Abstract: A method of handing off an ongoing wireless telecommunication session with a mobile station when the mobile station is engaging in the ongoing communication session via a first access system, and then registers in a second access system, is provided. When communicating with the first access system the mobile station communicates with a first access node according to a first protocol. When communicating with the second access system the mobile station communicates with a second access node according to a second protocol, which is a different protocol than the first protocol. After registration of the mobile station in the second access system, the ongoing communication session is carried between the mobile station and the second access node according to the second protocol over the first protocol. More specifically, the ongoing communication session is carried between the mobile station and the second access node using the first protocol encapsulated in the headers of the second protocol.

Abstract: A location determination method uses location data items that originate at known locations and are passed to, and diffused between, entities by short-range communication. Each location data item received by an entity specifies its originating location and a time value dependent on when it originated from that location. An entity derives its location from received location data items by effecting a weighted combination of the known locations specified in the received location data items, the weighting of the known location specified in each received location data item being dependent on the associated time value.

Abstract: An inter system handovers in a mobile telecommunication system is performed when a dual mode user equipment (UE) covered by both GSM/GPRS network and UMTS network connects a dedicated channel and sets up a call in a BSS region where the GSM/GPRS provides coverage, and then moves to a UTRAN (UMTS Terrestrial Radio Access Network) where the UMTS provides coverage, wherein the method includes the steps of: if the dual mode UE receives an inter system handover command, i.e.

Abstract: A system for determining the location of a device in a wireless communication network includes at least one antenna for transmitting signals in a wireless communication network. A monitoring unit, located proximate to the at least one antenna, is operable for receiving, as a first input, signals transmitted by the antenna and signals from a device in the network and for receiving, as a second input, signals to be transmitted by the antenna. The monitoring unit includes at least one cancellation stage for modifying the second input and combining the modified second input with the first input to reduce the effect of the transmitted antenna signals on the monitoring unit first input.

Abstract: A communication system includes a base station and a plurality of remote stations wirelessly communicating with the base station. The base station determines a respective RF quality for each remote station. In response to a request for RF resources from a given remote station, the base station determines whether admission of the given remote station would exceed an RF power budget threshold. If the RF power budget threshold would not be exceeded, the RF quality is compared to a first quality threshold to determine whether to allocate the requested RF resource to the given remote station. Otherwise, the RF quality is compared to a second quality threshold more stringent than the first quality threshold to determine whether to allocate the RF resource to the given remote station. The base station may further determine whether to allocate requested RF resources on the basis of a priority of the requested resources.
