Embodiment Construction

[0070] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0071] For ease of reference in the more detailed description below, it should be noted that:

[0072] (1). If image 3 As shown, in order to solve the cell congestion problem, 3GPP (abbreviation of generation partnership project, third generation partnership project) proposes to introduce RCAF (abbreviation of RAN Congestion Awareness Function, RAN (abbreviation of Thethirdradioaccessnetwork, radio access network) congestion awareness function) network element in the network , based on traditional UPCON (abbreviation for Userplane congestion, user plane congestion), the information of congested cell information is obtained, and then used for PCRF to perform corresponding policy control.

[0073] 1. When a congestion event occurs in a cell, the OAM (abb...

Abstract

The invention provides a method and a device for obtaining real-time position information of user equipment, wherein the method for obtaining the real-time position information of the user equipment is applied to a PCRF (Policy and Charging Rule Function) entity; the method comprises the following steps: sending a user information subscription request to MME (Mobility Management Entity) / SGSN (Serving GPRS (General Packet Radio Service) Support Node) via an information transfer channel having a predetermined interface, wherein the user information subscription request comprises cell list information of a predetermined area to be subscribed by the PCRF entity; and receiving a subscription response message of the user information subscription request with an MME / SGSN reply, and obtaining the real-time position information of the user equipment from the subscription response message, wherein the subscription response message includes user list information inquired according to the user information subscription request via the MME / SGSN and feeding back all cell ID (Identification) affiliated in the cell list information and user ID of the affiliated cells. The method and the device disclosed by the invention obtain the user list information in a special area through inquiring the user information in a request area from the MME via the PCRF.

Description

technical field [0001] The present invention relates to the core network field, in particular to a method and device for acquiring real-time location information of user equipment. Background technique [0002] In the current Long Term Evolution LTE system, the event subscription capability of PCRF (abbreviation of Policy and Charging Rule Function, Policy and Charging Rule Unit) is defined. For concerned users, PCRF can subscribe a series of events to PGW (abbreviation of Packet Gateway, packet data gateway) to monitor the state change information of these users. For example, the PCRF can monitor the change information of the TAI (abbreviation of TrackingAreaIdentity, tracking area identifier) ​​where the UE (abbreviation of userEquipment, user equipment) is located by subscribing to the TAI_CHANG event of tracking area identifier change. [0003] When PCRF initiates a location information query, the real-time location change information of the monitoring UE can be obtaine...
