    摘要: Techniques for sending control information in the header of multiple packets are described. The techniques may allow more control information to be sent using a small number of overhead bits per packet. In one design, a first node (e.g., a network entity) may determine control information to send to a second node (e.g., a UE or another network entity). The first node may send the control information in the header of multiple packets toward the second node. In one design, the control information may include congestion information indicative of traffic congestion at the first node. The congestion information may be sent using Explicit Congestion Notification (ECN) bits in the header of IP packets. The first node may send the control information with or without coding and for all packets or a specific data flow. The first node may also send a synchronization sequence prior to the control information.

    摘要: Providing for establishment of local Internet Protocol access (LIPA) for cellular communication is provided herein. According to particular aspects of the subject disclosure, provided are mechanisms to identify a request to establish a packet network connection as a request for a LIPA context. Once identified, a local gateway associated with the UE or with a subscriber-deployed base station is identified, and a packet context is established to support LIPA traffic for the UE. Additional mechanisms support UE mobility from one base station to another, including identifying and terminating inactive LIPA contexts. Further, a UE is described that can recognize and facilitate the establishment of a LIPA context for applications executing at the UE.

    摘要: Local breakout is provided by one or more nodes (e.g., a local access point and/or a local gateway) in a wireless network to facilitate access to one or more local services. In conjunction with local breakout, multiple IP points of presence relating to different levels of service may be provided for an access point. For example, one point of presence may relate to a local service while another point of presence may relate to a core network service. IP point of presence may be identified for an over-the-air packet to indicate a termination point for the packet. Also, different mobility management functionality may be provided at different nodes in a system whereby mobility management for a given node may be provided by a different node for different types of traffic. Thus, an access terminal may support multiple NAS instances. In addition, different types of paging may be provided for different types of traffic. Furthermore, messages associated with one protocol may be carried over another protocol to reduce complexity in the system.

    摘要: Providing for select Internet Protocol traffic offload (SIPTO) in a mobile communication environment is described herein. By way of example, SIPTO traffic can be facilitated via local packet gateways (P-GWs) that provide an interface to the Internet or a like data network, in addition to a centralized gateway GPRS support node (GGSN). Eligibility for SIPTO can be on a user equipment (UE) by UE basis; for instance, relying on stored subscription or account information to determine SIPTO eligibility. In particular aspects, eligibility for SIPTO can also be based on a packet network by packet network basis, or a combination of the foregoing. This enables flexibility in determining whether SIPTO can be established for a given UE in a given location, and can be based for instance on UE capability, subscription status information, data network capability, tariff rates, and so on, as well as different legal requirements of government jurisdictions.

    摘要: A multi-mode access point supports different radio access technologies (e.g., Wi-Fi and cellular) for serving multi-mode access terminals. To provide improved service for such an access terminal, the access point may redirect the access terminal from a first type of radio access technology to a second type of radio access technology under certain circumstances. A decision to invoke such a redirection may be based on, for example, at least one of: traffic conditions on the first type of radio access technology, traffic conditions on the second type of radio access technology, and whether a backhaul for the access point is currently a bottleneck for access point communication.
