A network selection method and device

Abstract

The invention discloses a network selection method, which includes: generating a list of roaming base stations in different networks and a list of returning base stations in roaming in different networks according to the obtained types of base stations and the local public land mobile network PLMN of the operator to which each base station belongs. The type of the base station is the type of the base station negotiated and determined by the operator according to the coverage of the base station. The type of the base station includes the roaming base station or the returning base station of the roaming; according to the PLMN corresponding to the cell where the terminal is currently located, the list of the roaming base station and the roaming base station Return to the base station list, determine the base station to be accessed and access it. Through the PLMN corresponding to the cell where the terminal is currently located, the list of base stations for inter-network roaming and the list of base stations for inter-network roaming return, search for and obtain the base station to be accessed, which speeds up the speed for the terminal to select a network, reduces unnecessary roaming costs for users, and also enables The inter-network roaming settlement charges between operators are clear and clear.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a network selection method and device. Background technique [0002] With the development of communication technology, the investment and construction cost of 5G network has greatly increased. In edge areas, coverage and maintenance costs are difficult to recover due to low usage demand, resulting in serious idle network resources; while in indoor communication, operators with weak coverage signals have poor user experience. If different network roaming is adopted, the end user can automatically roam to the available operator network anytime, anywhere while keeping the mobile phone number and registered operator unchanged. The inter-network roaming refers to that the carrier network to which the terminal user belongs is carrier A. In the absence of carrier A's network coverage, the terminal user can obtain mobile communication services through carrier B's n...

AI Technical Summary

Problems solved by technology

[0004] Therefore, the present invention provides a network selection method and device to solve the problem in the prior art that the terminal cannot normally return to the home network of the terminal due to the inability of the terminal to independently and quickly select the wireless network to be accessed, which increases roaming costs. question
