Abstract: Disclosed is a method and system for release of a UE's context record in response to failure of air interface communication. As disclosed, a wireless communication system includes a base station that has a protocol stack defining a series of logical processing layers through which the base station sequentially processes data for transmission to a UE. The layers include an upper layer and a physical layer at which the base station processes the data for communication over an air interface to the UE. Accordingly, the base station detects failure of air interface communication between the base station and the UE. In response to detecting the failure, and without waiting to detect at the upper layer a further failure corresponding with the failure of the air interface communication, the base station transmits to a network controller a UE-context release request requesting release of bearer context that was established for the UE.

Abstract: Disclosed is a method and system that may help to expedite initiation of a packet-based real-time media session such as a VoIP session. Per the disclosure, the initial uplink grant that a base station provides to a UE in response to an access request may be an extent of uplink resources sufficient to carry just a radio-link-layer connection request. But when a UE is going to initiate a packet-based real-time media session, the UE may send a particular type of access request that is indicative of the plan to initiate a packet-based real-time media session, and responsive to the access request being of that particular type, the base station may then instead provide an initial grant of a greater extent of uplink resources sufficient to carry from the UE not only the radio-link-layer connection request but also a session initiation request (e.g., SIP INVITE) for the packet-based real-time media session.

Abstract: An access terminal establishes a session with a first radio access network (RAN). As a result, the access terminal receives a Unicast Access Terminal Identifier (UATI) assigned by the first RAN and establishes configuration settings for radio communications between the access terminal and the first RAN. The access terminal moves from the first RAN to a second RAN. Before the access terminal has a session established with the second RAN, the access terminal receives a request from a user to originate a call. In response, the access terminal sends the second RAN a connection request that includes the UATI assigned by the first RAN. The second RAN evaluates the UATI included in the connection request and determines that it was previously assigned to the access terminal by another RAN. Based on this determination, the second RAN grants the connection request by assigning a traffic channel to the access terminal.

Abstract: An example embodiment may involve defining an orthogonal frequency-division multiplexed (OFDM) wireless air interface that contains time-division multiplexed subframes. A primary signaling channel may be formed by modulation symbols that are statically allocated to fixed time positions of each subframe, and span contiguous subcarrier frequencies. A secondary signaling channel may be defined in the OFDM wireless air interface. The secondary signaling channel may be formed by modulation symbols that are dynamically allocated to time positions of one or more subcarrier frequencies, and span at least two consecutive subframes of the OFDM wireless air interface. A signaling message may be transmitted, on the primary signaling channel, to one or more WCDs. The signaling message may be transmitted in a first subframe of the consecutive subframes, and may identify the secondary signaling channel.

Abstract: In accordance with the disclosed methods and systems, while providing a service that enables user equipment devices (UEs) being served by a first network to engage in signaling with a second network via the first network, a controller or other network entity may detect an error condition associated with the service, such as a threshold-high level of signaling or an interface failure. In response to detecting the error condition, base stations in the first network may then direct one or more UEs being served by the first network to refrain from using the given service. As a result, the one or more UEs may refrain from using the given service and may instead use another approach to engage in signaling with the second network, which may enable the one or more UEs to circumvent the error condition until it gets remedied.

Abstract: A method, system, and apparatus for assigning resources to a wireless communication device that experienced a call drop. A RAN may receive an origination request from a mobile station and make a first determination that within a predetermined amount of time prior to receiving the origination request the mobile station experienced a call drop. Responsive to making the first determination, the RAN may make a second determination that the RAN should allocate a first extent of resources to the mobile station rather than allocating a second extent of resources to the mobile station. The first extent of resources may be less than the second extent of resources. Responsive to making the second determination, the RAN may allocate the first extent of resources to the mobile station in response to the origination request rather than allocating the second extent of resources to the mobile station in response to the origination request.

Abstract: A network node receives from a mobile terminal being served by a first coverage area a measurement report indicating signal level of a second coverage area detected by the mobile terminal. The network node then makes a determination, by considering PLMNs of the mobile terminal and of the coverage areas, of (i) whether the mobile node is a home mobile node of the first coverage area and (ii) whether the mobile node is a home mobile node of the second coverage area. Based on that determination, the network node then selects a handoff threshold. And based on the handoff threshold and the reported signal level, the network node decides whether to trigger handoff of the mobile terminal from the first coverage area to the second coverage area. The network node then triggers the handoff if the decision is to do so.

Abstract: A base station or a UE may use another base station's carrier-aggregation policy for a cell provided by the other base station as a basis to control handover of the UE from being served by the base station to being served by the other base station. As one example, a first base station may use a second base station's carrier-aggregation policy for at least one of multiple co-located cells provided by the second base station as a basis to control handover of the UE from being served by the first base station to being served by the second base station. As another example, a UE may use a second base station's carrier-aggregation policy for one of multiple co-located cells provided by the second base station as a basis to control cell reselection.

Abstract: When a UE engages in application-layer session setup signaling with a session server via a radio access network and gateway, the UE conveys in its session setup signaling an indication of the UE's observed air interface quality (e.g., received signal strength or signal to noise ratio) and perhaps an indication of a characteristic of an neighboring air interface (e.g., a duplex configuration or band of the neighboring air interface). The session server then reports the UE's indicated air interface quality and perhaps neighboring air interface characteristic to a policy server, and the policy server uses that information as a basis to select a quality of service level for a bearer to be established between the UE and the gateway for carrying media content of the session. The policy server then invokes establishment of a bearer having the selected quality of service level.

Abstract: A method and system for allocating frequency bandwidth between a relay backhaul link and a donor access link, based at least in part on the PLMN(s) to which UE(s) served by the relay node subscribe. The donor base station or another controlling entity may determine the PLMN(s) to which one or more UEs currently served by the relay node subscribe and, based at least in part on the determined PLMN(s), may assign a PLMN-priority level to the relay. Based at least in part on the PLMN-priority level assigned to the relay, the controlling entity may then establish an allocation of the frequency bandwidth between the relay backhaul link and the donor access link, and the donor base station may apply that established allocation.
