Notification of waiting voicemail messages between different types of communication networks

摘要

Systems and methods are disclosed that provide notification of waiting voicemail messages between different types of communication networks. A first communication network as described herein includes a voicemail server to store voicemail messages for a user of a communication device. A second communication network provides phone service to the communication device but uses a different signaling protocol than the first communication network. In order to notify the user of the waiting voicemail message in the voicemail server, a subscriber server (e.g., an HLR) in the first communication network receives a voicemail waiting indicator in the signaling protocol of the first communication network, identifies the signaling protocol of the second communication network, and converts the voicemail waiting indicator to the signaling protocol of the second communication network. The second communication network may then provide notification of the waiting voicemail message to the user.

主权项

1. A subscriber server adapted to notify a user of a communication device of a waiting voicemail message, where the communication device is dual mode and is able to receive service from a first communication network and a second communication network, the subscriber server comprising:
a processor; a first interface adapted to receive a voicemail waiting indicator in a first signaling protocol indicating that a voicemail message for the user is being stored by a voicemail server in the first communication network for a call placed to the communication device, wherein the communication device is receiving phone service from the second communication network that uses a second signaling protocol that is different than the first signaling protocol used in the first communication network; a processing system adapted to identify the second signaling protocol used in the second communication network that is providing phone service to the communication device of the user, and to convert the voicemail waiting indicator in the first signaling protocol to the second signaling protocol; and a second interface adapted to transmit the voicemail waiting indicator in the second signaling protocol to the second communication network to provide for notification of the waiting voicemail message to the user of the communication device; wherein the first interface, the processing system and the second interface are executed by the processor.
