Problems solved by technology

In the existing solution, if the terminal is in the RRC connection state, after the RLF occurs, the terminal will re-select a suitable cell to camp on, and this selection process takes a certain amount of time, which in turn leads to service interruption; and the existing solution after the RFL The time consumption of the cell selection process is relatively long, resulting in a long service interruption time

[0082] like figure 1 As shown, the first embodiment of the present invention provides a cell control method, including:

[0083] Step 11, when the T310 timer on the terminal side starts, control the terminal to measure the neighboring cells of the serving cell;

[0084] Step 12, according to the signal of the serving cell or the signal of the neighboring cell during the running period of the T310 timer, it is determined that the radio link failure of the terminal occurs.

[0085] In the embodiment of the present invention, after receiving N310 consecutive out-of-sync indications reported by the physical layer (PL layer), the radio resource control layer (RRC layer) of the terminal starts a T310 timer. Wherein, N310 indicates the maximum number of downlink out-of-sync indications received by the terminal. And T310 is a timer indicating that the terminal fails to monitor the wireless link.

[0086] In the prior art, when the T310 timer expires, the terminal considers that a r...

Abstract

The invention provides a cell control method and device. The method comprises the following steps: controlling a terminal to measure a neighbor cell of a service cell when a T310 timer at a terminal side is started; and determining a fact that the terminal is failed in wireless link occurrence according to the signal of the service cell or the signal of the neighbor cell in the running period of the T310 timer. When the T310 timer is started, the terminal not only measures the service cell but also measures the neighbor cell before the wireless link occurrence is failed, and the speed of judging whether the wireless link is failed is improved; furthermore, the time of reselecting the cell by the terminal is shortened after the wireless link is failed in virtue of the measurement information of the neighbor cell before the wireless link is failed.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a cell control method and device. Background technique [0002] The Narrow Band Internet of Things (NB-IoT) work phase (Work Item, WI) was passed and started in the 3GPP Release 13 (Release 13) phase. The goal of the narrowband Internet WI phase is to standardize the wireless access of the Cellular Internet of Things (CIoT). The technology is expanded based on LTE / LTE-A, and the main network characteristics / objectives considered are: enhanced indoor coverage, support for a large number of low-speed device access, low latency sensitivity, reduced device cost, reduced device power consumption, optimized network architecture, etc. [0003] In order to be suitable for information transmission with small amount of data, the R13 NB-IoT project optimizes the system and introduces CP and UP solutions. [0004] 1. CP scheme (control plane scheme) [0005] In this solutio...
