Embodiment 1
[0040] Such as figure 2 As shown, in this embodiment, the handover process specifically includes the following steps:
[0041] Step 21, the mobile terminal selects the target base station to be handed over according to the periodic measurement parameter information;
[0042] The mobile terminal can make a handover decision according to the signal strength of the serving base station and the adjacent base station obtained by periodic measurement. When the signal strength of an adjacent base station meets the handover condition, the terminal sets this base station as the target base station for handover;
[0043] In order to minimize the time spent in the handover process, the mobile terminal can also calculate and determine link budget information such as downlink timing deviation, frequency deviation, and path loss with the target base station based on the synchronization signal strength of the serving base station and adjacent base stations measured periodically. The mobile...
Embodiment 2
[0056] In this embodiment, when the mobile terminal accesses the target base station, it obtains one or more combinations of link budget information such as downlink timing deviation, frequency deviation and path loss with the target base station through the public channel, and according to the link budget information Realize downlink synchronization with the target base station.
[0057] Such as image 3 As shown, in this embodiment, the handover process specifically includes the following steps:
[0058] Step 31, the mobile terminal selects the target base station to be handed over according to the periodic measurement parameter information;
[0059] The mobile terminal can make a handover decision according to the signal strength of the serving base station and the adjacent base station obtained by periodic measurement. When the signal strength of an adjacent base station meets the handover condition, the terminal sets this base station as the target base station for hando...
Embodiment 3
[0072] This embodiment provides a terminal supporting the method of the present invention, and its specific implementation results are as follows Figure 4 As shown, it can mainly include the following processing units:
[0073] (1) a period measurement unit, used to measure the signal strength of the serving base station and adjacent base stations, parameter information such as synchronization signals within a predetermined period, and prepare for handover judgment;
[0074] (2) handover judging unit, used for judging whether to initiate handover according to the parameter information measured by the period measurement unit;
[0075] The terminal switching judging unit specifically includes:
[0076] The target base station selection module is used to select the target base station for handover according to the signal strength of the serving base station and adjacent base stations obtained by periodic measurement, and through predetermined selection conditions;
[0077] The...
