Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
In LTE system, when business occurs user, such as, when surfing the Net, the network equipment is bound to as this user distributes certain resource for it, and this resource is presented as " tunnel, user face ".Will distribute two tunnels in communication process, one is uplink tunnel, and the data of UE (UserEquipment, subscriber equipment) are sent to outer net by this uplink tunnel; Another is downlink tunnel, and the data of outer net send to UE by this downlink tunnel.In communication process, these two tunnels only can allow this user use, until sign off.Afterwards, tunnel just may be assigned to other users, therefore utilizes any one in these two tunnels, just can in communication time period unique identification UE.
Tunnel, user face can identify by two parameters: IP address of equipment and TEID (TunnelEndpointIdentifier, Tunnel End Point Identifier).Wherein IP address of equipment refers to the IP address of eNodeB or the IP address of SGW in the present invention; TEID is the integer of 4 bytes, is used for mark tunnel, unique at this device interior.After the upstream data of UE arrives eNodeB, data are issued SGW by the tunnel identified by the TEID of SGWIP and SGW side by eNodeB; Otherwise after the downlink data of outer net arrives SGW, data are issued eNodeB by the tunnel identified by the TEID of eNodeBIP and eNodeB side by SGW, and then send to UE by eNodeB.
As seen from the above description, in the present invention, eNodeB equipment and SGW equipment must know the tunnel that the other side distributes, and just can know that user data where sends, otherwise business cannot be carried out.But, although tunnel is distributed by eNodeB and SGW, but data (such as Internet data) can only be transmitted between these two equipment, signaling message can not be transmitted, in other words tunnel information cannot directly transmit between the two devices, transfer must be carried out by MME equipment, therefore need to adopt S1-MME interface and S11 interface.
