Abstract

Systems and methods are provided allowing for a vendor-defined payload in a standardized user-plane location solution/protocol, where proprietary extension support is introduced into one or more standardized solutions. In accordance with a first embodiment, a location payload consists of structures for transferring requests, assistance data, measurements and positioning instructions. Therefore, a proprietary extension is included in each of these structures so that, for example, proprietary assistance data can be requested in an appropriate structure. In accordance with another embodiment, a proprietary extension is introduced at the highest abstraction level. For example and in an actual implementation, a vendor can define that in the beginning of the proprietary payload, the proprietary extension is defined, whether the proprietary payload contains a request, assistance, etc.

First claim

What is claimed is:

1. A method of providing location services by a location server, comprising:
receiving, by the location server, from a mobile device a request for location assistance information, wherein the request for location assistance information uses a payload structure in a standardized user plane location protocol, wherein the payload structure has at least one structure for at least one of requests, assistance data, measurements, positioning instructions, or combinations thereof, wherein the payload structure comprises at least one proprietary extension structure, wherein the at least one proprietary extension structure allows for transmitting of proprietary assistance data and is added such that all location information in the payload structure, including the proprietary assistance data, is within a single framework in the user-plane location protocol, and wherein the proprietary extension structure is configured to accommodate transmitting of proprietary assistance data originating from one or more of a plurality of vendors, wherein accommodating transmitting of proprietary assistance data from one or more of a plurality of vendors comprises accommodating assistance data from different vendors, wherein the proprietary assistance data is vendor-specific assistance or location information; and
in response to the request for assistance information from the mobile device transmitting the assistance information to the mobile device using the payload structure comprising the proprietary extension structure.

2. An apparatus, comprising:
at least one processor; and
at least one memory including computer program code,
the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following:
receiving, by a location server, from a mobile device a request for location assistance information, wherein the request for location assistance information uses a payload structure in a standardized user-plane location protocol, wherein the payload structure has at least one structure for at least one of requests, assistance data, measurements, positioning, instructions, or combinations thereof, wherein the payload structure comprises proprietary extension structure, wherein the at least one proprietary extension structure allows for transmitting of proprietary assistance data and is added such that all location information in the payload structure, including the proprietary assistance data, is within a single framework in a user-plane location protocol, and wherein the proprietary extension structure is configured to accommodate transmitting of proprietary location assistance data originating from one or more of a plurality of vendors, wherein accommodating transmitting of proprietary assistance data from one or more of a plurality of vendors comprises accommodating assistance data from different vendors, wherein the proprietary assistance data is vendor-specific assistance or location information; and
in response to the request for assistance information from the mobile device, transmitting the assistance information to the mobile device using the payload structure comprising the proprietary extension structure.

3. A method of requesting location services from a location server, comprising:
transmitting, by a mobile terminal, to the location server a request for location assistance information, wherein the request for location assistance information uses a payload structure in a standardized user plane location protocol, wherein the payload structure has at least one structure for at least one of requests, assistance data, measurements, positioning instructions, or combinations thereof, wherein the payload structure comprises at least one proprietary extension structure, wherein the at least one proprietary extension structure allows for requesting of proprietary assistance data and is added such that all location information in the payload structure, including the proprietary assistance data, is within a single framework in the user-plane location protocol, and wherein the proprietary extension structure is configured to accommodate requesting of proprietary assistance data originating from one or more of a plurality of vendors, wherein accommodating requesting of proprietary assistance data from one or more of a plurality of vendors comprises accommodating assistance data from different vendors, wherein the proprietary assistance data is vendor-specific assistance or location information; and
receiving, by the mobile terminal, from the location server in response to the request, assistance information transmitted from the location server to the mobile terminal using the payload structure comprising the proprietary extension structure.

4. The method of claim 3 , wherein the at least one proprietary extension structure comprises an information element having a vendor-specific payload.

5. The method of claim 4 , wherein the vendor-specific payload is identified by a vendor identifier.

6. The method of claim 4 , wherein the at least one proprietary extension structure comprises more than one vendor-specific payload, the vendor-specific payloads being distinguished by vendor identifiers.

7. The method of claim 4 , wherein the vendor-specific payload comprises decoding instructions in addition to data.

8. The method of claim 3 , wherein the at least one proprietary extension structure comprises an information element having a vendor identifier and at least one of a placeholder for a message type and an assistance data identifier.

9. The method of claim 8 , wherein the at least one proprietary extension structure comprises more than one vendor-specific payload, the vendor-specific payloads being distinguished by vendor identifiers and either the message type or the assistance data identifier.

10. The method of claim 8 , wherein the message type refers to a type of the at least one of the requests, assistance data, measurements, positioning instructions, or combinations thereof to be transmitted via the user-plane location protocol.

11. The method of claim 8 , wherein interpretation of the placeholder for the message type is specified by a vendor.

12. The method of claim 8 , wherein the vendor identifier and either the assistance data identifier or the message type are indicative of a particular service provider and at least one of a navigation model, time assistance, reference location, an atmosphere model, a differential correction, sensor assistance, acquisition assistance, position information, high-accuracy position information, multi-frequency multi-Global Navigation Satellite System measurement data, global positioning system-related data, computationally-generated measurements, sensor measurements, route information, and waypoint information.

13. The method of claim 3 , wherein the addition of the at least one proprietary extension structure occurs at each of the at least one structure for transmitting the at least one of the requests, assistance data, measurements, positioning instructions, or combinations thereof.

14. An apparatus comprising:
at least one processor;
memory storing a program of instructions;
wherein the memory storing the program of instructions is configured, with the at least one processor, to cause the apparatus to perform at least the following:
transmitting, by a mobile terminal, location server a request for location assistance information, wherein the request for location assistance information uses a payload structure in a standardized user plane location protocol, wherein the payload structure has at least one structure for at least one
