The invention relates to a method of allocating Abis interface transmission channels in a packet cellular radio network, and to a network part utilizing the method. The method comprises () allocating fixedly a certain number of transmission channels to base-station-specific operations and maintenance signalling and to transceiver-specific telecommunication signalling; and () allocating dynamically, using in-band signalling, a necessary number of transmission channels to packet data transfer, the amount of packet data varying according to the modulation and coding scheme used on a Um interface.

Allocating Abis interface transmission channels in packet cellular radio network

The invention is a system, a method of transmitting messages selectively as text or non-text from an entity () in a network (and), and an entity in a network. A system in accordance with the invention includes at least one terminal (); a network containing the at least one terminal; an entity in the network which provides messages selectively as text or non-text to the network in a speech encoded form; and wherein the messages are transmitted in the speech encoded form by the network to the at least one terminal which reproduces the messages to a user thereof in either a text form or by a sound reproduction device of the at least one terminal.
