Returning method and device after offline of private network in high-speed mobile scene and terminal

Abstract

The present invention provides a returning method and device after offline of a private network in a high-speed mobile scene and a terminal. The method comprises: detecting the type of a district at present; when detecting the current district is off from a private network to a public network area, determining the current mobile speed state of the terminal; if the terminal is located at the high-speed mobile state in accordance with the high-speed mobile scene, searching the frequency points of the private network district according to the pre-stored private network district frequency point information list, and inquiring a target private network district satisfying a resident condition; and after the target private network district is inquired, initiating the resident process to the target private network district. The returning method and device after the offline of the private network in the high-speed mobile scene and the terminal can effectively solve the problem that the UE cannot return back to the private network after offline of the private network in the condition that the adjacent region relation between the private network and the public network along the highway is not configured so as to ensure the communication performance of the high-speed mobile terminal and improve the user experience.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a return method, device and terminal after a private network is disconnected from the network in a high-speed mobile scene. Background technique [0002] LTE (Long Term Evolution, long-term evolution) is the follow-up evolution technology of the third generation mobile communication (3G, 3rdGeneration). With its unique technical advantages such as high data rate, low delay, optimized network architecture, and larger carrier bandwidth, It has become the mainstream new generation broadband mobile communication standard in the world. [0003] At present, the scale of construction of high-speed railways is constantly expanding, and the speed of operation is also accelerating. The operating speed of many high-speed railways in my country has reached and exceeded 300km / h, and the operating speed of maglev trains can reach 430km / h. The impact of high-speed movement on mobil...
