Positioning integrity in wireless networks

Second apparatus, comprising:

• a mobile communication transceiver configured to operate in a mobile communication network,
• wherein the second apparatus is configured to transmit with the mobile communication transceiver an information message to a first apparatus or a group of first apparatuses of the mobile communication network, the information message comprising an integrity information describing an integrity status of the GNSS signals in a geographical or logical area in which the first apparatus or group of first apparatuses is located,
• wherein the second apparatus is configured to receive a report of at least one parameter from the first apparatus, wherein the at least one parameter is determined by the first apparatus based on GNSS signals received by the first apparatus and in dependence on the integrity information, wherein the report of the at least one parameter comprises a quality and uncertainty,
• wherein the information message is a first information message, wherein the integrity information is a first integrity information,
• wherein the second apparatus is configured to receive from a third apparatus a second information message comprising a second integrity information describing the integrity status of the GNSS signals in the geographical or logical area in which first apparatus is located,
• wherein the first integrity information transmitted with the first information message is based on the second integrity information.

Method for operating a first apparatus, the method comprising:

• receiving GNSS signals,
• operating in a mobile communication network,
• determining at least one parameter based on the received GNSS signals,
• receiving a first information message from a second apparatus of the mobile communication network, the first information message comprising a first integrity information describing an integrity status of the GNSS signals, and
• determining the at least one parameter in dependence on the first integrity information and reporting the at least one parameter taking into account the first integrity information, wherein the report of the at least one parameter comprises a quality and uncertainty,
• wherein the first integrity information received with the first information message is based on a second integrity information of a third apparatus, the second integrity information describing the integrity status of the GNSS signals in the geographical or logical area in which first apparatus is located.

Method for operating a second apparatus, the method comprising:

• operating in a mobile communication network, transmitting an information message to a first apparatus or a group of first apparatuses of the mobile communication network, the information message comprising an integrity information describing an integrity status of the GNSS signals in a geographical or logical area in which the first apparatus or group of first apparatuses is located,
• wherein the information message is a first information message, wherein the integrity information is a first integrity information,
• receiving from a third apparatus a second information message comprising a second integrity information describing the integrity status of the GNSS signals in the geographical or logical area in which first apparatus is located,
• wherein the first integrity information transmitted with the first information message is based on the second integrity information.
