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.

Signal prioritization in a communications system

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.

Packet traffic channel reassignment

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.

Layer 2 protocol in a cellular communication system

A communications system in which information is transmitted in a plurality of time slots grouped into a plurality of superframes which are, in turn, grouped into a plurality of paging frames. A remote station receives paging messages once in each paging frame.

Method for communicating in a wireless communication system

A method and apparatus for performing reconfiguration of a cellular network is provided. Cell parameters of affected mobile switching centers in the network are copied to a database, and the copied parameters are stored. A set of proposed changes to the stored parameters are prepared and the consistency of the prepared set of proposed changes is verified. Any necessary alterations to the set of proposed changes responsive to the verification are made and the verified set of proposed changes are copied to the affected mobile switching centers. The verified set of proposed changes are then introduced into the network. Additionally, at all times, an up-to-date image of all the cell parameters in all the mobile switching centers in the network is maintained in a system parameter database.
