Method for identifying emergency call in TD-LTE system

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.

Description

technical field [0001] The present application relates to the technical field of mobile communication, in particular to an emergency call identification method in a TD-LTE system. Background technique [0002] With the development of communication technology and the flattening of network architecture and the continuous emergence of various high-speed broadband mobile wireless access technologies, in order to ensure the competitiveness of the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project), and consider the evolution The wireless communication system can provide higher transmission rate with lower cost and shorter transmission delay, and at the same time support the mobility between 3GPP internal access systems and the mobility between 3GPP access systems and non-3GPP access systems Mobility, improving 3GPP system capabilities and performance, and reducing costs, 3GPP proposed the next-generation communication technology and architecture concept ...

Problems solved by technology

Since the core network is the core processing device in the LTE system, it maintains a large number of terminal devices and a large amount of user plane data, this method requires the core network to analyze all the user plane data of each terminal it maintains, which will cause core Serious waste of network resources, greatly increasing the load and processing complexity of the core network, seriously reducing data exchange processing capacity and business carrying capacity
