Description

A kind of realization device of mobile network's flattening, method and system

Technical field

The present invention relates to mobile communication technology field more particularly to a kind of realization devices of mobile network's flattening, method And system.

Background technique

It is marked at 3G (Third Generation) Moblie standardization body (3rd Generation Partnership Project, 3GPP) In the quasi- version R8 stage, a kind of completely new evolvement network is developed, system architecture is as shown in Figure 1, comprising: the general land of evolution Ground wireless access network (Evolved Universal Terrestrial Radio Access Network, E-UTRAN), it is mobile Property management entity (Mobility Management Entity, MME), gateway (Serving Gateway, S-GW), point Group data network gateway (Packet Data Network Gateway, P-GW) and home subscriber server (Home Subscriber Server, HSS), wherein

E-UTRAN, for realizing all wireless related functions with evolvement network；

MME is responsible for the mobile management of control plane, including user context information and moving condition management, distributing user Temporary identifications (Temporary Mobile Subscriber Identity, TMSI) etc.；

S-GW is that 3GPP accesses internetwork forwarding surface anchor point, terminates the interface of E-TURAN；

P-GW is forwarding surface anchor point and external packet data net between 3GPP access network and non-3GPP access network The interface of network (Packet Data Network, PDN)；

HSS is used for storing user subscription information.

The network element of MME, S-GW, P-GW and HSS usually as core net.

As shown in fig.2, in the system architecture based on above-mentioned evolvement network, UE access Evolved Packet Core (Evolved Packet Core, EPC), and as follows with process that outer data network establishes connection:

S201, UE initiate network attachment process；

After S202, evolution node B (Evolved Node B, eNB) receive the message, selects MME and forward the message to MMF；

S203, MME authenticate and authorize the UE, and after authorization passes through, MME selects gateway, including S-GW and P-GW, to S- GW sends creation conversation request message；

It is omitted here the interactive process with HSS.

After S204, S-GW receive the creation conversation request message, the message is forwarded to P-GW, wherein the message contains S-GW is downlink tunnel mark and the user face address of UE distribution；

After S205, P-GW receive the creation conversation request message, user context information is created for the UE, distributes internet The address agreement (Internet Protocol, IP), and uplink tunnel mark is distributed for the UE, return to creation conversational response message To S-GW；

After S206, S-GW receive the creation conversational response message, the GPRS Tunnel Protocol between S-GW and P-GW is established (GPRS Tunnelling Protocol, GTP) forwarding surface tunnel (GTP User Plane, GTP-U) simultaneously distributes the upper of S-GW Row Tunnel Identifier returns to the creation conversational response message to MME；

S207, MME initiate initial context to eNB and establish request message, and the message is in addition to the uplink distributed comprising S-GW Tunnel Identifier, the parameter (such as IP address) for being sent to UE also include other information outside, as the Security Context Information of UE (is used Wireless transmission encryption between eNB and UE), roaming limitation list (being moved between which eNB for limiting UE) of UE etc.；

Radio bearer is established between S208, eNB and UE, there is one-to-one correspondence in the tunnel GTP-U that radio bearer and gateway are established Relationship；

S209, eNB return to initial context to MME and establish response message, which includes the downlink tunnel mark of eNB distribution Know；

S210, MME send modification bearer messages to S-GW, which includes the downlink tunnel mark of eNB distribution, so far S- GW establishes the tunnel GTP-U between S-GW and eNB, forms from eNB to S-GW to the end-to-end tunnel between P-GW.

After UE access EPC network, specific user face message forwarding process it is as follows: when P-GW from external network (such as Internet after the downlink message for) receiving UE, first according to the purpose IP address in message, determine which UE the message is sent to, Then IP packet encapsulation GTPU protocol header is sent to S-GW, which contains the IP address of S-GW, UDP port number And the downlink tunnel mark of S-GW distribution.After S-GW receives the message from corresponding downlink tunnel, according between tunnel ID Incidence relation modifies the Tunnel Identifier and destination address of GTPU protocol header, then sends GTPU message to eNB.ENB receives message Afterwards, UE is sent to according to which radio bearer is downlink tunnel mark determine from.

In the upstream direction, after eNB receives the message of UE transmission, according to the corresponding relationship of radio bearer and the tunnel GTPU, Uplink tunnel mark is selected, and encapsulates GTPU protocol header, is then sent to S-GW.S-GW receives message from corresponding uplink tunnel Afterwards, according to the incidence relation between tunnel ID, the Tunnel Identifier and destination address of GTPU protocol header are modified, is then sent to P-GW GTPU message.For P-GW after receiving message, message is sent PDN by removal GTPU encapsulation.

As shown in fig.3, due to the mobility of UE, when UE is switched to another eNB from an eNB, basic procedure It is as follows:

Before the handover, end-to-end tunnel is established between UE and P-GW, subsequently through switching prepare and hand-off execution process, UE and target eNB establish wireless connection.

After S301, target eNB and UE establish wireless connection, instruction MME carries out path switching, wherein path switching request Downlink tunnel mark and the user face address of target eNB are carried in message；

S302, MME send modification bearing request message to S-GW, which contains target eNB points The downlink tunnel mark matched；

So far S-GW has been set up the tunnel GTP-U between S-GW and target eNB；

S303, S-GW return to modification bearing response message to MME；

S304, MME return path switching request acknowledgement message give target eNB.

It should be noted that there are also switching of the UE between eNB to further relate to a lot of other switching flows, such as S-GW switching, Other switching flows can refer to the prior art, and which is not described herein again.

Can be seen that in existing mobile network from two processes of above-mentioned S201-S210, S301-S304, UE and PDN it Between by the end-to-end tunnel GTP_U realize connection, and the mobility of UE then need by modify the tunnel GTP-U mark come in fact It is existing.Which results in following two problems:

The first, all data of UE by P-GW, UE and other UE or must be all deployed between P-GW and base station When other service interactions (such as the business being deployed near S-GW), the anchor point by concentration is required, path transmission is not excellent enough Change, causes transmission time long, poor user experience causes the waste of unnecessary network transmission resource.

The second, the tunnel GTP-U is established to need through GTP-C protocol realization, and this agreement is only applicable to EPC network, leads Cause S-GW and P-GW that can only customize realizations, and the gateway of customization is since quantity is few, cost is higher than general interchanger And router, it requires additionally, due to all flows by P-GW, but also P-GW realizes complexity, improves current EPC network Lower deployment cost.
