Embodiment 1
[0077] Figure 7 is a flow chart of PRA processing between PCRF and PCEF according to an optional embodiment of the present invention, such as Figure 7 As shown, the steps of the process include:
[0078] Step S701: The PCEF sends an IP-CAN session establishment indication message to the PCRF, which carries a user identifier.
[0079] Step S702: PCRF reads local configuration, obtains subscription information of the user from SPR, obtains PRA data, makes rule decision, and establishes IP-CAN session.
[0080] Step S703: Send a CCA response message, which includes the PRA and the subscribed PRA reporting event;
[0081] Among them, if the PRA data is obtained, put the PRA identifier and the monitored area PRA element list into the Presence-Reporting-Area-Information AVP, encode the CCA session establishment response message, and send it to PCEF, PCRF and PCEF complete the creation of IP-CAN Session, and save IP-CAN session information and user information on PCRF.

Embodiment 2
[0095] Figure 8is a flow chart of PRA processing between PCRF and TDF according to an optional embodiment of the present invention, such as Figure 8 As shown, the steps of the process include:
[0096] Step S801, PCRF reads local configuration, obtains subscription from SPR, obtains PRA at the same time, and establishes IP-CAN session;
[0097] Step S802, sending a TSR message to establish a TDF session, including PRA and subscribed PRA reporting events;
[0098] Step S803, notifying the UE to report the PRA status where it is located;
[0099] Step S804, the UE reports entering / inside the PRA, or leaving / outside the PRA;
[0100] Step S805, sending a CCR message, carrying a PRA identifier and a PRA status;
[0102] Step S807, sending a CCA response message and ADC rules;
[0103] Step S808, PCRF local configuration or SPR subscription change, triggering PRA change;
[0104] Step S809, triggering ADC re...

Abstract
The present invention provides a processing method and device for area entry and exit monitoring, including: after the session between the first functional entity and the second functional entity in the policy and charging control PCC structure is successfully established, the first functional entity detects and monitors Whether the area PRA identification and / or PRA element list of the region is changed; when the PRA identification and / or PRA element list is changed, the first functional entity encodes the PRA identification and / or PRA element list negotiated with the second functional entity into the new The attribute value in the authentication request RAR message is paired with the AVP, and the RAR message is sent to the second functional entity; the first functional entity receives the re-authentication response RAA message reported by the second functional entity. The present invention solves the problem in the related art that the PCRF cannot send the latest PRA to the PCEF through the RAR message, nor can it report the PRA status in the RAA message in time.
Description
technical field [0001] The present invention relates to the communication field, in particular, to a processing method and device for monitoring an entry and exit area. Background technique [0002] With the continuous evolution of Policy and Charging Control (referred to as PCC) architecture, figure 1 is a schematic diagram of the PCC architecture in related technologies, such as figure 1 As shown, the PCC includes a Policy and Charging Rules Function (Policy and Charging Rules Function, referred to as PCRF), a Policy and Charging Enforcement Function (Policy and Charging Enforcement Function, referred to as PCEF), a bearer binding and event reporting function ( BearingBinding and Event Report Function, referred to as BBERF), traffic detection function (Traffic Detection Function, referred to as TDF), application function (Application Function, referred to as AF), user subscription database (Subscription Profile Repository, referred to as SPR), offline billing system (Off...
