Liquid Radio - Making radio networks active, adaptive and aware





Liquid Radio architecture shares resources such as antenna information across a broad area of the network, as well as balances traffic evenly over different bandwidths. It allows radio coverage and capacity to flow to wherever users need it most. Liquid Radio also enables operators to seamlessly integrate 3GPP radio access with Wi-Fi to use unlicensed spectrum.  Liquid Radio improves network efficiency by boosting capacity, balancing loads, enhancing QoS, raising uplink capacity for smartphones, and identifying and avoiding smartphone signaling. It also adds small cell capacity and unifies heterogeneous networks, as well as implementing award-winning self-organizing network (SON) functions to simplify network operations. High energy efficiency is achieved by low power consumption, integration of Rf to the antenna, minimized Rf losses and by an adaptive and cognitive radio network that can proactively align the ‘active’ cells with user demand to save energy.

Nokia Siemens Networks has also announced its innovative Flexi Multiradio Antenna System as part of the Liquid Radio architecture. Nokia Siemens Networks Liquid Radio adapts the capacity and coverage of your networks to match fluctuations in user demand. It maximizes network performance and minimizes operating costs by automating operations. It includes built on Software Suites, Single RAN Active Antenna Systems, Baseband Pooling and Unified and SON-enabled Heterogeneous Networks.

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. ·  ...

PS core network

Image
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 i...
