Problems solved by technology

However, the base station BS has already used the time slot S1 to communicate with the wireless relay device 11, so even if the wireless relay device 11 with the highest signal reception strength and the base station BS with the second largest signal reception strength are selected from the perspective of the mobile station PS, the In fact, the two base stations are one, which essentially becomes a situation where one time slot is used to communicate with one base station, and it is difficult to obtain the original communication speed

Embodiment approach 1

[0028] FIG. 1 shows a wireless relay device according to Embodiment 1 of the present invention. The wireless relay device 1 is used in wireless communication systems such as PHS for relaying wireless communication between the mobile station PS and the base station BS in the wireless communication system of the 4-channel multi-channel TDMA-TDD method, and performs the communication between the mobile station PS and the base station BS. Packet switching between BSs and circuit switching wireless communication are relayed, and the time slot configuration is as shown in Fig. 2 as in the previous use case, and corresponds to communication at a maximum of 128 kbps.

[0029] As shown in FIG. 1 , the wireless relay device 1 is composed of a BS-side wireless communication unit 2 that communicates with the base station BS through an antenna 2a facing the base station BS, and communicates with the mobile station PS through an antenna 3a facing the mobile station PS. The PS-side wireless ...

Embodiment approach 2

[0036] FIG. 5 is a sequence diagram illustrating a wireless relay operation in a wireless relay method according to Embodiment 2 of the present invention in which wireless communication between the base station BS and the mobile station PS is relayed by the wireless relay device 1 in FIG. 1 , When the wireless relay device 1 uses 1 time slot to relay the call control of the packet switching P of 32 kbps between the base station BS and the mobile station PS, when the circuit switching L of 64 kbps using two time slots When a call control request (connection channel establishment request SCCH) is transmitted from the mobile station PS to the base station BS via the wireless relay device 1, the base station BS transmits allocation of time slots for the line (connection channel allocation SCCH) to the wireless relay device 1. The wireless relay device 1 transmits the same time slot (connection channel allocation SCCH) as the time slot allocated by the base station BS to the mobile ...

Embodiment approach 3

[0040] FIG. 7 is a diagram illustrating the processing procedure of the wireless relay operation in the wireless relay method according to Embodiment 3 of the present invention, in which wireless communication between the base station BS and the mobile station PS is relayed by the wireless relay device 1 in FIG. 1 . flow chart. This embodiment describes the operation in the case where interference occurs in the call control of the circuit switching when the wireless relay device 1 performs hybrid relay of the respective call controls of the packet switching and the circuit switching. First, relay processing of circuit switching and packet switching call control between the base station BS and mobile station PS is started (step K21), and hybrid relaying of packet switching and circuit switching call control as described in Embodiment 2 In the ongoing state (step K22), it is judged whether interference has occurred in the call control of the circuit switching L (step K23), and i...

Abstract

To provide a radio relay apparatus capable of obtaining an expected transmission speed, even if a mobile station duplicately selects the same base station as a base station used for the call control of packet exchange. The radio relay apparatus 1 is configured of a BS side radio communication section 2 for performing radio communication with a base station BS via an antenna 2a for the base station BS, a PS side radio communication section 3 for performing radio communication with a mobile station PS via an antenna 3a for the mobile station PS, and a control unit 4 for controlling transmission / reception operations of the sections 2 and 3. A signal of each of call control of packet exchange P and line switching L received by the apparatus 1 from the base station BS and the mobile station PS is relayed and transmitted to the base station BS or the mobile station PS by using the same slot as a received slot.

Description

[0001] This application is a divisional application based on the patent application with the filing date being May 20, 2004, the application number being 2004100458213, and the title of the invention being "wireless relay device and wireless relay method". technical field [0002] The present invention relates to a wireless relay device and a wireless relay method for relaying wireless communication between a mobile station and a base station through a wireless communication system. Background technique [0003] As shown in FIG. 12, there is conventionally a wireless relay for relaying wireless communication between a mobile station PS and a base station BS in a four-channel multiplex TDMA-TDD (Time Division Multiple Access-Time Division Duplex) wireless communication system. device 11. The wireless relay device 11 is equipped with two systems, the BS side wireless communication unit 12 and the PS side wireless communication unit 13, and communicates with the base station BS...
