Description

The method and apparatus of access mobile communication system

Technical field

The present invention relates to moving communicating field, particularly, the present invention relates to the method and apparatus of access mobile communication system.

Background technology

Present mobile communication more and more trends towards providing the multimedia service of high rate data transmission, and 3G technology has become the main research field of present mobile communication.3GPP(3rd Generation Partnership Project, third generation partner program) be devoted to the Evolution by LTE(Long Term, Long Term Evolution) system is as the evolution of 3G system.

Existing LTE network is for carrying the IP operation stream of LTE UE, and its network reference model, referring to Fig. 2, relates generally to network element and comprises:

1) LTE user terminal (LTE UE): the mobile device that can carry out wireless signal transmitting-receiving, Base-Band Processing and higher layer applications operation, be responsible for and base-station connected Radio Resource, the IP data packet head compression/de-compression obtained, customer traffic encrypt/decrypt, uplink service stream QoS guarantees and ip packet filter;

2) Universal Terrestrial Radio Access Network of evolution (E-UTRAN): be responsible for RRM, the compression of IP data packet head and user data stream encryption, the scheduling of beep-page message and the measurement of transmission, movement and scheduling etc.;

3) Mobility Management Entity (MME): the distribution of control signal, paging and control information between responsible processing user terminal and core net, Bearer Control, mobile management etc.;

4) gateway (SGW): be responsible for bag route and forwarding, downlink data buffer memory, as mobility control anchor point when mobile terminal switches simultaneously;

5) packet data network gateway (PGW): IP address assignment, QoS assurance, charging and the ip packet filter of being responsible for user terminal;

6) home subscriber server (HSS): comprise user profile, carry out user's authentication and authentication, and the information of relevant user's physical location can be provided;

7) strategy and functional server of charging rules (PCRF): comprise policy control decision-making and the control of the charging based on stream function.

The QoS bearing link of existing LTE system is based on IP bag, to set up completely, and LTE user can select to be linked into different APN(Access Point Name, APN according to type of service).Go in the passage of same APN, LTE network can be set up according to qos requirement the bearer path of a plurality of different QoS types.Business Stream is by TFT(Traffic Flow Template, traffic flow template) rule classifies, and be mapped in corresponding carrying, wherein uplink service stream completes the mapping of carrying at UE, and downstream service flow completes carrying mapping at PGW.Current TFT classifies according to the five-tuple information in IP message, specifically with reference to figure 3.

The network structure of existing broadband access network is referring to Fig. 4, and its mainly access feature is

1) protocol stack XoE(is as IPoE, PPPoE etc.);

Embodiment

Describe embodiments of the invention below in detail, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has the element of identical or similar functions from start to finish.Below by the embodiment being described with reference to the drawings, be exemplary, only for explaining the present invention, and can not be interpreted as limitation of the present invention.

In order to realize the present invention's object, realize non-3GPP user's flow at the transparent transmission of LTE network, and effectively manage non-3GPP user, the present invention proposes by the related protocol support of 3GPP and realize non-3GPP user by the business of 3GPP network insertion.

The 3GPP UE that is connected with non-3GPP subscriber equipment initiates to adhere to request, adheres to and in request, comprises specific APN value;

3GPP UE and PGW set up bearing link, and the Ethernet packet of non-3GPP subscriber equipment is realized to the transfer of data of up-downgoing via bearing link.

Particularly, the transfer of data that the Ethernet packet of non-3GPP subscriber equipment is realized to up-downgoing through bearing link comprises:

The Ethernet packet of up non-3GPP subscriber equipment is transmitted to non-3GPP APN by the link between 3GPP UE and PGW, and non-3GPP APN is determined by described specific APN value;

Or by the Ethernet packet decapsulation of descending non-3GPP subscriber equipment by sent to the subscriber equipment of non-3GPP by 3GPP UE.

In the present invention, Ethernet packet includes but not limited to the packet of the LAN protocol collection of IEEE802.3 standard definition, conventionally also the packet in the communication protocol second layer is called to MAC packet.For ease of understanding the present invention, in the present invention, the difference of Ethernet packet and MAC packet is not further distinguished in some areas, by MAC packet, the present invention is given an example.For example the terminal of non-3GPP may be diversified.Except WiFi, bluetooth, the sensor even other system such as CDMA, FEMTO all likely utilizes LTE transmitted data on network, the data of now transmitting in LTE network may not be the Ethernet packets of 802.3 standard definitions, may be the MAC packets according to the communication protocol definition of different terminals.Therefore the Ethernet bag in the present invention should be understood to Ethernet and includes but not limited to MAC bag.

For realizing such scheme, need to realize non-3GPP user by the business of 3GPP network insertion by the related protocol support of expansion 3GPP.Particularly:

method and message structure that expansion gateway is selected

A) increase the gateway device (Extend PGW) of local expansion while disposing the access of supporting non-3GPP user, this gateway has been expanded the following function of PGW: the 1) APN to BAS Broadband Access Server place by up MAC package forward; 2) will after the descending MAC packet encapsulation of coming from BAS Broadband Access Server, send to UE.3) TFT for UE carries out charging, specifically referring to Fig. 1.
