Abstract
A communication method, apparatus, and system, to implement service data transmission in a server localization scenario, where the method includes: A first network element determining a first address used by a user equipment to send a data packet of a first service to a user plane function network element; and the first network element sending, to the user plane function network element, a correspondence between the first address and address information of a first server that provides the first service, where an address indicated by the address information is used by the user plane function network element to send the data packet to the first server.
Claims20
A communication method, comprising:
- determining, by a first network element, a first address used by a user equipment to send a data packet of a first service to a user plane function network element;
- sending, by the first network element to the user plane function network element, a correspondence between the first address and address information of a first server that provides the first service, wherein the address information indicates an address used by the user plane function network element to send the data packet to the first server;
- obtaining, by the user plane function network element, the correspondence from the first network element;
- receiving, by the user plane function network element, a second address from the user equipment, wherein the second address is the same as the first address;
- and
- determining, by the user plane function network element based on the second address and the correspondence, a second server that provides the first service for the user equipment, wherein the first server comprises the second server.
A communication system, comprising:
- a first network element configured to:
- determine a first address used by a user equipment to send a data packet of a first service;
- and
- send a correspondence between the first address and address information of a first server that provides the first service;
- and
- a user plane function network element configured to:
- send, using an address indicated by the address information, the data packet of the first service to the first server;
- obtain the correspondence from the first network element;
- receive a second address from the user equipment, wherein the second address is the same as the first address;
- and
- determine, based on the second address and the correspondence, a second server that provides the first service for the user equipment, wherein the first server comprises the second server.
