Detailed Description

The present invention will be described in further detail with reference to the following detailed description and accompanying drawings.

The first embodiment is as follows:

referring to fig. 1, fig. 1 shows a method for implementing call restriction, which is an application method of railway feature service call restriction under the GCSE _ LTE architecture based on role addressing. For example, a service mode of determining whether to connect a call according to the position of a called party based on call restriction of the position is used, and a section management system is used for ensuring the safety and reliability of operation along a line because a train constantly moves and changes at the operation time in some special environments, such as railway dispatching communication. According to the traffic density of the line, the railway line is divided into a plurality of dispatching areas with certain lengths, and all stations in the section and all trains running in the section are instructed by the traffic dispatcher in the section. Once the train is out of jurisdiction, the call is restricted. For another example, in the operation of a train, a locomotive dispatcher is not allowed to call a station attendant alone, but the station attendant can call the locomotive dispatcher alone, and the station attendant is allowed to call a locomotive main driver but is not allowed to call a locomotive auxiliary driver, and the like. In the two call restriction services, the former judges whether the position of the called party is in the range governed by the calling party according to the position of the called party, and the latter verifies according to the role of the user so as to ensure the reliability of scheduling communication. In the application environment, calling and called users often have certain functional roles, operators provide a role-based addressing mode for improving the reliability of dispatching communication, namely an intelligent network provides a role number and user equipment number registration mode for the users, and after the users complete registration, the users can dial the number of the functional role played by the called users when calls are initiated. The intelligent network completes the filtering of the call according to the type of the call restriction and filters the passing users, the intelligent network completes the service logic according to the service type and informs the called party to be normally connected with the calling party, and the users which do not pass the filtering release the user service through the bearing network.

Referring to fig. 1, the method for restricting a call of the present embodiment includes:

s101, receiving a call restriction service management request sent by application service equipment, wherein the call restriction service management request is a request forwarded by the application service equipment and sent to the application service equipment by calling equipment;

s102, acquiring a registration field according to a service parameter carried in the call restriction service management request;

s103, determining the type of call restriction registered by the acquired registration field according to the corresponding relation between the preset registration field and the call restriction type; the call restriction types include role function based call restriction and location based call restriction;

s104, according to the call restriction algorithm corresponding to the type of the call restriction, the call restriction processing is carried out on the call restriction service, and the processing result is sent to the application service equipment.

IN this embodiment, S101-S104 may be implemented by an Intelligent Network (IN) system. The called device and the calling device may be any devices supporting the dedicated environment service, including but not limited to a mobile phone, a tablet, a smart band, and the like. The user platforms of the called device and the calling device can be various, such as ios/android/blackberry/windows and other systems.

Referring to fig. 2, fig. 2 shows an LTE-based GCSE architecture, which includes a user equipment (UE/FAS /) and an Application unit thereof, wherein the user equipment runs an Application unit (GCSE Application Client) installed on the device; and an Application service device and its Application unit (GCSE Application Server). The calling device IN this embodiment may be a user equipment and an application unit thereof, when the calling device needs to initiate a call to a called device, the call between the calling device and the called device may be determined to be unable to be connected after being restricted, and for the call initiated by the calling user, the intelligent network IN needs to perform call restriction processing to obtain a result of whether connection with the called device is allowed, and the application service device IN this embodiment may forward a call restriction service management request initiated by the calling device and the application unit thereof to the intelligent network IN a GCSE network architecture based on LTE, and after the intelligent network IN completes a call restriction service, send the processing result to the calling device. In this embodiment, the application service device may be a server.

Further, the sending and receiving of the message of the transmission service may be implemented by a Session Initiation Protocol (SIP) Protocol between the calling device and the application service device.

Further, in this embodiment, corresponding application units may be installed on the calling device and the application service device, the application unit of the calling device may be used to initiate or accept a call service based on role addressing, and the application unit may enable an application program supporting a multi-user platform (ios/android/blackberry/windows /). The user equipment and the application unit have separability. The user equipment and the application unit thereof adopt a protocol SIP in the network to realize the message sending and receiving of the service. The application service device and its application unit also have a detachable feature.

Wherein the call restriction service management request received in S101 is forwarded by the application service device. After receiving the call restriction service management request sent by the calling equipment, the application service equipment forwards the call restriction service management request to the intelligent network system, and the intelligent network system completes the call restriction check and the call service logic of the call service between the calling party and the called party according to the service parameters carried by the call restriction service management request.

It is foreseen that the service parameters carried by the call restriction service management request necessarily include parameters for performing call restriction service management between the calling device (calling subscriber) and the called device (called subscriber).

Furthermore, in the role-based addressing mode, the intelligent network system provides a registration mode of a role number and a user equipment number for the user. The user equipment number may be a telephone number of the terminal, and the character number may be a field configured by any characters such as numbers, letters, symbols, and the like, which are set according to a certain rule. Therefore, for the calling device and the called device in this embodiment, both of them are provided with role numbers corresponding to device numbers, where the role numbers are numbers that can represent functional roles assumed by the corresponding user devices, such as roles of calling and called. In role-addressing based calls, the calling device often initiates a role call restriction service management request by dialing the role number of the called device. So in S101, the call restriction service management request may be a request initiated by the calling device by dialing the role number of the called device.

Further, the call restriction service management request carries service parameters related to the call restriction service between the calling device and the called device, where the service parameters include, but are not limited to, number information (at least one of a device number and a role number) of the calling device and the called device.

In this embodiment, the types of call restrictions implemented by the intelligent network system include, but are not limited to, role function based call restrictions and location based call restrictions; different devices (calling device or called device) may register at least one type of call restriction, IN this embodiment, the type of call restriction registered by the device may be indicated by a registration field corresponding to the calling device or the called device, and for facilitating the call restriction service processing of the intelligent network IN, the registration field may be directly or indirectly obtained from the service parameters. Such as the direct inclusion of a registration field in the service parameters.

Wherein, the step S104 of performing call restriction processing on the call restriction service according to the call restriction algorithm corresponding to the type of call restriction includes two cases:

the first method comprises the following steps: when the call restriction type registered in the registration field acquired in the step S102 is call restriction based on role function, acquiring function roles of the calling device and the called device and a calling user allowed call list and/or a called user allowed call list according to the service parameters;

and analyzing the call limit relationship between the calling equipment and the called equipment according to the function role and the calling user allowed call list and/or the called user allowed call list to obtain a call limit processing result.

The functional role can help the system to distinguish the roles of the calling and the called, namely, distinguish the roles of two devices to be connected related to the call restriction service management request. The call-defining relationship between the calling device and the called device includes whether the calling device is allowed to call the called device or whether the calling device is not allowed to call the called device. The calling user allowed call list and the called user allowed call list may include information (such as device numbers and/or role numbers) of objects that the calling device and the called device allow calls, respectively.

And the second method comprises the following steps: when the call restriction type registered in the registration field acquired in the step S102 is call restriction based on location, acquiring a jurisdiction area of a calling user of the calling device and acquiring a current location of the called device according to the service parameter;

if the current position is in the jurisdiction area of the calling user, the call restriction processing result is that the calling device is allowed to call the called device; otherwise, the calling device is not allowed to call the called device.

It can be understood that, when the processing result is sent to the application service device, if the processing result does not allow the calling device to call the called device, the processing result further includes a reason of the call failure and associated data, media data corresponding to the failure code, a detailed reason value, and the like, in order to enable the calling device to know the reason of the call failure. The intelligent network system can send the processing result to the called device through the SIP protocol. The processing result satisfies the SIP message format.

If the processing result is that the calling device is allowed to call the called device, the calling device and the called device perform a normal connection process through the Application service device and the GCSE Application client (fig. 2). When the call is allowed, if the service parameters carried IN the call restriction service management request do not include the device number of the calling device and/or the called device, the intelligent network IN needs to complete the translation from the role number of the calling device and the called device to the device number. And then, the call restriction processing result and the related parameters thereof pass through an SIP coding and decoding unit to complete the coding of the SIP message and respond to a service request sent by Application service equipment GCSE Application Server.

Further, in this embodiment, the service parameter includes, but is not limited to, at least one of a device number of the called device and a role number set corresponding to the device number, and at least one of a device number of the calling device and a role number set corresponding to the device number.

In an embodiment, the obtaining the functional roles of the calling device and the called device and the allowed call list of the calling user and/or the allowed call list of the called user according to the service parameters includes: acquiring the role number of calling equipment and the role number of called equipment according to the service parameters, and determining the functional role of the calling equipment and a calling user allowable call list according to the role number of the calling equipment; and determining the functional role of the called device and the allowed call list of the called user according to the role number of the called device.

In another embodiment, the obtaining of the jurisdiction of the calling party of the calling device and the current location of the called device according to the service parameters includes: acquiring a role number of calling equipment and an equipment number of called equipment according to the service parameters, and acquiring a calling party jurisdiction area of the calling equipment according to a preset corresponding relation between the role number of the calling equipment and the calling party jurisdiction area; and determining the current position of the called device according to the device number of the called device.

It can be understood that the device numbers of the calling device and the called device have a corresponding relationship with the role numbers, and when the service parameters do not have the role numbers of the calling device and/or the called device, the corresponding role numbers can be inquired in the intelligent network system according to the corresponding device numbers.

The scheme for determining the current position of the called device according to the device number of the called device comprises the following steps: the intelligent network sends position inquiry information to the called equipment, the information can be by means of paging standard information in protocol specification, and the called equipment reports the current position of the called equipment through EPC network (see figure 2); the EPC finally returns the position information to the intelligent network system; or, the intelligent network system sends a location query MESSAGE to the Application service device (GCSE Application service IN fig. 2), where the MESSAGE format may adopt an INVITE/REGISTER/INFO/MESSAGE/NOTIFY/401Unauthorized MESSAGE based on SIP, the Application service device forwards the location query MESSAGE to the calling device (GCSE Application IN fig. 2), the calling device obtains the cell location of the called device IN the LTE network, and sends a response to the Application service device, and the Application service device forwards the response to the intelligent network IN after receiving the response.

Further, in order to improve the security of the call service of the calling device and the called device, before S103, the method further includes determining the validity of the role numbers of the calling device and the called device. The judging process comprises the following steps: extracting (directly containing in the service parameter) from the service parameter or obtaining (only equipment number in the service parameter, obtaining role number according to the corresponding relation of the equipment number and the role number) the role numbers of the calling equipment and the called equipment according to the service parameter, and judging whether the role numbers of the calling equipment and the called equipment are legal or not. And if the information is legal, performing subsequent call restriction service processing, otherwise, returning information with illegal role numbers to the application service equipment.

Further, in order to simplify the call restriction service flow, in this embodiment, the registration field uses a segment of the role number. The fields in the role numbers of the calling device and the called device can be used as registration fields to set the call restriction types of the corresponding calling device or the corresponding called device. For example, location-based call restrictions are registered with a field in the role number of the calling device, or role-based call restrictions are registered with a field in the role number of the called device, and so on.

In this embodiment, acquiring the registration field according to the service parameter carried in the call restriction service management request includes:

acquiring the role number of calling equipment or the role number of called equipment according to the service parameters carried in the call restriction service management request; a registration field for registering call restriction in a character number of a calling device or a character number of a called device is extracted.

Furthermore, the call restriction types in this embodiment are multiple, and the same registration field can register multiple types of call restrictions, and in order to reasonably arrange the processing order of the call restriction services when the registration field registers multiple types of call restrictions, in this embodiment, different priorities are set for different types of call restrictions, and if it is determined that the registered call restrictions are multiple according to the registration field, the call restriction processing is performed on the multiple types of call restriction services registered in the registration field according to the priority order of the call restriction types. For example, determining that the registered call restriction is a role function-based call restriction and a location-based call restriction according to a registration field in a role number of a called device (or a calling device); and if the priority of the call restriction based on the role function is higher, the calling and called call restriction services are processed according to the role function. Then, the call restriction service processing based on the role function is carried out.

Further, in order to implement the above steps, it is essential to include data configuration of the call barring service in the intelligent network system. Before receiving a service establishment request sent by a called device, the method further comprises the following steps:

receiving data configuration of a call restriction service, wherein the configured data comprises a corresponding relation between an equipment number and a role number of each user, a jurisdiction area corresponding to the role number, each call restriction type, a priority corresponding to each call restriction type, a registration field of the role number for registering the call restriction service, a call restriction type registered in each registration field, a calling role and a calling relation of a called role;

and finishing corresponding configuration according to the data configuration.

Further, referring to fig. 3, the present embodiment further provides a call restriction method, which is applied to the application service device, and includes:

s301, the application service equipment receives a call restriction service management request sent by calling equipment;

s302, the application service equipment identifies the call restriction service management request and forwards the call restriction service management request to the intelligent network system; the call restriction service management request carries a registration field, and the registration field is used for determining the restriction type of the call restriction service;

and S303, the application service equipment receives a call restriction processing result fed back by the intelligent network system according to the call restriction service management request, and controls the calling equipment and the called equipment to carry out connection or informs the calling equipment to release the call according to the call restriction processing result.

Further, in this embodiment, before the calling device initiates a call to the called device, it needs to determine whether the call is allowed, where the determination is completed by an intelligent network, and the application service device performs data forwarding processing between the calling device and the intelligent network. The call restriction service management request may be initiated by the calling device through a role number of the called device, and after the initiation, the request is directly transmitted to the application service device. In order to reduce the workload of the intelligent network system, in S302, if the call restriction service management request identified by the application service device is initiated by the calling device according to the role number of the called device, the call restriction service management request is forwarded to the intelligent network system.

Further, in this embodiment, the call restriction processing result fed back by the intelligent network system according to the call restriction service management request includes allowing the calling device to call the called device and not allowing the calling device to call the called device. Under the condition of call permission, Application service equipment GCSE Application Clien establishes a normal continuing flow between calling equipment and called equipment; under the condition of call failure, the Application service equipment GCSE Application Client sends a message which contains a call failure message and conforms to a transmission protocol (such as SIP protocol) to the calling equipment, and the process is ended.

In order to facilitate the caller to know the details of the call failure, the application service device may further add the media data corresponding to the failure code sent by the intelligent network, the detailed cause value, and other information to the information fed back to the caller device.

By adopting the embodiment, the service range and the type of the call service limitation in the intelligent network system under the original GSM-R are expanded. And the intelligent network service flow realized by the seventh signaling is simplified. An efficient way of managing call restriction services is provided. By adopting the scheme, the call service limitation can be realized by the application units on the user equipment and the application service equipment, so that the extension of the call limitation service is easy, and only the application unit of the user equipment is required to be supported by extension. Compared with the existing call restriction service management mode, the embodiment registers different call restriction service types by using partial fields of the role numbers of the master device and the slave device, controls the sequence of service execution by using the service priority, and has simple service flow and easy expansion.

Example two:

referring to fig. 4, the present embodiment shows an intelligent network system including:

The call restriction service management request may be a request initiated to the application service device when the calling device calls the called device.

Further, the call restriction processing module 44 is configured to, when the registered call restriction type is call restriction based on a role function, obtain function roles of the calling device and the called device and a calling user allowed call list and/or a called user allowed call list according to the service parameters; analyzing a call limit relationship between calling equipment and called equipment according to the function role and the calling user allowed call list and/or the called user allowed call list to obtain a call limit processing result;

or, in another embodiment, the call restriction processing module 44 is configured to obtain the role number of the calling device and the device number of the called device according to the service parameter carried in the call restriction service management request, and obtain the jurisdiction of the calling device according to a preset correspondence between the role number of the calling device and the jurisdiction of the calling device; and determining the current position of the called equipment according to the equipment number of the called equipment.

Further, the obtaining module 42 is configured to obtain a role number of the calling device or a role number of the called device according to the service parameter carried in the call restriction service management request; a registration field for registering call restriction in a character number of a calling device or a character number of a called device is extracted.

Further, different types of call restrictions are set with different priorities, and if it is determined that there are multiple types of call restrictions registered according to the registration field, the call restriction processing module 44 is further configured to perform call restriction processing on the multiple types of call restrictions registered in the registration field according to the order of the priorities of the call restriction types.

Further, the intelligent network system of this embodiment further includes a configuration module 45, configured to receive data configuration of the call restriction service, where the configured data includes a correspondence between an equipment number of each user and a role number, a jurisdiction area corresponding to the role number, each call restriction type, a priority corresponding to each call restriction type, a registration field of the role number in which the call restriction service is registered, a type of call restriction registered in each registration field, a calling role, and a call relationship between the called role; and completing corresponding configuration according to the data configuration.

Referring to fig. 5, in this embodiment, a terminal device is further shown, which may be used as an application service device to cooperate with the intelligent network system to implement a call service restriction process between a calling device and a called device.

The terminal device includes a second receiving module 51, configured to receive a call restriction service management request sent by a calling device;

a processing module 52, configured to identify the call restriction service management request, and forward the call restriction service management request to the intelligent network system; the call restriction service management request carries a registration field, and the registration field is used for determining the restriction type of the call restriction service;

a third receiving module 53, configured to receive a call restriction processing result fed back by the intelligent network system according to the call restriction service management request, establish a connection between the calling device and the called device according to the call restriction processing result (when the calling device allows calling the called device), or notify the calling device to release the call (when the calling device does not allow calling the called device).

The intelligent network device of this embodiment may receive a call restriction service management request sent by an application service device, where the call restriction service management request is a request forwarded by the application service device and sent by a calling device to the application service device; acquiring a registration field according to a service parameter carried in the call restriction service management request; determining the type of call restriction registered by the registration field according to the corresponding relation between the preset registration field and the type of call restriction; the call restriction types include role function-based call restriction and location-based call restriction; and carrying out call restriction processing on the call service according to a call restriction algorithm corresponding to the type of the call restriction, and sending a processing result to the application service equipment. The intelligent network system realizes the expansion of the service range and the type of the call restriction of the intelligent network service under the original GSM-R, and simplifies the intelligent network service flow realized by the No. seven signaling. The present embodiment also provides an effective way of managing call restriction services. Compared with the existing call restriction service management mode, the method registers different call restriction service types by using partial fields of the calling and called role numbers, controls the sequence of service execution by using the service priority, and has simple service flow and easy expansion.

Example three:

The function of the first receiving module 41 in the second embodiment can be implemented by the intelligent network service management unit 631 in this embodiment.

And the role management unit 633 completes function processing based on role addressing, wherein in practical application, role addressing and call restriction functions have an association relationship. The unit completes the legality analysis of the role number format and provides a conversion operation interface between the role number and the equipment number.

The service restriction processing unit 630 of the Intelligent Network (IN) completes the configuration of the call restriction related parameters and the call restriction service processing. Specifically, it can be further divided into a call restriction service management unit 634, a call restriction data configuration unit 638, a call restriction algorithm unit 635, a user location query unit 637, and a service database 636. In the second embodiment, the obtaining module 42, the determining module 43 and the call restriction processing module 44 may be implemented by a service restriction processing unit of an intelligent network.

The call restriction service management unit 634, according to the parameters of the calling and called role numbers (if there is no role number, the device number is translated into the role number) carried in the call restriction service management request initiated by the application service device, extracts the registration field for registering call restriction in the role number, accesses the service database, and obtains the call restriction service list of service registration according to the registration field.

The following describes an exemplary operation manner of the call restriction data configuration in this embodiment with reference to fig. 7.

The method comprises the following steps: and the authorized user logs IN the intelligent network IN to configure the network management background and executes the data configuration operation of the call restriction service. The configured data includes: the corresponding relation between the user's role number and the device number, the jurisdiction area corresponding to the role number, the priority corresponding to the call restriction service type, the registration field for registering the call restriction service (the registration field is from a section of field of the user's role number), the service type of the registered call restriction service, the calling relation between the calling role and the called role, and the like. During service configuration, the form of an object model or a data table can be adopted. When sending data to the call limitation data configuration unit, a message conforming to the network protocol specification, such as SNMP protocol transmission, is sent.

The registration field of the role number may be several operation digits in the called role number carried when the calling user initiates a service request. The operation positions can embody the roles (calling roles or called roles) which can be assumed by the user, and the design of the role numbers is generally used as the basis.

And step two, the intelligent network IN call restriction data receiving unit receives the data configuration information from the intelligent network IN configuration network management background, stores the information into a user role number and equipment number corresponding relation table, a role number administration area table, a call restriction service description table (containing the description of the type and the priority of the call restriction service), a call restriction service subscription table (the registration field of the subscription call restriction service and the priority of the call restriction service), a calling role allowed call list and a called role allowed call list, and stores the information into a service database.

The service database can be a small database management system, which is responsible for the management and maintenance of the whole intelligent network software system and provides an operation interface for service software, and meanwhile, the background configures the data of the software to provide powerful support for the normal operation of the service.

Role-based call restriction is illustrated below in conjunction with fig. 8.

The method comprises the following steps: the user logs in the Application unit GCSE Application Client of the user equipment, executes the role addressing call service based on the call matrix, dials the role number of the called equipment and initiates the role addressing call service request. The method for executing the service needs to send a message meeting network protocol specifications to Application service equipment GCSE Application Server, the network protocol includes but is not limited to session initiation protocol SIP, the message type can adopt request message and response message type in the SIP protocol, the method for sending the message can adopt INVITE/100Trying/180Ring/200OK and the like, and the message carries the role number of a calling user, the equipment number of the calling user and the role number of a called user. In practice, the number carried by the message may vary according to actual situations, and the embodiment is not limited to this.

In practice, the role addressing call service request is initiated to the application service device, and the application service device needs to forward the request to the intelligent network so that the intelligent network can process the call restriction of the calling device, so the role call service request in this embodiment is actually the call restriction service management request in embodiment one and embodiment two.

Step two: the GCSE Application Server processes the role addressing service request based on the call matrix sent by the GCSE Application Client. The GCSE Application Server recognizes the number called by the GCSE Application Client as the role number format, and forwards the role addressing service request message to the intelligent network IN. The forwarded MESSAGE needs to conform to the network protocol SIP specification, the MESSAGE type is a request MESSAGE, and the method may be INVITE/REGISTER/INFO/MESSAGE/NOTIFY/401Unauthorized, and the like.

Step three: an Intelligent Network (IN) receives a role addressing service request message sent by a GCSE Application Server.

The role addressing service request message firstly passes through an intelligent network service management unit, the unit identifies the service type, and if the service is a call request type service, the call request type service needs to be processed by a call limitation service management unit. In the figure, an intelligent network service management unit and a call restriction service management unit are unified as a service management unit.

First, the call restriction service managing unit accesses the SIP codec unit. The SIP coding and decoding unit completes the analysis of the SIP message code stream according to the SIP message format definition between the application server and the application unit thereof and the intelligent network IN, and extracts the relevant parameters carried IN the role addressing service request from the SIP message code stream. Such as the character number of the calling or called party and the equipment number of the calling party.

Secondly, the call restriction service management unit extracts the role numbers of the calling party and the called party in the previous step, and the validity judgment of the role numbers is completed by accessing the role management unit; and extracting a call restriction service registration field of the called user role number, and analyzing a call restriction service list registered according to the registration field. The call restriction service management unit executes the process control and management of the call restriction service according to the call restriction service types and the corresponding priorities of the types in the service list, calls a call restriction algorithm, and returns the algorithm execution result to the intelligent network service management unit. When the service registration is only the call matrix service, firstly, the algorithm data preparation operation is executed, namely, the role database is accessed to obtain the functional roles of the current calling party and the current called party, and then the call matrix algorithm is executed.

The process of executing the call matrix algorithm includes: analyzing a calling party allowed call list or a called party allowed call list through an access interface provided by a service database, analyzing a call limiting relation between two roles (user equipment and called equipment), returning a call limiting result, namely allowing a call, a call failure, a failure reason and associated data, and acquiring media data and a detailed reason value corresponding to a failure code if the call limiting result is failed. And finally, forwarding the processing result and the related data thereof to an intelligent network service management unit.

And the intelligent network service management unit completes service processing according to the call restriction result and the GCSE Application server request service logic. If the call is allowed, the unit needs to complete the translation of the calling and called character numbers to the device number. And then, the call restriction result and the related parameters thereof pass through an SIP coding and decoding unit to complete the coding of the SIP message and respond to the service request sent by the GCSE Application Server.

Step five: the GCSE Application Server processes the call response according to the result of the call restriction, and if the call is allowed, the GCSE Application Server starts to establish a normal connection flow between the calling equipment and the called equipment according to the numbers of the calling equipment and the called equipment returned by the intelligent network; if the call fails, the related parameters such as the call failure reason value, the detailed reason and the like are forwarded to the GCSE Application Client of the calling user.

Step six: under the permission of calling, the calling and called users carry out normal continuing flow through GCSE Application client; and under the condition of call failure, the calling user receives a call failure message forwarded by the Application service equipment through the GCSE Application Client, and the process is ended.

Referring to fig. 9, fig. 9 shows a flowchart of a location-based call restriction algorithm, which is described below in conjunction with fig. 9 for illustrating location-based call restriction:

the method comprises the following steps: the user logs in the Application unit GCSE Application Client of the user equipment, executes the role addressing calling service based on the position calling limitation and dials the role number. The execution service needs to send a message meeting the network protocol specification to the Application service equipment GCSE Application Server, the network protocol can adopt a session initiation protocol SIP, the message type can adopt a request message and a response message type in the protocol, the method can adopt INVITE/100Trying/180Ring/200OK, and the message carries the role number of a calling user, the equipment number of the calling user, the role number of a called user/the equipment number of the called user (the number of the called user is the number dialed by the user, or one of the two numbers is selected).

Step two: the GCSE Application Server processes the role addressing service message of the call limitation based on the position sent by the GCSE Application Client. The GCSE Application Server recognizes the number of the service call as the role number format and forwards the message to the intelligent network IN. The MESSAGE needs to conform to the network protocol SIP specification, the MESSAGE type is a request MESSAGE, and the method can be INVITE/REGISTER/INFO/MESSAGE/NOTIFY/401 Unauuthorized and the like.

Step three: an Intelligent Network (IN) receives a role addressing call service message sent by a GCSE Application Server.

The message is first passed through the intelligent network service management unit to identify the service type, and if it is the call request service, the message is forwarded to the call restriction service management unit.

First, the call restriction service managing unit accesses the SIP codec unit. The SIP coding and decoding unit completes the analysis of the SIP message code stream according to the SIP message format definition between the application server and the application unit thereof and the intelligent network IN, and extracts the relevant parameters carried IN the call request.

Secondly, the call restriction service management unit extracts the role number of the called user in the previous step, extracts the role numbers of the calling user and the called user, accesses the role management unit and judges the legality of the role number; and extracting the key field of the role number of the called user, and analyzing the registered service type list of the call limitation. The call restriction service management unit executes service process management according to the service type and priority registered by the service type, calls a call restriction algorithm, and returns the algorithm execution result to the intelligent network service management unit. When the service registration is found to be the call restriction service based on the position, firstly, the algorithm data preparation operation is executed, when the called number is the role number, the operation interface of the service processing unit is required to be accessed, the role number of the called user is translated into the equipment number, then the role number of the calling user is extracted, and then the call restriction algorithm based on the position is executed.

Referring to fig. 9, the location-based call restriction algorithm flow includes: and accessing a data operation interface provided by a service database according to the role number of the calling user, and searching the jurisdiction list of the calling user.

And then, calling a query unit of the position of the called user to acquire the position of the called user.

The user position inquiry unit can inquire through two modes, 1) the user position inquiry unit accesses the EPC, the EPC network sends a position inquiry message to the called equipment, the message can be by means of a paging standard message in a protocol specification, and the called equipment reports the current position of the called equipment through the EPC network; the EPC finally returns the position information to the user position query unit; 2) the user position inquiry unit sends a position inquiry MESSAGE to the GCSE Application Server, the MESSAGE format adopts an SIP-based INVITE/REGISTER/INFO/MESSAGE/NOTIFY/401Unauthorized MESSAGE, the GCSE Application Server forwards the position inquiry MESSAGE to the GCSE Application (calling equipment), the GCSE Application acquires the cell position of the called equipment IN the LTE network, and responses the position information to the GCSE Application Server, and the GCSE Application Server forwards the position inquiry MESSAGE to the user position inquiry unit of the intelligent network IN after receiving the position inquiry MESSAGE.

And then, comparing the relation between the jurisdiction list of the calling user and the position of the called user through a database interface provided by a service database, and judging whether the position of the called user is in or out of the jurisdiction of the calling user. The comparison result is the determination result of the location-based call restriction. The position of the called user is in the jurisdiction of the calling user, and the calling is allowed, otherwise, the calling is failed. And after receiving the result, the call restriction service management unit acquires the associated data according to the result, for example, acquires the media data and the detailed reason value corresponding to the failure code under the failure condition. And finally, forwarding the processing result and the related data thereof to an intelligent network service management unit.

And the intelligent network service management unit completes service processing according to the call limitation result and the service type requested by the GCSE Application server. If the call is allowed, the unit needs to complete the translation of the calling and called character numbers to the device number. And then, the call restriction result and the related parameters thereof pass through an SIP coding and decoding unit to complete the coding of the SIP message and respond to the service request sent by the GCSE Application Server.

Step five: the GCSE Application Server processes the call response according to the result of the call restriction, and if the call is allowed, the GCSE Application Server starts to establish the normal continuing flow of the calling equipment and the called equipment according to the numbers of the calling equipment and the called equipment returned by the intelligent network; if the call fails, the related parameters such as the call failure reason value, the detailed reason and the like are forwarded to the GCSE Application Client.

Step six: under the permission of calling, the calling and called users carry out normal continuing flow through GCSE Application client; and under the condition of call failure, the calling user receives the call failure message through the GCSE Application Client, and the process is ended.

Next, how to perform call service restriction when there are a plurality of call restriction services registered in the registration field will be described. It is assumed that the call matrix has a higher priority than the location based call restriction service when the subscriber is registered.

The method comprises the following steps: the user logs in the Application unit GCSE Application Client of the user equipment, executes the role addressing calling service based on the position calling limitation and dials the role number. The execution service needs to send a message meeting the network protocol specification to the GCSE Application Server, the network protocol can adopt a Session Initiation Protocol (SIP), the message type can adopt a request message and a response message type in the protocol, the method can adopt INVITE/100Trying/180Ring/200OK, and the message carries the role number of a calling user, the equipment number of the calling user, the role number of a called user/the equipment number of the called user (the number of the called user is the number dialed by the user, and one of the two numbers is selected).

Secondly, the call restriction service management unit extracts the role number of the called user in the previous step, extracts the role numbers of the calling user and the called user, accesses the role management unit and judges the legality of the role number; and extracting the registration field of the role number of the called user, and analyzing the registered service type list of the call limitation. The call restriction service management unit executes service process management according to the call restriction service types and the priorities of the types, calls a call restriction algorithm, and returns the algorithm execution result to the intelligent network service management unit. When the discovery service registers two call restriction services, call matrix and location-based call restriction. The call restriction service management unit controls the execution sequence and process of the algorithm, the data preparation is executed firstly before the algorithm is executed, and the execution process of the algorithm is controlled according to the execution result of the previous algorithm. At this time, the priority of the configured call matrix is higher than the location-based call restriction. The call matrix algorithm is executed first.

Firstly, performing algorithm data preparation operation, extracting a field for displaying the role of the user in the role number, and then performing a call matrix algorithm.

The calling matrix algorithm obtains the registration fields of the role numbers of the current calling party and the current called party, analyzes the calling party allowed calling list or the called party allowed calling list through the service database access interface, analyzes the call limiting relationship between the two roles (the calling party and the called party), and returns the call limiting result, namely the allowed calling, the call failure and the failure reason. If the call is limited, the call limitation service management unit acquires the associated data according to the result after receiving the result, and acquires the media data and the detailed reason value corresponding to the failure code if the result is failed. And finally, forwarding the processing result and the related data thereof to an intelligent network service management unit. If the call is allowed, the location-based call restriction algorithm continues to be executed.

The calling limitation service based on the position starts to execute, firstly, the algorithm data preparation operation is executed, when the called number is the role number, the operation interface of the service processing unit is required to be accessed, the role number of the called user is translated into the equipment number, then the role number of the calling user is extracted, and then the calling limitation algorithm based on the position is executed.

The calling limitation algorithm based on the position firstly accesses a data operation interface provided by a service database according to the role number of a calling user and searches a list of the jurisdiction area of the calling user; secondly, calling a query unit of the position of the called user to acquire the current position of the called user;

the user position inquiry unit can inquire through two modes, 1) the user position inquiry unit accesses the EPC, the EPC network sends a position inquiry message to the called equipment, the message can be by means of a paging standard message in a protocol specification, and the called equipment reports the current position of the called equipment through the EPC network; the EPC finally returns the position information to the user position query unit; 2) the user position inquiry unit sends a position inquiry MESSAGE to the GCSE Application Server, the MESSAGE format adopts an SIP-based INVITE/REGISTER/INFO/MESSAGE/NOTIFY/401Unauthorized MESSAGE, the GCSE Application Server forwards the position inquiry MESSAGE to the GCSE Application, the GCSE Application acquires the cell position of the called equipment IN the LTE network, and responses the position information to the GCSE Application Server, and the GCSE Application Server forwards the position inquiry MESSAGE to a user position inquiry unit of the intelligent network IN after receiving the position inquiry MESSAGE.

Step five: the GCSE Application Server processes the call response according to the result of the call restriction, and if the call is allowed, the GCSE Application Server starts to establish a normal continuing flow according to the numbers of the calling equipment and the called equipment returned by the intelligent network; if the call fails, the related parameters such as the call failure reason value, the detailed reason and the like are forwarded to the GCSE Application Client.
