Description

Network information processing method, device and system

Technical Field

The present invention relates to the field of communications, and in particular, to a method, an apparatus, and a system for processing network information.

Background

An Evolved Packet System (EPS) of the third Generation Partnership Project (3rd Generation Partnership Project (3 GPP) includes an Evolved Universal mobile telecommunications System Terrestrial Radio Access Network (E-UTRAN), a Mobility Management Entity (MME), a Serving Gateway (S-GW), a Packet Data Network Gateway (Packet Data Gateway, P-GW or PDNGW), a Home Subscriber Server (HSS), an Authentication Authorization and Accounting (Authentication, Authorization and Accounting, AAA) Server of the 3GPP, a Policy and Accounting Function (Policy and Accounting functions, PCRF) Entity and other support nodes. The PCRF entity is often referred to as PCRF for short.

Fig. 1 is a schematic diagram of a system architecture of EPS in the related art, in fig. 1, EUTRAN includes a base station eNodeB (not shown in the figure); the MME is responsible for the related work of control planes such as mobility management, the processing of non-access stratum signaling, the management of user mobility management context and the like; the S-GW is an access gateway device connected with the E-UTRAN, forwards data between the E-UTRAN and the P-GW, and is responsible for caching paging waiting data; the P-GW is a border gateway between the EPS and a Packet Data Network (PDN), and is responsible for accessing the PDN and forwarding data between the EPS and the PDN; the S-GW and the P-GW both belong to a core network gateway; the PCRF is connected to an Internet Protocol (IP) Service network through a receiving interface Rx to acquire Service information, and is connected to a gateway device in the network through a Gx interface to initiate establishment of an IP bearer, ensure Quality of Service (QoS) of Service data, and perform charging control.

The EPS also supports Access to Universal Mobile telecommunications system Terrestrial Radio Access Network (UTRAN) and Global system for Mobile communications EDGE Radio Access Network (GERAN) systems. The Serving GPRS Support Node (SGSN) and the S-GW communicate with each other through an S4 interface, and the SGSN communicates with the MME through an S3 interface.

The 3GPP also supports interworking with non-3 GPP systems, where interworking with non-3 GPP systems is implemented through S2a/b/c interface, and the P-GW is not much related to the present invention as an anchor point between 3GPP and non-3 GPP systems, and therefore is not shown in the figure. The non-3 GPP system may be a WLAN (Wireless Local access network).

When a user equipment (ue) (user equipment) performs a certain service, an operator may want to acquire a load condition of a network or a behavior condition of a network used by a user, and accordingly determine how to perform and adjust the service, for example, for services such as advertisements (video clips) in Push (Push) services, if a current network load of a cell is lighter, the services are performed; if the network load is heavy, the service with high QoS requirement (such as voice call) is firstly ensured, and the PUSH type service can be delayed to be developed.

Referring to fig. 2, a Network and user behavior analysis (NBA) device (abbreviated as NBA) is deployed in the Network, and the NBA obtains initial information of the Network and the user through multiple channels (for example, interfaces with Network devices or interworking with a Network management system), analyzes and counts the information, makes an information analysis report for the Network and the user, and reports the information analysis report to the PCRF of the Network through an Xa interface. When the PCRF formulates the policy, the NBA reported information analysis report is considered sufficiently to adjust the QoS, or the execution time, or the service resource authorization, etc. of the service.

In the prior art, only the non-roaming scenario shown in fig. 2 is considered, NBA and PCRF are in the same network domain, and an information analysis report may be reported through the non-roaming interface Xa. When the user is in the roaming scenario as shown in fig. 3 when accessing, the NBA is in the visited domain. Because the interface S5 uses the GTP protocol, under the existing planning definition, the visited domain network does not enable the PCRF (visited PCRF) when the interface S5 uses the GTP protocol. Thus, even though NBA equipment is deployed in the visited network, NBA cannot report to PCRF of the home network after completing the information analysis report (because vprfcr is not enabled for the PDN connection), and NBA information cannot report to hPCRF (HomePCRF, home/home domain PCRF) in the home network across the network (this is not allowed by the operator), so that hPCRF cannot know network information such as network and user behavior information under this condition, and therefore cannot handle QoS adjustment, authorization policy, and the like of the roaming user, and particularly under the condition of network congestion, it cannot guarantee that a high-priority service of the UE operates preferentially, and user experience during roaming is poor.

And the vprff establishes a policy session Xb session to the hPCRF.

The NBA reports an information analysis report to the vPCRF periodically; or the vPCRF periodically queries an information analysis report at the NBA;

next, step a or step B is performed; wherein,

The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings. In order to solve the problems in the related art, according to the network and the statistical analysis of the user behavior, the policy is formulated by the vPCRF, or the policy formulated by the vPCRF for the hPCRF is authorized to adapt to the development of certain services.

Is constructed as

Referring to fig. 4, under the architecture shown in fig. 4, a vpre is enabled, and there is an interface between the vpre and the hPCRF and NBA. The NBA collects network condition information and user behavior information, carries out statistical analysis on the collected information, reports an analysis result to the vPCRF through an Xa interface, the vPCRF adjusts the strategy according to the received analysis result and sends the adjusted strategy to the hPCRF, and then the hPCRF sends the received strategy to the EPS network for execution.

It should be noted that NBA is an abbreviation of Network and user Behavior Analysis function (Network and user Analysis) in the present invention. The NBA is just a name code, and the entity having the network and user behavior analysis functions described above may have other names when standardization or network deployment is performed.

The vPCRF is selected by the hPCRF, the Xb session is initiated and established by the hPCRF, and the Xb session can be an existing S9 session or an enhanced session thereof; the Xa interface can support stateful policy sessions and also stateless information interactions.

Example one

In this embodiment, after the UE accesses through the visited network, under a scenario of establishing a PDN connection of a home route (a default PDN connection, or an additional PDN connection), a method of selecting a vprfcr and establishing a corresponding policy session is described, and after the policy session is established, a relevant operation of making a policy and an authorization policy is discussed, where a relevant flow is shown in fig. 5, and the flow shown in fig. 5 includes the following steps:

step 501, a UE attaches to an Evolved Packet Core (EPC) to establish a first PDN connection, or the UE initiates establishment of an additional PDN connection;

step 502, a policy session Gx session (also called IP-CAN session) is established between the P-GW and the hPCRF.

Step 503 to step 504, triggered by step 502, the hPCRF selects a vPCRF of the vPLMN, and establishes a policy session (Xb session) with the vPCRF.

The hPCRF may select the vprf based on the vPLMN-ID sent to the hPCRF by the visited network in steps 501 and 502, that is, the hPCRF may select the corresponding vPLMN according to the vPLMN-ID, and then select the appropriate vprf in the vPLMN.

According to the trigger of step 502, the hPCRF determines whether a vpre needs to be selected currently. That is, in a scenario where the visited network deploys NBA, the hPCRF needs to select the vpre and establish a policy session with the vpre. This can be achieved by:

1. configuring contract information between operators on the hPCRF. Since the hPCRF acquires the vPLMN-ID of the vPLMN of the visited network, the hPCRF can know that NBA is deployed in the vPLMN according to the configured subscription information, and therefore a policy session needs to be established between the hPCRF and the vPLMN. Thus, the hPCRF actively initiates the establishment of a policy session;

2. in the attach procedure of step 501 or the PDN connection procedure, the plmn actively carries indication information indicating that the plmn deploys NBA. The indication information sequentially reaches P-GW and hPCRF through an attachment or PDN connection establishment flow, and the hPCRF determines that the establishment of the policy session between the hPCRF and the vPCRF needs to be initiated according to the indication information.

Optionally, there are multiple implementations of the indication information, and the indication information may be sent to the hPCRF through a single cell, or as a modifier byte for the vPLMN-ID, or as a modifier byte for other cells.

The interface between the hPCRF and the vPCRF is named as an Xb interface in the invention, and the corresponding policy session is an Xb session. In practical implementation, the existing S9 interface or the enhanced S9 interface can be adopted. That is, in the subsequent standard work, the interface can still be called as the S9 interface, and the function is slightly enhanced for the S9 interface.

In the flow of the embodiment, the session establishment procedure of the Xb interface includes the two messages shown, and in a specific implementation, the session establishment procedure may include more than two messages, and the specific number of messages depends on the corresponding implementation method.

Steps 505 to 506, triggered by step 503, the pcrf establishes a policy session (Xa session) with the NBA of the vPLMN.

In the invention, the Xa interface is a substitute term, and the name adopted in the specific standard does not influence the essence of the invention.

In this embodiment, it is assumed that the policy session on the Xa interface is a stateful policy session, that is, a lifetime is maintained between the vprfcr and the NBA, and there is a policy session negotiating a context, which is maintained during the existence of the PDN connection and serves the PDN connection.

The vPCRF and the NBA belong to the same network, and the search of the vPCRF for the NBA can be realized through network configuration or other non-standardized modes.

In steps 507 to 508, the NBA collects the status information and statistical information of wireless, wired line, device, and user from the specific device network element or network management system, and performs statistics and analysis on the collected information to generate an information analysis report. The generation of the information analysis report may be in real-time or quasi-real-time.

Wherein, there is no triggering relationship and precedence relationship between step 507 and step 506.

In step 509, the NBA reports the information analysis report to the pcrf through the Xa session. Wherein, the reporting can be realized by the periodical active reporting of a timer on the NBA or triggered by a subscription event; the method can also be implemented by a periodic request of a timer on the vPCRF or a request triggered by a subscription event.

Step 510, the pcrf adjusts the current policy according to the information analysis report reported by the NBA, for example, in a network idle scenario, a low-priority service is allowed to be developed; in a scene that the network is busy, only some high-priority services are allowed to be developed, and some low-priority services are rejected.

Step 511, the vPCRF sends the adjusted policy to the hPCRF through the Xb session;

step 512, the hPCRF sends the received policy to the EPS network for execution;

in step 513, the EPS network executes the policy.

Through the steps, the vPCRF adjusts the policy according to the analysis of the network state and the user behavior, the development of high-priority services is preferentially ensured, the services of high-priority users are preferentially ensured, and more refined network management is realized.

Example two

Referring to fig. 6, a scenario and a mechanism of this embodiment are basically the same as those of the first embodiment, and are different in that information interworking between NBA and vprff is no longer implemented by a stateful policy session, but stateless information interworking is adopted, and a flow shown in fig. 6 includes the following steps:

step 601 to step 604, and step 501 to step 504;

605 to 606, 507 to 508;

step 607, this step represents the main difference between this embodiment and the first embodiment: and the NBA and the vPCRF interface.

Specifically, in the first embodiment, a stateful policy session is established through step 505 and step 506, so that the information analysis report can be reported by modifying the Xb interface policy session; in this embodiment, there is no policy session between the NBA and the vprff, so the reporting manner of the information analysis report is as follows: the vPCRF is acquired from the NBA at regular time or is acquired from the NBA based on event triggering.

Step 608 to step 611, and step 510 to step 513.

EXAMPLE III

Referring to fig. 7, this embodiment explains a working mechanism in which a network side initiates an application, an hPCRF makes a policy, and a vprff authorizes the policy. The flow shown in fig. 7 includes the following steps:

step 701, the UE has attached to the EPS network and has established one or more PDN connections;

an Xb session is established between the vPCRF and the HPCRF; and a stateful Xa session is established between the NBA and the vPCRF, or a stateless information interaction mode is adopted.

In steps 702 to 703, NBA collects the status information and statistical information of wireless, wired line, device, and user from the specific device network element or network management system, and performs statistics and analysis on the collected information to generate an information analysis report. The generation of the information analysis report may be in real-time or quasi-real-time.

Wherein, there is no triggering relationship or precedence relationship between step 702 and step 704.

Step 704 to step 705, the network side initiates a service, the AF (Application Function) entity pushes service description information to the hPCRF, and the hPCRF makes a policy according to the service description information.

Step 706, the hPCRF sends the formulated policy to the vprff to request authorization;

in steps 707 to 708, the pcrf reviews and adjusts the policy for requesting authorization according to the information analysis report periodically reported by the NBA (for the case of the first embodiment) or the information analysis report actively queried from the NBA (for the cases of the first and second embodiments).

Step 709, the vPCRF feeds back the authorized policy to the hPCRF through the Xb interface;

step 710 to step 711, the hPCRF issues the authorized policy to the P-GW, and the EPS network executes the policy.

The above described procedure is that the vpre authorizes the policy of the hPCRF. If the service with not high priority requirement (such as the push service of mobile operators such as advertisement short-cut) can be temporarily stopped when the network state is busy, the vprf rejects the request for policy authorization from the hPCRF, and the hPCRF can reinitiate the authorization request when the network state is no longer busy.

Framework two

Referring to fig. 8, under the architecture shown in fig. 8, a vpre is enabled, and there is an interface between the vpre and the hPCRF and NBA. The NBA collects network condition information and user behavior information, carries out statistical analysis on the collected information, reports an analysis result to the vPCRF through an Xa interface, the vPCRF adjusts the strategy according to the received analysis result and sends the adjusted strategy to the hPCRF, and then the hPCRF sends the received strategy to the EPS network for execution.

The vPCRF is selected by the S-GW, and the S-GW triggers the vPCRF to initiate the interaction of the Xa interface and the Xb interface through the Xc interface; the Xb interface session is initiated and established by the vPCRF towards the hPCRF, and the Xb session can be an existing S9 session or an enhanced session thereof; the Xa interface can support stateful policy sessions and also stateless information interactions.

Example one

In this embodiment, a method for selecting a vprfcr and establishing a corresponding policy session in a scenario where a home-routed PDN connection (a default PDN connection or an additional PDN connection) is established after the UE accesses through a visited network is provided, and a relevant operation of making a policy and an authorization policy after the policy session is established is discussed, where a relevant process is shown in fig. 9, where the process shown in fig. 9 includes the following steps:

step 901 to step 902, and step 501 to step 502;

step 903, in the process of attaching or establishing PDN connection, the S-GW selects the vprff, and triggers the vprff to initiate policy session establishment through the Xc interface.

And step 904, triggered by step 903, the vprff initiates a policy session establishment (Xb session) request to the vprff of the hPLMN, and establishes an Xb policy session.

Step 905 to step 913, and step 505 to step 513.

Example two

Referring to fig. 10, a scenario and a mechanism of this embodiment are basically the same as those of the first embodiment, and are different in that information interworking between NBA and vprff is no longer implemented by a stateful policy session, but stateless information interworking is adopted, and a flow shown in fig. 10 includes the following steps:

1001 to 1004, and 901 to 904;

step 1005 to step 1006, synchronization step 907 to step 908;

step 1007, this step represents the main difference between this embodiment and the first embodiment: and the NBA and the vPCRF interface.

Specifically, in the first embodiment, a stateful policy session is established through the steps 905 and 906, so that the information analysis report can be reported by modifying the Xb interface policy session; in this embodiment, there is no policy session between the NBA and the vprff, so the report of the information analysis report is: the vPCRF is acquired from the NBA at regular time or is acquired from the NBA based on event triggering.

Steps 1008 to 1011, and steps 910 to 913.

EXAMPLE III

Referring to fig. 11, this embodiment explains a working mechanism in which a network side initiates an application, an hPCRF makes a policy, and a vprff authorizes the policy. The process shown in fig. 7 is the same as that of the third embodiment in the first architecture (corresponding to fig. 7).

Framework three

Referring to fig. 12, under the architecture shown in fig. 12, a vpre is enabled, and there is an interface between the vpre and hPCRF and NBA. The NBA collects network condition information and user behavior information, carries out statistical analysis on the collected information, reports an analysis result to the vPCRF through an Xa interface, the vPCRF adjusts the strategy according to the received analysis result and sends the adjusted strategy to the hPCRF, and then the hPCRF sends the received strategy to the EPS network for execution.

After the UE attaches to the network or establishes a PDN connection, the UE or an eNB/MME/SGSN/S-GW that senses UE access sends a notification to the NBA, where the notification carries information related to the PDN connection of the user, such as: a user identity, an Access Point Name (APN), a PDN Connection (Connection) ID, a Home Public Land Mobile Network (HPLMN) ID, etc. And the NBA is triggered to actively select the vPCRF and establish the Xa session with the vPCRF. The subscriber identity may be (IMSI, International Mobile subscriber identity) or NAI.

The Xb session is initiated and established by the vprff, and may be an existing S9 session or an enhanced session thereof.

Example one

In this embodiment, a method for selecting a vprfcr and establishing a corresponding policy session in a scenario where a UE is attached to an EPC network or a scenario where a PDN connection is newly established is provided, and a related operation of formulating a policy and an authorization policy after the policy session is established is discussed. Related process referring to fig. 13, the process shown in fig. 13 includes the following steps:

step 1301, the UE attaches to the EPC to establish a first PDN connection, or the UE initiates establishment of an additional PDN connection;

in step 1302, a policy session Gx session (also called IP-CAN session) is established between the P-GW and the hPCRF.

Step 1303, the UE or eNB/MME/SGSN/S-GW that senses UE access sends a notification to the NBA, where the notification carries information related to the PDN connection of the user, such as: user identity, APN, PDN Connection ID, HPLMN ID, etc.

In steps 1304 to 1305, the NBA is triggered by step 503, selects the vprff, and establishes an Xa session with the vprff.

Step 1306, the vrcf establishes Xb policy session with the hPCRF.

Step 1307 to step 1308, the NBA collects the state information and statistical information of wireless, wire line, device, and user from the specific device network element or network management system, and performs statistics and analysis on the collected information to generate an information analysis report. The generation of the information analysis report may be in real-time or quasi-real-time.

Wherein, there is no triggering relationship or precedence relationship between step 1307 and step 1306.

In step 1309, the NBA reports the information analysis report to the pcrf through the Xa session. Wherein, the reporting can be realized by the periodical active reporting of a timer on the NBA or triggered by a subscription event; the method can also be implemented by a periodic request of a timer on the vPCRF or a request triggered by a subscription event.

Step 1310, the pcrf analyzes the report according to the information reported by the NBA, and adjusts a current policy, for example, in a network idle scenario, a low-priority service is allowed to be developed; in a scene that the network is busy, only some high-priority services are allowed to be developed, and some low-priority services are rejected.

Step 1311, the vrpcrf sends the adjusted policy to the hPCRF through the Xb session;

step 1312, the hPCRF sends the received policy to the EPS network for execution;

in step 1313, the EPS network executes the policy.

step 1401, the UE has attached to the EPS network and has established one or more PDN connections;

an Xb session is established between the vPCRF and the HPCRF; an Xa session is established between NBA and vPCRF.

Step 1402 to step 1403, the NBA collects the state information and statistical information of wireless, wire line, device, and user from the specific device network element or network management system, and performs statistics and analysis on the collected information to generate an information analysis report. The generation of the information analysis report may be in real-time or quasi-real-time.

There is no triggering relationship or precedence relationship between step 1402 and step 1404.

Step 1404 to step 1405, the network side initiates a service, the AF pushes service description information to the hPCRF, and the hPCRF makes a policy according to the service description information.

Step 1406, the hPCRF sends the formulated policy to the vprff to request authorization;

in steps 1407 to 1408, the pcrf checks and adjusts the policy requesting authorization according to the information analysis report periodically reported by the NBA or the information analysis report actively queried from the NBA.

Step 1409, the vPCRF feeds back the authorized policy to the hPCRF through the Xb interface;

step 1410 to step 1411, the hPCRF issues the authorized policy to the P-GW, and the EPS network executes the policy.
