Abstract
Techniques are described for providing assistance data corresponding to a plurality of access points (APs). The techniques include, in part, providing assistance data to a mobile device. The assistance data comprises group data that is common among the plurality of APs. The group data is associated with a group identifier (ID). The techniques further include providing the group ID and a set of AP-specific information for at least one of the plurality of APs. The group data may include information corresponding to a common grid, common location area and/or common characteristics of the APs.
Claims30
A method for providing assistance data corresponding to a first plurality of access points (APs), comprising:
- providing first assistance data to a mobile device, wherein the first assistance data comprises a first group data that is common among the first plurality of APs, the first group data being associated with a first group identifier (ID);
- and
- providing the first group ID and a set of AP-specific information for at least one of the first plurality of APs.
An apparatus for providing assistance data corresponding to a first plurality of access points (APs), comprising:
- means for providing first assistance data to a mobile device, wherein the first assistance data comprises a first group data that is common among the first plurality of APs, the first group data being associated with a first group identifier (ID);
- and
- means for providing the first group ID and a set of AP-specific information for at least one of the first plurality of APs.
A non-transitory computer readable medium for providing assistance data corresponding to a first plurality of access points (APs), comprising computer-readable instructions configured to cause a processor to:
- provide first assistance data to a mobile device, wherein the first assistance data comprises a first group data that is common among the first plurality of APs, the first group data being associated with a first group identifier (ID);
- and
- provide the first group ID and a set of AP-specific information for at least one of the first plurality of APs.
A method for obtaining assistance data corresponding to a plurality of access points (APs), comprising:
- receiving first assistance data from a device, wherein the first assistance data comprises a first group data that is common among the plurality of APs, the first group data being associated with a first group identifier (ID);
- receiving the first group ID and a set of AP-specific information for at least one AP among the plurality of APs;
- and
- determining AP vicinity information corresponding to the at least one AP based on the first group ID and the set of AP-specific information.
A device for providing assistance data corresponding to a first plurality of access points (APs), comprising:
- one or more processors;
- a communication system;
- and
- a memory device coupled to the one or more processors and storing machine-readable instructions, the machine-readable instructions, when executed by the one or more processor, causing the one or more processors to:
- provide, via the communication system, first assistance data to a mobile device, wherein the first assistance data comprises a first group data that is common among the first plurality of APs, the first group data being associated with a first group identifier (ID);
- and
- provide, via the communication system, the first group ID and a set of AP-specific information for at least one of the first plurality of APs.
A device for obtaining assistance data corresponding to a plurality of access points (APs), comprising:
- one or more processors;
- a communication system;
- and
- a memory device coupled to the one or more processors and storing machine-readable instructions, the machine-readable instructions, when executed by the one or more processor, causing the one or more processors to:
- receive, via the communication system, first assistance data from a device, wherein the first assistance data comprises a first group data that is common among the plurality of APs, the first group data being associated with a first group identifier (ID);
- receive, via the communication system, the first group ID and a set of AP-specific information for at least one AP among the plurality of APs;
- and
- determine AP vicinity information corresponding to the at least one AP based on the first group ID and the set of AP-specific information.
