Detailed Description

The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments that can be derived from the disclosure by one of ordinary skill in the art based on the embodiments in the disclosure are intended to be within the scope of the disclosure.

In order to more clearly describe the calling method provided by the embodiment of the present disclosure, a possible application scenario of the calling method provided by the embodiment of the present disclosure will be exemplarily described below, it should be understood that the following example is only one possible application scenario of the calling method provided by the embodiment of the present disclosure, and in other possible embodiments, the calling method provided by the embodiment of the present disclosure may also be applied to other possible application scenarios, and the following example does not limit this.

With the development of communication technology, a terminal with a DC function can use application services with other DC functions in addition to call in a call process, according to actual needs of users participating in the call, for example, application services such as content sharing, screen sharing, simultaneous interpretation and the like are performed between call terminals. Based on this, the present disclosure provides a calling method to reduce resource waste, the method is applied to a multimedia telephony application server MMTEL AS in a calling system, the calling system further includes a data channel DC service platform, AS shown in fig. 1, the method includes:

s101, responding to a preset access code sent by a first user end in a conversation process with a second user end, and generating a first service request containing the preset access code, a first identifier and a second identifier.

And S102, sending the first service request to a DC service platform, so that the DC service platform responds to a preset access code, a first identifier and the second identifier, establishes data channels with a first user end and a second user end respectively, and pushes an application list to the first user end and the second user end respectively through the data channels.

In the embodiment, the MMTEL AS is applied to a multimedia telephony application server MMTEL AS in a call system, because the preset access code is an access code for requesting a data channel service, when the MMTEL AS receives the preset access code sent by a first user during a call between the first user and a second user, it can be determined that the first user needs to use the data channel service during the call between the first user and the second user and view an application list corresponding to the service, and therefore, the MMTEL AS generates a first service request including the preset access code and a first identifier of the first user and a second identifier of the second user in response to the preset access code and sends the first service request to a DC service platform, so that the DC service platform confirms that the first user needs to use the data channel service according to the preset access code in the first service request, and determines that the data channel service needs to be used simultaneously according to the identifier of the first user and the identifier of the second user in the first service request And the first user side and the second user side are served, so that a data channel is established for the first user side and the second user side, and an application list is pushed. Whether the user side needs to use the data channel service is judged by receiving the preset access code, and the data channel service is provided for the user side under the condition that the user side needs to use the data channel service is realized by the generated first service request, so that the resource waste is reduced.

In S101, the first identifier is an identifier of a first user, the second identifier is an identifier of a second user, and the preset access code is an access code for requesting a data channel service. The first user terminal and the second user terminal may be different types of terminal devices according to different application scenarios, the first user terminal and the second user terminal should have at least a call function and a DC function, and the exemplary first user terminal and the second user terminal may be any one of the following devices: cell-phone, flat board, notebook, smart television, intelligent wrist-watch. The first identifier and the second identifier may be different types of identifiers according to different types of the first user side and the second user side, and for example, the first identifier and the second identifier may be phone numbers or other device codes capable of uniquely identifying devices.

In the process of using the first user to make a call, if a data channel service such as content sharing, screen sharing, simultaneous interpretation and the like is required, a preset access code may be input on the first user, where the preset access code is an access code known by the first user in advance and used for requesting the data channel service, and may be a number, a letter, or a combination of a number and a letter, which is not limited in the present disclosure. It can be understood that, before the MMTEL AS receives the preset access code, the MMTEL AS has already completed the call setup of the first user side and the second user side, and therefore, the identifiers corresponding to the two user sides are recorded, so that, when the MMTEL AS responds to the preset access code sent by the first user side, the MMTEL AS can determine the first identifier and the second identifier, and determine that the first user side and the second user side need to use the data channel service, thereby generating the first service request including the preset access code, the first identifier and the second identifier. The preset access code may be input through a touch screen or a voice, which is not limited in this disclosure. .

In S102, the MMTEL AS sends the first service request to the DC service platform, so that the DC service platform determines, according to the first identifier and the second identifier in the first service request, the first user end and the second user end that are in communication, and determines, according to the preset access code, that the first user end and the second user end need to use the data channel service, thereby establishing data channels with the first user end and the second user end, respectively, and pushing the application list, so that the first user end and the second user end use the data channel service.

As mentioned above, if the first ue sends the default access code during the call, it means that the first ue wishes to use the data channel service, and needs the DC service platform to establish a data channel with the first ue and push the application list, can judge the first user terminal as the target user terminal of the data channel service according to the behavior of the first user terminal actively sending the preset access code, and then the first user terminal can need to use the data channel service frequently, however, if the preset access code needs to be sent every time the first user terminal uses the data channel service, it may cause bad experience to the user and may also reduce the call efficiency of the system, based on which, the present disclosure also provides a call method, which is applied to a multimedia telephony application server MMTEL AS in a call system, the call system further includes a data channel DC service platform, AS shown in fig. 2, the method includes:

s201, responding to a preset access code sent by a first user end in a conversation process with a second user end, and determining the first user end as a signing user end.

And S202, responding to the third user side and the fourth user side which are determined to be the signing user side to carry out communication, and generating a second service request comprising a preset access code, a third identifier and a fourth identifier.

S203, sending the second service request to the DC service platform, so that the DC service platform establishes data channels with the subscriber side and the fourth user side respectively in response to the preset access code, the third identifier, and the fourth identifier, and pushes the application list to the subscriber side and the fourth user side respectively through the data channels.

In S201, as described above, if the first user sends the preset access code during the communication with the second user, it may be determined that the first user is the target user of the data channel service, and therefore, the first user may be signed with the corresponding data channel service, so that the first user is used as the signed user. It can be understood that the subscription mode may be to set a preset flag for the first user end, or to add a preset field to the first identifier corresponding to the first user end, which is not limited in the present disclosure, and no matter what type of subscription is performed, the MMTEL AS of the call system may identify the first user end AS the subscription user end and determine the preset access code input by the first user end in the previous call process in the process of making a call again by the subsequent first user end. It is to be understood that the first and second of the first and second ues in the present disclosure are only for convenience of description, and do not refer to specific two ues, so that a ue is determined as a subscriber ue whenever it sends a predetermined access code during passing through with other ues.

In S202, the third identifier is an identifier of a third user, and the fourth identifier is an identifier of a fourth user. Similarly, the third ue and the fourth ue in the present disclosure do not refer to two specific ues, and since the first ue has been determined as a subscribed ue in the aforementioned S201, in one possible embodiment, the third ue and the aforementioned first ue may be the same ue, and in another possible embodiment, the third ue and the aforementioned first ue may also be different ues.

Because the third user side is already a signed user side, it is indicated that the third user side has sent the preset access code in the process of passing through with other user sides before, it can be seen that the third user side is a target user side of the data channel service, that is, the third user side probably needs to use the data channel service in the process of carrying out a call, therefore, on the basis that the third user side is already a signed user side, the MMTEL AS can identify the signed user side in the process of the call of the third user side, and confirms that the third user side needs to use the data channel service with the fourth user side in the process of the call with the third user side according to the corresponding signing mark, and obtains the preset access code input by the third user side in the previous call process, thereby generating a second service request containing the preset access code, the third mark and the fourth mark. It can be understood that the second service request is similar to the first service request, and before the MMTEL AS determines whether the third user terminal or the fourth user terminal is the subscriber terminal, the MMTEL AS has already completed the call setup of the third user terminal and the fourth user terminal, and therefore records the identifiers corresponding to the two user terminals, so that when the MMTEL AS responds to the call between the third user terminal and the fourth user terminal, which are the subscriber terminals, the MMTEL AS can determine the third identifier and the fourth identifier, and determine that the third user terminal and the fourth user terminal need to use the data channel service, and determine the preset access code input by the third user terminal in the previous call process according to the subscription identifier of the third user terminal, thereby generating the first service request including the preset access code, the first identifier and the second identifier. In this disclosure, the third user end and the fourth user end are both user ends with DC function, and the third identifier and the fourth identifier may be phone numbers corresponding to the third user end and the fourth user end, or other codes, which is not limited in this disclosure.

In S203, the steps are similar to S102, except that the service request and the client are different, for a specific request, reference is made to the description of S102, and details are not repeated here.

By selecting the embodiment, the target user side which often needs to use the data channel service can be determined and marked AS the signing user side, so that the MMTEL AS can identify the user side (namely the signing user side) which needs to use the data channel service, the DC service platform can efficiently establish the data channel for the user side and push the application list through the second service request, the user side which needs to often use the data channel service is prevented from repeatedly inputting the preset access code during each call, and the call efficiency is improved while the user experience is improved.

In the process of the user terminal carrying out communication through the calling system, various messages sent by the user terminal, such AS a communication request, a service request or a preset access code, are not directly sent to the MMTEL AS in the calling system from the user terminal, but other units in the calling system are required to carry out message transfer, so that the MMTEL AS receives the messages sent by the user terminal. Based on this, in some embodiments, the call system further comprises: a proxy call session function P-CSCF element and a serving proxy call session function S-CSCF element.

The P-CSCF is used for receiving a preset access code sent by the first user end in the process of communicating with the second user end and sending the preset access code to the S-CSCF.

Specifically, the CSCF Call Session Control Function (Call Session Control Function) is mainly responsible for message Control in the Multimedia Call callback process, and manages user authentication of an IMS (IP Multimedia Subsystem) network, service quality of an IMS bearer plane, Control of a Session Initiation Protocol (SIP) Session in cooperation with other network entities, service negotiation, resource allocation, and the like. It is mainly divided into P-CSCF (proxy CSCF), interrogating CSCF (I-CSCF), S-CSCF (serving CSCF) and E-CSCF (emergency CSCF).

The P-CSCF is the first entity contacted by the user terminal in the call system, and can maintain the security and integrity of messages between the user terminal and the P-CSCF, and forward messages received from the user terminal, such as the default access code, to the S-CSCF completely and safely.

The S-CSCF can process the user side message forwarded by the P-CSCF, forward the user side message to the server, forward the system message to the user side, trigger the MMTEL AS according to the service signing condition of the user, and interact with the service platform to provide the multimedia service for the user side.

By adopting the embodiment, the MMTEL AS can safely and completely receive the message of the user side and further provide corresponding service for the user side, thereby improving the calling efficiency of the user side.

In some embodiments, if the MMTEL AS of the call system needs to be directly sent to the DC service platform, an interface needs to be added, so that message transmission is performed with the DC service platform through the added interface, for example, a first service request or a second service request is sent, so that the DC service platform establishes a data channel for a corresponding user side according to the service request and pushes an application list.

However, if the above-mentioned manner is used to implement the message transmission between the MMTEL AS and the DC service platform, a dedicated interface for communicating with the DC service platform needs to be added to the MMTEL AS, which increases the call cost, and based on this, the present disclosure also provides a call method, and the call system further includes: a serving proxy call session function, S-CSCF, element, the method, as shown in fig. 3, comprises:

s301, responding to a preset access code sent by a first user end in a conversation process with a second user end, generating a call signaling containing the preset access code, a first identifier and a second identifier as a first service request.

And S302, sending the first service request to an S-CSCF, so that the S-CSCF forwards the first service request to a DC service platform, so that the DC service platform responds to a preset access code, a first identifier and the second identifier, establishes data channels with a first user terminal and a second user terminal respectively, and pushes an application list to the first user terminal and the second user terminal respectively through the data channels.

In S301, the first user end, the second user end, the preset access code, the first identifier, and the second identifier are similar to S101, which is not described again, and the call signaling is generated and will be described as the first service request part.

Call signaling is call control commands in a communication system, and is control signals required to ensure normal communication in order to operate the entire system in order in addition to transmitting user information in a wireless communication system. And the MMTEL AS generates a call signaling containing a preset access code, a first identifier and a second identifier, and uses the call signaling AS a first service request, so that a unit which subsequently receives the call signaling can orderly and efficiently control and process an object to be processed according to the signaling content according to the call signaling.

In S302, this step is similar to S102, except that in S302, the first service request is sent to the S-CSCF, so that the S-CSCF forwards the first service to the DC service platform, and similar parts are not described again, and different parts will be explained below.

The calling system further includes an S-CSCF, and AS mentioned above, the S-CSCF may interact with the service platform to provide the multimedia service for the user terminal, and it is visible that the S-CSCF may interact with the DC service platform without passing through an interface, so the MMTEL AS directly forwards the call signaling (the first service request) to the S-CSCF, and may enable the S-CSCF to forward the call signaling to the DC service platform, so that the DC service platform respectively establishes a data channel and pushes the application list according to the content of the call signaling for the first user terminal and the second user terminal.

By adopting the embodiment, the control message is forwarded to the DC service platform by the S-CSCF in a call signaling mode, so that the DC service platform respectively establishes a data channel and pushes an application list according to the content of the call signaling by the first user end and the second user end, the establishment of a newly added interface is avoided, and the call cost is reduced.

It will be appreciated that the call signaling needs to have its uniform format so that the subsequently received elements of the call signaling can identify the content of the call signaling and process it accordingly. Based on this, in some embodiments, the generation process of the call signaling may be: and generating a call signaling with the calling number as the first identifier and the called number as the preset access code and the second identifier.

The method comprises the steps that a first user end corresponding to a first identifier sends a preset access code to actively request data channel service, so that the first identifier is used as a calling number, a second identifier corresponding to a second user end communicated with the first user end and the preset access code sent by the first user end are used as called numbers, and a calling signaling is generated according to the format, so that when a DC service platform receives the calling signaling (a first service request), the DC service platform can determine that the user end needs to use the data channel service according to the preset access code, and then determine that the specific first user end and the specific second user end need to use the data channel service according to the first identifier and the second identifier.

By selecting the embodiment, the generation mode and format of the call signaling are determined, so that after the subsequent MMTEL AS sends the call signaling (the first service request) to the DC service platform, the DC service platform can efficiently execute the signaling content of the call signaling, and the call efficiency of the user side is improved.

It will be appreciated that there are many types of call signaling, and as an example, the call signaling of the present disclosure may be INVITE call signaling.

Since the DC service platform in the calling system is actually used for establishing the data channel and pushing the application list to the user side, the present disclosure also provides a calling method for the MMTEL AS in the calling system, which is applied to the DC service platform in the calling system, and the calling system further includes the MMTEL AS, the method includes:

responding to a first service request received in a process of a conversation between a first user end and a second user end, respectively establishing data channels with the first user end and the second user end according to a preset access code, a first identifier and a second identifier contained in the first service request, and respectively pushing an application list to the first user end and the second user end through the data channels.

The preset access code is used for requesting data channel service, the first identifier is an identifier of a first user terminal, the second identifier is an identifier of a second user terminal, and the first service request is a service request generated by the MMTEL AS in response to the preset access code sent by the first user terminal in the process of communicating with the second user terminal.

Specifically, AS described above, when receiving the preset access code sent by the first user equipment and the second user equipment during the call, the MMTEL AS generates the first service request including the preset access code, the first identifier, and the second identifier, and sends the first service request to the DC service platform. And after receiving the first service request, the DC service platform may determine that a user side needs to use a data channel service according to a preset access code included in the first service request, and determine that the first user side and the second user side specifically need to use the data service according to a first identifier and a second identifier included in the first service request, thereby, in response to the first service request, establishing a data channel with the first user side and the second user side, and pushing an application list to the first user side and the second user side through the data channel, respectively.

With the embodiment, the DC service platform determines whether the user side needs to use the data channel service through the first service request sent by the MMTEL AS, and determines which user sides need to use the data channel service, thereby realizing selective establishment of a data channel and pushing of an application list for the user side that needs to use the data channel service, and avoiding resource waste.

In some embodiments, if the MMTEL AS does not use the newly added interface to perform message transmission with the DC service platform, it needs to forward the message through other units of the calling system, based on which, the present disclosure also provides a calling method applied to the data channel DC service platform in the calling system, the calling system also includes a multimedia telephony application server MMTEL AS, the method includes:

in response to receiving a first service request forwarded by an S-CSCF in the process of a call between a first user terminal and a second user terminal, respectively establishing data channels with the first user terminal and the second user terminal according to a preset access code, a first identifier and a second identifier contained in the first service request, and respectively pushing an application list to the first user terminal and the second user terminal through the data channels.

The preset access code is used for requesting data channel service, the first identifier is an identifier of a first user terminal, the second identifier is an identifier of a second user terminal, and the first service request is a service request generated by the MMTEL AS in response to the preset access code sent by the first user terminal in the process of communicating with the second user terminal. And the S-CSCF forwards the first service request to the DC service platform when receiving the first service request sent by the MMTEL AS.

AS described above, the S-CSCF may interact with the service platform to provide the multimedia service for the user terminal, and it is apparent that the S-CSCF may interact with the DC service platform without passing through an interface, so the MMTEL AS directly forwards the first service request to the S-CSCF, the S-CSCF may forward the first service request to the DC service platform after receiving the first service request sent by the MMTEL AS, and the DC service platform may establish a data channel and push an application list for the first user terminal and the second user terminal, respectively, according to a preset access code of the first service request.

By selecting the embodiment, the first service request sent by the MMTEL AS is forwarded to the DC service platform through the S-CSCF, so that the establishment of a newly-added interface when the MMTEL AS and the DC service platform directly transmit messages is avoided, and the call cost is reduced.

As described above, since the S-CSCF can not only process the ue message forwarded by the P-CSCF, but also forward the ue message to the server, when the DC service platform receives the first service request and determines that it is necessary to establish a data channel for the first ue and the second ue respectively in response to the first service request and push the application list, a response reply is performed, and the reply needs to be forwarded to the first ue through the S-CSCF. As an embodiment, if the S-CSCF forwards the call signaling as the first service request to the DC service platform, and the call signaling is INVITE call information, the DC service platform sends CANCEL to the S-CSCF, so that the S-CSCF forwards the CANCEL to the first user end, so as to complete a message response for the first user end requesting data channel service through a preset access code.

As an embodiment, the DC service platform is established by INVITE call signaling when establishing data channels for the first and second user terminals, respectively. The embodiment can improve the data channel establishing speed, thereby improving the calling efficiency.
