A method and apparatus for performing cell reselection in a wireless communication system is provided. A user equipment (UE) in an idle mode camps on a second cell, and receives reselection information for dual connectivity, which indicates cell reselection to a first cell or cell reselection to a frequency of the first cell, from the second cell. If the UE supports dual connectivity, the UE performs cell reselection based on the received reselection information for dual connectivity.

Certain communication devices in a telecommunications network may be suitable for providing assistance in supporting other communication devices in comparatively poor radio coverage. The telecommunications network is dynamically adapted to improve overall network performance without requiring the introduction of new network equipment by determining how these communication devices are to be activated/deactivated and maintained. In one example, the dynamic activation/maintenance of the radio coverage assistance serves to reduce problems associated with users at the cell edge, resulting in improvements in overall cell capacity.

A Machine-to-machine (M2M) terminal (11) comprises a radio communication unit (111) and a controller (112). The radio communication unit (111) is configured to communicate with a base station (13). The controller (112) is configured to change at least one of a cell selection operation, a cell reselection operation, and a handover operation according to whether a specific coverage enhancement processing is required or according to whether the specific coverage enhancement processing is supported by at least one of a cell (13) in which the M2M terminal (11) camps on and a neighbouring cell (14) of the cell (13) which the M2M terminal (11) camps on. It is thus possible to provide an improved technique for allowing the M2M terminal that is supporting a special coverage enhancement processing for M2M terminals to camp on an appropriate cell.

The present disclosure provides an access control method and apparatus, and a network device. The method includes: performing grid partitioning on a target cell covered by a wireless access point, to obtain multiple grids; grouping, based on a neighboring cell of the target cell, grids that satisfy a preset condition in the multiple grids into one or more interference clusters; calculating an access offset of each of the interference clusters; and sending, to a user in each interference cluster, an access offset of a corresponding interference cluster, so that the user selects a cell based on the access offset of the corresponding interference cluster. Grids of a target cell are grouped into interference clusters according to signal to interference plus noise ratios, and an access offset is set for each interference cluster, to ensure service quality and improve user experience.

A system and method of controlling the Radio Access Technology selected by a vehicle telematics unit includes receiving a request to initiate a voice call from a vehicle occupant at the vehicle telematics unit; ending any existing data connection that is using a latest-technology RAT to communicate with a cell tower, wherein simultaneous voice and data (SVD) communications are not possible using the latest-technology RAT; ending the data connection with the cell tower using a latest-technology RAT; establishing the voice call via a cell tower using an older-technology RAT; detecting the end of the voice call; commanding the vehicle telematics unit to end use of the older-technology RAT in response; and establishing data communications with a cell tower via the latest-technology RAT.

Disclosed is a system and methods for creating and maintaining a virtual subnetwork of telecommunication base stations within a wider telecommunication network. In an LTE-based example, the subnetwork includes a connection aggregator that is coupled between the plurality of eNodeBs internal to the subnetwork and one or more MMEs in the outer network. The connection aggregator intercepts all control plane messages between the MMEs and the internal eNodeBs, remaps eNodeB identifiers, and transmits repackaged messages so that the outer network sees the entire subnetwork as a single “giant” eNodeB. The disclosed system and methods enables the operator of the virtual subnetwork to add and shut down eNodeBs as demand for connectivity fluctuates, and to do so such that all changes are unseen by the outer network.
