A radio local loop (RLL) system which can automatically reallocate fixed subscriber units to a different radio domain without expending the costly and time consuming efforts needed to manually readjust antennas. By transmitting a code to the fixed subscriber unit, whereby the code identifies a second radio domain, an antenna associated with the fixed subscriber unit automatically adjusts such that said subscriber unit can communicate with the second domain using a radio channel. While the scan angle of the antenna is adjusted, the fixed subscriber unit derives a signal quality value for a number of radio channels. Based on the signal quality values, the RLL system determines whether the second radio domain exhibits superior signal quality characteristics as compared to the first radio domain. If the second radio domain exhibits superior signal quality characteristics than the first radio domain, the fixed subscriber unit is reallocated to the second domain. Further, the fixed subscriber unit automatically performs a dynamic channel selection scheme. This scheme allows the fixed subscriber unit to select the available traffic channel that exhibits the best signal quality characteristics for establishing a connection.

Method and communications system with automatic reallocation of subscriber units

In a telecommunication system including a plurality of communication networks a user is provided with a consistent set of services when roaming through the networks using a telecommunication device, such as radio telephone. Data specific to services of the telecommunication system are stored in memory means of the telecommunication device and the communication networks. Service specific data are exchanged between the telecommunication device and the communication networks when accessing a communication network and/or a particular service thereof. The exchanged data are processed such to provide services to the user in accordance with a user interface known to the user.
