Abstract:
1. A method for relaying communications between a mobile device and a network access node, comprising: establishing a connection between a first relay node of a group of relay nodes and the network access node, the first relay node serving the mobile device; performing an intra-group handover of the mobile device from the first relay node to a second relay node of the group, the intra-group handover being controlled by a mobility management system internal to the group such that the mobile device remains connected to the network access node via one of the first and second relay nodes during the intra-group handover; and communicating control information between said relay nodes on an interface between relevant relay nodes in the group for the intra-group handover to maintain the relayed communications for the mobile device after the intra-group handover between the relay nodes.
