Abstract:
Briefly, in accordance with one embodiment of the invention, a music player may receive a requested music file through a wireless communication. For example, the device may establish a peer-to-peer wireless communication path(s) with another device to initiate a request for a music file without a priori knowledge of whether the file is available to the another device. The device may then receive the music file from the remote device through a peer-to-peer wireless communication path(s).

Description:
BACKGROUND 
   In order to provide consumers with greater flexibility in the music that they listen to, for example, while in an automobile, devices have been developed that allow a user to store music files into memory that may be played back as the user desires. The typical device may include hard disk drives that may be removed to be programmed. The hard disk may be connected to a personal computer (PC) or a music system so that the music may be transferred from a compact disc to the hard disk drives. The hard disk drives may also be programmed with music files (e.g., MP3 files) that are downloaded from the internet. 
   However, there are several drawbacks to music players that rely on hard disk drives to store music. To begin, the hard disk drives are expensive and may not be well suited for all applications. For example, if the music player is used in an automobile environmental conditions such as temperature and vibrations may affect the reliability and performance of the disk drives. Also, the disk drives must be removed from the player (e.g., from the automobile) and hard wired to a personal computer if the music files are to be updated. 
   Another alternative music system, allow a user to subscribe to a music service that may provide music to a user through a satellite network. However, such systems do not allow the user to select the music to be played as the service, not the user, determines what music is to be played. Thus, there is a continuing need to provide music to a user.

   Turning to  FIG. 1 , an embodiment  100  in accordance with the present invention is described. Embodiment  100  may comprise a music player  50  that may be portable (e.g. part of a cell phone, a two-way radio communication system, a one-way pager, a two-way pager, a personal communication system (PCS), a portable computer, or the like) or may be mounted in a mobile device such as an automobile. Although it should be understood that the scope and application of the present invention is in no way limited to these examples as the scope of the present invention is intended to include device that are not considered portable as well. 
   Music player  50  may comprise a transceiver  51  that may be used to request and/or receive music files requested by a user. Although the scope of the present invention is not limited in this respect, transceiver  51  may include a transmitter and a receiver that may be used to wirelessly communicate with a network. Alternatively, music player may only have a wireless transmitter or a wireless receiver. 
   Music player  50  may use a variety of communication techniques to request or receive music files. Although the scope of the present invention is not limited in this respect, types of cellular radiotelephone communication systems intended to be within the scope of the present invention include, although not limited to, Code Division Multiple Access (CDMA) cellular radiotelephone communication systems, Global System for Mobile Communications (GSM) cellular radiotelephone systems, North American Digital Cellular (NADC) cellular radiotelephone systems, Time Division Multiple Access (TDMA) systems, Extended-TDMA (E-TDMA) cellular radiotelephone systems, Bluetooth™ , third generation (3G) systems like Wide-band CDMA (WCDMA), CDMA-2000, and the like. 
   If a user would like to hear some music that is not already stored within music player  50  (e.g., within memory  52 ), transceiver  51  may use a wireless communication protocol to request a music file stored on either a personal computer  60 , the internet  71 , or another server  80 . However, it should be understood that the scope of the present invention is not limited to the source of the requested music file. In alternative embodiments, the music file may come from a stereo system or from another music player that is part of a peer-to-peer system. 
   As shown in  FIG. 1 , personal computer  60  may comprise a transceiver  67  that may be used to provide the requested music file to music player  50 . Although the scope of the present invention is not limited in this respect, personal computer  60  may be a general processing computer used to execute user applications. Accordingly, personal computer  60  may have the requested music file on its storage device (e.g. a hard drive, compact disk, etc.). However, personal computer  60  may also be a terminal or portal device that is connected to a network or the internet  71 . In such an embodiment, personal computer  60  may access and retrieve the music file requested by music player  50 . 
   In yet another embodiment, a user may store selected music files on a database within the internet  71  or within a database on a server  80 . This may be advantageous if music player  50  may have greater or faster accessibility to server  80  rather than personal computer  60 . Storing music files on server  80  may also be desirable if the music files are to be shared with other users or is the user is requesting the music file from a service that sells the music, although the scope of the present invention is not limited in this respect. 
   A method in accordance with an embodiment of the present invention is now provided. A user of music player  50  may request a music file that is not currently stored within memory  52 . In this particular example, the user may make the request from an automobile. This request may be made directly to personal computer  60  or server  80 , or to a service provider through a base station  85 . Personal computer  60  may then provide the requested music file through a wireless communication, such as WCDMA (indicated in  FIG. 1  with an arrow  61 ). Music player  50  may receive the requested music file through the wireless communication and store the music file in memory  52 . Although the scope of the present invention is not limited in this respect, memory  52  may comprise volatile memory, such as static random access memory (SRAM), dynamic RAM (DRAM), etc., or non-volatile memory such as flash, EEPROM, etc. Once stored in memory  52 , the user may play the music file at his leisure. 
   Referring now to  FIG. 2 , an alternative embodiment of the present invention. Instead of requesting music files from a computer, a server, or the internet, music player  50  may receive a requested music file from other music players in a peer-to-peer network. For example, music players  50 , and  251 – 252  may be in different automobiles that are in communication with other in a peer-to-peer network. Accordingly, music player  50  may transmit a request for a music file to music player  251  (indicated in  FIG. 2  with an arrow  90 ). If music player  251  does not have the requested song or file, it may transmit a request to music player  252  (arrow  91 ). If music player  252  has the requested song, it may then transmitted the requested music file to music player  50  (arrow  92 ). It should be understood that the scope of the present invention is not limited by the number of music players that are in the peer-to-peer network, and not all of them need me mobile (e.g., within an automobile). In addition, the peer-to-peer network may also comprise all or some of the components shown in  FIG. 1 . For example, the peer-to-peer network may also include person computers, servers, base stations, or portals to the internet. 
   While certain features of the invention have been illustrated and described herein, many modifications, substitutions, changes, and equivalents will now occur to those skilled in the art. For example, a user may request and receive more than one music file (e.g., all the songs on an album). It is, therefore, to be understood that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the invention.
