- the second indication module 86 may include: a sending unit 861, configured to send a system message update request message to the base station, where the system message update request message carries a system message for replacing a system message saved by the base station.
- the audit response message is not required to be judged, and the logical cell deletion process is not initiated to the base station, but the cell establishment request message is directly sent to the base station.
- the base station carrying the logical cell parameter and the indication information that is used to indicate that the message is triggered by the base station control right handover, so that the base station can directly establish a new logical cell according to the logical cell parameter and the indication information in the cell setup request message, and therefore, avoid Existing
- the deletion and the re-establishment of the logical cell on the base station are respectively triggered by different messages, and there is an idle time period between the deletion and the reconstruction of the logical cell on the base station, so that the resident UE does not receive the signal and the system message and causes the display. The problem of dropping the net.
- This embodiment provides a communication system, as shown in FIG. 9, including a base station 91 and an RNC 92.
- the base station 91 is configured to: after performing the auditing process, receive a cell setup request message sent by the RNC 92, where the cell setup request message carries a logical cell parameter and an indication information that is used to indicate that the message is triggered by the base station control right handover, and then And establishing a new logical cell according to the indication information and the logical cell parameter carried in the cell setup request message, and sending a cell establishment success message to the RNC 92.
- the RNC 92 is configured to send a cell setup request message to the base station 91 after performing the audit process, where the cell setup request message carries a logical cell parameter and indication information that is used to indicate that the message is triggered by the base station control right handover, and then receives the The cell establishment success message sent by the base station 91 after the new logical cell is established.
- the base station and the RNC in this embodiment may be the base station and the RNC described in Embodiment 4, and details are not described herein again.
- the present invention can be implemented by means of software plus necessary general hardware, and of course, by hardware, but in many cases, the former is a better implementation. .
- the technical solution of the present invention which is essential or contributes to the prior art, may be embodied in the form of a software product stored in a readable storage medium, such as a floppy disk of a computer.
- a hard disk or optical disk or the like includes instructions for causing a computer device (which may be a personal computer, a server, or a network device, etc.) to perform the methods described in various embodiments of the present invention.
- the embodiments of the present invention are mainly used in a WCDMA radio access network.
