Network selection method and system of multimode terminal

Abstract

The invention discloses a network selection method and system of a multimode terminal. The method comprises the following steps: a discovery step: a terminal receives base station related data broadcasted by a cellular network base station, and/or receives access point related data of a local area network access point; a selection step: the terminal pre-screens the base stations according to the base station related data, reserves the base stations meeting the base station basic access criterion, calculates base station access weight values of the reserved base stations according to the base station related data, and constructs a base station set of accessible terminals; and/or the access points are screened in advance according to the access point related data of the access points, the access points meeting the access point basic access criterion are reserved, the access weight values of the reserved access points are calculated according to the access point related data, and an access point set of accessible terminals is constructed; and an access step: the terminal selects at least one base station/access point for access from the base station set and/or the access point set according to the communication state data of the base station and the service quality data of the terminal, so that the spectrum utilization rate can be improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a network selection method and system for a multi-mode terminal. Background technique [0002] In order to cope with the contradiction between the rapid development of mobile communications and the scarcity of spectrum resources, the 3rd Generation Partnership Project (3rdGeneration Partnership Project, 3GPP) defined three major application scenarios of the 5th Generation (5G) communication system as enhanced mobile broadband services. (enhanced Mobile Broadband, eMBB), large-scale Internet of Things (massive Machine Type Communication, mMTC) and low-latency high-reliability services (Ultra ReliableLow Latency Communications, URLLC). Compared with the communication technologies required by these new application scenarios and business types, the existing 4G mobile communication technologies have many defects, such as high delay and low capacity. New technologies undoubtedl...
