Abstract

A system and method are described for providing dynamic mobile cache for mobile computing devices. In one embodiment, a cache is created at a server at the time a communication session between the server and a client is initiated. The server then determined whether the client requires the cache. If it is determined the client requires the cache, the server provides the cache to the client.

Claims

1. A method comprising:

initiating a first session between a server and a client;

creating a cache at the server in response to the first session being initiated between the server and the client;

maintaining the cache at the server until one or more factors to move the cache to the client are satisfied;

determining whether the one or more factors are satisfied;

moving the cache to the client if the one or more factors are satisfied;

recapturing the cache at the server prior to ending of the first session;

updating the cache at the server while the client is disconnected from the server;

initiating a second session between the server and the client;

re-determining whether the one or more factors are satisfied upon reconnection of the client to the server for the second session; and

moving the updated cache to the client if the one or more factors are satisfied, the updated cache including the cache from the first session.

2. The method of claim 1, wherein the one or more factors comprises one or more of the client requesting the cache, pattern of communication between the client and the server, frequency at which the client and the server communicate, available resources of the client, system capabilities of the client, past performance of the client, current performance of the client, and nature of current tasks being performed by the client.

3. The method of claim 1, wherein the maintaining of the cache at the server comprises observing the communication between the client and the server to update the cache at the server according to observing of the communication, prior to moving the cache to the client.

4. The method of claim 3, wherein the communication between the client and the server comprises one or more of receiving requests at the server from the client, and sending replies from the server to the client in response to the requests received.

5. A system comprising:

a client to initiate a first session with a server; and

the server coupled to the client, the server to

create a cache in response to the session being initiated between the server and the client,

maintain the cache at the server until one or more factors to move the cache to the client are satisfied,

determine whether the one or more factors are satisfied,

move the cache to the client if the one or more factors are satisfied,

recapture the cache at the server prior to ending of the first session,

update the cache at the server while the client is disconnected from the server,

initiate a second session between the server and the client,

re-determine whether the one or more factors are satisfied upon

reconnection of the client to the server for the second session, and move the updated cache to the client if the one or more factors are satisfied, the updated cache including the cache from the first session.

6. The system of claim 5, wherein the one or more factors comprise one or more of the client requesting the cache, pattern of communication between the client and the server, frequency at which the client and the server communicate, available resources of the client, system capabilities of the client, past performance of the client, current performance of the client, and nature of the current tasks being performed by the client.

7. The system of claim 5, wherein the client comprises a mobile computing system including one or more of a laptop computer, a pocket computer, a personal digital assistant (PDA), and a telephone.

8. The system of claim 5, wherein the server is further to observe the communication between the client and the server to update the cache at the server according to the observing of the communication, prior to moving the cache to the client.

9. A machine-readable storage medium having instructions which, when executed, cause a machine to:

initiate a session between a server and a client;

create a cache at the server in response to the session being initiated between the server and the client;

maintain the cache at the server until one or more factors to move the cache to the client are satisfied;

determine whether the one or more factors are satisfied;

move the cache to the client if the one or more factors are satisfied;

recapture the cache at the server prior to ending of the first session;

update the cache at the server while the client is disconnected from the server;

initiate a second session between the server and the client;

re-determine whether the one or more factors are satisfied upon reconnection of the client to the server for the second session; and

move the updated cache to the client if the one or more factors are satisfied, the updated cache including the cache from the first session.

10. The machine-readable storage medium of claim 9, wherein the one or more factors comprise one or more of the client requesting the cache, pattern of communication between the client and the server, frequency at which the client and the server communicate, available resources of the client, system capabilities of the client, past performance of the client, current performance of the client, and nature of the current tasks being performed by the client.

11. The machine-readable storage medium of claim 9, wherein the instructions when executed to maintain the cache at the server, further cause the machine to observe the communication between the client and the server to update the cache at the server according to the observing of the communication, prior to moving the cache to the client.

12. The machine-readable storage medium of claim 11, wherein the communication between the client and the server comprises one or more of receiving requests from the client at the server, and sending replies from the server to the client in response to the requests received.
