With the continuous development of the high-speed railway technology in China, the transportation of the high-speed railway brings great convenience to the production and the life of people. Meanwhile, in order to ensure the safety of transportation, a new communication system is required for railways as an important vehicle. As a Mobile Communication System special for Railway departments, a Future Railway Mobile Communication System (FRMCS for short) can realize the interconnection of a Railway wired network and a public telephone network and has the capability of accessing other voice and data networks. The FRMCS uses a 3GPP standardized Push-To-Talk (MCPTT) system as a key feature To support a group call function such as a single call and a group call, and can support a function, which is called a Functional Alias function. MCPTT uses a fourth generation mobile communication LTE technology at a transport layer and will evolve to a 5G mobile communication system. Since the FRMCS is deployed only on some Railway lines at the initial stage of deployment, the FRMCS needs to be communicated with a Global System for Mobile Communication-hierarchy (GSM-R) in a Railway System used in the conventional Railway industry, and the GSM-R uses a second generation Mobile Communication GSM technology in a transmission layer.

step S104, the communication node maps the user information of the first network into the user information of a second network, and converts the function alternative name to be processed into a function number;

step S106, the communication node initiates a function number processing flow to the network equipment of the second network according to the user information in the second network by the function number;

step S108, the communication node sends a function alias processing response carrying the function number processing result to the first network.

Specifically, table 1 shows a conversion relationship between the user information of the first network and the user information of the second network. It should be noted that table 1 is only an exemplary illustration. It can be understood that, in practical use, the user can adjust the conversion relationship in table 1 according to practical needs. Will not be described in detail herein.

TABLE 1

Specifically, in the present embodiment, a function alternative name (also called Functional Alias) is used to indicate a mailbox address, such as (1234567@ china hierarchy. And the function number is a numerical value such as 10010,11210 or the like.

It should be noted that, in this embodiment, the first network includes a network system such as an MCPTT network that can support the above-described function. And the second network is a network system comprising only a supported function number, e.g. a GSM network.

And the network device of the first network described hereinafter includes: the MCPTT server, the user of the first network comprises: the MCPTT client. And the network device of the second network comprises: GSM-R system equipment.

Optionally, after the communication node maps the user information of the first network to the user information of the second network, and converts the to-be-processed function alias into a function number, the method further includes: the communication node stores the mapping relation between the user information of the first network and the user information of the second network and the conversion relation between the function alternative name to be processed and the function number.

It should be noted that the user information of the first network includes: and MC service identification. And the subscriber information of the second network includes: and the user identification of the GSM-R system.

Specifically, table 2 shows the conversion relationship between the function alias and the function number. It should be noted that table 2 is only an exemplary illustration. It can be understood that, in practical use, the user can adjust the conversion relationship in table 2 according to practical needs. Will not be described in detail herein.

TABLE 2

Function number	Function balance
		10010	Dispatcher@ChinaRailway.cn
11210	TrainDriver@ChinaRailway.cn
		12010	StationStaff@ChinaRailway.cn

For example, after acquiring the request message for activating the function alternative name statistaff @ china railway.cn, the correspondent node converts statistaff @ china railway.cn to 12010.

Optionally, after the function number initiates a function number processing procedure to the network device of the second network, the method further includes: and the communication node converts the processed function number into a processed function alternative name according to the conversion relation and generates a processing result of the processed function alternative name.

For example, if the communication node initiates a registration procedure of the function number 12010 with the network device of the second network, the communication node receives the function number 12010 after having registered. In order for the first network to understand, the communication node converts the function number 12010 into StationStaff @ china raiway. Meanwhile, the effective registration time of the function number, the effective activation time of the function name and the information of whether activation is successful or not can be correspondingly generated if registration is successful.

After the communication node initiates a process flow to a second network, the method comprises: the communication node configures at least one of the following contents in a functional alias processing response and sends the configured contents to the network device of the first network: the user information of the first network, the processed function alternative name and the processing result of the processed function alternative name.

Specifically, the communication node can save the mapping relationship and the conversion relationship locally during each process flow. For example in a database of the communication node. In this way, in the subsequent use process, if it is determined through query that the requested function alias is located in the stored conversion relationship and the user information of the first network is located in the mapping relationship, the communication node directly initiates a processing flow of the corresponding function number to the network device of the second network. The processing flow is quick and convenient, and the beneficial effects of saving time and resources and improving the operation efficiency are achieved in the process of processing a large number of functions.

Through the above description of the embodiments, those skilled in the art can clearly understand that the method according to the above embodiments can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware, but the former is a better implementation mode in many cases. Based on such understanding, the technical solutions of the present invention may be embodied in the form of a software product, which is stored in a storage medium (e.g., ROM/RAM, magnetic disk, optical disk) and includes instructions for enabling a terminal device (e.g., a mobile phone, a computer, a server, or a network device) to execute the method according to the embodiments of the present invention.

In this embodiment, a request method for different functions is provided, which has already been described and will not be described again. Fig. 2 is a flowchart of a method for requesting a function alias according to an embodiment of the present invention, where the flowchart includes the following steps, as shown in fig. 2:

step S202, the network device of the first network sends, to the communication node, a function alias processing request to be processed by the network device of the second network according to a preset condition, where the function alias processing request includes: the user information of the first network is called the function to be processed.

Specifically, for the first network, the initiator initiating the function alias processing request may be a user of the first network or a network device of the first network. For the user, an inquiry request may be sent by the user of the first network to the network device of the first network if he wants to inquire about the already registered function numbers and thus wants to confirm the already activated function alias. Of course, for example, if the network device of the first network wants to deactivate the currently activated function, it only needs to determine to send the deactivation request to the network device according to the pre-stored context information.

Optionally, the preset condition includes: the function alternative name to be processed carries a designated field; the function alternative names to be processed are positioned in a function alternative name list to be processed; the network equipment of the first network does not store the related information of the function alternative name to be processed; context information stored in a network device of the first network.

Specifically, the function alternative name to be processed carries a specified field; the two conditions that the pending function alias is in the pending function alias list are mainly applied in the activated and deactivated processing requests. The information related to the function alternative name not stored in the network device of the first network is used for inquiring the activated function alternative name. The context information stored in the network device of the first network may be applied in the network device requesting deactivation of the function.

In addition, other preset conditions, such as during preemption of the function alias, further include: the preempted function is called differently. In the alternative addressing of the calling and called functions, the preset conditions include: the corresponding function of the called user is called.

Optionally, the method further comprises: and the network equipment of the first network stores the function alias processing response.

In order to better understand the technical solutions described in the above embodiments, the following six scenarios are also provided for understanding.

In the following scenario, the user of the first network is denoted MCPTT Client. And the network device of the first network is identified with the MCPTT server. The communication node is identified by IWF-R and the network equipment of the second network is identified by GSM-R system.

Scene 1:

fig. 3 is a flow chart illustrating activation of a function alias according to an embodiment of the present invention. In this embodiment, the GSM-R system performs overall control by controlling registration and activation of the function alternative (function number), and the function alternative initiated by the MCPTT Client in the MCPTT system is mapped to the function number registration process in the GSM-R system in the IWF-R. As shown in fig. 3:

step 1: the MCPTT Client sends a Functional alias activation request message to an MCPTT server, wherein the Functional alias activation request message carries a service identifier (MC service ID) of an initiator and a function alias (Functional alias) which needs to be activated by the initiator.

Step 2: the MCPTT server determines a control function of the function alternative name according to the pre-stored configuration, for example, after judging whether the function alternative name carries a special field (@ Chinarway. cn) or according to a pre-configured function alternative name list, the MCPTT server sends a Functional alias activation request message to an IWF-R gateway after judging that the activation of the function alternative name is controlled by a GSM-R system, wherein the Functional alias activation request message carries a service identifier (MC service ID) of an initiator and the function alternative name (Functional alias) which needs to be activated by the initiator.

And step 3: after receiving the Functional alias activation request message, the IWF-R realizes the conversion from the Functional alias to the Functional number and the mapping from the MC service ID to the GSM-R system user identifier according to the preset rule, and stores the mapping relation table. Alternatively, the mapping is equivalent to a conversion according to certain rules.

And 4, step 4: and 3, initiating a Registration process Registration of the function number to the GSM-R system by the IWF-R by using the function number and the GSM-R system user identification obtained in the step 3, wherein the Registration process Registration can be specifically referred to a GSM-R system L interface protocol.

And 5: according to the result of the GSM-R system completing the function number registration process, the IWF-R sends a Functional alias activation response message to the MCPTT server, wherein the message carries the MC service ID of the initiator, the activation state information of the Functional alias, the effective duration information of the activated Functional alias, and the success or failure indication of the activated Functional alias. The MCPTT server saves the received information.

Step 6: the MCPTT server sends a Functional alias activation response message to the MCPTT Client, wherein the MC service ID of the initiator, the activation state information of the Functional alias, the effective duration information of the activated Functional alias, and the success or failure indication of the activation of the Functional alias are carried. The MCPTT Client saves the received information.

Scene 2:

FIG. 4 is a flowchart illustrating a query of activated features according to an embodiment of the present invention. In the implementation, the registration and activation of the function alias of the GSM-R system control function are used for overall control, and the MCPTT Client in the MCPTT system initiates the inquiry of the activation state of the function alias function number of a specific user. As shown in fig. 4, the method comprises the following steps:

step 1: the MCPTT Client sends a Functional alias information request message to the MCPTT server, wherein the Functional alias information request message carries a service identifier (MC service ID) of an initiator and an MC service ID of a target user with a function to be queried being called a function number activation state.

Step 2: the MCPTT server firstly inquires whether the MCPTT server stores the activation state information of the function alias function number of the MC service ID aiming at the target user, and if the MCPTT server is not stored locally, the MCPTT server forwards the function alias information request message to the IWF-R gateway.

And step 3: after receiving the Functional alias information request message, the IWF-R gateway replaces the MC service ID of the initiator with the user identifier of the GSM-R system in a mapping mode, and also replaces the MC service ID of the target user with the function to be inquired, namely the function number activation state, with the user identifier of the GSM-R system in a mapping mode.

And 4, step 4: and 3, using the GSM-R system user identification obtained in the step 3, and initiating a query process of the function number activation state to the GSM-R system by the IWF-R, wherein the specific reference can be made to the L interface protocol of the GSM-R system.

And 5: according to the query result of the GSM-R system on the activation state of the function number, if the activated function number of the target user is queried in the GSM-R system, the IWF-R converts the function number into a function alternative name according to a pre-configured rule, and locally stores the mapping relation between the function number and the function alternative name. The IWF-R sends a Functional alias information request response message to the MCPTT server, wherein the message carries a service identifier (MC service ID) of an initiator, an MC service ID of a target user in an inquired function alias function number activation state and an inquiry result of the function alias function number activation state, and the inquiry result comprises the activated function alias function number information of the user.

Step 6: the MCPTT server sends a Functional alias information request response message to the MCPTT Client, wherein the Functional alias information request response message carries a service identifier (MC service ID) of an initiator, an MC service ID of a target user in an inquired function alias function number activation state and an inquiry result of the function alias function number activation state. The MCPTT Client saves the received information.

In the implementation, the GSM-R system controls the registration and activation of the function alias to carry out overall control, and when a user does not need to continue using a function number of a specific function alias, a deactivation process of the function alias can be initiated through the client. As shown in fig. 5: the method comprises the following steps:

step 1: the MCPTT Client sends a Functional alias de-activation request message to the MCPTT server, wherein the Functional alias carries the service identifier (MC service ID) of the initiator and the Functional identifier (Functional alias) which needs to be deactivated by the initiator.

Step 2: after receiving the Functional alias de-activation request message, the MCPTT server judges that the activated state of the Functional alias carried in the message is controlled by the GSM-R system according to the context information stored in advance, and forwards the Functional alias de-activation request message to the IWFR gateway.

And step 3: after receiving the Functional alias deactivation request message, the IWFR realizes the conversion from the Functional alias to the Functional number and the mapping from the MC service ID to the GSM-R system user identifier according to the pre-stored context.

And 4, step 4: and 3, using the user identification of the GSM-R system obtained in the step 3, and initiating a function number deregistration process to the GSM-R system by the IWF-R, which can be specifically referred to an L interface protocol of the GSM-R system.

And 5: according to the result of the GSM-R system completing the function number de-registration process, the IWFR sends a Functional alias de-activation response message to the MCPTT server, wherein the message carries the MC service ID of the initiator, the deactivation state information of the Functional alias, and a success or failure indication for deactivating the Functional alias. The MCPTT server saves the received information.

Step 6: the MCPTT server sends a Functional alias de-activation response message to the MCPTT Client, wherein the Functional alias de-activation response message carries a service identifier (MC service ID) of an initiator, deactivation state information of the Functional alias, and success or failure indication of activating the Functional alias. The MCPTT Client saves the received information.

In this embodiment, the GSM-R system controls the registration and activation of the function alias, and the MCPTT server triggers a deactivation process of the function alias function number of a specific user according to a preconfigured policy (e.g., in case of a function alias timeout). The embodiment is used for deactivating the function which is activated by the MCPTT Client, namely the function number. As shown in fig. 6: the method comprises the following steps:

step 1: the MCPTT server judges that the activation of the function alias needing to be deactivated is controlled by a GSM-R system according to the context information stored in advance, and the MCPTT server sends a Functional alias de-activation request message to an IWF-R gateway, wherein the MCPTT server carries a service identifier (MC service ID) of an initiator, the MC service ID of a user needing to deactivate the function alias of the initiator, and the function alias.

Step 2: after receiving the Functional alias deactivation request message, the IWFR realizes the conversion from the Functional alias to the Functional number and the mapping from the MC service ID to the GSM-R system user identifier according to the pre-stored context.

And step 3: and 3, using the GSM-R system user identification obtained in the step 3, and initiating a function number deregistration process to the GSM-R system by the IWFR, which can be specifically referred to a GSM-R system L interface protocol.

The MCPTT Client saves the received information.

Scene 5:

FIG. 7 is a flow chart illustrating a functional alias addressing according to an embodiment of the present invention. In the implementation, the GSM-R system controls the registration and activation of the function alias to perform overall control, and in the process of calling based on the function number, the calling side carries the called function alias during calling, so that the called function alias needs to be converted into the service identifier of the user through the addressing function of the function alias function number. As shown in fig. 7, the method comprises the following steps:

step 1: the MCPTT Client initiates a calling process based on the function alternative name to the MCPTT server, and informs the MCPTT server of the MC service ID carrying the calling party, the function alternative name of the calling party and the function alternative name of the called party.

In this embodiment, a method for managing the function difference is provided, which has already been described and will not be described again. Fig. 11 is a flowchart of a method for managing a function alias according to an embodiment of the present invention, where the flowchart includes the following steps, as shown in fig. 11:

step S1102, a network device of a first network processes a to-be-processed function alias in a function alias processing request sent by a user from the first network according to function alias configuration information;

step S1104, the network device of the first network sends the processed function alias to the user of the first network and a node for performing communication;

step S1106, the communication node calls a network device of the second network to initiate a function number processing procedure according to the processed function.

Specifically, in the present embodiment, a function alternative name (also called Functional Alias) is used to indicate a mailbox address, such as (1234567@ china hierarchy. And function numbers are numerical values such as 10010,11210, etc.

Optionally, when the function alias processing request is used to request activation of the function alias, the communication node initiates a function number processing procedure to a network device of a second network according to the processed function alias, where the function number processing procedure includes: the communication node initiates a function number registration process to the network equipment of the second network according to the activated function name and acquires the registered function number; and the communication node determines and stores the conversion relation between the registered function number and the activated function alias.

Optionally, when the function alias processing request is used to request to deactivate the function alias, the communication node initiates a function number processing procedure to a network device of a second network according to the processed function alias, where the function number processing procedure includes: the communication node deletes the deactivated function alias from the stored activated function alias list; and the communication node initiates a function number logout flow corresponding to the deactivated function alias to the network equipment of the second network according to the conversion relation and deletes the conversion relation.

Optionally, the network device of the first network sends the processed related information of the function difference to a user of the first network and a node for performing communication, where the related information at least includes: the processed state information of the function alias, the effective duration of the processed function alias, and the user information of the first network.

In order to better understand the technical solutions described in the above embodiments, the following two scenarios are also provided for understanding.

In the following scenario, the user of the first network is denoted MCPTT Client. And the network device of the first network is identified with the MCPTT server. The communication node is identified by IWF-R () and the network devices of the second network are identified by GSM-R system.

Scene 1:

fig. 12 is a flow chart illustrating another alternative function activation according to an embodiment of the present invention. The MCPTT Server in this embodiment serves as a control function of the Functional alias, and notifies the IWFR of the activated Functional alias after the Functional alias is activated. If the Functional alias needs to be interworked with the GSMR system, the IWFR triggers the registration process of the corresponding Functional Number in the GSM-R system. As shown in fig. 12, the method comprises the following steps:

step 1: the MCPTT Client sends a Functional alias activation request message to the MCPTT server, wherein the Functional alias activation request message carries a service identifier (MC service ID) of an initiator and a function alias (Functional alias) which needs to be activated by the initiator.

Step 2: the MCPTT server determines to activate the function alternative name for the MCPTT Client according to the pre-stored function alternative name configuration, and the MCPTT server sends a Functional alias activation response message to the MCPTT Client, wherein the Functional alias activation response message carries the MC service ID of the initiator, the activation state information of the Functional alias and the effective duration information of the activated Functional alias. The MCPTT Client saves the received information.

And step 3: according to the pre-configuration information, if the activated function alternative name needs to be communicated with a GSM-R system, the MCPTT server sends a Functional alias activation notification message to an IWFR gateway, carries the activated function alternative name and activates the MC service ID of the function alternative name user.

And 4, step 4: the IWFR saves the activated Functional alias, and activates the MC service ID of the user, and the MCPTT server information that controls the activation of the Functional alias. The IWFR sends a Functional alias activation notification response message to the MCPTT server.

And 5: according to the pre-configuration information, if the activated function is called to need to be communicated with the GSM-R system, the IWFR triggers the registration process of the response function number in the GSM-R system.

Step 6: after the function number is successfully registered, the IWFR stores the mapping relation between the function alias and the function number. The mapping relation can be used for the intercommunication between the subsequent MCPTT system and the GSM-R system.

Scene 2:

fig. 13 is a schematic flow chart illustrating a further deactivation of the function distinction according to an embodiment of the present invention. In this embodiment, the MCPTT Server serves as a control function of the Functional alias, and after the Functional alias is deactivated, notifies the IWFR of the deactivated Functional alias. As shown in fig. 13:

step 1: the MCPTT Client sends a Functional alias deactivation request message to the MCPTT server, wherein the Functional alias deactivation request message carries a service identifier (MC service ID) of an initiator and a function alias (Functional alias) which needs to be activated by the initiator.

Step 2: MCPTT server decides to deactivate the function alias (Functional alias) for the user, and MCPTT server sends a Functional alias deactivation response message to MCPTT Client.

And step 3: according to the pre-configuration information, if the activated function alias needs to be communicated with a GSM-R system, the MCPTT server sends a Functional alias deactivation notification message to an IWFR gateway, carries the deactivated function alias, and deactivates the MC service ID of the function alias user.

And 4, step 4: and the IWFR judges whether the related information of the Functional alias is stored or not according to the list of the stored and activated Functional alias. And if the information is saved, removing the Functional alias from the activated Functional alias list, and sending a Functional alias deactivation notification response message to the MCPTT server, wherein the Functional alias deactivation notification response message carries the processing result information.

And 5: according to the pre-configuration information, if the activated function alternative name establishes the mapping relation with the function number in the GSM-R system, the IWFR triggers the de-registration process of the corresponding function number in the GSM-R system.

Step 6: and after the function number is successfully registered, the IWFR deletes the mapping relation between the function alias and the function number.
