TECHNICAL SPECIFICATION

Performance characteristics

Provides 100 000 + requests per hour in a low-cost basic configuration, enough for the commercial deployment of successful Mobile Location Based services. More capacity can be obtained by upgrades, increasing the capacity up to 700 000+ requests per hour, enough for any imaginable mass-market service.

Typical response time of the system is between 1.0 – 4.0 seconds during undisturbed and normal working conditions.

Accuracy

Unique high accuracy technology enables innovative new Mobile Location Services for the mass-market, giving a consistent competitive advantage to the operator.

Deployment options

A fully redundant architecture (optional) with a second hot-stand-by system ensures the best system availability.

Product architecture

Modular architecture enables easy future expansion of the system. All the components of the basic system and upgrades are contained in one 19” rack.

Security

Full system security can be provided by firewalls and secure connections. Complete authentication and authorisation of Client Applications is provided.

Operations, Administration and Maintenance

Management and configuration functionality provides a complete local and remote system administration and control functionality supporting both CLI (Command Line Interface) and HTTP interfaces. Statistics and reports enable local and remote system monitoring and continuous tuning of the system behaviour. SNMP support is provided for fault alarms.

Standards

A fully GSM standard (ETSI/3GPP, Open Mobile Alliance) compliant design makes Locus A-MLC a ready-to-deploy solution to any GSM network including any multi-vendor network.

Integration

Complete customisation services are available to integrate Locus A-MLC into the operator infrastructure, enabling seamless co-operation with other existing and future systems. Integration is possible with Privacy Database or Charging System, for example.

Protocols

The following protocols are supported.

1. Open Mobile Alliance (OMA) Mobile Location Protocol or HTTP or HTTPS from Client Applications

1. Standard Location Immediate Request (SLIR) from the Client Application

2. Standard Location Immediate Answer (SLIA) to the Client Application

3. The Locus A-MLC supports single locations requests for Mobile Subscriber Identity (MSID) only, without location subscriptions or geographical definitions/restrictions.

2. Web-based Graphical User Interface (GUI) over HTTP or HTTPS from Administration Workstations

3. Command Line Interface (CLI) over Telnet or SSH from Administration Workstations

4. Simple Network Management Protocol (SNMP) towards Network Management System

1. SNMP version 2 is supported for handling SNMP Traps

5. Statistics over File Transfer Protocol (FTP) or Secure Copy (SCP)

1. Statistics Reports (files) can be retrieved

6. Mobile Application Part (MAP) over SS7 towards the Core Network

1. The Core Network is required to provide support for MAP version 3 in ITU-T SS7. The following MAP operations and associated procedure may optionally be supported by the core network:

1. Any Time Interrogation (ATI) receipt and response by the HLR

2. The following MAP operations and associated procedures must be supported by the core network:

1. Provide Subscriber Information (PSI) receipt and response by the MSC/VLRs

2. Send Routing Info For SMS (SRI-SM) receipt and response by the HLR

3. Mobile Terminating Forward Short Message (MT-FSM) receipt and response by the MSC/VLRs

7. Cell Data over FTP or SCP from the Cell Database

8. Charging Data (optional customisation)

9. Privacy Check (optional customisation)

Network configuration information

Network configuration information can be imported from a range of different systems, allowing fully automated information flow from a network configuration management system in order to guarantee the relevance of network configuration data in Locus A-MLC.

Physical Interfaces

Two Fast 100baseT Ethernet connections are required.

A single 75-ohm physical SS7 E1 connection towards the Core Network is required. If a 120-ohm connection is used, a balancing unit is required.

Addressing

IP addressing

Locus A-MLC hosts are addressed in the IP network. For basic configuration, two IP addresses are required. For upgrades, more IP addresses may be needed.

SS7 addressing

Each Locus A-MLC host is addressed with a separate Signalling Point Code (SPC) and Global Title in the SS7 network. Locus A-MLC hosts use Global Title for routing. For paging using SMS, each Locus A-MLC host is addressed with a separate SMSC address as well. For SS7 signalling towards Signalling Transfer Points (STPs), each Locus A-MLC host is equipped with one SS7 PCI-board that supports two E1 interfaces with up to 32 signalling channels per PCI-board. The PCI-board supports BNC and RJ45 cables. The E1 interfaces do not use Cyclic Redundancy Check (CRC).

Physical Packaging

Mechanics

The HW components of the Locus A-MLC are rack mounted using a standard 19-inch rack. It is possible to physically co-locate the HW components of the Locus A-MLC and Client Application(s) within the same 19-inch rack system.

Power Supply

External AC power: 100-240V, 50-60 Hz.

Environment

The system is designed for housing in a protected tele/datacom environment.
