Possible response(s)



+CMTLR: <subscribe>


+CMTLR: (list of supported <subscribe> values)


Set command enables Mobile Terminated Location Request (MT-LR) notifications to the TE. The parameter <subscribe> enables or disables notification by an unsolicited result code. It is possible to enable notification of MT-LR performed over the control plane or over SUPL or both. Relevant location request parameters are provided in the unsolicited result code +CMTLR: <handle-id>,<notification-type>,<location-type>,[<client-external-id>],[<client-name>][,<plane>].

This unsolicited result code is reported upon arrival of a Mobile Terminated Location Request. In order to differentiate multiple requests, every request is given a different <handle-id>. This ID is used when allowing or denying location disclosure with +CMTLRA.

Read command returns the current value of <subscribe>.

Test command returns the supported values as a compound value.
