Method for controlling functions for changing radio areas of communications terminal devices
First Claim
1. A method for controlling functions for change of radio area of communications terminal devices in a program module structure of a subscriber module of a wireless communications system, the subscriber module being connected at a subscriber side with at least one base station for wireless connection of at least one communications terminal device, and at a switching side said subscriber module being connected with a central communications installation for creation of access to a communications network, comprising the steps of:
- assigning a highest priority to program modules for controlling hardware components of the subscriber module-and to program modules for controlling physical communications connections of the subscriber module with a central switching control and with the at least one base station;
assigning a second highest priority to program modules for signaling generation of tone and call signals, to program modules for processing of a radio area change process of a communications terminal device connected tirelessly to a base station, to program modules for safeguarding communication with the communications terminal devices, and with the central communications installation;
assigning a third highest priority to program modules for processing communications protocols with the base stations and the communications terminal devices, to program modules for event recognition and event allocation of events transmitted by the communications terminal devices, and to program modules for switching;
assigning a fourth-highest priority to an arbitration program module for reading out of safeguarded and allocated events and for calling up of a program module designated by a located event;
assigning a lowest priority to program modules having management and test functions; and
processing the program modules according to said assigned priorities.

Abstract
In a method for controlling functions for a change of radio area of communications terminal devices, in a program module structure of a subscriber module of wireless communications systems, a higher priority is allocated to the program modules for processing of the radio area change process than to the program modules for processing the communications protocols and to the program modules for switching. The program modules are processed according to their priority. Through the preferential treatment of the handover process, the system resources, in particular the processing resources, are concentrated on the handover process. In the context of the total load capacity of the subscriber module of the wireless communications system, the communications connection during a handover process is thus maintained with high reliability by effecting a rapid changeover to the new communications path, whereby disturbances are also avoided by means of the rapid changeover.

8. A system for controlling functions for change of radio area of a communications terminal device comprising:
-
a subscriber module having a program module structure and connected at a subscriber end with at least one base station for wireless connection to at least one communications terminal device and at a switching end with a central communications installation for creating access to a communications network; means for allocation of priorities to program modules of the program module structure such that a highest priority is allocated to program modules for controlling hardware components of the subscriber module and to program modules for controlling physical communications connections of the subscriber module with a central switching control and with the at least one base station, a second highest priority is allocated to program modules for signaling generation of tone and call signals, to program modules for processing of a radio area change process of the communications terminal device connected wirelessly to the base station, and to program modules for safeguarding communication with the communications terminal device and with the central communications installation, a third highest priority is allocated to program modules for processing of communications protocols with the at lest one base station and with the communications terminal device, to program modules for event recognition and event allocation of events transmitted by the communications terminal device and to program modules for switching, a fourth highest priority is allocated to an arbitration program module for reading out safeguarded and allocated events and for calling up a program module designated by a located event, and a lowest priority is allocated to program modules having management and test functions; and means for processing the program modules according to the allocated priorities. - View Dependent Claims (9, 10, 11)
