Fig. 1 is a flow chart of a roaming control method according to an embodiment, as shown in fig. 1, where the method provided in this embodiment is applicable to a core network device (e.g. UDM device), and the method includes the following steps.
S110, the first communication node receives a first message sent by the second communication node, where the first message includes a public land mobile network identity (Public Land Mobile Network Identity, PLMNID).
The first message is a message initiated by the terminal device and sent to the second communication node, and the second communication node forwards the first message to the first communication node after receiving the first message sent by the terminal device.

And S220, the UDM equipment confirms whether a roaming control scheme matched with the terminal equipment is included in the second roaming sub-template according to the PLMNID.
A roaming template can be signed up at the same time in the terminal equipment, and the template identifier of the roaming template signed up at the current moment of the terminal equipment is assumed to be 1. The roaming template may include a first roaming sub-template and a second roaming sub-template, the roaming template being adapted for network level roaming control granularity. The first roam sub-template may be as shown in table 1 below and the second roam sub-template may be as shown in table 2 below.
TABLE 1

For example, in the gui information, plmnid=46003, amfid=0a0282, and the udm device may parse to obtain amframe=10 and amfset=2 according to amfid=0a0282.
