Patent number: 9301158Abstract: Methods, devices, and computer program products for optimization of branch synchronization node determination in a peer-to-peer network are disclosed herein. In one aspect, a higher-level node, such as a root node broadcasting master clock synchronization messages to other devices, may determine a dynamic signal strength threshold and send it in those synchronization messages. This dynamic threshold may be determined to ensure that at least a certain percentage of receiving nodes are potential branch nodes, based on the received signal strengths of those nodes at the root node. This method can reduce device energy consumption by only requiring edge devices to relay the synchronization messages, and they can be dynamically identified based on the threshold. In addition, a branch node can also use the dynamic signal strength threshold to help the determination of its potential next-hop branch nodes.Type: GrantFiled: March 7, 2013Date of Patent: March 29, 2016Assignee: Qualcomm IncorporatedInventors: Yan Zhou, Santosh Paul Abraham, George Cherian

Patent number: 9301079Abstract: The present solution relates to providing a call service in a communication system, where in response to recognizing a predetermined event related to a user terminal (UEA), it is checked (203, 204) whether the user terminal (UEA) is a roaming user terminal (UEA) roaming in a visited packet switched network. It is also checked (203, 204) whether the user terminal (UEA) is defined to use a home network routing function in the visited packet switched network. If the user terminal (UEA) is a roaming user terminal (UEA) roaming in the visited packet switched network and defined to use the home network routing function in the visited packet switched network, the home network routing function is over overridden by performing (209) a forced setup of the call service to a local circuit switched network.Type: GrantFiled: October 19, 2011Date of Patent: March 29, 2016Assignee: TELIASONERA ABInventor: Tero Jalkanen

Patent number: 9301271Abstract: The present disclosure relates to the technical field of LTE-A, and discloses a method for air interface synchronization between base stations. A base station to be synchronized, which simultaneously monitors a plurality of neighboring base stations, can select one neighboring base station to perform time-service synchronization in accordance with different criteria in order, such as whether CoMP is necessary, the time-service hop count, time-service delay, and the CQI level (channel quality indicator) and the like. That is, the most suitable synchronization source is determined according to a certain priority order. Such solution both applies to a phase of initial establishment of air interface self-synchronization between base stations, and also to a phase of periodic synchronization maintenance. In addition, the technical effect of such solution is particularly prominent in the case of intensively arranged Small Cells.Type: GrantFiled: August 4, 2014Date of Patent: March 29, 2016Assignees: Beijing University of Posts and Telecommunications, Wuxi BUPT Sensing Technology and Business Research Institute Company LimitedInventors: Qimei Cui, Xiaofeng Tao, Liang Zeng, Yingni Zhang, Ningyu Chen
