A system and method of providing a Push To All (PTA) service enables a PTA service terminal having limited resources to efficiently perform a multi session, while performing a PTA service such as Push To Talk (PTT), Push To Video (PTV) or Message Session Relay Protocol (MSRP) with a second PTA terminal via an already established session, by rejecting another session requested by a third terminal upon a service type of the session being the same as a service type of the already established session, and by accepting the session upon the service type of the session being different from the already established session.

Providing push to all (PTA) service

In a Push-To-All (PTA) service system and method enabling selective designation of data transmission targets, a transmitting PTA terminal requests a selective data transmission to a PTA server using a receiver-designated Talk Burst Control Protocol (TBCP) message containing information about some receiving PTA terminals participating in the same session as the transmitting PTA terminal, and the PTA server transmits data received from the transmitting PTA terminal to designated receiving PTA terminals by referring to the information contained in the receiver-designated TBCP message. Thus, a selective data transmission can be performed within one PTA session.

A method for continuous ethylene polymerization under high pressure using a polymerization reaction zone comprises a primary reaction zone and a secondary reaction zone wherein the secondary reaction zone has a length of 1.5-6.5 times the length of the primary reaction zone and a cross-sectional area of 1.2-4 times the cross-sectional area of the primary reaction zone. Ethylene is fed continuously into the primary reaction zone at the starting point of the primary reaction zone. Low temperature initiator alone, or an initiator mixture containing mainly low temperature initiator is introduced into the primary reaction zone at the starting point of the primary reaction zone. Initiator alone or an initiator mixture is introduced into the secondary reaction zone at two or more different points of the secondary reaction zone. Ethylene polymer products of various physical properties are produced with high productivity, while the pressure drop is minimized.
