BSS B11 Feature Description (New Features) 15 02 92: TRX dynamic power saving The principle of the feature is to switch-off the Power Amplifier (PA) bias of a given TRX, as soon as at least two consecutive TS are not transmitting. Indeed 2 TS are enough for the TRX to switch off then switch on its PA bias. It uses an “On the flight” principle, whereby the TRX detects whether data has to be transmitted over the air in the next two radio timeslots. The great advantages of this implementation are: • • • • • Applicability to all kinds of traffic: Voice, packet, signaling, Independence from the BTS configuration, Immediate reaction, providing gains 7 days a week 24 hours a day, No blocking, Easy O&M: No need to specify TRX de-activation periods. Thanks to this feature, the power consumption per TRX is reduced by around 25W when there is no traffic to be transmitted. At a BTS level, the association of TRX dynamic power saving, Power Control and Discontinuous Transmission in downlink brings around 25% saving on the global energy bill. 15 02 44: Support of two SUM boards per cabinet The MBI5/MBO2 cabinets can host two logical GSM BTS inside one cabinet as shared solution with standard modules, thereby allowing a very cost-effective introduction of 2GSM BTS in one MBI5/MBO2 existing cabinet. All common cabinet parts are managed by the 1st BTS via OMC reporting (e.g. External alarms etc.). Please find below an example for MBI5 case. Alcatel-Lucent confidential © 2011 All rights reserved.

Alcatel-Lucent implements BCCH hopping in its TWIN TRX. use and communication of its contents not permitted without written authorization. in order to re-align BCCH performances with already hopping TCH. Gains are expected to be between 2 and 3 dB. This brings diversity to the downlink path. which can be particularly useful in case of no hopping or hopping with few frequencies. Its principle is that a sequence of bursts of a given call is transmitted alternatively over 2 antennas. Alcatel-Lucent confidential © 2011 All rights reserved. Based on Antenna hopping principles.

The MSC connected to a same BSC belong to a “CS pool area”. Therefore limited interoperability issues between BSS and MSC Servers are expected. and together with Gb over IP. The main principle is that a BSC can be connected to several MSC. Alcatel-Lucent confidential © 2011 All rights reserved. Indeed if we take the example of an NGN network. .

This is needed in order to simplify the multiple signaling connections between BSC and MSC. the Operator can take the following benefits: • • • • Reduction of the signaling load: No inter-MSC handover and no LA Update take place as long as the MS stays inside the CS Pool Area. Just the traffic capacity of the failed MSC is lost and this loss is spread among all the BSC. Passing on and copying of this document. Better load balancing between the MSC. telecom service is no more completely lost for all the BSC. Increased service availability: In case of MSC site disaster. according to a BSS supplier dependent load sharing algorithm. . Easier Core network expansion: In case of traffic growth. Out of this feature. For the following accesses. Alcatel-Lucent implementation is based on A signaling over IP. the BSS decides which MSC of the CS pool area will handle the MS during its presence inside the CS pool area.BSS B11 Feature Description (New Features) MSC server3 M SC server6 M SC server5 MSC server2 MSC server4 MSC server1 CS pool area 1 Area 1 Area 2 CS pool area 2 Area 3 9130 BSC1 9130 BSC2 9130 BSC3 Area 5 Area 6 Area 7 9130 BSC5 9130 BSC6 9130 BSC7 At the first access of the MS inside the CS pool area.

This algorithm is A5/3. The BSS has now to decide which encryption algorithm to use on a per call basis. . Randomisation of filling bits in Layer 2 messages is a way to decrease the risks of hacking on the Air interface by replacing the fixed sequences of Layer 2 messages with random sequence of bits. By randomisation of Layer 2 filling bits. only one encryption algorithm was used inside a BSS: A5/2 or A5/1 (+ A5/0 meaning no encryption). Existing solution based on ODMC is adapted to deep analysis of a problem. there is an exchange of Layer2 messages between Mobile Station and BSS. Remark: It is not possible to accelerate reporting period for another PM type. ƒ avoid to degrade OMC-R response time for other users that would also like to access PM viewer. it is not allowed to keep the accelerated reporting period for more than 2 hours.

OMC-R user account management at Unix level can be centralized because OMC-R has already implemented in previous releases compatibility with such central LDAP database (with automatic regular synchronization mechanisms). The feature is currently available only for the edition of GSM-GSM adjacencies. Together with LDAP compatibility. 64 01 74: SEC Command line interface for external user management The integration of different management systems raises the need to consolidate the management of heterogeneous user accounts in one place. the SEC Command Line Interface allows a complete centralized user management for all OMC-Rs of your network. . This is of a great benefit in terms of administration cost (OPEX reduction) as well as in terms of security because password management for user account is also centralized.

All published views and reports are stored in a web file repository and can be available through a web page for any declared user like non-technical persons in a light web environment. While requesting the generation of a view or report. any operator can then have access to the generated view or report through the web viewer. . The proposed user interface also allows to the operator to export the results to MS-Excel®. When published. A typical use case of this feature is to automatically publish reports generated by scheduling (see also feature “78 12 40: QoS reports generation scheduling”) making them available to many people when they begin their working day. The published views and reports can be re-executed with a modification of the execution context: different start and stop time and/or with a subset of concerned topologic objects.
