The present invention provides for a method and related system and communication terminal devices, for assigning a radio resource allocation mode to a mobile radio communications device for device-to-device communication within a wireless communication network environment, the method including the step of identifying at the mobile radio communications device an initial radio resource allocation mode and further including the step of signalling from the network to the mobile radio communications device configuration data relating to an authorized radio resource allocation mode to be employed for the device-to-device communication and defining at least one operation requirement of the mobile radio communications device when employing the said authorized mode.

Device-to-device radio resource management

A communications system is provided. A network device controls the setting up of a device to device communication link, as sent between a device in the core network and the base station(s) servicing the relevant mobile devices, including disclosure of the common security information for two mobile devices to communicate securely over the direct device to device communications link.

Core network, user equipment, and communication control method for device to device communication

The present invention provides for a method of configuring a physical channel, such as a physical control channel, for device-to-device communication between mobile terminal devices within a cellular communications network environment and comprising a step of locating a device-to-device control channel within a cellular uplink signaling spectrum, and applying a frequency offset parameter to determine separation of the device-to-device control channel from a cellular uplink control channel, and to related terminal devices and computer program products.

Channel configuration in device-to-device communications

A communication system is described in which an MBMS service is provided by unicast or broadcast/multicast communication in dependence on whether the number of mobile communication devices indicating an interest in receiving the service is below or above a broadcast threshold. An improved procedure for counting the number of mobile communication devices interested in receiving the MBMS service is also disclosed.

Communication system

A method of controlling switching between dedicated radio resources of a mobile radio communications network includes providing, using a first radio bearer (RB), a first service to a mobile radio communications device within the network, receiving, from the mobile radio communications device, a message indicating a desired change of service and sending a Radio Resource Control (RRC) message to the mobile radio communications device, the RRC message serving to initiate both release of the first radio bearer, and set-up of a second radio bearer to provide a second service to the mobile radio communications device, the second service being different from the first service.

Dedicated radio resource control

The present invention provides for a mobile radio communications device, and related method of operation, arranged for closed subscriber group selection and for the storage of closed subscriber group information in the device, the stored information including information configured as a whitelist of closed subscriber group identities delivered between non-access-stratum layer and access-stratum layer within the device, and the device being further arranged to remove a previous user-selected closed subscriber group identity from the whitelist responsive to the device connecting to a cell is different from that identified by the previous user-selected closed subscriber group identity, and which different cell can comprise for example a non-CSG cell.

Mobile radio communications device for closed subscriber group management

The present invention provides for a method of configuring a physical channel, such as a physical control channel, for device-to-device communication between mobile terminal devices within a cellular communications network environment and comprising a step of locating a device-to-device control channel within a cellular uplink signalling spectrum, and applying a frequency offset parameter to determine separation of the device-to-device control channel from a cellular uplink control channel, and to related terminal devices and computer program products.

A mobile device () configured to provide relay capabilities in a communications system () by communicating network-level mobile device relaying capabilities and radio-level mobile device relaying capabilities from the mobile device () to a communications node () of the communications system () so that the mobile device () can relay communications between the communications node () and another mobile device (). User subscription information related to relaying is also disclosed.

Mobile communications device and system

The present invention provides for a method of controlling switching between dedicated radio resources of the mobile radio communications network including sending an RRC massage to UE within the network requesting both RB release and RB set-up at the user equipment, such that only a single message is required for reconfiguration sufficient to allow switching between the RB resources which, in one example, can comprise different channels of a Mobile TV service.

The invention relates to a method for relaying a communication in a network, wherein a user equipment (UER) relays a communication between a network node entity (eNB) and a target entity (UET), the method including the steps, generating a logical channel at least between the user equipment relay (UER) and the target entity (UET), and assigning at least one identifier (LC_ID_R) to said logical channel, and upon reception from the network node entity (eNB), at the user equipment relay (UER), of data received with said identifier (LC_ID_R), the user equipment relay (UER) forwards the received data to the target entity (UET).

Optimized user equipment supporting relay communication, and related method

The invention provides for a method of easing congestion in a mobile radio communications network including the step of applying access restriction at a mobile radio communications user terminal device towards the network and on the basis of bearer characteristics such as new or ongoing bearer, bearer quality of service, bearer type and or bearer class, and the access restrictions being controlled by the network e.g. the Radio Access Network such as via an eNodeB or the Core Network.
