  • Patent number: 8259702
    Abstract: Addressing methods and apparatus which use airlink resources in an efficient manner are described. In order to use airlink resources efficiently, a variety of address types are supported. The number of bits in the address may vary depending on the type. In order to support a variety of different address types, of different lengths, in one embodiment, an address used for communications over an airlink is constructed by including in the address an address type field used to communicate an address type indicator and, optionally, an address field used to communicate an address value. The address field is variable in length and may be null, requiring the communication of no bits in this field, for certain types of addresses. Four types of addresses which may be supported include: i) an Access Terminal assisted address, ii) a Network assisted address, 3) a Pilot PN based address; and 4) a reserved address.

  • Patent number: 8254364
    Abstract: A route protocol is established whereby a mobile device can communicate to a multitude of (receiving) base stations though a tunnel created through a serving base station. A message that includes a Route Creation Header can be transmitted by the mobile device to create the tunnel. The Route Creation Header is reviewed by the receiving base station while the mobile device is in a Waiting-To-Open State. Various errors might occur with respect to the Route Creation Header. These errors can be conveyed to the mobile device by base station by setting one or more error code fields. Once the errors are resolved, another attempt to create a tunnel with base station can be made, if desired.

  • Patent number: 8199688
    Abstract: Embodiments describe overlaying a broadcast multicast channel on top of a unicast network. Messages can be generated by protocols in a broadcast/multicast (BCMC) stack and tunneled through an IRTP of a serving access node. These messages can be transmitted on a BCMC channel and/or a unicast channel. Other messages can be generated by protocols in a unicast stack and tunneled to a B-IRTP of a BCMC Access node and transmitted on a BCMC channel to an access terminal.

  • Publication number: 20120122496
    Abstract: Systems and methods are described that mitigating coverage gaps near region boundaries using a plurality of multi-sector broadcast (MSBC) paging channels in wireless networking environments. One or more MSBC paging channels can be assigned unique time slots, such that although the channels can be identical, they are disjointed in time. Accordingly, such channels and/or dynamically generated paging zones associated therewith can be overlapped in areas where wireless device density is high and requires substantial paging capacity. Additionally, a single paging channel can be employed in multiple instances in a paging region without overlap to mitigate inter-channel interference.

  • Patent number: 8179811
    Abstract: An algorithm for improving efficiency of data attachment points (DAPs) in a wireless access network (AN) is provided herein. By way of example, the algorithm can identify a serving access point (APs) coupling an access terminal (AT) to the wireless AN. A cost metric for the serving AP can be determined with respect to at least one data network access gateway (AGW) of the wireless AN. The cost metric can be compared with a similar cost metric of a current or default DAP assigned to the AT. If the cost metric of the serving AP is lower than the cost metric of the current/default DAP, the DAP can be re-assigned to the serving AP, minimizing wireless AN resource costs associated with the DAP.

  • Patent number: 8179903
    Abstract: 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.

  • Patent number: 8160648
    Abstract: Receiver diversity in a wireless device is controlled in response to operating conditions, transmission requirements, and control settings. The control of diversity reduces power consumption by enabling receive diversity on given conditions. Operating conditions, transmission requirements, and control settings are used separately or used in conjunction to determine whether benefits of multi-antenna receive diversity, such as higher link capacity, higher data throughput, lower transmit power, and lower error rate, warrant the higher power cost of the diversity.

  • Patent number: 8155620
    Abstract: In a converged communication network, IP data packet services are provided by a core network to access terminals via radio access nodes (RAN). By positioning accounting report triggering closer to the usage, accuracy and comprehensive of accounting is achieved, which can also reduce overhead burdens on the core network. Additional responsibility is given to an access gateway (AGW) between an enhanced base station (eBS) of the RAN and the core network that can reduce the volume and increase the accuracy of accounting message traffic to an authentication, authorization and accounting (AAA) server of the core network. The AGW informs the eBS of accounting rules to be used in making air link records that are merged and formatted in accordance with an accounting protocol for sending to the AAA server, to address duration and volume based accounting needs, postpaid and prepaid accounting types, and user, service and flow based accounting categories.

  • Patent number: 8134952
    Abstract: Methods and apparatus for communicating between an access terminal (AT) and an Access Point (AP) are described. For communications over the air link, between an AP and an AT a PN (Pseudo-random Noise) code based address is used as an AP identifier, e.g., address. The PN code based address may be based on Pilot PN code based signals received from an AP. Thus, the PN based AP address may be determined from pilot signals received from an AP. The PN based AP address may be a shortened version of a PN code corresponding to an AP, a full PN code corresponding to an AP, or a value which can be derived in a known manner from a PN code corresponding to an AP.
