©Copyright 2006-2011 Mobile Computing Promotion Consortium (MCPC)MCPC TR-002 Hands-Free Profile 1.5 Guideline Version 1.511. IntroductionThe Car-Communication-Application-Promotion group (CCAP) is concerned that Car-WG profiles maynot provide sufficient definition to assure interoperability of Bluetooth devices supporting these profiles.CCAP believes that this application guide for the Bluetooth Hands-Free applications will improve theinteroperability between handheld devices and the car, and help implementers understand the Hands-Freeprofiles for user convenience. This guideline provides:- Recommended values of parameters- Recommended sequence charts- Basic philosophy- Option usage- New scenarios not included in the HFPThe intent is that this guideline be applied to the application layer above the Hands-Free Profile (HFP).The CCAP may also provide additional guidelines in the future such as the Phonebook Access Profile(PBAP), the Message Access Profile (MAP) etc. and future versions of these profiles.CCAP released the Application Guideline Ver1.0 for the Hands-Free Profile Ver1.0 in June 2003. Thisguideline is based on the Hands-Free Profile Ver1.5. There indicates newly added and changed featuresfrom the Hands-Free Profile Ver1.0 and the CCAP Application Guideline Ver1.0.NOTE: CCAP does not intend to replace or enhance the Hands-Free Profile. CCAP intends this guidelinecan complement the Hands-Free Profile.1.1 Target systemThe figure below shows a system diagram that this guideline specifies. The minimum functionality of theHands-Free unit (HF) is a speaker, microphone and control switch. The Display and Sound Generator areoptional.Display (opt.)Name: Ichiro SuzukiNo.090-1234-5678Speaker(std.)Hands-Free unitSoundGenerator(opt.)BluetoothMicrophone(std.)Control Switch(std.)Switch[HF]Phone[AG]8

CCAP Application Guideline 1.0 adds“signal” and “battchg” indications in Appendix A. HFP 1.5 covers these indications and the further statusindications.1.3.2 Three Way CallingHFP 1.0 specifies the basic Three Way Calling features. HFP 1.5 adds some parameters of controlcommands and result indications for matching the status between the AG and the HF.9

©Copyright 2006-2011 Mobile Computing Promotion Consortium (MCPC)MCPC TR-002 Hands-Free Profile 1.5 Guideline Version 1.511.3.3 Enhanced Call StatusThese features inform the HF of each call status in the AG. The HF can detect either the AG has multiplecalls or not, and what kind of calls the AG have and which status each call is through a query commandand unsolicited result codes. These features are effective for matching the status between the AG and theHF in Three Way Calling.1.3.4 Enhanced Call ControlThese features are extension of Three Way Calling and shall be considered all together.1.3.5 Response and HoldCCAP Application Guideline 1.0 specifies the same features in Appendix A. HFP 1.5 covers thesefeatures and a query command for the AG status.The Response and Hold features depend on the cellular network. All operators and phone manufacturersin Japan implement these features into their networks and products.The Response and Hold features seem to be similar to the Three Way Calling. However these twofeatures are absolutely different. The Response and Hold features are applicable only for an incoming call.The AG with a held incoming call does not accept an additional incoming call and an outgoing call. Thecellular network denies any additional calls if the AG is in the Response and Hold state. On the other handthe Three Way Calling commands shall be applied when the AG has multiple calls. The Three Way Callingfeatures shall not affect a held incoming call through the Response and Hold commands.Therefore the Response and Hold state shall be independent with the held state through the Three WayCalling features either in the AG or the HF.1.3.6 Subscriber Number InformationCCAP Application Guideline 1.0 specifies the same feature in Appendix A.10

(It is implementation dependant.)(For example, some users may set specific time parameters on the AG, which define theduration until the ongoing call is terminated.)- Maintain the ongoing call.When the new Service Level Connection is established and there is an ongoing call, the AG is responsiblefor choosing whether the call is transferred from the AG to the HF or not. This is left as an implementationchoice for the AG design. (It should be noted that the existing ongoing call is not always the same as thecall before link loss). Following implementations are examples.(1) The ongoing call may be transferred to the HF by user judgment and operation.(2) If the existing ongoing call is same as the one before link loss by AG judgment, the audio connectionmay be transferred to the HF autonomously.- User may choose whether the audio connection is transferred to the HF autonomously or not.8

©Copyright 2006-2011 Mobile Computing Promotion Consortium (MCPC)MCPC TR-002 Hands-Free Profile 1.5 Guideline Version 1.51 Appendix A1. AbstractThis document describes the guideline how to transfer the phonebook from the cellular phone or the PDAto the Hands-Free Car Kit using Bluetooth wireless technology.Generally, we already have some of the solutions to support phonebook transfer as follows.(1) vCard with OBEX(2) AT command(3) Custom application for exchanging phonebook dataIn this document, we select and show the guideline of (1). Because vCard and OBEX is alreadystandardized as OPP (Object Push Profile) in the Bluetooth SIG, it can be utilized for the multipurpose. Thistechnology can resolve the problem of sorting or selecting Japanese character data (ex. Furi-gana, whichmeans sound).3

Phonebook transfer features of the cellular phoneRegarding the phonebook transfer of the cellular phone, the following features shall be supported as theOBEX Client/Server operations. This table shows which feature shall be Mandatory(M), Option(O), Not-Recommended(N/R) or Not-Applied(N/A). If the cellular phone does not have phonebook storing ability, itssupported feature is N/A.“OBEX Authentication” in the table below is a kind of certifying operation in order to identify whether theremote device is the correct target requested to connect when OBEX is initiated. The details of OBEXAuthentication are described in the next section.IrMCLevelOBEX Authentication(Note-1)Support OperationOBEXClientSupportOBEXServerSupportLevel 1 (Note-1)OBEX PUT object in InboxO N/R M MLevel 2OBEX PUT Entire Object StoreM O M MLevel 2N/RM OOBEX GET Entire Object Store(Note-3)MLevel 3N/RM OOBEX GET/PUT Objects by Static Indices(Note-4)OLevel 4OOBEX GET/PUT Objects by Unique Indices, M M(Note-2)Change Log Support, Change Counter SupportONote-1 Regarding OBEX Authentication,- Level 1: Object transfer with an indefinite device. OBEX Authentication is not recommendedto operate in this case.- Level 2/3: Object transfer between devices of same user. OBEX Authentication isrecommended to operate in this case. (Refer to IrMC Errata 990714 No.5)- Level 4 is based on the Synchronization Profile Specification of Bluetooth SIG. OBEXAuthentication shall be operated.Note-2 When Synchronization is realized, the Server shall support OBEX Authentication. However, theClient features so that the cellular phone initiates OBEX Authentication might be Optional.Note-3 Since supporting the PUT Client features enables entire object transfer and providing both thePUT/GET Client features makes user operations complicated, OBEX Authentication is notrecommended to support for Level 2.Note-4 Since providing the PUT/GET Client features with specified Static Index makes user operationscomplicated, OBEX Authentication is not recommended to support for Level 3.Note-5 When Level 1 is initiated, input value in the Name header of transfer objects shall avoid onewhich can be confused with Level 2 object name, such as “pb.vcf” etc.3. OBEX AuthenticationThe cellular phone shall support OBEX Authentication. During OBEX session establishment, the cellularphone shall execute Authentication Sequence specified in the section 3.1 and use Authentication Keyspecified in the section 3.2.4

©Copyright 2006-2011 Mobile Computing Promotion Consortium (MCPC)MCPC TR-002 Hands-Free Profile 1.5 Guideline Version 1.51 Appendix A6.4 3.1 Authentication Sequence“Normal Authentication” allows IrMC Level 1/2/3 OBEX operations. This enables accessing data in“telecom/####” except “/luid/#####”. “Normal Authentication” shall be used for Level 2/3 OBEXAuthentication when the cellular phone is the Client.When the PUT Client/Server transfers only one object, it is not needed to execute OBEXAuthentication. However, when the remote device requests OBEX Authentication, the local device shallrespond with “Normal Authentication”. An example of “Normal Authentication” (PUT operation) is shownbelow. The details shall be referred in IrOBEX version 1.2, IrDA Object Exchange Protocol version 1.2,Infrared Data Association.Example.

The device of Server side requests the Session Key during“Normal Authentication”. The value of the Session Key shall be same between theClient and the Server. The Session Key is canceled during OBEX session release afterend of object transfer.Example. “Normal Authentication” sequence and the Session Key usageUser inputs:Session Key1234User inputs:Session Key1234ClientNormal Auth.

OPP : Object Push ProfileOPP is already defined by the Bluetooth SIG, which was released on 22 February 2001. Most of currentBluetooth embedded cellular phones have OPP available, CCAP would like to utilize this as the phonebooktransfer.The phonebook format is defined to adopt vCard ver2.1 when using the telephony application in thisspecification.OPP defines the roles, the server and the client. CCAP strongly requests that the AG should be the clientand the HF should be the server at the point of the phone functionality.8. 5. vCardAs defined in OPP, the format of the phonebook should be followed ver.2.1 of vCard. However,especially considering in Japanese situation, the HF Car Kit has to handle some of the ver3.0 of vCardbecause the property of “Sort_String” is used for information of “Furi-gana” in vCard 3.0. The followingrequirements or attentions should be considered for implementation.8.1 5.1 PropertyProperties of vCard for a standard cellular phone, which shall be careful to be implemented, are listedbelow. Multiple phone numbers for a name entry of vCard can be stated. However, this guideline doesnot specify the number of phone numbers.Property Name Support Note Ref.: IrMC1.1VERSION Version M VCard 2.1 MN Name M MSOUND or Sort_String Furi-gana M Use the extended parameter.

©Copyright 2006-2011 Mobile Computing Promotion Consortium (MCPC)MCPC TR-002 Hands-Free Profile 1.5 Guideline Version 1.51 Appendix A9. 6. TransferCCAP recommends to support the following object transfer.(1) One object transferThe OPP client can select just one object to be transferred. The way to select the object isimplementation dependant. The selection by the user‟s operation would be preferable. The client mayclose OBEX session after the transfer.(2) Plural objects transferThe OPP client can select plural objects to be transferred. The way to select the objects isimplementation dependant. The selection by the user‟s operation would be preferable. In thisfunction, the user‟s explicit operation to close OBEX session might be required on the OPP client.(3) Entire objects transferThe OPP client can select whole phonebook in the client.In the specification of IrMC, OBEX authentication shall be executed when entire data push. However,it‟s defined in OPP that this is not executed. In this guideline, CCAP recommends that OBEXauthentication be not executed because Bluetooth authentication is already done and we think muchof the convenience for the user.10. 7. Others(1) Additional properties for Japanese marketThe following properties would be considered because the conventional cellular phones alreadyimplement them.- Memory number- Group number- Group name- Secret codeThey are defined in MCPC GL-003.12
