Abstract:
A method, including receiving at a first communication device from a first network information for assisting device-to-device transmissions between a group of communication devices including said first communication device; thereafter detecting at said first communication device loss of possibility to continue receiving assistance for said device-to-device transmissions from said first network; and deciding at said first communication device whether to continue with said device-to-device transmissions with assistance from a second network or without assistance from a second network.
Abstract:
Apparatuses and methods for communication are provided. An example solution may include determining a need for requesting channel resources from other user terminals of a group of user terminals for proximity-based communications within the group of user terminals; transmitting a channel resource request to at least one user terminal of the group of user terminals; receiving one or more responses to the request, the one or more responses coming from other user terminals of the group and including information on available channel resources; selecting the channel resources to utilise and starting transmission utilising the selected channel resources.
Abstract:
A technique is provided for receiving, by a MS from a BS a failure notification message indicating a failure of a BS-core network interface, sending, from the MS to the BS, a security agent (SA) notification including a MSID identifying the MS, a service profile identifying one or more services, and one or more user group IDs that identify one or more user groups of which the MS is a member, and receiving, by the MS from the BS, a SA configuration message including a service identification identifying at least one of the one or more services, one or more user group IDs identifying one or more user groups for which the MS has been configured as a security agent to perform the identified service, and a BS access key to allow one or more other MSs to access or establish a connection with the BS.
Abstract:
Methods, apparatuses, and computer program products for network assisted ProSe discovery management are provided. One method includes establishing, by a network element, a discovery context of a user equipment, and transmitting a discovery context establishment request comprising beacon information on at least one other user that a user of the user equipment is interested in discovering.
Abstract:
A method for device-to-device communication includes receiving, in a D2D-capable user terminal from a network apparatus, measurement configuration information regarding a D2D discovery resource usage status. The user terminal performs, based on the received measurement configuration information, a corresponding measurement to determine the usage status of D2D discovery resources. The user terminal transmits, to the network apparatus, a report on the measurement performed in the user terminal, the report indicating the usage status of D2D discovery resources, in order the network apparatus to be able to adjust D2D discovery resource allocation based on the report.
Abstract:
It is provided a method, including: monitoring if a first cluster head of a first cluster of first communication devices has disappeared, wherein an apparatus performing the method has access to the first cluster enabling a device-to-device communication of the apparatus with at least one of the first communication devices; and, if it is monitored that the first cluster head has disappeared: detecting a second cluster head of a second cluster of second communication devices, wherein the second cluster head is different from the first cluster head, and the second cluster enables the device-to-device communication between at least two of the second communication devices; and requesting an access to the second cluster for the device-to-device communication.
Abstract:
A method and apparatus can be configured to update status information on channel resources. The channel resources are configured for device-to-device communication by a cluster-wise manner. The method can also include transmitting the status information by using broadcasting resources.
Abstract:
Lawful interception and security for proximity service There are provided measures for lawful interception and security for proximity service. Such measures could include performing control in relation to a connection of a proximity service between at least two devices, determining at least one lawful interception and security agent located within the proximity service range of at least one device to be intercepted among the at least two devices, and controlling the determined at least one lawful interception and security agent to perform an operation relating to lawful interception and/or security in relation to the connection of the proximity service.
Abstract:
There is provided a method, including requesting, by a network element of a macro cell network infrastructure, a local cell access point operating within the macro cell to either activate or deactivate a local cell control plane with respect to active user equipment of the local cell, wherein the local cell access point continues to provide a user plane to the active user equipment; and receiving a response to the request.
