Abstract
A communication circuit arrangement may include a control circuit configured to receive an initial call notification attempt in idle mode from a first network for an incoming call that originates from a second network, establish an active connection with the first network, trigger a subsequent call notification attempt from the incoming call from the first network by disregarding the initial call notification attempt, and presenting a user with caller identity information for the incoming call provided in the subsequent call notification attempt.
Claims25
A communication circuit arrangement comprising:
- a control circuit configured to:
- receive an initial call notification attempt in idle mode from a first network for an incoming call that originates from a second network;
- establish an active connection with the first network;
- trigger a subsequent call notification attempt from the incoming call from the first network by disregarding the initial call notification attempt;
- and
- presenting a user with caller identity information for the incoming call provided in the subsequent call notification attempt.
A communication circuit arrangement comprising:
- a control circuit configured to:
- receive an idle mode paging message from a packet-switched network for an incoming call that originates from a circuit-switched network;
- establish an active connection with the packet-switched network;
- trigger transmission of a connected mode signaling message for the incoming call from the packet-switched network by disregarding the idle mode paging message;
- and
- respond to the connected mode signaling message to accept or reject the incoming call.
A non-transitory computer readable medium storing instructions that when executed by a controller of a radio communication device direct the radio communication device to perform a method comprising:
- receiving an initial call notification attempt in idle mode from a first network for an incoming call that originates from a second network;
- establishing an active connection with the first network;
- triggering a subsequent call notification attempt for the incoming call from the first network by disregarding the initial call notification attempt;
- and
- presenting a user with caller identity information for the incoming call provided in the subsequent call notification attempt.
A method of performing radio communications, the method comprising:
- receiving an initial call notification attempt in idle mode from a first network for an incoming call that originates from a second network;
- establishing an active connection with the first network;
- triggering a subsequent call notification attempt for the incoming call from the first network by disregarding the initial call notification attempt;
- and
- presenting a user with caller identity information for the incoming call provided in the subsequent call notification attempt.
