Embodiments for Carrying Out the Present Invention The following is a further detailed description of the implementation of the technical solution in conjunction with the accompanying drawings, and the accompanying drawings show a system based on a mobile intelligent network—PHS (Personal Handyphone System) intelligent network, and the following description is made in conjunction with the PHS network. In the present invention, the concept of PA (Position Area) is defined, and a position area is composed of some base station coverage areas, and a PA designates a geographic area since the geographic location of the base station is fixed. Furthermore, when a user is using the PHS telephone, the PHS telephone certainly will make a call or receive a call through a base station, so the user and the base station are in the same area, if the base station is designated to belong to a PA, then it can be confirmed that the user is in the PA. The present invention designs that each PA is planned by the service provider, so as to achieve the purpose of distinguishing the call authorities. The PA is in logic sense, which can be illustrated by a numeric string of fixed length, such as 0250528700001234. The system of the present invention adopts the manner of intelligent network device, as illustrated in figure 1, which is mainly composed of the following parts: a service switching point device 20 (Service Switching point, SSP), a service control point device 10 (Service Control Point, SCP), and the wireless-side devices of the PHS intelligent network such as a base station device 40 and a base station control device 30. In the present invention, the 4 SSP device has the function of managing PA, and the management of PAs just needs operations on the SSP, and the SSP can use the CAP protocol in the No. 7 signaling to trigger the intelligent network service, when triggering the service, it transmits the present PA parameter of a user 50 (PHS telephone) to the service loaded on the SCP. Besides planning PA, the service logic software as described in the present invention will be loaded on the SCP, and numbers will be distributed, position areas will be configured, and home departments (groups) will be assigned for the service users (PHS telephone). After completing the configuration of the service data, when a service user makes a call or other users call the service user, the service logic will control whether the service user can connect the call according to the preset parameters. The present invention demands that the configuration of the service data be completed in the SSP and the radio network device firstly. These configurations of data comprise: (1) planning the base station coverage area of a specific department (group), so that t he geographic area of the specific department (group) is just covered by some base stations; defining the PA areas in the SSP, and these PAs cover the areas which need to redistribute the call authority, i.e., composed of the base stations which cover the geographic area, and setting these areas as the "service use-barred area" in the SSP, i.e., the restricted position area, then when a common user enters into these areas, the common user can not make/answer calls or receive/send short messages. (2) As for the telephone of a user of the specific department (group), setting in the SSP that the service (i.e., when these users enter into the area defined in step 1, they can make or answer calls) can be used in the "service use-barred area" and subscribing an intelligent network service (these users are referred to as service user in the present i nvention) for these users. The service logic software as described in the present invention needs to be loaded on the SCP, and the number of the service user (PHS telephone), the home department (group) of the service user, and the restricted position area (PA) of the service user need to be stored in the service system of the SCP. The service in the present invention has the characters as follows: the service divides several PAs into a restricted position area by using the aforesaid PA. When a non-service user enters into this area, the non-service user can not answer/make calls under the control of the SSP; when the present service user makes or answers calls in this area, only the call with the user of the same department (group) is permitted by the service. The PA data is transmitted to the service through the IDP (Initial Detection Point) parameter at the beginning of the call, and the service provides the function of setting the corresponding relationship between the PA and the restricted position area. The following is the explanation of the call flow which adopts the method of the present invention in conjunction with figure 2 to figure 6: Figure 6 is a schematic view of call flow according to the present invention, which explains the method for processing the call of a service user by the present invention: step 601, a user dialing numbers and making a call (the service user serves as a calling user or a called user), triggering the present service in the SCP through subscription data in 5 the SSP; step 602, the system obtaining the calling number, called number and the PA parameter from the service triggering data; step 603, the system matching the restricted area according to the PA parameter and determining whether the service user is in the restricted area, if the present location of the service user is not in the restricted area, then turn to step 606 and all are over; or else, turn to the next step 604; step 604, obtaining the calling number and the called number from the service triggering data; step 605, the system judging whether the calling number and the called number are the users of the same department, if they are, then turning to the next step and all are over; or else, turn to step 607; step 606, connecting the call, the calling user and the called user talk with each other; step 607, playing announcement to the calling user, and warning the user that call cannot be connected; and step 608, the system releasing the call, then the calls is over. The above call flow just explains the call processing flow of the service user, for the non-service user, its call authority is determined by the service switching point, and the call processing flow is similar to above mentioned, and it will not be described again. As illustrated in figure 2, in conjunction with figure 6, the explanation of the service user as a calling user in the non-restricted position area is as follows: 1. a service user dialing numbers and making a call, and triggering the present service of the SCP through the subscription data in the SSP. 2. the system obtaining the calling number, the called number and PA parameter f rom the service triggering data. 3. the system matching the restricted area according to the PA parameter, determining that the user is not in the restricted area, connecting the call, the calling user and the called user talking with each other, and then the call is over. As illustrated in figure 3, in conjunction with figure 6, the following is the explanation of the circumstance that a service user, as the calling user, dials the telephone of a user of the present department in the restricted position area: 1. a service user dialing numbers and making a call, and triggering the present service of the SCP through the subscription data in the SSP. 2. the system obtaining the calling number, the called number and PA parameter from the service triggering data. 3. the system checking the service data according to the calling number and the called number, determining that the calling user and the called user are the users of the same department (group), connecting the call, the calling user and the called user talking with each other, and then the call is over. As illustrated in figure 4, in conjunction with figure 6, the following is the explanation of the circumstance that a service user, as the calling user, dials the telephone of a user who does not belong to the present unit in the restricted position area: 1. a service user dialing numbers and making a call, and triggering the present service of the SCP through the subscription data in the SSP. 6 2. the system obtaining the calling number, the called number and PA parameter from the service triggering data. 3. the system matching the restricted area according to the PA parameter, determining that the user is not in the restricted area, checking the service data, determining that the calling user and the called user are not users of the same department (group), releasing the call, and then the call is over. As illustrated in figure 5, the following is the explanation that the non-service user, as the calling user, makes a call in the restricted position area: 1. a non-service user dialing numbers and making a call, and starting the call processing flow in the SSP. 2. the SSP judging that the user is in the restricted position area and judging that the user is not the subscribed service user according to the user data stored in the present system. 3. the SSP releasing the call, and the call is over. From the above embodiments, it can be seen that the call authorities of different users is distinguished from each other through the method of setting the restricted area according to the present invention, no matter for a non-service user or a service user, and no matter being a calling user or a called user, the effect of decentralized authority restricting call can be achieved, as a result, the effect that different users have different call authorities in different areas can be achieved. In the GSM network and the CDMA network, there is also a network protocol similar to the above PHS, transmission of information such as the calling number, the called number and the position parameter is provided in the protocol, so the method proposed by the present invention fits these networks, too.
