Abstract

The present application discloses a cell camping method and device. The method includes: performing a cell search to obtain at least one new cell, and judging whether the first target cell supports the Internet Protocol Multimedia Subsystem IMS. The at least one new cell includes the The first target cell, if the first target cell supports the IMS, camp on the first target cell. In this application, when the mobile terminal moves to a new cell, by determining that the new cell supports IMS and then residing in the new cell, it can reduce the problem that the mobile terminal resides in a cell that does not support IMS and cause the user to be unable to communicate, and further improve the user experience. experience.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a cell camping method and device. Background technique [0002] The Code Division Multiple Access (CDMA) technology belongs to the 3rd Generation Partnership Project 2 (The 3rd Generation Partnership Project 2, 3GPP2) standard, and the Long Term Evolution (LTE) technology belongs to the 3GPP standard. These two network standards do not support mutual switching and reselection. Compared with the CDMA network, the LTE network has only the packet switching (Packet Switch, PS) domain and no circuit switching (Circuit Switched Domain, CS) domain, so the voice service solution based on the multimedia subsystem (IP Multimedia Subsystem, referred to as IMS) is adopted in LTE ( Voice over LTE, referred to as VoLTE) to implement voice services. The solution for the terminal device is to adopt a dual connection method, that is, the terminal device registers to the C...
