Problems solved by technology

[0006] The embodiment of the present invention provides a method and device for subscribing to the location information of terminal equipment, which is used to solve the problem in the current technology that the gateway equipment frequently reports the location information of the terminal equipment when the terminal equipment switches between serving cells, which makes the transmission in the network system invalid. Increased signaling wastes network system resources and degrades device performance

Embodiment 1

[0080] Such as figure 1 The above is a schematic flowchart of a method for subscribing to location information of a terminal device provided by Embodiment 1 of the present invention. The method can be described as follows.

[0081] Step 101: The policy and charging rule function PCRF receives the authorization request message sent by the gateway device.

[0082] Wherein, the authorization request message includes the location information of the terminal device currently accessing the gateway device.

[0083] In step 101, when the terminal device sends an IP-CAN (IP-Connectivity Access Network, IP connection access network) establishment request message to the gateway device, the gateway device determines the location information of the terminal device accessing the gateway device.

[0084] Wherein, the manner in which the terminal device sends the IP-CAN establishment request message to the gateway device may be through an IP-CANEstablish Request message, or through other me...

Embodiment 2

[0144] Such as figure 2 As shown, it is a schematic flowchart of a method for subscribing to terminal device location information provided by Embodiment 2 of the present invention. Embodiment 2 of the present invention is an invention under the same inventive concept as Embodiment 1 of the present invention. The method can be as follows stated.

[0145] Step 201: the gateway device sends an authorization request message to the Policy and Charging Rules Function PCRF.

[0146] Wherein, the authorization request message includes the location information of the terminal device currently accessing the gateway device.

[0147] In step 201, when the terminal device sends an IP-CAN (IP-Connectivity Access Network, IP connection access network) establishment request message to the gateway device, the gateway device determines the location information of the terminal device accessing the gateway device.

[0148] Wherein, the manner in which the terminal device sends the IP-CAN estab...

Embodiment 3

[0195] Such as image 3 As shown, it is a schematic flowchart of a method for subscribing to terminal device location information provided by Embodiment 3 of the present invention. Embodiment 3 of the present invention is an invention under the same inventive concept as Embodiment 1 to Embodiment 2 of the present invention. The method can be described as follows.

[0196] Assume that the identification of area 1 is RAI1 (the first type area or controlled area), the identification of area 2 is RAI2 (the second type area or uncontrolled area), and the identification of area 3 is RAI3 (the first type area or controlled area). area), area 4 is identified as RAI4 (a second-type area or non-administrative area), area 1 contains two service cells A and B, area 2 contains two service cells C and D, area 3 A serving cell E is included, and a serving cell F is included in area 4.

[0197] Wherein, if in the 2G communication system, the identifier of the serving cell A is CGI1, the ide...

Abstract

The invention discloses a method and device for subscribing to location information of a terminal device, comprising: policy and charging rule function PCRF receives an authorization request message sent by a gateway device and includes the location information of the terminal device currently accessing the gateway device, and according to the location information The corresponding relationship with the location trigger, determining the location trigger corresponding to the location information contained in the received authorization request message, sending the determined location trigger to the gateway device, and the location trigger is used to instruct the gateway device Report the location information of the terminal device according to the location information reporting rules configured for the location trigger. Since the reporting rules of the location information set in the location trigger are different, the number of times the gateway device reports the location information of the terminal device can be effectively reduced, and further The transmission of invalid signaling in the network system is reduced, and the working performance of the system equipment is increased.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for subscribing to location information of terminal equipment. Background technique [0002] With the development of communication network technology, more and more users use smart terminal devices to access the Internet through gateway devices of 3GPP (3rd Generation Partnership Project, third-generation mobile communication standardization organization) or LTE (Long Term Evolution, Long Term Evolution) communication system. [0003] Among them, the PCRF (Policy Control Charging Rules Function, policy and charging rule function) device reports the location information of the terminal device according to the gateway device (for example: GGSN (Gateway GPRS Support Node, gateway GPRS support node) device) that the terminal device accesses. , to detect the service data flow generated by the terminal equipment, and issue the terminal equipme...
