Abstract

The present disclosure relates to a mobile switching node and a mobility management node to page a terminal device. The present disclosure may provide a method for a mobile switching node to page a terminal device. The method includes: storing (S201) an indication of whether a terminal device supports a circuit switching call function; receiving (S202) a request to implement the circuit switching call function, in regard to a subscriber number corresponding to the terminal device; and sending (S203), to a mobility management node, a circuit switching paging request for the terminal device, in response to that the indication shows the terminal device supports the circuit switching call function.

First claim

1 - 43 . (canceled)

44 . A method for a mobile switching node to page a terminal device, the method comprising:
storing an indication of whether a terminal device supports a circuit switching call function; receiving a request to implement the circuit switching call function in regard to a subscriber number corresponding to the terminal device; and sending, to a mobility management node, a circuit switching paging request for the terminal device, in response to the indication indicating that the terminal device supports the circuit switching call function.

45 . The method of claim 44 :
wherein the subscriber number corresponds to a plurality of terminal devices; and wherein the terminal device to receive the circuit switching paging is selected from the plurality of terminal devices, based on the indication.

46 . The method of claim 44 , wherein the indication is received from the mobility management node.

47 . The method of claim 46 , wherein the indication is received from the mobility management node using a location update request.

48 . The method of claim 44 , wherein the indication shows that the terminal device supports only short message service, or both short message service and circuit switched fallback voice call service.

49 . A method for a mobility management node to page a terminal device, the comprising:
determining whether a terminal device supports a circuit switching call function; and sending, to a mobile switching node, an indication of whether the terminal device supports a circuit switching call function.

50 . The method of claim 49 , further comprising:
receiving, from a mobility management node, a circuit switching paging request for the terminal device; and paging the terminal device.

51 . The method of claim 49 , wherein the determining whether the terminal device supports the circuit switching call function is based on an information element in a combined attach request or in a tracking area update request from the terminal device.

52 . The method of claim 49 , wherein the indication is sent to the mobile switching node using a location update request.

53 . A mobile switching node device to page a terminal device, the mobile switching node comprising:
processing circuitry; memory containing instructions executable by the processing circuitry whereby the mobile switching node device is operative to:
store an indication of whether a terminal device supports a circuit switching call function;
receive a request to implement the circuit switching call function in regard to a subscriber number corresponding to the terminal device; and
send, to a mobility management node, a circuit switching paging request for the terminal device, in response to the indication indicating that the terminal device supports the circuit switching call function.

54 . The mobile switching node device of claim 53 :
wherein the subscriber number corresponds to a plurality of terminal devices; and wherein the terminal device to receive the circuit switching paging is selected from the plurality of terminal devices based on the indication.

55 . The mobile switching node device of claim 53 , wherein the instructions are such that the mobile switching node device is operative to receive the indication from the mobility management node.

56 . The mobile switching node device of claim 53 , wherein the indication shows that the terminal device supports only short message service, or both short message service and circuit switched fallback voice call service.

57 . A mobility management node device to page a terminal device, the mobility management node comprising:
processing circuitry; memory containing instructions executable by the processing circuitry whereby the mobility management node device is operative to:
determine whether a terminal device supports a circuit switching call function; and
send, to a mobile switching node, an indication of whether the terminal device supports a circuit switching call function.

58 . The mobility management node device of claim 57 , wherein the instructions are such that the mobility management node device is operative to:
receive, from a mobility management node, a circuit switching paging request for the terminal device; and page the terminal device.

59 . The mobility management node device of claim 57 , wherein the instructions are such that the mobility management node device is operative to determine whether the terminal device supports the circuit switching call function based on an information element in a combined attach request or in a tracking area update request from the terminal device.

60 . The mobility management node device of claim 57 , wherein the instructions are such that the mobility management node device is operative to receive the indication in a location update request.

61 . The mobility management node device of claim 57 , wherein the indication shows that the terminal device supports only short message service, or both short message service and circuit switched fallback voice call service.
