Problems solved by technology

[0007] Considering that the terminal needs to scan other carriers of the serving cell and scan each carrier of the neighboring cell when switching, the scanning workload is heavy, the terminal power consumption is high, and the scanning time is too long, so that the terminal has no time to find a suitable carrier or the base station is lost. The present invention is proposed in view of the problem of wireless connection, for this reason, the main purpose of the present invention is to provide a terminal and its handover control method to solve the above-mentioned problems existing in the related art

example 1

[0042] 1. The base station sets two thresholds T for switching intra-BS and T inter-BS , in this example, T intra-BS greater than T inter-BS .

[0043] 2. The base station sets the two thresholds (T intra-BS and T inter-BS ) broadcast on the broadcast channel.

[0044] 3. The terminal receives the broadcast information from the broadcast channel, and saves the threshold value locally (corresponding to figure 1 in step S102).

[0045] 4. The terminal periodically detects the carrier signal strength of the current service, and compares the detection result with the threshold value.

[0046] If the terminal judges that the carrier signal strength of the current service is lower than the threshold T intra-BS , then the terminal starts to scan the signal strength of the carrier in the serving cell, and sends the scanning result to the base station. After receiving the scanning result sent by the terminal, the base station selects a suitable target carrier according to the h...

example 2

[0051] 1. The terminal locally sets two thresholds T for switching intra-BS and T inter-BS , in this example, T intra-BS greater than T inter-BS (corresponding to figure 1 in step S102).

[0052] 2. The terminal periodically detects the carrier signal strength of the current service, and compares the detection result with the threshold value.

[0053] If the terminal judges that the carrier signal strength of the current service is lower than the threshold T intra-BS , then the terminal starts to scan the signal strength of the carrier in the serving cell, and sends the scanning result to the base station. After receiving the scanning result sent by the terminal, the base station selects a suitable target carrier according to the handover decision algorithm inside the base station. And send control signaling to instruct the terminal to start the handover process in the base station, and the control signaling includes relevant information of the target carrier, such as car...

Abstract

The invention discloses a terminal and a method for switching control of the terminal. The method comprises the following steps of: setting a first predetermined threshold value and a second predetermined threshold value; scanning carrier waves in service cells of the terminal according to the first predetermined threshold value by the terminal; and / or scanning the carrier waves of adjacent cellsin the service cells according to the second predetermined threshold value. Through the processing, the terminal and the method can effectively reduce the scanning quantity of a single switching and ensure the continuity of services.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a terminal and a switching control method thereof. Background technique [0002] At present, in order to meet the requirement of high speed, in the system design of Institute for Electrical and Electronic Engineers (IEEE for short) 802.16m, the concept of multi-carrier is introduced, that is, a base station can be configured with multiple carriers . Wherein, these carriers can be divided into two categories: one is fully configured carriers, and the other is partially configured carriers. Wherein, the fully-configured carrier includes all necessary system-side information such as synchronization channels and control channels; while the partially-configured carrier may only include data transmission channels, or only include some necessary control messages, but not include synchronization channels. [0003] From the perspective of the terminal side, the carrier can...
