Abstract

The invention discloses a method for identifying an emergency call in a TD-LTE system. The method includes the steps that A, a terminal makes a resource bearing request for an emergency call service to a core network; B, the core network receives the resource bearing request of the terminal, distributes new borne loads or modifies existing borne loads for the emergency call service according to a local strategy, and stores corresponding relationships between TFTs and PFs which correspond to the borne loads and the emergency call service; C, the core network receives service data sent to the terminal by a service server, extracts IP information and / or port information in a service data package and carries out matching on information stored in the PFs in the TFTs of the terminal; as for the successfully-matched PFs, if the corresponding relationships between the PFs and the emergency call service are stored by the core network, the service data package is identified to be emergency call service data. By means of the scheme, on the basis that network-side devices are not additionally arranged, cost is not increased, and the usage rate of resources of the core network is not influenced, the core network can rapidly and effectively identify the emergency call service.
