Claim 0:
1. A system, comprising:
a target user plane function entity; and
a session management function entity comprising:
one or more processors; and
a memory coupled to the one or more processors and configured to store computer-executable instructions that, when executed by the one or more processors, cause the session management function entity to:
select the target user plane function entity to serve a terminal;
send first path information to the target user plane function entity;
send second path information to a source user plane function entity, wherein the first path information and the second path information are for establishing a forwarding path between the target user plane function entity and the source user plane function entity; and
send a second routing rule to the target user plane function entity,
wherein the second routing rule specifies that data whose destination address is of a second application server (AS) is to be sent to the source user plane function entity, which is communicatively connected to the second AS, and
wherein the target user plane function entity is configured to receive the second routing rule from the session management function entity.
