Embodiment Construction

[0054] The common structure of each embodiment: Fig. 2 to Fig. 4

[0055] FIG. 2 specifically shows the radio network control device 100 and the mobile terminal 200 in the system shown in FIG. 1 .

[0056] The radio network control apparatus 100 includes: a call controller 101 for controlling a call connection of the mobile terminal 200, a radio manager 110 for managing wireless signal transmission / reception with the mobile terminal 200, and a mobile state monitor 110 for monitoring the mobile terminal 200. The mobile monitoring unit 120, the resource manager 130 for managing the resources of the radio network control device 100 itself, and the database DB.

[0057] In addition, the call controller 101 includes a timing controller 102 for controlling a reconnection timer, a reconnection controller 103 for detecting disappearance of a radio signal and controlling reconnection, and a mobile device for managing call information and a call state. Terminal Manager 104.

Abstract

In a reconnection control method and device for mobile terminal which can automatically change an optimum reconnection time according to various states, a handover history of a mobile terminal is managed, a next handover destination cell of the mobile terminal is predicted from the handover history. When it is detected that the predicted handover destination cell corresponds to a radio wave-faulted area, a predetermined reconnection time for the mobile terminal is changed. When the radio wave-faulted area is a non-service area where a cell is not mounted, the predetermined reconnection time is reduced. When the radio wave-faulted area is a temporary radio wave-faulted area, the predetermined reconnection time is extended. When the radio wave faulted area is a congestion area, the predetermined reconnection time is reduced.

Description

technical field [0001] The present invention relates to a reconnection control method and device for a mobile terminal, in particular to a reconnection control method and device for a mobile terminal in a radio network control device in a mobile radio system. Background technique [0002] FIG. 13 shows the sequence from call setup to reconnection known in the prior art of mobile radio systems. In this sequence, when the mobile terminal (user equipment) 200 first moves to the movement destination cell (handover destination cell), a connection request ( In step S100). [0003] In the radio network control device 100, the call controller 101 receives a connection request, and then sends the connection request (at step S101) to the radio manager 100, so that a radio zone connection is performed between the terminal 200 and the radio network control device 100 Or connect (at step S102), which results in handover completion. [0004] After that, the call controllers 203 and 101...
