Abstract: A wireless user device maintains wireless access via a public land mobile network and, while maintaining such wireless access, participates with one or more other devices in an instant communication session delivered via a carrier instant communications processing element of the public land mobile network. The session communications from the wireless user device are routed through a processing element of a private communication network for an assignment of a generic identifier to the session communications in place of a user identifier of the wireless user device, and then routed back to the public land mobile network to the carrier instant communications processing element for delivery to the one or more other devices in the instant communication session.

If no other cell providing access to the network is available to the mobile communication device, a forced reselection of a radio access technology may be performed.

Abstract: A multi-mode communication device having a scan optimizer capable of prioritizing scan frequencies for different radio access technologies (RATs) during a network search. The scan frequency prioritization may be based on various network coverage considerations associated with RAT availability, RAT density within a region, geographic location, historic attachment for the multi-mode device, an operation mode of the multi-mode device, etc. The multimode device can utilize its scan optimizer to generate an optimized scan schedule to be employed for a limited duration during a network search to improve its likelihood of success in detecting and/or attaching to a network associated with a prioritized RAT. A default scan schedule having equal scan frequency prioritization can be employed by the multi-mode device at a time when the limited duration of the optimized scan schedule expires and no networks associated with a prioritized RAT have been acquired.

Abstract: In video conferencing over a radio network, the radio equipment is a major power consumer especially in cellular networks such as LTE. In order to reduce the radio power consumption in video conferencing, it is important to introduce an enough radio inactive time. Several types of data buffering and bundling can be employed within a reasonable range of latency that doesn't significantly disrupt the real-time nature of video conferencing. In addition, the data transmission can be synchronized to the data reception in a controlled manner, which can result in an even longer radio inactive time and thus take advantage of radio power saving modes such as LTE C-DRX.
