Embodiment 1

[0024] Such as figure 1 As shown, it is a flowchart of a terminal handover method according to an embodiment of the present invention. When the SBS finds that at least one of the DCD / UCD information content included in the SBS is not included by the TBS, the SBS instructs the terminal to update the TBS stored in the terminal. DCD / UCD information content, the method includes:

[0025] 101. The terminal receives a broadcast message sent by the serving base station SBS, where the broadcast message includes indication information that the terminal needs to update the downlink channel descriptor DCD / uplink channel descriptor UCD of the target base station TBS;

[0026] 102. After receiving the broadcast message, the terminal updates the DCD / UCD information content of the TBS stored in the terminal according to the DCD / UCD indication information in the broadcast message;

[0027] 103. The terminal uses the updated DCD / UCD information content to access the TBS.

[0028] Optionally, the above...

Embodiment 2

[0040] Such as image 3 Shown is a schematic structural diagram of a terminal according to an embodiment of the present invention, and the terminal includes:

[0041] The storage unit 30, a storage unit, is used to store the DCD / UCD information content of the TBS;

[0042] The receiving unit 31 is configured to receive a broadcast message sent by the serving base station SBS, where the broadcast message includes indication information that the DCD / UCD of the target base station TBS needs to be updated;

[0043] The update unit 32 is configured to update the DCD / UCD information content of the TBS stored in the storage unit 31 according to the DCD / UCD instruction information after the receiving unit 31 receives the broadcast message;

[0044] The switching unit 33 is configured to use the updated DCD / UCD information content to access the TBS.

[0045] Optionally, the broadcast message includes at least one DCD / UCD information content included by the SBS but not included by the TBS, and th...

Abstract

The embodiment of the invention provides methods for terminal switching and indication of terminal switching, a terminal and a serving base station (SBS). The method for terminal switching comprises the following steps that: a terminal receives a broadcast message sent by a SBS, wherein the broadcast message includes indication information for indicating that it is necessary for the terminal to update a downlink channel descriptor (DCD) / uplink channel descriptor (UCD) of a target base station (TBS); after the terminal receives the broadcast message, the TBS ' s DCD / UCD information content preserved in the terminal is updated according to the indication information of the DCD / UCD; and the terminal utilizes the updated DCD / UCD information content to access the TBS. According to the embodiment of the invention, the terminal can obtain correct DCD / UCD information of the TBS during the switching process, thereby reducing communication faults like error coding and improving a success rate of switching and network accessing.

Description

Technical field [0001] The present invention relates to the field of mobile communication technology, in particular to a method for terminal switching and instructing terminal switching, a terminal and a serving base station. Background technique [0002] The WiMAX (Worldwide Interoperability for Microwave Access) (802.16e) protocol was formulated by the IEEE (The Institute of Electrical and Electronics Engineers, the Institute of Electrical and Electronics Engineers) 802.16e working group. 802.16e can support some corresponding characteristics of mobile terminals, such as handover, IDLE (mobile phone in idle state) and so on. The reason for the handover of the mobile terminal is usually because the terminal's service quality is reduced. The reduction of the terminal's service quality can be caused by many reasons, for example, the location of the terminal has changed, or the location of the terminal has not changed but the environment has changed. In order to maintain the quali...
