Abstract
A node in a telephone network such as a switch stores associations between called and calling parties and colored ringback media played by the called party. Later, when the same calling party calls the called party, the node retrieves the stored ringback media and forwards the media to the calling party on behalf of the called party. In one embodiment, the node comprises a switch. In other embodiments, the node is a central server caching called/calling party combinations and associated ringback media and provides the ringback media forwarding function for a distributed population of called parties. Such called parties may comprise wireless phones.
Claims16
A method comprising:
- (a) during setup of a call from a calling party to a called party via a telephony network, the telephony network (i) receiving ringback media from the called party and forwarding the ringback media to the calling party and (ii) storing the received ringback media and an association between the ringback media and the calling and called parties;
- and
- (b) during setup of a subsequent call from the calling party to the called party, (i) a node in the telephony network determining, based at least in part on the stored association, that the ringback media should be played out to the calling party, and (ii) in response to the determining, retrieving the ringback media and playing out the ringback media to the calling party.
A method comprising:
- (a) during setup of a call from a calling party to a called party via a telephony network, the telephony network receiving ringback media from the called party and forwarding (i) to the calling party, the ringback media and (ii) to a ringback node, the ringback media, to enable the ringback node to store the ringback media and an association between the ringback media and the calling and called parties;
- (b) the ringback node receiving the ringback media, and the ringback node storing the ringback media and setting up the association;
- and
- (c) during setup of a subsequent call from the calling party to the called party, (i) a switching element in the telephony network determining, based at least in part on the stored association, that the ringback media should be played out to the calling party, and (ii) in response to the determining, the switching element causing the ringback node to retrieve the ringback media and to play out the ringback media to the calling party.
A system comprising:
- a switching element in a telephony network for (a) during setup of a call from a calling party to a called party, (i) receiving ringback media from the called party and forwarding the ringback media to the calling party and (ii) storing the received ringback media and an association between the ringback media and the calling and called parties, and (b) during setup of a subsequent call from the calling party to the called party, (i) determining based at least in part on the stored association, that the ringback media should be played out to the calling party, and (ii) in response to the determining, retrieving the ringback media and playing out the ringback media to the calling party.
