Description

FIELD OF THE INVENTION

The invention relates to an intelligent network service, in particular, to a method and system for requesting information about the location or status of a subscriber of a node in an intelligent network.

State of the art

In an intelligent network, switching and service are separate. Switches only carry out the basic functions of switching, and the entire control of intelligent services is performed at a different level of the network, i.e. in an intelligent network. An intelligent network mainly consists of a service control center (CSP), a service switching point (FSC), a service management system (COO), and a service creation environment (MTR). In an intelligent network, service control function modules (FCS) perform service logic control functions, and service switching function (FCT) modules perform switching functions. The FCF informs the FCO of the various events that occurred during the call. The call may be suspended, waiting for an additional command from the FCF.

FUO can use the applied protocol of mobile objects (PPO), signaling for communication with the home position register (DRP), the switching center in the network of communications with mobile objects (CSC), the node support radio packet data service (GPRS), etc. to expand its capabilities. Based on this, in some suitable specifications, such as 23.078 V4.0 and higher. The 3rd Generation Participation Project (3GPP) defines the way in which the FSF can request position information and the status of the subscriber assigned to the CSC via the DRP using the interrogation mechanism at any time (OLV) at the circuit level.

However, in the prior art for the FCF, it is not possible to request position information and subscriber status related to the serving GPRS support node (OUP) through the PDD at the packet level. Although GPRS position information can be requested through the center of the position of the moving objects during the internetwork transition (PSC), the status of the subscriber cannot be obtained. Therefore, some relevant services cannot be implemented, and the addition of suitable CPC devices is necessary. Since the OUP is a serving GPRS support node, in reality the requested GPRS information must be OUP information. They are identical in essence and the difference between them is that they are described from different points of view. These two methods of description, which in relation to each individually correspond to the functional essence and service, are used later in industrial use.

Since GPRS position information and subscriber status cannot be requested through the PDD in the prior art, services associated with this kind of information, for example, some services that need GPRS information, such as protocol context, cannot be provided to subscribers. Therefore, network capabilities are limited and network adaptability is reduced, since position information cannot be requested through the DRP.

SUMMARY OF THE INVENTION

To solve the above problems, the main objective of the invention is to provide a method and system for requesting information about the location or status of a subscriber node in an intelligent network. This method and system allows you to request information about the position and status of the subscriber related to GPRS, as a result of which the network capabilities can be expanded and network adaptability is increased.

To achieve this goal, the invention proposes a method of requesting information about the position or status of a subscriber node in an intelligent network. With this method, the FCF module can request information on the position and status of the subscriber related to GPRS through the DRP. The method includes the following steps.

but. First, the FCL module within the mobile facility network (gsm FFS) sends an ATI REQUEST message at any time (ATI REQUEST), which at least includes three parameters: gsm FSO address, Requested Info and the mobile station identification number. Among them, the requested information not only shows that the required information is either position information or the status of the subscriber, but also that the required information is assigned either to the CTC or to the PMO, and the identification number of the mobile station can be the international identification number of the mobile station ( MINPS) or mobile station identification number for a digital communications network with integrated services (INPSTSKU).

b. after receiving a request message from gsmFUO, the DRP sends a corresponding ATI ACK response message to gsmFUO corresponding to the requested information (Requested Info). In other words, if position information is requested, the response message includes position information; if the subscriber state is requested, the response message includes the subscriber state; if information related to the CTC is requested, the response message includes information related to the CTC; if information related to GPRS is requested, the response message includes information related to GPRS.

The invention also proposed a system for requesting information about the position and status of a subscriber node in an intelligent network. The system comprises: a device for sending a request message located in a gsm FUO, and a device for receiving a request message located in a DRP, respectively, for sending and receiving ATI REQUEST messages, which include at least three parameters: gsm FUO address, requested information (Requested Info) and mobile radio station identification number; as well as a device for sending a response message located in the DRP, and a device for receiving a response message located in gsm FUO. After there is a received request message from gsmFUO, the device for sending a response message to the DRP returns to gsmFUO the corresponding response message according to the requested information contained in the request message, and the device for receiving a response message in gsmFUO receives this response message.

PPO is used for communication between a device for sending a message and a device for receiving a message. The requested information shows not only that the requested information is either position information or the status of the subscriber, but also that the requested information relates to the CSC or the PMO. The identification number of the mobile radio station may be MINPS or INPSCU. The ATI ACK response message corresponds to the Requested Info, in other words, if the requested information is assigned to the CTC, then the response message is assigned to the CTC, if the requested information is referred to the PMO, the response message is referred to the PMO, regardless of the fact that the requested message represents location information or status of the subscriber.

Using the invention, the OLV request message is expanded and information related to the PMO is added to both the ATI REQUEST and ATI ACK messages, so that subscriber position and status information related to the PMO can be polled. Thus, network capabilities are expanded, and network adaptability is enhanced.

Detailed description

The invention will be described below in more detail with reference to the accompanying drawings and preferred embodiments thereof.

As shown in FIG. 1, provided that the network is a network of moving objects, the FCF represents the gsmFFS, and the PPO is used for interaction between the gsmFFS and the DRP.

Turning to FIG. 2, which shows a signaling interaction process, the method according to the invention includes the following steps:

1) first, gsmFUO sends a polling request message at any time (OLV) to the DRP;

2) after receiving a request message from gsmFUO, the DRP sends a corresponding response message to gsmFUO according to the requested information (Requested Info) in the request message.

Table 1 and table 2 respectively illustrate the ATI REQUEST message in the prior art and in the invention. Among them, “name of the information element” means the name of the parameter; the term “requested” indicates that the parameter is mandatory, if it is, “M” represents used, otherwise “C” represents used; the term “description” refers to a brief explanation. The definitions remain the same in Tables 3 and 4. Tables 1 and 2 show that the ATI REQUEST message includes at least three parameters: the sender address (gsm FUO address), the requested information (Requested Info) and the identification number of the mobile radio station . In Table 2, the requested information not only shows that the information is either position information or the status of the subscriber, but also that the information is assigned to the CSC or to the PMO. The identification number of the mobile radio station can be represented as MINPS or INPSCSU.
