Abstract: In one embodiment, a load balancer receives a message from a tunnel termination gateway (TTG) associated with a mobile device. The load balancer may receive messages from a plurality of TTGs. A gateway node in a plurality of gateway nodes in which to send the message is determined.

The load balancer ensures that the assigned NSAPI is not currently in use at the gateway node. Thus, no overlapping of NSAPIs may occur even though the load balancer is processing messages from multiple TTGs for multiple gateway nodes.

Abstract: Apparatus and methods for efficient queuing and dequeuing using segmented output buffers comprising sub-buffers and priority queues. Output buffers are monitored for empty sub-buffers. When a newly empty sub-buffer is discovered, a refill request is enqueued in a ranked priority queue wherein the rank of the destination priority queue is based on the number of empty-sub-buffers in the requesting output buffer. All high priority refill requests are dequeued before lower priority refill requests, thereby reducing the possibility of starvation. Optionally, by using simple dequeuing criteria, such as a FIFO discipline, instead of complex algorithms designed to improve fairness, system resources may be conserved thereby improving system throughput.

Abstract: Systems and methods are provided wherein an incoming plain old telephone systems (PSTN) signal is input into a home network conversion interface. The home network conversion interface first determines the data type of the incoming signal. Next, the home network conversion interface creates a routing sequence of the incoming signal based on the determined data type.

Should the home network conversion interface lose electrical power, a drop contactor routes the incoming signal directly to an analog device without creating a routing sequence or performing an 802.X conversion.

Abstract: A method and apparatus for selecting a preferred signal from homogenous streams of a subscriber call in an analog or mixed mode wireless communication network. The method and apparatus have particular significance to un-decoded analog radio packets which require digital signal processing to decode at least their signaling information. The method allocates at least one stream with the best signal qualities to real-time full-decoding in a DSP, and allocates lower quality streams to non-real time burst decoding in the same or another DSP. As signaling quality changes in the homogenous streams, the full-decoding can be re-allocated to a now higher quality stream. Burst decoding lower quality streams allows for more efficient use of DSP processing power and allows more streams to be processed without significant affect on audio content or quality.

If it can be accommodated, a network entry sequence is run in order for the terminal to communicate with the base station since communications with the base station is available.
