Problems solved by technology

[0009] In view of this, the main purpose of the present invention is to provide a processing method and system for an IFOM error, so as to solve the problem of failing to apply for resources for the migrated flow in the existing IFOM process, which will lead to failure of the migrated business flow. Problems such as QoS not being guaranteed or even service interruption

Embodiment Construction

[0043] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0044] The processing method when a kind of IFOM error provided by the present invention, such as Figure 4 As shown, it mainly includes the following content: after the routing rule negotiation (step 401) of the flow migration is completed between the UE and the network side in the IFOM process, if there is a QoS resource management-related failure on the network side, the PCRF will notify the failed flow migration information To the home agent (Home Agent) of the UE, trigger the processing operation on the fault (step 402).

[0045] Wherein, the faulty flow migration information may be: flow routing rule (routing rule) information or flow routing rule identifier (routing rule ID). The fault handling operation includes: reselecting the routing path for the flow corresponding to the fault. Specifically, the flow cor...

Abstract

The invention provides a processing method and a system during internet protocol flow migration (IFOM) error. The method includes that after flow migration routing rule negotiation between user equipment (UE) in an IFOM process and a network side is finished, if the network side has related faults of quality of service (QoS) resource management, a policy and charging rules function (PCRF) entity announces flow migration information having faults to a home agent (HA) of the UE and triggers processing operation of the faults. By means of the method and the system, the problems that in the existing IFOM process, the QoS of migrated service flow cannot be guaranteed and even is interrupted and the like under the condition of migrated flow resource application failure is solved.

Description

technical field [0001] The invention relates to IP flow migration (IFOM) technology in the field of communication, in particular to a processing method and system when IFOM is wrong. Background technique [0002] The third generation partnership project (3GPP, 3rd Generation Partnership Project) evolved packet system (EPS, Evolved Packet System) such as figure 1 as shown, figure 1 It is a diagram of EPS network architecture in a non-roaming scenario. The network architecture consists of Evolved Universal Terrestrial Radio Access Network (E-UTRAN, Evolved Universal Terrestrial Radio Access Network), Mobility Management Entity (MME, Mobility Management Entity), service Gateway (S-GW, Serving Gateway), Packet Data Network Gateway (P-GW, Packet Data Network Gateway), Home Subscriber Server (HSS, Home Subscriber Server), Policy and Charging Rules Functional Entity (PCRF, Policy and Charging Rules Function) and other supporting nodes. [0003] An application function entity (AF...
