Method for handling emergency service in network communication

摘要

The present invention discloses a method for handling an emergency service in a network communication, including: sending, by an emergency service initiating side, an emergency service identifier together with an emergency service to a network side; and allocating, by the network side, resource to the emergency service with a priority higher than those of normal services. With the present invention, a corresponding emergency service may be identified effectively in a network provided with an independent bearer-control-layer entity, and a resource may be allocated to the emergency service in accordance with a special resource allocation policy. Therefore, it is possible to guarantee the connectivity and the resource for the emergency service as requested in the network, and hence to reduce an unexpected and unnecessary loss.
