Abstract

A media portal is provided that is used to connect multimedia devices to other multimedia devices and content servers. When a call directed to a multimedia device busy in a call with the media portal is received, the media portal can provide a call waiting indication to the busy multimedia device without breaking the connection that is making the device busy. For example, if a first multimedia device is connected through the media portal to a content server providing streaming content of a football match, when a second device attempts to place a call to the first device, the media portal can provide a call waiting alert to the first device as part of, or as a substitute for, the delivery of the football match. Additionally the media portal can provide for the eventual connection of both devices while the previous call is still active.

Claims

1. A method of implementing call waiting in a multimedia communications network, comprising:

routing a first multimedia call between a first multimedia device and a second device through a network server, wherein the multimedia communications network directs the first multimedia device to a media portal that provides multimedia content for the first multimedia call and wherein the first multimedia device maintains a single connection during the first multimedia call and cannot open additional multimedia connections during the first multimedia call;

detecting that a third device is attempting to place a call to the first multimedia device, wherein the network server determines that the first multimedia device is engaged in the first multimedia call with the second device and wherein the multimedia communications network is configured to direct the third device to a mail server in response to the determination;

prior to the third device being directed to the mail server, rerouting the call from the third device to the network server in response to detecting that the first multimedia device is engaged in the first multimedia call;

using the network server to connect the call to the media portal that is providing the multimedia content for the first multimedia call in order to configure a call waiting capability of the first multimedia device;

generating a call-waiting alert at the media portal in response to detecting that the first multimedia device is engaged in the first multimedia call with the second device and in response to detecting that the third device is attempting to place the call to the first multimedia device, wherein the media portal incorporates the call-waiting alert within the multimedia content provided during the first multimedia call;

providing the call-waiting alert to the first multimedia device from the media portal over the single connection through the multimedia communications network;

using the media portal to determine whether the call has been accepted through the provided call-waiting alert; and

using the media portal to convert the call to a second multimedia call in response to determining that the first multimedia device has accepted the call through the provided call-waiting alert.

2. The method of claim 1, further comprising connecting the call from the third device to a mail system.

3. The method of claim 1, further comprising connecting the third device to the network server.

8. The method of claim 1, further comprising accepting a response from the first multimedia device, following receipt of the call-waiting alert, indicative of whether a user desires to accept the call from the third device.

9. The method of claim 8, further comprising connecting the call from the third device to the first multimedia device through the network server, if the response indicates that the user desires to accept the call from the third device.

10. The method of claim 8, further comprising connecting the call from the third device to a mail system, if the response indicates that the user does not desire to accept the call from the third device.

4. A system for implementing call waiting in a multimedia communications network, the system comprising:

a server connected to the multimedia communications network and configured to control connection of calls between at least a first multimedia device, which sends and receives multimedia calls and multimedia content, and a second device, wherein the server is configured to;

route a first multimedia call between a first multimedia device and a second device through a network server, wherein the multimedia communications network directs the first multimedia device to a media portal that provides the multimedia content for the first multimedia call and wherein the first multimedia device maintains a single connection during the first multimedia call and cannot open additional multimedia connections during the first multimedia call;

detect that a third device is attempting to place a call to the first multimedia device, wherein the network server determines that the first multimedia device is engaged in the first multimedia call with the second device and wherein the multimedia communications network is configured to direct the third device to a mail server in response to the determination;

prior to the third device being directed to the mail server, reroute the call from the third device to the network server in response to detecting that the first multimedia device is engaged in the first multimedia call;

use the network server to connect the call, to the media portal that is providing the multimedia content for the first multimedia call in order to configure a call waiting capability of the first multimedia device;

generate a call-waiting alert at the media portal in response to detecting that the first multimedia device is engaged in the multimedia call with the second device and in response to detecting that the third device is attempting to place a call to the first multimedia device, wherein the media portal incorporates the call-waiting alert within the multimedia content provided during the multimedia call;

provide the call-waiting alert to the first multimedia device from the media portal over the single connection through the multimedia communications network;

use the media portal to determine whether the call has been accepted through the provided call-waiting alert; and

use the media portal to convert the call to a second multimedia call in response to determining that the first multimedia device has accepted the call through the provided call-waiting alert.

5. The system of claim 4, wherein the third device connects to the first multimedia device through the media portal.

6. The system of claim 4, further comprising a mail system to which the call from the third device is connected by the media portal.

7. The system of claim 4, wherein the third device is connected to the network server.

11. The system of claim 4, wherein the server is further configured to connect the call from the third device to the first multimedia device through the network server in response to receiving a response from the first multimedia device.
