Publication number: 20140295831Abstract: A wireless communication device includes a single baseband processor and RF chain for servicing a first and second SIM. Each of the SIMs connects to a different network, and one may be used for one data type while the other is used for another data type. In order to track the connectivity of an inactive first SIM, a controller periodically interrupts service to the second SIM. During its connection, the first SIM monitors the connection to its network. A triggering mechanism and trigger threshold define when a switch to a new cell is needed. The device receives the mechanism and threshold from the network and calculates a modified threshold and/or mechanism is order to reduce a number of potentially missed calls.Type: ApplicationFiled: March 29, 2013Publication date: October 2, 2014Applicant: Broadcom CorporationInventors: Navin KARRA, Yongqian WANG, Lianghua YANG, Shiwen CHEN, Naveen Reddy PALLE VENKATA, Yuan LIU, Jun LIN, Yaxin CAO, Augustine SHUTON, Balaji ANANDAPADMANABAN

Publication number: 20070195728Abstract: A method is provided for mobile wireless ad hoc network, where network nodes using the same routing protocol are uniformly sharing a single contention channel. Network nodes are able to dynamically and distributedly switch roles according to surrounding network environment so that routing functions can be either activated or de-activated in order to improve routing efficiency and increase network capacity by reducing unnecessary routing overhead (which is caused by excessive redundant routing nodes). In addition, the nodes are able to self organize themselves into hierarchies or different roles according to different routing strategies. The proposed role-switching method can be implemented on network nodes which support existing routing protocols or native routing protocol proposed herein to further exploit the proposed role-switching method.Type: ApplicationFiled: February 17, 2006Publication date: August 23, 2007Inventors: Shiwen Chen, Hongbing Li, King Huang, Harumine Yoshiba, Kou Chu Lee, Jingxuan Liu

Patent number: 7237260Abstract: Distributed modules in a network dynamically select communication protocols to communicate in a secure or firewall-protected network. Applications register with a lookup service. The lookup service maintains a lookup table including registration information for multiple applications. Registration information may include, but is not limited to, IP address, firewall restrictions, tunnel protocol, port information, and proxy queue capabilities. An application seeking to communicate acquires the registration information for a desired recipient from the lookup table. The application uses the registration information to select communication protocols necessary to communicate with the recipient.Type: GrantFiled: July 8, 2003Date of Patent: June 26, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Juan Yu, Hasan Timucin Ozdemir, Kuo Chu Lee, Shiwen Chen, Eimei Nanma
