Embodiment Construction

[0045] The following description focuses on an embodiment of the present invention applicable to text messaging in a TETRA cellular communication system. However, it should be realized that the invention is not limited to this application, but may be applicable to many other cellular communication systems, including eg GSM or UMTS cellular communication systems.

[0046] FIG. 1 illustrates a TETRA cellular communication system 100 according to a first embodiment of the present invention. For the sake of clarity and simplicity, only the elements of the communication system 100 necessary to describe the inventive concepts of the embodiments are included, and it should be recognized that actual cellular communication systems will typically include substantial additional functionality.

[0047] In FIG. 1, a base station 101 supports a plurality of remote units 103, 105, two remote units being shown. A remote unit is typically a subscriber unit, wireless user equipment, mobile sta...

Abstract

A base station (101) for a cellular communication system is coupled to a fixed network (107) and receives text strings for transmission to remote units (103, 105). The base station includes a receive processor (111) which receives a first text string encoded in a first encoding format. The receive processor (111) is coupled to a conversion processor (113) which converts the first text string to a second text string at least partially encoded in a second encoding format. The first encoding format may be an UTF-8 or UTF-16 text encoding format and the second encoding format may be an ASCII text encoding format. The conversion processor (113) is coupled to a transceiver (115) which transmits the second text string to the remote units (103, 105).

Description

technical field [0001] The present invention relates to a cellular communication system, a network element and a method of operation thereof, and in particular, to the communication of text strings in a cellular communication system. Background technique [0002] In a cellular communication system, a geographical area is divided into a number of cells, each cell being served by a base station. The base stations are interconnected by a fixed network that can transfer data between the base stations. The remote unit is served via a wireless communication link by the base station of the cell in which the remote unit is located. [0003] As a mobile remote unit moves, it may move from the coverage area of ​​one base station to the coverage area of ​​another base station, ie, from one cell to another. As the remote unit moves toward the new base station, it enters an area where the coverage of the two base stations overlaps, and in this overlapping area, the remote unit becomes ...
