An information processing method, the method comprising: receiving, by a session management function, SMF, a notification message sent by an access and mobility management function, AMF, wherein the notification message is used for indicating that a user equipment, UE, has moved to a service coverage of a first PDU session anchor connected to a multi-access edge computing, MEC, server; sending, by the SMF, a session modification indication message to an uplink classifier, wherein the session modification indication message is used for indicating inserting the uplink classifier into a session link; obtaining, by the SMF, first address information of a local domain name system, DNS, server, wherein the first address information is an Internet Protocol, IP, address of the local DNS server; and sending, by the SMF, the first address information to the uplink classifier, and sending, by the SMF, through the AMF, the first address information to the UE, wherein the first address information is used for the UE to refresh cached address information as the first address information; wherein the method further comprises: sending, by the SMF, a traffic routing rule to the uplink classifier, wherein the traffic routing rule is used for configuring the uplink classifier to route, according to the first address information, through the first PDU session anchor, first data of the UE corresponding to a local position to the local DNS server, wherein the first data of the UE corresponding to the local position is data sent by the UE within the service coverage of the first PDU session anchor connected to the MEC server. receiving, by a session management function, SMF, a notification message sent by an access and mobility management function, AMF, wherein the notification message is used for indicating that a user equipment, UE, has moved to a service coverage of a first PDU session anchor connected to a multi-access edge computing, MEC, server; sending, by the SMF, a session modification indication message to an uplink classifier, wherein the session modification indication message is used for indicating inserting the uplink classifier into a session link; obtaining, by the SMF, first address information of a local domain name system, DNS, server, wherein the first address information is an Internet Protocol, IP, address of the local DNS server; and sending, by the SMF, the first address information to the uplink classifier, and sending, by the SMF, through the AMF, the first address information to the UE, wherein the first address information is used for the UE to refresh cached address information as the first address information; wherein the method further comprises: sending, by the SMF, a traffic routing rule to the uplink classifier, wherein the traffic routing rule is used for configuring the uplink classifier to route, according to the first address information, through the first PDU session anchor, first data of the UE corresponding to a local position to the local DNS server, wherein the first data of the UE corresponding to the local position is data sent by the UE within the service coverage of the first PDU session anchor connected to the MEC server.
