Problems solved by technology

When there is no caller information, the route will also be forced. If the user dials the emergency number by mistake without inserting the card, the switch cannot lock the caller after the route is connected, which is inconvenient for the called party to deal with the emergency.

Embodiment Construction

[0027] Since the emergency call service request and the emergency call establishment request do not carry the called number, when it is necessary to route to a different emergency call center according to the emergency number, the emergency category information must be carried in the request. In the present invention, if the terminal can obtain the emergency category corresponding to the emergency call number, the emergency call establishment request sent by the terminal to the switch carries the emergency category information, and the switch can translate the emergency category information into the corresponding emergency call number for subsequent routing. If the switch cannot obtain the emergency category information, it cannot determine which emergency call center the route is connected to. At this time, the switch will play a recording notification.

[0028] Such as figure 1 As shown, it is a flow chart of an emergency call processing method of the present invention, incl...

Background technique [0002] Emergency call services are generally provided in mobile communication networks. The emergency call service should be handled by a unified call center, and the emergency number of 2G is only 112. In an ideal situation, no matter whether it is fire alarm, bandit police or first aid, it will be routed to the call center first, and then manually connected to the corresponding emergency call center for fire alarm, bandit police or first aid. Because many countries do not have the capacity to integrate all emergency call centers, emergency calls are handled differently. [0003] In an existing processing method, the 112 call center does not exist. Regardless of whether the terminal has a card inserted, the user dials 112, and the terminal only sends an...
