Abstract: A method and an apparatus for non-access stratum (NAS) message processing during handover in an evolved network are provided. The method includes the following steps. An evolved packet core (EPC) receives a message which indicates that a UE is being handed over sent by a source evolved NodeB (S-eNB), and stops sending an NAS message to the UE temporarily. The EPC receives a message which indicates that the UE returns to an S-eNB service area sent by the S-eNB. The EPC sends the NAS message to the UE through the S-eNB, if needed. With the method and the apparatus, the EPC can acquire a location of the UE in time in the case of a handover failure of the UE, a time limit of a retransmission timer is set precisely, and a specific implementation for forwarding an NAS message through an X2 interface is provided.

Abstract: A communication method and an apparatus are provided in embodiments of this application. When a cell served by a DU of an access network device and a neighboring cell use different timing, the DU may obtain timing configurations of a first cell and a second cell, or a RACH configuration that is of a second cell and that is based on timing of a first cell. When the method is applied to a RACH optimization scenario, the DU may determine, at same timing, RACH configurations of the two cells based on the foregoing obtained information, to accurately identify whether a RACH configuration conflict occurs between the cell and the neighboring cell, optimize the RACH configuration of the cell when the conflict occurs, and ensure a success rate and an access latency of random access performed by a terminal device.

Abstract: Example multi-connectivity communication methods and apparatus are described. In one example method, an access network device of a first network determines to use an access network device of a second network to perform data splitting for data of UE. Then, the access network device of the first network sends first splitting configuration information to the UE and sends second splitting configuration information to the access network device of the second network. The first splitting configuration information is used to notify the UE that the access network device of the second network is to split to-be-split data of the UE. The second splitting configuration information is used to instruct the access network device of the second network to split the to-be-split data of the UE.
