Description

A kind of method and apparatus of transmission route rule
Technical field
The present invention relates to field of communication technology, more particularly to a kind of method and apparatus of transmission route rule.
Background technology
When operator thinks a Wireless LAN（Wireless Local Area Networks, WLAN）Access net When network is credible, it is that believable WLAN accesses network which, which accesses network,（Trusted WLAN Access Network, TWAN）.The logical architecture of TWAN is as shown in Figure 1, include following logic entity：
1, WLAN accesses network（WLAN Access Network, WLAN AN）：By one or more WLAN access points groups At access point terminates user equipment（User Equipment, UE）WLAN Institute of Electrical and Electronics Engineers（Institute Of Electrical and Electronic Engineers, IEEE）802.11 link.
2, credible WLAN access gatewaies（Trusted WLAN Access Gateway, TWAG）With following function：
When TWAN uses transparent single connection pattern（Transparent Single-Connection mode, TSCM）Or Single connection pattern（Single-Connection mode, SCM）Evolved Packet Core is provided to UE（Evolved Packet Core, EPC）When access, TWAG forwards data packet between UE-TWAG point-to-point links and the tunnels S2a of UE；
When TWAN uses multi-connection pattern（Multi-Connection mode, MCM）When providing EPC accesses to UE, TWAG with specific cluster data network（Packet Data Network, PDN）Connect relevant UE-TWAG point-to-point links and User face data is forwarded between the relevant tunnels S2a；Wherein, WLCP signalings are used between UE and TWAG.
3, credible WLAN AAA agencies（Trusted WLAN AAA Proxy, TWAP）：In WLAN AN and 3GPP AAA Server or 3GPP AAA Proxy（Roaming scence）Between transfer authentication, authorization, accounting（Authentication, Authorization and Accounting, AAA）Information.What TWAP storage UE subscription data and UE were used in WLAN AN Binding relationship between MAC Address.When being initially attached to the subscription data of TWAN or UE in UE and changing, TWAP is to TWAG The subscription data of UE is provided.
When UE accesses network by TWAN, above-mentioned three kinds of operation modes workable for UE（TSCM, SCM and MCM）In It is a kind of.Which kind of pattern UE finally uses, and UE and TWAN is needed to negotiate in authentication process.Wherein：
SCM only supports UE to establish a non-seamless WLAN unloading by TWAN in synchronization（Non-seamless WLAN Offload, NSWO）Connection or a PDN connection.In order to establish NSWO or PDN connections, SCM needs to extend expansible certification association View-Authentication and Key Agreement（Extensible Authentication Protocol-Authentication and Key Agreement, EAP-AKA '）Agreement；MCM supports that UE establishes at least one PDN connections simultaneously by TWAN and/or NSWO connects It connects.In MCM, after access authentication procedure terminates, the control protocol used between UE and TWAN is WLAN control protocols（WLAN Control Protocol, WLCP）, the agreement is for triggering PDN establishment of connections or release.
It keeps the IP address of UE and UE to establish when SCM and MCM supports UE to move between 3GPP and TWAN to write from memory with non- Recognize the relevant PDN connections of APN.TSCM does not support UE to send switch prompting, APN and PCO by TWAN, so if using TSCM, the IP address of UE is cannot keep when UE is moved between 3GPP and TWAN, and UE can not establish related to non-default APN PDN connections, UE can not initiate establish to additional PDN connection process.
Routing rule（Routing Rule）Refer to route filter（filter）With routing address or routing access class Incidence relation between type.Wherein, route filter is made of the one group of packet header IP parameter value or range, and IP flows for identification, road It is a routable IP address by address, routing access style is packet data network gateway（Packet Data Network Gateway, PGW）It route the type of access network used in the IP streams of UE（Such as 3GPP accesses or WLAN are accessed）.
A routing rule table being made of a plurality of routing rule, as shown in table 1.When an IP streams can simultaneously with a plurality of road It, can be according to traffic identifier when being matched by the route filter in rule（Flow Identification, FID）Priority determination makes Which routing rule IP streams are route with.
Table 1:Routing rule table；
Internet Protocol flow mobility（IP Flow Mobility, IFOM；Internet Protocol, IP）Technology is ground What is studied carefully is：When UE is connected to same PDN connections by a variety of accesses, IP streams are transmitted and move between different accesses Method.Such as, operator can specify that best effort IP streams（The IP streams done one's best）By WLAN shunt, and with spy Determine service quality（Quality of Service, QoS）It is required that IP stream by evolved universal mobile communication system land it is wireless Access net（Evolved UMTS Terrestrial Radio Access Network, E-UTRAN；Universal Mobile Telecommunications System, UMTS）Access is transmitted.Third generation partner program（The 3rd Generation Partnership, 3GPP）Business and system aspects（Service and System Aspect, SA2）From Version 10（Release10, R10）Start to study IFOM and standardized, completes and assisted based on terminal mobility management The standardization of the IFOM of view, and in R11（R12 is not studied）IFOM based on network mobility management agreement tentatively grind Study carefully.
One, the IFOM schemes based on terminal mobility management agreement.
TS23.261 is defined based on double stack hierarchical mobile IP sheets 6（Dual Stack Mobile IP version6, DSMIPv6）Agreement（S2c interfaces）IFOM methods, when UE by 3GPP access and non-3GPP access be connected to same PDN connections, and when decision progress IP stream movements, will pass through and bind update（Binding Update, BU）Message indicates to move to PGW Dynamic IP stream informations, specifically：UE is updated by binding（Binding Update, BU）Message indicates newer to PGW routing rule；PGW is changed by Internet Protocol connected reference network session and is asked（IP-CAN session modification request；IP Connectivity Access Network, IP-CAN）Message, by what is received Routing rule are supplied to policy control and charging rule functions（Policy Control and Charging Rules Function, PCRF）Entity；PCRF preserves the routing address and business data flow received（Service Data Flow, SDF）Mapping, and to PCRF return IP-CAN session modifications response（IP-CAN session modification response）Message；PGW is by binding response（Binding Acknowledgement, BA）Message connects to UE instruction networks The routing rule received.
Two, the IFOM schemes based on network mobility management agreement（NB-IFOM）.
TR23.861 is defined based on proxy-mobile IP version 6（Proxy Mobile IP version6, PMIPv6） （S2a, S2b interface）/ general packet wireless service tunnel protocol（GPRS Tunneling Protocol, GTP；General Packet Radio Service, GPRS）（S2b interfaces）The IFOM methods of agreement, the basic thought of these methods be based on The IFOM methods of DSMIPv6 are consistent, are all that UE indicates newer routing rule to PGW, difference lies in used transmission Agreement is different, and details are not described herein again.
UE-initiated NB-IFOM defined in 3GPP standards, i.e., the NB-IFOM processes initiated by UE, when UE connections Network is accessed to 3GPP（Such as E-UTRAN）When accessing network with WLAN, UE can be accessed by 3GPP and WLAN is accessed to network Send routing rule.It also proposed Network-initiated NB-IFOM, i.e., the NB-IFOM mistakes initiated by network at present Journey.But access network when UE is connected to 3GPP（Such as E-UTRAN）When with TWAN, it is connected to especially by single connection pattern When TWAN, how network by TWAN issues routing rule to UE, and there are no solutions.
