  • Patent number: 8638682
    Abstract: Measurements are conducted on one or more carriers in a case where an access terminal supports reception on multiple carriers. Upon determining that an access terminal is capable of concurrently receiving on a given set of carriers, a measurement is conducted on one or more carriers of the set while receiving on or more other carriers of the set. Conversely, upon determining that an access terminal is not capable of concurrently receiving on a given set of carriers, a measurement is conducted on one or more carriers of the set while not receiving on or more other carriers of the set. In addition, data transfers to or from an access terminal on a carrier may be restricted (e.g., data transfers not scheduled or only low priority data transfers scheduled) during one or more subframes before or after the access terminal conducts a measurement on another carrier.

  • Patent number: 8626162
    Abstract: Systems and methodologies are described that facilitate distributing and/or utilizing a Closed Subscriber Group (CSG) Identifier (ID) that identifies a CSG corresponding to a base station and a CSG indication that distinguishes between the base station permitting access to members of the CSG and permitting access to members and non-members of the CSG. For instance, the CSG ID can uniquely identify the CSG corresponding to the base station. A mobile device can receive the CSG ID and the CSG indication from the base station. Further, the received CSG ID can be compared to CSG IDs included in an allowed CSG list to recognize whether the mobile device is a member or a non-member of the CSG. Moreover, a preference for selecting the base station as compared to a disparate base station can be generated as a function of the received CSG ID and CSG indication.

  • Patent number: 8611306
    Abstract: Systems and methodologies are described that facilitate fetching a native security context between network nodes in a core network after an inter-system handover of a mobile device. For instance, a mobility message that is integrity protected by a security context (e.g., the native security context, a mapped security context, . . . ) can be obtained at a network node from the mobile device. Further, the network node can send a request to a disparate network node within a core network. The request can include information that can be used by the disparate network node to establish that the mobile device is authenticated. Moreover, the native security context can be received from the disparate network node in response to the request. Accordingly, the native security context need not be recreated between the network node and the mobile device.

  • Patent number: 8588773
    Abstract: Systems and methodologies are described herein that facilitate improved cell search and selection in a wireless communication system. For example, a terminal as described herein can utilize one or more Closed Subscriber Group (CSG)-specific offset and/or hysteresis parameters as described herein to increase the amount of time on which the terminal is allowed to camp on a desirable cell. Additionally, specialized reselection timing can be employed as described herein to increase a delay associated with selecting a Home Node B (HNB) or Home Evolved Node B (HeNB) cell, thereby reducing power consumption associated with rapid cell reselection operations in a densely populated network environment. Further, a two-step reselection process can be performed as described herein in the context of selecting a frequency for cell reselection, thereby mitigating the effects of rapid reselection between cells and/or frequencies due to CSG cell prioritization.

  • Patent number: 8571550
    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.

  • Patent number: 8520594
    Abstract: Problems caused by interaction between paging optimization and synchronizing closed subscriber group (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 identifier (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.

  • 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.
