摘要： A network router is tested for operation according to a given network protocol, by coupling the router under test (RUT) to a test host device and arranging the device to simulate operative test network topologies which include router nodes, network nodes, and edges between the nodes. The device exchanges information packets with the RUT for each of a number of successive test network topologies. Each successive topology is determined randomly by inserting or deleting an edge or a node to or from a prior test network topology in a probabilistic manner. Operation of the RUT under the given protocol is evaluated based on the exchanged information packets. A judgment, e.g., a fault or a no-fault condition, is rendered by the host device.

摘要： A method of generating a set of test sequences for evaluating interoperability of a number of interconnected communication systems with respect to a desired mode of communication between a first end user and a second end user. A number of operational states that are required of the communication systems to implement the desired mode of operation between the two end users is determined, wherein each state pertains to a first operation of a first gateway system associated with the first end user and a corresponding second operation of a second gateway system associated with the second end user. The interconnected communication systems are tested by causing the systems to perform specified transitions between pairs of at least some of the operational states.

摘要： The present invention relates to a method for handover of a mobile terminal from a first network to a second network, a network element, a mobile terminal, a base station and a communications system as well as a computer program product and a storage medium. The method comprises the steps of: determining a WDP including an unnecessary handover probability and a missing handover probability according to conditions of the first network and the second network; detecting at least of the following: whether the unnecessary handover probability is greater than the missing handover probability, whether the unnecessary handover probability is greater than a specific threshold and whether the missing handover probability is smaller than a specific threshold; and making a handover decision based on the detection result. The present invention can select a more suitable target network for handover at a more suitable time, thus ensuring the continuity of a mobile user's call.

摘要： A user subscribes to desired information in an RSS gateway, and the RSS gateway aggregates the subscription requests from users before subscribing to requested multimedia content. The RSS gateway aggregates subscription requests from a plurality of users and subscribes to the requested RSS feeds on behalf of the users. The RSS gateway also receives RSS feeds from content servers and RSS web-sites and sends the received RSS feeds to subscribing users using SIP.
