Description
Technical Field
The present application relates to the field of trunking communication technologies, and in particular, to a call restriction method and system.
Background
In large-scale railway business, dispatchers, station operators, assistant operators and the like all have their own jurisdiction, and in order to ensure the high efficiency and the safety of dispatching and commanding, the scope of function number calling initiated by a user is required to be limited within the jurisdiction, namely: location based call restriction.
For example, when a scheduling person in Beijing office calls a driver or a vehicle operator by using a function number, the scheduling person only can call the driver or the vehicle operator in the jurisdiction of the scheduling person, and when users such as the driver or the vehicle operator exceed the jurisdiction of the scheduling person, the scheduling person cannot call the drivers or the vehicle operator by using the function number. The information of the jurisdiction areas (i.e., the dispatching areas) such as the cell lists corresponding to the calling users such as the dispatcher, the station attendant, the assistant attendant and the like is determined according to the transportation management requirements, as shown in fig. 1.
The call restriction function based on the position is greatly applied to a global system for mobile communications for railways (GSM-R), and the dispatcher can be effectively prevented from sending instructions to wrong objects, so that the safe execution of the dispatching service of the subway is guaranteed. However, in the railway broadband mobile communication system (LTE-R), under the framework of an intelligent network Service Control Point (SCP) based, there is no perfect solution for location-based call restriction, and the lack of this function is urgently needed to be solved.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below by referring to the accompanying drawings and examples.
The main idea of the application is that: under LTE-R, the position server collects the position information of the terminal, when the calling party calls the called party by the function number, the intelligent network SCP inquires the position information of the called terminal from the position server, and judges whether the calling is limited by the position according to the planned administration range of the calling party and the position information of the called terminal.
Under LTE-R, reference may be made to section 10.9 of 3GPP protocol TS 23.280 for management of terminal location information, which is not described herein in detail. The present application mainly describes a solution for location-based call restriction under the framework of an intelligent network SCP, as shown in fig. 2, the relevant flow is described as follows:
1. the dispatcher dials the function number to call the locomotive driver, and the Fixed user Access Switching (FAS) system sends the call to the mission critical Server (MC Server) through the session initiation protocol Core network (SIP Core), namely: a SIP invite (SIP INVITE) message is sent to the MC Server, carrying a function number for addressing.
2. The MC Server judges that the service is a function number service, forwards the service To the SCP for processing through a gateway IP multimedia service switching function (IM-SSF), the SCP checks the legality of the called function number, and if the called function number is legal, the called function number is mapped into a key task Push-To-Talk user Identity (MCPTT user ID).
3. Because the calling user is a wire user dispatcher, the SCP uses the MCPTT user ID as an identifier to query the Location Server (Location Server) for the Location information of the called terminal, as shown in the figure, the SCP sends a MESSAGE to the Location Server, where the MESSAGE carries the MCPTT user ID corresponding to the called function number, and is used for performing the called Location query.
4. And the Location Server returns the query result to the SCP through a 200OK message.
5. SCP judges whether the calling is limited by position according to the position information of the called terminal and the administration line and station range planned by the calling user in advance. If the position is limited, SCP sends 200OK information to MC Server through IM-SSF, which carries Release operation, to Release call.
6. The MC Server sends 200OK message to FAS system, which carries Release operation to Release call.
Under the 3GPP MC protocol architecture, the call functions such as function number addressing are also implemented on the MC Server, and therefore, the IM-SSF/SCP in fig. 2 is indicated by a dashed box. When the IM-SSF/SCP does not exist, the related functions are moved to the MC Server for realization.
In the above scheme, the Location Server is deployed in multiple ways, and the Location Server can be deployed in a hierarchical manner according to the client requirement, for example, the Location Server of each road bureau is deployed, and then the Location Server of the upper level is deployed in a centralized manner. These differences in deployment do not affect the Location-based call restriction solution described above, but only differ in the Location Server where the SCP queries the Location of the terminal.
The technical solution of the present application is further described in detail by a specific example.
Step 1: the FAS user of the calling party initiates a point call service through the function number, and sends an Invite message to the MC Server, wherein the Invite message carries the MCPTT user ID of the calling party, the calling function number and the called function number.
Step 2: after receiving the service request of the function number, the MC Server sends a Message to the IM-SSF/SCP, wherein the Message carries the ID of the calling MCPTT user, the calling function number and the called function number. After the SCP carries out validity check, the called function number is mapped to the corresponding called MCPTT user ID.
And 3, step 3: because the calling party is a wire subscriber dispatcher, the SCP inquires the Location Server about the Location information of the terminal according to the ID of the called MCPTT subscriber. The Information Element (IE) carried in the message is shown in Table 1:
TABLE 1
Information Element | Status | Description |
MCPTT user ID | M |
The Location Server returns the query result to SCP, and the IE carried in the message is shown in Table 2:
TABLE 2
The service types can be expanded, such as:
for video service, the MCPTT user ID in the table can also be expanded to MCVideo user ID;
for short data services, the MCPTT user ID in the table may also be extended to the MCData user ID.
And 4, step 4: SCP compares the position information of the called terminal returned by Location Server with the jurisdiction range of the calling user, if limited by the position, SCP sends Release operation to MC Server through IM-SSF, and the call is released.
The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the scope of protection of the present application.
