Methods, Network Node and Wireless Device for Handling System Information

A method, performed by a network node of a radio network, for enabling a wireless device to access the radio network, wherein system signatures are associated with corresponding system information configurations that can be used for accessing the radio network in a first area, and wherein at least some of the system signatures are reused in a second area as associated with system information configurations which are different than in the first area, the method comprising:

• indicating that at least one system information configuration stored in the wireless device is invalid and should not be used.

A network node of a radio network, the network node being configured to enable a wireless device to access the radio network, wherein system signatures are associated with corresponding system information configurations that can be used for accessing the radio network in a first area, and wherein at least some of the system signatures are reused in a second area as associated with system information configurations which are different than in the first area, the network node comprising:

• processing circuitry;
• memory containing instructions executable by the processing circuitry whereby the network node is operative to:
• indicate that at least one system information configuration stored in the wireless device is invalid and should not be used.

A method, performed by wireless device, for enabling access to a radio network, wherein system signatures are associated with corresponding system information configurations that can be used for accessing the radio network in a first area, and wherein at least some of the system signatures are reused in a second area as associated with system information configurations which are different than in the first area, the method comprising:

• receiving, from a network node of the radio network, an indication that at least one system information configuration stored in the wireless device is invalid and should not be used;
• and
• making the at least one invalid system information configuration unusable in the wireless device.

A non-transitory computer readable recording medium storing a computer program product for enabling a wireless device to access a radio network, wherein system signatures are associated with corresponding system information configurations that can be used for accessing the radio network in a first area, and wherein at least some of the system signatures are reused in a second area as associated with system information configurations which are different than in the first area, the computer program product comprising software instructions which, when run on processing circuitry of a network node of the radio network, causes the network node to:

• indicate that at least one system information configuration stored in the wireless device is invalid and should not be used.
