A method for resetting a high speed medium access control entity includes: receiving a reset instruction sent from a radio network controller, where the reset instruction includes reset indication information of a cell; and determining a to-be-reset cell according to the reset indication information, and resetting a high speed medium access control entity for the to-be-reset cell.

A radio communication system, that includes a source base station; a target base station; and a mobile station for receiving either first sequence number or second sequence number, or both of the first and second sequence numbers from the target base station, whereby the first sequence number is transferred from the source base station to the target base station and the second sequence number is added to PDCP (Packet Data Convergence Protocol) SDU (Service Data Unit) which is transferred from the source base station to the target base station.

A method, apparatus and computer program product are provided herein for enabling a D2D bearer to stay alive even in an instance in which a D2D connection is lost. In some example embodiments, a method is provided that comprises detecting a condition that indicates that a device-to-device bearer is to be terminated. The method of this embodiment may also include modifying a cellular bearer protocol data unit header, such that the cellular bearer protocol data unit header indicates that a cellular bearer service data unit is a device-to-device protocol data unit. The method of this embodiment may also include causing one or more device-to-device protocol data units to be encapsulated within one or more cellular bearer protocol data units, such that the one or more device-to-device protocol data units are transmitted via a cellular bearer.

A method and intermediate network node provide a service requested by a mobile terminal in a wireless communications network. The intermediate network node has a processing unit and a memory containing instructions executable by the processing unit. The intermediate network node receives a first request for a service from the mobile terminal, and receives application software configured to be executed at the intermediate network node to provide the mobile terminal with at least part of the requested service. The intermediate network node provides the mobile terminal with the at least part of the requested service. A subsequent request related to the service of the mobile terminal terminates at the intermediate network node, and provides the mobile terminal with at least part of the service requested in the subsequent request on behalf of a provider of the service.
