Cell search method of terminal and related device and system

摘要

A cell search method of a terminal is provided. The terminal includes first and second network units. The first network unit camps a CS domain on a first network preferentially, and executes a CS domain service; the second network unit camps a PS domain on a second network preferentially, and executes a PS domain service; the first network unit receives a system message from a cell of the first network where the first network unit is located, and determines whether the system message carries neighboring cell information of the second network of the cell; and the second network unit searches for a cell of the second network after the first network unit determines that the system message carries the neighboring cell information of the second network of the cell. With the solutions, subscriber experience can be improved and cell search time of the terminal can be reduced.

1. A cell search method of a terminal, wherein the terminal comprises a first unit and a second unit, the terminal supports camping on a first network by the first unit and a second network by the second unit simultaneously,
wherein a circuit switching (CS) domain is preferentially camped on the first network, and a packet switching (PS) domain is preferentially camped on the second network; and the method comprising:
determining by the first unit, whether a system message received from a cell in the first network carries information of a neighboring cell, wherein the neighboring cell is located in the second network which is neighboring to the cell in the first network; andsearching for by the second unit, the neighboring cell based on the information of the neighboring cell after the first unit determining that the system message carries the information of the neighboring cell, wherein signal coverage of the first network is better than that of the second network, and a data transmission rate of the second network is higher than that of the first network;wherein the first unit camping in the CS domain and the PS domain on the first network based on first information of a subscriber in the first network stored in a single card of the terminal, and the second unit camping in the PS domain on the second network based on second information of the subscriber in the second network are both stored on a single card.
