  • Patent number: 8509162
    Abstract: Systems and methodologies are described that facilitate scheduling over multiple hops in a wireless communication network. Radio resources can be partitioned into sets of sub-frames that can be allocated statically and/or dynamically. Statically allocated radio resources can be reassigned over time based on the loading on each hop and/or throughput imbalance. In addition, dynamic assignment of sub-frames to each hop can be based on traffic or channel conditions. Moreover, the radio resources can be dynamically allocated in a distributed scheme, wherein a base station controls the scheduling of resources, or a centralized scheme, wherein a relay station controls the scheduling of resources. Furthermore the allocation of radio resources can be transparent or explicit. In the transparent case, the access terminal listens directly to the base station, and the relay station does not transmit control information, such as DL or UL assignments.

  • Patent number: 8442060
    Abstract: Signaling-only access may be established with an access node under certain circumstances such as, for example, upon determining that a node is not authorized for data access at the access node. A node that is not authorized for data access at an access node may still be paged by the access node through the use of signaling-only access. In this way, transmissions by the access node may not interfere with the reception of pages at the node. A first node may be selected for providing paging while a second node is selected for access under certain circumstances such as, for example, upon determining that the second node provides more desirable service than the first node.

  • Patent number: 8401068
    Abstract: Systems and methodologies are described that facilitate assigning TEIDs, or portions thereof, to UEs or other devices during network attachment and/or dedicated bearer activation using one or more cell relays. Relay eNBs can request bearer establishment from a UE, which can be based on receiving an attach accept from an upstream node during attachment for the UE, receiving a bearer setup request from the upstream node, and/or the like. Once a bearer establishment response is received from the UE, the relay eNBs can store a TEID relating to the bearer. This can be a TEID that is at least partially received in the attach accept or bearer setup message, generated for the UE upon receiving the bearer establishment response, and/or the like. The TEID, or portion thereof, can be utilized for subsequent packet routing to the UE through one or more cell relays.

  • Patent number: 8285285
    Abstract: Systems and methodologies are described that facilitate utilizing reselection indicators in reselecting access points in wireless communications. In particular, an indicator can be provided relating to a restricted association access point that specifies whether intra-frequency reselection is allowed. If so, a mobile device receiving the indicator can reselect to other access points, to which it has access, operating in a similar frequency. If not, the mobile device can evaluate access points in other frequencies so as not to cause substantial interference to the restricted association access point. In addition, a predicted level of interference caused by communicating with an intra-frequency access point can be computed and evaluated to override the reselection indicator, in some cases. Thus, a restricted association access point can control reselection for some devices to mitigate interference while allowing the devices to override prohibitive restricted access points.

  • Patent number: 8213405
    Abstract: Systems and methodologies are described that facilitate synchronizing timing among wireless nodes in a wireless communication network. A tracking wireless node can synchronize to a global positioning system (GPS) signal if available. Alternatively, the tracking wireless node can receive quality metrics related to one or more target nodes. The quality metrics can relate to parameters that can be utilized to evaluate the target node for timing synchronization. Based on the quality metrics, the tracking wireless node can select a target wireless node for timing synchronization. The tracking wireless node can subsequently synchronize timing with the target wireless node. In addition, the tracking wireless node can continually evaluate surrounding wireless nodes to detect whether other wireless nodes have higher quality metrics than the current target wireless nodes and can accordingly resynchronize with nodes having higher metrics.

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.

  • Publication number: 20100203865
    Abstract: Systems and methodologies are described that facilitate managing access control to Closed Subscriber Groups (CSGs) in a wireless communication environment. A user equipment (UE) can store an operator CSG list, which can be read only and controlled by an operator. Further, the operator CSG list can lack synchronization to a CSG subscription for the UE retained in the network. Thus, upon selecting to access a CSG cell associated with a CSG with a corresponding CSG Identifier (ID) included in the operator CSG list of the UE, a reject message that indicates that the UE lacks authorization for the CSG can be received. Moreover, the CSG ID can be stored as a forbidden CSG ID of the UE in a set of forbidden CSG IDs in response to receipt of the reject message when the CSG ID is included in the operator CSG list.

  • Publication number: 20100197307
    Abstract: Problems caused by interaction between paging optimization and synchronizing CSG information are mitigated by setting a network indication indicating, for example, that a subscriber is no longer a member of a CSG, but the network has not yet received confirmation that an access terminal associated with the subscriber has been informed of this. A timer-based scheme may be employed for removing a CSG ID from the subscriber information for a subscriber once it is determined that the subscriber is no longer a member of the CSG. In addition, a temporary member of a CSG may determine whether it is still a member of a CSG upon expiration of a CSG timer. Also, the frequency with which an access terminal registers may be changed based on various criteria. Furthermore, an allowed CSG list may be selectively included in a page message depending on the destination of the page message.

  • Publication number: 20100173626
    Abstract: Handover parameter settings are automatically adapted in access points in a system to improve handover performance. Reactive detection techniques are employed for identifying different types of handover-related failures and adapting handover parameters based on this detection. Messaging schemes are also employed for providing handover-related information to access points. Proactive detection techniques also may be used for identifying conditions that may lead to handover-related failures and then adapting handover parameters in an attempt to prevent such handover-related failures. Ping-ponging may be mitigated by adapting handover parameters based on analysis of access terminal visited cell history acquired by access points in the system. In addition, configurable parameters (e.g., timer values) may be used to detect handover-related failures.

  • Publication number: 20100161794
    Abstract: Information is maintained to assist in determining whether an access terminal is allowed to establish communication with an access point associated with a closed subscriber group (CSG). For example, CSG subscription information for visiting access terminals may be maintained at a local server. In this way, a network may use the locally stored CSG subscription information for a given access terminal to determine whether to allow that access terminal to access an access point in the network. In addition, multiple CSG lists may be maintained at an access terminal. For example, an access terminal may maintain a first list that is updateable by an operator and a second list that is updateable by a user. Here, the updating of one list may be based on a change in the other list.

  • Publication number: 20100159899
    Abstract: In-band provisioning enables subscribers to manually provision themselves via an access point at which the subscribers would not otherwise be allowed access. For example, a subscriber may be temporarily accepted by a restricted access point (e.g., an access point that belongs to a closed subscriber group). The subscriber is then given limited access to enable the subscriber to be provisioned at the access point. For example, the subscriber may be provisioned for full access at the access point if the subscriber presents a valid authorization credential to a provisioning entity.
