1. A communication processing method, comprising:
receiving, by a session management function network element, a first application request, wherein the first application request includes a request to provide a service of a 5G virtual network for a first local area network in a data network, and the first application request carries address segment information of the first local area network, information that is about a target group and that corresponds to the first local area network, and interface information of a first tunnel interface of a first local switch in the first local area network;
determining, by the session management function network element, a first user plane function network element that provides the service of the 5G virtual network for the first local area network;
sending, by the session management function network element, first routing information to the first user plane function network element, wherein the first routing information includes a request to the first user plane function network element to forward received first data to the first tunnel interface when a destination address of the first data is any address comprised in the address segment information of the first local area network;
determining, by the session management function network element, a first online device, wherein the first online device is a device that is in the target group and managed by the session management function network element and that has joined the 5G virtual network;
determining, by the session management function network element, a second user plane function network element at which the first online device is anchored; and
sending, by the session management function network element, second routing information to the second user plane function network element, wherein the second routing information includes a request to the second user plane function network element to forward received second data to the first user plane function network element when a destination address of the second data is any address comprised in the address segment information of the first local area network.
