  • Patent number: 9301158
    Abstract: 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.

  • Patent number: 9301079
    Abstract: 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.

  • Patent number: 9300519
    Abstract: A method and apparatus is provided for communication between a first terminal capable of using both a Circuit Switched (CS) call and an Internet Protocol Multimedia Subsystem (IMS) session, and a second terminal capable of using the IMS session, in a communication system supporting a Combined CS call and IMS session (CSI service). If the second terminal sends a Session Initiation Protocol (SIP) request (INVITE) message to originate a voice service or a multimedia service including the voice service with the first terminal, a CSI Application Server (AS) of an IMS domain managing the first terminal separates a voice service-related component included in the request message from a multimedia service-related component, and generates and sends first and second request messages to the first terminal.

  • Patent number: 9301271
    Abstract: 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.

  • Patent number: 9300581
    Abstract: In embodiments of mesh network addressing for duplicate address detection, an end device of the mesh network can generate an address identifier that includes an address and time-based information associated with the end device, which is attached to a router device for communication in the mesh network. The address identifier is maintained by the router device as a tuple state of the end device. The end device or the router device can initiate an address query requesting that mesh network devices in the mesh network having a designated address respond with the tuple state that corresponds to the designated address. The end device or router device receives the tuple state of mesh network devices having the designated address in response to the address query, and can then detect a duplicate address of a mesh network device based on the time based information.
