Abstract

Provided are apparatuses and methods for delivering service guide information to a mobile terminal via a presence server. In one example, a presence server receives information including service guide information corresponding to a program or service from a program source and store the received information under a presence identifier. The stored information may be delivered to a mobile terminal subscribing to a corresponding presence service. Alternatively, service guide information may be provided by another channel or backchannel.

24. The presence server of claim 23, wherein the network agent delivers the service guide information to the mobile terminal based on the presence identifier and the presence service.

25. The presence server of claim 24, wherein the presence network agent delivers update information corresponding to the service guide information based on the presence identifier.

26. The presence server of claim 19, wherein the presence network agent further collaborates with a second presence server.

27. The presence server of claim 26, wherein the collaborating includes exchanging service guide information with the second presence server and transmitting the exchanged service guide information to the mobile terminal.

28. The presence server of claim 27, wherein exchanging service guide information comprises receiving service guide information from the second presence server and combining the received service guide information from the second presence server with stored service guide information at the presence server to obtain the exchanged service guide information.

29. The presence server of claim 19, wherein the presence network agent receives the service guide information from a program source prior to transmitting the service guide information to the mobile terminal.

30. The presence server of claim 29, wherein the presence network agent further stores the service guide information under a corresponding presence identifier and transmits the service guide information to the mobile terminal based on the presence identifier.
