With the full coverage of the 4G and 5G networks, the native audio/video call services of the mobile phone terminal are basically provided by the operator IMS (InternetProtocol Multimedia Subsystem ) network. When the user encounters the condition that the network coverage of a specific operator is not achieved, the operator provides value added services such as short message reminding and the like for the user of the receiving party, and the value added services are used for receiving short message event reminding and voice mail which are not achieved by the early-stage incoming call after the network of the user is restored, so that the user can dial back and refer to the short message event reminding and voice mail.

In order to enable a person skilled in the art to better understand the technical solutions of the present application, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

It should be noted that the terms "first," "second," and the like herein are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the application described herein may be implemented in sequences other than those illustrated or otherwise described herein. The implementations described in the following exemplary examples do not represent all implementations consistent with the application. Rather, they are merely examples of apparatus and methods consistent with aspects of the application as detailed in the accompanying claims.

It should also be understood that the term "and/or" is merely one association relationship describing the associated object, and means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.

As shown in fig. 1, the basic communication audio-video call is based on the intercommunication of the signaling and media related information carried by the proprietary radio channel of the operator. With the full coverage of 4G, 5G (5 th Generation Mobile Communication Technology, fifth generation mobile communication technology) networks, audio and video call services native to mobile terminals such as mobile phones are basically provided by the basic call IMS network of an operator. Under the condition that a user cannot cover a specific operator network, aiming at a receiver user, the operator also provides value-added services such as short message reminding and the like, and is used for receiving short message event reminding and voice mail which are unreachable in the early-stage call after the user IMS network is restored, so that the user can dial back and refer. For the initiator user, the signal recovery is considered, or other VoIP non-basic communication services are used to initiate the required real-time call.

With the rapid development of national APP (Application) products such as WeChat for many years, users have grown up the habit of real-time conversation through OTT VoIP products of non-basic communication types based on the flexible characteristics of network availability and the like. In order to ensure the real-time conversation quality, the basic communication conversation service always maintains a mechanism for realizing intercommunication between the terminal and the operator network based on a special communication channel, including the newly introduced real-time data interaction characteristic of the 5G new conversation.

The 5G message conforms to the RCS (Rich Communication Suite, rich media communication suite) standard, and realizes the rich media upgrading of the short message service. Although basic communication service is located, in order to promote user experience and standard OTT products, a mechanism for bearing service signaling and media streams by using a universal data channel (public wireless data channel access) is supported by preferentially accessing through WiFi (wireless fidelity ) in implementation. And therefore, the terminal access aspect is more flexible than the basic communication call function. Therefore, with the evolution of basic service of operators, calls and messages are mutually integrated, and more possibilities are brought for improving service coverage and experience.

The implementation mode is mainly to adopt video degradation fallback voice, and inform a historical call record mode through terminal built-in voice or near real-time basic information under the condition that an operator network signal (a special wireless channel access mode) is poor or no signal no matter an initiator or a receiver is the basic communication call service. And when the current network environment of the operator of the user does not meet the real-time conversation behavior, degrading the network environment into voice and quasi-real-time notification service with smaller bandwidth requirements. The method specifically comprises the following steps:

1. Under the condition of weak signal, real-time video call falls back

In the process of establishing a video call or calling a user, when an MO (Mobile Origination Call, calling) terminal and an MT (Mobile Termination Call, called) terminal perform RTP (Real-time Transport Protocol ) media stream interaction, if network indexes such as packet loss detection, time delay and the like cannot meet the video call requirement, a negotiation mechanism of video to voice call fallback is triggered. And the voice call is used for going to the bottom, so that the execution of the basic real-time call is ensured.

2. Under the condition of no signal, the call cannot be established, and the reminding is triggered.

As shown in fig. 2, for the scenario that the initiator has no signal, if the mobile phone call fails, the voice notification failure information is directly and locally played. As shown in fig. 3, for the receiver no-signal scenario, the paging failure of the called party is caused, if the user subscribes to the related short message incoming call reminding value-added service, after the user signal is recovered, the history calling event will push the related short message reminding information to the terminal side through the short message center.

In summary, the current call requirements in the weak network environment of the operator can be practically satisfied only by degrading the service mode, especially the voice call, and the user can only make a call again under the condition of re-possessing the network condition by reminding.

Compared with the communication function provided by OTT products, the mobile phone access network has the characteristic of unlimited types, and the communication service can ensure the communication quality through the proprietary network, but the flexibility of service coverage is insufficient. In many cases, users can only actively select OTT products to meet the call demands. The realization of the call function of the OTT product needs to be completed in a closed-loop client and platform system, and the coverage range of the OTT product depends on the coverage range of the client of the OTT product.

In order to solve the above-mentioned problems, the embodiments of the present application provide a method and an apparatus for assisting in providing a real-time call capability, and in particular, relate to a method and an apparatus for implementing a real-time call function with assistance of a 5G message, which can provide a better real-time communication assistance function for an operator-based communication service by upgrading the capabilities of a 5G message platform and a terminal based on the rich media capability of the 5G message, SIP (Session Initiation Protocol ) technology protocol stack base, and 3-item base features independent of the type of access network.

Fig. 4 is a flow chart of a method of assisting in providing real-time telephony capabilities in accordance with one embodiment of the present application. It should be noted that the method for assisting in providing real-time call capability according to the embodiment of the present application may be applied to the 5G message platform according to the embodiment of the present application, where the 5G message platform includes an SBC (Session Border Control, session border controller) network element, a CSCF (CallSession Control Function ) network element, and a CALLAS (CALL ApplicationServer ) network element. As shown in fig. 4, the method of assisting in providing real-time call capability may include the following steps.

In step S101, in response to receiving a call INVITE message (INVITE message) sent by the calling terminal through the WIFI device, the SBC network element sends the call INVITE message to the CALLAS network element through the CSCF network element; the call invitation message includes the telephone number of the calling terminal and the telephone number of the called terminal.

The calling terminal is a 5G message terminal.

And the SBC network element responds to the receiving of the call invitation message sent by the calling terminal through the WIFI equipment, and sends the call invitation message to the CALLAS network element through the CSCF network element.

Aiming at the problem of the initiator with poor coverage of the existing network signals, namely the area where the initiator is located has no base station signals and cannot access the IMS core network through the base station, at the moment, the initiator, namely the calling terminal, can send a call invitation message to a 5G message platform so as to attempt to establish a 5G message call channel, and the real-time call capability is realized.

The IMS core network is used for providing call service, and the terminal is connected with IMS core network equipment through an access network element in the process of call to establish a basic link of call. When the terminal uses technologies such as a Long term evolution Voice bearer (Voice over Long-TermEvolution, voLTE), a new air interface Voice bearer (Voice over New Radio, voNR), a Long term evolution Video bearer (Video over Long-TermEvolution, viLTE), a new air interface Video bearer (Video over New Radio, viNR) and the like to talk, the access network element in the basic link is a base station.

Taking IMS core network equipment as an example, the establishment process of the basic link is described. For example, the calling terminal and the called terminal may establish a basic link for a call between the two terminals using a session initiation protocol (Session Initiation Protocol, SIP), and transmit a call packet through the basic link, so as to implement the call between the two terminals.

The 5G message platform provides basic rich media message service, and the intercommunication standard protocol between the 5G message platform and the terminal adopts an SIP protocol stack consistent with the conversation service. And in the terminal access capability layer, the terminal access capability layer is consistent with OTT products, and the network type is not limited. The user can use the wireless communication terminal in the 5G message terminal as long as the wireless communication terminal has a data network, and the wireless communication terminal can be accessed in a WIFI mode even if the wireless communication terminal is not covered by the wireless signal network of the operator.

The WiFi device includes a WiFi router or a WiFi hotspot device.

The 5G message platform is oriented to interaction of terminals and outsourcing systems and conforms to RCS and related telecommunication technology protocol standards. The functional network element in the 5G message platform can be realized by adopting a standard IMS+AS architecture or an equivalent simplified architecture functional module, and the corresponding streaming media service AS is further introduced into the 5G message platform domain on the basis of the existing standard functional network element because the processing of real-time media stream services such AS communication, even live broadcast and the like is involved, AS the CallAS network element in the embodiment of the application. The 5G message platform and the IMS core network are kept in butt joint through various standardized modes, such as unified interaction with iSBC network elements of the IMS core network for converging all signaling and media streams, so as to realize the intercommunication of audio and video call functions.

In step S102, in response to receiving the call invite message, the CALLAS network element completes the calling logic processing based on the phone number of the calling terminal, and sends the call invite message to the IMS core network through the CSCF network element and the SBC network element based on the phone number of the called terminal, so as to request the IMS core network to send the call invite message to the called terminal to establish a 5G message call path.

In this embodiment, the calling logic process includes: and confirming whether the calling terminal has the operations of calling capability based on the 5G message, ticket generation and the like.

It should be noted that, the terminal needs to register the capability of making a call based on the 5G message with the 5G message platform in advance, and also can establish a 5G message call channel.

As an implementation manner, in response to receiving a registration request message sent by a calling terminal, the SBC network element forwards the registration request message to the CSCF network element; the registration request message comprises 5G message conversation capability indication information, wherein the 5G message conversation capability indication information is used for indicating whether the calling terminal has conversation capability based on the 5G message; in response to receiving the registration request message, the CSCF network element sends a third party function registration request message to the CALLAS network element; the third party function registration request message comprises 5G message call capability indication information; in response to receiving the third party function registration request, the CALLAS network element records whether the calling terminal has the capability of making a call based on the 5G message call capability indication information.

It should also be noted that, the 5G message platform carries the exchange of media message content information through HTTP and MSRP protocols, and mainly meets the requirements of non-real-time rich media services. With the evolution of future rich media services, further support for real-time streaming media processing is necessarily required, so from the aspect of capability support, the 5G message platform is reasonable in consideration of real-time media streaming protocol stack support covering the call class. The 5G messaging service is homologous to the protocol stack of the underlying telephony service, thus maintaining an interworking mechanism of SIP signaling + RTP media. When the WiFi access is performed, the SIP over TLS mode is adopted unchanged. And supporting SRTP protocol for the newly added RTP media stream, and ensuring the transmission security of the media stream under the WiFi access condition. The SIP signaling and SRTP media protocol stack is adopted, so that the terminal side can multiplex the call protocol stack, and real-time communication processing is supported in the 5G message.

Multiplexing 5G message WiFi access capability, adding an encrypted SRTP streaming media interaction mechanism under the existing SIP protocol access protocol, providing a mechanism of audio and video call function, and maximally reducing the adaptation threshold of the terminal.

And further introducing the support of a standardized SRTP streaming media protocol on the conventional standardized SIP protocol stack system of the 5G message, and adding Call AS service corresponding to the Call. Based on the existing 5G message SIP registration and SIP connection, the audio and video call service capability based on WIFI access is realized. Functionally, the method can cover the situation that the identities of the C-terminal user as a calling party and a called party are insufficient in the large network signal, and provides effective auxiliary fallback calling capability for the existing basic calling service of an operator. Under the condition that the impact of function use is not brought to the existing network basic call service, the success rate and the user experience of the call are further improved. The introduction of the call auxiliary fallback mechanism also improves the competitiveness of basic call services.

According to the method for assisting in providing real-time call capability, a call fallback mechanism with 5G message WIFI access capability is added on the basis of the existing carrier basic audio/video call service, a better real-time communication assisting function is provided for carrier basic communication service, call accessibility under extreme conditions such as unreachable communication network is guaranteed, and call success rate and user experience are further improved.

The above embodiments are directed to the problem of the initiator of the poor coverage of the existing network signal, and the following describes the problem of the receiver of the poor coverage of the existing network signal based on the above embodiments.

Fig. 5 is a flow chart of a method of assisting in providing real-time telephony capabilities in accordance with another embodiment of the present application. As shown in fig. 5, the method of assisting in providing real-time call capability may include the following steps.

In response to receiving the call invite message sent by the IMS core network, the CSCF network element sends the call invite message to the CALLAS network element in step S201.

Aiming at the problem of the receiver with poor coverage of the existing network signals, the IMS core network triggers a call fallback attempt to the 5G message platform, and the IMS core network sends a call invitation message to the CSCF network element of the 5G message platform.

In step S202, in response to receiving the call invite message, the CALLAS network element completes the calling logic processing based on the phone number of the calling terminal, and sends the call invite message to the called terminal through the CSCF network element, the SBC network element, and the WIFI device based on the phone number of the called terminal, so as to establish a 5G message call channel.

It should be noted that, in the embodiment of the present application, the partial implementation process of the step S202 may be referred to the description of the implementation process of the step S102, which is not repeated herein.

According to the method for assisting in providing the real-time communication capability, aiming at the problem of poor signal coverage of a receiver, a call fallback mechanism with the 5G message WIFI access capability is added on the basis of the existing carrier basic audio/video call service, a better real-time communication assisting function is provided for carrier basic communication service, call accessibility under extreme conditions such as unreachable communication network is ensured, and the success rate and user experience of call are further improved.

On the basis of any of the above embodiments, a terminal-side implementation of the initiator signal coverage problem and the receiver signal coverage problem will be described below, respectively.

Fig. 6 is a flow chart of a method of assisting in providing real-time telephony capabilities in accordance with yet another embodiment of the present application. As shown in fig. 6, the method of assisting in providing real-time call capability may include the following steps.

In step S301, no base station signal in the current area is detected, and a real-time call in the 5G message mode is triggered.

Aiming at the problem of the initiator with poor coverage of the current network signal, the calling terminal can not carry out call connection with the called terminal under the condition of poor quality detection of the RTP media network of the calling terminal, and the calling terminal triggers the real-time call of the 5G message mode.

In step S302, in response to triggering the real-time call in the 5G message mode, a call invite message is sent to the 5G message platform through the WIFI device to request the 5G message platform to send the call invite message to the IMS core network, so as to establish a 5G message call channel.

And the calling terminal responds to the real-time call triggering the 5G message mode, and sends a call invitation message to the 5G message platform through the WIFI equipment so as to request the 5G message platform to send the call invitation message to the IMS core network, so that a 5G message call channel is established.

As one implementation, a registration request message is sent to a 5G message platform; the registration request message includes 5G message session capability indication information for indicating whether the terminal has a capability of making a session based on the 5G message.

It will be appreciated that the terminal needs to register in advance with the 5G message platform that it has the capability to make a call based on the 5G message, and may also be able to successfully establish the 5G message call path.

As an implementation manner, under the condition that the 5G message call channel is successfully established, the message interaction interfaces of the first terminal and the called terminal both generate and display a call message record, and the call message record includes a re-dialing button.

It can be understood that, the terminal side adds a message record association adaptation mechanism, and whether the user successfully initiates the fallback call or receives the fallback call through the 5G message channel, a call record message is automatically generated in the corresponding message interaction interface. To enhance the use experience, the call log message may employ a card message with the addition of a "redial" or "redial" button. For example, as shown in fig. 7, when the user clicks the button, the format of pulling up the call interface and automatically dialing the number is defined by the RCS standard suggestion operation link or deep link mechanism, such as: the link points to "call: +10000000000", jump to the corresponding call interface, and dial by the user selection.

After triggering a call fallback function under the WiFi access of the 5G message, automatically generating a call message record (call record card message) corresponding to the calling and called session interfaces of the 5G message, and providing a function entry for the user to dial again. The history information mechanism of the fall back record is presented in the form of a 5G message.

Aiming at the problem of the initiator with poor signal coverage of the existing network, the terminal side is controlled by upgrading, as shown in fig. 8, under the condition that the large network has no signal or needs to fall back and has WIFI access, the capability of preferentially attempting peer-to-peer real-time conversation through a 5G message conversation channel is increased. The existing fall-back or alert mechanism can be used as a spam flow in the event of a final failure. Once a call is initiated through the 5G message, in a corresponding message interface with the called number, an associated call message record is generated by the terminal. Wherein the large network refers to the basic network of the operator, and in this embodiment refers to the IMS network.

The call interworking mechanism after adding the 5G message call is exemplified as follows:

for the main line flow scene of initiating flow and receiving from the 5G message terminal when the call is initiated, taking VoLTE call as an example, the realization mechanism of providing auxiliary fallback capability for the call service based on the representative 5G message (other network MO and MT call scenes related to 5G VoNR, 3G and the like are similar, and only the signaling flow has a certain difference according to standard definition). The related flow mechanism is suitable for voice and video call, and the interaction mechanism corresponding to voice and video complies with the IMS prior art standard.

1) 5G message assisted talk fallback priority

The call function based on the 5G message WIFI access capability provides a priority implementation mechanism of a fallback mechanism for the operator base CT audio/video call, compared with the existing network, as follows:

< 1 > active network user initiates a call: CT video call establishment failure- & gt automatic fallback CT voice call establishment failure- & gt calling prompt call failure, if the called party is not reachable, further pushing the called short message call prompt is provided.

< 2 > the present application example user initiated call: including the following 2 modes. The 2 nd mode mainly considers the influence of continuous delay under the condition of multiple fall-back superposition, and calls the 5G message to assist in calling the bottom of the call in case of failure of the CT call in the existing network:

in the 1 st mode, the CT video call establishment failure is more than the automatic fallback 5G message video call establishment failure is more than the automatic fallback CT voice call establishment failure is more than the automatic fallback 5G message voice call establishment failure is more than the calling prompt call failure, and if the called party is not available, the call prompt is provided for further pushing the called short message.

In the 2 nd mode, the CT video call establishment failure is more than the automatic fallback CT voice call establishment failure is more than the automatic fallback 5G message video call establishment failure is more than the automatic fallback 5G message voice call establishment failure is more than the calling prompt call failure, and if the called party is not available, the call prompt is provided for further pushing the called short message.

By implementing the embodiment, a mechanism for enabling the sender side MO flow 5G message WiFi call fallback is provided for the situation that the calling user has no communication signal. The problem that the call is unreachable under the condition that the communication network is not available or weak communication network exists in the call initiation scene is solved, and the success rate of basic communication service call is improved.

Fig. 9 is a flow chart of a method of assisting in providing real-time telephony capabilities in accordance with yet another embodiment of the present application. As shown in fig. 9, the method of assisting in providing real-time call capability may include the following steps.

In step S401, in the case that the call connection to the called terminal fails to be established based on the IMS core network, the IMS core network is requested to send a call invite message to the 5G message platform, so as to request the 5G message platform to send the call invite message to the called terminal through the WIFI device, so as to establish a 5G message call channel.

For the problem of the receiver covered by the existing network signal, as shown in fig. 10, the upgrade control of the side of the operator platform (5G message platform) increases the peer-to-peer fallback through the real-time calling capability of the 5G message when the receiver (called terminal) is not reachable. The existing fall-back or alert mechanism serves as a bottom-of-the-way flow in the event of a final failure. Once the receiver 5G message channel layer is reachable, in the receiver message interface, the terminal generates an associated call message record.

By implementing the embodiment, a mechanism for receiving party platform side MT flow 5G message WiFi call fallback is provided for the situation that the called party does not have communication signals respectively. The problem that the call is unreachable under the condition that the call receiving scene has no communication network or weak communication network is solved, and the success rate of basic communication service call is improved.

In example 1, taking VoLTE call as an example, a user initiates VoLTE call using a first terminal (5G message terminal), but when no call signal is encountered in the current area but WiFi connection is present, the fallback of the call is achieved through the 5G message channel. As shown in fig. 11, the following operations are included:

the precondition for realizing the fallback of the call through the 5G message channel is that the first terminal registers with the 5G message platform in advance and has the capability of carrying out the call based on the 5G message.

Wherein the registration process includes the following operations:

steps <1> - <3>, the first terminal sending a registration request (Register message) when performing SIP (Session initialization Protocol, session initiation protocol) registration, wherein the Contact field in the Register message comprises a 5G message session capability indication information bit, and the content of the 5G message session capability indication information bit indicates that the first terminal has the capability to make a session based on the 5G message. The 5G message session capability indication information is used to indicate whether the terminal to which the telephone number belongs has a capability of making a session based on a 5G message. The 5G message platform determines whether the terminal has the capability of making a call based on the 5G message by identifying 5G message call capability indication information of the terminal.

The 5G message conversation capability indication information is used for identifying whether the terminal has the conversation capability based on the 5G message or not by adding a Contact field of the Register message with a 5G message conversation capability indication information bit. For example, a content of 1 in the 5G message conversation capability indication information bit indicates that the corresponding terminal has the capability of making a conversation based on the 5G message, and a content of 0 in the 5G message conversation capability indication information bit indicates that the corresponding terminal does not have the capability of making a conversation based on the 5G message.

And step <4>, according to a third party function registration request submitted to the callAS network element by a peer-to-peer module of the CSCF network element of the 5G message platform, the callAS network element records whether the terminal to which the corresponding telephone number belongs has the capability of carrying out conversation based on the 5G message.

The process of realizing the fallback of the call through the 5G message channel comprises the following steps:

and step <5>, the user initiates a call on the call interface through the first terminal, and the first terminal detects that no signal exists in the current area, and automatically triggers the call-back flow to be initiated through the 5G message channel. I.e. sending a call invite message to the SBC network element of the 5G message platform, the call invite message carrying media negotiation SDP information of the first terminal. Response messages such as 183/200/ACK received by subsequent association are processed according to the conversation SIP standard flow, and are not described repeatedly.

Step < 6> - < 7 >, the SBC network element further forwards the call invite message to the CSCF network element and the CallAS network element, respectively.

And steps <8> - <9>, the CallAS network element completes calling MO logic processing of calling numbers including calling authority, ticket generation and the like, and triggers a call flow unless the called number is directed to the VoLTE domain according to the routing of the called number. And finally, the CSCF network element of the 5G message platform sends the call invitation message to an iSBC gateway of a called number end VoLTE core network (VoLTE network IMS domain).

And steps <10> - <13>, the VoLTE core network receives the call invitation message and completes the paging of the called user.

And step (14) - (16), the call signaling flow interaction between the calling end and the called end is completed, after the media negotiation is successful, the SBC network element of the 5G message platform is transferred through the iSBC gateway of the VoLTE core network, and SRTP media flow interaction is carried out with the SBC network element of the VoLTE core network, so that the calling and called calls are established.

Step < 17 >, the calling and called calls are successfully established, the associated call record card message is automatically generated and presented in the message session interface of the calling party and the message session interface of the called party, and the call record card message carries a deep redial button as shown in fig. 4.

In example 2, taking VoLTE call as an example, a user initiates a call normally in a call interface of a first terminal, and when a called terminal has no signal but has WIFI connection, the call falls back through a 5G message channel, so as to achieve the accessibility of the current call. As shown in fig. 12, the specific process includes the following operations:

Step < 1 > - < 2 >, and the VoLTE network side fails to page the called party according to the current network flow. The AS network element of the VoLTE core network triggers a call fallback attempt further to the 5G message domain. And sending a call invitation message through CSCF network elements and the iSBC gateway of the VoLTE core network in sequence, wherein the call invitation message carries media negotiation information of a calling terminal.

The iSBC gateway of the VoLTE core network forwards the call invitation message to the CSCF network element of the 5G message platform, the CSCF network element pushes the call invitation message to the CallAS network element of the 5G message platform to carry out call authority, call ticket generation and other called logic processing, and the call AS network element further pushes the call invitation message to the called terminal side through the CSCF network element and the SBC network element and through the SIP connection of the 5G message. And completing the interaction of the fallback signaling flow.

Step < 8 > - < 9 >, finishing the signaling flow processing, after the media negotiation, finishing SRTP media flow interaction by the SBC network element of the VoLTE core network and the SBC network element corresponding to the 5G message platform through the iSBC gateway of the VoLTE core network.

Step < 10 >, the calling and called call is successfully established, and the related call record card message is automatically generated and presented on the message session page of the calling and called call, wherein the call record card message carries a deep re-dialing button.
