In the embodiment of the invention, when the secondary intelligent network receives the function addressing request from the user terminal, the function number corresponding to the function addressing request is queried locally, and if the query is successful, the calling process is directly continued; if the inquiry fails, the function addressing request is forwarded to the primary intelligent network, and whether the calling process is continued is judged according to the function addressing response returned by the primary intelligent network. The preferred embodiment is as follows:
(1) The user terminal sending the function addressing request is a calling user terminal, the user terminal to which the function number corresponding to the function addressing request belongs is a called user terminal, when the secondary intelligent network receives the function addressing request, the calling user terminal is checked, and after the check is passed, the corresponding function number is resolved from the function addressing request; then, inquiring the user number of the called user terminal corresponding to the function number in the local intelligent network unit, and if the inquiry is successful, directly continuing the calling process; if the inquiry fails, the functional addressing request is forwarded to the primary intelligent network.
(2) The first-level intelligent network analyzes the corresponding function number from the function addressing request, inquires the user number corresponding to the called user terminal through the function number, and returns a function addressing response carrying the user number of the called user terminal if the inquiry is successful; if the analysis fails or the query fails, a functional addressing response carrying the failure reason is returned.
(3) After the secondary intelligent network receives the function addressing response, if the function addressing response carries the user number of the called user terminal, continuing the calling process; if the function addressing response carries the failure reason, the calling user terminal call failure is replied, and the failure reason is carried.

(1) When a separate function number keep-alive mechanism is used: after registering the function number, the user terminal periodically sends a function number keep-alive message to the secondary intelligent network, and the secondary intelligent network receives the function number keep-alive message and forwards the function number keep-alive message to the primary intelligent network; and when the second intelligent network and the first intelligent network do not receive the function number keep-alive message within the set first threshold time, deleting the corresponding relation between the user number of the user terminal and the function number of the user terminal. In this section, the case where both the secondary intelligent network and the primary intelligent network are received and not received is mainly considered.
(2) When using the login keep-alive mechanism of the user terminal: after the user terminal logs in the secondary intelligent network, periodically sending a registration keep-alive message to the secondary intelligent network to maintain the login state of the user terminal; if the second-level intelligent network does not receive the registration keep-alive message within the set second threshold time, the user terminal is set to be in an offline state; and then deleting the corresponding relation between the user number of the user terminal and the function number of the user terminal directly or after waiting for the set time by the secondary intelligent network, and sending a notification message to the primary intelligent network, wherein the primary intelligent network deletes the corresponding relation between the user number of the user terminal and the function number of the user terminal after receiving the notification message.
Furthermore, in the embodiment of the invention, the management and maintenance of the function number registration, the function number inquiry and the function number cancellation of the user terminal can be realized through the primary intelligent network and the secondary intelligent network, and the management and maintenance of the function number can be also performed when the user terminal roams.
1. The user terminal registers the function number to the first intelligent network through the second intelligent network.
(1) The second intelligent network receives the function number registration request of the user terminal, and checks, and forwards the function number registration request to the first intelligent network after the check is passed, wherein the function number registration request carries the function number required to be registered by the user terminal.
(2) The first-level intelligent network checks the function number registration request, if the check is passed, the corresponding relation between the user number of the user terminal and the corresponding function number is established in the shared intelligent network database, and a registration success response is replied to the second-level intelligent network; if the verification fails, generating a failure reason, and replying a registration failure response to the secondary intelligent network.
(3) If the second intelligent network receives the registration success response, the corresponding relation between the user number of the user terminal and the corresponding function number is established in the local intelligent network unit, and the registration success response of the terminal is replied to the user terminal; if the second intelligent network receives the registration failure response, the second intelligent network replies a terminal registration failure response to the user terminal and carries the failure reason.
2. The user terminal inquires the function number from the first intelligent network through the second intelligent network.
(1) The second intelligent network receives the function number inquiry request of the user terminal, performs verification, and forwards the function number inquiry request to the first intelligent network after the verification is passed.
(2) After receiving the function number inquiry request, the primary intelligent network inquires the function number corresponding to the user terminal in the shared intelligent network database; if the inquiry is successful, replying an inquiry success response and carrying all function numbers corresponding to the user terminal; if the inquiry fails, the inquiry failure response is replied, and the failure reason is carried.
(3) If the second intelligent network receives the inquiry success response, updating the corresponding relation between the user number and the function number of the user terminal according to the inquiry success response, and replying a terminal inquiry success response carrying all the function numbers corresponding to the user terminal; and if the secondary intelligent network receives the query failure response, the secondary intelligent network replies a terminal query failure response carrying the failure reason to the user terminal.
3. The user terminal logs out the function number to the primary intelligent network through the secondary intelligent network.
(1) The second intelligent network receives the function number cancellation request of the user terminal, checks the function number cancellation request, and forwards the function number inquiry request to the first intelligent network after the check is passed; the function number cancellation request carries the function number required to cancel by the user terminal.
(2) The first-level intelligent network checks the function number cancellation request, if the check is passed, the corresponding relation between the user number of the user terminal and the corresponding function number is deleted in the shared intelligent network database, and a cancellation success response is replied to the second-level intelligent network; if the verification fails, generating a failure reason, and replying a cancellation failure response to the secondary intelligent network.
(3) If the second intelligent network receives the cancellation success response, deleting the corresponding relation between the user number of the user terminal and the corresponding function number in the local intelligent network unit, and replying the cancellation success response to the user terminal; if the second intelligent network receives the cancellation failure response, the second intelligent network replies the cancellation failure response of the terminal to the user terminal and carries the failure reason.
4. And when roaming occurs, the user terminal manages and maintains the function number.
In the embodiment of the invention, when a user terminal performs cross-office roaming, after finishing the login of a roaming office MCX system, firstly, a function number inquiry is carried out to a primary intelligent network through a secondary intelligent network corresponding to the roaming office, so that the secondary intelligent network corresponding to the roaming office establishes a corresponding relation between a user number of the user terminal and the function number of the user terminal, wherein the roaming office MCX system refers to a railway office MCX system to which the secondary intelligent network corresponding to the roaming office belongs; then, the user terminal registers, inquires or cancels the function number to the first intelligent network through the second intelligent network corresponding to the roaming bureau; specific registration, query and deregistration schemes can be found in the foregoing description; the cross-office roaming refers to that a user terminal moves from a coverage area of a home office to a coverage area of a roaming office or from a certain roaming office to another roaming office, and the home office and the roaming office are two different railway offices.
In order to more clearly demonstrate the technical scheme provided by the invention, the method provided by the embodiment of the invention is described in detail in the following by using a specific embodiment.
1. The device introduction.
In the embodiment of the invention, the all-way shared intelligent network equipment is called a primary intelligent network, maintains and manages the function numbers of all users in all ways, and is used for serving all-way function addressing business. In the embodiment of the invention, the office intelligent network unit in each railway office MCX system is called a secondary intelligent network, and the function number of the local office user is maintained and managed to serve the function addressing business in the local office. The functional number hierarchical maintenance and management method provided by the embodiment of the invention is provided with decisions by the primary intelligent network, and the secondary intelligent network maintains the local functional number data according to the decision result of the primary intelligent network. In order to more intuitively embody devices in various services, the following description and the accompanying drawings directly describe a primary intelligent network as a full-path shared intelligent network device, and directly describe a secondary intelligent network as an MCX system (office intelligent network).
In the embodiment of the invention, the user terminal can be a mobile terminal and has a unique identification user number.
1. A hierarchical processing method for function addressing service.
Considering that most of the function addressing services are mainly used in the railway bureau, the invention provides a method for performing function addressing hierarchical processing, which can effectively reduce the participation degree of all-way shared intelligent network equipment, avoid the problem that the function addressing can not be realized when all-way shared intelligent network equipment fails, and simultaneously can improve the efficiency of the function addressing services.
Because the local intelligent network unit of each railway office MCX system maintains the function number information of the user terminal of the railway office, when the function addressing service is carried out, the local intelligent network unit can firstly analyze and inquire, and if the function addressing is not inquired, the function addressing is requested to the whole common intelligent network equipment.
As shown in fig. 2, a flow chart of hierarchical processing for function addressing service mainly includes:
(1) The calling user terminal initiates a function addressing request to the local office MCX system, namely, the called user is called through the called function number.
(2) After receiving the function addressing request, the local office MCX system checks whether the calling user is an intelligent user or not, and after the checking is passed, the called user number (the user number of the called user terminal) is analyzed: firstly, inquiring the called user number corresponding to the called function number from the local intelligent network unit, and if the inquiry is successful, directly continuing the calling process.
(3) If the inquiry of the local intelligent network unit fails, a functional addressing request is initiated to the all-channel shared intelligent network equipment.
(4) After the full-path functional intelligent network receives the functional addressing request, if the analysis of the called user succeeds, the corresponding called user number of the MCX system is returned; if the analysis of the called user fails, the corresponding failure reason is returned.
(5) The MCX system continues the calling process according to the response returned by the all-channel shared intelligent network equipment if the response is successful; if the calling user fails, a calling user failure response is replied, and the failure reason is carried.
2. A method for quickly maintaining function numbers.
If the user terminal fails or does not actively log off in time and does not use the function number, other user terminals cannot address the called user as a function to be called after using the function number, and the function number of the user terminal cannot be automatically deleted until the function number exceeds the period in the intelligent network. Therefore, the invention provides a method for quickly maintaining the function number, which can maintain the function number in time and avoid the function number from being occupied by invalidation for a long time.
In the embodiment of the invention, two modes for realizing the rapid maintenance of the function number are provided, namely: the function number is quickly maintained through an independent function number keep-alive mechanism, and the function number is quickly maintained through a user login keep-alive mechanism.
1. And the function number is rapidly maintained through an independent function number keep-alive mechanism.
The method realizes effective maintenance of the user and the function number thereof through the independent function number keep-alive message. As shown in fig. 3, a flowchart for implementing the rapid maintenance of the function number by using a separate function number keep-alive mechanism mainly includes:
(1) When the user terminal registers the function number, the user terminal needs to periodically send a function number keep-alive message to the MCX system, and the MCX system forwards the function number keep-alive message to the all-channel shared intelligent network equipment; the period of this stage is set to T g1 The specific values may be set by the user according to actual conditions or experience.
(2) The MCX system and the all-channel shared intelligent network equipment are used for setting a first threshold time T g2 After the function number keep-alive message is not received, deleting the user number of the user terminal (in the figure, the user is simply called as user) in the corresponding database) Correspondence with its function number. Here a first threshold time T g2 The specific value of (c) may be set by the user according to actual conditions or experience.
2. And the quick maintenance of the function number is realized through a login keep-alive mechanism of the user.
The method does not need a separate function number keep-alive message, but realizes the maintenance of the function number by using the login state keep-alive message of the user terminal in the MCX system. As shown in fig. 4, a flowchart for implementing the rapid maintenance of the function number by the login keep-alive mechanism of the user mainly includes:
(1) After the user terminal completes the login of the MCX system, it needs to periodically send a registration keep-alive message to the MCX system to maintain the login state of the user. If the MCX system exceeds the set second threshold time T m2 And if the registration keep-alive message of the user is not received, the user is directly put into an offline state. The period of this stage is set to T m1 The specific value can be set by the user according to the actual situation or experience, and the second threshold time T m2 The specific value of (c) may be set by the user according to actual conditions or experience.
(2) The MCX system immediately or after a set time T m3 Then deleting the corresponding relation between the user number of the user terminal and the function number of the user terminal in the local intelligent network unit, and sending a notification message to the all-channel shared intelligent network equipment; the set time T here m3 The specific value of (c) may be set by the user according to actual conditions or experience.
(3) After receiving the notification, the all-channel shared intelligent network device 5G-IN deletes the corresponding relation between the user number of the user terminal and the function number thereof.
3. And (5) carrying out hierarchical maintenance and management on the function numbers.
The description is divided into four parts here, namely: maintenance and management during function number registration, maintenance and management during function number inquiry, maintenance and management during function number cancellation, and maintenance and management of function numbers during cross-office roaming.
1. Maintenance and management at the time of function number registration.
As shown in fig. 5, a hierarchical maintenance and management flowchart for the function number registration process mainly includes:
(1) The user terminal initiates a function number registration request to the current office MCX system.
(2) After receiving the function number registration request, the current office MCX system performs correlation verification to judge whether the user is an intelligent user, whether the registered function number format is correct, and the like. If yes, the function number registration request is forwarded to the all-channel shared intelligent network equipment.
(3) After receiving the registration of the function number, the all-way shared intelligent network equipment checks the format, registration upper limit and other information of the function number. If the verification is passed, establishing a corresponding relation between the user number of the user terminal and the function number in a shared intelligent network database, and replying a registration success response; if the verification fails, a corresponding failure reason is generated, a registration failure response is replied, and the failure reason is carried.
(4) After receiving the registration response, the MCX system establishes a corresponding relation between the user number of the user terminal and the registered function number in the local intelligent network unit if the registration is successful, and replies a successful registration response of the terminal; if the registration fails, replying a registration failure response of the terminal and carrying a failure reason.
(5) The mobile terminal user receives the registration response, if the registration is successful, the corresponding function number is stored for the subsequent service use; if the registration fails, prompting the user of the corresponding failure reason.
2. Maintenance and management in function number inquiry.
As shown in fig. 6, a hierarchical maintenance and management flowchart for a function number query process mainly includes:
(1) The user terminal initiates a function number query request to the current office MCX system.
(2) After receiving the function number inquiry request, the current office MCX system checks whether the user terminal is an intelligent user. If yes, forwarding the function number query request to the all-channel shared intelligent network equipment.
(3) And after the all-channel shared intelligent network equipment receives the function number query request, querying a shared intelligent network database to obtain the function number corresponding to the user terminal. If the inquiry is successful, replying an inquiry success response and carrying all function numbers corresponding to the user terminal; if the inquiry fails, the inquiry failure response is replied, and the failure reason is carried.
(4) After receiving the inquiry response, the MCX system updates the corresponding relation between the user number of the user terminal and the function number thereof in the local intelligent network unit if the inquiry is successful, and replies the inquiry success response of the terminal; if the inquiry fails, the inquiry failure response of the terminal is replied, and the failure reason is carried.
(5) The mobile terminal user receives the inquiry response, if the inquiry response is the successful response of the terminal, all the inquired function numbers are stored for the subsequent service use; if the terminal inquires the failure response, prompting the user of the corresponding failure reason.
3. Maintenance and management when the function number is logged off.
As shown in fig. 7, a hierarchical maintenance and management flowchart for a function number cancellation process mainly includes:
(1) The user terminal initiates a function number logout request to the current office MCX system.
(2) After receiving the request of canceling the function number, the current office MCX system carries out relevant check to judge whether the user is an intelligent user, whether the format of the cancelled function number is correct, and the like. If the function number is in the correct format, the function number cancellation request is forwarded to the all-channel shared intelligent network equipment.
(3) After receiving the request for canceling the function number, the all-way shared intelligent network device checks the format of the function number, whether the function number is registered or not, and other information. If the verification is passed, deleting the corresponding relation between the user number and the function number of the user terminal in the shared intelligent network database, and replying a cancellation success response; if the verification fails, a corresponding failure reason is generated, and a cancellation failure response is replied, carrying the failure reason.
(4) After receiving the cancellation response, the MCX system deletes the corresponding relation between the user and the cancelled function number in the local intelligent network unit if the cancellation response is successful, and replies the successful registration response of the terminal; if the result is the cancellation failure response, the cancellation failure response of the terminal is replied, and the failure reason is carried.
(5) The mobile terminal user receives the cancellation response, if the cancellation response is the successful response of the terminal registration, the corresponding function number is deleted; if the terminal logs out the failure response, prompting the user of the corresponding failure reason.
4. Maintenance and management of function numbers during cross-office roaming.
When the user terminal user generates cross-office roaming, the corresponding relation between the user number and the function number of the user terminal needs to be established in the roaming office MCX system. As shown in fig. 8, a flow chart for hierarchical maintenance and management of function numbers in cross-office roaming mainly includes:
(1) The user terminal performs cross-office roaming and completes the login process of the MCX system in the roaming office.
(2) After finishing the login of the roaming bureau MCX system, the user terminal needs to initiate a function number query request to the roaming bureau MCX system. The specific mode refers to the maintenance and management part in the process of inquiring the function numbers.
