Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made belongs to the scope of protection of the invention.
In order to provide more preferable service to user equipment, 3GPP proposes the access way of a variety of user equipmenies, wherein it is exactly one kind therein to access EPC by Home eNodeB mode.
Fig. 1 is the Home eNodeB access network system architecture diagram that 3GPP is defined, as shown in Figure 1：The network system architecture includes Home eNodeB, broadband home network, BBF networks and EPC, wherein, BBF networks serve as backhaul network in such a system.
The main network elements of Home eNodeB access architecture are as follows：
3GPP Femto:Home eNodeB, such as Home NodeB, Home eNodeB (HeNB, family
Front yard base station）
Security Gateway:(SeGW, security gateway) security gateway is located at the edge of mobile core network, for ensuring legal Home eNodeB access mobile core net, Home eNodeB is authenticated, and sets up secure tunnel between Home eNodeB carries out data transmission.
HeNB Gateway:(HeNB GW, femto gateway) is used to converge multiple Home eNodeB to an interface, typically closes and sets with safety net.
Broadband Policy Contrail Function:(BPCF, broadband policy controlled entity) is similar to the PCRF in mobile core network, realizes that the qos policy in BBF networks is formulated and is handed down to BNG execution.
When Home eNodeB is attached to BBF networks, BBF networks are authenticated Home eNodeB as a common fixed broadband network terminal, IP address distribution.Home eNodeB is obtained behind the local IP addresses of BBF network allocations, and IPSec Tunnel (Internet Protocol Security Tunnel, the Internet protocol security tunnel are set up with local ip address and SeGW）.It is identical with the flow for being attached to EPC when UE is attached to Home eNodeB, by PGW (Packet data network Gateway, packet data gateway）For UE distribution IP addresses.
Home eNodeB is accessed to be accessed with macro base station, and (Evolved Universal Terrestrial Radio Access Network, the general land of evolution is wireless by such as E-UTRAN）Difference be that backhaul network is different.Backhaul network refers to base station and equipment of the core network（Such as SGW (Serving Gateway, gateway）, MME (Mobility Management Entity, mobility management entity)) between transmission network.
The backhaul network of macro base station is usually mobile operator proprietary network or the special line for renting fixed operator, the backhaul network is due to being dedicated network, generally will not congestion, QoS (the Quality of Service, service quality such as the bandwidth time delay of business）Parameter can be guaranteed, therefore extra QoS controls need not be carried out to the node inside backhaul network.
The backhaul network of Home eNodeB is to use BBF networks.Due to the non-dedicated network of the network, congestion may be produced, it is therefore necessary to QoS controls are carried out to backhaul network, to ensure the QoS demand of business.
Under the scene of Home eNodeB access, PCRF formulates corresponding qos policy for UE service, is sent to BPCF, and BPCF forwards qos policy to be performed to BNG.Due to being deposited between Home eNodeB and security gateway
In secure tunnel, all data flows (i.e. the data flow transmitted between UE and PGW) encapsulate into IPsec tunnels transmission by Home eNodeB and security gateway, due to adding the address information at secure tunnel two ends in the message after IPsec is encapsulated, this is resulted in after PCRF issues qos policy to BBF networks, and the BNG in BBF networks can not be according to business stream information (original source address and the destination address in QoS rules）Corresponding Business Stream is matched, leads to not carry out correct QoS controls.
3GPP it is also proposed the network architecture that user equipment is connected to EPC by fixed network, and IPsec tunnel buildings are in UE and ePDG (Evolved Packet Data Gateway, evolution packet data gateway）Between, equally exist after PCRF issues qos policy to BBF networks, BNG in BBF networks can not match corresponding Business Stream according to the business stream information (original source address and destination address) in QoS rules, lead to not carry out the problem of correct QoS is controlled, do not praise state herein.
Fig. 2 is a kind of flow chart of information acquisition method provided in an embodiment of the present invention, as shown in Fig. 2 this method includes：
Step 201, receive and first service quality control information is included in strategy session request message, strategy session request message.
During the Internet protocol security tunnel foundation or Home eNodeB is to during home base station management system send configuration information request message, first service quality control information dynamic memory is into described information service unit.
When user equipment adheres to or switches to Home eNodeB, PCRF entities, which are received, comes from PGW or SGW or H-PCRF (Home PCRF, home domain policy control and charging rule functions）The strategy session request that entity is initiated；Or
When user equipment adheres to or switches to mistrustful non-3 GPP access, the strategy session request initiated from PGW entities is received.
In both above situation：
Strategy session request can be specifically that strategy session sets up request or strategy session modification request, including：IP-CAN (does view connection access to network conversation in Internet Protocol Connect Access Network, internet ten）One kind in session or S9 sessions or gateway control session or S9* sessions；
First service quality control information in strategy session request message includes the HeNB marks or UE marks of the user equipment access network；HeNB marks can be the IP address of Home eNodeB ID or Home eNodeB herein, and UE marks can be the IP address of user equipment ID or user equipment.
Step 202, information inquiring request message is sent to information service unit, and the first service quality control information received is included in information inquiring request message.
In this step, PCRF sends information inquiring request message and gives information service unit, and first service quality control information (home eNodeB identifies or the customer equipment identification set up and received in request or strategy session modification request from strategy session are included in the information inquiring request message）.
Bu Sudden 203, obtain the second service quality control information that information service unit feeds back according to the first service quality control information included in information inquiring request message.
During the Internet protocol security tunnel foundation or Home eNodeB is to during home base station management system send configuration information request message, information service unit also dynamic memory second service quality control information while first service quality control information in dynamic memory, described second service quality control information is Home eNodeB by encapsulation with the information of core net or user equipment with the Internet protocol security tunnel between core net, specifically include the IP address information of two, tunnel end points, tunnel head length information, Security Parameter Index information（Security Parameters Inde), port numbers and encapsulation format etc..
Now, in this step, information service unit is by the first service quality control information included in the information inquiring request message received from step 202 as index, and the corresponding second service quality control information of lookup is the IPsec tunnel informations between secure tunnel and feeds back to PCRF.
Using the method in Bu of embodiment of the present invention Sudden 201 ~ 203, accessed in existing user equipment by Home eNodeB or fixed network under the EPC 3GPP network architectures, PCRF, which results in the business stream information being encapsulated in IPsec tunnels and formulates corresponding qos policy, is handed down to backhaul network, BNG in backhaul network goes out corresponding Business Stream according to the Business Stream information matches received, correct QoS controls are carried out, the business experience effect of user is effectively raised.
