Abstract
A method and apparatus for determining handover (HO) signaling in a communications network. The method of the present invention examines the International Mobile Subscriber Identity (IMSI) of a user equipment (UE) during HO and, based on the examination, determines whether Single Radio Voice Call Continuity (SRVCC) or circuit switched (CS) over Long Term Evolution (LTE) using a Generic Access Network Controller (GANC) should be used in the HO.
Claims25
A method for determining handover (HO) signaling in a communications network, comprising the steps of:
- examining the International Mobile Subscriber Identity (IMSI) of a user equipment (UE) during HO;
- and
- based on the examination, determining whether Single Radio Voice Call Continuity (SRVCC) or circuit switched (CS) over Long Term Evolution (LTE) using a Generic Access Network Controller (GANC) shall be used in the HO.
An apparatus for determining handover (HO) signaling in a communications network, comprising:
- a handover selection function (HOSF) circuit having an examining means for examining the International Mobile Subscriber Identity (IMSI) of a user equipment (UE) during HO and a determination means for determining, based on the examination, whether Single Radio Voice Call Continuity (SRVCC) or circuit switched (CS) over Long Term Evolution (LTE) using a Generic Access Controller Network (GANC) shall be used in the HO.
