Abstract: A method for carrying out data integrity protection on a communication network. According to an implementation, a wireless communication device indicates, to a wireless network, the maximum data rate up to which integrity protection is supported for user plane data. A network node (e.g., a node of the core network, such as an SMF) receives this information and determines whether or not to enable integrity protection for user plane data based on the information (possibly in conjunction with other information such as the minimum data rate to be supported, etc.). The network node then communicates the decision to enable or disable integrity protection to a RAN node (e.g., a wireless base station).

Abstract: Provided is a data packet transmission method and device. The method includes: generating, by a first network element, first indication information according to a delivery status fed back by a second network element to the first network element, where the first indication information is used for instructing the second network element which has not successfully sent a data packet to a terminal to discard the data packet indicated by the first indication information. The present disclosure may solve the problem in the related art of unsynchronized data transmission in sending of a data packet to a terminal by a plurality of second network elements.

Abstract: Provided are an optimized processing method and apparatus for service migration of a terminal. According to the optimized processing method, when the terminal conducts service transmission with a network or when the terminal performs service migration between a source network element and a target network element, service performance information of the terminal is acquired. By means of the technical solution, the technical problem in the related art that the service performance or service experience, etc. of a terminal is not taken into account during service transmission between a terminal and a network or during service migration of a terminal is solved, so the service performance and service experience can be obtained when the terminal conducts service transmission or service migration, thereby providing a powerful support for optimizing the service migration or service transmission of the terminal and improving the experience of a user.

Abstract: The disclosure discloses an authentication method and system for a wireless mesh network. The method comprises: when a new node accesses a network and the node is a Mesh Point (MP), the MP selects one authenticated node from neighbor nodes as a father node, and a uniquely identified secure path exists between the father node and an AC; the MP uses the father node as an authentication point to perform authentication; and after being transmitted to the AC through the secure path between the father node and the AC, which then forwards an authentication message to an AS; similarly, a return message of the AS is forwarded by the AC to the father node through the secure path, and the MP is authenticated. The authentication message is saved on the AC at the same time, so as to facilitate the second authentication of the MP.

Abstract: Disclosed is a method and system for establishing a transmission channel in a fusion networking system. The method includes that an access side network element of a 3rd Generation Partnership Project (3GPP) system acquires Internet Protocol (IP) address information and/or port number information used when a Wireless Local Area Network (WLAN) system network element establishes an XW interface, and initiates an establishment flow of a transmission channel of the XW interface with the WLAN system network element according to the IP address information and/or the port number information.

Abstract: User equipment may request to communicate with a basestation over a contention-based wireless communication channel. The basestation and the user equipment may perform a multiple-step random access protocol to determine whether the user equipment may communicate over the wireless communication channel. The architecture, e.g., the fields and structure of the messages sent by the basestation may indicate the content and type of those same messages.
