Abstract: Systems and methods are described for determining candidates for handover of wireless devices in a wireless network. An application requirement, a mobility, and an activity factor associated with wireless devices in communication with a first access node may be used to classify wireless devices. The first access node may then receive signal information and identifiers of second access nodes from the wireless devices. The second access node identifiers may be transmitted in response to a reporting event based on a first signal level of the first access node and second signal levels of the second access nodes. A communication link between the first access node and each second access node may be used to transmit second access node network characteristics to the first access node in order to determine if the second access node is a candidate for handover of wireless devices having classification criteria.

Abstract: A smart card is used with a network based system to providing portable telecommunication and computing services. In an exemplary embodiment the smart card holds a user authentication code and user telephony account information. The smart card transfers the user authentication code and the account information to one of a plurality of geographically dispersed card readers which are each connected to a local telephony device. When the smart card is plugged into a first card reader, telephone calls directed to the smart card user's follow-me telephone number are received at a first local telephony device. When the smart card is plugged into a second smart card reader, telephone calls directed to the follow-me telephone number are received at a second telephony local device. Hence the user is enabled to receive and place calls using any of the geographically dispersed telephony devices as though they were his/her own personal landline or cellular telephone supplied by his/her telephony services provider.

Abstract: For maintaining a certain quality of service for a certain type of data traffic, the data traffic may be directed to a corresponding bearer established with respect to a user equipment. By sending probe packets on the bearer and/or on a further bearer and receiving a response packets returned in response to the probe packets, a parameter corresponding to a time period between sending a probe packet and receiving the corresponding response packet can be measured. On the basis of the measured parameter, a bearer control procedure with respect to the user equipment is initiated. This bearer control procedure may for example include directing data packets of selected data traffic from one bearer to another bearer, modification of at least one quality of service parameter of a bearer, and/or establishing or releasing a bearer.

Abstract: A shared signaling channel can be used in an Orthogonal Frequency Division Multiple Access (OFDMA) communication system to provide signaling, acknowledgement, and power control messages to access terminals within the system. The shared signaling channel can be assigned to a predetermined number of sub-carriers within any frame. The assignment of a predetermined number of sub-carriers to the shared signaling channel establishes a fixed bandwidth overhead for the channel. The actual sub-carriers assigned to the channel can be varied periodically, and can vary according to a predetermined frequency hopping schedule. The amount of signal power allocated to the signaling channel can vary on a per symbol basis depending on the power requirements of the communication link. The shared signaling channel can direct each message carried on the channel to one or more access terminals. Unicast messages allow the channel power to be controlled per the needs of individual communication links.

Abstract: Techniques are provided for broadcasting history or coarse representations or both of stroke media and other media. Levels are created for media, and the levels are periodically broadcast. The levels segment the media and allow the media to be examined with details that range from coarse to fine or examined with varying importance or both. The periodic broadcast of the levels provides history of the media. In particular, for stroke data, levels of detail are determined through a certain method. Each level of detail is periodically broadcast. The levels of detail may be shown by themselves or combined at a receiver to create segmented views of the stroke data. A user can select a coarse view of the stroke data to quickly see the stroke history. Additionally, techniques are provided for quickly and repeatedly accessing data elements in already existing data structures. Generally, a description is created that describes data elements in a preexisting data structure.

Abstract: A wireless device includes a wireless transceiver configured to transmit to and receive from nodes in a wireless sensor network (WSN) and control logic coupled to the first wireless transceiver. The wireless transceiver transmits a wireless packet to a node in the WSN based on the transmission coinciding with a break in transmissions for a second wireless network. Based on the wireless transceiver being configured to transmit the wireless packets utilizing time synchronized channel hopping, slot frames for packet transmissions in the WSN are time offset so as not to coincide with transmissions made on the second wireless network. Based on the wireless transceiver being configured to transmit the packets utilizing coordinated sampled listening, wake up sequence transmissions for the WSN are time offset so as not to coincide with the transmissions made on the second wireless network.
