Abstract

The embodiment of the invention discloses a cell switching method and a terminal, which are used to realize switching from a narrowband cell to a broadband cell and avoid call drop. The method in the embodiment of the present invention includes: the terminal participates in the current call in the narrowband service cell, and the terminal is registered in both the broadband service cell and the narrowband service cell; the terminal obtains the wireless resource information of the current call in the broadband service cell; the The terminal switches from the narrowband serving cell to the broadband serving cell according to the wireless resource information and continues the current call by using the wireless resource.

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...
