Embodiment Construction
[0023] In order to make the object, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.
[0024] The embodiment of the present invention provides a cell handover method, which is applied in the process of handing over the terminal from the source base station to the pico base station. The source base station in the embodiment of the present invention can be a macro base station or a pico base station. In the following embodiments, the source base station is A macro base station is taken as an example for description. The cell handover method is applicable to code division multiple access (CDMA 1X) and enhanced code division multiple access (CDMA EVDO) systems intervening between ...

The embodiment of the invention provides a cell switching method, device and system, the method comprises the following steps: a network side device receives a cell switching request sent from a source base station, the switching request comprises source base station information and terminal information required to switch; the network side device searches a triple consisting of corresponding relations among the source base station information, the terminal information and target pico base station information so as to obtain the target pico base station information corresponding to the terminal information required to switch; the triple is generated by the network side device according to obtained source base station information and call-drop terminal information and according to the call-drop terminal information and target pico base station sent by the target pico base station since the call-drop is generated when the terminal is switched to the target pico base station from the source base station; the network side device notifies the target pico base station to prepare the switching resource and sends a switching instruction to the terminal required to switch so that the terminal can be switched to the corresponding target pico base station.
Description
technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a cell switching method, device and system. Background technique [0002] In the wireless communication system, there are not only macro base stations (Macro cell) for wide coverage, micro base stations (Micro cell) for hot spot coverage with dense traffic / throughput, but also pico base stations ( Femto cell). Pico base stations are mainly used in homes, or shopping malls, office buildings, etc., and are developing rapidly as a new form of base station. [0003] At present, when a terminal is handed over from a pico base station to a macro base station, the pico base station automatically detects the signal of the macro base station, and adds a neighboring cell of the macro base station on the side of the pico base station to meet the handover requirement. However, no handover relationship is configured from the sector of the macro base station to the area ...
