Problems solved by technology

In this way, even if the NBA device is deployed on the visiting domain network, the NBA cannot report the information analysis report to the PCRF of the local network (because vPCRF is not enabled for the local PDN connection), and the NBA information cannot be reported across the network to the home network hPCRF (Home PCRF, hometown / home domain PCRF) (this is not allowed by the operator), so in this case hPCRF cannot obtain network information such as network and user behavior information, so it cannot handle QoS adjustment and authorization of roaming users Policies, etc., especially in the case of network congestion, cannot guarantee the priority operation of UE's high-priority services, and the user experience during roaming will deteriorate

Embodiment 1

[0093] In this embodiment, after the UE accesses through the visited network, the method of selecting vPCRF and establishing the corresponding policy session in the scenario of establishing a home-routed PDN connection (default PDN connection, or additional PDN connection), and discusses the policy session After establishment, formulate related operations of policies and authorization policies, see related procedures Figure 5 , Figure 5 The flow shown includes the following steps:

[0094] Step 501, the UE attaches to the evolved packet core network (evolved Packet Core, EPC), establishes the first PDN connection, or the UE initiates the establishment of an additional (additional) PDN connection;

[0095] In step 502, a policy session Gx session (also referred to as an IP-CAN session) is established between the P-GW and the hPCRF.

[0096] From step 503 to step 504, triggered by step 502, the hPCRF selects the vPCRF of the vPLMN, and establishes a policy session (Xb sessio...

Embodiment 2

[0117] see Figure 6 , the scenario and mechanism of this embodiment are basically the same as the first embodiment, the difference is that the information intercommunication between NBA and vPCRF is no longer implemented through stateful policy sessions, but uses stateless information intercommunication, Figure 6 The flow shown includes the following steps:

[0118] Step 601 to step 604, same as step 501 to step 504;

[0119] Step 605 to step 606, same as step 507 to step 508;

[0120] Step 607, this step embodies the main difference between this embodiment and Embodiment 1: the interaction mode between the NBA and the vPCRF interface.

[0121] Specifically, in Embodiment 1, a stateful policy session is established through steps 505 and 506, so the information analysis report can be reported by modifying the Xb interface policy session; and in this embodiment, there is no policy between NBA and vPCRF session, so the reporting method of the information analysis report is: ...

Embodiment 3

[0124] see Figure 7 , this embodiment describes the working mechanism of the network side initiating the application, the hPCRF formulating the policy, and the vPCRF authorizing the policy. Figure 7 The flow shown includes the following steps:

[0125] Step 701, the UE has attached to the EPS network and established one or more PDN connections;

[0126] An Xb session has been established between the vPCRF and the HPCRF; a stateful Xa session has been established between the NBA and the vPCRF, or a stateless information exchange method is adopted.

[0127] From step 702 to step 703, the NBA collects status information and statistical information of wireless, wired lines, equipment, and users from specific equipment network elements or network management systems, and performs statistics and analysis on the collected information to generate an information analysis report. The generation of the information analysis report may be real-time or quasi-real-time.

Abstract

Disclosed are a network information processing method, an apparatus and a system. When an S5 interface uses a GTP protocol, a vPCRF is enabled on a visited network; a session is established between the vPCRF and an hPCRF on a home network, and a session is established between the vPCRF and an NBA device; the vPCRF obtains an information analysis report from the NBA; a session is established between a P-GW and the hPCRF, and the session triggers the hPCRF to select the vPCRF; and the vPCRF determines, according to the information analysis report, a policy to be executed on an EPS network. A network information processing technology in the present invention can provide a roaming user with network information that involves network and user behaviors so as to determine a more accurate and detailed control policy to be executed on the EPS network for a UE service, which ensures that services at different levels are considered differently, implements refine management of a service and is more beneficial to service development.

Description

technical field [0001] The present invention relates to the communication field, in particular to a network information processing method, device and system. Background technique [0002] The Evolved Packet System (EPS) of the 3rd Generation Partnership Project (3GPP) includes the Evolved Universal Terrestrial Radio Access Network (E-UTRAN) , Mobility Management Entity (MME), Serving Gateway (Serving Gateway, S-GW), Packet Data Network Gateway (Packet Data Network Gateway, P-GW or PDN GW), Home Subscriber Server (HomeSubscriber Server, HSS) , 3GPP authentication, authorization and accounting (Authentication, Authorization and Accounting, AAA) server, policy and charging rules function (Policy and Charging Rules Function, PCRF) entity and other supporting nodes. The PCRF entity is generally referred to as PCRF for short. [0003] figure 1 It is a schematic diagram of the system architecture of the EPS in the related art, figure 1 Among them, EUTRAN includes base station e...
