Mobile switching node and mobility management node to page terminal device

A method for a mobility management node to page a terminal device in a group of terminal devices associated with a common subscriber number, the comprising:

• receive, by the mobility management node, device capability information for the terminal device;
• determining, by the mobility management node based on the received device capability information, that the terminal device supports a circuit switching call function;
• sending, to a mobile switching node responsive to the determining, an indication that the terminal device supports a circuit switching call function to enable selection of the terminal device by the mobile switching node from the group of terminal devices for a paging request associated with the circuit switching call function;
• receiving, from the mobility switching node following the sending, a circuit switching paging request for the terminal device;
• and
• paging the terminal device.

A mobile switching node device to page a terminal device in a group of terminal devices associated with a common subscriber, the mobile switching node comprising:

• processing circuitry;
• memory containing instructions executable by the processing circuitry whereby the mobile switching node device is operative to:
• receive, from a mobile management node, an indication that the terminal device supports a circuit switching call function;
• store the indication;
• receive a request to implement the circuit switching call function in regard to a subscriber number associated with the group of terminal devices;
• select, responsive to the request, the terminal device from the group of terminal devices associated with the common subscriber number based on the indication;
• and
• send, to the mobility management node responsive to the request, a circuit switching paging request for the terminal device.
