Methods and systems for providing application level presence information in wireless communication

摘要

Methods and apparatus for determining and maintaining user presence information include capturing user presence data with an application presence server. The application presence server can be configured to update user presence data as a user initiates or exits an application. Applications associated with user presence data are configured to query an application proxy client concerning user presence data of a selected user and, based on a returned user status, deliver, discard, or redirect a message intended for the user. User presence data is stored in a user presence repository and can be provided via Internet-based or other connections to applications executed on external networks. User activity status can be used to select or update user presence data. In some examples, an application server of an external network is configured to receive user presence data from the presence server.

主权项

1. A method comprising:
receiving, at a first application server from a mobile station, an initiation of an instant messaging application; in response to receiving the initiation of the instant messaging application, providing, by the first application server to a first presence server, a communication that a first user associated with the mobile station is active, wherein the first presence server sets presence data for the first user to active based on the communication; providing, to a second user who is a member of a list associated with the first user, the presence data for the first user; determining that the mobile station has not accessed the instant messaging application for a predetermined amount of time; in response to determining that the mobile station has not accessed the instant messaging application for the predetermined amount of time, sending, to the mobile station, an alert; upon determining that no response to the alert is received from the mobile station, updating the presence data for the first user from active to present and inactive; in response to determining that the mobile station has entered a sleep mode, updating the presence data for the first user; receiving, at the first application server from the second user, a message for delivery to the mobile station of the first user; and delivering the message to the mobile station of the first user based on the presence data for the first user.
