At first, the service access process supposes that this business is the business that user terminal is initiated.
Step 1: the base station receives the service connection request that user terminal sends by wave point;
Step 2: the base station sends to the wireless access server with user ID and connectivity request message by Iub interface;
Step 3: the wireless access server judges according to the current resource behaviour in service of system whether this business can insert; If can insert, execution in step 4, otherwise, execution in step 5;
Step 4: the wireless access server is set up a Radio Resource control connection by Iub interface and wave point and user terminal; And this user's user ID and service requesting information sent to service control server in the core net, execution in step 6 by the Iu-c interface;
Step 5: finish this access procedure.
Step 6: receive service response or refusal information from service control server, if core net responded should business access, then execution in step 7, otherwise, execution in step 5;
Step 7: the wireless access server is by Iub interface and wave point informing user terminal, and execution in step 8, begins to carry out the configuration of Radio Resource;
Step 8: the wireless access server receives the RAB information that current business should adopt by the Iu-c interface from core net;
Step 9: according to the behaviour in service of Radio Resource in the current system, determine the allocation of radio resources scheme that current business should adopt, and the content of this scheme is distinguished informing base station and wireless access gateway by Iub interface and Iuc interface;
Step 10: base station and wireless access gateway are carried out the distribution of radio bearer according to the allocation of radio resources scheme of appointment; Execution in step 11 then, begin to carry out professional transmission;
Step 11: it is synchronous that professional transmission needs that at first Iu-u interface, Iug interface and wave point are carried out time unifying, transport channel synchronization and wave point respectively;
Step 12: the user data transmission of between Iu-u interface and wave point, carrying out uplink and downlink by wireless access gateway and base station;
In the process of business transmission, the wireless access server also sends external circule power control information and measures indication to base station and user terminal by Iub interface and wave point; And from Iub interface reception measurement result; Adjust the configuration state of Radio Resource then according to the processing of measurement result and estimated channel quality; Again the wireless resource information that reconfigures is sent to base station and wireless access gateway respectively by Iub interface and Iuc interface, base station and wireless access gateway just can be according to the new wireless resource configuration that receives for adjusting the radio-resource-configuration situation of user terminal like this.
When the user is belonging to the moving between cells of two different base stations under the wireless access server controls, the wireless access server passes through the information of Iur interface exchange adjacent base station and sub-district, and sends the traverse measurement request and receive measurement result to the user by Iub interface and wave point; The wireless access server sends to the base station with mobility management information by Iub interface, transmits relevant user data and the control information transmission of mobility by IuNB interface or Iub with the Iur interface between the base station; If SRNS (service radio network system) reorientation, then between the base station, need to transmit the information relevant with mobility, also need between the wireless access server to transmit with this user's business and control relevant information, also may transmit this user's business datum and beared information respectively with between the wireless access gateway that two wireless access servers link to each other by the Iuw interface by the Iur interface.
When this business stopped, the wireless access server discharged all Radio Resources relevant with this business, and sends professional terminate-ack information to user terminal and core net.
Can realize that through said process a data business transmits in control provided by the invention and Radio Access Network that business function separates, and then realize that based on the Radio Access Network that separates with business function of control communication becomes possibility between the explanation user terminal, the practicing of Radio Access Network that promptly this control with advantages such as message transmission rate height, network construction form are reasonable separates with business function becomes possibility.
