Abstract

A system and method for managing messaging in a mobile communication system (e.g., having power-save capability) in a multiple network environment. For example, the mobile communication system may operate in a power-save mode (e.g., a mode in which the mobile communication system does not communicate messages). The mobile communication system may exit the power-save mode. After exiting from the power-save mode, the mobile communication system may determine to establish communication with a second system (e.g., a message server) over a second communication path instead of a first communication path. Communication with the second system may be established over the second communication path, and message-related information may be communicated between the mobile communication system and the second system. Such message-related information may, for example, comprise message information, information regarding message availability, or information regarding the communication of message information.

Claims

1. In a mobile communication device that is capable of communicating with a second system over a first communication path comprising a first set of one or more independent communication networks and communicating with the second system over a second communication path comprising a second set of one or more independent communication networks, at least a portion of the second set different from the first set, a method for retrieving one or more messages from the second system, the method comprising:

in the mobile communication device;

exiting from a power-save mode of operation, in which the mobile communication device does not receive messages from the second system; and

after said exiting from the power-save mode of operation;

determining to establish communication with the second system over the second communication path instead of over the first communication path to retrieve messages from the second system;

establishing communication with the second system over the second communication path; and

retrieving one or more messages from the second system over the second communication path.

2. The method of claim 1, wherein determining to establish communication with the second system over the second communication path comprises determining the availability of the second communication path.

3. The method of claim 2, wherein determining the availability of the second communication path comprises one or both of:

receiving a beacon signal transmitted from an access point of the second communication path; and

transmitting a beacon signal that is received by an access point of the second communication path.

4. The method of claim 1, wherein the second communication path is communicatively coupled to the second system through at least a portion of the first communication path.

5. The method of claim 1, wherein the first communication path comprises a telecommunication network, and the second communication path comprises a computer network.

6. The method of claim 1, wherein the second communication path comprises one or both of:

a local area network and a personal area network.

7. The method of claim 1, wherein determining to establish communication with the second system over the second communication path instead of over the first communication path comprises determining that communicating with the second system over the second communication path will be more energy-efficient than communicating with the second system over the first communication path.

8. The method of claim 1, wherein determining to establish communication with the second system over the second communication path instead of over the first communication path comprises determining that communicating with the second system over the second communication path is higher priority than communicating with the second system over the first communication path.

9. The method of claim 1, wherein determining to establish communication with the second system over the second communication path instead of over the first communication path comprises:

attempting to communicate with the second system over the first communication path to check for pending messages; and

if attempting to communicate with the second system over the first communication path to check for pending messages fails, then determining to establish communication with the second system over the second communication path.

10. The method of claim 9, wherein:

attempting to communicate with the second system over the first communication path to check for pending messages comprises attempting to communicate with a message server over the first communication path to check for pending messages; and

establishing communication with the second system over the second communication path comprises establishing communication with the message server over the second communication path.

11. The method of claim 9, wherein attempting to communicate with the second system over the first communication path to check for pending messages comprises determining the availability of the first communication path by at least one of:

receiving a beacon signal transmitted from an access point of the first communication path; and

transmitting a beacon signal that is to be received by an access point of the first communication path.

12. The method of claim 9, comprising determining to attempt to communicate with the second system over the first communication path to check for pending messages prior to attempting to communicate with the second system over the second communication path to check for pending messages.

13. The method of claim 12, wherein determining to attempt to communicate with the second system over the first communication path to check for pending messages prior to attempting to communicate with the second system over the second communication path to check for pending messages comprises determining that communicating over the first communication path consumes less electrical energy than communicating over the second communication path.

14. The method of claim 12, wherein determining to attempt to communicate with the second system over the first communication path to check for pending messages prior to attempting to communicate with the second system over the second communication path to check for pending messages comprises determining that communicating over the first communication path is higher priority than communicating over the second communication path.

15. The method of claim 9, wherein the second communication path comprises at least a portion of the first communication path.

16. The method of claim 9, wherein the first communication path comprises a telecommunication network, and the second communication path comprises a computer network.

17. The method of claim 9, wherein the second communication path comprises at least one of:

a personal area network and a local area network.

18. A mobile communication device comprising:

a communication interface module that is capable of communicating with a second system over a first communication path comprising a first set of one or more independent communication networks and communicating with the second system over a second communication path comprising a second set of one or more independent communication networks, at least a portion of the second set different from the first set; and

at least one module that operates to, at least;

operate the mobile communication device in a power-save mode; and

after the mobile communication device exits the power-save mode;

determine to establish communication with the second system over the second communication path instead of over the first communication path to retrieve messages from the second system;
