Problems solved by technology

[0013] However, according to the current situation of multimedia broadcasting services, users must activate multimedia services locally to receive these services, so the current multimedia service network cannot enable every user to get emergency information in an emergency
[0014] Therefore, in some cases, it is necessary to enable all users in a certain area to receive emergency information, but unfortunately, no relevant technical solutions have been proposed so far

example 1

[0048] Example 1: Operation Example of Step S202

[0049] Fig. 3 is a flow chart of session start processing of the BM-SC for emergency broadcast in the method according to the embodiment of the present invention. As shown in Figure 3, it specifically includes the following steps:

[0050] Step 300, BM-SC receives a request for emergency broadcast, which generally comes from the customer service system of the BM-SC operator, or a third party authorized by the operator to send emergency broadcast;

[0051] Step 310, the BM-SC reads the configuration message, and decides according to the configuration whether to send a session start request when sending the emergency broadcast;

[0052] Step 320, if it is judged in step 310 that a session request message needs to be sent, the BM-SC sends a session request to the GGSN, and the area in the session request is determined by the operator in the BM-SC configuration;

[0053] Step 330, the BM-SC judges whether the emergency broadcast...

[0060] Example 2: Operation Example of Step S202

[0061] Fig. 4 is a flow chart of session start processing of GGSN, SGSN, RNC / BSC for emergency broadcast in the method according to the embodiment of the present invention. As shown in Figure 4, it specifically includes the following steps:

[0062] Step 400, GGSN, SGSN, RNC / BSC receive a multimedia session start request message from an uplink node;

[0063] Step 410, judging whether the message belongs to an emergency broadcast according to the parameters in the session start request message;

[0064] Step 420, if it is judged in step 410 that it is not an emergency broadcast, then retain all the processing procedures of the original protocol; and

[0065] Step 430, if it is judged in step 410 that the message is an emergency broadcast, then immediately send a session start request message to the downlink node according to the service area list in the session start message, and carry an emergency identifier.

[0067] Fig. 5 is a flow chart of GGSN, SGSN, RNC / BSC implementing emergency broadcast through Gi interface in the emergency broadcast method based on multimedia broadcast according to an embodiment of the present invention. As shown in Figure 5, it specifically includes the following steps:

[0068] Step 500, GGSN, SGSN, and RNC / BSC receive multimedia broadcast content sent from uplink nodes through the Gi interface;

[0069] Step 510, judging whether it is an emergency broadcast according to the parameters of the multimedia broadcast content;

[0070] Step 520, if it is judged in step 510 that it is not an emergency broadcast, then retain all the processing procedures of the original protocol;

[0071] Step 530, if it is determined in step 510 that it is an emergency broadcast, then first determine whether a bearer plane has been established for the emergency broadcast service;

[0072] Step 540, if it is determined in ste...

Abstract

The method comprises: 202) when the multimedia server is an emergency service, a emergency broadcast identifier for showing the multicast service is an emergency broadcast service is loaded into the multimedia service broadcast, and the multimedia service is broadcasted; 204) after receiving the multimedia service, according to the emergency broadcast identifier, each net element is forced to send the multimedia server to the downlink net element; 206) user end (UE) automatically receives the emergency broadcast in case of not enabling the multimedia broadcast service.

Description

technical field [0001] The present invention relates to the communication field, and in particular, to an emergency broadcasting method based on multimedia broadcasting. Background technique [0002] Multimedia broadcast / multicast (MBMS) is a point-to-multipoint service that enables one data source to send data to multiple users. MBMS can not only realize plain text low-rate message multicast and broadcast, but also realize multicast and broadcast of high-speed multimedia services. MBMS is based on WCDMA / TD-SCDMA / GSM (Wideband Code Division Multiple Access / Time Division-Synchronous Code Division Multiple Access / Global System for Mobile Communications) packet network, by adding some new functional entities (for example, broadcast multicast service Center (BM-SC)), to the existing packet domain functional entities (for example, Serving GPRS Support Node (SGSN), GPRS Gateway Support Node (GGSN), Radio Network Controller (RNC) and User Equipment (UE)) Add MBMS function and def...
