ATM switching architecture for a wireless telecommunications network
First Claim
1. An ATM switching architecture for a wireless telecommunications network, comprising:
- a plurality of ports for a plurality of access points of a wireless communication system;
means for performing switching operations and mobility control including a first unit for performing a mobility related switching and a second unit for performing a VP/VC connection related switching, wherein said first unit switches a virtual path containing all virtual channels of a mobile terminal from a first port of said first unit associated with a first access point, to a second port of said first unit connected to a first port of said second unit, and wherein said second unit distributes said all virtual channels of said mobile terminal from said first port of said second unit to different destination ports in said second unit.

Abstract
An ATM switching architecture for a wireless telecommunications network includes two separate units having different functionality. The first unit performs mobility control, wherein a virtual path which contains all virtual channels of a mobile terminal is switched from a first port associated with a first access point, to a second port connected to a first port of the second unit. The second unit performs a switching operation, wherein the virtual channels of the mobile terminal are distributed from the first port of the second unit to different destination ports of the second unit. In one embodiment, the two units may be dedicated hardware components, and in another embodiment, one single hardware component is functionally separated into two separate units connected by a loopback link.

12. A method for switching ATM signals in a wireless telecommunications network, comprising:
-
providing a plurality of ports for a plurality of access points of a communications system;
performing mobility related switching of a virtual path containing all virtual channels of a mobile terminal from a first port of a first switching unit associated with a first access point to a second port of the first switching unit;
providing said all virtual channels from the second port of the first switching unit to a first port of a second switching unit;
distributing each of said all virtual channels from the first port of the second switching unit to an appropriate one of a plurality of destination ports in the second unit.
