dials the short number 607 of user B, and puts the call on hold after the call is established, so that user B is in a waiting state; at the same time, user A dials the short number 608 of user C again. After the call is established, user A clicks call merge on the interface, Successfully established a multi-party call between users ABC through traditional methods. After the conference is established, user A subscribes the conference status of the participants to the VoLTE conference AS by sending a SUBSCRIBE message, and the conference AS returns the standard 11-digit mobile phone numbers of participants B and C and their corresponding status parameters through the Notify message according to the actual situation (connect, disconnect, etc.), if other users join the conference, or the user leaves the conference, the conference AS will update the status to the conference subscriber (user A) through the Notify message again.

Although it is easy to implement multi-party calls through the short number service, when the user establishes a multi-party call through the short number, when obtaining the status of the participants, according to the existing technology, the network side returns the standard long number of the participating users, which causes the conference initiator Unable to identify and match the conference status of the displayed participants.

detailed description

In a multi-party call conference, as shown in Figure 1, the user who initiates the multi-party call can subscribe to the conference status of the participating users, and other participating users in the multi-party conference can also subscribe to the status of the participating users. The signaling interaction of subscribing to the state for participating in the conference is as follows, where the UE represents the initiator of the multi-party call conference, and the initiator requests the conference subscription as an example to describe in detail.

101. The UE sends a SUBSCRIBE message to a VoLTE conference server.

The subscription message requests to subscribe to the status (Conference StateEvent Packet) of each participating user in the multi-party conference call.

The request (Request-URI) field is carried in the SUBSCRIBE message, and the conference subscriber user fills in the user ID in the ConferenceURI field, for example, fills in the Conference URI as UE A,

102. The server receives a SUBSCRIBE message.

The server obtains the user ID as UEA in the Conference URI field of the SUBSCRIBE message.

103. The server replies a 200 OK message to the UE.

The 200OK message is used to confirm that the server has received the subscription message.

104. The server sends the status of each participating user to the conference subscriber UE through a Notify message according to the status of all participating users in the multi-party call conference.

According to the protocol, the server supports the elements and attributes in the Conference State Event Packet, including at least one of the following:

Conference information (Conference-info): conference entity (entity), maximum number of participants (Maximum-user-count), participating users (Users), conference initiator user (User): entity, Display-text, /Endpoint: entity, Status (supported values: connected, disconnected, on-hold) field.

The status of the participating users is expressed through the Status part in the Conference State Event Packet field of the Notify message.

Connected, disconnected, on-hold three parameters respectively indicate the status: answered, hung up, call on hold.

The meeting initiator user can send a SUBSCRIBE message to apply for the meeting subscription function to the server. Before the meeting ends, if the status of a participating user changes (for example, from connect to disconnect), the server needs to send a Notify message carrying the latest status of the user to the The conference subscriber (that is, the conference initiator).

With the introduction of the short number service, in a multi-party call conference, suppose user A establishes a multi-party call conference between user A, user B and user C by dialing the short numbers (607 and 608) of B and C; the multi-party call conference After the establishment, user A subscribes to the conference by sending a SUBSCRIBE message; the numbers corresponding to participants B and C in the received Notify status feedback message are long numbers, not the short numbers (607 and 608) used by the conference initiator during the dial-up phase , so that the conference initiator cannot identify and match the conference statuses of participants B and C.

When a user performs a call or other business through a short number, when the smart short number platform on the network side receives a call or business message containing a short number, the smart platform will, according to its internally stored long and short number correspondence table (or database), Carry out the conversion of input short number and output long number (11 is mobile phone number or 3-digit area code + 8-digit fixed-line number), and process all signaling containing short number as signaling containing only corresponding long number; and cannot complete short The inverse translation function of number to long number.

The server will return a Notify message, but participants B and C and the corresponding status fields use 3-digit short numbers, which will cause conference subscribers to fail to recognize and correctly display the user status after receiving this message;

The main realization principles, specific implementation methods and corresponding beneficial effects of the technical solutions of the embodiments of the present invention will be described in detail below with reference to each accompanying drawing.

Embodiment one

Embodiment 1 of the present invention proposes a message transmission method in a multi-party call conference, as shown in FIG. 2 , and its specific processing flow is as follows:

Step 21, determine whether the multi-party call conference is established by dialing a short number, and if the judgment result is yes, execute step 22. Otherwise, go to step 24.

Step 22, after it is determined that the multi-party call conference is established by dialing a short number, it is judged whether the state of the first participant user in the multi-party call conference changes. If the judgment result is yes, execute step 23; otherwise, end the process.

Step 23, if the state of the first participant in the multi-party call conference changes, send a Notify message for notifying the status of each participant in the multi-party call conference to the conference subscribing user.

The Notify message includes the status of the first conference user and the short number of the first conference user.

Wherein, the Notify message includes the corresponding relationship between the short number and the long number of the first participating user, wherein the long number is a unique identifier assigned by the operator to the first participating user.

Step 24, when it is determined that the multi-party call conference is not established by dialing a short number, and the state of the first participant in the multi-party call conference changes, send a message for notifying the status of each participant user of the multi-party call conference to the conference subscriber user Notify message.

The Notify message includes the status of the first participating user.

Optionally, after the status of the first participant user in the multiparty call conference changes, before sending the Notify message for notifying the status of each participant user in the multiparty call conference to the conference subscriber, the method also includes:

When receiving the Notify message that contains the long number sent by the multi-party call conference server, obtain the long number in the Notify message that contains the long number, and determine the long number in the Notify message that contains the long number according to the corresponding relationship between the stored long number and the short number The short number corresponding to the long number.

Correspondingly, on the terminal side, as shown in Figure 2, a message transmission method in a multi-party call conference is also proposed:

21. The UE establishes a multi-party call conference by dialing a short number.

22. When the state of the first participating user in the multi-party calling conference changes, the UE receives a Notify message for notifying the states of the participating users in the multi-party calling conference.

The Notify message includes the status of the first conference participant and the short number of the first conference participant.

Wherein, the Notify message includes the corresponding relationship between the short number and the long number of the first participating user, wherein the long number is a unique identifier assigned by the operator to the first participating user.

Embodiment two

On the basis of the first embodiment above, further, in the technical solution proposed by the second embodiment of the present invention, it is applied to the short number service platform of the intelligent network, and the corresponding relationship between the long number and the short number is added in the Notify message through the short number service platform of the intelligent network To realize the message transmission method in the multi-party call conference, a logical judgment unit is added to the short number service platform of the intelligent network. If the short number is included in the signaling received by the short number service platform of the intelligent network, the short number service platform of the intelligent network That is, add the indicating field of the corresponding relationship between the long number and the short number; if the signaling received by the intelligent network short number service platform is a standard format number, then do not add the indicating field for the corresponding relationship between the long number and the short number. Specifically as shown in Figure 3, the processing process is as follows:

In step 31, the intelligent network short number service platform receives service signaling such as call and short message sent by the UE.

Step 32 , the intelligent network short number service platform judges whether the received service signaling contains a short number, if the judgment result is yes, execute step 33 , otherwise execute step 34 .

In step 33, the intelligent network short number service platform adds an indication field of the corresponding relationship between the long number and the short number in the received service signaling.

In step 34, the intelligent network short number service platform does not add the indication field of the corresponding relationship between the long number and the short number.

The above service signaling is applied when the user subscribes to the conference in the multi-party call conference through the short number, and in the service scenario such as the user executes the call by dialing the short number, all the service signaling (such as: Invite) containing the short number information, in the When the intelligent network short number service platform on the network side, the intelligent network short number service platform adds the long number and short number corresponding fields (number translation) in the Notify message returned by the conference server according to the long number and short number correspondence relationship signed by the user, and Fill in the message body corresponding to the short number and long number. For example: In the Notify message SDP message body, add number translation: 607/1391157607. When the conference initiator receives the Notify message carrying the long and short number corresponding fields (number translation), the initiator judges and refreshes the status of the participants according to the long and short number corresponding fields. As shown in Figure 4, the specific processing flow is as follows:

Assume that the conference initiator is User A, who invites User B and User C to participate in a multi-party call conference, and User A signs a conference subscription message at the same time, User A’s short number is 606, User A’s short number is 607, and User C’s short number is 608 .

Step 41, User A sends a service signaling Invite including short number information.

Wherein, the list 607 (short number of user B) 608 (short number of user C) carried in the SDP message of the service signaling Invite is similar to that below, and will not be repeated here.

Step 42, the intelligent network short number service platform receives the service signaling Invite sent by user A.

Step 43, the intelligent network short number service platform determines that the service signaling Invite contains the short number.

Step 44: The intelligent network short number service platform translates the short number contained in the service signaling Invite into a long number according to the correspondence between the pre-contracted long number and the short number.

Step 45, the short number platform of the intelligent network sends the Invite to the multi-party call conference server.

In the Invite sent by the short number platform of the intelligent network, it contains the list of multi-party call conferences, which includes the translated long numbers of user B (long number is 11111111111) and user C (long number is 22222222222), as well as their respective and short number corresponding relationship.

Step 46, the multi-party call conference server receives the Invite, and allocates multi-party call conference resources.

Step 47, the multi-party call conference server sends 183 session progress to user A through the short number platform of the intelligent network.

Step 48, user A sends a SUBSCRIBE message.

The subscription message requests to subscribe to the status (Conference StateEvent Packet) of each participating user in the multi-party conference call.

The request (Request-URI) field is carried in the SUBSCRIBE message, and the conference subscriber user fills in the user ID in the ConferenceURI field, for example, fills in the Conference URI as UE A,

Step 49, the multi-party call conference server receives the SUBSCRIBE message.

The multi-party call conference server obtains the user identifier as UE A in the Conference URI field of the SUBSCRIBE message.

Step 50, the multi-party call conference server replies a 200 OK message to user A.

Step 51 , the multiparty call conference server sends the status of each participating user to the conference subscriber through a Notify message according to the status of all participating users in the multiparty call conference.

Wherein, in the above step 51, the multi-party call conference server determines that the status of the participating users in the multi-party call conference changes according to the states of all participating users in the multi-party call conference, assuming that user B leaves, the multi-party call conference server Send a Notify message to user A, which contains the long number of user B in the Notify message. When the Notify message passes through the intelligent network short number service platform, the intelligent network short number service platform will Add long and short number corresponding fields (numbertranslation) in the Notify message returned by the multi-party call conference server, and fill in the corresponding message body of the short number and long number. When the conference initiator (user A) receives the Notify message carrying the long and short number corresponding fields (number translation), the initiator judges and refreshes the status of the participants according to the long and short number corresponding fields.

If the conference initiator (user A) uses a long number to page and establish a multi-party call conference, when the Notify message returned by the multi-party call conference server passes through the network-side smart short number platform, the smart network short number platform will not add long and short number correspondence Field, that is, if omitted, there is no corresponding relationship by default. When the initiator of the multi-party call conference (user A) receives the Notify message that does not contain the long and short number corresponding fields (number translation), it defaults to match and refresh the participant status according to the user numbers in the conference list.

Embodiment three

At present, the intelligent network short number service platform in the existing network can only translate the short number sent by the user during the paging process into the corresponding long number according to the intelligent network database according to the short number service activated by the user. In the technical solution proposed in Embodiment 3 of the present invention, the service function of translating long numbers to short numbers is added on the short number service platform of the intelligent network.

In the technical scheme proposed in the third implementation of the present invention, when the user executes the multi-party call conference by dialing a short number, and when the signing conference is scheduled, the multi-party call conference server sends a Notify message containing a long number. When using the service platform, the smart network short number service platform performs reverse translation from long numbers to short numbers, and changes the long numbers of participating users in the Notify message to the short numbers before translation. Specifically, as shown in Figure 5, its specific processing flow is as follows:

Assume that the conference initiator is User A, who invites User B and User C to participate in a multi-party call conference, and User A signs a conference subscription message at the same time, User A’s short number is 606, User A’s short number is 607, and User C’s short number is 608 .

501. User A sends a service signaling Invite including short number information.
