name: IMEISV
full_form: International Mobile Station Equipment Identity and Software Version number
context: on the UEâs IMEISV so that certain UEs which claim to support UEA1 shall have security established without ciphering (i.e. with UEA0), while other UEs which claim to support UEA1 shall have security established with ciphering (i.e. with UEA1). This procedure shall involve the SGSN/VLR retrieving the IMEISV from the UE before the security mode set-up procedure has started. If the above procedure to handle UEs which have faulty UEA1 implementations is implemented and the security mode set-up procedure results in security being established without ciphering (i.e. with UEA0) then the SGSN/VLR shall request the IMEISV from the UE for a second time immediately after the security mode set-up procedure has been completed. This second IMEISV request is integrity protected. If the IMEISV request is not successful, or if the second IMEISV received is different from the IMEISV received before the security mode set-up procedure was started then the connection shall be released.
description: IMEISV stands for International Mobile Station Equipment Identity and Software Version number, which is a unique identifier for mobile devices. It is used in the security mode set-up procedure to determine the level of security required for communication between the UE (User Equipment) and the network.
explanation: The text describes IMEISV as a parameter retrieved by the SGSN/VLR during the security mode setup, highlighting its function in determining security levels for device-network communication.
