ETSI ETSI TS 100 392-18-4 V1.2.1 (2015-07) 8 1 Scope The p
38、resent document defines Net Assist Protocol 2 that is optimized for TETRA air interface. It defines services: allowing information to be passed to a location determining entity also called MS (Mobile Station); allowing a location determining entity to request assistance information to an assistance
39、server. The information passed to the location determining entity by the assistance server, when relevant, reflects the content and format of the equivalent information (navigation data) which passes from satellites to the location determining entity. The protocol is capable of supporting more than
40、one position determining technology. Presently it covers multiple GNSS, and is extensible to all network positioning methods. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
