Embodiment Construction

[0031] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0032] figure 1 It is a block diagram of a method for cell reselection provided by Embodiment 1 of the present invention, such as figure 1 As shown, the steps include:

[0033] Step S101: the user terminal obtains and saves reselection parameters related to adjacent cells, including cell VoLTE attributes.

[0034] Wherein, the cell VoLTE attribute of each cell is determined by the base station side according to the VoLTE supporting capability of the frequency band to which the cell belongs. That is to say, the base station side determines the VoLTE-supporting capability of the cell according to the VoLTE-supporting capability of the frequency band, and ...

Abstract

The invention discloses a cell reselection method and device, and relates to the technical field of mobile communication. The cell reselection method comprises the steps that a user terminal supporting VoLTE (Voice over Long Term Evolution) acquires and stores VoLTE attributes of cells; and the user terminal determines an optimal resident cell from a list of resident cells satisfying a reselection condition according to the VoLTE attributes of the cells and resides in the optimal resident cell when the user terminal, which supports VoLET and stays at an idle state, needs to perform cell reselection. The user terminal, which supports VoLTE and stays at an idle state, is enabled to preferentially reside in a cell supporting VoLTE, so that direct establishment of a voice service in the local cell can be realized, thereby reducing signaling interaction, and improving the wireless resource utilization rate and the paging efficiency of the terminal.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a cell reselection method and device. Background technique [0002] Voice service (Voice over LTE, VoLTE) based on Long Term Evolution (LTE) is an Internet Protocol (Internet Protocol, IP) data transmission technology that does not require the second generation of mobile communication technology (2nd Generation, 2G) / In the third-generation mobile communication technology (3rd-Generation, 3G) network, all services are carried on the fourth-generation mobile communication technology (4th-Generation, 4G) network, realizing the unification of data services and voice services under the same network. The LTE network not only provides high-speed data services, but also provides high-quality voice and video calls, and the voice and video under the LTE network are realized through VoLTE technology. [0003] In the existing LTE network system, the application scenarios of Vo...
