A satellite routing protocol is provided in a packet switched mesh network environment (i.e., where user traffic is not routed through a single or central node) wherein all IP planning and routing in the global WAN network is provided through a central database management element and routing information is disseminated separately from the communication traffic via a bandwidth constricted control channel in communication with each node but typically set aside for other purposes (such as conventional DAMA control). Two specific approaches include a link state approach and a distance vector approach. The specific embodiments disclosed for the Satellite Routing Protocol (SRP) system according to the invention allows both fixed and mobile networks to connect directly to each other or to a gateway network via either a terrestrial LAN or a Demand Assigned Multiple Access (DAMA) WAN where there are links that are dynamically assignable.

Satellite routing protocol with dynamic IP addressing

A method for reducing power consumption in a cellular telephone that receives multiple copies of a message comprises the steps of receiving a copy of a message block having a plurality of data bits; generating soft output signals representative of all data bits in the message block; computing a block quality metric indicative of the reliability of the message block; comparing the block quality metric with a first threshold; if the block quality metric bears a predetermined relation to the first threshold, combining the copy of the message block with a previously accepted message block to obtain a combined message block; determining the number of erasures in the combined message block; comparing the number of erasures with a second threshold; if the number of erasures is below the second threshold, decoding the combined message block to determine the number of errors in the combined message block; comparing the number of errors with a third threshold and, if the number of errors is below the third threshold, accepting the combined message block; and generating timing signals instructing the receiving device to interrupt reception of further copies of the message block for a specified period of time.
