Abstract:
Disclosed are methods and systems for broadcasting positioning assistance data (PAD) to subscriber devices in a wireless network. In one aspect, a location server may encode and optionally cipher PAD and transfer the encoded and optionally ciphered PAD to a base station for broadcast in a system information block (SIB) in at least one cell. In an aspect, the PAD may be segmented by the location server or by the base station with each PAD segment broadcast in a separate SIB. Cipher key information for ciphered PAD may be transferred by the location server to a network node and provided to a subscriber device using a mobility management procedure. A subscriber device may receive, optionally decipher and decode PAD in SIBs broadcast by a base station and may use the PAD to assist location of the subscriber device.

Claim (Index 23):
A user equipment (UE) for using broadcast location assistance data in a network, comprising:\n a wireless transceiver; and one or more processors configured to: obtain first ciphering key parameters received at the wireless transceiver from a network node in the network during a mobility management procedure; obtain a System Information Block (SIB) periodically broadcast from a base station within at least one cell for the base station received at the wireless transceiver, the SIB comprising ciphered and encoded first positioning assistance data for the least one cell for the base station, and an indication of ciphering; decipher the encoded first positioning assistance data based on the first ciphering key parameters and the indication of ciphering; decode the deciphered and encoded first positioning assistance data; and determine location information for the UE based, at least in part, on the deciphered and decoded first positioning assistance data.
