Abstract:
A method for operating a packet switched wireless network to service communications for a mobile terminal that services both packet switched communications and circuit switched communications, the method comprising:receiving an attach request message from the mobile terminal by a servicing support node of the packet switched wireless network; authenticating the mobile terminal; the servicing support node of the packet switched wireless network interacting with a home subscriber service function of the packet switched wireless network to receive the mobile terminal's subscriber data; the servicing support node of the packet switched wireless network interacting with a home subscriber service function of the packet switched wireless network to update the mobile terminal's location; the servicing support node of the packet switched wireless network responding to the mobile terminal with an attach accept message; wherein the attach accept message indicates that the mobile terminal will be provided with packet switched service when the mobile terminal's subscriber data indicates that the mobile terminal subscribes to packet switched service; wherein the attach accept message indicates that the mobile terminal will be provided with circuit switched service when the mobile terminal's subscriber data indicates that the mobile terminal is not subscribed to packet switched service; and servicing communications for the mobile terminal consistently with the attach accept message.
