Description

A kind of Long Term Evolution local area network (LAN) LTE-LAN system and access device and terminal

Technical field

The present invention relates to wireless communication technology field, particularly relate to a kind of Long Term Evolution local area network (LAN) LTE-LAN system and access device and terminal.

Background technology

One, 3GPP (The 3rd Generation Partnership Project, the third generation partner program) network architecture

In recent years, along with the development of Internet technology and wireless communication technology is with universal, the demand of user to data service obviously rises.In order to the data traffic requirement of future customer can be met, 3GPP standardization group is woven in existing GPRS (General Packet Radio Service, GPRS) system basis on propose EPS (Evolved Packet System, the grouping system of evolution) network architecture, thus enable user enjoy ubiquitous communication service whenever and wherever possible.

On the whole, EPS framework can be divided into Radio Access Network E-UTRAN (EvolvedUTRAN, the UTRAN of evolution) and core network EPC (Evolved Packet Core, Evolved Packet Core) two parts, as shown in Figure 1.

E-UTRAN adopts LTE (Long Term Evolution, Long Term Evolution)/LTE-A (Long TermEvolution-Advanced, the Long Term Evolution improved) Radio Access Network of technology, it is primarily of network entity eNodeB (evolved Node B, evolution base station) form, realize the functions such as radio bearer management, RRM, wireless access control, system broadcasts and paging, packet route and terminal switch.By setting up and safeguarding eNodeB and UE (User Equipment, subscriber equipment) between air interface LTE-Uu, and eNodeB and MME (Mobility Management Entity, Mobility Management Entity) and S-GW (Serving Gateway, gateway) between the connection of S1 interface, E-UTRAN system is the wireless access service that terminal is provided to core net.

EPC system is primarily of MME, S-GW, P-GW (Packet Data Network Gateway, packet data gateway), HSS (Home Subscriber Server, home subscriber servers) etc. element entity form, they realize the aspect function such as management, terminal mobility management, session management, QoS (QualityofService, service quality) guarantee, communication security of user contracting data.Under the management of MME entity controls, EPC system to be set up for terminal in the mode in tunnel and is arrived PDN (Packet Data Network, Packet Data Network) data cube computation, under the prerequisite meeting QoS demand, realize the data interaction of various equipment room in mobile terminal and PDN network.PDN network is the computer communication network outside 3GPP network category, it can be IMS (the IP Multimedia Subsystem that operator provides IP operation, IP multimedia system), PSS network, also can be other packet data network such as Internet.

Two, the feature of data service

Along with deepening continuously of data service application, researcher finds, user is by wireless network when using the service application having compared with large bandwidth, higher data transmission rate demand, and in mobility, terminal maintains static or low speed moves once in a while usually, namely presents nomadic moving characteristic.Specifically, when user is in the mobile status of fair speed, as walking, by bus, user often has no time to be absorbed in the use of Network, therefore can decrease to the demand requirement of the network bandwidth, and require higher to the continuity of business, namely require that business can not be interrupted because user moves.On the contrary, when user is in the mobile status of fixing or low speed movement once in a while (as being positioned at family room, office etc.), user usually wishes to access fast Internet network or carries out data interaction (as played, data sharing etc.) with the other-end of local network inside, therefore higher requirement is had to the network bandwidth, but the mobility support aspect almost not requirement to network.This demand seems particularly evident in some focus occasion, airport lounge like flying, library, coffee shop etc.

Like this, tradition is towards the 3GPP cellular network of high-speed mobile, seamless switching Demand Design, and in the face of high amount of traffic amount, during the service application of Hypomobility, just seeming, efficiency is on the low side, high cost.Therefore, be necessary for this application characteristic to be that 3GPP cellular network designs feasible indoor wireless access solution.

The problem of 2GHz wireless signal indoor covering quality difference is solved in order to the power system capacity that strengthens under the Hypomobility such as family and medium-sized and small enterprises application scenarios, 3GPP proposes HeNB (Home eNodeB, Home eNodeB) concept, its framework is as shown in Figure 2.HeNB is functionally integrated with the function (or function of packet domain equipment) of LTE system Access Network eNodeB, by the connection of S1 Interface realization and equipment of the core network.For in-door covering apart from short, the feature that number of users is few, the wireless coverage that HeNB adopts the transmitting power (generally at 23dBm below) suitable with mobile phone to realize among a small circle usually.Femto gateway HeNBGW is the optional network equipment.For Home eNodeB HeNB, it is rendered as MME and S-GW.For core network element entity MME and S-GW, it is rendered as eNodeB, plays the function converging a large amount of HeNB chain of command and user's surface current amount.

By at family, enterprise or hot zones On-premise radio access node HeNB, EPS is in increase power system capacity, while solving wireless signal covering quality problem, utilize the frequency resource of E-UTRAN network to provide special service to a small amount of user in indoor environment, thus the communication terminal in family, enterprise network with nomadic mobility is provided to the data, services of higher rate with lower cost.

In home base station network framework, HeNB node is the extension to the existing 3GPP network architecture, and it inherits the function of EPS eNodeB node in essence.Therefore, for any communication process that terminal under HeNB coverage is carried out, HeNB can provide the service of QoS and safety guarantee.But be limited by such network architecture equally, any communication that terminal is carried out all needs through the control of core net node MME and management and is realized the mutual of packet by MME and forwarded.There is higher process complexity like this, even if the information interaction in same HeNB coverage between several local terminal also will come signaling and business load to Operator Core Network Netowrk tape, make operator core network subject great burden.

Except solving except the communication issue of hot spot region based on 3GPP network itself, also utilize WLAN (Wireless Local Area Networks, WLAN) technology IMS public frequency band set up WLAN (wireless local area network), thus support that the terminal with nomadic features of movement is to the access of other networks such as Internet, its network architecture is as shown in Figure 3.WLAN AP (WLAN Access Point, insertion point of radio local network) is the access node in WLAN.Under the coordination of AP, WLAN terminal STA realizes the intercommunication between same local area network (LAN) inside terminals by the forwarding of AP.When AP has the effective connection to Internet network or other networks, terminal can access corresponding network by AP.

Dispose the method for WLANAP establishment WLAN (wireless local area network) effectively for terminal establishes local connecting system at family, enterprise or hot zones, thus allow terminal to realize information interaction and the access of realization to external network in comparatively direct mode in consolidated network inside.But wlan system does not just too much consider the Qos demand of user at the beginning of design, carrier-class QoS can not be provided as 3GPP network to ensure and only can provide the service of " best endeavors payment ".In addition, IMS (the IndustrialScientific Medical that WLAN technology uses, industry, science, medical treatment) working frequency range also makes it easily be subject to the interference of other system (as bluetooth, ZigBee etc.), and its available resources are restricted to a great extent.
