Description

FIELD OF THE INVENTION

This invention relates to wireless devices accessing and using external storage spaces provided by one or more servers that includes a method for a wireless device downloading a file from a remote server into an assigned external storage.

BACKGROUND INFORMATION

Storage system can be categorized as internal storage or external storage system.

The internal storages of a computing system include those storage media such as hard disk drives, memory sticks, memory, and others that are internally connected within the computing system through system bus or a few inches of cable. Therefore, the storage media actually are internal components of the computing system in a same enclosure.

The external storages of a computing system are those storage media that are not the internal components of the computing system in a same enclosure. Therefore, they have to be connected through longer cable, such as through Ethernet cable for IP based storage, Fiber channel cable for fiber channel storage, or wireless communication media, and others. The storage media of the external storage could be magnetic hard disk drives, solid state disk, optical storage drives, or memory card and could be in any form such as Raid which usually consists of a group of hard disk drives.

To effectively use a storage system, the storage devices of the storage system usually need to be partitioned into small volumes. After the partitioning, each of the volumes can be used for establishing a file system on top of it. To simplify the discussion, herein, the term of the storage volume and its corresponding file system, and the term of the storage partition are often used without differentiation in this invention.

CCDSVM in this invention is an abbreviation for a central controlled distributed scalable virtual machine. The CCDSVM allows a control management system to control a group of computing systems for providing distributed services to client systems over the Internet, Intranet, and LAN environment.

By the way, in this invention, the ISP refers to Internet service provider and the ASP refers to application service provider.

BRIEF DESCRIPTION OF THE INVENTION

Today, users commonly face a problem of lack of storage capacity in their wireless devices such as in their cell phones or personal data assistant devices (“PDA”), which are usually limited to 256 MB for the PDA and much less for the cell phone. To effectively solve this problem and let users possess multiple gigabytes (GB) of storage for their wireless devices as well as allowing the users to use the GB storage for their multimedia applications, the storage on a server can be used as the external storage for the wireless devices. This technology has been briefly introduced in the prior patent applications by the same author.

The followings describe details on how can the external storage actually be used by the wireless devices by referring to the FIG. 2. First, let each server unit 3 (e.g. the server 3 of the FIG. 2) partition its storage system in such way that each of volumes will have multiple GB in size. Therefore, a user of any one of the wireless devices can exclusively be assigned for access to a specific storage volume on the server unit 3. For example, if we need to provide each user a 4 GB storage space, then a 160 GB disk drive can support 40 users. Therefore, a 4096 GB storage system on the server unit 3 can support a total of 1024 users. Further, any data on the wireless device can be transmitted to the assigned storage volume on the server unit. In addition, the user on the wireless device also can download multimedia data from an ISP or ASP to the assigned storage volume of the designated server unit 3 through out-band approach as shown in FIG. 3. Finally, the user can use a web-browser, which has a functionality of invoking embedded video or music, to enjoy his/her stored multimedia contents.

These and other features, aspects and advantages of the present invention will become understood with reference to the following description, appended claims, and accompanying figures.

Partition Storage Volumes (Refer to the FIG. 2):

With this invention, the entire storage (10) on a server (3) needs to be partitioned into suitable size of volumes (11) such as 4 GB for each volume for allowing the server 3 to serve maximum number of the wireless devices (1). With the web console support software (5) of the server (3), the task of partitioning the storage system (10) can be done through a web-console (13) on a console host (12) by an administrative staff.

In order to support storage partition, first the console support software (5) of the server (3) must send storage information of the server (3), such as the information of the storage system (10), to the web-console (13) of the console host (12). The storage information includes each storage device name, storage size and others. Second, based on the storage information received, the administration staff on the console host (12) can use the web-console (13) to fill out partition information for the storage devices and send the storage partition information to the console support software (5) of the server (3). The storage partition information includes the number of the partitions (volumes) and the size of each partition (volume). Third, upon receiving the storage partition information from the web-console (13) of the console host (12), the console support software (5) of the server (3) performs the actual storage partition by dividing the entire storage into multiple small volumes. Finally, for each small storage volume, a corresponding file system could be built up.

Assign Storage Volumes (Refer to the FIG. 2):

Each of the storage volumes (11) together with its corresponding file system (11) on the storage system (10) of the server (3) needs to be exclusively assigned and exported to a given specific wireless device (1) by the console support software (5) of the server (3).

Data and Storage Volume Management (Refer to FIG. 2)

With the support of the console support software modules (5) of the server (3), a user on a web-browser (8) of the wireless device (1) can setup folder or directory structure on the file system of his/her assigned external storage volume (11). In addition, the user on the web-browser (8) of the wireless device (1) can performing all data management operations such as delete, copy, move, or rename and other operations for files or folders on that file system.

In order to support such data management over the external storage (10) by using the web browser (8) of the wireless device (1), first the console support software modules (5) of the server system (3) must communicate with the web-browser (8) of the wireless device (1) for presenting the external storage to a user on the wireless device. Therefore, the user from the web-browser (8) of the wireless device (1) can choose desired data management operation and submit the operation for the wireless device sending the operation information to the console support software modules (5) of the server system (3). These operations include establishing folder or directory, and copying, moving, or renaming data file and others for the folder or directory. Second, upon receiving each data management operations, the console support software modules (5) of the server system (3) actually performs the operations over the assigned file system of the assigned external storage volume (11) on the server system (3).

Store Data from Wireless Device into External Storage (Refer to FIG. 2):

To store the data such as digital photo pictures or messages into the assigned file system on the external storage (11) of a server (3), the other software modules (9) of the wireless device (1) need to send the data to the other service modules (7) of the server (3) via communication link between them. Upon receiving the data, the other service modules (7) of the server (3) write these data to the assigned file system of the assigned storage volume (11) on the server (3). The protocol used between these two communication entities could be either IP or non-IP based protocol.

Download Data from a Remote Web Server Site into External Storage (Refer to the FIG. 3):

If a user of a wireless device (1) wants to download data from a remote web server (15) into an assigned file system (11) of the assigned external storage on a server (3), the following steps are required:

1) Provide the user from a web-browser (8) of the wireless device (1) access to a remote web server site (15) to obtain information for the downloading via the path (a) of the FIG. 3. For example, to provide the use via the web browser obtains a web-page, which contains IP address of the remote web site and the data name for the downloading.

2) The other software modules (9) of the wireless device (1) obtains the downloading information, which becomes available in the cached web-pages on the wireless device (1) after the web-browser (8) accessing the web site (15).

3) The other software modules (9) of the wireless device (1) send the obtained downloading information to other service modules (7) of the storage server (3) via the path (b).

4) Upon receiving the downloading information from the wireless device (1), the other service module (7) of the storage server (3) sends a web download request to the web-site (15) via the path (c) based on download information obtained and then receives the downloading data from the web server of the web-site (15).

5) Upon receiving downloading data, the other service modules (7) of the storage server (3) write the data for the wireless device (1) into the assigned file system (11) on the server (3).

Retrieve Data from External Storage of a Wireless Device:

1) If a web-browser (8) has embedded video or music functionality, the web-browser (8) of a wireless device (1) can be used to retrieve and play multimedia data file such as video or music stored in the wireless device's external storage volume (11), which actually located on a server (3).

2) If there is needs, the other software module (9) of the wireless device (1) also can retrieve data file from the assigned file system of the assigned storage volume (11) on a server (3).

Support External Storage for Large Number of the Wireless Devices:

Referring now to the FIG. 4. If there is a need to provide each user a 2 GB of storage space, then a 160 GB disk drive can support 80 users. A 4096 GB (4 Tera Bytes) storage system on the server unit can support 2024 user. Therefore, a server unit 3 only can efficiently support a limited size of the storage system. In order to support a large number of the wireless devices, such as for supporting 500,000 wireless devices, a larger number of the servers is required, in this case 250 servers is required. In order to let a larger number of the servers to effectively support the larger number of the wireless devices, an infrastructure like the CCDSVM is desirable, which has been described in the prior patent applications. With the CCDSVM the control management system can control larger number of storage servers to provide external storage for a huge number of the wireless devices.
