Abstract

The embodiment of the invention discloses a cell switching method and a terminal which are used for realizing switching from a narrowband cell to a broadband cell and avoiding call missing. The method comprises the steps that the terminal participates in a current call in the narrowband service cell, wherein the terminal is registered in both the broadband service cell and the narrowband service cell; the terminal acquires information of wireless resources of the current call in the broadband service cell; the terminal switches from the narrowband service cell to the broadband service cell according to the information of the wireless resource and continues the current call through the wireless resources.

Description

technical field [0001] The embodiment of the present invention relates to the field of communication technologies, and in particular to a cell handover method, a terminal and core network equipment. Background technique [0002] In the field of professional trunking communication, Police Digital Trunking (PDT) system, Terrestrial Trunked Radio (Tetra) system and P25 (Project25) are several mainstream systems, all of which belong to narrowband trunking systems. Narrowband trunking communication systems such as PDT, Tetra, and P25 can provide users with good narrowband voice services, but they have the disadvantage of low transmission rate in data services, which cannot meet the growing needs of broadband services such as images and data. The problem is that the industry is generally optimistic about the broadband and narrowband cluster integration of narrowband systems and broadband systems. Broadband systems such as Long Term Evolution (LTE) systems, broadband and narrowband...
