  • Signal prioritization in a communications system
    Patent number: 7941175
    Abstract: A method, system, and apparatus enables lower priority (e.g., access response) messages to be transmitted instead of higher priority (e.g., paging) messages when the lower priority messages become too backlogged in an environment in which the two types of messages share a given capacity. In other words, when an overload situation is detected, the shared capacity is regulated by ensuring that the lower priority messages have at least some bandwidth. For example, if (i) the lower priority messages reach a predetermined number or (ii) a particular lower priority message has been waiting a predetermined period of time, then at least a portion of the higher priority messages are diverted (e.g., delayed or deleted). In one embodiment, the higher priority messages that are initially diverted are a lowest priority subset of the higher priority messages. In another embodiment, a highest priority subset of the lower priority messages are transmitted first as capacity is made available.

  • Packet traffic channel reassignment
    Patent number: 6597680
    Abstract: The present invention provides a method and system for quickly deallocating packet traffic channels. According to exemplary embodiments of the present invention, the capability of performing point-to-multipoint communications is provided on the PTCH by defining a multicast address that all mobiles read. Through the use of a multicast address, a plurality of mobile stations can simultaneously be notified of the termination of PTCH services. As a result, the network can reallocate PTCH resources in a minimum amount of time.

  • Layer 2 protocol in a cellular communication system
    Patent number: 6175557
    Abstract: A method for transmitting messages using an efficient communications link protocol over an air interface of a cellular communications system is disclosed. A frame in the protocol is divided into a plurality of sections including a header section and a data section. The header section contains a field which indicates what type of information is contained in the frame.
