Midamble được xác định thông qua một liên kết cố định giữa các midamble và mã channelization [7]. Midambles có sẵn cho PRACH / P là từ các thiết lập midamble dài, sử dụng Các midambles K đầu tiên được tạo ra bởi sự thay đổi bội số của chip W, trong khi midambles K thứ hai sử dụng một hằng thêm | 140 TDD Procedures Figure UE Registration on CS Domain Steps 1-2 and 10 are the same as those in CS Registration case. The others are described below 3 and 4. The UE sends a GMM GPRS Mobility Management message Attach Request to the SRNC which is relayed to the CN. 6. The Core Network sends an ATTACH ACCEPT NAS message to the S-RNC in RANAP DIRECT TRANSFER message. End-to-End Communication Procedures 141 Figure UE Registration on PS Domain 7. The S-RNC forwards the ATTACH ACCEPT NAS message to the UE in RRC DIRECT TRANSFER message. 8. UE sends an ATTACH COMPLETE NAS message to the S-RNC in RRC DIRECT TRANSFER message. 9. The S-RNC sends the ATTACH COMPLETE NAS message to the Core Network within the RANAP DIRECT TRANSFER message. 142 TDD Procedures Authentication and Security Figure shows how a CN authenticates the User and initiates the Ciphering for data and Integrity Protection for signaling messages processes. The CS and PS procedures are separately included in the same figure. UE Uu Node B lub C-RNC lur S-RNC Iu CN A 1 LT CS 1 1 i i C DIRECT TRANSFER - DCC 1 i H FACH 1 1. RANAP DIRECT TRANSFER 2.
