Embodiment 1

[0071] in, figure 1 It is a schematic flow chart of a method for determining the physical location of a non-IP fixed terminal in the present invention; as figure 1 As shown, the method includes the following steps:

[0072] S101: The access gateway receives a request initiated by a non-IP fixed terminal mounted under the access gateway, where the request may be a pulse or other forms.

[0073] Since the non-IP fixed terminal is directly mounted under the gateway, the access gateway, as the access gateway closest to the non-IP fixed terminal, is closer to the position of the non-IP fixed terminal, so , the location of the non-IP fixed terminal may be estimated based on the IP address information of the access gateway, therefore, the method includes:

[0074] S102: The access gateway forms a request message to the network side device (IMS core network in this embodiment) according to the request, where the request message carries the IP address information of the access gatewa...

Embodiment 2

[0085] The above embodiments are described in more detail below in conjunction with specific embodiments, wherein, figure 2 It is a schematic flowchart of a method for determining the physical location of a non-IP fixed terminal according to an embodiment of the present invention;

[0086] Such as figure 2 As shown, in this embodiment, the method for determining a non-fixed IP terminal mainly includes the following steps:

[0087] S201: The IMS core network obtains the IP address of the access gateway and the corresponding physical location information;

[0088] S202: Store the IP address of the access gateway and the corresponding physical location information and its association relationship in a location correspondence table, wherein the correspondence table can be set in the network side device or placed in other third parties in the storage device.

[0089] S203: The non-IP fixed terminal initiates a request to the core network through the access gateway closest to t...

Embodiment 3

[0111] Wherein, in the above-mentioned embodiment, the physical location of the user terminal acquired by the core network device is an approximate estimated physical location, which is not the exact physical location of the non-IP fixed terminal, therefore, in order to obtain a more accurate physical location ,Such as Figure 5 shown, take the following steps:

[0112] S501: The core network device obtains the subscriber line port number of the non-IP fixed terminal under the access gateway, the physical location information of the terminal, the IP address of the access gateway, and the physical location information of the access gateway;

[0113] S502: Store the subscriber line port number of the non-IP fixed terminal, the terminal's physical location information, the access gateway's IP address, and the access gateway's physical location information in a physical location correspondence table.

[0114] S503: The core network receives a call request message;

[0115] Where...

Abstract

The invention discloses a method for determining the position of a non-IP fixed terminal, and the method comprises steps of: A) receiving a request from the non-IP fixed terminal mounted on the gateway via an access gateway, and forming a request message which carries an IP address of the access gateway according to the request; B) transmitting the request message to network side equipment which determines the physical position of the non-IP fixed terminal according to the request message, wherein the corresponding physical position information can be acquired according to the IP address information of a gateway or IP address information, and a subscriber port number which are all carried by a call request, and the physical position of the non-IP fixed terminal is determined based on the above information. In addition, the invention also discloses a system and an access gateway for determining the physical position of the non-IP fixed terminal.

Description

technical field [0001] The invention relates to a method and system for determining the physical location of a user terminal, belonging to the field of IP multimedia subsystem communication. Background technique [0002] IMS (IP Multimedia Subsystem, IP Multimedia Subsystem), proposed by 3GPP in Release 5, is a new telecom network architecture based on an all-IP network and a product of the integration of telecom networks and the Internet. IMS has the characteristics of access independence and end-to-end all-IP, and is an open core network architecture. [0003] Among them, during the IMS communication process, some services require to know the physical location of the user terminal. For example, in the emergency call service, no matter where the user is, the fire alarm number dialed is 119, but it is impossible to hand over all alarms to a fire alarm center, because this puts too much pressure on equipment and personnel, and does not meet the requirements of rapid The nee...
