Abstract
A communication method and apparatus, where the method includes: A first mobility management network element in a first network obtains information about N intermediate session management network elements that are capable of serving a terminal in the first network, and determines that a combined intermediate session management network element (which is capable of providing session management in the first network and in a second network) in the N intermediate session management network elements is a first intermediate session management network element corresponding to a first session of the terminal in the first network, such that overall communication efficiency of the network is improved. For example, network address resources are reduced to simplify network planning and deployment complexity, a quantity of nodes in the network is reduced to simplify network operation and maintenance workload, and signaling between the nodes in the network is reduced to reduce network service load.
