A communication system comprising a local network node (LNN) is described for connecting with a user terminal in a 3G network. The LNN provides a local user-controlled access point for the network that may be installed in the home or office by-passing connection through network Node Bs. If the User passes outside the coverage area provided by the LNN, then a handover between the LNN and an appropriate Node B preferably takes place so that the User's connection to the 3G network is substantially unaffected. The LNN is arranged to provide protocol conversion between the 3G control messages received from the UE to the equivalent SIP/SDP messages required for maintenance of connections in Internet Protocol based networks, such as the Release 5 architecture.

Local network node

In general, media data is stored in a storage medium of a mobile base station. The mobile base station transmits the media data from the mobile base station to a handheld device through a packet data protocol context.

Personal access point media server

The invention relates to a method and system of setting transmitter power levels, particularly in a Local Network Node transmitter, providing a pico cell for private use. A User Equipment (UE) is used to make measurements of the transmission link properties, such as downlink power and round trip time. Based on the measurements made at one or a plurality of locations, the power of the Local Network Node can be determined such that interference is minimized with any overlying cells of a macro-network. Call handovers between the UE and the cell of a macro network can also be arranged based on properties measure by the UE.

Method and system of setting transmitter power levels

A method for configuring a network is described, the method comprising: receiving, from a first radio node in the network, network information associated with one or more second radio nodes in the network; generating a network relation table, the network relation table comprising network information associated with the first radio node and the one or more second radio nodes; and performing a handoff to a third radio node in the network using the network relation table.

Mobility in a wireless enterprise network

In general, a method performed on a portable access terminal operating in an active mode includes detecting a presence of a personal base station. An encoded identification message transmitted from the personal base station is received, and the encoded identification message includes a unique identifier associated with the personal base station. The encoded identification message is decoded to extract the unique identifier, and the unique identifier is transmitted to a source network entity.

Identifying hand-over targets in lightly coordinated networks

In general, a method performed on a personal base station includes transmitting a first pilot signal to a portable access terminal operating in an idle mode in a macrocell that uses a first carrier frequency. The first pilot signal is transmitted in the first carrier frequency to allow the portable access terminal to temporarily connect to the first pilot signal. A second pilot signal is transmitted in a second frequency that is different than the first frequency. The portable access terminal is dispelled from the first pilot signal, and the portable access terminal is allowed to connect to the second pilot signal.

Multi-carrier system selection

A transmitter is provided having transmission methods that minimize the power needed to ensure reliable reception in a coverage area. In one aspect, data that requires re-transmission as acknowledged mode data is re-transmitted when the power level of the transmission link is higher than a pre-determined level set for reliable reception. The data rate of the re-transmitted data is set according to the difference in the actual power and the pre-determined level. In a second aspect, two transmitting antennae are used to transmit the same signals with a frequency off-set. The frequency off-set can be used to determine the phase of the signals being received at the receiver, so that a phase off-set can be introduced to optimise the effect of interference at the receiver.

Signal transmission method from a local network node

Power control in a local network node (LNN)

In general, a method includes monitoring, by a personal access point, an amount of backhaul bandwidth available for multimedia and signaling communications by measuring a level of latency associated with existing multimedia and signaling communications.
