detailed description

It should be understood that the specific embodiments described herein are only used to explain the present disclosure and are not intended to limit the present disclosure.

In the following description, the use of suffixes such as “module”, “component”, or “unit” for representing elements is merely for the benefit of the description of the present disclosure, and it has no specific meaning itself. Therefore, "modules," "components," or "units" can be used in combination.

Figure 1 shows the IMS network-based converged communication RCS system in some cases. As shown in the diagram, the IMS network has a large architecture and a large number of network elements in the network for basic communications. The construction cost is high and the functions iterate slowly. At the same time, the same User data is stored in the IMS network and service layer, including HSS (Home Subscriber Server), VoWiFi AS (Voice On WiFi Application Server, call server) user data, IM AS (Instant Message Application Server) (Message server) user data, resulting in data redundancy, complex synchronization, and thus a large structure; In addition, the call server VoWiFI AS provided by the IMS network does not support multi-party video services.

In response to the above-mentioned pain points, the present disclosure provides the following embodiments. Through the technical solution for IMS at the bottom layer, the problem of message access and routing without IMS is solved, and the standard RCS service functions are fully implemented, which is not only applicable to operators. It is also suitable for corporate office. Because it is based on the standard GSMA specification, this device has a high degree of interconnection and interoperability. Compared with the current problem of incompatibility between OTT products, its solution has an important representative.

Example one

As shown in FIG. 2, this embodiment provides a converged communication system 100. The converged communication system 100 includes a terminal layer 110, an access layer 120, a service layer 130, and a data layer 140.

The terminal layer 110 includes an integrated communication RCS client 111. The RCS client 111 is a terminal device installed or integrated with an RCS client function, and is used by a user to handle RCS services on the terminal device side. Such as initiating business requests for account opening, registration, and conference creation.

The access layer 120 includes a session border controller SBC121, a session initiation protocol access point SIP AP122, an MSRP server 123, and an HTTP server 124. Among them, SBC121 is used for access control network elements, providing access control, network address translation NAT traversal, quality of service QOS control, access security, media firewall, media proxy, media codec conversion, and charging functions. SIP AP122 is used for session management and message routing network elements. It provides uplink and downlink message forwarding, login authentication, supports configuration and storage of multiple global contract templates, and triggers services to the application server AS based on the initial filtering rules in the user contract template. The MSRP server 123 is configured to provide a media session function of the message session relay protocol MSRP. The HTTP server 124 is used to provide a media transmission and reception function of the Hypertext Transfer Protocol HTTP. By adding SIP AP122, the access layer 120 can realize the most core session management and message routing functions without relying on the IMS network, solve the problem of message access and routing without IMS, and fully implement the standard RCS service functions. It is not only applicable to operators but also to corporate offices. Based on the standard GSMA specifications, this converged communication system 100 has a high degree of interconnection and interoperability, such as inter-operator interworking and cross-enterprise interworking.

The business layer 130 includes an instant messaging server IM131, a group chat service server GCAS132, an account opening proxy server 133, a unified authentication server 134, and a super conference and media unit 135. Among them, IM131 is used to provide one-to-one text message, picture, and file sending and receiving functions. GC AS132 is used to provide group chat service and group management service. The account opening proxy server 133 is responsible for receiving a unified authentication account opening request, and after preparing the account opening data, writes the account opening information into the user data center UDC141. The unified authentication server 134 is used to provide short-test account opening and HTTP authentication functions. The super conference and media unit 135 includes a super conference server for one-to-one audio and video and multi-party audio and video, and a media server for managing media. The business layer 130 adds one-on-one audio and video, multi-party audio and video by adding a super conference and media unit 135, which not only covers all audio and video functions of VoWiFi AS in the business layer under the IMS network, but also provides multi-party video that VoWiFi does not have. Features.

The data layer 140 includes a user data center UDC 141, a message queue center 142, and a rich media file service 143. Among them, UDC141 is used to manage global user data, and provides external query and write interfaces. The message queue center 142 is used to provide a global message queue cache for the IM 131. The rich media file server 143 is used to provide a global rich media file access function for the MSRP server 123 and the HTTP server 124. The data layer 140 is responsible for managing global user data without relying on the IMS network through the addition of UDC141. Centrally manages user data generated by RCS services through UDC141, and provides query and write interfaces to the outside world. Reduced network elements and improved overall performance.

In addition, the SIP AP 122 in this embodiment supports configuration and storage of multiple global contract templates, and each global contract template has a unique ID. Under a single global contract template, multiple IFC rules can be configured, and trigger conditions and priorities can be specified. When opening an account for a user, the account opening proxy server 133 specifies the contract template ID corresponding to the user in advance, and simultaneously maps the correspondence between the user IMPU (IM Public Identity) and the contract template ID to UDC141. Each user only Associate a global contract template. When the RCS client 111 uplink message is reported to SIP AP122 via SBC121, SIP AP122 obtains the contract template ID from the local cache (this data is obtained from UDC141 during user registration). SIP AP122 creates the requested session information, finds the IFC rule based on the contract template ID, and conveniently uses the IFC rule to determine the triggered service and records the current IFC trigger status. SIP AP122 triggers the AS according to the IFC rules, and records the current IFC trigger status. The AS returns the processing result. SIP AP122 finds the session information, determines the next trigger point, and updates the IFC trigger status at the same time until the service trigger ends.

As can be seen from FIG. 3, in this embodiment, the network element connection provided by the embodiment of the present disclosure includes: signaling: signaling here refers to SIP message, RCS client uplink messages are submitted to SIP APs via SBC, and SIP APs are triggered to each AS based on IFC; downlink messages are submitted to ASs by SIP APs, and SIP APs are delivered to RCS clients; Media: The media here includes MSRP ( Message Session Relay Protocol (Protocol, Message Session Relay Protocol), Real-time Transport Protocol (RTP), and HTTP, where MSRP and RTP are negotiated via signaling media, and the RCS client uplink message is sent directly to the corresponding via SBC Media server. The HTTP is directly connected to the HTTP server by the RCS client.
