A method is disclosed providing data transmission for a mobile receiver in a publish / subscribe system. The method comprises: 1) handover trigger: detecting a new access router AR2 by a mobile receiver in the publish / subscribe system; and sending a handover trigger message comprising AR2 identification information from the mobile receiver to a router AR1 currently connected to the mobile receiver; 2) handover preparation: receiving the handover trigger message by the AR1; selecting a branch node of the most recent position before handover as a proxy for the mobile receiver; and forwarding data packets to paths of the mobile receiver before and after handover; and 3) handover execution: handover access router of the mobile receiver to AR2 by the proxy; after the step of handover access router, triggering AR2 and AR1 to update data transfer for the mobile receiver; sending the data packets through the AR2 to the mobile receiver. The present invention has high handover performance, and can reduce handover time delay and data packet loss.

The embodiment of the present invention discloses a method and device for triggering protection switching due to signal degradation of a link aggregation port, wherein the method includes: acquiring the member port status information of the link aggregation port from the status register of the link aggregation port; The member port status information of the link aggregation port is obtained to obtain the quantity value X of the signal degradation optical path attenuation in the member port of the link aggregation port; the quantity value X of the signal degradation optical path attenuation in the member port of the link aggregation port is compared with a predetermined threshold; When the number X of signal degradation optical path attenuation in the member ports of the link aggregation port is greater than the predetermined threshold, set the state of all member ports of the link aggregation port to the signal degradation state, and notify the virtual segment layer to report the fault and perform service protection switching On the backup link, the Ethernet service egress is realized when the SD optical failure occurs on the link aggregation port to realize the protection switching and switching back of the service, ensuring the switching performance of the carrier level.

The embodiment of the invention relates to a wireless communication technology, in particular to a survey information configuration method and system and a base station, which are used for solving the problem that a network side in the prior art can not carry out correct survey configuration on an HeNB (Home enhanced Node B) with a changed frequency point so that the inbound handover property is influenced. The method provided by the embodiment of the invention comprises the following steps: the base station determines frequency points, corresponding to an ECGI (E-UTRAN (Evolved Universal Terrestrial Radio Access Network) Cell Global Identifier), from a user terminal on the basis of the corresponding relationship between an updated ECGI and the frequency points, wherein the corresponding relationship between the updated ECGI and the frequency points is that the ECGI corresponds to the current frequency point of a femtocell; and the base station searches frequency points of the survey information which are not configured for the user terminal, from the determined frequency points and configures the survey information of the searched frequency points for the user terminal. By adopting the method provided by the embodiment of the invention, the accuracy of survey configuration for the HeNB with a changed frequency point can be improved, and the property of UE (User Equipment) forcarrying out inbound handover can be guaranteed.

The invention relates to a route protection converting method and device. The route protection converting method comprises the following steps of: configuring a three-layer virtual interface bound with a two-layer VPN (Virtual Private Network) on device nodes of two ends of the two-layer VPN; establishing a protection group relation between a protection route and a protected route according to the binding relation of the two-layer VPN and the three-layer virtual interface; and converting a link flow rate from the protected route to the protection route through the three-layer virtual interface according to the protection group relation when a protected link has failure. According to the route protection converting method disclosed by the invention, through the three-layer virtual interface ARP (Address Resolution Protocol) protection policy, without changing an original network topology and two / three-layer domain partition, the protection of an over two-layer network domain on a three-layer network domain route is realized, a problem of flow interruption of the three-layer route at the two / three-layer network connection caused by DOWN (Direct Memory Access Controller) is solved, and additional devices and a hardware lookup operation do not need to be additionally arranged; and in addition, the expandability of a network structure is improved, the network complexity is reduced and the maintenance cost is saved when conversion performances are ensured.

The invention belongs to the technical field of link backup, and in particular relates to a link backup system and control method and system of a multicast video code stream, aiming to solve the problem that the existing backup technology will increase the number of multicast video codes under the premise of real-time backup switching. streaming or video multicast streaming bandwidth, which leads to the problem of rising costs. The invention includes: the encoding module and the decoding module respectively configure the same multicast address for the network ports of the active and standby links; only send the group adding message and the multicast video heartbeat message, and establish an information forwarding channel; the decoding module according to the code stream The serial number is used to check and discard the code stream message; detect the status of the main and standby links, and determine the switching conditions. If the encoding process meets the conditions, the code stream sending link will be switched; Frames are switched for boundaries. The invention does not increase the cost of the core switch, realizes the link backup of the multicast code stream, and achieves automatic, real-time and seamless video switching effects.

Embodiments of the subject matter described herein provide a reduction mechanism (100) for a switching device and a switching device. The reduction mechanism (100) comprises: a shaft (1) adapted to rotate in response to the operation of an actuator to drive a moving element of the switching device; at least one reduction wheel (2) fixed to the shaft ( 1) with a deceleration profile (6); and a movable rocker (4) which engages the deceleration wheel (2). The reduction wheel (2) is adapted to cause the rocker (4) to move against a reduction profile (6) on the reduction wheel (2) in response to rotation of the shaft (1) in order to decelerate the rotation of the shaft (1). The deceleration mechanism can decelerate the operation of the moving element of the switching device without affecting the switching performance and service life of the switching device.

The invention discloses a method and apparatus for sending identification information and a call switching request. The method for sending the call switching request comprises the following steps: determining that a switched call initiated by UE in a PS domain to a CS domain contains an emergency call; obtaining the identification information of an anchored EATF when the UE initiates the emergency call; and switching the emergency call of the UE in the CS domain according to the identification information. By adoption of the method, the problem that the emergency call may not be switched in the case of multi-service domain networking is solved, and thus the effect of ensuring to switch the emergency call is achieved.
