Problems solved by technology

For example: use short messages to complete services similar to emergency calls, and send an urgent short message to the emergency call center, but it is still difficult to implement such services as emergency calls with short messages. First of all, if the user is currently roaming , the short message center in the place of origin cannot know the settings of the emergency call center in the roaming place, so it cannot send the short message to the appropriate emergency call center; secondly, according to the needs of voice emergency calls, the emergency call should be in the user's Current location processing, that is, when the user roams to another network, the call should not be routed back to the user's home, but should be processed locally, and according to related technologies, emergency short messages will be routed to the home
To address these problems, no effective solutions have been proposed

Embodiment 1

[0023] figure 2 A flow chart of a method for implementing an emergency short message according to an embodiment of the present invention is shown, including the following steps:

[0024] Step 202, P-CSCF receives the emergency message request from the roaming user, and when the request address obtained by parsing from the emergency message request is the number of the emergency short message center, the emergency message request is forwarded to the E-CSCF (Emergency-CSCF, emergency session control functional entity);

[0025] Wherein, the number of the user's emergency short message center is provided by the visited network when the user roams to the visited network; specifically, the number of the emergency short message center can be provided in the following two ways: 1) Mobility management in the visited network During the attachment process initiated by the above-mentioned user, the network element MME provides the number of the emergency short message center to the use...

[0054] Figure 7 A flow chart of a method for implementing an emergency short message according to an embodiment of the present invention is shown. In this embodiment, the E-CSCF and the E-IP-SM-GW are deployed on the same network element device, including the following steps:

[0055] In step 701, the calling user UE1 initiates an emergency message request through the IMS network, wherein the request address is the number of the emergency short message center obtained through the network, and the message request carries a package packet in short message format, which contains message content, The recipient's address information and emergency short message center number;

[0056] Step 702, P-CSCF judges the request address in this message request, when P-CSCF receives this message request, judges the request address of message request, when finding that this address is emergency short message center number, sends this message request Forward to the E-CSCF / E-IP-SW-GW of the cu...

Abstract

The invention discloses a method and system for realizing an emergency short message, belonging to the communication field. The method comprises the following steps: a P-CSCF (Proxy Call Session Control Function) receives an emergency message request from a roaming user and transfers the emergency message request to an E-CSCF (Emergency Call Session Control Function) if a request address obtained by analyzing the emergency message request is a number of an emergency short message centre; and the E-CSCF inserts a corresponding PSAP (Public Safety Answering Point) address in the emergency message request according to position information of the user, converts the emergency message request into the emergency short message through an E-IP-SW-GW (Emergency-IP-Short-Message-Gateway), and forwards the emergency short message to the emergency short message centre. According to the method and the system disclosed by the invention, the request address in the emergency message request is the number of the emergency short message centre, therefore, a visiting network does not route the emergency message request to a home network of the user any longer by means of the number, but processes the emergency message request locally; and the system performance is improved.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and system for realizing emergency short messages. Background technique [0002] see figure 1 , is a structural diagram of an IMS (IP Multimedia Core Network Subsystem, IP Multimedia Subsystem) based on short messages, which includes a short message sender UE (User Equipment, user equipment) 101, P-CSCF (Proxy Call sessionControl Function, proxy session control function Entity) 102, S-CSCF (Serving CallSession Control Function, Serving CSCF) 103, execute the Serving Call Session Control function, IP-SM-GW (IP-Short-Message-Gateway, IP short message gateway) 104, execute IMS domain instant Message to CS (Circuit Switch, circuit switched) domain short message conversion, SMS-GMSC (Gateway MSC For Short Message Services, short message service gateway MSC) / SMS-IWMSC (Interworking MSC For Short Message Service, short message service interaction MSC ) 105, HSS (High S...
