1. A method for verifying a broadcast message, the method comprising:
- receiving, at a device, a point-to-point message including information from a Location Server, wherein the point-to-point message conforms to a point-to-point protocol;
receiving the broadcast message at the device, from the Location Server, wherein the broadcast message comprises Assistance Data (AD) for location services of the device and a plurality of broadcast control parameters, wherein the broadcast message conforms to a broadcast protocol; and
verifying, by the device, validity of the AD using;
(1) at least one control parameter from the plurality of broadcast control parameters received from the Location Server via the broadcast message; and
(2) the information from the Location Server received via the point-to-point message.

Abstract
Various techniques are provided for Location Services (LCS) Assistance Data broadcast, for example for implementation in LTE and LTE-A systems. The embodiments described herein may use the LPP/LPPe positioning protocol, by making use of existing unsolicited Provide Assistance Data (PAD) messages. Embodiments avoid the need to define and implement a separate broadcast Assistance Data protocol. Additional exemplary embodiments for scheduling and verifying of the broadcast Assistance Data messages are described herein.
