WCDMA RAN ( Radio Access Network)

WCDMA RAN

WCDMA RAN is a part of the 3rd generation (3G) mobile system, and comprises:
  • OSS-RC
  • RNC
  • RANAG
  • RBS
WCDMA RAN has interfaces towards the Core Network (CN), and towards the external Network Management Systems (NMS).
WCDMA RAN provides Radio Access Bearers (RAB) between the CN and the subscriber's User Equipment (UE) for speech, data, and multimedia services.

The Network Elements (NEs) RNC, RANAG, and RBS provide and manage the data links between WCDMA RAN and the UE. The links between the NEs in WCDMA RAN carry the user data within WCDMA RAN. These physical links are also used to carry O&M data. See figure for an overview of WCDMA RAN.

SCFT - Single Cell Function test

-
Single Cell Function test SCFT is for verifying whether individual BTS works well or not, by making a single cell function test of BTS hardware and software. Essential items to be tested are as follows: 1) BTS Transmitter Output Measurement Test 2) Initial parameter establishment (Pilot PN/System ID/Site ID/Frequency, Neighbor List) 3) Call Origination and Termination Test 4) Softer Handoff Test/Antenna installation check (Direction, Tilt, Transmission Line) 5) Single Cell Coverage Test 6) Noise Floor Test 7) Parameter check.

Troubleshooting for GSM KPIs (SD Block & SD Drop)

-
KPIs to be monitored: ·             SD Blocking ·             SD Drop SDCCH Channel: ·    SDCCH channel is a dedicated channel which is using for LAC updation, Call Setup, SMS in Ideal mode. It works in UL & DL SD Blocking: ·    SD Blocking means that you are not getting SD resource for the call origination. When MS connects with Network then RACH and AGCH are provided. After AGCH, SDCCH is provided but if SDCCH is not provided at this time due to some problem or due to unavailable of SD by BSC. KPI Formula in Ericsson: ·             SDCCH CONGESTION = (CCONGS / CCALLS) * 100 ·             CCONGS - Congestion counter. ·             CCALLS - Channel allocation attempt counter (on SDCCH). Reason for SD Blocking: ·             LAC Boundary ·             High Volume of SMS ·             SD utilization is high ·             Time Slot fault

PS core network

The PS core network consists of two parts, the traditional General Packet Radio Service (GPRS) core network and the new Evolved Packet System (EPS) core network. The PS core network connects mobile subscribers to Packet Data Networks (PDNs) such as the Internet, corporate networks or operator services networks.  a functional overview of the PS core network. Logical entities and interfaces are shown in black and form a 2G/3G network, while the blue boxes and lines in Figure  show the LTE/EPC related parts. The LTE/EPC network can be regarded as an extension and evolution of existing 2G/3G networks. From a node implementation perspective, there is no strict border between the two networks. The corresponding logical entities of GPRS and EPS networks can be deployed concurrently in Ericsson PS core nodes, such as the SGSN-MME and EPG; these are marked in red. In addition, Ericsson GPRS nodes can be upgraded with EPC functionality by software only. Network evolution is support
