摘要:
A method for modulating scanning behavior of a wireless user equipment (UE) device includes determining a geographic area location where the wireless UE device is located and responsive to determining that a radio access technology (RAT) previously available in the geographic area location is not currently available, modifying the frequency of searches for the radio access technology. A corresponding wireless user device is also shown.

Apparatus, and an associated method, for facilitating selection of an I-WLAN PLMN. A PLMN listing is created and maintained at a wireless device. The listing includes entries that identify PLMN together with their associated access technology indicators. The wireless device creates a list of available I-WLAN PLMNs. And a selector and comparator compare identities on the listing together with the list of available I-WLAN PLMNs. Selection is made of a PLMN on both the listing and the list and also exhibits an appropriate access technology capability identified by the access technology indication.
摘要:
Systems and methods for prioritizing network selection to achieve PLMN continuity when moving between networks of different types are provided. In network centric embodiments, the network generates a PLMN list that prioritizes networks for which PLMN continuity is possible, for example when moving from cellular to GAN or vice versa. In mobile station centric embodiments, the mobile station generates a PLMN list that prioritizes networks for which PLMN continuity is possible, for example when moving from cellular to GAN or vice versa. This can be based on the mobile station recognizing past behaviour of the networks.

An aqueous based hair straightening composition having a pH from 12 to 14 comprising i) an hydroxide ion generator; and ii) from 0.5 wt % to 20 wt % of the total composition of urea in which the weight ratio of urea to hydroxide generator is greater than 1:1.
摘要:
A scheme is provided for acquiring network advertisement information in a network environment having one or more radio access networks (RANs), one or more core networks (CNs) and one or more service networks (SNS). A combination of codes is provided to a wireless user equipment (UE) device for facilitating discovery of applicable RAN-CN-SN combinations and subsequent network selection by the UE device.
摘要:
In one embodiment, a scheme is provided for effectuating generic access network (GAN) selection with respect to a user equipment (UE) device that is operable in wide area cellular network ((WACN) bands as well as in wireless access network bands (e.g., GAN bands and/or UMA bands). A network node (e.g., a GAN controller (GANC) or UMA network controller (UNC)) is equipped with logic for resolving service requirements as well as network information gathered by the UE device. Based thereon, an appropriate list of UNCs/GANCs is provided to the UE device for selection, the UNCs/GANCs being operable with one more wide area cellular networks identified for the UE device.
摘要:
Methods and apparatus for forming and maintaining an ad hoc mesh network suitable for reliable voice and data communications in underground, industrial and other hazardous environments. This invention includes support for cooperative negotiation of dedicated transmission bandwidth for all fixed network nodes, determination of network time synchronization without a pre-determined time master, discovery and merging of adjacent ad hoc mesh networks, and routing techniques for voice, data and network status packets which react instantaneously to network topology changes. Furthermore this invention provides a reliable communication network for mobile nodes carried by personnel and sensor nodes that are fixed or mobile that supports voice, data and tracking/situation awareness. A current application for this technology is a coal mine communication system with an operations center to dispatch, monitor and control coal mine operation including communication and location of mine personnel, and environmental conditions in the mine.
