Method and radio communications system for controlling connections for calls to and by radio subscribers
First Claim
1. A method for connection control in a radio communications system during calls from and to radio subscribers, said radio communication system comprising a radio subsystem via which communications terminals which allow access by said radio subscribers can be connected in an associated radio area, and a switching center for switching through connections, comprising:
- routing said connections between said radio subsystem and said switching center via a radio transmission unit, said routing comprising;
switching through signaling connections, and not switching through traffic channel connections, from said radio transmission unit to said switching center when a call within a radio area is between radio subscribers within a same said radio area,switching through signaling connections, and not switching through traffic channel connections, from said radio transmission unit to said switching center when a call is between radio subscribers in different radio areas,switching traffic channel connections by said radio transmission unit between a first radio subsystem and a second radio subsystem for a case of a call within a radio area from when a call is between radio subscribers in different radio areas.

Abstract
Based on a radio communications system (KN) having at least one radio subsystem (RSS) for access by the radio subscribers in an associated radio area (RRA) and having at least one switching center (MSC) for switching through connections, the method and the radio communications system according to the invention provide for the connections between the radio subsystem and the switching center to be routed via a radio transmission unit (UE) in such a way, that, in the case of a call within a radio area between radio subscribers within the same radio area (RRA), or in the case of a call between radio subscribers in different radio areas (RRA, RRA*), only signaling connections (si) are switched through from the radio transmission unit to the switching center, and that traffic channel connections (ni) are switched by the radio transmission unit between a first radio subsystem (RSS) and a second radio subsystem (RSS*) in the case of a call within a radio area from the radio subsystem (RSS) itself or in the case of a call between radio subscribers in different radio areas (RRA, RRA*).

10. A radio communications system for connection control during calls from and to radio subscribers, comprising:
-
communication terminals; a radio subsystem via which said communications terminals which allow access by the radio subscribers can be connected in an associated radio area; a switching center for switching through connections; a radio transmission unit which is arranged between said radio subsystem and said switching center and via which said connections are routed, said routing being implemented so that when a call within a radio area between radio subscribers within a same radio area, or when a call between radio subscribers in different radio areas is made, signaling connections, and not traffic channel connections, are switched through from said radio transmission unit to said switching center, and said routing being implemented so that traffic channel connections are switched by said radio transmission unit between a first radio subsystem and a second radio subsystem when a call is made between radio subscribes in different radio areas. - View Dependent Claims (11, 12, 13, 14)
