Method and apparatus for updating and providing satellite navigation message
First Claim
1. A method, comprising:
- receiving a download report from a receiver, the download report indicating presence or absence of respective information sections of sub-frames of a satellite navigation message currently stored by the receiver, the receiver receiving stored information sections of the satellite navigation message that are indicated as presence in the download report from a satellite;
determining whether to update a satellite navigation message database associated with a server using a subset of the stored information sections based on the download report from the receiver; and
in response to determining that the satellite navigation message database is to be updated using the subset of the stored information sections;
requesting the receiver to transmit the subset of the stored information sections to the server,receiving the subset of the stored information sections from the receiver by the server, andupdating the satellite navigation message database associated with the server based on the received subset of the stored information sections from the receiver.

Abstract
Aspects of the disclosure include a method for sharing satellite navigation messages. The method includes receiving a download report from a receiver. The download report indicates what portions of a satellite navigation message are currently stored by the receiver. The method also includes determining whether to update a satellite navigation message database associated with a server based on the portions of the satellite navigation message stored by the receiver. In response to determining that the satellite navigation message database should be updated, the method further includes requesting the receiver to transmit a subset of the satellite navigation message currently stored by the receiver to the server; receiving the subset of the satellite navigation message; and updating the satellite navigation message database associated with the server based on the received subset of the satellite navigation message.

9. An apparatus, comprising:
-
a storage device configured to store a satellite navigation message database; and control circuitry configured to; receive a download report from a receiver, the download report indicating presence or absence of respective information sections of sub-frames of a satellite navigation message currently stored by the receiver, the receiver receiving stored information sections of the satellite navigation message that are indicated as presence in the download report from a satellite; determine whether to update the satellite navigation message database using a subset of the stored information sections based on the download report from the receiver; and in response to determining that the satellite navigation message database is to be updated using the subset of the stored information sections; request the receiver to transmit the subset of the stored information sections, receive the subset of the stored information sections from the receiver, and update the satellite navigation message database based on the received subset of the stored information sections from the receiver. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A system, comprising:
-
a receiver configured to; receive and store information sections of sub-frames of a satellite navigation message from a satellite; and transmit a download report, the download report indicating presence or absence of respective information sections of the sub-frames of the satellite navigation message currently stored by the receiver; and a server configured to; receive the download report from the receiver; determine whether to update a satellite navigation message database associated with the server using a subset of the stored information sections stored by the receiver based on the download report from the receiver; and in response to determining that the satellite navigation message database is to be updated using the subset of the stored information sections stored by the receiver; request the receiver to transmit the subset of the stored information sections, receive the subset of the stored information sections from the receiver, and update the satellite navigation message database based on the received subset of the stored information sections from the receiver. - View Dependent Claims (18, 19, 20)
