An unlicensed wireless service (126) is adapted to generate the interface protocols of a licensed wireless service (106) to provide transparent transition of communication sessions between a licensed wireless service and an unlicensed wireless service. In one embodiment, a mobile station (102) includes level 1, level 2, and level 3 protocols for licensed wireless service and an unlicensed wireless service. An indoor base station (128) and indoor network controller provide protocol conversion for the unlicensed wireless service into a standard base station (108) controller interface of the licensed wireless service.

Apparatus and method for extending the coverage area of a licensed wireless communication system using an unlicensed wireless communication system

Methods to create a cellular-like communication system, such as a Wireless Private Branch Exchange (WPBX) (123, 124), which includes mobile devices (121, 123) such as a standard cordless phone (handsets), particularly, mobile devices utilizing the Bluetooth short-range wireless communication protocol. The methods provide seamless and reliable handoff of sessions between Base Stations while the mobile device is moving between picocells, by implementing a high-level of synchronization between the Base Stations and the Switch (129). Base Stations of picocells having small coverage areas communicate with the handsets. The communication protocol is divided into a low-level protocol (280, 281) performed by the Base Stations and a high-level protocol (283, 284) performed by the Switch connected to all the Base Stations. The methods support mobile computing or telephony devices and communication protocols, which are not specified to handle handoffs of sessions while moving between Base Stations coverage areas in a data, voice or telephony wireless network.

Method and devices for use in a centralized wireless network are provided. The centralized wireless network employs a wireless communication protocol to communicate with various devices throughout the network. In addition to communication, the protocol may be used to control and monitor various aspects of the devices throughout the network.

Centralized wireless network for multi-room large properties

A method and system for locating an unlicensed mobile access (UMA) subscriber. The method enables a user of a mobile station comprising a hand-set or the like that supports voice and data access via both licensed and unlicensed radio spectrums to be located. Accordingly, services requiring location information, such as 911 services, may be accessed when operating the mobile station under both UMA and licensed wireless network (e.g., cellular) sessions.

Method and system for determining the location of an unlicensed mobile access subscriber

Methods and messages for performing registration of mobile stations (MS) in an unlicensed mobile access network (UMAN). URR (UMA radio resource) registration messages are exchanged between an MS and a UMA network controller (UNC) operating in the UMAN to register the MS. The MS may access the UMAN via a wireless access point (AP) that is communicatively coupled to the UNC via an IP network. The URR registration messages are sent between the MS and the UNC using an Up interface comprising a set of layered protocols over an underlying IP transport.

In order to design a cellular cordless telecommunications system which makes it possible to implement a large number of performance features, for example synchronization, roaming, handover, internal links, hold, check-back, transfer etc. in the cellular cordless telecommunications system without any additional wire link between the cordless base stations in the cellular cordless telecommunications system, the cordless base stations are connected to an S0 bus (i.e., a basic access line for a multi-device configured system).

Cellular cordless telecommunications system

In order to design a cellular cordless telecommunication system such that a plurality of its performance features, e.g. synchronizing, roaming, handover, internal connections, holding, enquiries, transfer, etc., can be carried out without an additional wire connection between the cordless base stations of the cellular cordless telecommunication system, the cordless base stations are connected to an SO-bus.

The invention relates to a method and device for the wireless transmission of voice data between at least two terminals, whereby the voice data is transmitted in data packets in predefined time frames with multiple redundancies and in time intervals at different frequencies. The invention is characterised in that the transmission takes place at different frequencies, at least with regard to a pair of redundant data records.
