8.6.2Service states

Depending on the service state, an additional textual output is generated (refer also to the response examples):

'Searching' - The MS is searching, but could not (yet) find a suitable cell. This output appears after restart of the MS or after loss of coverage.

'No connection' - The MS is camping on a cell and registered to the network. The service state is 'idle', i.e. there is no connection established or a dedicated channel in use.

'Cell Reselection' - The MS has not yet lost coverage but is searching for a better cell, since the cell reselec- tion criterion is fulfilled.

'Limited Service' - The MS is camping on a cell but not registered to the network. Only emergency calls are allowed. The MS enters this state, for example, when

-no SIM card is inserted, or PIN has not been given,

-neither Home PLMN nor any other allowed PLMN are found,

-registration request was not answered or denied by the network (use command AT+CREG to query the registration status),

-authentication failed.

8.6.3Notes

The parameters LAC and cell are presented as hexadecimal digits, the remaining parameters are composed of decimal digits.

If the radio cell changes during a connection, the parameters PWR, RXLev and C1 of the 'Serving Cell' part cannot be updated under certain conditions and therefore, are displayed as "-" (for conditions see also AT+CREG). This is because the MS does not update the cell selection and reselection parameters since, in this mode, they are not relevant for operation. When the connection ends, and the mobile is back to IDLE mode, correct values will be given.

If the radio cell changes during a connection, it normally takes 1 or 2 seconds to update the parameters cell,
