To achieve these goals, a kind of system that in the cdma2000 standard group communication system, realizes the group high-speed data business that the present invention proposes, its content comprises: when portable terminal is initiated a group data service call, this user uploads data and sends to PDSN by the base station, and process PDSN copies to cluster server, cluster server is according to the target group of group calling, and the user initiates the group data service call in group, by PDSN data is distributed to the interior user of group then.
The method that native system adopts comprises following key step:
(1) initiates the group data call request based on the PTT terminal of cdma2000.
(2) a high speed uplink complement channel is set up for this user in the base station, and sets up PPP (Point-to-Point Protocol, the point-to-point protocol) connection (that is, data communication connects) between this user and the PDSN, and keeps this connection.
(3) cluster server is initiated user in the paging group according to the target group of group calling by the base station.
(4) after the user responded in the group, a shared down high speed complement channel was distributed for these users in the base station, and the PPP that sets up between each user and the PDSN connects.
