Abstract: Techniques for switching a user equipment (UE) between wireless systems by first establishing a connection with a target system before disconnecting from a serving system are disclosed. In one design, the UE may initially communicate with a first wireless system (e.g., a WLAN system) of a first radio technology. The UE may receive a page to establish a connection with a second wireless system (e.g., a cellular system) of a second radio technology. The first and second wireless systems may be part of a small cell. The page may be sent by the second wireless system to the UE in response to a decision by a network entity to switch the UE from the first wireless system to the second wireless system. The UE may establish a connection with the second wireless system in response to the page and may thereafter terminate communication with the first wireless system.

Abstract: The present disclosure presents methods and apparatuses for improved wireless node transmission of advertising beacons based on, for example, the presence of sufficient wireless node resource availability and one or more user equipment (UE) wakeup schedules. For example, the present disclosure describes example methods of advertising beacon transmission by a wireless node, which may include determining that a resource availability opportunity exists for supporting a UE at the wireless node. In another aspect, methods may include tuning to a non-serving channel based on determining that the resource availability opportunity exists. According to such example methods, the non-serving channel may be different from a serving channel of the wireless node. Furthermore, the example methods may include transmitting an advertising beacon on the non-serving channel. Upon successful receipt of the advertising beacon, the UE may scan for the serving channel of the wireless node for subsequent wireless network access.

Abstract: Methods, devices, and computer program products for selective scanning of ad-hoc networks are described herein. In one aspect, a method includes receiving a message identifying a number of times the message has been forwarded. The method further includes selectively scanning for other ad-hoc networks based on the identified number. In one aspect, a root device for an ad-hoc network is responsible for generating synchronization messages for nodes of the ad-hoc network. The synchronization message includes a count of the number of times the synchronization message has been forwarded. When the hop count reaches a limit, the synchronization message is no longer retransmitted or forwarded by receiving nodes. Nodes receiving this message may recognize they are positioned near the edge of the ad-hoc network. In at least one embodiment, these nodes may selectively scan for other ad-hoc networks based on the hop count reaching or exceeding a predetermined threshold.
