Abstract:
A wireless communication system (20) allows communications between a mobile station (22) and a wireless network (24) over combined physical traffic channels (44, 46). In a disclosed example, a mobile station (22) has multiple wireless access terminals (40, 42) for transmitting different portions of a communication over multiple physical traffic channels (44, 46). In a disclosed example, each wireless access terminal (40, 42) utilizes one of the channels (44, 46). A known multilink PPP protocol facilitates splitting a communication into portions to be communicated over the combined physical traffic channels (44, 46) and then recombined at the mobile station (22) or an appropriate portion of the network (24). With a disclosed example, the achievable throughput using combined physical traffic channels (44, 46) approaches the aggregate or sum of the individual channel throughput capacities.
Abstract:
During periods of silence, communication links between elements of a communication system are used more efficiently by sending messages instructing an element to generate comfort noise rather than sending messages containing comfort noise. A message instructing an element to generate comfort noise is smaller than a message containing comfort noise. As a result, the bandwidth of links between communication system elements is used more efficiently by sending messages or commands to generate comfort noise rather than a message containing comfort noise.
Abstract:
The present invention provides a method of wireless communication with at least one mobile unit. The method includes providing information indicative of at least one channel and at least one channel capability associated with said at least one channel.
Abstract:
A method for determining rise over thermal for a base station in a wireless communications system is provided. The method comprises receiving a first and second diversity signal, measuring the signal strength of the first and second diversity signals, and estimating the noise floor for the first and second diversity signals. The signal strength rise is determined for the first and second diversity signals based on the measured signal strength and estimated noise floor of the first and second diversity signals respectively. The rise over thermal is then determined based on the determined signal strength rise of the first and second diversity signals.
Abstract:
In the method, an overload control threshold is adjusted based on at least one outage metric (S10,S16) and an overload control history (S12). Overload control is performed based on the overload control threshold.

Abstract:
A wireless communication system (20) includes a wireless network (22) that communicates with a plurality of base stations (24) over a backhaul network (26). A disclosed example includes monitoring an amount of control traffic on the backhaul network (26) and dynamically and automatically adjusting an allocation of the backhaul resource for handling the control traffic. A disclosed example automatically allocates a remaining amount of the backhaul resource for handling bearer traffic.
Abstract:
Communication links between elements of a communication system are used more efficiently by transmitting comfort noise messages discontinuously. When periods of silence or messages containing comfort noise are detected, a single comfort noise message is transmitted rather than a long sequence of comfort noise messages. As a result, the bandwidth of communication links is not wasted by sending large numbers of messages containing comfort noise. The comfort noise is reconstructed at a communication element receiving the reduced number of messages by generating new comfort noise messages to replace the missing comfort noise messages. One method of regenerating comfort noise messages is to simply repeat the most recently received comfort noise message until a new comfort noise message is received.
