The present invention discloses a method for identifying travel classification based on smartphone travel surveys. The method takes individual volunteers as the object, GPS information collected by smartphones and instant recall verification features of respondents as the data source. First, travel features, individual features, and family features are determined by GPS data and questionnaire information of volunteers. Then, a training data set is determined by the equal proportion method. Finally, an artificial neural network combined with a particle swarm optimization algorithm is used to detect travel classification from the survey data. The method described in the invention can realize automatic identification of six travel classifications. It is conducive to replace the traditional resident travel survey with the advanced survey method under the environment of big data. At the same time, it provides data foundation for urban management and planning.

An octa-electrode linear ion trap mass analyzer is formed by eight cylindrical electrodes and at least two end-cap electrodes. The inside surfaces of the eight cylindrical electrodes are free-form. The material of the octa-electrode linear ion trap mass analyzer is a conductive metal material or an insulating material plated with a conductive coating. The eight cylindrical electrodes are divided into four groups of cylindrical electrodes in total, each group of the four groups of cylindrical electrodes comprises two cylindrical electrodes, and each two groups of the four groups of cylindrical electrodes are parallelly placed. At least one through hole is provided with in the center of the end-cap electrode, and the two end-cap electrodes are respectively arranged at both ends of the cylindrical electrode.

Embodiments of the present disclosure relate to a method for managing user information in a SIP network and a device thereof. The method comprises: initiating a restart timer after a SIP access gateway restarts; within an expiration period of the restart timer, sending a heartbeat reply message to the network element in response to a heartbeat message from a network element, the reply message including the time when the SIP access gateway restarts. If a difference between the time when the SIP access gateway restarts and a current time is less than a time interval between heartbeat messages, the network element sends a registration request to the SIP access gateway, where the registration request includes user information of all users represented by the network element. It is further disclosed a device implementing the method discussed above.

The present invention relates to a method and apparatus in a Media Gateway (MG) for handling disconnection between the MG and a Media Gateway Controller (MGC). Multilevel requirements are fulfilled by setting different timeout periods for a disconnection timer. On the one hand, if the timeout period of the disconnection timer is not equal to zero, new events that occur during the disconnection are stored. Then, after the connection is recovered, the stored new events are reported to the MGC, so that the data and states in the MG can match those in the MGC after the connection recovery. On the other hand, if the timeout period of the disconnection timer is equal to zero, all active calls are immediately released.
