Problems solved by technology

[0023] In the above-mentioned second method, due to the large number of rules sent each time, it is not necessary to send at the time point of each busy-idle transition, but its control mechanism is complicated, and, in the long run, the number of Gx messages sent is still more
[0024] In this way, at the time point of each busy-idle transition, due to the existence of a large number of UEs, a large number of PCC rules need to be reconfigured, resulting in a burst of instantaneous Gx messages, causing signaling impact on PGW and PCRF

Embodiment 1

[0047] In order to avoid the Gx message burst at the time point of switching between busy and idle, this embodiment 1 provides a control method for PCC rule switching, such as Figure 5 As shown, the method includes:

[0048] 510: The PCRF sends a Gx message, where the Gx message includes: a PCC rule, and a rule activation time, a rule deactivation time, and a rule repetition period of the PCC rule.

[0049]Wherein, the Gx message may be a CCA message or a RAR message or the like. The rule activation time Rule-Activation-Time and the rule deactivation time Rule-Deactivation-Time are used to define the execution time of the PCC rule, both of which are absolute times. The regular repetition period Repetition-Time can be 1 hour, 1 day, 1 week, etc., and is preferably 1 in this embodiment.

[0050] 520: The PGW receives the Gx message, and repeatedly executes the PCC rule according to the rule activation time, rule deactivation time, and rule repetition period of the PCC rule. ...

Embodiment 2

[0058] Embodiment 2 is described based on Embodiment 1. In order to further reduce the number of Gx messages issued by the PCRF, in this embodiment, one Gx message includes all PCC rules sent by the PCRF to the PGW, and the corresponding The rule activation time, rule deactivation time and rule repetition period of each of the PCC rules. In this way, the PCRF only needs to send the Gx message once, and the PGW can obtain all required PCC rules and execute them repeatedly according to the repetition period, which is more conducive to avoiding the occurrence of Gx message bursts.

Embodiment 3

[0060] This embodiment provides a PCC rule switching control system, including a PCRF and a PGW.

[0061] The PCRF is used to send a Gx message, and the Gx message includes: a PCC rule, and a rule activation time, a rule deactivation time, and a rule repetition period of the PCC rule. The regular repetition period is 1 hour, 1 day or 1 week.

[0062] The PGW is configured to receive the Gx message, and repeatedly execute the PCC rule according to the rule activation time, rule deactivation time and rule repetition period of the PCC rule.

[0063] In the system described in this embodiment, the PCRF adds a rule repetition period to the issued Gx message, so that the PGW can receive the Gx message once, and then execute the PCC rule repeatedly within the corresponding rule execution time period according to the rule repetition period, thereby avoiding the need for PCRF Repeatedly sending the Gx message at the time point of switching between busy and idle time causes the problem...

Abstract

The invention discloses a control method for (policy and charging control) PCC rule switching and a system thereof, and relates to the field of communication. The method comprises the following steps: A policy and charging rule entity PCRF sends a GX message. The GX message comprises a PCC rule, a rule activation time of the PCC rule, a rule deactivation time and a rule repetition period. A packet data network gateway (PGW) receive the Gx message, and executes the PCC rule repeatedly according to the rule activation time, the rule deactivation time and rule repetition period of the PCC rule. According to the method and the system, phenomenon that at transition time points from busy time to idle time, the PCRF sends the Gx message repeatedly, which leads to outburst of the Gx messages, are avoided, and signaling loads of the PGW and the PRCF are reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a control method and system for PCC (POLICY AND CHARGING CONTROL, policy charging control) rule switching. Background technique [0002] In the PCC architecture of 3GPP, such as figure 1 As shown, the core network element PGW (PACKET DATA NETWORK GATEWAY, packet data network gateway) and PCRF (POLICY AND CHARGING RULE FUNCTION, policy and charging rule entity) interact through the Gx interface to establish IP-CAN (IP CONNECTIVITY ACCESS NETWORK, IP connection access network) session, execute policy control, in PGW and PCRF, Session ID uniquely identifies an IP-CAN session. [0003] Specifically, such as figure 2 As shown, when the user attaches or the PDN (PACKET DATA NETWORK, Packet Data Network) connection is established, the PGW requests the PCRF to perform the PCC authorization of the session establishment through the CCR-I (Credit Control Request-Initial, C...
