Description

A method and device for obtaining an address of a multimedia message service server

technical field

The present application relates to the technical field of trunking communication, and in particular, to a method and apparatus for obtaining an address of a multimedia server.

Background technique

The broadband trunking system is mainly composed of wireless terminals, trunking base stations, and trunking core networks, providing broadband access and broadband trunking functions. The multimedia message service is an important service in the trunking system, which can realize the transmission of pictures, audio, video, text and other information between different terminals, including a mobile terminal (User Equipment, UE) and a dispatch console (dispatch console, DC). In the cluster system, it is planned that a certain terminal belongs to a Multimedia Messaging Service Server (MMSS). During the MMS service, the terminal interacts with its home MMSS. Terminal A sends a multimedia message to terminal B or group G, and the message is forwarded to B or G through the MMSS. In order to ensure the normal sending and receiving of the message, the message must carry the correct MMSS. Address information.

In the Broadband Trunking Communication (B_TrunC) protocol, when the MMSS address changes, the enhanced home subscriber server (Evolved Home Subscriber Server, eHSS) switches to the terminal home switching control center (Trunking Control Function, H-TCF) Send a request message containing the IP address and port number of the latest MMSS. When the terminal initiates cluster registration to the network side again, the H-TCF will send the latest MMSS IP address and port number to the terminal through a message.

However, in the B_TrunC protocol, when the terminal's home MMSS address changes, the eHSS will carry the latest MMSS IP address and port number to send a request message to the terminal's home H-TCF, and the H-TCF will save the MMSS's IP address and port number. , only when the terminal initiates registration again, the H-TCF will send a message to inform the terminal of the latest IP address and port number of the MMSS. If the terminal initiates the multimedia message service before initiating the registration again, since the terminal does not know the latest address of the MMSS, the terminal will send a message to the unupdated MMSS address, resulting in a failure to send the message.

When detecting that the home MMSS address of the terminal changes, the eHSS sends a first request message to the H-TCF. Specifically, according to the definition of the B-TrunC standard, eHSS, H-TCF, and MME are important network elements of the cluster core network. The eHHS is mainly used to manage cluster information. When the address of the MMSS to which the cluster user belongs changes, the eHHS obtains the IP address and port number of the current MMSS, and will carry the IP address and port number of the current MMSS. A request message is sent to the H-TCF. H-TCF is mainly responsible for the scheduling management of cluster services. MME is a mobility management entity, responsible for mobility and bearer management, and also has cluster-related functions, and supports the process of requesting cluster services initiated by terminals.

S12: Store the IP address and port number of the current MMSS carried in the first request message in the H-TCF.

In this step, after the first request message is sent to the H-TCF, the IP address and port number of the current MMSS carried in the first request message are stored in the H-TCF. According to different service scenarios, the H-TCF sends the IP address and port number of the current MMSS to the terminal through different paths.

S13, the H-TCF sends an address request message carrying the IP address and port number of the current MMSS to the terminal.

In this step, when the H-TCF sends the address request message carrying the IP address and port number of the current MMSS to the terminal, it will pass through different network element devices. Specifically, the H-TCF is sent to the terminal through the MME or V-TCF/V-MME or directly. When sending a request message with each network element device, it will carry the IP address and port address of the current MMSS. The IP address and port address of the current MMSS are sent to the terminal through the request message sent between the network element devices.

S14, the terminal obtains the IP address and port number of the current MMSS.

Here, after acquiring the address request message sent above, the terminal stores the IP address and port number of the MMSS carried in the message. The terminal may send a message to the updated IP address and port number of the current MMSS.

In addition, between the step of the eHSS sending the first request message to the H-TCF and the step of storing the IP address and port number of the current MMSS carried in the first request message in the H-TCF, that is, when the H-TCF receives When the first request message is sent, the first request response message corresponding to the first request message is fed back to the eHSS. Meanwhile, according to the first request response message, it is determined that the H-TCF receives the IP address and port number of the current MMSS.
