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, relate in particular 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 Internet technology and development of wireless communication devices and universal, the user obviously rises to the professional demand of data.In order to satisfy following user's data business demand; 3GPP standardization body is at existing GPRS (General Packet Radio Service; GPRS) EPS (Evolved Packet System has been proposed on the basis of system; The grouping system of evolution) network architecture, thus make the user can enjoy ubiquitous communication service whenever and wherever possible.

On the whole, the EPS system architecture 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, and is as shown in Figure 1.

E-UTRAN adopts LTE (Long Term Evolution; Long Term Evolution)/LTE-A (Long TermEvolution-Advanced; Improved Long Term Evolution) Radio Access Network of technology; It mainly is made up of network entity eNodeB (evolved Node B, evolution base station), realizes radio bearer management, RRM, wireless access control, system broadcasts and functions such as paging, packet route and terminal switching.Through setting up and safeguard eNodeB and UE (User Equipment; Subscriber equipment) air interface LTE-Uu between; And eNodeB and MME (Mobility Management Entity; Mobility Management Entity) connection of S1 interface and between S-GW (Serving Gateway, gateway), the E-UTRAN system is that the terminal provides the wireless access service to core net.

The EPC system is mainly by MME, S-GW, P-GW (Packet Data Network Gateway; Packet data gateway), HSS (Home Subscriber Server; Home subscriber servers) etc. the unit entity constitutes; Aspect functions such as the management of their realization user contracting datas, terminal mobility management, session management, QoS (QualityofService, service quality) assurance, communication security.Under the management control of MME entity; The EPC system is that arrival PDN (Packet Data Network is set up at the terminal with the mode in tunnel; Packet Data Network) data connect, and under the prerequisite that satisfies the QoS demand, realize the data interaction between various device in portable terminal and the PDN network.The PDN network is the computer communication network outside the 3GPP network category, and it can be IMS (IP Multimedia Subsystem, IP multimedia system), the PSS network that operator provides IP operation, also can be other packet data network such as Internet.

Two, the characteristics of data service

Deepen continuously along with what data service was used; The researcher finds; The user through wireless network when use has the service application of big bandwidth, higher data transmission rate demand, aspect mobility the terminal fixed usually or once in a while low speed move, promptly demonstrate nomadic moving characteristic.Specifically; When the user is in the mobile status of fair speed; Like walking, by bus, the user often has no time to be absorbed in the use of Network, therefore the demand requirement to the network bandwidth can decrease; And the continuity of business is had relatively high expectations, promptly require business can not interrupt because the user moves.On the contrary; When the user be in fixing or once in a while low speed move mobile status the time (as being positioned at family room, office etc.); The common hope of user can insert the Internet network fast or carry out data interaction (like recreation, data sharing etc.) with the inner other-end of local network; Therefore the network bandwidth there is higher requirement, but the mobility support aspect of network is not almost required.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 the high amount of traffic amount, during the service application of Hypomobility, the efficient that just seems is on the low side, and cost is too high.Therefore, be necessary to be the feasible indoor wireless access solution of 3GPP cellular network design to this application characteristic.

In order to strengthen the power system capacity under the Hypomobility application scenarioss such as family and medium-sized and small enterprises and to solve the problem of the indoor covering quality difference of 2GHz wireless signal, 3GPP has proposed the notion of HeNB (Home eNodeB, Home eNodeB), and its framework is as shown in Figure 2.HeNB is the integrated function (or function of packet domain equipment) of the Access Network eNodeB of LTE system on function, realizes and being connected of equipment of the core network through the S1 interface.Short to indoor coverage distance, the characteristics that number of users is few, HeNB adopts the transmitting power (generally 23dBm below) suitable with mobile phone to realize wireless coverage 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 that converges a large amount of HeNB chains of command and user plane flow.

Through disposing a radio access node HeNB in family, enterprise or hot zones inside; The EPS system is increasing power system capacity; When solving wireless signal covering quality problem; Utilize the frequency resource of E-UTRAN network special service to be provided, thereby the communication terminal that has nomadic mobility in family, the enterprise network is provided the data, services of higher rate with lower cost to the small number of users in the indoor environment.

In the home base station network framework, the HeNB node is that it has inherited the function of the eNodeB of EPS system node in essence to the extension of the existing 3GPP network architecture.Therefore, for any communication process that carry out at terminal under the covering of HeNB node, HeNB can provide the service of QoS and safety guarantee.But, being limited by such network architecture equally, any communication that carry out at the terminal all need be passed through control and the management of core net node MME and pass through MME and realize the mutual of packet and transmit.Have the high processing complexity like this,, make operator core network bear great burden even if the information interaction between several local terminals also will be come signaling and business load to operator's core net Netowrk tape in the same HeNB coverage.

Except solving the communication issue of hot spot region based on 3GPP network itself; Also utilize WLAN (Wireless Local Area Networks; WLAN) technology is set up WLAN in the public frequency range of IMS; Thereby support to have the visit of the terminal of nomadic features of movement to other networks such as Internet, its network architecture is as shown in Figure 3.WLAN AP (WLAN Access Point, WLAN access point) is the access node in the WLAN.Under the coordination of AP, the WLAN terminal STA realizes the intercommunication between same local area network (LAN) inside terminals through the forwarding of AP.When AP had the effective connection to Internet network or other networks, corresponding network can be inserted through AP in the terminal.

Dispose the method for WLANAP establishment WLAN at family, enterprise or hot zones and set up local connecting system for the terminal effectively, thereby allow the terminal also to realize visit in the inner information interaction that realizes of consolidated network external network with comparatively direct mode.Yet wlan system just not have too much to consider user's Qos demand at the beginning of design, carrier-class QoS guarantee can not be provided as the 3GPP network and the service of " best endeavors payment " only can be provided.In addition; The employed IMS of WLAN technology (IndustrialScientific Medical; Industry, science, medical treatment) working frequency range also makes its interference that receives other system (like bluetooth, ZigBee etc.) easily, and its available resources are restricted to a great extent.
