Abstract

A system is provided for making connections in a telecommunications system that includes a network for transporting communications between selected subscriber connections, and a wireless network for coupling connections to the network. The network and wireless network are interfaced with a traffic management element and at least one radio controller shared by connections, with the traffic management element and the radio controller forming a single integrated network element. Connections are routed from the wireless network to the network via the single integrated network element.

Claims

1. A method of making connections in a telecommunications system that includes a network for transporting communications between selected subscriber connections, and a wireless network for coupling connections to said network, said method comprising

interfacing said network and said wireless network with a traffic management element and at least one radio controller shared by connections, said traffic management element and said radio controller forming a single integrated network element,

routing connections from said wireless network to said network via said single integrated network element, and

conveying information relating to the status of said wireless network to said traffic management element to permit evaluation of performance changes in said wireless network and effecting corresponding adjustments of the transmission rate between said network and said wireless network.

2. The method of claim 1 wherein said adjustments are effected to avoid losses in said communications transported between said network and said wireless network.

3. The method of claim 1 which includes buffering traffic before transporting it to said wireless network when the transmission speed in said wireless network is reduced.
