Opportunistic use of wireless network stations as repeaters

Номер: US20120014313A1
Принадлежит: Microsoft Corp

Implementation of opportunistic use of stations in a wireless network as repeaters is described. In one implementation, a station detects the existence of rate anomaly in a wireless network. In response to the rate anomaly, the station may transform into a software repeater for certain other neighboring stations. The repeater function allows for the relaying of packets sent by these neighboring stations to the access point and vice versa. The other neighboring stations, owing to their relative proximity to the repeater station, transmit data at a higher rate to the repeater station. Thus, the removal of the slower stations reduces clogging of the access point and increases the overall data rate within the wireless network. Further, a zero-overhead network coding protocol may be implemented in conjunction with the repeater function to increase capacity of the wireless network.

In a mobile communication system, a handover of a terminal device (MT) from a macrocell base station (eNB) to a small cell base station (HeNB) is controlled via a host device (MME or HeNB-GW). Physical cell ID deployment map information (PCI deployment map information), which includes at least information (PCI/CGI map information) indicating the correspondences between physical cell IDs and unique cell IDs of CSG cells for which access is granted, is generated in the host device (MME or HeNB-GW). When the terminal device measures the reception quality for surrounding CSG cells for handover control to any of the CSG cells, the terminal device uses the PCI deployment map information to generate a measurement result report. Thus, a service interruption caused by handover control to an inaccessible small cell can be avoided, and the wait time for handover control can be reduced.

Methods And Apparatus For Use In Initiating Vertical Handover Based On Comparative Evaluation Of WLAN And WWAN Signal Qualities

Номер: US20120163344A1
Принадлежит: Research in Motion Ltd

Techniques in a mobile device for use in initiating vertical handover of a voice or a data call between a wireless local area network (WLAN) and a wide area wireless network (WWAN) are described. The mobile device performs communication operations for maintaining the voice or the data call via the WLAN or the WWAN. During the voice or the data call, the mobile device identifies a WLAN signal quality value of signals with the WLAN, as well as a WWAN signal quality value of signals with the WWAN. The mobile device then performs a comparative evaluation of the WLAN and the WWAN signal quality values, and initiates a vertical handover of the voice or the data call between the WLAN and the WWAN based on the comparative evaluation of the WLAN and WWAN signal quality values. The comparative evaluation may involve calculating a signal indicator value which is based on a ratio of the WLAN and the WWAN signal quality values. Alternatively, the comparative evaluation may involve comparing or finding the difference between the WLAN and the WWAN signal quality values.
