Title: METHOD AND DEVICE FOR ESTABLISHING PDU SESSION
Abstract:
A method and device for establishing a PDU session. The method comprises: a terminal determines, according to a roaming policy comprised in a first message, whether local breakout is allowed by a PDU session to be established, and generates a PDU session establishment request; and because the PDU session establishment request comprises first indication information indicating whether the local breakout is allowed by the PDU session to be established, an AMF network element receiving the PDU session establishment request can generate a session management request according to the first indication information, thereby establishing a PDU session of HPLMN or a PDU session of VPLMN. Compared with the prior art in which the PDU session to be established which is identified according to a SM capacitor is required to be home routed, the solution in the present application uses only one SM capacitor without increasing the number of the SM capacitors, thereby effectively avoiding the problem of complicated NAS messages.
