A computer-implemented method for channel switching in a mesh network is described. In one embodiment, a beacon is sent. The beacon includes a channel change request in both proprietary and standard formats. The channel change request includes an instruction to change to a particular channel and a geo-timing synchronization function identifying when the change to the particular channel should occur. The geo-timing synchronization function is used to determine that the time has arrived to change to the particular channel. The particular channel is changed to synchronously with all other access points in the mesh network.

A method of implementing multiple radio access technologies, RATs, by a multi-RAT wireless communication network and a wireless communication apparatus. The multi-RAT wireless communication network transmits, to the wireless communication apparatus, a signal relating to a second RAT using a first RAT. The wireless communication apparatus uses a first radio communication module configured to support the first RAT to receive the signal, and activates a second radio communication module configured to support the second RAT from a power saving in order to perform a function. The first RAT generally has lower power consumption in use at the wireless communication apparatus than that of the second RAT.

A first base station is configured to be connected with a second base station via an X2 interface. The first base station includes: a controller containing at least one processor and at least one memory, and configured to execute processes of transmitting a message, which includes a first identifier, coverage state information, and a second identifier, to the second base station before modifying a coverage of the first cell, the first identifier identifying the first cell, the coverage state information indicating that a state of the coverage after modification of the coverage, the second identifier identifying a second cell for compensating at least part of the coverage of the first cell; and modifying the coverage of the first cell after transmitting the message.

By first determining whether network conditions make it possible and necessary to assist the network in supporting communication devices in comparatively poor radio coverage, and then periodically determining what type of assistance would best improve the overall network performance, a cellular telecommunications network is dynamically adapted to improve overall network performance without requiring the introduction of new network equipment. In one example, the dynamic activation of the radio coverage assistance serves to reduce problems associated with users at the cell edge, resulting in improvements in overall cell capacity.

A cellular telecommunications network architecture is described where certain UEs are configured to assist the network to improve coverage in regions of poor radio conditions. In certain embodiments, appropriate UEs are selected to act as a dynamic, out-of-band coverage extensions. Network performance can thereby be improved when serving users at the cell edge (or in other poor radio condition regions of a cell).

A handover procedure can be implemented using a codec-specific threshold as a triggering event for the handover procedure. A mobile device can initiate a communication session with a serving access point (AP). The mobile device can receive a codec established for the communication session, access a set of codec-specific thresholds stored in memory of the mobile device to determine a handover triggering threshold that is specific to the codec used for the communication session. The mobile device can measure a parameter of a radio signal from the serving AP, and when the measured parameter falls below the codec-specific threshold, a handover procedure can be initiated to transition the communication session to a target AP.
