Disclosed arc a messaging system. apparatuses circuits and methods of operation thereof. A messaging client device is adapted to receive an impermanent message and to manage the received message in accordance with a message management policy associated with the message. An impermanent messaging server is adapted to validate said messaging client device as complying with message management policies prior to authorizing transmission of the message to said messaging client device.

Methods and devices for redefining a time alignment timer of a wireless communication network include determining that a Radio Resource Control, RRC, connection from the UE to a network node is operating in Connected Discontinuous Reception, CDRX, mode. In response to determining that the RRC connection is operating in CDRX mode, an initial message include a Protocol Feature Type, PFT, and a User Equipment Type and Software Version Number, UE-TSVN is transmitted, to the network node. In response to the initial message, a handshake message including the PFT, a downlink Protocol Message Type, PMT, indicating a Time Alignment Timer Definition, TATDEF, message type, and a Protocol Message Body, PMB, associated with the TATDEF message type that including one or more values for redefining a time alignment timer is received from the network node.

Techniques for group message thread link administration are described. In one embodiment, an apparatus may comprise a client front-end component operative to receive a join invitation command associated with a group message thread from an administrator client device, the group message thread associated with a message thread identifier, the message thread identifier identifying the group message thread on a messaging system; and send a join invitation link to the administrator client device; and a group management component operative to generate a join invitation link in response to the join invitation command, the join invitation link comprising a thread invitation identifier, wherein the thread invitation identifier is a hash of the message thread identifier. Other embodiments are described and claimed.

Various communication systems may benefit from suitable interworking. For example, certain fifth generation short message service systems may benefit from interworking with long term evolution short message service deployments in a visited public land mobile network. A method can include receiving, at a network element, an attach request from a user equipment. The method can also include using an internal policy to find a short message service function that resides at the network element. The method can further include using an address of the short message service function for providing short message service to the user equipment.

A first user equipment (UE)—during a real time text (RTT) communication session with a second UE—may make a control function available to a local user of the first UE, who may invoke the control function to break up his/her RTT content within organized conversation bubbles. In an example process, after displaying first text character(s)—which was input by the local user—within a first conversation bubble designated for the first UE (or the local user thereof), the first UE may detect an invocation of the control function, followed by additional user input requesting to type one or more second text characters. Invocation of the control function prior to the additional user input requesting to type the second text character(s) may cause the first UE to display the second text character(s) within a second conversation bubble designated for the first UE, rather than the first conversation bubble.

A method of proactively defending combustible property against fire ignition and flame spread in the presence of wild fire. The method involves establishing wireless communication between a GPS-tracking anti-fire (AF) chemical liquid spraying system, and a wireless communication network supporting a network database. The GPS-tracking anti-fire chemical liquid spraying system is used to spray an environmentally-clean anti-fire chemical liquid over the exterior surfaces of a GPS-specified combustible parcel of property, and generating a GPS-coordinate and time/date stamped data records pertaining to the application of the environmentally-clean anti-fire chemical liquid spray over the exterior surfaces of the GPS-specified combustible parcel of property. The GPS-coordinate and time/date stamped data records are transmitted over the wireless communication network for storage in the network database. A computing system is used to access the GPS-coordinate and time/date stamped data records from the network database, so as to verify that the GPS-specified parcel of property has been fire-protected on particular date by virtue of the GPS-specified property being sprayed with the environmentally-clean anti-fire chemical liquid so as to proactively inhibit fire ignition and flame spread in the presence of wild fire.
