Send a status update message to a second network associated with the second SIM, wherein the status update message instructs the second network to provide a busy status message in response to receiving a call connection request that is directed to the second SIM, wherein, after sending the status update message, the apparatus does not receive a paging message from the second network in response to the second network receiving the call connection request that is directed to the second SIM.
Process a call connection between the apparatus and a first network associated with the first SIM and a first subscriber identity module (SIM) interface to receive a first SIM Ī second SIM interface to receive a second SIM and.The method of claim 1, wherein the status update message includes one of an unstructured supplementary service data (USSD) message and a short messaging service (SMS) message. The method of claim 1, wherein the status update message is communicated using one of a supplementary service and a short messaging service. The method of claim 5, further comprising sending a second status update message to the second network associated with the second SIM in response to termination of the incoming call, wherein the second status update message informs the second network of the termination of the incoming call, wherein, after sending the second status update message, the UE device receives a paging message from the second network in response to the second network receiving a call connection request that is directed to the second SIM. The method of claim 1, wherein the call connection is processed in response to receipt of a notification of an incoming call from the first network associated with the first SIM, and wherein the status update message is sent to the second network associated with the second SIM prior to receipt of the incoming call.
The method of claim 3, further comprising sending a second status update message to the second network associated with the second SIM in response to termination of the outgoing call, wherein the second status update message informs the second network of the termination of the outgoing call, wherein, after sending the second status update message, the UE device receives a paging message from the second network in response to the second network receiving a call connection request that is directed to the second SIM. The method of claim 1, wherein the call connection is processed in response to receipt of a request to initiate an outgoing call from the UE device to the first network associated with the first SIM, and wherein the status update message is sent to the second network associated with the second SIM prior to initiation of the outgoing call. The method of claim 1, wherein the busy status message is different from an unreachable status message provided by the second network when the UE device is not reachable. Sending a status update message to a second network associated with a second SIM of the UE device, wherein the status update message instructs the second network to provide a busy status message in response to receiving a call connection request that is directed to the second SIM, wherein, after sending the status update message, the UE device does not receive a paging message from the second network in response to the second network receiving the call connection request that is directed to the second SIM.
processing a call connection between a user equipment (UE) device and a first network associated with a first subscriber identity module (SIM) and.
