摘要： For reducing IP level signaling and radio resource load during the attachment or update, e.g. L3 or IP attachment/update, of a mobile unit to a cellular wireles s communication network, preferably an IPv6 based network, wherein access network elements and routing network elements are provided, an identification element is transmitted from the mobile unit to one of the access network elements. The identification element indicates a current attachment of the mobile unit to one of the routing network elements. The transmitted identification element is checked so as to determine whether the access network element is provided with a connection to the one routing network element. Furthermore, it is checked whether a network status still allows the usage of this routing network element by the mobile unit. If both of these criteria are fulfilled, the attachment or update procedure between the mobile unit and the access network element is completed while the attachment of the mobile unit to the routing network element is retained unaffected. This process is executable when the mobile unit moves from one cell area to another cell area, or when a network status concerning the attachment of the mobile unit has changed, or when a predetermined period of time is expired while the mobile unit remains in the same cell area.

摘要： A controller for a communications system comprises an input and an output for communicating with nodes connected to the communications system. The controller is provided with a processor for determining presence of an address translator entity between a first node and a second node. The controller is further configured for generating an indication of the presence of the translator entity for sending to another node.

摘要： Apparatus, and an associated method, for a 3G, cellular communication system having an access network (16) and a core network (14). The access network (16) is operable pursuant to the cdma2000 the operational specification, and the core network (14) is operable pursuant to the 3GPP architecture using GPRS. A wireless gateway (18) that provides an interworking functionality is provided to permit to the access network to utilize GPRS as a transport layer through which to transport packet-formatted data, thereby to effectuate, for example, multimedia applications over IP.

摘要： The invention provides in one aspect thereof a multi-carrier (MC) wireless network with a method to allocate a carrier to an idle mobile station. The method includes, responsive to the mobile station registering with the MC wireless network, selecting one of N available carriers to be assigned to the idle mobile station based on at least one criterion, and subsequently paging the idle mobile station on the assigned one of the N available carriers. The invention further provides, in other aspects thereof, a MC wireless network that operates in accordance with the methods, and a mobile station having a transceiver and a controller that is operable with the MC wireless network, where the controller is responsive to an order message received from the MC wireless network via the transceiver, when in an idle state, to transition to a carrier identified by the order message and to monitor the paging message in the assigned carrier. The controller further executes an idle handoff to one of another carrier, in a target cell, identified by a subsequent order message received over the assigned carrier, or to the same carrier in the target cell.
