The present invention provides a method and device for processing NAS messages when NAS COUNT is reversed, wherein the method includes: the MME and the UE perform the first authentication and key negotiation authentication process AKA1, and when AKA1 is successful , the MME establishes the first security context KASME1 for message interaction with the UE; when the NAS COUNT reaches the preset rollover threshold, the MME uses the first security context KASME1 to conduct a second authentication with the UE The right and key agreement authentication process AKA2; if the AKA2 fails, the MME does not use the KASME1 to perform the third authentication and key agreement AKA3 authentication process with the UE; when the AKA3 succeeds, the MME A second security context KASME2 for message exchange with the UE is established. The present invention greatly improves the user's perception experience, greatly reduces the signaling message interaction between the UE and the network side, saves wireless air interface resources between the UE and the wireless side, and effectively reduces the impact on the LTE network.

The invention is suitable for the technical field of mobile terminals, and provides a system and a method for automatic rebooting subsequent to the crash of a Modem of a smart phone. The system comprises a battery, a switch circuit, a wireless communication module for the modem and an intelligent operating system application processor, wherein the wireless communication module for the Modem and the intelligent operating system application processor perform information interaction on each other; the Modem is powered off by disconnecting the switch circuit when the Modem crashes; the switch circuit is on after the powered-off Modem discharges and resets, and the battery is restored to supply power to the wireless communication module for the Modem. By adding the switch circuit in the system, the Modem is enabled to automatically restore to a normal working state without pulling and inserting the battery by a user after the Modem crashes, so that the user has no sense of the crash of theModem, the experience of the user can be improved, furthermore, the added switch circuit is simple and cheap, therefore, market prospect is wide.

An advertisement publishing system based on virtual reality technology disclosed in the present invention includes: at least one virtual advertisement scene experience unit, which is used to test the received virtual advertisement in the virtual reality application scene built therein. display, and provide users with an experience service of browsing virtual advertisements from a first-person perspective; a cloud server, which establishes a communication connection with each virtual advertisement scene experience unit; and a virtual advertisement management platform, which communicates with the virtual advertisement management platform The cloud server establishes a communication connection, and the virtual advertisement management platform produces virtual advertisements according to user requirements, and performs unified management and release of the prepared virtual advertisements. An advertisement distribution method is also disclosed. The beneficial effect of the present invention is that: the present invention can implant advertisements in the virtual reality experience scene, allowing users to perceive from a first-person perspective, and enhancing the user's experience perception in various aspects.

The present application relates to the field of communications, and in particular to a method and device for processing abnormalities in service tunnels, which are used to avoid excessive occupation of network resources when detecting abnormalities in service tunnels on the user plane. The method is: when the base station determines that the service tunnel of the user plane is abnormal, instructs the core network to modify the path of the service tunnel through control plane signaling, and after determining that the modification is successful, uses the service tunnel based on the modified path Continue to perform service data transmission with the core network. In this way, the existing 3GPPR15 protocol has been further improved, so that the core network side can be informed of the abnormality of the user plane service plane tunnel in time and perform corresponding processing operations, thereby ensuring the relevant bearer and communication of the terminal on the base station side and the core network side. The state consistency of resources effectively improves the available resources of the core network, and at the same time prevents terminals from excessively occupying network resources.

The present disclosure discloses a method for determining a multimedia message gateway, comprising: receiving a message of querying a multimedia message gateway sent by a value-added service server after the value-added service server generates a multimedia message; acquiring the service processing situation or resource occupation situation of each multimedia message gateway, determining the multimedia message gateway with the strongest service processing capacity currently according to the service processing situation, or determining the multimedia message gateway with the most residual resource according to the resource occupation situation; and using the determined multimedia message gateway as the multimedia message gateway for sending the multimedia message. The disclosure further discloses a method for sending a multimedia message, an apparatus for determining a multimedia message gateway and a system for sending a multimedia message. The disclosure can solve the problem of traffic imbalance of each multimedia message gateway caused by presetting multimedia message gateways in the prior art.

The invention discloses a method and a system for displaying virtual private mobile network (VPMN) user short numbers in a call assistant service. The method comprises the steps: dialing the user short numbers of the call assistant service through a VPMN user; triggering the call to a service control point (SCP) through a calling mobile switching center (MSC), building a connection between calling and called terminals according to the returned calling and called long numbers from the SCP, moreover, carrying out signaling acquisition on the SCP so as to obtain the calling and called long and short numbers, and storing the calling and called long and short numbers in a short number log sheet; and when the called terminal is turned off or cannot transfer the call, transferring the call to the call assistant platform through the calling MSC, and when the called terminal is turned on or returns to a service area, searching the short number log sheet of the call through the call assistant platform, and sending call assistant prompt messages to the calling or called terminal in a short number mode in the short number log sheet. The method belongs to the technical field of network communication; and when the VPMN user calls the call assistant service user through using the short numbers, call assistant prompt messages can be sent to the calling and called terminals in the short number mode.

The invention belongs to the application field of robot education, and provides a story-based robot teaching system for young children, which includes a story map making module, a robot programming teaching module and a robot evaluation module. Through the linkage between the robot programming teaching module and the moving track on the story map, the present invention realizes the integration of abstract concepts into programming games, programming logic and story scenes; aggregation of different blocks on the story map can form different story combinations, interpretations and plots. Interaction mode; the different moving modes of the robot body on the story map can enhance children's perception experience, understand and form abstract concepts such as time, space, number, quantity and geometric figures in the programming process; collect children's learning in the process of robot programming Behavioral data is used to construct the index system, weight assignment and visual expression of evaluation results for children's robot programming ability evaluation.
