The wireless device (110) attempts random access to a base station (105) using a random access preamble (120) selected from the selected group (135).

Abstract: This disclosure provides for an enhancement to a transport layer switch and, in particular the management of end points. In this approach, a memory space, such as a large logical ring buffer, is shared by incumbent connections to facilitate a space multiplexing end point management scheme. Preferably, memory allocation in the memory space is done packet-by-packet dynamically. Because the memory space is shared by all admitted connections, packets belonging to the same connection are not necessarily located physically consecutive to each other. A packet indexing mechanism that implements a set of pointers ensures that consecutiveness for packets on the same connection is maintained. This approach to end point multiplexing provides significant benefits by improving resource utilization, and enabling a higher number of connections to be served.

Abstract: In one embodiment, a network node automatically cycles among packet traffic flows and subjects the currently selected packet flows to varying drop probabilities in a packet network, such as, but not limited to in response to congestion in a device or network. Packets of a currently selected packet traffic flow are subjected to a drop or forward decision with a higher drop probability than packets of a currently non-selected flow. By cycling through all of these packet traffic flows, all of these packet flows are subjected to the drop or forward decision in the long term approximately uniformly, thus providing fairness to all packet traffic flows. In the short term, packets of a currently selected flow are targeted for possible dropping with a higher drop probability providing unfairness to the currently selected flows over the non-selected flows.

The solution can operate with UEs that operate in either Single Registration (SR) mode embodiments or Dual Registration (DR) mode embodiments. Depending on the embodiment, the UE can perform a handover or redirection to the legacy system (such as E-UTRAN).
