Modal verbs terminology In the present document “shall“, “shall not“, “should“, “should not“, “may“, “need not“, “will“, “will not“, “can“ and “cannot“ are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of provisions).
20、 “must“ and “must not“ are NOT allowed in ETSI deliverables except when used in direct citation. ETSI ETSI TS 103 544-8 V1.3.0 (2017-10)5 1 Scope The present document is part of the MirrorLinkspecification which specifies an interface for enabling remote user interaction of a mobile device via anoth
21、er device. The present document is written having a vehicle head-unit to interact with the mobile device in mind, but it will similarly apply for other devices, which provide a colour display, audio input/output and user input mechanisms. The present document specifies location service based on SBP
22、(Service Binary Protocol) framework. The service is used to provide better location data in car environments. Note that this service provides high-level abstraction of location compared to com.mirrorlink.GPS service, which focuses on NMEA based GPS data. 2 References 2.1 Normative references Referen
