Definitions

  • the present invention relates to wireless communication devices and their accessories. More particularly, the present invention relates to a novel and improved method and system for interfacing a wireless communication device with an accessory.
  • a wireless communication device such as a portable telephone will typically interface with one or more accessories, including car kit adapters, battery chargers, docking stations or data cradles, holsters, and the like.
  • accessories may expand the functionality or usability of the portable telephone.
  • the portable telephone when the portable telephone is interfaced to a traditional car kit adapter, it will generally receive power from the automobile's battery or alternator.
  • the car kit adapter may include circuits which allow hands-free operation, voice recognition, and other useful functions.
  • the portable telephone To the extent that the portable telephone is able to interface with these external accessories, it traditionally has been programmed with control software to direct the operation of the external accessory. This has required that the portable telephone contain control software for each of the possible external accessories with which it may possibly interface, even though the actual user of the particular portable telephone in question may not own any external accessories. This leads to increased cost and size of the portable telephone because it must contain enough memory to carry all the possible accessory control software.
  • the present invention is a novel and improved method and system for interfacing a wireless communication device with an external accessory.
  • the system includes an attach detector for detecting an attachment of the wireless communication device and the external accessory.
  • a controller downloads accessory interface software from the external accessory to the wireless communication device.
  • the wireless communication device interfaces with the external accessory according to instructions in said accessory interface software.
  • the controller initiates authentication of said external accessory prior to downloading the accessory interface software and refuses to interface with the external accessory if the authentication fails.
  • the size and cost of memory in the mobile station will be substantially less than the total memory required to store all of the accessory interface software for all possible accessories, as is traditionally required in the prior art.
  • the non-volatile memory size requirements for the mobile station are reduced due to the accessory specific interface software being stored in the external accessory itself for dynamic upload to the mobile station only when it is required.
  • FIG. 1 is a functional block diagram of the system of the present invention.
  • FIG. 2 is a flow diagram of the method of the present invention. 3
  • the present invention is applicable to any wireless communication device, including cellular telephones, PCS telephones, Wireless Local Loop (WLL) telephones, and other wireless communication devices as are known in the art.
  • the wireless communication device will be referred to herein as a mobile station, but it is understood that the present invention is equally applicable to fixed, or non-portable telephones.
  • FIG. 1 a functional block diagram of the present invention is illustrated.
  • a mobile station 100 such as a cellular or PCS telephone is illustrated as interfacing with an external accessory 102, such as a hands-free car adapter or a data dock.
  • Mobile station 100 interfaces with external accessory 112 through an interface 112.
  • Interface 112 may be an electrical connector and associated circuitry as is known in the art for the transfer of data signals.
  • the interface 112 may be a Universal Serial Bus (USB) interface as is known in the art.
  • interface 112 may be similar to that described in detail in copending U. S. Patent Application Serial No. 08/593,305, entitled “PORTABLE COMMUNICATION DEVICE AND ACCESSORY SYSTEM", filed January 31, 1996, assigned to the assignee of the present invention and incorporated herein by reference.
  • the just-mentioned patent describes a portable communications device and accessory system which enables both voice and control commands to be communicated between a mobile station and external accessories over a single flexible digital interface.
  • a mobile station controller configures the serial communications bus to pass both the digital voice data and digital control commands to and from the external power booster and the hands-free kit.
  • the external hands-free kit contains its own auxiliary CODEC for encoding analog voice signals and decoding the digital voice data.
  • the mobile station controller configures the serial communication bus to pass the digital voice data to and from an internal CODEC for use with the portable device's own microphone and speaker.
  • interface 112 may be a wireless interface using radio frequency (RF), infra-red (IR), or magnetic B-field modulation as is known in the art.
  • RF radio frequency
  • IR infra-red
  • magnetic B-field modulation as is known in the art.
  • the specific configuration of interface 112 is not critical to the present invention, and any suitable interface 4 circuitry or method may be used. However, in the preferred embodiment, interface 112 conforms to the USB Specification.
  • mobile station 100 includes an attach detector 110 which functions to detect the attachment of the external accessory 102 through interface 112.
  • attach detector 110 depends on the technology used for interface 112, whether it be USB, proprietary electrical connection circuitry, IR, RF, or B-field.
  • attach detector 110 detects the physical connection of mobile station 100 to external accessory 102 by detecting a transition in current from an idle level to an active level in interface 112 when mobile station 100 is connected to external accessory 102.
  • attach detector 110 may actively "poll" interface 112 for an attached condition. For example, in an embodiment where interface 112 is an IR interface, attach detector 110 periodically polls interface 112 for a presence message.
  • attach detector 110 periodically reads a receiver ADC of interface 112 to detect a value.
  • attach detector 110 may be any detection circuitry as is known in the art, whether it detects a transition passively, or actively polls interface 112.
  • attach detector 110 does not strictly refer to physical or mechanical attachment.
  • the term “attach” is defined more broadly as sufficient proximity between the mobile station 100 and the external accessory 102 as to allow the communications described herein below. For example, if interface 112 is a standard USB electrical interface, physical touching of the data connectors of external accessory 102 and mobile station 100 is the requisite attachment.
  • interface 112 is a wireless interface such as IR, RF, or B-field
  • attachment occurs when the mobile station 100 and the external accessory 102 are within sufficient proximity to allow communication between the two.
  • the actual physical proximity required for attachment is dependent on the nature of the technology used, including the strength of any wireless transmitters, and the sensitivity of any wireless receivers that comprise interface 112.
  • attach detector 110 Upon detecting the attachment of the external accessory 102 through interface 112, attach detector 110 generates an attach signal, preferably in the form of an interrupt, to mobile station controller 110. In response to the attach signal, mobile station controller 108 begins executing instructions contained in mobile station control memory 104.
  • mobile station control memory 104 contains software code for executing the method described herein, and with further reference to FIG. 2 below.
  • Mobile station 5 control memory 104 may be any memory device or type as is known in the art. In the preferred embodiment, mobile station control memory 104 is non-volatile flash memory.
  • Mobile station controller 108 in response to the software instructions contained in mobile station control memory 104, acts as a "host" entity in relation to external accessory 102. To this end, mobile station controller 108 polls accessory controller 114 to verify the presence of external accessory 102. Accessory controller 114 may be any suitable microcontroller or programmable microprocessor as is known in the art. In response to the poll from mobile station controller 108, accessory controller 114 begins executing instructions contained in accessory control memory 116. Specifically, accessory control memory 104 contains software code for executing the method described herein, and with further reference to FIG. 2 below. Accessory control memory 116 may be any memory device or type as is known in the art. In the preferred embodiment, accessory control memory 104 is non-volatile flash memory.
  • Accessory controller 114 in response to the software instructions contained in accessory control memory 116, acts as a "client” entity in relation to mobile station controller 108, which as previously stated, acts as a "host” entity.
  • the "host” and “client” roles are reversed, with the external accessory 102 acting as the "host”, and the mobile station 100 acting as the "client.”
  • the attach detector 110 would be located on the accessory side, rather than the mobile station side, and the sequence of events would be directed by the accessory controller 114.
  • mobile station controller 108 may first initiate authentication of external accessory 102 in order to verify that external accessory 102 is a valid accessory.
  • Many different methods of authentication as are known in the art may be used.
  • accessory control memory 116 contains a "secret code" which is transmitted to mobile station controller 108.
  • Mobile station controller 108 compares the "secret code" with a corresponding one stored in mobile station control memory 104. If the two codes match, then the external accessory 102 is presumed valid, and mobile station controller 108 proceeds as described below.
  • mobile station controller 108 may authenticate external accessory 102 using well known public and private key computations. Still other embodiments use other authentication 6 techniques.
  • the present invention is not intended to be limited by the type of authentication performed, which is a design choice based on the tradeoff between complexity of implementation and desired robustness of security.
  • mobile station controller 108 directs accessory controller 114 to initiate a download of the interface software contained in accessory interface memory 118.
  • Accessory interface memory 118 contains the interface software needed for the mobile station 100 to functionally interact with the specific external accessory 102.
  • Accessory interface memory may be any type of memory element as is known in the art.
  • accessory interface memory 118 is nonvolatile flash memory.
  • accessory controller 114 In response to the download request, accessory controller 114 reads the accessory interface software from accessory interface memory 118 and transmits it via interface 112 to mobile station controller 108.

  • mobile station controller 108 may check for errors in the download. For example, mobile station controller 108 may verify a checksum sent by accessory controller 114. Techniques for verifying the integrity of downloaded data are well known in the art, and the specific technique employed does not limit the present invention. If the download contained errors, mobile station controller 108 may direct accessory controller 114 to reinitiate download of all blocks containing errors, or alternatively the entire accessory interface software code.
  • mobile station controller 108 After a successful download of the accessory interface software code from accessory interface memory 118 in external accessory 102 to interface upload memory 106 in mobile station 100, mobile station controller 108 begins to execute the instructions contained in the accessory interface software.

If an attach is not detected, the flow continues to loop at decision 200 until an attach is detected. If an attach is detected, the flow proceeds to optional block 202 where authentication of the external accessory 102 is initiated by mobile station controller 108 as previously discussed with reference to FIG. 1. Because block 202 is an optional step, it is illustrated in FIG. 2 in dashed lines.
  • external accessory 102 is a valid accessory, i.e. one which authenticates properly.

Abstract

On décrit un procédé et un système qui assurent l'interface entre un dispositif (100) de communication sans fil et un accessoire externe (102). Le système comprend un détecteur (110) de branchement qui détecte le branchement du dispositif de communication sans fil et de l'accessoire externe (102). En réponse à la détection du branchement, un contrôleur (108) télécharge le logiciel d'interface de l'accessoire externe (102) dans le dispositif (100) de communication sans fil. Le dispositif de communication sans fil est ensuite relié à l'accessoire externe conformément à des instructions intégrées dans le logiciel d'interface de l'accessoire. Les besoins en capacité mémoire permanente pour la station mobile sont par conséquent réduits en raison du fait que le logiciel d'interface spécifique à l'accessoire est stocké dans l'accessoire externe (102) lui-même pour qu'il puisse être dynamiquement téléchargé dans la station mobile en fonction des besoins.
