Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.

Embodiment one

The embodiment of the invention provides a kind of WiFi terminal to insert the method and apparatus in different business territory, this method is applied to ustomer premises access equipment CPE, as Fig. 1,2, shown in 3, Fig. 2 be present embodiment based on network system, wherein the WiFi terminal is attached to WLAN by AP and described CPE communicates by the WiFi mode, described CPE and described base station communicate by the LTE mode, described base station links to each other by EPC a plurality of business domains corresponding with the multiple business difference, like this by the said system framework, make described WiFi terminal by described CPE, described base station, described and described business domains communicates.Provided two kinds of set-up modes of AP (Access Point, WiFi WAP (wireless access point)) and ustomer premises access equipment CPE among the figure, CPE can integrated AP functional module, and as the CPE/AP among Fig. 1, AP also can be two equipment that separate with CPE.Wherein this device of providing of present embodiment is the function that CPE is integrated with AP.

For application system can be to independent counting behind the WiFi terminal access Internet, the WiFi terminal is linked into Internet by the EPS network system need pass through BRAS, and BRAS reports the authentication and accounting server to carry out authentication and accounting to the Internet data service record of WiFi terminal access like this.It is by AC (Access Controller that this CPE and BRAS communicate, the WiFi access controller) an IP address of adopting EPC to distribute for this CPE, the message that communicates by CAPWAP tunnel and described BRAS between this CPE and the AC, described then AC is linked into BRAS, and AC and BRAS also can be physical equipments that integrates certainly.Wherein an IP address be CPE after powering on, CPE finishes the authentication of EPC to CPE according to the normal process of 3GPP, and with after EPC sets up PDN and is connected, EPC is the CPE IP address allocated.

BRAS is this WiFi terminal distribution the 2nd IP address by the system architecture of above-mentioned Fig. 1, specifically as shown in Figure 3, for convenience of explanation, in this process BRAS is divided into AC and BRAS and is divided into two functional modules and illustrates.For WiFi terminal distribution the 2nd IP address process as follows:

At first the WiFi terminal sends DHCP Discovery (Dynamic Host Configuration Protocol, DynamicHost is provided with protocol discovery) broadcasting packet to CPE; CPE encapsulates this message after receiving DHCP Discovery broadcasting packet by CAPWAP tunnel, send to CPE.CPE will be transmitted to AC by the message of CAPWAP encapsulation, the IP address that CPE has used EPC to distribute as CPE in this message.AC carries out the CAPWAP tunnel decapsulation to the message that receives, and is transmitted to BRAS then.BRAS returns DHCP OFFER to AC behind the DHCP Discovery broadcasting packet that receives the transmission of WiFi terminal.AC carries out the CAPWAP tunnel encapsulation to DHCP OFFER message more accordingly, sends to CPE, and CPE carries out sending to the WiFi terminal after the decapsulation to the DHCP OFFER message through the CAPWAP tunnel encapsulation.The WiFi terminal is behind the DHCP OFFER message that receives the BRAS transmission, send DHCP Request broadcasting packet to BRAS, concrete process is with aforementioned to send DHCP Discovery process to BRAS identical, thereby makes BRAS to WiFi terminal distribution the 2nd IP address.

Wherein the data service of WiFi terminal support comprises: in charge professional of IP layer and the business that authenticates in application layer, charge at the IP layer as HSI (High Speed Internet) is professional, operator's recreation, IMS business and IPTV business on one's own account chargeed in application layer.This method comprises:

The upstream data service message that S101, the described WiFi terminal of reception send, described upstream data service message carries the 2nd IP address that Broadband Remote Access Server BRAS distributes to described WiFi terminal.

S102, determine the data service type of the upstream data service that described WiFi terminal is initiated.

After CPE receives the upstream data service message of WiFi terminal transmission, can determine the data service type of the upstream data service that described WiFi terminal is initiated according to the five-tuple information of described upstream data service message.The five-tuple information of upstream data service message can be that CPE is pre-configured, or obtain by the dynamic derivation of the UL-TFT (Uplink Traffic FloW Template, upstream data service flow template) of CPE.

After having determined the upstream data service message that described WiFi terminal is initiated, if the upstream data service that described WiFi terminal is initiated is to authenticate and/or the data service type of chargeing is then carried out S 103 steps at the IP layer; If the upstream data service that the WiFi terminal is initiated is the data service type that authenticates and/or charge in application layer, then carry out the S104 step.

S103, described upstream data service is encapsulated by described CAPWAP tunnel; Send to BRAS after the message transmission of upstream data service that will be by CAPWAP tunnel encapsulation is crossed described EPC, described BRAS sends to the corresponding business territory with the message of described upstream data service.

If the upstream data service that the WiFi terminal is initiated is to authenticate and/or charge at the IP layer, after the upstream data service that CPE sends the WiFi terminal encapsulates by CAPWAP tunnel, the message transmission that CPE will carry described upstream data service is crossed and is sent to AC behind the described EPC and (refer to that EPC does not handle message, EPC is " transparent " with respect to message), AC access BRAS sends to corresponding business with the message of described upstream data service.Like this can be so that application system can authenticate the WiFi terminal separately and/or charge.

S104, described the 2nd IP address transition that will carry the described WiFi terminal that the message of described upstream data service carries are a described IP address of described cpe device; Give the corresponding business territory with the message of the described upstream data service of a described IP address that carries described cpe device by the direct routing forwarding of described EPC.

If the upstream data service that the WiFi terminal is initiated is to authenticate and/or charge in application layer, described the 2nd IP address transition that CPE will carry the described WiFi terminal that the message of described upstream data service carries is that described EPC is an IP address of described CPE module assignment, and the CPE module will be carried upstream data service and be given corresponding business by the EPC routing forwarding then.

The WiFi terminal that the embodiment of the invention provides inserts the method in different business territory, CPE carries out intelligent route according to the different pieces of information business that the WiFi end is initiated, as business to authenticating and/or charge at the IP layer, the message that will carry described upstream data service by described CAPWAP tunnel encapsulates and sends to BRAS after the back transparent transmission is crossed described EPC, and BRAS sends to the corresponding business territory with the message of described upstream data service; For business in application layer authentication and/or charging, described the 2nd IP address transition that then will carry the described WiFi terminal that the message of described upstream data service carries is a described IP address of described cpe device, give the corresponding business territory by the direct routing forwarding of described EPC, the WiFi terminal access business domains that authenticates and/or charge in application layer like this, do not need to pass through BRAS, message between WiFi terminal and business domains does not need the CAPWAP tunnel encapsulation like this, can not increase the header overhead of message, thereby can improve the transmission efficiency of EPS; CPE is by carrying out intelligent route to dissimilar business domains simultaneously, as five-tuple difference for the dissimilar business domains that authenticates in IP layer or application layer and/or charge, make CPE the different pieces of information business of WiFi terminal can be mapped to different EPS carryings, realized the priority scheduling between the different business stream.

Embodiment two

The embodiment of the invention provides a kind of WiFi terminal to insert the method and apparatus in different business territory, this method is applied to LTE ustomer premises access equipment CPE, as Fig. 2,3, shown in 4, Fig. 2 be present embodiment based on network system, wherein the WiFi terminal is attached to WLAN by AP and described CPE communicates by the WiFi mode, described CPE and described base station communicate by the LTE mode, described base station links to each other by EPC a plurality of business domains corresponding with the multiple business difference, like this by the said system framework, make described WiFi terminal by described CPE, described base station, described and described business domains communicates.Provided two kinds of set-up modes of AP (Access Point, WiFi WAP (wireless access point)) and ustomer premises access equipment CPE among the figure, CPE can integrated AP functional module, and as the CPE among Fig. 2, AP also can be two equipment that separate with CPE.Wherein this device of providing of present embodiment is the function that CPE is integrated with AP.

For application system can be to independent counting behind the WiFi terminal access Internet, the WiFi terminal is linked into Internet by the EPS network system need pass through BRAS, and BRAS reports the authentication and accounting server to carry out authentication and accounting to the Internet data service record of WiFi terminal access like this.It is by AC (Access Controller that this CPE and BRAS communicate, the WiFi access controller) an IP address of adopting EPC to distribute for this CPE, between this CPE and the AC by communicating behind the CAPWAP tunnel, described then AC is linked into BRAS, certainly present embodiment be based on AC and BRAS be integrate as physical equipment of BRAS.Wherein an IP address be CPE/AP after powering on, CPE/AP finishes EPC to the authentication of CPE/AP and the foundation of PDN according to the normal process of 3GPP, EPC is the CPE/AP IP address allocated.

BRAS is this WiFi terminal distribution the 2nd IP address by the system architecture of above-mentioned Fig. 2, specifically as shown in Figure 3, for convenience of explanation, in this process BRAS is divided into AC and BRAS and is divided into two functional modules and illustrates.For WiFi terminal distribution the 2nd IP address process as follows:

The Access Control List (ACL) of S201, the pre-configured upstream data service of CPE, or dynamically derive from the Access Control List (ACL) of upstream data service.

The Access Control List (ACL) of upstream data service specifically comprises the five-tuple information of upstream data service, and described five-tuple information has comprised source port, the destination interface of wanting the access service territory and the protocol number of initiating the source address of the terminal of upstream data service, the business domains destination address that will visit, initiating upstream data service.

The Access Control List (ACL) of upstream data service can be by the pre-planning setting, and be configured among the CPE in several ways, comprise: far-end configuration interface TR069/OMA-DM, the DHCP Option of the near-end configuration interface of CPE, CPE, Protocol Configuration Option (PCO) expansion or CAPWAP remote management protocol.The Access Control List (ACL) of upstream data service also can be that the UL-TFT of CPE dynamically derives from, and concrete derivation mode replaces source IP address and source port for adopting asterisk wildcard (*), and it is constant to keep purpose IP address, protocol number and destination interface.Five-tuple information in the Access Control List (ACL) of pre-configured certainly upstream data service also can use asterisk wildcard (*) to replace source address and source port, only pre-configured destination address, protocol number and destination interface.

Further, the Access Control List (ACL) of the upstream data service among the CPE can also be used for different upstream data services are classified and identified precedence information.

S202, CPE receive the upstream data service message that described WiFi terminal sends, and described upstream data service message carries the 2nd IP address that Broadband Remote Access Server BRAS distributes to described WiFi terminal.

S203, CPE determine the type of the upstream data service that described WiFi terminal is initiated according to the described destination address in the five-tuple information of described upstream data service.

After having determined the type of the upstream data service that described WiFi terminal is initiated,, then carry out the S204 step if the upstream data service that described WiFi terminal is initiated is the data service type that authenticates and/or charge at the IP layer; If the upstream data service that the WiFi terminal is initiated is the data service type that authenticates and/or charge in application layer, then carry out the S205 step.

Destination address information in the Access Control List (ACL) of upstream data service can be determined the type of the data service of the business domains that described WiFi terminal will be visited.The data service that the WiFi terminal can be supported comprises having: IMS, IPTV and HSI, operator's self-operated business etc., but be not limited thereto.Usually operator has planned the destination address section in different business territory, the destination address of the data service of initiating according to the WiFi terminal like this, the destination address section of each data service in the Access Control List (ACL) of upstream data service then can be determined the business domains type that the WiFi terminal will be visited.For example, the destination address of IMS business domains is 192.168.0.0-192.168.255.255, if the destination address of the data service that described WiFi terminal will be visited is 192.168.50.23, can determine that so then the data service that described WiFi terminal will be visited is the IMS business domains.Business Stream for not having in described Access Control List (ACL) on the coupling is defaulted as the HSI business.The data service that the WiFi terminal can be supported comprises HSI, IMS, IPTV and operator's self-operated business etc.

Further, after the type of determining the upstream data service that described WiFi terminal is initiated, CPE can also determine the precedence information of the upstream data service that described WiFi terminal is initiated according to the precedence information of pre-configured upstream data service.

S204, CPE encapsulate described upstream data service by described CAPWAP tunnel.

CPE parses the destination address of the business domains that will visit in the upstream data service message of WiFi terminal initiation.If the destination address of the data service that described WiFi terminal will be visited is 1.10.2.3, the Access Control List (ACL) of the corresponding upstream data service of CPE determines that the data service that the WiFi terminal will be visited is the HSI business like this.CPE encapsulates described upstream data service by CAPWAP tunnel like this.

Described the 2nd IP address transition that S205, CPE will carry the described WiFi terminal that the message of described upstream data service carries is a described IP address of described cpe device.

If the destination address of the data service that described WiFi terminal will be visited is 192.168.50.23, CPE determines that then the data service that the WiFi terminal will be visited is the IMS business like this.Because the IMS business is to charge in application layer, CPE is the IP address of CPE self with the 2nd IP address transition of the described WiFi terminal of carrying in this upstream data service message like this.

Is connected if set up many PDN between CPE and the EPC, then CPE is the IP address of corresponding PDN connection with the 2nd IP address transition of the described WiFi terminal of carrying in this upstream data service message.

Upstream data service or the type of upstream data service and the precedence information of described upstream data service that S206, CPE initiate according to described WiFi terminal, the upstream data service that described WiFi terminal is initiated carries out priority scheduling.

Further, in order better to handle a plurality of upstream data services, CPE has also comprised the precedence information of upstream data service in described Access Control List (ACL), CPE provides different priority schedulings according to the corresponding different precedence information of different data service types to different upstream data services like this, concrete can adopt WFQ (Weighted Fair Queuing, Weighted Fair Queuing) congestion management algorithm.

The upstream data service that S207, CPE initiate described WiFi terminal is mapped to corresponding carrying according to the QoS mechanism of EPS.

After upstream data service that CPE initiates described WiFi terminal is mapped to corresponding carrying according to the QoS mechanism of EPS, if the upstream data service that described WiFi terminal is initiated is the data service type that authenticates and/or charge at the IP layer, then carry out the S208 step; If the upstream data service that the WiFi terminal is initiated is the data service type that authenticates and/or charge in application layer, then carry out the S209 step.

For example, after CPE powered on, EPC finished authentication to CPE according to the 3GPP normal process, and set up the PDN connection.The special-purpose EPS carrying that this PDN connects corresponding default EPS carrying and has permanent online demand.

CPE sets up CAPWAP control channel and data channel according to CAPWAP standard and AC simultaneously, is carried on respectively on the EPS dedicated bearer of CPE correspondence, can be on EPS dedicated bearer and default bearer as the carrying of CAPWAP control channel.

Like this if the upstream data service that the WiFi terminal is initiated is to authenticate and/or charge at the IP layer, CPE carries out CAPWAP with the message of described upstream data service and encapsulates like this.CPE is mapped on the corresponding EPS dedicated bearer according to the message of the described upstream data service of QoS mechanism of EPS then.

If the upstream data service that the WiFi terminal is initiated is to authenticate and/or charge in application layer, because the upstream data service that the WiFi terminal is initiated is not linked into the corresponding business territory by BRAS, CPE then is mapped to corresponding carrying according to the QoS mechanism of EPS.As the IMS business, CPE is mapped to this IMS signaling flow in the Non-GBR carrying of QCI=5, and IMS medium voice flow is mapped to the special-purpose GBR carrying of QCI=1, and IMS media video stream can be mapped in the special-purpose GBR carrying of QCI=2.Different like this upstream data services is mapped in the different carryings, thereby EPS can provide different QoS to different upstream data services.

Certainly, above-mentioned carrying mapping is just at the situation of setting up a PDN between CPE and the EPC, if set up under the situation of a plurality of PDN between CPE and the EPC, at each PDN, EPC is that CPE is assigned a plurality of IP address.For example, establish 3 PDN between CPE and the EPC and connect, EPC can be assigned 3 IP addresses for CPE like this.CPE is after the upstream data service message that receives the initiation of WiFi terminal like this, type according to this upstream data service, type as this upstream data service is the IMS business of chargeing in application layer, and CPE has been the IMS service selection article one PDN connects like this.Accordingly, CPE is the IP address of article one PDN of CPE with the 2nd IP address transition of the described WiFi terminal of carrying in this upstream data service message.In article one PDN connection, this upstream data service is carried mapping accordingly according to the QoS mechanism of EPS then.

S208, CPE will be by CAPWAP tunnel encapsulation the message transmission of upstream data service send to BRAS after crossing described EPC, described BRAS sends to the corresponding business territory with the message of described upstream data service.

After the upstream data service that the WiFi terminal is initiated carries mapping, CPE will send to AC by EPC by the upstream data service message of CAPWAP tunnel encapsulation.AC carries out the CAPWAP tunnel decapsulation to this upstream data service message, sends to BRAS then and is linked into the Internet business.BRAS charges to the Business Stream of WiFi terminal access simultaneously.

S209, CPE give the corresponding business territory with the message of the described upstream data service of a described IP address that carries described cpe device by the direct routing forwarding of described EPC.

After the upstream data service that the WiFi terminal is initiated carried mapping, the data service that CPE initiates the WiFi terminal sent to EPC, finally is linked into the IMS territory.

Because CPE will not need in the data service that application layer is chargeed to be linked into the corresponding business territory by BRAS, the data service of initiating for the WiFi terminal does not need to carry out the CAPWAP tunnel encapsulation like this, like this for data service of chargeing such as business such as IMS, VoIP in application layer, to reduce the expense of this data service message greatly, improved the transmission efficiency of EPS; And because CPE/AP is the IP address of CPE with the 2nd IP address transition of WiFi terminal, make EPC can perceive the data service that the WiFi terminal is initiated, thereby can be, thereby can realize the priority scheduling of different business so that the WiFi terminal can be utilized the EPS carrying mapping mechanism among the EPS.

Further, if AP is two equipment that separate with CPE, AP has finished the upstream data service that the WiFi terminal is initiated jointly with CPE and has been linked into different business domains.For example, can adopt Ethernet interface to connect between AP and the CPE, CPE can distribute private network IP address to AP by the DHCP message.In this form, the Access Control List (ACL) of upstream data service can be configured in AP by the local management interface of remote management protocol such as CAPWAP or AP.After AP receives the upstream data service message of WiFi terminal transmission, can determine the type of service of the upstream data service that the WiFi terminal is initiated according to the Access Control List (ACL) of this upstream data service.

If the upstream data service that the WiFi terminal is initiated is the data service of chargeing in application layer, the type of service that AP will carry the upstream data service message of the 2nd IP address of WiFi terminal and the upstream data service that the WiFi terminal is initiated is packaged into message by Ethernet interface and sends to CPE, and the source IP address of this message is the private network IP address that CPE distributes to AP.CPE is after receiving this message, at first the 2nd IP address transition of the WiFi terminal of carrying in the upstream data service message is become the IP address of CPE, the private network IP address transition with the AP in this message becomes the IP address of CPE to send to the corresponding business territory by EPC simultaneously.

If the upstream data service that the WiFi terminal is initiated is the data service of chargeing at the IP layer, the upstream data service message of the 2nd IP address that carries the WiFi terminal that this WiFi terminal is initiated and the type of service of the upstream data service that this WiFi terminal is initiated are packaged into the CAPWAP message by CAPWAP tunnel and send to CPE, and the outer source IP address of this CAPWAP message is the private net address that CPE distributes to AP.CPE converts the outer source IP address of CAPWAP the IP address of CPE to after receiving the CAPWAP message, send to AC after then this message transmission being crossed EPC.AC carries out decapsulation to this CAPWAP message, is transmitted to BRAS then.

Because CPE is the 2nd IP address transition of the WiFi terminal that the upstream data service message in the application layer charging that the WiFi terminal is initiated is carried the IP address of CPE, CPE can be mapped to the data service that this WiFi terminal is initiated in the corresponding EPS carrying according to the IP address of the CPE in this upstream data service message like this; And for the data service of chargeing at the IP layer, because the data service message that the WiFi terminal of CAPWAP encapsulation is initiated carries the 2nd IP address of WiFi terminal, CPE is mapped to the data service of this WiFi terminal initiation in another carrying like this.Thereby can realize the upstream of different business and the priority scheduling between the downstream in EPS carrying aspect, guarantee different QoS (Quality of System, the service quality) grade between the different upstream data service streams.

Further, in the prior art in order to solve to WiFi the terminal separately authentication and/or the problem of chargeing, the WiFi terminal must be linked into application layer charge professional the time need pass through BRAS, thereby can't support the problem that dynamic PCC (Policy Control and Charging, policy control and charging) strategy and static qos policy are disposed.And the business of chargeing in application layer for the WiFi terminal access in the present embodiment, as the IMS business, CPE is the IP address of CPE with the 2nd IP address transition in the upstream data service message of WiFi terminal initiation, the EPC side can perception like this.When IMS passes through PCRF (Policy and Charging Rules Function, the policy charging rule function) to P-GW (Packet Data Network Gateway, grouped data network gateway) triggering special-purpose EPS carries when setting up, P-GW just can be associated with the EPS carrying of CPE, thereby can support dynamic PCC strategy and static qos policy to dispose.

Further, in this enforcement by BRAS to WiFi terminal distribution IP address, the WiFi terminal is linked in the IP layer authentication and/or the business domains of chargeing by BRAS, can realize that application system charges to the WiFi terminal separately; The WiFi terminal is linked into the business domains that application layer is chargeed by EPC simultaneously, by business domains to of the charging of WiFi terminal in application layer, thereby realized that like this application system carries out independent charging to the different business of WiFi terminal access, thereby when having avoided the WiFi terminal to be linked into all different business territories by BRAS, after BRAS charges to all business, also must deduct the expense of the business of also chargeing in application layer.And then reduced the difficulty that BRAS and AAA (Authentication, Authorization, Accounting, authentication, mandate and statistics) server are realized and disposed.

Further, the cpe device that the embodiment of the invention provides can comprise that not only LTE interface unit and base station communicate by Long Term Evolution LTE mode, can also comprise that LTE-A (LTE-Advanced, the follow-up evolution of LTE technology) interface unit and base station communicate by Long Term Evolution LTE-A mode.

A kind of WiFi terminal that the embodiment of the invention provides inserts the method in different business territory, ustomer premises access equipment carries out intelligent route according to the different pieces of information business that the WiFi end is initiated, as business to authenticating and/or charge at the IP layer, the message that will carry described upstream data service by described CAPWAP tunnel encapsulates and sends BRAS after the back transparent transmission is crossed described EPC, and BRAS sends to the corresponding business territory with the message of described upstream data service; For business in application layer authentication and/or charging, described the 2nd IP address transition that then will carry the described WiFi terminal that the message of described upstream data service carries is a described IP address of described cpe device, gives the corresponding business territory by the direct routing forwarding of described EPC.The WiFi terminal access business domains that authenticates and/or charge in application layer like this, do not need to pass through BRAS, message between WiFi terminal and business domains does not need the CAPWAP tunnel encapsulation like this, can not increase the header overhead of message, thereby can improve the transmission efficiency of EPS; Simultaneously by dissimilar business domains is carried out intelligent route, as five-tuple difference for the dissimilar business domains that authenticates in IP layer or application layer and/or charge, make CPE the different pieces of information business of WiFi terminal can be mapped to different EPS carryings, realized the priority scheduling between the different business stream; Further, the difficulty that can reduce BRAS and AAA realization and dispose simultaneously can be so that dynamic PCC strategy of the upstream data service support that the WiFi terminal is initiated and the deployment of static qos policy.

Embodiment three

The embodiment of the invention provides a kind of WiFi of being used for terminal to insert the device 40 in different business territory, shown in Fig. 2,3,5, Fig. 2 be present embodiment based on network system, wherein the WiFi terminal is attached to WLAN by AP and described CPE communicates by the WiFi mode, described CPE and described base station by the LTE mode communicate, described base station links to each other by the corresponding respectively a plurality of business domains of EPC and multiple business, like this by the said system framework, make described WiFi terminal by described CPE, described base station, described and described business domains communicates.Provided two kinds of set-up modes of AP (Access Point, WiFi WAP (wireless access point)) and ustomer premises access equipment CPE among the figure, CPE can integrated AP functional module, and as the CPE among Fig. 2, AP also can be two equipment that separate with CPE.Wherein this device 40 of providing of present embodiment is functions that CPE is integrated with AP.

Wherein can be to independent counting behind the WiFi terminal access Internet for application system, the WiFi terminal is linked into Internet by the EPS network system need pass through BRAS, and BRAS reports the authentication and accounting server to carry out authentication and accounting to the Internet data service record of WiFi terminal access like this.It is by AC (Access Controller that this CPE and BRAS communicate, the WiFi access controller) an IP address of adopting EPC to distribute for this CPE, the message that communicates by CAPWAP tunnel and described BRAS between this CPE and the AC, described then AC is linked into BRAS, and AC and BRAS also can be physical equipments that integrates certainly.Wherein an IP address be CPE after powering on, CPE finishes EPC to the authentication of CPE and the foundation of PDN according to the normal process of 3GPP, EPC is the CPE IP address allocated.

BRAS is this WiFi terminal distribution the 2nd IP address by the system architecture of above-mentioned Fig. 2, specifically as shown in Figure 3, for convenience of explanation, AC and BRAS are as two separate equipment in this process, AC and BRAS can be physical equipments in implementation procedure, have realized the independently function of AC and BRAS equipment simultaneously.For WiFi terminal distribution the 2nd IP address process as follows:

Wherein the data service of WiFi terminal support comprises: in charge professional of IP layer and the business that authenticates in application layer, charge at the IP layer as HSI (High Speed Internet) is professional, operator's recreation, IMS business and IPTV business on one's own account chargeed in application layer.Wherein present embodiment is that to be integrated into same equipment CPE/AP with AP and CPE be that example describes at this device.This CPE comprises: unit 42, determining unit 43, IP layer service processing unit 44, application layer Service Processing Unit 45, processed unit 46, carrying map unit 47 and transmitting element 48 are set up in acquiring unit 41, tunnel.

Described acquiring unit 41 is used for the Access Control List (ACL) of pre-configured upstream data service; Or be used for dynamically deriving from the Access Control List (ACL) of upstream data service; The Access Control List (ACL) of described upstream data service comprises the five-tuple information of upstream data service, and described five-tuple information comprises source address, destination address, source port, destination interface and the protocol number of described upstream data service.

The Access Control List (ACL) of the upstream data service that acquiring unit 41 obtains has comprised the five-tuple information of upstream data service, and described five-tuple information has comprised source port, the destination interface of wanting the access service territory and the protocol number of initiating the source address of the terminal of upstream data service, the business domains destination address that will visit, initiating upstream data service.

The Access Control List (ACL) of upstream data service can be by the pre-planning setting, and by multiple arrangements in CPE, comprise: the near-end configuration interface of CPE, the far-end configuration interface TR069/OMA-DM of CPE, DHCP Option, Protocol Configuration Option (PCO) expansion, the CAPWAP remote management protocol.

The Access Control List (ACL) of upstream data service also can be that the UL-TFT of CPE dynamically derives from, and concrete derivation mode is for to replace source IP address and source port with asterisk wildcard (*), and it is constant to keep purpose IP address, protocol number and destination interface.Certainly the five-tuple information in the Access Control List (ACL) of the pre-configured upstream data service of Access Control List (ACL) acquiring unit 41 also can use asterisk wildcard (*) to replace source address and source port, a configuration purpose address, protocol number and destination interface.

Further, during the five-tuple information of acquiring unit 41 in the Access Control List (ACL) of pre-configured upstream data service, can also dispose the precedence information of different business.

Unit 42 is set up in described tunnel, be used for communicating by described EPC and Broadband Remote Access Server BRAS according to the IP address that described EPC distributes, set up CAPWAP tunnel, WiFi terminal that will be by CAPWAP tunnel encapsulation and describedly send to BRAS at the message that the IP layer authenticates and/or the business domains of chargeing communicates, and by described WiFi terminal and describedly authenticate and/or the described BRAS that makes alternately of the business domains of chargeing is one the 2nd IP address of described WiFi terminal distribution at the IP layer.

BRAS in this enforcement is meant the BRAS that comprises the AC functions of the equipments, sets up CAPWAP tunnel between CPE and the BRAS like this, is used for authenticating and/or the business of chargeing is carried out the CAPWAP tunnel encapsulation at the IP layer that the WiFi terminal is initiated.

Described determining unit 43 is used for determining according to the described destination address of the five-tuple information of described upstream data service the type of the upstream data service that described WiFi terminal is initiated.

The type of the data service of the business domains that the destination address information in the Access Control List (ACL) of upstream data service can be used for determining that described WiFi terminal will be visited.The data service that the WiFi terminal can be supported comprises having: IMS, IPTV and HSI, operator's self-operated business etc., but be not limited thereto.Usually operator has planned the destination address section in different business territory, the destination address of the data service of initiating according to the WiFi terminal like this, the destination address section of each data service in the Access Control List (ACL) of upstream data service, 43 of determining units can be determined the business domains type that the WiFi terminal will be visited.For example, the destination address of IMS business domains is 192.168.0.0-192.168.255.255, if the destination address of the data service that described WiFi terminal will be visited is 192.168.50.23,43 of determining units can determine that the data service that described WiFi terminal will be visited is the IMS business domains like this.Business Stream for not having in the upload control tabulation on the coupling is defaulted as the HSI business.The data service that the WiFi terminal can be supported comprises HSI, IMS, IPTV and operator's self-operated business etc.

Further, after the type of determining the upstream data service that described WiFi terminal is initiated, determining unit 43 can also be determined the precedence information of the upstream data service that described WiFi terminal is initiated according to the precedence information of pre-configured upstream data service.

Described IP layer service processing unit 44, be used for described upstream data service being encapsulated by described CAPWAP tunnel if described determining unit determines that the upstream data service that described WiFi terminal is initiated is the data service type that authenticates and/or charge at the IP layer.

For example, determining unit 43 parses the destination address of the business domains that will visit in the upstream data service message of WiFi terminal initiation.If the destination address of the data service that described WiFi terminal will be visited is 1.10.2.3, the Access Control List (ACL) of determining unit 43 corresponding upstream data services determines that the data service that the WiFi terminal will be visited is the HSI business like this.IP layer service processing unit 44 encapsulates described upstream data service by CAPWAP tunnel like this.

Described application layer Service Processing Unit 45, also be used for if the upstream data service that the WiFi terminal is initiated is the data service type that authenticates and/or charge in application layer, described the 2nd IP address transition of the described WiFi terminal that the message of the described upstream data service of carrying is carried is a described IP address of described cpe device.

If the destination address of the data service that will visit of described WiFi terminal is 192.168.50.23, the data service that will visit of 43 definite WiFi terminals of determining unit is the IMS business like this.Because the IMS business is to charge in application layer, application layer process unit 45 is the IP address of CPE self with the 2nd IP address transition of the described WiFi terminal of carrying in this upstream data service message like this.

Processed unit 46 is used for the type of the upstream data service of initiating according to described WiFi terminal and the precedence information of described upstream data service, and the upstream data service that described WiFi terminal is initiated carries out priority scheduling.

Further, in order better to handle a plurality of upstream data services, the precedence information that has also comprised upstream data service in the upstream data service Access Control List (ACL) that acquiring unit 41 obtains, CPE provides different priority schedulings according to the corresponding different 46 pairs of different upstream data services in precedence information processed unit of different data service types like this, concrete can adopt WFQ (Weighted Fair Queuing, Weighted Fair Queuing) congestion management algorithm.

Carrying map unit 47 is used for upstream data service that described WiFi terminal is initiated and is mapped to corresponding carrying according to the QoS mechanism of EPS.

For example, after CPE/AP powered on, EPC finished authentication to CPE/AP according to the 3GPP normal process, and set up the PDN connection.The special-purpose EPS carrying that this PDN connects corresponding default EPS carrying and has permanent online demand.

The tunnel is set up unit 42 and is set up CAPWAP control channel and data channel according to CAPWAP standard and AC simultaneously, CAPWAP control channel and data channel are carried on respectively on the EPS dedicated bearer of CPE/AP correspondence, can be on EPS dedicated bearer and default bearer as the carrying of CAPWAP control channel.

Like this if the upstream data service that the WiFi terminal is initiated is to authenticate and/or charge at the IP layer, IP layer service processing unit 44 carries out CAPWAP with the message of described upstream data service and encapsulates like this.Carrying map unit 47 then is mapped on the corresponding EPS dedicated bearer according to the message of the described upstream data service of the QoS of EPS mechanism.

If the upstream data service that the WiFi terminal is initiated is to authenticate and/or charge in application layer, because the upstream data service that the WiFi terminal is initiated is not linked into the corresponding business territory by BRAS, 47 QoS mechanism according to EPS of carrying map unit are mapped to corresponding carrying with above-mentioned upstream data service.As the IMS business, carrying map unit 47 is mapped to this IMS signaling flow in the Non-GBR carrying of QCI=5, and IMS medium voice flow is mapped to the special-purpose GBR carrying of QCI=1, and IMS media video stream can be mapped in the special-purpose GBR carrying of QCI=2.Different like this upstream data services is mapped in the different carryings, thereby EPS can provide different QoS to different upstream data services.

Certainly, above-mentioned carrying mapping is just at the situation of setting up a PDN between CPE and the EPC, if set up under the situation of a plurality of PDN between CPE and the EPC, at each PDN, EPC is that CPE is that every PDN connection is assigned an IP address.For example, establish 3 PDN between CPE and the EPC and connect, EPC can be assigned 3 IP addresses for CPE like this.CPE is after the upstream data service message that receives the initiation of WiFi terminal like this, type according to this upstream data service, type as this upstream data service is the IMS business of chargeing in application layer, and CPE has been the IMS service selection article one PDN connects like this.Accordingly, CPE is the IP address of article one PDN of CPE with the 2nd IP address transition of the described WiFi terminal of carrying in this upstream data service message.

Transmitting element 48 sends to BRAS after the message transmission that is used for upstream data service that will be by CAPWAP tunnel encapsulation is crossed described EPC, and described BRAS sends to the corresponding business territory with the message of described upstream data service; Or give the corresponding business territory by the direct routing forwarding of described EPC with the message of the described upstream data service of a described IP address that carries described cpe device.

Because CPE will not be linked into the corresponding business territory by BRAS in the data service that application layer is chargeed, the data service of initiating for the WiFi terminal does not need to carry out the CAPWAP tunnel encapsulation like this, like this for data service of chargeing such as business such as IMS, VoIP in application layer, to reduce the expense of this data service message greatly, improved the transmission efficiency of EPS; And because CPE/AP is the IP address of CPE with the 2nd IP address transition of WiFi terminal, make EPC can perceive the data service that the WiFi terminal is initiated, thereby can be, thereby can realize the priority scheduling of different business so that the WiFi terminal can be utilized the carrying mapping mechanism of EPS.

Further, if AP is two equipment that separate with CPE, two separate equipment of AP and CPE can realize the function of the CPE of above-mentioned integrated AP function.Concrete, can adopt Ethernet interface to connect between AP and the CPE, CPE can distribute private network IP address to AP by the DHCP message.In this form, the Access Control List (ACL) of upstream data service can be carried out Remote configuration by the local management interface of remote management protocol such as CAPWAP or AP in AP.After AP receives the upstream data service message of WiFi terminal transmission, can determine the type of service of the upstream data service that the WiFi terminal is initiated according to the Access Control List (ACL) of this upstream data service.

If the upstream data service that the WiFi terminal is initiated is the data service of chargeing in application layer, the type of service that AP will carry the upstream data service message of the 2nd IP address of WiFi terminal and the upstream data service that the WiFi terminal is initiated is packaged into message by Ethernet interface and sends to CPE, and the source IP address of this message is the private network IP address that CPE distributes to AP.

If the upstream data service that the WiFi terminal is initiated is the data service of chargeing at the IP layer, the upstream data service message of the 2nd IP address that carries the WiFi terminal that this WiFi terminal is initiated and the data service type of the upstream data service that this WiFi terminal is initiated are packaged into the CAPWAP message by CAPWAP tunnel and send to CPE, and the outer source IP address of this CAPWAP message is the private net address that CPE distributes to AP.CPE is after receiving the CAPWAP message, and IP layer service processing unit 44 converts the outer source IP address of CAPWAP the IP address of CPE to, sends to AC after then this message transmission being crossed EPC.AC carries out decapsulation to this CAPWAP message, is transmitted to BRAS then.

Because the application layer process unit 45 of CPE is the 2nd IP address transition of the WiFi terminal that the upstream data service message in the application layer charging that the WiFi terminal is initiated is carried the IP address of CPE, CPE can be mapped to the data service that this WiFi terminal is initiated in the corresponding EPS carrying according to the IP address of the CPE in this upstream data service message like this; And for the data service of chargeing at the IP layer, because the data service message that the WiFi terminal of CAPWAP encapsulation is initiated carries the 2nd IP address of WiFi terminal, IP layer service processing unit 44 is mapped to the data service of this WiFi terminal initiation in another carrying like this.Thereby can realize the upstream of different business and the priority scheduling between the downstream in EPS carrying aspect, guarantee different QoS (Quality of System, the service quality) grade between the different upstream data service streams.

Further, in the prior art in order to solve to WiFi the terminal separately authentication and/or the problem of chargeing, the WiFi terminal must be linked into application layer charge professional the time need pass through BRAS, thereby can't support the problem that dynamic PCC (Policy Control and Charging, policy control and charging) strategy and static qos policy are disposed.And the business of chargeing in application layer for the WiFi terminal access in the present embodiment, as the IMS business, the source address in the upstream data service message that processing unit 44 is initiated the WiFi terminal is converted to the IP address of CPE, and the EPC side can perception like this.When IMS passes through PCRF (Policy and Charging Rules Function, the policy charging rule function) to P-GW (Packet Data Network Gateway, grouped data network gateway) triggering special-purpose EPS carries when setting up, P-GW just can be associated with the EPS carrying of CPE, thereby can support dynamic PCC strategy and static qos policy to dispose.

Further, in this enforcement by BRAS to WiFi terminal distribution the 2nd IP address, the WiFi terminal is linked into the business domains of chargeing at the IP layer by BRAS, can realize that application system charges to the WiFi terminal separately; The WiFi terminal is linked into the business domains that application layer is chargeed by EPC simultaneously, carrying out application layer by business domains in the WiFi terminal charges, thereby realized that like this application system carries out independent charging in advance to the different business of WiFi terminal access, thereby when having avoided the WiFi terminal to be linked into all different business territories by BRAS, after BRAS charges to all business, also must deduct the expense of the business of also chargeing in application layer.And then also reduced the difficulty that BRAS and AAA (Authentication, Authorization, Accounting, authentication, mandate and statistics) server are realized and disposed.

A kind of WiFi terminal that the embodiment of the invention provides inserts the device in different business territory, determine the type of the upstream data service that the WiFi terminal is initiated in determining unit, carry out intelligent route by the different pieces of information business that IP layer service processing unit or application layer Service Processing Unit are initiated the WiFi end, as business to authenticating and/or charge at the IP layer, the message that IP layer service processing unit will carry described upstream data service by described CAPWAP tunnel encapsulates and sends BRAS after the back transparent transmission is crossed described EPC, and BRAS sends to the corresponding business territory with the message of described upstream data service; For business in application layer authentication and/or charging, described the 2nd IP address transition that the application layer Service Processing Unit then will carry the described WiFi terminal that the message of described upstream data service carries is a described IP address of described cpe device, gives the corresponding business territory by the direct routing forwarding of described EPC.The WiFi terminal access business domains that authenticates and/or charge in application layer like this, do not need to pass through BRAS, message between WiFi terminal and business domains does not need the CAPWAP tunnel encapsulation like this, can not increase the header overhead of message, thereby can improve the transmission efficiency of EPS; By dissimilar business domains is carried out intelligent route, the five-tuple difference in different business territory makes CPE the different pieces of information business of WiFi terminal can be mapped to different EPS carryings, has realized the priority scheduling between the different business stream simultaneously.

Further, the difficulty that can reduce BRAS and AAA realization and dispose simultaneously can be so that dynamic PCC strategy of the upstream data service support that the WiFi terminal is initiated and the deployment of static qos policy.

Further, CPE can also realize the scheduling of different priorities is carried out in a plurality of different business territory that the WiFi terminal is initiated by self priority configuration to the different business territory.
