Abstract:
A wireless communication device (10) controls changing of a connection of the wireless communication device (10) to an access node (100) of the wire-less communication network between: a relay based connection to the access node (100), and either a direct connection to the access node (100) or another relay based connection to the access node (100). The relay based connection extends via a device-to-device communication link (30) between the wireless communication device (10) and a first further wireless communication device (40). The other relay based connection extends via another device-to-device communication link (30′) between the wireless communication device (10) and a second further wireless communication device (40′). Further, the wireless communication (10) sends an indication to the access node (100). The indication enables the access node (100) to identify an existing Packet Data Convergence Protocolcontext, which was utilized before changing the connection, and to continue utilizing the existing PDCP context after the changing of the connection.
