Abstract: Devices, systems, and methods for gathering, calculating and sending positioning information at a user device to one or more networks may be disclosed. In a first implementation the user device transforms pseudorange information relating to terrestrial beacons into GNSS pseudorange information. In a second implementation, the user device sends position information using GNSS information elements. In a third implementation, the user device sends position information using non-GNSS information elements.

Abstract: A method is disclosed for operating a user terminal, such as a cellular radiotelephone, of a type that is bidirectionally coupled to a network through an RF interface. The method includes a first step of storing at least one message in a memory accessible by the mobile station. A second step transmits a Teleservice origination (e.g., a SMS origination) request from the mobile station to the network using a reverse digital control channel. The request specifies that a reverse digital traffic channel be assigned to the mobile station. A next step, executed in response to being assigned to a reverse digital traffic channel, transmits the at least one stored message to a SMS center that is coupled to the network, the at least one stored message being transmitted over the assigned reverse digital traffic channel.

Abstract: A long term average and a short term value of the strength of a received signal is used to determine a trigger condition in a mobile communications system to perform such functions as control channel or traffic channel reselect. The long term average removes the effects of short term fades in the short term signal that otherwise may cause a premature trigger decision. The short term value offsets historical bias that may be built into long term average. The actual trigger is only realized when both the long term average and the short term value exceed predetermined thresholds in a positive or negative direction.

Abstract: This invention teaches a method of operating a cellular communication system, and includes the steps of: (a) allocating mobile stations into groups as a function of their ability to support a smart antenna transmission from a base station; and subsequently allocating frequency channels to the groups of mobile stations in accordance with one of a static allocation and a dynamic channel allocation.

Abstract: A micro-cellular radio communications system (microsystem) is arranged to re-use radio frequency channels which are assigned for use in a cellular radio system (macrosystem) in the same vicinity. The microsystem maintains a list of each frequency channel which is in current use in any microcell of the microsystem. In each microcell of the microsystem a signal characteristic, for example received signal strength, of each frequency channel, is repeatedly measured when the channel is not in current use in any microcell of the microsystem, and the measurements are used to determine a long-term statistical preference for re-use of a favoured set of the frequency channels in that microcell. For each microcell, the frequency channels in the favoured set are given a short-term order for actual use in dependence upon frequent measurements of the signal characteristic for the microcell regardless of whether or not the channel is in current use in any other microcell of the microsystem.

Abstract: A mobile communications system accommodating both expanded spectrum (ES) mobiles and non-expanded spectrum (NES) mobiles incorporates a first set of (ES) channels and a second set of (NES) channels. A proportion of the channel requests from ES mobiles are allocated to a queue for NES channels. NES channels are allocated to these ES mobiles until no further NES resources are available. Further requests from ES mobiles in the NES channel queue are then met by allocating available ES channels. This provides an enhanced efficiency of utilisation of channel resources. Advantageously, a subset of NES channels is reserved for preferential use by NES mobiles to ensure fair allocation of channels between the two types of user, these channels being allocated to ES mobiles only if no other channels are currently available.
