Abstract: In a communication system at least one operational criterion is applied for a group of one or more users. On the basis of such operational criterion, one or more interface rules are generated. An interface rule includes information that identifies an application that is capable of utilizing two or more communication interfaces, and also a function for determining a communication interface to be applied by that application in communications of the group of one or more users. A profile that includes interface rules generated on the basis of operational criteria to be applied for a user is created and stored in a user terminal of the user. Use of applications can be matched with operational requirements posed on or by the user, without substantial need to change the applications and/or the configuration of the terminal due to the matching.

Abstract: A communication system includes a plurality of channels, a first service that utilizes at least a first channel for transmission, and a second service that utilizes at least a second channel for transmission. Operating means are provided for operating the first service in connection with the second service, so that the first service can utilize the second channel. Adjusting means are provided for adjusting the utilization of the second channel by the second service at least during the connected operation of the first and the second service. The utilization of a channel whose capacity is essentially dynamically adjustable is facilitated by a service that, according to the pre-defined protocols, is directed to use a channel whose capacity is more statically adjustable.

Abstract: A radio system comprising a switching and management infrastructure arranged to deliver voice and data between a plurality of communicating parties, and a mobile station. Said radio system comprises a multiplicity of traffic channels, each traffic channel being associated with a unique coding scheme. The switching and management infrastructure is arranged to receive a plurality of paging messages from a plurality of communicating parties, and to combine the paging messages received during a pre-defined time period into a paging frame comprising a multiplicity of address data blocks for identifying the mobile station(s) for which the paging frame comprises a paging message. At least one of the traffic channels of the radio system is dedicated to delivery of downlink paging messages, and associated with a coding scheme that comprises at least one error protection algorithm.

Abstract: The invention concerns a system for transmitting information in a digital radio network system (12) between at least two modes of operation, which may be—a direct mode operation (DMO) between two terminal devices (10.1, 10.2) operating independently of the physical radio network system (21) and—a trunked mode operation (TMO) supporting distribution of network resources and operating in the physical radio network system (21). The transmission takes place with the aid of a special gateway unit (22), wherein the gateway unit (22)—listens to each or to a chosen mode of operation (DMO, TMO),—receives the transmission occurring in one mode of operation (TMO, DMO), and—transmits the received transmission to the other mode of operation (DMO, TMO). The gateway unit (22) is formed of two terminal devices (12.1, 12.2) supporting each mode of operation, and whose data transfer interface (23.3*, 23.
