Abstract: In accordance with embodiments of the invention, Mobile IP binding information is used to deliver mobile terminating packets using layer-2 tunneling. When terminating packets destined for a mobile node are received by a home network for the mobile node, the Mobile IP binding is used to obtain the address of a foreign network to which the mobile node is attached. A Layer 2 Tunneling Protocol tunnel is created between the home network and the foreign network, and an outgoing L2TP call is made from the home network to the foreign network. A call is made from the foreign network to the mobile node, and a PPP session is established between the home network and the mobile node, via the Layer 2 Tunneling Protocol tunnel between the home network and the foreign network. After the PPP session is established the home network can optionally assign the mobile node a private IP address, and translate the home IP address labeling the terminating packets to the private IP address.

Abstract: An apparatus and method provide MAC logic enabling the use of two or more reverse link rate controls at the same time in one or more sectors of a radio base station. That enables the base station to control reverse link loading via reverse link rate control, while assigning mobile stations to the type of reverse link rate control best suited to their needs. For example, the base station MAC logic may implement both a common rate controller that generates per-sector rate control commands, and a dedicated rate controller that generates per-user rate control commands and assign mobile stations having relatively lax reverse link service needs to the common rate controller, while assigning mobile stations having more demanding reverse link service requirements to the dedicated rate control. More than two rate controls can be implemented, and exemplary choices include per-user, per-sector, per-group, and scheduled rate control in any combination.

Abstract: A telecommunications system has a protocol architecture over an interface between nodes of the telecommunications system, the protocol architecture including Internet Protocol as a protocol above a link layer protocol in a transport network layer. The protocol architecture can be used over one or more of several interfaces, including the interface between a radio access network and a core network [Iu Interface]; the interface between radio network controllers (RNCs) and the base stations (BSs) served thereby [Iub Interface]; and the interface between a Source RNC (SRNC) and a Drift RNC (DRNC) [Iur Interface]. A new XTP Protocol is proposed as another aspect of the invention, which is usable in a protocol stack for the Iu-PS (packet switched) implementation as well as over the Iu-CS, Iub, and Iur Interfaces.

Abstract: A method and apparatus for link supervision determines whether a link signal is present or absent by measuring received energy for that signal. If the measured energy for the signal does not meet a defined energy threshold according to defined evaluation criteria, such as a sufficiency metric, the signal is deemed absent. Applied to wireless communication networks, such supervision may be used to suspend or terminate transmission responsive to detecting the link signal's absence. In an exemplary embodiment for 1xEV-DV (cdma2000 Revision C) wireless networks, a mobile station selectively performs forward link supervision based on measuring the bit energy of power control bits received by the mobile on a dedicated power control sub-channel. If a fundicated channel is assigned to the mobile station, it may perform forward link supervision based on Frame Error Rate (FER) estimations for data received on the fundicated channel rather than the energy-based approach.

Abstract: Techniques are provided for sequencing user data packets (e.g., voice packets) segmented into plural AAL2 packets which are in turn carried over Internet Protocol (IP). Concerning segmented user data packets, the techniques of the present invention utilize one or more predetermined values in the length indicator (LI) field in the headers of the certain ones of the plural AAL2 packets to carry information other than packet size information. Further, the techniques of the present invention use the User-to-User indicator (UUI) field of the AAL2 packets to carry AAL2 information such as segmentation notification and sequence-derivable information. For AAL2 packets which carry non-segmented user data packets (e.g., user data packets which can fit with the maximum size of a single AAL2 packet), the length indicator (LI) field contains the actual length of the AAL2 packet in conventional manner.

Abstract: In a multi-layer telecommunications system which includes an application layer and a transport layer, differing transport technologies are interworked without terminating the application layer signaling or without involving a technology interworking in the control plane of the application layer (e.g., without interworking in the application signaling). In various illustrated embodiments, the application layer is a radio network layer of a wireless telecommunications system. In at least some embodiments of the present invention a transport layer interworking function is situated on an interface between two nodes of the radio access network (RAN). The interworking function can be located in a separate node which may be a node having both ATM and internet protocol (IP) interfaces. There are numerous modes of implementing the interworking of the present invention, regardless of which interface is affected (e.g., an Iur interface, an Iu interface, or an Iub interface). A first interworking mode involves interworking with q.aal2 signaling. There are various ways or options of implementing the interworking with q.aal2 signaling. A first such example option is to use an IP specific signaling protocol over the IP network. A second example option is to use q.aal2 signaling over the IP network to/from the IP node. In one of its aspects, the present invention also provides an optimization feature in the event that nodes on both side of the interface (Iu interface, Iur interface, or Iub interface) are IP-connected nodes. Another interworking mode involves obtaining address and binding identifier parameters to be included in application signaling messages by consulting a transport layer interworking gateway. Yet another mode of implementing interworking for the present invention involves tunneling.
