Assistance data specifications and protocols for navigation systems

A non-transitory computer-readable storage medium including program code, which when executed by at least one processor provides operations configured to perform at least:

• establishing a streaming secure user plane location session in a network, wherein the streaming secure user plane location session includes a continuous transfer of at least one of a service, an assistance data, and a measurement data to a remote device, wherein the streaming secure user plane location session continues for a predetermined period of time, and wherein the remote device comprises at least one of a secure user plane location-enabled terminal and a secure user plane location-enabled server;
• modifying, during the streaming secure user plane location session, the continuous transfer of the at least one of the service, the assistance data, and the measurement data to the remote device, wherein the continuous transfer is modified to include a different type and/or an additional type of service, a different type and/or additional type of assistance data, and/or a different type and/or an additional type of measurement data, and wherein the continuous transfer is modified without terminating the streaming secure user plane location session and/or establishing another streaming secure user plane location session;
• determining whether the network supports the user plane location protocol signaling;
• determining whether any service restrictions are present, when the network is determined to support the user plane location protocol signaling;
• and
• in response to there being no service restrictions present, streaming, at a requested service level, the at least one of the service, the assistance data, and the measurement data to the remote device.

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:
• establish a streaming secure user plane location session in a network wherein the streaming secure user plane location session includes a continuous transfer of at least one of a service, an assistance data, and a measurement data to a remote device, wherein the streaming secure user plane location session continues for a predetermined period of time, and wherein the remote device comprises at least one of a secure user plane location-enabled terminal and a secure user plane location-enabled server;
• modify, during the streaming secure user plane location session, the continuous transfer of the at least one of the service, the assistance data, and the measurement data to the remote device, wherein the continuous transfer is modified to include a different type and/or an additional type of service, a different type and/or additional type of assistance data, and/or a different type and/or an additional type of measurement data, and wherein the continuous transfer is modified without terminating the streaming secure user plane location session and/or establishing another streaming secure user plane location session;
• determine whether the network supports the user plane location protocol signaling;
• determine whether any service restrictions are present, when the network is determined to support the user plane location protocol signaling;
• and
• in response to there being no service restrictions present, stream, at a requested service level, the at least one of the service, the assistance data, and the measurement data to the remote device.
