Synchronization indication in networks
First Claim
1. A method, comprising:
- receiving, at a terminal apparatus, a transmission from a network, wherein the transmission includes global navigation satellite system time-cell time relation information, and wherein the transmission includes a network synchronization status flag;
performing, at the terminal apparatus, based on the network synchronization status flag, a determination of a synchronization status of the network from the transmission, wherein the transmission comprises assistance data, and wherein the synchronization status is that cells within the network are synchronized;
maintaining in a first cell within the network, at the terminal apparatus using said global navigation satellite system time-cell time relation information, accurate time based on the synchronization status of the network;
performing in the first cell within the network, at the terminal apparatus using said accurate time maintained in said first cell, global navigation satellite system satellite signal quick find;
maintaining in a second cell within the network, at the terminal apparatus with move of the terminal apparatus from the first cell within the network to the second cell within the network, using said global navigation satellite system time-cell time relation information accurate time based on the synchronization status of the network; and
performing in the second cell within the network, at the terminal apparatus using said accurate time maintained in said second cell, global navigation satellite system satellite signal quick find.

Abstract
Systems and methods provide a network'"'"'s synchronization status to a terminal when the terminal receives a transmission from the network. This network synchronization status can be indicated in accordance with various methods including, but not limited to the following: with a status flag in a network message; in a network capability indication; in a network'"'"'s positioning capability indication; cell/network time relation information; in a time relation information of different Radio Access Technologies; and implicitly with another parameter and/or by a request for a certain measurement. When the network'"'"'s synchronization status is determined, accurate time information/time assistance data can be maintained at the terminal.
