Embodiment Construction

[0025] The basic idea of ​​the present invention is: for the situation where the signals of the macro base station and the private cell exist at the same time, when the signal quality of the private cell reaches the preset access threshold, the mobile terminal immediately accesses the private cell that it is allowed to access; further, when When the signal quality of the private cell is lower than the preset exit threshold, the mobile terminal is handed over to other private cells or macro base stations that the mobile terminal is allowed to access.

[0026] It should be noted that the access threshold and the exit threshold are used to determine the private cells that can be accessed or the private cells that need to exit. These two thresholds can be pre-set in the mobile terminal according to the demodulation signal capability of the private cell. set up.

[0027] In the present invention, when the mobile terminal initially accesses the private cell when starting up, and whe...

Abstract

The invention discloses a method for supporting access of a private cell, which comprises the following steps of: setting an access threshold of a private cell signal; searching whether the private cell capable of being accessed per se exists through a mobile terminal, if so, periodically scanning the signals of the private cell, and acquiring the current signal quality of the private cell; and if the signal quality of the private cell reaches the set access threshold, switching to the private cell. The invention also discloses a method for supporting switch of the private cell, which comprises the following steps of: periodically scanning the signal quality of the private cell accessed per se through the mobile terminal, and judging whether the signal quality of the private cell accessed per se is lower than an exit threshold, if so, exiting the private cell. The invention also discloses a device for supporting the access and the switch of the private cell and a switching terminal at the same time. The method, the device and the terminal can implement the access of the private cell and the switch among the private cell, a macro base station and other private cells.

Description

technical field [0001] The present invention relates to handover technology in network communication, in particular to a method and device for supporting private cell (FBS) access, and a method, device and terminal for supporting private cell handover. Background technique [0002] With the development of the network, the number of users is increasing day by day, and the required bandwidth is getting higher and higher. A large number of private cells have been established to meet users' different quality of service (QoS) requirements. The network planning of these private cells is mainly self-organized and autonomous, and only mobile terminals (MS) with private network rights are allowed to reside or access. [0003] Due to the relatively small coverage of private cells, there will be multiple types of network coverage in a certain network coverage area. For example, there may be a large number of private cells in the coverage of some macro base stations (MBS), that is, the...
