Abstract
A first network node (20N) in a first communication network (20) transmits information to a second network node (10N) in a second communication network (10). The information indicates a third communication network (30) is in a control signaling path (15) between a communication device (2) and the second communication network (10). In some embodiments, the first network node (20N) and/or the second network node (10N) may apply one or more policies based on the information, e.g., whether to authenticate a subscription of the communication device (2) to the second communication network (10).
Claims15
A method performed by a first network node in a first communication network, the method comprising:
- receiving control signaling from a third network node in a third communication network, the third communication network being a visited public land mobile network (VPLMN);
- based on receiving the control signaling from the third network node in the third communication network, transmitting control signaling to a second network node in a second communication network, the second communication network being a non-public network (NPN);
- transmitting, to the second network node in the second communication network, information that indicates the third communication network is in a control signaling path between a communication device and the second communication network,
- wherein the first communication network is a home public land mobile network (HPLMN) of the communication device;
- wherein the information is transmitted to the second network node in association with transmitting the control signaling to the second network node;
- and
- wherein the control signaling transmitted to the second network node is an authentication request requesting authentication of a subscription of the communication device to the second communication network.
A method performed by a second network node in a second communication network, the second communication network being a non-public network (NPN), the method comprising:
- receiving, from a first network node in a first communication network, the first communication network being a home public land mobile network (HPLMN), information that indicates a third communication network, the third communication network being a visited public land mobile network (VPLMN), is in a control signaling path between a communication device and the second communication network,
- wherein the information is received in association with receiving control signaling from the first network node, the control signaling including an authentication request requesting authentication of a subscription of the communication device to the second communication network.
A first network node configured for use in a first communication network, the first network node comprising:
- communication circuitry;
- and
- processing circuitry configured to:
- receive control signaling from a third network node in a third communication network, the third communication network being a visited public land mobile network (VPLMN);
- based on receiving the control signaling from the third network node in the third communication network, transmit control signaling to a second network node in a second communication network, the second communication network being a non-public network (NPN);
- transmit, to the second network node in the second communication network, information that indicates the third communication network is in a control signaling path between a communication device and the second communication network,
- wherein the first communication network is a home public land mobile network (HPLMN) of the communication device;
- wherein the information is transmitted to the second network node in association with transmitting the control signaling to the second network node;
- and
- wherein the control signaling transmitted to the second network node is an authentication request requesting authentication of a subscription of the communication device to the second communication network.
A second network node in a second communication network, the second communication network being a non-public network (NPN), the second network node comprising:
- communication circuitry;
- and
- processing circuitry configured to receive, from a first network node in a first communication network, the first communication network being a home public land mobile network (HPLMN), information that indicates a third communication network, the third communication network being a visited public land mobile network (VPLMN), is in a control signaling path between a communication device and the second wireless communication network,
- wherein the information is received in association with receiving control signaling from the first network node, the control signaling including an authentication request requesting authentication of a subscription of the communication device to the second communication network.
