Embodiment approach 1

[0088] FIG. 3 is a schematic diagram of a basic processing flow of a method for controlling a transmission time limit according to Embodiment 1 of the present invention. In Embodiment 1 described below, when a new user makes a connection request to a time slot, it is not necessary to move the transmission time limit to the connected user in the time slot in advance, and the control process shown in FIG. 2 is used to transfer the connection request to the new user The sending time limit is changed from the usual sending time limit and allocated to the most suitable sending time limit position in the current situation, that is, when there are connected users, the sending time limit of the nearest user is shifted and directly allocated to the farthest sending time limit position constitute.

[0089] The basic operation of the transmission timing control method according to Embodiment 1 will be described with reference to FIG. 3 . In FIG. 3, the following steps S1 and S2 are exec...

Embodiment approach 2

[0133] A user who is connected to a TCH call in a certain time slot may sometimes need to switch the connection to a TCH in another time slot for some reason during the call. This is generally called TCH handover.

[0134] In other words, the so-called switching of the communication channel is equivalent to the process of allocating the transmission time limit position to the new user from the perspective of the time slot of the switching destination.

[0135] In Embodiment 2 of the present invention, for the user who wants to connect to the time slot switched by TCH, the control process shown in Figure 2 is adopted, and the sending time limit of the base station to send the synchronization pulse is offset from the sending time limit of the time slot before switching. , without shifting the transmission time limit to the connected users in the time slot in advance, but directly assigning the time limit position most suitable for the current situation in the time slot.

Abstract

The wireless base station shifts the transmission timing to the new user from the usual transmission timing and directly allocates it to the most suitable transmission timing position in the time slot where the mobile terminal device of the new user intends to connect. Therefore, it is not necessary to narrow the transmission time limit to the user connected earlier in the slot in advance.

Description

technical field [0001] The present invention relates to a wireless base station, a transmission timing control method, and a transmission timing control program, more specifically, to a wireless base station in which a plurality of mobile terminal devices can be connected by multiplexing paths in a mobile communication system, and a method for using such a wireless base station in such a wireless base station. A transmission timing control method and a transmission timing control program for optimizing a reception timing from a radio base station in a mobile terminal device while optimizing a reception timing from a mobile terminal device. Background technique [0002] In recent years, the rapid development of mobile communication systems (for example, Personal Handyphone System: hereinafter referred to as PHS), in order to improve the frequency utilization of radio waves, it is proposed that the same time slot of the same frequency can be space-divided, so that multiple A P...
