The 3rd step, after NodeB receives above-mentioned HS-DSCH type 2 Frames, at first preserve dedicated H-RNTI, special E-RNTI, the HS-DSCH ability rating of UE and the corresponding relation between the E-DCH ability rating of UE.Then table look-up and find corresponding transport block size index according to the true HS-DSCH ability rating of transmission block size and UE, and arrive UE by the HS-SCCH channel notification; UE, according to the transport block size index on the HS-SCCH channel and HS-DSCH ability rating, is mated and is obtained the transmission block size that NodeB will send, and on HS-PDSCH channel subsequently, message is set up in correct reception RRC connection.

The 4th step, UE responds RRC connection setup complete message according to real E-DCH ability rating to RNC at up direction after receiving that message is set up in the RRC connection, and NodeB receives and is transmitted to RNC according to the real E-DCH ability rating of UE equally.

Above example is applicable to the initial access process that UE initiates, and comprises the cell updating course after cell reselection.By above-mentioned processing, in the initial access process that UE initiates, make and can correctly transmit data between NodeB and UE strengthening under the CELL_FACH state.

Example 2, strengthen the CELL_FACH state in the situation that UE moves out, and NodeB discharges the special E-RNTI of UE.

The first step, UE is at up direction according to E-DCH ability rating launch position update request, and NodeB receives and is transmitted to RNC according to the E-DCH ability rating of UE, then by RNC, is transmitted to core net.

Second step, after core net is received the position updating request of UE, send the position renewal at down direction to RNC and accept message, RNC accepts message by the renewal of the position of core net and is encapsulated by HS-DSCH type 2 data frame formats, but do not carry dedicated H-RNTI, E-RNTI, HS-DSCH ability rating information and E-DCH ability rating information in HS-DSCH type 2 Frames, and the New IE Flags field in HS-DSCH type 2 Frames of encapsulation is set to full 0;

The 3rd step, NodeB issues UE according to the HS-DSCH ability rating information of UE after receiving that message is accepted in the position renewal, and UE receives according to HS-DSCH ability rating information equally;

The 4th step, core net is initiated the Iu release command to RNC, and RNC initiates the RRC connection release message to UE, and this message is packaged into to HS-DSCH type 2 data frame formats issues NodeB, and New IE Flags field is set to 0;

The 5th step, after NodeB receives the RRC Connection Release, issue UE according to the HS-DSCH ability rating, and UE receives according to the HS-DSCH ability rating;

The 6th step, after UE receives the request of RRC Connection Release, complete message according to E-DCH ability rating information by the RRC Connection Release and send to NodeB, and NodeB receives and be transmitted to RNC according to the E-DCH ability rating information of UE.

The 7th step, the special E-RNTI that RNC discharges this UE by chain of command message status indication notice NodeB, after NodeB receives notice, discharge the corresponding relation of this E-RNTI, H-RNTI and ability rating information.

In above-mentioned processing, the RRC of UE connects and to have obtained release, thereby needs to discharge in NodeB the context semanteme about this UE.When UE proceeds to other states from the CELL_FACH state, when in these states, no longer applicable HS-DSCH and E-DCH transmit, RNC also can discharge special E-RNTI and context semanteme corresponding to this UE by chain of command message informing NodeB.
