[0029] Embodiment 1

[0030] Figure 1 This is a flow chart of a method for dispatching and communicating urban railways provided in the first embodiment of the present invention. This embodiment is applicable to the case where the dispatching and communicating services are integrated with the non-dispatching and communicating services during the dispatching and communicating process of urban railways. The method can be executed by an urban railway dispatching and communicating system. The urban railway dispatching and communicating system can be implemented in the form of hardware and / or software. The urban railway dispatching and communicating system can be configured in a central server. Figure 1 As shown, the method includes:

[0031] S110. Transmitting the access request initiated by the calling terminal to the access layer through the ubiquitous network layer; wherein the access request includes a communication service and a target identifier.

[0032] The ubiquitous network layer may refer to a layer composed of a variety of widely existing basic networks. For example, the ubiquitous network layer may include optical transmission networks, data communication networks, narrowband Internet of Things, operator public networks, satellite communications, wireless local area networks, wireless communication private networks, and clock synchronization networks. Thus, seamless information transmission and extensive connectivity can be achieved through the ubiquitous network layer.

[0033] The calling terminal may refer to an intelligent terminal that initiates an access request. Generally, intelligent terminals can be divided into dedicated terminals and soft terminals. Dedicated terminals may include multimedia dedicated dispatch terminals, intelligent desktop terminals, Session Initial Protocol (SIP) phones, cameras, drones and other audio and video terminals. Soft dispatch terminals may include operating system-based terminals and terminals that support Internet dispatch.

[0034] Among them, the access request may refer to a request initiated by the calling terminal for dispatching communication. Generally, the access request may include a communication service and a target identifier. The communication service may refer to the implementation service of dispatching communication in various business scenarios. Exemplarily, the business scenarios may include train dispatching communication, station dispatching communication, power supply dispatching communication, driving dispatching communication, ticket dispatching communication, passenger service communication, passenger station management communication, maintenance and repair operations, security communication and emergency communication, etc. The communication service may include: video conferencing service, telephone service, cluster intercom service, etc. The target identifier may refer to the identifier for establishing a communication connection between the calling terminal and the called terminal. Exemplarily, it may be a direct identifier of the called terminal, or it may be an indirect identifier for establishing an association relationship with the called terminal. Specifically, if the communication service is a video conferencing service, the target identifier may be a conference number; if the communication service is a telephone service, the target identifier may be a number corresponding to the called terminal. Among them, the called terminal may refer to an intelligent terminal that receives the access request initiated by the calling terminal.

[0035] It is worth noting that the calling terminal and the called terminal in the embodiment of the present invention can be intelligent terminals in any scene of a station, a vehicle depot, and a parking lot. In addition, the number of called terminals that establish communication services with the calling terminal is not limited.

[0036] S120. Parse the access request through the access layer, convert the access request into a standard data packet, and transmit the standard data packet to the core layer.

[0037] Among them, the access layer can refer to the layer that parses and processes the access request according to the protocol type of the access request. Exemplarily, the access layer can include an emergency access module, a video access module, and a gateway access module; the gateway access module can include a fiber access system (FAS) gateway access, a mission critical service (MCX) gateway access, a session initiation protocol (SIP) gateway access, a digital trunk access, and a user access gateway access, etc., to achieve access to analog walkie-talkies, mobile communications, and wireless train modulation.

[0038] The parsing may refer to analyzing and processing the protocol format of the access request to obtain corresponding data according to the protocol format corresponding to the access request. The standard data packet may refer to a data packet composed of access request information having a standard data format.

[0039] In an optional embodiment, the access request is parsed through the access layer and converted into a standard data packet, including: the access request is parsed through the access layer according to the protocol type of the access request, and the parsed result is converted into a standard data packet according to the standard protocol type.

[0040] The standard protocol type may refer to a standard data format corresponding to an access request. Generally, the standard protocol type corresponding to the access request may be matched according to the protocol format corresponding to the access request. Exemplarily, if the protocol format corresponding to the access request is FAS gateway access, the standard protocol type corresponding to the access request may be set as the data format set by the gateway access module.

[0041] Specifically, the access layer parses the data carried in the access request according to the protocol format corresponding to the access request, matches the standard protocol type corresponding to the access request according to the protocol format corresponding to the access request, and reconverts the parsing result according to the standard protocol type to generate a standard data packet. In this way, the transmission of the data packet is separated from the specific protocol format, and the separation of control and bearer is achieved, making the network architecture more open and flexible, and facilitating the expansion of subsequent services.

[0042] S130, receiving the standard data packet through the core layer and establishing a communication connection between the calling terminal and the called terminal corresponding to the target identifier according to the target identifier in the standard data packet, and sending a communication connection event to the service application layer.

[0043] The core layer refers to the layer for communication connection and implementation of specific communication services. Generally, the core layer can integrate communication capabilities based on the communication capabilities of the access layer, integrate the communication capabilities based on the access layer, and build a communication capability resource pool. Furthermore, with the communication capability resource pool as support, the standard communication capability call interface is encapsulated, and the call level is encapsulated with reference to the communication capability's own attributes, and the upper-layer business applications are supported in a service manner.

[0044] In an optional implementation, transmitting the standard data packet to the core layer through the access layer includes: transmitting the standard data packet to a communication scheduling module of the core layer through the access layer.

[0045] Among them, the communication scheduling module can refer to a module that realizes the communication interaction service between the calling terminal and the called terminal. Generally, it can be designed based on the relevant standards of the scheduling communication system and the next generation railway dedicated communication system (Next Generation Railway Communication System, LTE-R). Exemplarily, the communication scheduling module can realize the following functions: providing point-to-point audio and audio and video media communication functions; providing scheduling services such as multi-priority voice calls, ringing groups, continuous selection groups, forced insertion, forced removal, night service and emergency extensions; providing voice conference services such as joining, leaving, muting and speech control; providing grouping or ungrouping, voice intercom and speech control and other trunk intercom services; providing multi-priority video calls, ringing groups, continuous selection groups, forced insertion, forced removal, night service and emergency extensions; providing video conference services such as joining, leaving, muting, speech control, video control, desktop sharing and video distribution; providing SIP trunk interconnection services.

[0046] Specifically, after the access layer transmits the standard data packet to the communication scheduling module of the core layer, the communication scheduling module establishes a communication connection between the calling terminal and the called terminal according to the target identifier in the standard data packet. For example, if the calling terminal of the station initiates an access request for a video conference to the parking lot, the access request contains the Internet Protocol (IP) address and conference number of the visited parking lot, when the access request is transmitted to the access layer through the ubiquitous network layer, the access layer parses the access request, converts the access request into a standard data packet, and transmits the standard data packet to the communication scheduling module of the core layer, then the communication scheduling module determines the intelligent terminal consistent with the IP address of the visited parking lot in the standard data packet as the called terminal, and establishes a communication connection between the calling terminal and the called terminal through the conference number. Thus, when the station, depot or parking lot accesses the communication scheduling module through the transmission system network interface, a multimedia wired dispatching communication network is formed; when various wireless terminals access the communication scheduling module through the access layer, a multimedia wireless dispatching communication network is formed, the wired dispatching and wireless dispatching can be integrated, so that multiple services can communicate horizontally, realizing the unified architecture, unified deployment and unified resource allocation of the dispatching communication service, and reducing the waste of resource costs.

[0047] In an optional implementation, sending a communication connection event to a service application layer through a core layer includes: when a communication connection is established between a calling terminal and a called terminal corresponding to a target identifier, sending a communication connection event to a service application layer through a core layer; wherein the communication connection event includes a communication service. The communication connection event may refer to an event generated when a communication connection is established between a calling terminal and a called terminal corresponding to a target identifier.

[0048] Specifically, when the communication scheduling module establishes a communication connection between the calling terminal and the called terminal, and a communication connection is established between the calling terminal and the called terminal corresponding to the target identifier, a communication connection event indicating a successful communication connection can be generated, and the communication connection event can be sent to the business application layer, thereby providing an effective basis for subsequent business application layer operations.

[0049] S140: Receive a communication connection event through the service application layer, and implement a target communication service between the calling terminal and the called terminal corresponding to the target identifier according to a target standard calling mechanism matching the communication connection event.

[0050] Among them, the target standard calling mechanism may refer to a core layer calling mechanism that matches the communication service initiated by the calling terminal. Generally, the target standard calling mechanism may provide a standard calling mechanism according to the type of communication service. It is worth noting that the target standard calling mechanism may be established in advance according to the type of communication service. The target standard calling mechanism may include a communication capability calling mechanism and a business scenario calling mechanism to provide communication guarantee for application systems or intelligent application platforms at all levels.

[0051] The target communication service may refer to the communication service finally determined according to the target standard calling mechanism, which may generally include dispatch communication service, emergency command service, Geographic Information System (GIS) map service, video monitoring service, material management service, equipment monitoring service and office telephone service.

[0052] In an optional embodiment, a communication connection event is received through a service application layer, and a target communication service between a calling terminal and a called terminal corresponding to a target identifier is implemented based on a target standard calling mechanism that matches the communication connection event, including: obtaining a target standard calling mechanism that matches the communication connection event through a service application layer, and calling relevant modules of a core layer based on the target standard calling mechanism to implement a target communication service between a calling terminal and a called terminal corresponding to a target identifier.

[0053] The core layer related modules may refer to modules in the core layer that perform specific communication services, and may include, for example, an integrated switching module, a media processing module, a recording and recording module, a network management module, and a security management module.

[0054] Among them, the integrated switching module can specifically provide the following functions: provide terminal user registration and call authentication, call session control, service routing, user status subscription, call record query, inter-domain interconnection and software guardianship, etc.; provide basic scheduling services such as single call, group call, conference and forced insertion and removal; complete the storage, query and management, selection and routing of contracted user data; provide service registration, domain name resolution and load balancing functions; provide system address book management and distribution; provide terminal version, monitoring alarm notification message push; provide system service deployment management and service process guardianship; provide business system database storage, query, synchronization, optimization, management, monitoring and other functions, provide business transparent data file access and other functions.

[0055] Among them, the media processing module can specifically provide the following functions: provide media stream playback, media stream forwarding, transcoding, multi-channel voice mixing, video multi-screen processing and synthesis and other functions; realize media resource control, provide external business interfaces to provide conference creation, endpoint creation and topology connection and other operations; support the configuration of multiple media processing units, and the integrated switching unit performs business distribution, and supports load sharing between units.

[0056] The recording and video recording module can provide the following functions: recording, storage, management and listening of audio media resources; recording, storage, management and listening of audio and video media resources; recording, storage, management and viewing of video access systems; storage and review control functions, providing external service interfaces for recording and review, etc., and supporting clustered deployment and load sharing as a resource in the system;

[0057] Among them, the network management module can usually adopt the browser / server (B / S) architecture, which is composed of the network management server and the network management terminal, and provides configuration, control and status management, alarm management and log download of each business service unit. It can realize maintenance management functions such as configuration, alarm, performance, status, statistics, etc.

[0058] Among them, the security control module can be constructed according to the security protection level based on the security management center, network security boundary, secure communication network and secure computing environment, and implement the level protection work. Usually, the level that meets the basic security protection is the third level. The security control module can include a new generation of firewalls, antivirus servers, security audit servers and log audit servers. It is worth noting that the new generation of firewalls can include an intrusion prevention system (IPS), which has functions such as firewall, antivirus, intrusion prevention, application protection and threat intelligence, and can effectively resist network attacks from the Internet side; in addition, vulnerability scanning can regularly scan the operating systems of terminals, servers and network devices for vulnerabilities, discover system vulnerabilities in time, and provide references for managers to patch vulnerabilities to avoid external resources from launching attacks through system vulnerabilities. The security audit server can monitor and audit the behavior of each front-end, terminal and host device by modeling and analyzing features such as IP, media access control (MAC), port, protocol and traffic, and can also isolate devices that perform unconventional operations. The log audit server can realize centralized recording and auditing of servers, terminals, network security devices and network device logs.

[0059] Specifically, after receiving the communication connection event, the service application layer can obtain the target standard calling mechanism matching the communication service according to the communication service included in the communication connection event, and then call the integrated switching module, media processing module, recording and video recording module, network management module and security management module of the core layer according to the target standard calling mechanism, and realize the target communication service between the calling terminal and the called terminal by integrating the relevant modules of the core layer. Exemplarily, if the communication service included in the communication connection event is video conferencing, and the target standard calling mechanism matching the video conferencing is to record and process the conference content, the integrated switching module, media processing module and recording and video recording module of the core layer can be integrated and called. Therefore, by integrating the relevant modules of the core layer to realize the target communication service, the service can be separated from the control, breaking the boundary between the existing information technology (IT) and communication technology (CT), integrating the traditional business scenarios and the new information and communication technology (ICT), and realizing the integration of multiple communication methods in the voice domain and the IP domain.

[0060] The technical solution of the embodiment of the present invention is to transmit the access request initiated by the calling terminal to the access layer through the ubiquitous network layer; parse the access request through the access layer, convert the access request into a standard data packet, and transmit the standard data packet to the core layer; receive the standard data packet through the core layer and establish a communication connection between the calling terminal and the called terminal corresponding to the target identifier based on the target identifier in the standard data packet, and send a communication connection event to the business application layer; receive the communication connection event through the business application layer, and implement the target communication service between the calling terminal and the called terminal corresponding to the target identifier based on the target standard calling mechanism matching the communication connection event, thereby solving the problem that the line dispatching service and the non-line dispatching service cannot be fully integrated, and can fully integrate the line dispatching service and the non-line dispatching service to meet the scheduling communication needs of various business scenarios.
