Abstract: Embodiments of the present disclosure relate to the field of communications technologies, and provide a packet transmission method, an apparatus, and a packet transmission system, so that an uplink packet can be successfully transmitted to a corresponding forwarding device without requiring user equipment to add information about the forwarding device to the packet, thereby improving utilization of an air interface resource in a small data service. The method includes: receiving, by an access network node, an uplink packet from user equipment, where the uplink packet includes first index information, and the first index information is used to search for a first forwarding device that is to forward the uplink packet; determining, by the access network node, the first forwarding device corresponding to the first index information; and sending the uplink packet to the first forwarding device.

Abstract: A communication method and a related apparatus are provided. The method includes: after determining that the cell accessed by the terminal device is a cell of the mobile relay, a first access network device proactively reports current location information of the mobile relay to the core network device serving the terminal device, so that the core network device determines the location information of the terminal device based on the location information of the mobile relay. This resolves a problem that cell information of the mobile relay may not match an actual geographical location of the terminal device.

Abstract: An authorization method and an apparatus are provided. An access management network element obtains operation allowed indication information and an authorization condition, where the operation allowed indication information indicates that a terminal device is allowed to provide a connection service, and the authorization condition includes an authorized location range of the connection service and/or an authorized time range of the connection service. The access management network element determines an authorization result based on the authorized location range and/or the authorized time range, and sends the authorization result to an access network element accessed by the terminal device, where the authorization result indicates that the terminal device is not allowed to provide the connection service, or the terminal device is allowed to provide the connection service.

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: Embodiments of this application provide a slice information processing method and apparatus to preferentially allocate a network slice resource to a slice for which a slice service level agreement SLA has been signed. An example solution includes: An access network device determines that a slice service level agreement (SLA) has been signed for a first slice and that no slice SLA has been signed for a second slice. The access network device prioritizes a user behavior action of the first slice, or deprioritizes a user behavior action of the second slice.
