Abstract

The invention provides a method and a system for controlling mobile terminal access services and a DRA (diameter routing agent). The method includes that the DRA receives a Diameter request message transmitted by a second network entity and searches a pre-stored DRA binding according to a UE (user equipment) IP (internet protocol) address and a port number subset or a UE IP address and a port number carried by the Diameter request message, so that a policy control server selected by a first network entity is found. By the method, the pre-stored DRA binding is searched from the DRA, and the second network entity is guaranteed to find the policy control server selected by the first network entity, so that the problem that a BPCF (broadband policy control function) and a mobile network AF (application function)/TDF (traffic detection function) or a BNG (broadband network gateway)/BRAS (broadband remote access server) and an AF/TDF of a fixed network select the same policy control server is solved, and a mechanism that related network elements select the same policy control server is enhanced.

Description

A kind of control method of mobile terminal accessing business, system and DRA

Technical field

The present invention relates to the mobile communication technology field, relate in particular to a kind of control method, system and Diameter route agent (Diameter Routing Agent, DRA) of mobile terminal accessing business.

Background technology

Third generation partner program (3rd Generation Partnership Project, the grouping system of evolution 3GPP) (Evolved Packet System, EPS) by Universal Terrestrial Radio Access Network (the Evolved Universal Terrestrial Radio Access Network of evolution, E-UTRAN), mobile management entity (Mobility Management Entity, MME), gateway (Serving Gateway, S-GW), grouped data network gateway (Packet Data Network Gateway, P-GW) and home subscriber server (Home Subscriber Server, HSS) form.

EPS supports the interworking architecture with non-3 GPP access network, and specifically with reference to figure 1, wherein, the intercommunication of EPS and non-3 GPP system is by the S2a/b/c Interface realization, and P-GW is as the anchor point between 3GPP and non-3 GPP system.In Fig. 1, non-3 GPP system is divided into trustless non-3 GPP access network and trusted non-3 GPP access network; Wherein, trustless non-3 GPP access network need link to each other with P-GW through the packet data gateway (Evolved Packet Data Gateway, ePDG) of evolution, and the interface between ePDG and P-GW is S2b; The non-3GPP access of trusted can directly be connected with P-GW by the S2a interface, and the S2a interface adopts the PMIP agreement to carry out information interaction; In addition, the S2c interface provides user terminal (User Equipment, UE) with P-GW between relevant control and the mobility support of user's face, be to be understood that, here use UE to replace aforesaid portable terminal to describe, the mobility management protocol of its support is for supporting mobile IP v 6 (the Moblie IPv6 Support for Dual Stack Hosts and Routers of two stacks, DSMIPv6), it can be used for trustless non-3 GPP system Access Network and trusted non-3 GPP access network.

Wherein, WLAN (Wireless Local Area Network, WLAN) can be used as non-3 GPP system access EPS, this relates to the interconnection and interflow problem of the fixed network mobile fusion (Fixed Mobile Convergence, FMC) of a lot of operators concern.

In the stage two, FMC mainly studies the problem relevant with service distributing.Because the diversity demand of customer service, the user can access multiple business simultaneously, and these professional resource requirements are different; If all portable terminals all are linked into the core net of 3GPP by wlan network or 3GPP system, not only increased the data traffic load of core net, and multiple business seizes limited Internet resources, possibly can't guarantee the quality of service high to qos requirement.Therefore, when portable terminal accessed EPS by WLAN, adopting effectively to business, shunting was necessary.With reference to Fig. 2, take S2b as example, operator can be according to the feature of business, partial service is transmitted by EPS, path such as Business Stream 2, and other part business (such as: internet business, mobile network's characteristic service etc.) can directly shunt from WLAN, as: the path of Business Stream 1 and Business Stream 3, to reduce the traffic load of 3GPP core net.

Under the trend that the FMC framework degree of depth merges, when 3GPP UE directly carries out service distributing by WLAN, the policy control server of 3GPP network or accounting server still can issue specific strategy control or the charging relevant with portable terminal to portable terminal and make a strategic decision to fixed network, such as: the concrete type of service for certain portable terminal is carried out policy control or charging etc.; The network element of fixed network is received after the charging decision-making of the strategic decision-making of policy control server or accounting server, can be carried out the policy control relevant with concrete UE or the collection of charge information.

In the prior art, at home gateway (Routing Gateway or Residential Gateway, RG) be route pattern and network enabled address (port numbers) translation (Network Address (Port) Translation, NA (P) T) be N: when 1 (N is more than or equal to 1), RG is at authentication protocol (the Extensible Authentication Protocol that carries out based on the expansion of 3GPP, EAP) in the verification process, as the authenticator, can obtain network access Identifier (the Network Access Identifier of user terminal, NAI), such as: international mobile contractor's sign (International Mobile Subscriber Identity, IMSI).Set up NA (P) when T enters oral thermometer at RG, can set up mobile node network access Identifier (Mobile Node NAI, MN NAI) and port numbers set (N equals at 1 o'clock, assignment of port numbers not) and the incidence relation of UE IP address, be called the user terminal identification contingency table, as shown in Figure 3, wherein, port numbers set (N equals at 1 o'clock, not assignment of port numbers) and UE IP address are that RG carries out after NA (P) the T conversion.And, RG also supports by remote authentication dial-in user service (Remote Authentication Dial In User Service, RADIUS) or DHCP (Dynamic Host Configuration Protocol, DHCP) or the message such as PMIP, the user terminal identification contingency table is passed to broadband gateway/broadband remote access servers (Broadband Network Gateway/Broadband Remote Access Server, BNG/BRAS).

When RG was bridge mode, BNG/BRAS as the authenticator, can obtain MN NAI in the EAP verification process of carrying out based on 3GPP.Generally, when BNG/BRAS distributed a public network address as UE IP address for this UE, BNG/BRAS can set up the incidence relation of MN NAI and UE IP address, but did not comprise the port numbers set; And if BNG/BRAS distributes a private net address as UE IP address for this UE, then BNG/BRAS need to support NA (P) T, and this incidence relation then needs to comprise the port numbers set, specifically referring to Fig. 3.For the ease of statement, here to being referred to as UE IP address through the IP address behind NA (P) T.

From top prior art, when BNG/BRAS can be supported in the UE service distributing, carry out the policy control relevant with concrete UE or the collection of charge information, then, with charge information by Certificate Authority and accounting server (Authentication Authorization and Accounting, AAA) report mobile network's accounting server, so that concrete UE is carried out accounting management.

Portable terminal is undertaken in the business of service distributing by fixed network, both comprised that internet was professional, the distinctive application of fixed network is professional, also comprise the applied business that the mobile network disposes near the fixed network position, these applied business can be mobile operator network internal administrations, also can be third party's deployment of signing interworking protocol with mobile operator.The applied business platform can be understood as the function of Application Function network element (Application Function, AF) or uses measuring ability entity (Traffic Detection Function, TDF).

In the prior art, when AF was positioned at the mobile network, AF received when the business of UE is set up request, meeting and strategy and charging regulation function entity (Policy and Charging Rules Function, PCRF) carry out mutual, the decision-making of whether accepting to the PCRF requested service.If AF receives the business that PCRF returns and accepts can transmit the business information of accepting to UE after the business information of indication and acceptance; If what AF received is the refusal indication, then can send the professional information of setting up of refusal to UE.When the user accessed mobile network's AF or TDF, AF or TDF can pass through DRA, select suitable PCRF: for the roaming place access, AF or TDF select visited place PCRF (visited PCRF, vPCRF) by the DRA of roaming place; For the ownership place access, AF or TDF select ownership place PCRF (home PCRF, hPCRF) by the DRA of ownership place.

Above technology relate to the problem how AF or TDF find suitable PCRF, if when disposing a plurality of PCRF among the mobile network, AF or TDF can be based on UE IP address or MN NAI, generally, business request information is not carried MN NAI, therefore, AF or TDF mainly are based on UE IP address.

In addition, when UE adhered to, broadband policy control functional entity (Broadband Policv Control Function, BPCF) can by DRA, be selected suitable PCRF: for the roaming place access, BPCF selects vPCRF by the DRA of roaming place; For the ownership place access, BPCF selects vPCRF by the DRA of roaming place; Then, vPCRF selects hPCRF by the DRA of ownership place.BPCF can find suitable PCRF by IMSI.

Although AF/TDF is different with the foundation that BPCF seeks PCRF,, for same UE, need to select same PCRF.Equally, AF or TDF are arranged in fixed network, and the foundation of BNG/BRAS and AF/TDF searching BPCF also can be different, therefore, also need to select same BPCF.

When UE directly accessed applied business, UE IP address was that RG/BNG/BRAS carries out NA (P) T IP address afterwards, and this address is that fixed network distributes.Here, be illustrated with AF, when AF was deployed in the mobile network, it can admit strategy to mobile network's PCRF requested service.But, if AF searches according to the principle that existing PCRF selects, AF is according to UE IP address, search mobile network's DRA, distribute because this UE IP address is fixed network, in mobile network's DRA, do not dispose PCRF address corresponding to this UE IP address, therefore, can't find policy server address corresponding to this address, specifically can be with reference to figure 4.Be arranged in fixed network and work as AF, because UE IP address may be used for a plurality of UE, but the set of the port numbers of each UE is different, therefore, when BNG/BRAS chooses suitable BPCF according to IMSI, if AF or TDF are by UE IP address choice BPCF, for concrete UE, the BPCF that AF or TDF select is different with the BPCF possibility that BNG/BRAS selects.
