Publication number: 20130194938Abstract: There is provided a mechanism for controlling communications conducted in multiple frequency bands so as to decrease an interference level between the communications. When an interference situation caused between a first set UL communications performed on at least two different frequency bands and a DL communication performed on another frequency band is determined, a frequency carrier deactivation processing is conducted so as to deactivate either one of carriers of the at least two frequency bands of the set of UL communications. The deactivation processing comprises for example an autonomous denial on the UE side or an interference reporting with deactivation on the eNB side.Type: ApplicationFiled: February 6, 2012Publication date: August 1, 2013Applicant: Renesas Mobile CorporationInventors: Antti Oskari Immonen, Jouni Kristian Kaukovuori, Jari Isokangas, Jukka Ranta

Patent number: 8477752Abstract: A user equipment UE with an active connection (radio or logical) with a wireless network needs to establish an emergency service. The UE unilaterally deactivates an active session or context with the wireless network, and thereafter sends to the wireless network signaling to establish the emergency service, in which the signaling specifically identifies the service as an emergency service. In one embodiment (FIG. 1) the UE locally detaches from an active packet domain communication and sends an emergency attach so as to clear resources. In another embodiment (FIG. 2) the UE deactivates one or more contexts and sends an extended service request which identifies one or more context which remains active after the deactivating. In another embodiment (FIG. 3), after the signaling to establish the emergency service (SERVICE REQUEST) the UE sends a deactivation message explicitly indicating which context(s) is/are deactivated (PDN CONTEXT DEACTIVATION or PDN DISCONNECT REQUEST).Type: GrantFiled: November 30, 2011Date of Patent: July 2, 2013Assignee: Renesas Mobile CorporationInventors: Hannu P.
