Table 2
It is pointed out that because RNC initiates to comprise two kinds of situations in the wireless link synchronization reprovision process, therefore, correspondingly in the step 101 pre-set operation and also comprise two kinds of situations.
First kind of situation,
Step 1011, when the reprovision by RNC control transmission carrying, according in the NBAP signaling at the value of Transport Bearer Request Indicator field, be changed to Bearer Requested with the value of Transport Bearer RequestIndicator field is default, or Bearer Not Requested.
Second kind of situation,
Step 1012, when by Node B on one's own initiative during the reprovision of control transmission carrying, according in the NBAP signaling at the value of Transport Bearer Request Indicator field, the value that also need pre-set TransportBearer Request Indicator field is Control by Node B.
In the step 101, also comprise the parameter that pre-sets the transmission bearer resource allocation.
Here, RNC allocates corresponding transmission bearer resource in advance for the transmission bearer that may change.Such as, when the type of transmission bearer was ATM, then RNC normally distributed the transmission bearer resource.When the type of transmission bearer was IP, then RNC also need distribute new transport layer address and Binding ID, and is filled up in the NBAP signaling.
After step 102, Node B receive the NBAP signaling, carry out corresponding processing according to the content of NBAP signaling.
Here, at step 1011,
After step 1021, Node B receive the NBAP signaling, under the control of RNC,,, carry out the transmission bearer reprovision passively, realize the synchronous reprovision of Radio Link such as Bearer Requested according to receiving corresponding field value in the NBAP signaling.Identical with the handling process of existing wireless link synchronization reprovision.
At step 1012,
After step 1022, Node B receive the NBAP signaling, promptly when Node B obtains the value Control by Node B of base station factor, judge reprovision, so by the carrying of Node B control transmission, Node B carries out the synchronous reprovision of Radio Link on one's own initiative, and finishes the synchronous reprovision of Radio Link.
Here, Node B determines whether to carry out the reprovision of transmission bearer according to factors such as traffic load, transport-type and types of service.
Below at 1022, carry out follow-up elaboration.
Step 1022 specifically comprises two kinds of situations, and first kind of situation is:
When Node B need carry out the reprovision of transmission bearer, Node B obtained corresponding transmission bearer resource, configuration transmission chain of command; Node B responds the NBAP signaling of RNC, and in the wireless link reconfigured transmission bearer information that is ready to complete after carrying reprovision in the message, returns to RNC.
RNC receive wireless link reconfigured be ready to complete message after, operate according to the wireless link reconfigured content that is ready to complete message.Because the wireless link reconfigured transmission bearer information of carrying in the message behind the reprovision that is ready to complete, therefore, RNC judges that preallocated transmission bearer resource is effective, transmits the configuration of chain of command.
Second kind of situation is:
When Node B did not need to carry out the reprovision of transmission bearer, Node B ignored the configuration of transmission bearer, did not carry transmission bearer information in the message wireless link reconfigured being ready to complete, and returned to RNC.
RNC receive wireless link reconfigured be ready to complete message after, operate according to the wireless link reconfigured content that is ready to complete message.Because wireless link reconfigured being ready to complete do not carried transmission bearer information in the message, therefore, RNC judges that NodeB does not carry out the reprovision of transmission bearer information, cancels preallocated transmission bearer resource.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
