Abstract: Embodiments of a WiFi system and method for time-sliced associations for make-before-break handover in the WiFi system are generally described herein. In some embodiments, the method monitors metrics of a serving channel of the WiFi system to determine whether to increase a channel scanning rate of target channels of the WiFi system. The channel scanning rate of the target channel may be increased in response to the metrics. A time-sliced association with one or more target cells on the target channel may be performed while an association with a serving cell on the serving channel may be maintained. The wireless client may be transitioned from the serving cell to the target cell in response to the metrics while obscuring the complexity from the device operating system and active applications.

Abstract: A resource efficient approach for push-to-talk (PTT) services over a mobile communications network is provided. A remote terminal (UT) receives a command for initiating a PTT session. The UT generates a RAB binding create message, including a PTT session identifier and RAB binding information, and transmits the RAB binding create message to a wireless gateway. The UT receives a RAB binding response from the wireless gateway, and performs a protocol signaling process for establishing PDP bearers, and for establishing the PTT session on a PTT server. The UT receives a command for initiation of media transmission for the PTT session, generates talk burst (TB) request message, and transmits the request message to the wireless gateway (the TB request message is transmitted via media access control (MAC) layer control messaging). In response, the UT receives a talk burst grant message from the wireless gateway.

The load balancer receives a Session Traversal Utilities for Network Address Translation/Translator (NAT) (STUN) request from a caller to establish media. The STUN request includes a conference identifier (ID) for the session. The load balancer determines an availability of each of the media agents in the cluster, selects a media agent for the caller based on the conference ID and the determined media agent availabilities, forwards the STUN request to the selected media agent, and routes media packets between the caller and the selected agent for the session.

Abstract: A system for providing oversubscription of pipeline bandwidth comprises a steer module, an absorption buffer, an ingress packet processor (IPP), a memory management unit (MMU), and a main packet buffer. The steer module receives packets that include start of packet (SOP), middle of packet (MOP), and end of packet (EOP) cells, attaches a packet identifier to the cells, passes the MOP and EOP cells to the MMU, and stores the SOP cells and EOP metadata in the absorption buffer. The IPP processes the SOP cells and EOP metadata and passes the same to the MMU. The MMU stores the MOP, EOP, and processed SOP cells in the main packet buffer, combines, upon receiving the processed EOP metadata of each packet, the processed SOP cell, the MOP cells and the EOP cell of each packet to reconstruct each packet, and queues each reconstructed packet in an egress port queue.

Abstract: Methods and apparatus for the automated altering of wireless device states in response to detected connection behaviors. In one embodiment, a mobile device receives network parameters, some of which are incorrectly configured, from a base station (or access point). To ensure the proper behavior of the mobile device, the device reviews the network provided parameters to determine if one or more of the parameters has been set incorrectly. If so, the device locally alters its own settings to mitigate the incorrect operation associated with the incorrect network provided parameters. In second exemplary embodiment, a number of tolerances are utilized to ensure the proper operation of the mobile device while maintaining an active link. Upon violation of one or more of these tolerances, the device breaks the active link to the wireless network.

Abstract: Systems, methods, and user equipment can involve transmitting Acknowledgement/Negative Acknowledgement (ACK/NACK) bits for carrier aggregation between a first cell and a second cell in a User Equipment (UE). With the UE, for a sub-frame, a first number of ACK/NACK bits for the first cell can be compared with a second number of ACK/NACK bits for the second cell. If a first number of ACK/NACK bits for the first cell is less than a second number of ACK/NACK bits for the second cell, an ACK/NACK bit position from the first cell can be used to transmit an ACK/NACK bit for the second cell. In some implementations, one or more DTX bits can be used to set the number of ACK/NACK bits in the first cell equal to the number of ACK/NACK bits in the second cell.

Abstract: In an embodiment of a wireless network, when a node joins the network and receives a routing advertisement, such a node transmits the routing advertisement to all its neighbors. The node then receives transmission from the neighboring nodes indicating interest in joining the advertised network. If more than a threshold number of neighboring nodes are interested in the advertised route, the newly joining node inserts the route advertisement in a beacon transmission. If there is not a threshold level of interest, the node unicasts only to the neighbors who indicated interest in the advertised network. In an embodiment, the node repeats the above steps on a predetermined time basis (e.g., one per day) in order to determine interest in the advertised route that may have newly arisen.
