User can report an incident through PSTN/PLMN/3G/NGN networks or web/email using fixed phone, cell phone, soft phones in desktop or laptops, IP phones and even though Fax machines. ECC Communication platform provides voice and non voice interface to receive these case reports from public and signals it to command center applications.The system treats all the heterogeneous network reports such as voice, SMS, email with same priority and maintains a single queue to handle each, one at a time. This way system adopts a unified approach of handling variety of alarms.The computer network is the backbone of ECC system. Below figure explains network connections of Huawei ECC communication platform. User can report an incident through PSTN/PLMN/3G/NGN networks or web/email.Following components will be equipped in Huawei emergency command center communication platform.Figre 5 2 Subsystem structure of an integrated command centerAs shown in the figure, both Voice and Non voice Emergency calls will be received and treated in a unified and collaborative way. The product U2980 acts as an access gateway (similar to PBX) to receive Fixed Phone, Mobile Phone and Fax calls to Emergency Command center. U2980 works as both Soft-switch and Automatic Call Distributor (ACD) to handle media calls from TDM (SS7, PRA) or IP (SIP) networks. U2980 provides media resource functionality for IVR operations and conference resources as well. Huawei ECC solution has inbuilt voice recording functionality (will be explained in later sections of the document in detail) which is also realized through U2980. U2980 is highly integrated media resource platform which can cater to Emergency contact centre requirements fully.Non Voice Alarm access gateway acts as an access device to send and receive multimedia messages. It supports Email, SMS, MMS, and Web Portal transactions by TCP/IP connections. The component complies with standard protocol interfaces such as SMTP/POP3 to connect to email server, SMPP to connect with SMSC, MM7 to connect to MMSC, etc. Also it supports receiving intelligent alarms generated by sensors like cameras over IP network complies with XML standard protocol interfaces.Access gateway acts as an access device to receive and analyze LBS system or GPS system or other 3rd party systems such as BOSS of telecom-operators for mobile location, vehicle location which equipped GPS devices and fixed phone subscribers’ information exchange.Management application server manages and controls all system configurations, basic data maintenance, user management and system access permission control. Functions like resources and catalog of incident management, user permission setting, etc…CTI (Computer Telephony Interface) platform connects U2980 /Non Voice Access Gateway and agent together. CTI platform comprises of a series of servers to provide the services such as call routing, queuing, recording, monitoring, and so on. One of the main usages of CTI is to specify the required services and collect user information. CCS is the core module of CTI platform which manages all the internal components of contact center. CTI provides the interface for implementing the service logic to control all resources.CTI Platform provides IVR functionality and APIs interfaces for service development. The CTI Platform connects and controls U2980 resources either through INTESS protocol which is Huawei proprietary or through CSTA which is an open standard protocol.CAD application server is the core component of whole solution which provides the agent Graphical User Interface to receive and process emergency calls. This subsystem will be integrated with GIS (Geographical Information System) and LBS (Location Based Services) modules which provide intelligent information to Call Takers and Dispatchers while processing an emergency incident. The Subsystem also controls report server to generate variety of statistical reports. The Report server can be configured to automatically generate necessary reports and share it to required stakeholders through emails. Supervisors can make use of these reports to execute area or region wise trend analysis.Dispatching subsystems allows operators to co-ordinate with different rescue agencies and facilitates, to offer necessary assistance to the victims. Huawei ECC solution provides extensive integration facilities to communicate and manage multiple emergency bureaus at the same time.Knowledge base server is a platform used by the operators to learn and share knowledge and skills of emergency situation handling. As per historical experiences Command department can also create temporary incident handling flows using knowledge base server to help newly joined agents with powerful and effective treatment plan for all kinds of incidents.Media Distribution Sever (MDS) functions like a gateway to integrate trunked radio system to ECC communication platform. MDS offers two types interfaces such as E1/IP interface to connect U2980 and air interface to direct communicate with Trunked Radio BTS. MDS will be used only to manage voice communications with radio terminals, for providing SDS functionality and other advanced applications Trunked Radio Access gateway will be used.NMS (Network Management System) helps to monitor the health of all critical components of the solution and provides user friendly interface to configure various subsystems.IP agent application includes agent desktop and IP phone. The desktop is connected to CTI by Huawei proprietary protocol and the IP phone connects to U2980 via SIP and RTP. The IP phone can be software client application in agent desktop or hardware IP phone.Huawei system supports agent (contact center) functionality in both centralized and distributed modes; distributed call center is one, that supports distributed deployment of resources, in this case, remote users will be serviced by local agents, which save the bandwidth between call center and remote systems.Storage Server is used to record the complete conversation between agent and user, and the same recorded file can be used as reference while dispatching a particular command. Storage Server is connected with U2980 by NFS protocol. U2980 records the agent conversation with alarm reporter and stores the recorded file in storage server. For playing announcements during the incident flow, U2980 fetches voice files from storage server and plays the prompts. Report server will generate and publish the report as configured by administrator.Proposed ECC solution supports capturing of the case details right from call reception till feedback collection when the case is resolved. The system offers a way to archive this information into the solution knowledge base which can be referred in future to handle similar emergency events. This functionality is embedded in Preplan management module.DB Server houses complete ECC solution application data and helps to extract necessary information to agents on need basis to process the incident smoothly. DB server uses UIDB (user information Database) as an application database to archive all the call details. It maintains and manages the user and statistical data which can be used for data consultation and call analysis. Al these components are connected each other over IP network. Using the accumulated data from DB server, commanders/supervisors can do comprehensive analysis on accident prone zone, crowded places, riot happening areas in cities, and can increase the security in such places to avoid emergencies to some extent. DB server also holds preplan system functions.5.3 IP Call Center(IPCC)The proposed contact center network can access the call from TDM network such as PSTN/PLMN via TUP/ISUP or access the call from IP networks such as NGN/3G via SIP/BICC protocol.Figure 5 3 Topology of Huawei IPCC solution for Niamey5.3.1 IPCC Solution ComponentsHuawei’s IPCC solution consists of the following components of its IP Contact Center solution: UAP, CTI and Service platform, Interactive Voice Response (IVR), IP Agent, DB Server/File Server.5.3.2 IPCC Solution DescriptionThe following section describes how Huawei’s solution would process different scenarios to provide the service to callers of CNB.5.3.3 Voice Calls Once a customer calls the published access code to reach Huawei call center, the call is forwarded from the PSTN/PLMN/NGN to Huawei’s UAP which is the ACD. On receiving the call, the ACD sends the call establish request to the CTI server. CTI server will make the routing decision based on the defined logic and send the call to either IVR or Manual Agent. Based on the routing logic if the call needs to be forwarded to the IVR, IVR treatment is provided to the caller based on the defined call flow. Once the caller has finished his interaction in the IVR and chooses to talk to an agent, CTI identifies an available agent based on the required skill and instructs UAP to forward the call to the agent. Huawei UAP transfers the call to the agent At the same time User information data will pop-up on the Agent Screen. Agent on answering the call will be connected to User. The User starts talking with the agent.5.4 Computer Aided Dispatch (CAD)CAD is one of the core components of ECC solution and provides various functionalities that deal with call-taking and dispatching operations. The system is designed using two different structures namely, Client/Server and Browser/Server, among which, both call taking and dispatching system are C/S architecture. Only the response unit especially police station uses the browser to access ECC system to receive assignments as well as to give feedback of incident handling.Using different software modules and work interfaces, CAD subsystem offers vital operations like emergency call reception, analysis, command and dispatch to serve emergency requests involving police, fire, health and other emergency bureaus.5.5 GIS Map Console FunctionsGIS map is an essential facility for emergency disposal.

Howerver, the different departments usually far away from each other, so how to connect them together, and provide them the video information of the frontline. So, Huawei video conference system can help you. Different from traditional and complicated videoconferencing solutions, Huawei Telepresense is integrated, immersive, and simple, conveying a new design concept for Huawei telepresence. Elegantly designed, the conference rooms of the Huawei Telepresence exhibit the essence of oriental classics and provide natural and friendly conference environments. Every detail, such as the table design, light source, wall color, and carpet material, is carefully considered and well combined with conference interaction so that participants can have fresh, unique, true, and face-to-face experiences.In this solution we propose to deploy 10 telepresence systems of all the Head office and branches. Which is shown in below:Figure 7 1 Huawei video conference solutionThe solution consists of Telepresence solution and VP8660MCU, GK/RM/Schedule web server, Telepresence systems, the whole system is based on IP network.1 sets of TP3006 is installed in the Head office; 9 sets of TP3006 are installed in the branch offices.7.1 Real-size HD VideoThe TP3006 uses the tri-lens camera provided by Huawei to capture images. By integrating the powerful codec capability of the dedicated telepresence terminal and the human engineering theory, the TP3006 shows the meeting participants in true-to-life dimensions on the three 65-inch TVs. Each screen displays the 1080p real-size images of two participants, making the participants feel that they are in the same meeting room.7.2 True-to-Life Conference ExperienceTraditional video conferences present simple voice and video communications. The TP3006, however, demonstrates a historic revolution from traditional video conferences to telepresence conferences by showing participants of different sites face to face in true-to-life dimensions.Figure 7 2 True to life experience of the Telepresence with three screenThe communications among people are not restricted to voices and images. The telepresence system captures and displays body languages and eye contact on screens. This improves user experience dramatically.7.3 48:9 Wide-Screen Conference ExperienceThe TP3006 provides excellent wide-screen conference experience. It adopts the tri-lens camera provided by Huawei to seamlessly stitch the three channels of 1080p images captured. In this way, six real-size HD images can be displayed on the screens.Compared with a traditional video conference, the TP3006 adopts the multi-image synchronization, image stitching, and environment integration technologies to solve the problems of dead zone in image stitching, ghost, small field depth, and unnatural background. Instead, it provides a wide field depth and allows a half-round table for participants.7.4 Full-Around Sound LocalizationThe TP3006 provides full-around sound localization. Participants in remote sites can immediately locate the speaker at any corner in the meeting room.Huawei extends its best practices in AEC, AGC, and ANS technologies to the TP3006. In addition, the TP3006 adopts the 22 kHz AAC-LD and unique hidden three-dimensional speaker design to provide cinema-level sound localization effects. You can easily locate the speaker at a remote site, making the communications smoother.7.5 Superior HD DataTaking the application requirements of HD data into full consideration, the TP3006 is designed with a 50-inch TV to display HD data so that you can view HD data easily while viewing the video of a remote site, which makes the overall design more elegant without affecting normal video communications. The TP3006 has the following features: Standard H.239 HD dual stream Supporting the standard H.239 protocol, the TP3006 can transmit two independent channels of video streams. After the Video Graphics Array (VGA) output interface on a computer is connected to the multi-functional socket on the desktop, both the conference video and the content displayed on the computer, such as a presentation, a Word document, a flash, or an HD picture, can be transmitted to a remote site simultaneously. In addition, the TP3006 supports a resolution of up to 1280 x 1024, which is the highest H.239 content resolution in the industry. In this case, the characters of 6.5 points in a Word document can be displayed clearly. Unique design The 50-inch display is hung under the middle 65-inch display and inclines in a certain angle to ensure the best views of six participants. This does not affect normal video communication. The 50-inch display blends in well with three 65-inch displays, which looks beautifully designed. Plug and play The TP3006 provides SXGA interfaces that support plug-and-play so that users can connect their laptops to the telepresence system and share data contents during conferences. HD data can be displayed automatically through the SXGA interfaces and the plug and play function. Superior conference experienceThe TP 3006 boasts superb HD data processing capability and high-quality videos by using the 50-inch professional plasma display, improving the conference experience.7.6 Integrated ControlThe TP3006 can easily manage telepresence sites in a unified manner through the RMCC provided by Huawei telepresence solutions. In addition, the TP3006 can automatically switch between the site being viewed and the site being broadcast and always ensure real-size and eye contact video quality. The TP3006 enables users to perform conference control between telepresence sites and between ordinary sites and telepresence sites, such as: Broadcasting a site Giving the floor to a site Viewing, adding or deleting a site Muting the speaker or microphone of a site Initiating or ending the call to a participant Enabling discussion, ending a conference Requesting for/releasing the chair control rightsDuring a conference, users can add a telepresence site to the continuous presence, thereby improving conference quality and achieving seamless integration with traditional conference application.8 ConclusionIn this document, Huawei provides a comprehensive technical proposal of national security for America.
