Embodiment Construction

[0015] The following description focuses on an embodiment of the invention applicable to a TETRA cellular communication system. It will however be appreciated that the invention is not limited to this application, but is applicable to many other communication systems (eg ASTRO / APCO 25).

[0016] refer to figure 1 , shows one embodiment 100 of a communication network.

[0017] The nodes 116-128 of the network operate with increased bit rate traffic channels. Such an increase is obtained by reducing the energy-per-bit factor. When increasing the bit rate of an existing voice or low speed data network, the range of traffic channels affected by the increase will generally therefore be smaller than before the increase. Such range reduction is a result of transmitter power limitations (transmitting more bits with the same energy). These changes affect traffic channels rather than control channels by increasing the data speed in the network. As a result, the control channel rang...

Abstract

A wireless communications network (100) comprising a plurality of sites (102 - 114) each of which is served by a node (116 - 128), and said nodes (116 - 128) are connected with other elements of the network infrastructure. The network further comprises a plurality of mobile stations (130 - 134). At least one of said sites (102) has a first control channel and the remaining sites (104 - 114) do not have control channels, wherein said infrastructure is adapted, using said first control channel, to direct a mobile station (130 - 134) located in a site without a control channel (104 - 114) to a traffic channel.

Description

technical field [0001] The present invention relates generally to wireless communication networks, and more particularly to communication networks and methods for allocating mobile stations to traffic channels. Background technique [0002] In cellular communication systems such as Global System for Mobile Communications (GSM) and TETRA (Terrestrial Trunked Radio), the geographical area is divided into many cells, and each cell is served by a base station. A base station with a switching infrastructure is also called a base transceiver station The base station (BTS), known as the network node. The switching infrastructure supporting the BTS can be shared with other BTS. The system structure in the TETRA system is usually called the switching and management infrastructure (SwMI), which basically includes all A communication element. It consists of a Base Transceiver Station (BTS) connected to the conventional Public Switched Telephone Network (PSTN) or the Internet through a ...
