Publication number: 20160302110Abstract: A device for facilitating cellular-wireless local area network (WLAN) interworking may include at least one processor circuit. The processor circuit may be configured to receive a packet including a first tunnel identifier and addressed to a user equipment (UE). The processor circuit may be configured to identify a radio bearer associated with the first tunnel identifier, where the radio bearer is configured to facilitate transmission of the packet to the UE via cellular communications. The processor circuit may be configured to determine whether the radio bearer has been offloaded over a WLAN. The processor circuit may be configured to, when the radio bearer has been offloaded over the WLAN, identify a second tunnel identifier mapped to the radio bearer; encapsulate the packet based on the second tunnel identifier, where the encapsulated packet includes the second tunnel identifier; and transmit the encapsulated packet to the UE over the WLAN.Type: ApplicationFiled: April 7, 2016Publication date: October 13, 2016Inventors: Florin BABOESCU, Petrea TIMARIU, Vinko ERCEG

Publication number: 20150334622Abstract: Systems and methods are disclosed to provide offloading procedures that reduce signaling load. Specifically, embodiments of the present disclosure provide offloading techniques that enable signaling overhead caused by attachment procedures to be avoided when user equipment (UE) reconnects to a cellular network after offloading data to a Wireless Local Area Network (WLAN). According to an embodiment, at least one Public Data Network (PDN) is kept connected through the cellular network access when other PDN connections are offloaded to WLAN. According to another embodiment, a PDN connection through cellular network access is suspended, rather than detached, when data is offloaded to WLAN.Type: ApplicationFiled: May 18, 2015Publication date: November 19, 2015Applicant: Broadcom CorporationInventors: Florin BABOESCU, Dutt KALAPATAPU, Kamesh MEDAPALLI, Hannu HIETALAHTI, Shao-Cheng WANG

Publication number: 20150289185Abstract: A communication device and method for offloading communications from a first communication network to a second communication network. The offloading decision can be based on one or more utility values and/or one or more utility sum values. The utility values and/or utility sum values can be defined in a communication framework. The communication framework can be, for example, Access Network Discovery and Selection Function (ANDSF) framework. The offloading of communication can be from a Long-term Evolution (LTE) network to a wireless local area network (WLAN), or vice-versa. The communication framework can include, for example, utility, utility sum, positional, movement, signal quality, connection duration, data rate, and/or quality of service (QoS) parameters.Type: ApplicationFiled: April 4, 2014Publication date: October 8, 2015Applicant: Broadcom CorporationInventors: Dutt Kalapatapu, Florin Baboescu, Kamesh Medapalli, Farouk Belghoul, Ahmad Rahmati

Publication number: 20150271705Abstract: Systems and methods are provided for determining precedence between Radio Access Network (RAN) rules and Access Network Discovery and Selection Function (ANDSF) rules when a mobile communication device has access to more than one set of rules for offloading data. Systems and methods for transmitting an offloadable Access Point Name (APN) to a mobile communication device when RAN rules are used. Embodiments of the present disclosure combine the advantages of signaling methods when offloading information to a mobile communication device after a RAN rule has been satisfied such that a base station is able to broadcast a signal that enables all devices camped on an serving cell to offload to the APN.Type: ApplicationFiled: March 18, 2015Publication date: September 24, 2015Applicant: Broadcom CorporationInventors: Florin BABOESCU, Dutt Kalapatapu, Shao-Cheng Wang, Pavan Nuggehalli, Hannu Hietalahti

Publication number: 20150264587Abstract: A wireless communication device (e.g., generally, a device) includes a communication interface and a processor configured to support communications with one or more other devices. In an example of operation, the device supports first communications based on a first communication protocol with a first network coordinator device and identifies a second network coordinator device that operates based on a second communication protocol when supporting those first communications. The device also determines one or more operational parameters associated with the second network coordinator device. When one or more conditions is/are appropriate, the device interworks the first communications and second communications based on the second communication protocol with the second network coordinator device.Type: ApplicationFiled: February 27, 2015Publication date: September 17, 2015Applicant: BROADCOM CORPORATIONInventors: Matthew James Fischer, Qi Wang, Vinko Erceg, Raymond Reynolds Hayes, Mark Kent, Florin Baboescu, Dutt Harinarayan Kalapatapu
