Description

A kind of method and apparatus realizing the address intercommunication of user face

Technical field

The present invention relates to wireless communication field, espespecially a kind of method and apparatus realizing the address intercommunication of user face.

Background technology

Along with the continuous evolution of wireless communication technology and standard, mobile Packet Service obtains huge development, and the data throughput capabilities of unit/terminal is constantly promoting.With Long Term Evolution (LTE, LongTermEvolution) system is example, the data that can support descending maximum rate 100 Gigabits per second (Mbps) in 20,000,000 (M) bandwidth are transmitted, in LTE (LTEAdvanced) system of follow-up enhancing, the transfer rate of data will promote further, it might even be possible to reaches 1 gigabits per second (Gbps).

The growth of terminal data portfolio expansion type, make existing Internet resources gradually unable to do what one wishes, particularly in a new generation communication technology (such as 3G, Long Term Evolution (LTE, when LongTermEvolved)) also cannot extensively arrange net, the thing followed is user rate and traffic demand cannot meet, the variation of Consumer's Experience.How preventing and changing this situation is the problem that operator must take into, and needs to accelerate popularization and the network design of new technique on the one hand；On the other hand, it is desirable to be able to by existing network and technology are strengthened, to reach the purpose of fast lifting network performance.Well-known, at third generation partner program (3GPP, The3rdGenerationPartnershipProject) outside the radio network technique provided, current commonly used WLAN (WLAN, WirelessLocalAreaNetwork), the WLAN being based especially on Institute of Electrical and Electronics Engineers (IEEE, InstituteofElectricalandElectronicsEngineers) 802.11 standard is widely used in focus access covering in family, enterprise or even the Internet.The technical specification wherein proposed by WiFi alliance (Wi-FiAlliance) is most widely used, therefore in reality, WiFi network often follows the wlan network based on IEEE802.11 standard to be equivalent to, when do not cause obscure, be hereinafter also adopted by WiFi module to describe the wireless receiving and dispatching and processing module supporting WLAN in network node.

Under this premise, some operators and company have been proposed that merges WLAN with existing 3GPP network, it is achieved joint transmission, to reach load shunting and to improve the purpose of network performance.3GPPSA2 has passed through access network discovery and has selected functional unit (ANDSF, AccessNetworkDiscoverySupportFunctions) scheme, it is provided that a kind of is the pattern that terminal selects target access network according to carrier policy.

3GPPR10 defines ANDSF standard, and ANDSF realizes Intelligent network-selecting as accessing anchor point, is worked in coordination with the mutual of terminal by network, it is achieved effective shunting of network insertion, meets the operation direction of following multi-network cooperative.The information such as ANDSF load Network Based, terminal capability, user's signing situation are generated strategy, and help terminal use to select the network formats of best access, it is achieved the collaborative operation of plurality of access modes.ANDSF both can individually dispose, it is possible to closes with other network element and sets.At present, industry Main Viewpoints thinks that ANDSF can be deployed in scheme on programmable computer controller (PCC, ProgrammableComputerController) equipment.

ANDSF is WLAN interoperability (interworking) scheme based on core net, do not consider the impact on Access Network, additionally due to ANDSF is the scheme of a relative quiescent, situation about can not very well network load and channel quality dynamically be changed adapts to, and has therefore also carried out WLANinterworking discussion in 3GPP Access Network group.In the wireless interoperability of R12WLAN/3GPP, the mechanism of the rule and triggering that perform WLAN shunt is introduced into.

But, core net mechanism and the auxiliary information mechanism from wireless network can not be supplied to network side applied load in real time and channel condition thus merging use Radio Resource.It addition, the data from same bearer can not service on 3GPP and WLAN link simultaneously.Therefore the demand of WLAN and 3GPP system integrating is proposed again RAN65 plenary session.

Compare the WLAN shunt scheme depending on strategy and triggering at present after deliberation, resident Access Network (RAN, ResidentialAccessNetwork) WLAN and the 3GPP system integrating of level polymerization, it is called for short WLAN and 3GPP network close coupling, it is similar to carrier aggregation and dual link, control and the utilization of resource in dual link better are provided for overall system.Compacting into and being polymerized the Radio Resource allowing more combined dispatching WLAN and 3GPP network in real time in radio layer, therefore improves QoS of customer (QoS, QualityofService) and entire system capacity.By better managing the Radio Resource between user, the collective throughput of all users can be increased and whole system capacity is provided.Based under Real-time Channel condition and system service condition, each link scheduling determines to accomplish the level of each bag.User face is anchored on reliable LTE network, it is possible to improve performance by returning back to LTE network.

WLAN and 3GPP network close coupling can apply to the scene (enode b (eNB that cooperates together, EvolvedNodeB) with access point (AP, AccessPoint) complete the integrated operation of RAN layer by internal interface between and be integrated physically, it is essentially similar to 3GPP carrier aggregation, this scene is generally small-cell) and the non-scene that cooperates together (completing the integrated operation of RAN layer by external interface between eNB and AP, be essentially similar to dual link).Fig. 1 (a) for being applied to the schematic diagram of WLAN and 3GPP integrated base stations website with ground collaboration method, Fig. 1 (b) is for non-same ground synergistic application in the schematic diagram of desirable loop-coupled WLAN and 3GPP network, and Fig. 2 is that the scheme of cooperating is applied to the scene schematic diagram of small-cell layout together.

The tightly coupled WLAN shunt scheme of WLAN and 3GPP network has four kinds at present: simplify framework PDCP (PDCP, PacketDataConvergenceProtocol) layer shunting, the PDCP layer shunting of dual link framework, wireless spread-spectrum technology (RLC, RadioLinkControl) layer shunting, media interviews control the shunting of (MAC, MediaAccessControl) layer.

Transmission control protocol (TCP, TransmissionControlProtocol) and UDP (UDP, UserDatagramProtocol) agreement belong to transport layer protocol.Wherein TCP provides the reliable data transmission under Internet protocol (IP, internetprotocol) environment, and the service that it provides includes data stream, reliability, effectively flows control, full-duplex operation and multiplexing.By sending towards connection, end-to-end and reliable packet.UDP is mainly used in the transmission not requiring order of packets to arrive, and the inspection of packet transmission sequence is completed by application layer with sequence, it is provided that the simple unreliable information towards affairs transmits service.Udp protocol and Transmission Control Protocol all use the application that port numbers is different to retain its respective data transmission channel.UDP and TCP is positioned on IP.Application program accesses UDP layer and then uses IP layer to transmit datagram.The header of IP layer specifies source host and destination host address, and the header of UDP layer and TCP layer specifies the source port on main frame and destination interface.

The tightly coupled WLAN shunt framework of WLAN and 3GPP network is only defined by such scheme, but address, user face (such as IP address and/or udp port) the configuration process of close-coupled network system is not discussed.Consider close-coupled network side carry out by comprise address, terminal use face data distribution to WLAN side, it is to be appreciated that terminal is in the address, user face of wlan network, otherwise 3GPP network side cannot encapsulate the customer traffic using wlan network to WLAN side, same end side is it is to be appreciated that address, 3GPP user face, otherwise end side cannot encapsulate the customer traffic using wlan network to WLAN side, and namely WLAN and 3GPP network close coupling function cannot realize.
