Patent number: 8934387Abstract: A BT receiver RF front end receives RF energy in a sequence of BT scan windows. Throughout a scan window, the front end is tuned to one hop frequency. Before and after the window the front end is in a disabled state. A WLAN energy detector processes an output of the front end during the window and determines whether more than a predetermined amount of RF energy was received onto the front end during the window. A BT baseband processor attempts to demodulate the output of the front end. If the WLAN energy detector determines that the predetermined amount of RF energy was received and if a BT signal could not be demodulated, then a WLAN wake-up signal is asserted, thereby causing a WLAN transceiver to be powered up to receive WLAN signals. BT scan intervals are varied in duration to facilitate a BT scan window overlapping a WLAN beacon.Type: GrantFiled: May 5, 2011Date of Patent: January 13, 2015Assignee: QUALCOMM IncorporatedInventors: Jianqiang He, Kai Bai, Gene Fong

Patent number: 8666418Abstract: The present invention discloses a method and system for softly unloading a core network element in a multi-homing networking mode, for solving the technical problem of high call loss rate caused by unloading the multi-homing core network element due to reasons like upgrading, failure, or removal. In the present invention, the to-be-unloaded multi-homing core network element is set into an office direction blockage state, and the multi-homing core network element will not be distributed with a new service; and the to-be-unloaded multi-homing core network element is unloaded when the existing services thereon are processed into a predetermined state. The present invention reduces the call loss rate and mitigates the impact on the existing services when the multi-homing core network element needs to be unloaded.Type: GrantFiled: December 24, 2009Date of Patent: March 4, 2014Assignee: ZTE CorporationInventors: Shumei Gao, Jianqiang He
