To reduce interference in a communication system (,), a communication unit (,) is arranged to initiate establishment of a radio frequency communication with a base station (,) by transmitting a system access request on a dedicated, wide area control channel. Upon receipt of the system access request, a base station (,) of the communication system of FIG.,responds by forming a narrowbeam control channel to the communication unit and transmitting system control information to the communication unit on the narrowbeam control channel, the system control information transmitted from the array of antenna elements and arranged to identify a narrowbeam communication resource for use in the radio communication. The communication unit (,), upon receiving the system control information, then configures itself to utilise the narrowbeam communication resource for the radio communication.

Communication system with a beamformed control channel and method of system control

A communications operating system is provided herein. The communications operating system having a common communication system comprising a radio frequency transceiving means for transmitting and receiving radio frequency signals and a system list means for storing a list of communication systems available. The system also includes a feature list means for storing a list of feature programs, where the feature programs comprise at least one of an enabling program to enable resident functions, a high-level design specification, and an executable feature specification.

Radio communications device and method

A method for a network in a multi-network system to obtain access information for a subscriber unit (104) (SU) involves requesting (1306) access information from an access server (110) which determines (1208) whether a group to which the SU belongs can access the network or another network from the SU location. The access server (110) can also send (1228) information to a network which describes which other networks the SU group can access from the SU location. An access server apparatus (1800) includes a processor (1802) for making access decisions in a multi-network system, a memory device (1804) for storing access information (1100) for various networks, and at least one network interface (1806). A gateway (GW) apparatus (2000) contacts an access server (110) to obtain access information. An SU apparatus (1900) includes a processor (1902) for using information from the access server (110) to access a network.

A method for handing off calls between differing radio telecommunication networks recognizes (302) a desire for an inter-network hand-off. When a Subscriber Unit (120) (SU) identifies (304) a new network, a hand-off with the new network can be requested (320). When the SU (120) does not identify (304) a new network, the old network requests (314) location information relevant to an inter-network hand-off from a Location Inter-Working Server (200) (LIWS). The LIWS (200) provides information about other networks which provide service to the SU location and, when another network provides service to the SU location, a hand-off with the other network can be requested (320).

Method and apparatus for handing off calls between differing radio

A method as shown in FIG. 2 for allocating resources in a radio communications system having a plurality of communications resources for at least one receiver and transmitter to communicate over where the communications resources have signal levels which vary due to a multipath environment resulting in periods of poor communication quality over at least one particular communications resource including measuring at a first receiver a parameter indicative of a quality of communications between the first receiver and a first transmitter over a currently assigned communications resource and determining whether to allocate a different communications resource based on the measured parameter in order to effectively reduce periods of poor communications quality between the first receiver and the first transmitter.
