EPS supports the intercommunication with non-3 GPP system.Intercommunication with non-3 GPP system realized by S2a/b/c interfaces, P-GW is as the anchor point between 3GPP and non-3 GPP system.On the system architecture of EPS, as shown in Figure 1.Wherein, non-3 GPP system It is divided into trusted non-3 gpp IP accesses and trustless non-3 gpp IP accesses.Trusted non-3 gpp IP accesses can directly lead to Cross S2a interfaces to be connected with P-GW, which uses proxy-mobile IP version 6（Proxy Mobile IP version 6, referred to as For PMIPv6）Agreement or general packet radio service tunnel agreement（General Packet Radio Service tunnel Protocol, referred to as GTP）Agreement；Trustless non-3 gpp IP accesses packet data gateway that need to be Jing Guo evolution（Evolved Packet Data Gateway, referred to as ePDG）It is connected with P-GW, the interface between ePDG and P-GW is S2b, using PMIPv6 Or GTP agreements, and user equipment（User Equipment, referred to as UE）Internet protocol secure is used between ePDG Property（Intemet Protocol security, referred to as IPSec）Protection is encrypted to signaling and data.S2c provides UE The relevant control of user plane and mobility support between P-GW, its mobility management protocol supported are the shifting for supporting double stacks Dynamic IPv6（Mobile IPv6Support for Dual Stack Hosts and Routers, referred to as DSMIPv6）.

Current problem FMC（Fixed Mobile Convergence, fixed network mobile fusion）, for 3GPP and BBF （Broadband Forum, Broadband Forum）Access network policy unified management is studied.Non-3 GPP access network is refered in particular to as fixed network, Refer in particular to WLAN（WLAN）Access.Four kinds of main scenes of FMC technologies：

（1）H（e）NB scenes.UE passes through Home eNodeB（H（e）NB）The packet-based core networks of core network access evolution （Evolved Packet Core, referred to as EPC）, belong to 3GPP/H（e）The scene of the technology of NB accesses EPC, wherein, H（e） NB occupies fixed network circuit.Dotted line in business data flow such as Fig. 1（a）It is shown.

（2）WLAN-EPC-routed scenes.UE accesses net by WLAN（Fixed network）Access mobile core net EPC, the scene Belong to non-3 gpp（WLAN accesses net/fixed network）Access the technology of EPC.Its basic norm accessed needs to meet above-mentioned EPS supports It is specific to be divided into S2a, S2b and S2c access again with the requirement of the intercommunication of non-3 GPP system.Dotted line in business data flow such as Fig. 1 （b）It is shown.

（3）The WLAN shunt of non-seamless（Non-seamless WLAN offload, referred to as WLAN-NSWO）Scene.UE Access WLAN access nets（Fixed network）, net is accessed by WLAN（Fixed network）Gateway wideband network gateway/Broadband Remote Access Service Device（Broadband network Gateway/Broadband Remote Access Server, referred to as BNG/BRAS）Directly Connect visit external packet data networks（Packet data network, referred to as PDN）.Dotted line in business data flow such as Fig. 1 （c）It is shown.

（4）Fixed equipment（Fixed/BBF device）Scene.Fixed equipment（For example, home videos, WLAN's is fixed whole End, the home gateway of route type（Residential Gateway, referred to as RG）Deng）Access WLAN access nets（Fixed network）, pass through WLAN accesses net（Fixed network）Gateway BNG/BRAS directly visit external packet data networks.Void in business data flow such as Fig. 1 Line（d）It is shown.

Illustrate separately below the main feature of above scene and under four kinds of scenes run business when there are the problem of.

First, H（e）NB scenes

EPS supports Home eNodeB（Home eNodeB, referred to as H（e）NB）Access, H（e）NB is a kind of small-sized, low work( The base station of rate, can be deployed in the indoor place such as family, office and enterprise building.H（e）NB usually passes through the fixed network line of rental The core net of EPS is accessed on road, as shown in Figure 1.In order to ensure the safety of access, security gateway is introduced in core net（Security Gateway, referred to as SeGW）Shielded, H（e）Data between NB and SeGW will be packaged using IPSec.H（e）NB It can also can again pass through H by being directly connected to the MME and S-GW of core net with the ipsec tunnel that SeGW is established（e）NB GW is connected to MME and S-GW, i.e. H（e）NB GW are an optional network elements.Meanwhile in order to realize to H（e）NB is managed, and is introduced Network element home base station management system（Home eNodeB Management System, referred to as HeMS）（Do not show in Fig. 1 Go out）.

In addition, UMTS（Universal Mobile Telecommunications System, universal mobile communications system System）Support Home eNodeB（Home NodeB, referred to as HNB）Access.Use SGSN（Serving General Packet Radio Service Support Node, service universal packet wireless business business support node）S-GW is instead of, uses GGSN （Gateway General Packet Radio Service Supporting Node, gateway general packet radio service branch Serve as a diplomatic envoy a little）It instead of P-GW.

Due to H（e）The QoS of the fixed network circuit of NB accesses is typically to be subject to H（e）The owner and fixed network operator of NB/H B Signing limitation.Therefore, when 3GPPUE passes through H（e）When NB/HNB accesses 3GPP core net access services, required QoS is not It can exceed that the QoS of the signing for the fixed network circuit that fixed network operator can be provided.Otherwise, the QoS of UE access services cannot be protected Barrier, particularly ensures bit rate（Guaranteed Bitrate, referred to as GBR）Business it is even more so.Therefore, for 3GPP , it is necessary to which a set of unified mechanism of control realizes the admission control of user/connection/business for network and fixed network.For example： When there is new business to initiate, only in the case where fixed network ensures there are enough resource/bandwidths, take into account and consider mobile network resource Also under conditions of abundance, the business could be received；Otherwise, the business should just be refused.

In order to realize the management that is uniformly controlled of resource, current solution is by drawing between BNG/BRAS and PCRF The Gxd interfaces entered carry out the resource of managing fixed network circuit, and specific way is：Terminal UE is from H（e）NB is accessed, H（e）NB is place The information of fixed network circuit（Usually H（e）NB local address, port numbers, and the full name domain name of fixed network（Fully Qualified Domain Name, referred to as FQDN）Deng）PCRF is sent to by EPC core nets, BNG is found by PCRF and establishes Gxd interfaces On strategy session, and by Gxd interfaces come consulting tactical information, managing fixed network line resource, admission control is carried out to business.

2nd, WLAN-EPC-routed scenes

WLAN-EPC-routed scenes are similar to H（e）NB scenes, there is also the mechanism of resource management, equally there is also money Source deficiency causes the situation of business operation failure.Currently realizing the specific practice for being uniformly controlled management of resource is：Terminal UE from WLAN accesses EPC, in access procedure, the fixed network line information where terminal UE（Usually UE local address, IPsec ports Number etc.）PCRF is sent to by EPC core nets, BNG is found by PCRF and establishes the strategy session on Gxd interfaces, and passes through Gxd Interface carrys out consulting tactical information, and managing fixed network line resource, admission control is carried out to business.

3rd, WLAN-NSWO scenes

For WLAN-NSWO scenes, two kinds of sub-scenes can be divided into according to the access difference of terminal UE：（1）UE leads to Cross fixed network access authentication；（2）UE is not over fixed network certification.Also all there are the machine of resource management for which kind of sub-scene System, equally there is also the situation that inadequate resource causes business operation failure.The money under fixed network certification sub-scene currently is passed through to UE The specific practice for being uniformly controlled management in source is：Terminal UE is accessed from WLAN, because UE performs certification from fixed network, fixed network BNG/BRAS can perceive the access of UE, and BNG/BRAS can initiate the foundation of the strategy session on Gxd interfaces, pass through the strategy session Carry out consulting tactical information, managing fixed network line resource, admission control is carried out to business.For UE not over fixed network certification subfield Being uniformly controlled for resource under scape is managed referring to four.

4th, fixed equipment（Fixed/BBF device）Scene

Fixed equipment access scene is also classified into several sub-scenes：（1）Fixed equipment passes through fixed network access authentication；（2）It is fixed Equipment is not over fixed network certification；（3）RG scenes.Which kind of sub-scene is also all there are the mechanism of resource management, equally There is a situation where that inadequate resource causes business operation failure.

For RG scenes, when RG is operated under route pattern, it is that can perform access authentication that RG, which is powered on, fixed network BNG/BRAS can perceive the access of RG, and BNG/BRAS can initiate the foundation of the strategy session on Gxd interfaces, pass through the strategy session Come consulting tactical information, managing fixed network line resource, to accessing being set without by fixed network certification movement UE and fixation under the RG Standby business carries out admission control.

For the fixed equipment by fixed network access authentication, the admission control of its resource is analogous to WLAN-NSWO Scape.

For the fixed equipment not over fixed network access authentication, which is connected under RG, its resource management With business admission control completed by the resource management of RG and business admission controlling mechanism.

In conclusion under fixed network circuit, there can be plurality of devices access, the pattern of access again may be different.Different scenes May exist parallel.The resource of fixed network needs rational distribution.Provided according to current agreement, BNG cannot perform the system of resource One control and management, and the PCRF to generate strategy, because there are different access devices and access scene, PCRF may be deposited at the same time Multiple（Such as H（e）The PCRF of the PCRF of NB scenes, WLAN-EPC-routed may not be same）, multiple PCRF controls The resource of the circuit, it may appear that compute repeatedly（Exactly different equipment may be given at the same time with a resource）The problem of so as to leading Cause resource allocation error.
