Abstract: This application provides a cache decision method and apparatus. The method includes: receiving, by a policy control function PCF, first cache information sent by at least one local analytic function LAF. The first cache information includes a base station identifier, identifiers of first N1 pieces of application information that are accessed for a maximum quantity of times, and content corresponding to the identifiers of the N1 pieces of application information, where N1 is a positive integer. The method further includes determining, by the PCF, local cache content based on the first cache information and a capacity of a local cache. In this way, the cache hit rate can be effectively improved, transmission bandwidth and data transmission overheads can be greatly reduced, and users' experience improved.

Abstract: A mobile edge computing method and apparatus are provided. The method which is implemented by a mobile edge computing (MEC) management network element includes: receiving an MEC virtualization resource request sent by a control plane of a target radio access network (RAN), wherein the control plane belongs to the target RAN to which user equipment (UE) is handed over, and the MEC virtualization resource request includes an MEC computing resource requirement of the UE; creating, based on the MEC virtualization resource request, a new virtual machine (VM) on an MEC server for the UE, wherein the new VM is used on the target RAN side after the handover; and sending first information of the new VM to the control plane, wherein the first information includes an ID of the new VM. According to the application, the efficiency of usage of resources during a handover of UE is significantly improved.

Abstract: Embodiments of the present invention disclose a data packet processing method and apparatus, and a device. The method includes: if a first data packet is received, determining a first cache queue that is in the first buffer and that is used to store the first data packet; buffering the first data packet in the second buffer if a state of the first cache queue is an invalid state, where a data amount of the first data packet is less than the capacity of the second buffer, and the state of the first cache queue is set to the invalid state when a current data amount of the first buffer reaches the capacity of the first buffer; and if a data amount of the second buffer reaches the capacity of the second buffer, sending all data packets that are in the second buffer to a control plane device.
