Abstract:
1. In a radio access network (RAN) that defines at least one wireless coverage area in which the RAN serves at least one wireless communication device (WCD), a method for managing message waiting notification, the method comprising: the RAN determining that the WCD has missed an incoming call; in response to determining that the WCD has missed the incoming call, (i) the RAN routing the call to a message storage system to enable an originator of the call to leave a message for a user of the WCD, (ii) in response to (a) the RAN waiting a period of time after routing the call to the message storage system, and (b) the RAN determining that, since routing the call to the message storage system, no message waiting indication (MWI) has been transmitted to the WCD and the WCD has not prompted the RAN to query the message storage system, the RAN generating and transmitting a message waiting query to the message storage system to trigger the message storage system to transmit a signal indicative of the MWI to the WCD; the RAN receiving from the message storage system, in response to the message waiting query, the signal; and in response to receiving the signal, the RAN transmitting to the WCD an MWI indicative of the message, for presentation of the MWI to the user of the WCD.
