Capability obtaining and sending method, positioning server and device

A capability sending method, effected by a first device, comprising:

• sending integrity capability information to a positioning server, the integrity capability information being used for assisting the positioning server in performing a positioning operation;
• wherein, the first device is a terminal or an access network side node;
• wherein, the integrity capability information is used for indicating at least one of the following:
• a capability to support an integrity, the integrity being a measure of confidence in positioning accuracy;
• a capability to support monitoring the integrity of a target object, indicating that the first device is capable of monitoring the integrity of the target object;
• or
• a capability to support a first-device-based integrity application of the target object;
• wherein, the target object comprises:
• a first positioning manner and/or first positioning assistance data;
• wherein the capability to support the first-device-based integrity application of the target object comprises at least one of the following:
• an evaluation capability to support an evaluation of the integrity of the target object, indicating that the first device is capable of providing an integrity monitoring result of the target object;
• an exclusion capability to support an integrity exclusion of the target object, indicating that the first device is capable of excluding the target object not meeting an integrity requirement or retaining the target object meeting the integrity requirement;
• or
• a correction capability to support an integrity correction of the target object, indicating that the first device is capable of providing the integrity correction of the target object.

A device, the device being a first device, comprising:

• a transceiver, a memory, a processor, and a program stored in the memory and configured to be executed by the processor;
• wherein the processor is configured to execute the program to implement the following step:
• sending integrity capability information to a positioning server through the transceiver, the integrity capability information being used for assisting the positioning server in performing a positioning operation;
• wherein, the first device is a terminal or an access network side node;
• wherein, the integrity capability information is used for indicating at least one of the following:
• a capability to support an integrity, the integrity being a measure of confidence in positioning accuracy;
• a capability to support monitoring the integrity of a target object, indicating that the first device is capable of monitoring the integrity of the target object;
• or
• a capability to support a first-device-based integrity application of the target object;
• wherein, the target object comprises:
• a first positioning manner and/or first positioning assistance data;
• wherein the capability to support the first-device-based integrity application of the target object comprises at least one of the following:
• an evaluation capability to support an evaluation of the integrity of the target object, indicating that the first device is capable of providing an integrity monitoring result of the target object;
• an exclusion capability to support an integrity exclusion of the target object, indicating that the first device is capable of excluding the target object not meeting an integrity requirement or retaining the target object meeting the integrity requirement;
• or
• a correction capability to support an integrity correction of the target object, indicating that the first device is capable of providing the integrity correction of the target object.
