Description

Service bearer method, communication terminal, control network element S-CSCF and system

Technical field

The present invention relates to an IP Multimedia Subsystem (IMS), and more particularly to a service bearer method, a communication terminal, a control network element S-CSCF, and a system.

Background technique

Nowadays, with the rapid development of communication technology, IP technology and Internet applications across the link layer transmission medium are widely used. A single voice communication method has developed into a new multimedia communication method, which has more and more satisfied the demand for communication development.

As an IP multimedia subsystem defined by the 3GPP R5 phase, IMS (IP Multimedia Subsystem) is a new form of multimedia service. It uses the packet domain (PS) as its bearer channel for upper layer control signaling and media transmission, and introduces the session initialization protocol. As a service control protocol, SIP (Session Initiation Protocol) uses SIP to be simple, easy to expand, and easy to combine media. It separates service control from bearer control to provide rich multimedia services. It can meet the needs of current terminal customers. The need for diverse multimedia services. IMS has become the core network standard architecture in the all-IP era because it supports multiple access and rich multimedia services.

VoLTE (Voice over LTE) is an IMS-based voice service. As an IP data transmission technology, it does not require a 2G/3G network. All services are carried on a 4G network. It is the ultimate voice solution of LTE (Long Term Evolution). It can be implemented completely by using the PS domain. The access network is carried over the PS packet domain. The session control and service data transmission are implemented based on IP. The data and voice services can be unified under the same network, which means that the operator can VoLTE provides a higher level of control and management, mobile broadband voice applications will become mainstream, and the traditional CS domain will be gradually replaced. Also based on IP transmission voice, VoWiFi (Voice over WiFi) can use WiFi as an access network, and finally access to the IMS network to complete the voice bearer on the IP. It is an IP voice service that the operator can control and manage. The VoWIFI in the communication field is a function that can be built in the communication terminal, and can directly enter the core network of the operator to realize interworking with the cellular network. In the 3GPP specification, WIFI access is considered as a non-3GPP wireless access. Type, then there are two main ways to implement VoWIFI, that is, voice data is regarded as trusted access through the WIFI access operator core network. And untrusted access, wherein the trusted access mode is completed under the operator's WIFI network, and the user terminal does not need to establish an IPSec tunnel with the network, but can directly access the mobile through the PDN GW (Packet Data Gateway). The network, the untrusted access, needs to access the core network through the ePDG, and the IPSec tunnel between the user terminal and the eDPG carries data. Although the quality of WIFI directly affects the quality of VoWIFI calls, the coverage of WiFi hotspots and signal quality are ideal in indoor and large shopping malls. VoWIFI allows users to obtain lower voice rates and can make up for The 4G network outdoor base station does not cover enough indoors to make the user receive poor signal. Therefore, VoWiFi is more popular in indoor and large shopping malls and other similar scenarios.

At present, domestic operators have begun to deploy VoLTE networks. About VoWIFI, T-Mobile USA first launched the VoWIFI service based on ePDG architecture in 2014. It is believed that the deployment of VoWiFi will be in the near future with the development of communication technologies. It should also be gradually implemented, so that the terminal will inevitably have a state in which VoLTE and VoWiFi are simultaneously resident. However, for a single service, the quality of service Qos that can be provided through a VoLTE or VoWiFi bearer is limited. If a single service is used to share a bearer through a VoLTE or VoWiFi access network, if the VoLTE or VoWiFi access network cannot satisfy the service. Demand, then will not be able to provide better QoS, reducing the user experience. For example, when a current user needs to make a multi-party video call, VoLTE or VoWiFi needs to reserve multiple audio streams and video stream resources. If a single VoLTE or VoWiFi cannot meet the service requirements, sufficient audio stream or video stream cannot be reserved. Resources will not provide better QoS to carry multi-party video calls, thus reducing the user experience.

detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is an embodiment of the invention, but not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of the present invention.

The terms "first", "second", "third", "fourth", etc. (if present) in the specification and claims of the present invention and the above figures are used to distinguish similar objects without having to use To describe a specific order or order. It is to be understood that the data so used may be interchanged where appropriate so that the embodiments described herein can be implemented in a sequence other than what is illustrated or described herein. In addition, the terms "comprises" and "comprises" and "the" and "the" are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or device that comprises a series of steps or units is not necessarily limited to Those steps or units may include other steps or units not explicitly listed or inherent to such processes, methods, products or devices.

In the embodiment of the present invention, it is assumed that there is a first access network and a second access network, and the first access network and the second access network may respectively share the bearer for the communication terminal based on the IP-based communication network, if the first access If the network is VoLTE, the second access network is VoWIFI, and the first access network is VoWIFI, and the second access network is VoLTE.

At present, with the gradual maturity of the VoLTE service, and more and more user terminals support the wireless fidelity WIFI function, the operator can realize the LTE voice call service and the WIFI voice call service by using the IMS. Specifically, the user of the communication terminal holding the above function can provide the VoLTE voice call service to the user through the LTE network, and can also provide the VoWIFI voice call service to the user through the WIFI.

In the existing solution, different access networks respectively provide service bearers for communication terminals, that is, service bearers between different access networks are independent of each other, as shown in FIG. 1 , assuming that users need to perform multi-party video calls, Then, the communication terminal that initiates the multi-party video call needs to transmit and transmit the multi-channel media resource information. If the service needs to carry 6 channels of audio media and 6 channels of video media, the communication terminal can connect to the IMS network through the eNodeB based on VoLTE to implement VoLTE provision 6 The bearer of the audio media and the 6-channel video media, or in the wireless local area network, the communication terminal can connect to the IMS network through the AP based on VoWIFI, and realize the carrying of 6 channels of audio media and 6 channels of video media by VoLTE. However, for a single service, the QoS that can be provided through the VoLTE or VoWiFi bearer is limited, especially for a service that transmits more media content, such as the multi-party video call described above, which may require multiple reservations for VoLTE or VoWiFi. For the resources of the audio stream and the video stream, if the VoLTE or VoWiFi cannot reserve sufficient resources, the service bearer cannot be completed, which may cause the service connection to fail.

In the embodiment of the present invention, based on the state in which the communication terminal VoLTE and the VoWIFI are simultaneously camped, the first access network is VoLTE, and the second access network is VoWIFI as an example, when a single mobile bearer network (VoLTE) has limited bandwidth. If the quality of service provided cannot meet the service requirements, VoWiFi can be used to provide the bearer of some services. As shown in Figure 1, the communication terminal can connect the 3 channels of audio and 3 channels of video to VoLTE through the eNodeB to connect to the IMS network. The 3 channels of audio and the 3 channels of video can be connected to the IMS network through the AP to be carried on the VoWiFi, thereby sharing the network pressure, improving the service quality of the service, and increasing the user experience.

For ease of understanding, based on the state in which the VoLTE and the VoWIFI are simultaneously camped, the specific process in the embodiment of the present invention is described below. Referring to FIG. 2, an embodiment of the service bearer in the embodiment of the present invention includes:

201. The communication terminal performs media negotiation with the communication peer end on the first access network according to the service request.

When the communication terminal needs to make a service connection with the communication peer, the communication terminal needs to initiate a service request to the communication peer as the called party side as the calling party side. In the process of the service request, the communication terminal can perform the service according to the service. Requesting media negotiation between the first access network and the communication peer, and selecting a codec format supported by both parties for each medium. The specific process of the media negotiation may be: the communication terminal sends an INVITE message to the communication peer through the control network element S-CSCF, and the message lists all media types that the communication terminal wishes to use in the current service, and the communication peer uses 183. (Session Progress) message returns the intersection of the communication terminal and the communication peer capability set when the response message is returned, that is, the communication peer returns multiple coding modes supported by each of the media types in the multiple codes supported by the communication terminal. After that, the communication terminal can select only based on the current status of its resources. A suitable set of coding schemes is sent to the communication peer using the RPACK message.

It should be noted that the communication terminal in this embodiment may be the calling party side, and the communication peer end may be the called party side. After being limited herein, the definition is not repeated. In a practical application, the communication peer end on the called party side in this embodiment may be a user terminal or a server, which is not limited herein.

It can be understood that the first access network in this embodiment is a preferred access network for the communication terminal to perform service connection default, and the first access network can be set, that is, the state in which VoLTE and VoWIFI are simultaneously resident. It can be set to VoLTE or VoWIFI, which is not limited here.

202. The communication terminal performs the first media resource reservation on the first access network according to the media negotiation result.

In the IMS network, the communication terminal and the communication peer use the signaling PDP context to deliver the session initiation protocol SIP message, and the media PDP context is used to transmit the media stream. The process of resource reservation is the process of establishing the media PDP context.

In this embodiment, after the communication terminal and the communication peer perform media negotiation, the communication terminal may perform the first media resource reservation in the first access network according to the media negotiation result, and after the media negotiation, if the communication terminal cannot be guaranteed When the communication peers complete the resource reservation, the communication peer will not be reminded by the method such as ringing. The first media resource reservation process is performed by the communication terminal by interacting with the underlying entity of the first access network. .

It can be understood that the media negotiation result in this embodiment may include a media type and/or a codec algorithm format, which is not limited herein.

203. If the communication terminal determines that the resource reserved by the first access network cannot meet the target resource, the communication terminal performs the second media resource reservation in the second access network.

If the communication terminal determines that the resource reserved by the first access network cannot meet the target resource, the communication terminal may perform the second media resource reservation in the second access network, where the target resource is a resource required for the target service corresponding to the service request. The resource reserved by the second access network is the remaining resources of the target resource that are not reserved in the first access network.

For example, in a practical application, assuming that a terminal needs to perform a multi-party video call, the resources required for the multi-party video call service are 6 channels of audio and 6 channels of video, and the first access network cannot reserve 6 channels of audio and 6 channels of video. When only 3 channels of audio and 3 channels of video can be reserved, the communication terminal can reserve the remaining 3 channels of audio and 3 channels of video in the second access network. It should be noted that in practical applications, the first The resources that can be reserved by the access network and the second access network are other categories and capacities. This embodiment is only an example.

204. After the communication terminal sends the first media resource reservation complete message to the communication peer end by using the control network element S-CSCF in the first access network and the second access network, the communication terminal receives the communication peer to complete the media resource. After the reservation is completed, the second media resource reservation completion message sent according to the first media resource reservation completion message;

After the communication terminal completes the media resource reservation of the first access network and the second access network, the first media resource reservation complete message may be sent to the communication peer through the S-CSCF, so that the communication peer is in itself. After the media resource reservation is completed, the communication terminal may receive the second media resource reservation complete message sent by the communication peer end according to the first media resource reservation complete message, where the first media resource reservation complete message includes the media corresponding to the target service. The way the stream is carried.

Specifically, in a practical application, after the communication terminal completes the first media resource reservation in the first access network, the communication terminal may send an UPDATE message to the S-CSCF in the first access network, and when the communication terminal is in the second access. After the network completes the second media resource reservation, the second access network may send an UPDATE message to the S-CSCF, and the UPDATE messages sent by the first access network and the second access network respectively identify the media corresponding to the target service. The bearer mode of the stream, for example, in the form of "m=video 3400RTP/AVP VoLTE, m=video 3400RTP/AVP VoWIFI", the S-CSCF aggregates the UPDATE message sent by the communication terminal through the first access network and the second access network. After the first media resource reservation complete message is sent to the application server, the application server sends a message indicating that VoLTE and VoWIFI are respectively identified in the first media resource reservation complete message to the corresponding communication peer, and the communication peer itself The media resource reservation is performed, and after the media resource reservation is completed and the first media resource reservation completion message sent by the application server is received, the communication terminal may be sent a second The media resource reservation completion message.

205. The communication terminal establishes a service connection with the communication peer end according to the second media resource reservation complete message, and carries the media stream in the first access network and the second access network according to the bearer mode.

After receiving the second media resource reservation complete message, the communication terminal indicates that the communication terminal and the communication peer reserve resources for the service to be performed, and the service can be smoothly performed, and then the communication peer can perform ringing, for example. The reminder that the communication terminal can establish a service connection with the communication peer end, and can perform the media flow corresponding to the target service carried in the first media resource reservation completion message. The bearer mode carries the media stream in the first access network and the second access network respectively, and the network pressure is shared.

In this embodiment, when the target service cannot be carried in the same access network, the media resource reservation may be separately performed on the first access network and the second access network to achieve the purpose of sharing the bearer of the target service, thereby effectively avoiding The target service cannot be connected between the communication terminal and the communication peer end, and at the same time, the network pressure can be alleviated, the service quality of the service can be improved, and the user experience can be increased.

It should be noted that, because the first access network may be VoLTE, the second access network may be VoWIFI, or the first access network may be VoWIFI, and the second access network may be VoLTE, so that the communication terminal performs service bearer. The specific methods are different, and the following are explained separately:

1. The first access network is VoLTE, and the second access network is VoWIFI:

In this embodiment, the first access network may be VoLTE, and the second access network may be a VoW IFI. Referring to FIG. 3 and FIG. 4, another embodiment of the service bearer method in the embodiment of the present invention includes:

301. The communication terminal performs media negotiation with the communication peer end in VoLTE according to the service request.

Based on the content illustrated in step 201 of the embodiment shown in FIG. 2, the communication terminal defaults to the first access network as VoLTE. When the communication terminal needs to initiate a service request to the communication peer, the communication terminal may according to the service in the process of requesting the service. Requesting media negotiation between VoLTE and the communication peer, and selecting a codec format supported by both parties for each medium.

302. The communication terminal performs the first media resource reservation on the VoLTE according to the media negotiation result.

Based on the content described in step 202 of the embodiment shown in FIG. 2, after completing the media negotiation with the communication peer, the communication terminal may perform the first media resource reservation in VoLTE according to the negotiation result.

303, the communication terminal determines whether the resource reserved by VoLTE meets the target resource, and if so, step 304 is performed, and if not, step 305 is performed;
