Assisted GPS - Standards

Standards

AGPS protocols are part of Positioning Protocol defined by two different standardization body, 3gpp and Open Mobile Alliance (OMA).

  1. Control Plane Protocol - It is defined by 3gpp for various generations of mobile phone system. These protocols are defined for Circuit Switched Networks. Following positioning protocol has been defined.
    1. RRLP - 3gpp defined RRLP or Radio resource location protocol to support positioning protocol on GSM networks.
    2. TIA 801 - CDMA2000 family defined this protocol for CDMA 2000 networks.
    3. RRC position protocol - 3gpp defined this protocol as part of the RRC standard for UMTS network.
    4. LPP - 3gpp defined LPP or LTE positioning protocol for LTE Networks.
  2. User Plane Protocol - It is defined by OMA to support positioning protocols in Packet Switched Networks. Two generations of User plane Protocol have evolved.
    1. SUPL V1.0
    2. SUPL V2.0

Famous quotes containing the word standards:

    “The standards of His Majesty’s taste made all those ladies who aspired to his favour, and who were near the Statutable size, strain and swell themselves, like the frogs in the fable, to rival and bulk and dignity of the ox. Some succeeded, and others burst.”
    —Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)

    “With his brows knit, his mind made up, his will resolved and resistless, he advances, crashing his way through the host of weak, half-formed, dilettante opinions, honest and dishonest ways of thinking, with their standards raised, sentimentalities and conjectures, and tramples them all into dust. See how he prevails; you don’t even hear the groans of the wounded and dying.”
    —Henry David Thoreau (1817–1862)

    “Men are rewarded for learning the practice of violence in virtually any sphere of activity by money, admiration, recognition, respect, and the genuflection of others honoring their sacred and proven masculinity. In male culture, police are heroic and so are outlaws; males who enforce standards are heroic and so are those who violate them.”
    —Andrea Dworkin (b. 1946)
