HSDPA

HSDPA stands for “High Speed Downlink Packet Access”. As the name suggests, this is a piece of UMTS functionality designed to deliver downlink packet data at very high data rates. It is a release 5 feature. It achieves its aim by using the following techniques:

•Use of shared channel conceptRather than constantly allocating and deallocating dedicated channels to individual users, users share a high bandwidth channel – the HS-DSCH (High Speed Downlink Shared Channel). This allows the system to operate with a “fat pipe”

LG

Flexi BTS Licensing principles

Pool license concept• Operator orders in advance a big

amount (e.g. need for 1 month rollout) of unallocated licenses

• NetAct operator distributes licenses during NE integration via NSN License Generator (LG)

• Simplified logistics, reduces site visits for capacity expansion

No floating licenses• BTS licenses tied with the physical

System Module HW, NOT with the site.• When you move the box you also

move the licenses with it.Long term licenses• Exception: also short term licences for

channel capacitySW Feature licenses also possible

• Current models RNC196, RNC450 and RNC2600 (RU10)

WCDMA Radio Resource Management:

Management of traffic channels and control channels can be divided into:

Resource manager

Admission control

Load control

Power control

Handover control

Packet scheduler

Telecom functions:

Security functions: integrity checking, ciphering

User plane processing towards CS and PS core network (for example management of radio access bearers (RAB))

Radio network layer control plane processing

Service area broadcast

Location services: LCS Cell Coverage Based (RTT) with Geographical Coordinates

In the Cell Coverage Based locationing method, the location of the UE is estimated on the basis of its serving cell. Information about the serving cell is obtained, for example, by paging, location area update, cell update, URA update or routing area update.

RNC performance measures

• RNC capacity is licensed as– Iub PS data throughput

– AMR capacity

– Number of carriers, BTS or cells

• RNC load is calculated as total data rate of all users

6 7RNC Variants in RAS06

RNC196 RNC450

•With RAS05.1 we get a new RNC product variant “RNC450”

•At the same time also RNC196 can be upgraded to higher capacity.

•RNC450 comes with RAS05.1 but RNC196 can be used with RAS05 and RAS05.1

•RAS06 does not bring any new RNC types

Number of Simultaneous HSDPA users

• HSPA traffic uses shared channel where the peak rate throughput is shared by all users in the same cell.

• When the number of user's transmitting data simultaneously increases, the average throughput per user decreases.

RAS06 - SW Configurable Coverage Optimized RNC450

• High capacity RNC450 enables also coverage optimized solutions

• RNC450 (step 2 and 3) can be configured either for:

– Capacity optimized solution

– Coverage optimized solution

• No HW changes are required

• Solution control will be done with a SW license

• Several steps are possible:
