Spreading factors vary from 4 to 512 in FDD UMTS to spread over

~5MHz. Spreading process gain can in expressed in dBs (Spreading

factor 128 = 21dB gain).

Interference Margin (WCDMA)

• WCDMA uses spreading factors 4 - 512 to spread thebase band data over ~5MHz band. Spreading factor indBs indicates the process gain Spreading factor 128 =

dBs indicates the process gain. Spreading factor 128 =

21 dB process gain). Interference margin is calculatedfrom that:

• Interference Margin =Process Gain - (Required SNR + System Losses)

• Required Signal to Noise Ration is typically about 5 dB• System losses are defined as losses in receiver path.

System losses are typically 4 - 6 dBs

1. Resources for transporting and manipulating the user data flows

reside in this layer.2. This node processes the end-user data and acts as an access switch

to the backbone switches/routers.

3. Over this interface the Gateway Control Protocol (GCP) is used.

4. This layer houses a number of servers that are responsible forcontrolling security, mobility management and set-up of calls andsessions.

5. Many end-user applications reside here.

6. This node handles establishment and control of end user IP services,as well as end user mobility management.

7. Authentication and ciphering data is generated here.

8. Handles call control for circuit switched services and controls circuitswitched related resources in the MGW.

9. This node manages the subscriptions and controls the roaming ofthe subscribers.

UMTS Attach traffic case

1.The MS sends an Attach Request, containing the P-TMSI and old RAI.2. If the MS is unknown to the SGSN server, the SGSN server sends an Identity

Request.

3. The MS responds with Identity Response (IMSI).

4. The SGSN server sends Authentication Request to the HLR (IMSI).

5. The HLR sends Authentication Information Ack (Authentication Triplets; RAND, SRES,and Kc).

6. The MS computes the signature SRES using RAND, the same subscriberauthentication key (Ki) and algorithms as AUC (Authentication Center, CipheringAlgorithm).

Algorithm).

7. The MS sends Authentication and Ciphering Response (SRES).8. The SGSN server sends an Equipment Identity Request to the MS.

9. The MS responds with its Mobile Identity.

10. The SGSN sends Check IMEI to the EIR, which responds with Check IMEI Ackmessage.

11. The SGSN server sends an Update Location message (SGSN number, SGSNaddress, IMSI) to the HLR.

12. The HLR sends Insert Subscriber Data (IMSI, UMTS subscription data) to the SGSNserver.

13. If all checks are successful, the SGSN server returns an Insert Subscriber Data Ackmessage to the HLR.

14. The HLR acknowledges the Update Location message by sending Update Location Ack to the SGSN server.

15. The SGSN sends an Attach Accept message to the MS.

16. MS acknowledges with Attach Complete.

17. If the Attach Complete cannot be accepted, the SGSN server returns an Attach

Reject (IMSI, cause) message to the MS.

UMTS PDP Context Activation traffic case

28. decembar 2005. 151

UMTS PDP Context Activation traffic case1. The MS sends an Activate PDP Context Request (PDP Address, APN, QoS).2. The SGSN server validates the Activate PDP Context Request using the PDP type,

PDP address, and the APN.

3. If no GGSN MGW address can be derived the SGSN server rejects the PDP contextactivation request.

4. If the GGSN MGW address can be derived, the SGSN server creates a Tunnel ID(TID) for the requested PDP context.
