In the prior art, cell private channel (CELL-DCH, CELL-Dedicated Channel) UE of state uses the enhancing dedicated channel to carry out in the transmitting uplink data process, base station node B can be distributed a sign that strengthens dedicated channel for UE, promptly strengthen dedicated channel Radio Network Temporary Identifier (E-RNTI, E-DCH Radio Network Temporary Identifier).Use this to identify the transmitted power of adjusting UE between UE and the NodeB.
UE for the CELL-DCH state, E-RNTI is that UE distributes by NodeB, and Dedicated NBAP signaling procedure (promptly be directed to every and eat dishes without rice or wine to connect the signaling that Radio link sets up) by Iub interface, NodeB is notified to RNC with E-RNTI, the information that to distribute E-RNTI by RNC, Radio Resource control (RRC, Radio Resource Control) signaling by the Uu interface is notified to UE.
In the prior art, the UE that uses the E-DCH channel to carry out the CELL-FACH state of transmitting uplink data also needs E-RNTI, uses this to identify the transmitted power of conflicting the solution process and adjusting UE between UE and the NodeB.
UE for the CELL-FACH state, if distributing the mode of E-RNTI to carry out E-RNTI according to existing UE to the CELL-DCH state distributes, because the UE of CELL-FACH state belongs to common condition, NodeB of the prior art can not store its contextual information for the UE of this state, and is not used in the Dedicated NBAP signaling of CELL-FACH state UE on the Iub interface yet.If still allow the E-RNTI allocation entity of NodeB as CELL-FACH state UE, need in NodeB, store the contextual information of CELL-FACH state UE so, and need be the NBAP signaling that the UE of CELL-FACH state introduces new special use on Iub interface.Can increase the complexity of NodeB like this, also run counter to the basic principle of the UE of CELL-FACH state as common condition.
Distribute for the E-RNTI of CELL-FACH state UE,, then do not have the above-mentioned problem that NodeB is introduced complexity and introduces the Dedicated NBAP signaling if allow RNC as the distribution node of its E-RNTI.Yet, because the E-RNTI of UE is unique in cell range, also be that E-RNTI is the part of local resource, if the E-RNTI of CELL-FACH state UE is distributed by RNC, and the E-RNTI of CELL-DCH state UE is distributed by NodeB, means two nodes of the resource distribution of sub-district at network side, if whole E-RNTI resources are regarded as a resource pool, this resource pool just needs separated into two parts so, and a part is positioned at RNC, and a part is positioned at NodeB.
So when UE from CELL-FACH state transition to the CELL-DCH state, perhaps by CELL-DCH state transition during to the CELL-FACH state, because variation has taken place in the distribution node of E-RNTI, the E-RNTI of UE in the state transition process must change so, can not be reused E-RNTI in the state transition process, can the scheduling of resource be affected greatly like this, can't realize level and smooth state transition.
