For example, when information marketing promotion related to a fifth generation mobile communication technology (5th generation wireless systems, 5G) is performed to a user, whether the user terminal supports 5G or not may be identified by the PCRF, so that promotion information and the like are only sent to the user terminal supporting 5G;

Specifically, in the embodiment of the present invention, message transmission is performed between the MME and the SAEGW through the S11 interface, and in order to transmit the network capability information of the ue to the SAEGW, it is necessary to improve the interface message that the MME sends to the SAEGW through the S11 interface, that is, add a cell for carrying the network capability information of the ue in the interface message, so that when the network capability information needs to be transmitted, the network capability information only needs to be carried in the cell added in the interface message, and is then sent to the SAEGW in the interface message;

optionally, in a specific embodiment, the network capability information of the ue may change each time the ue performs network attachment, so that the ue reports the latest network capability information to the MME each time the ue performs network attachment; in order to send the network capability information of the user equipment to the SAEGW, the MME adds an information element in a Create Session Request (CSR) message in advance, carries the network capability information of the user equipment in the information element added in the CSR message, and sends the network capability information of the user equipment to the SAEGW.

It should be noted that, in the embodiment of the present invention, the network capability information reported by the ue may be Mobile Station (MS) network capability information; or User Equipment (UE) network capability information; or, the network capability information includes both MS network capability information and UE network capability information; specifically, the CSR message may include one cell for carrying the network capability information of the target UE, that is, the MS network capability information and the UE network capability information are carried in one cell; certainly, there may be two cells added in the CSR message for carrying the network capability information of the target UE, that is, one cell is used for carrying the MS network capability information, and one cell is used for carrying the UE network capability information;

Certainly, in specific implementation, whether the SAEGW reports the received network capability information to the PCRF depends on whether the SAEGW receives a network capability change reporting event triggering instruction issued by the PCRF, where the network capability change reporting event triggering instruction is used for triggering the SAEGW to report the network capability change information of the target user equipment to the PCRF.

In specific implementation, after the SAEGW acquires current network capability information of target user equipment after change, whether a network capability change reporting event trigger instruction issued by the PCRF is received or not is detected, and if the detection result indicates that the SAEGW receives the network capability change reporting event trigger instruction issued by the PCRF, the acquired current network capability information of the target user equipment is reported to the PCRF;
