Abstract: A device translates between a first communication network, in particular a deterministic communication network, and a second communication network, in particular a mobile communication network, in particular a 5G communication network. The device is configured to execute an application function that is configured to translate between Quality-of-Service, QoS, parameters of the first communication network and QoS parameters of the second communication network. A QoS profile includes the QoS parameters of the first communication network translated by the application function and, optionally, additional QoS parameters originating from the second communication network. The device is further configured to execute a signaling procedure configured to exchange the translated QoS parameters within the second communication network.

Abstract: This disclosure provides a communication method, and a corresponding apparatus. In the method, a terminal device obtains association information between first traffic description information and second traffic description information; determines the first traffic description information and the second traffic description information; and sends a first request message and a second request message that include same session pair information to establish redundant sessions. The first request message is used to request to establish a first session corresponding to the first traffic description information and the second request message is used to request to establish the second session corresponding to the second traffic description information.

Abstract: A domain name system query method in which: a first network element receives a DNS query request including a first domain name from a terminal apparatus; the first network element sends first request information which comprises location information of the terminal apparatus and the first domain name to a second network element; the second network element determines, based on the first request information, an IP address and feeds back the IP address to the first network element; and the first network element sends the IP address to the terminal apparatus. When a terminal apparatus performs domain name query, a core network element determines an IP address of an application server based on location information of the terminal apparatus and a queried domain name. In this way, the terminal apparatus obtains an IP address of an application server close to the terminal apparatus, thereby improving service access efficiency of the terminal apparatus.

Abstract: A method and system for enhanced time synchronization with lesser delay and jitter, from a gateway of a network or an external standard time source, over the internet, in a traditional network, including SDN, by NTP clients like newly added devices, spawned VMs and the like, by automatic deployment of the distributed NTP service through DHCP and DNS servers by spawning NTP demons (ntpd), according to the time synchronization requests received, thereby offloading the NTP functionality of the gateway and decreasing NTP traffic.

Abstract: This application discloses a path processing method, an apparatus, and a related computer-readable storage medium. In the method, whether there is an existing communication connection for a service flow is determined, and a service feature indicator corresponding to the existing communication connection satisfies a service feature condition required by the service flow. In a case of determining that there is the existing communication connection, a service packet is sent in the existing communication connection. In a case of determining that there is no existing communication connection, a new communication connection is established for the service flow, and a service packet is sent in the new communication connection, and a service feature indicator corresponding to the new communication connection satisfies the service feature condition required by the service flow.

Abstract: Embodiments of the present disclosure disclose a service processing method, an apparatus, and a system that relate to the field of communications technologies and are used to reduce resource waste. The method includes: controlling, by a controller, a first node to send a received packet to a processing network; and controlling, by the controller, the processing network to process the packet and then send a processed packet to a second node. The first node is a base station or a network element connected to the base station, and the second node is a routing function entity; or the first node is the routing function entity, and the second node is the base station or a network element connected to the base station. The routing function entity is an anchor point of an Internet Protocol IP address of a user.
