Description

This interface is for various cellular things (GSM and/or CDMA) that aren't really applicable to other protocols.

Signals

IMSIChanged (s: IMSI)

Parameters

  • IMSI — s
    • The new IMSI value. This may be an empty string in the case where the IMSI is being reset or removed.
Emitted when the IMSI for the connection changes. This sort of thing is rare, but could happen on cellular phones that allow hot-swapping of SIM cards. In the case of SIM swapping, this signal would be emitted twice; the first time while the SIM is being ejected (with an empty string), and the second time after a new SIM has been inserted (assuming that the IMSI can be determined from the new SIM).

Properties

Accessed using the org.freedesktop.DBus.Properties interface.

MessageValidityPeriod — u

Read/Write

Define how long should the service centre try message delivery before giving up, failing delivery and deleting the message. A value of 0 means to use the service centre's default period.

The value specified is in seconds. Note that various protocols or implementations may round the value up (eg. to a minute or hour precision). The maximum validity period may vary depending on protocol or provider.

Connections with this interface SHOULD provide this property as a parameter of the same (fully-qualified) name to ConnectionManager.RequestConnection, with the DBus_Property flag. For connections managed by the AccountManager, this property SHOULD be set via the Account Manager as follows:

UpdateParameters({ "org.freedesktop.Telepathy.Connection.Interface.Cellular.MessageValidityPeriod": new_validity_period }, [])

The AccountManager provides change-notification, as long as all other clients cooperate by using it instead of setting this property directly.

OverrideMessageServiceCentre — b

Read/Write
Added in 0.19.UNRELEASED. Previously, as an undocumented feature, setting MessageServiceCentre to the empty string caused the SIM's default SMSC to be used.

If True, SMSes will be sent via the service centre specified by MessageServiceCentre. If False, the SIM's default SMSC will be used, ignoring the value of MessageServiceCentre.

Rationale:

It could be desirable for a configuration interface to remember the user's previous choice of custom SMSC, even if it's not in use. This boolean allows that choice to be saved as an account parameter by Mission Control, rather than the UI needing to save it elsewhere to be restored if the user wants to reactivate it.

Connections with this interface SHOULD provide this property as a parameter of the same (fully-qualified) name to ConnectionManager.RequestConnection, with the DBus_Property flag. For connections managed by the AccountManager, this property SHOULD be set via the Account Manager as follows:

UpdateParameters({ "org.freedesktop.Telepathy.Connection.Interface.Cellular.OverrideMessageServiceCentre": True }, [])

The AccountManager provides change-notification, as long as all other clients cooperate by using it instead of setting this property directly.

MessageServiceCentre — s

Read/Write
Changed in 0.19.UNRELEASED. This property's value is now ignored unless OverrideMessageServiceCentre is True.

Address for the messaging service centre. Typically (as is the case for GSM's SMSC), it's the ISDN / telephony address (ie. a phone number). If OverrideMessageServiceCentre is False, this property's value should be ignored by the CM in favour of the SIM's default SMSC.

Connections with this interface SHOULD provide this property as a parameter of the same (fully-qualified) name to ConnectionManager.RequestConnection, with the DBus_Property flag. For connections managed by the AccountManager, this property SHOULD be set via the Account Manager as follows:

UpdateParameters({ "org.freedesktop.Telepathy.Connection.Interface.Cellular.MessageServiceCentre": new_smsc_address }, [])

The AccountManager provides change-notification, as long as all other clients cooperate by using it instead of setting this property directly.

IMSI — s

Read only

The International Mobile Subscriber Identifier, if it exists. This would originate from a SIM card. If the IMSI is unknown, this will contain an empty string ("").

(Permalink)

MessageReducedCharacterSet — b

Read/Write

Determines whether SMSes containing characters that do not fit into a 7‐bit GSM character set should be sent as UCS‐2, or lossily recoded. If False (which SHOULD be the default), messages will be sent with no loss of fidelity (at the potential financial cost of using twice as many SMSes); if True, the message will be recoded in an implementation‐specific way to fit into a country‐specific GSM reduced character set.

Connections with this interface SHOULD provide this property as a parameter of the same (fully-qualified) name to ConnectionManager.RequestConnection, with the DBus_Property flag. For connections managed by the AccountManager, this property SHOULD be set via the Account Manager as follows:

UpdateParameters({ "org.freedesktop.Telepathy.Connection.Interface.Cellular.MessageReducedCharacterSet": new_value }, [])

The AccountManager provides change-notification, as long as all other clients cooperate by using it instead of setting this property directly.
