Abstract
A Circuit Switched (CS) domain codec list for Single Radio Voice Call Continuity (SR-VCC) is provided. An apparatus providing such a list can include preparing a list of include preparing a list of circuit switched capabilities of a terminal device, sending the list to a network device during attachment, receiving the list at the network device, storing the list in the network device, sending the list to a second network device, receiving the list at the second network device, and using the list in handing over the terminal device to the second network device.
Claims15
A method, comprising:
- preparing, in a mobile terminal device, a list of circuit switched capabilities of the mobile terminal device;
- and
- sending, from the mobile terminal device, the list to a network device during an attachment procedure,
- wherein the sending takes place during the attachment procedure of the mobile terminal device to a cellular network operator coordinated packet-switched only network.
A method, comprising:
- receiving, in an apparatus comprised in a packet-switched network, a list of circuit switched capabilities of a mobile terminal device during an attachment procedure;
- storing the list in a network device during the attachment procedure;
- and
- providing the list to a second network device during handover,
- wherein the receiving takes place during the attachment procedure of the mobile terminal device to a cellular network operator coordinated packet-switched only network.
An apparatus, comprising:
- a processor configured to prepare a list of circuit switched capabilities of a mobile terminal device;
- and
- a transmitter configured to send the list, from the mobile terminal device, to a network device during an attachment procedure,
- wherein the transmitter is configured to send the list during the attachment procedure of the mobile terminal device to a cellular network operator coordinated packet-switched only network.
An apparatus, comprising:
- a receiver configured to receive a list of circuit switched capabilities of a mobile terminal device during an attachment procedure;
- a memory configured to store the list in a network device;
- and
- a transmitter configured to provide the list to a second network device during handover,
- wherein the receiver is configured to receive the list during the attachment procedure of the mobile terminal device to a cellular network operator coordinated packet-switched only network.
A computer program embodied on a computer-readable medium, wherein the computer program is configured to cause a device to perform a method, the method comprising:
- preparing, in a mobile terminal device, a list of circuit switched capabilities of the mobile terminal device;
- and
- sending, from the mobile terminal device, the list to a network device during an attachment procedure,
- wherein the sending takes place during the attachment procedure of the mobile terminal device to a cellular network operator coordinated packet-switched only network.
