Patent ID: 8194671

Claim:
A method in a wireless cellular communications system, comprising a user equipment (UE), a hierarchy of nodes between the UE and an external network which the UE wishes to communicate with, said hierarchy comprising at least a first and a second node, a plurality of connections between the UE and the external network via data channels between said first and second nodes, and a plurality of data containers which contain data regarding the data channels, and in which system a connection from the plurality of connections between the UE and the external network is inactivated whilst the corresponding data container is preserved, and in which system the inactivated connection from the plurality of connections is reactivated by a request from the external network to said second node, the method comprising the steps: the second node sending a Paging message to the UE via a Radio Network Controller (RNC), wherein the UE establishes a Radio Resource Control (RRC) connection and sends a Service Request to the second node; the RNC node sending a Radio Access Bearer Assignment message to the second node; the second node sending a downlink Protocol Data Unit packet to activate the Resource Access Bearer associated with the inactivated connection from the plurality of connections; and wherein the inactivated connection from the plurality of connections is reactivated by a request from the external network.
