Problems solved by technology

Obviously, the simultaneous coexistence of IPSec tunnels and MIP tunnels increases the complexity of the system; and, since IPSec and MIP technologies exist at the same time, UE will be assigned up to three communication addresses corresponding to IPSec and MIP technologies during the communication process , which causes a very serious waste of air interface resources and address resources
Furthermore, the existence of MIP technology also requires the UE to support the MIP protocol; however, there are currently a large number of UEs that do not support the MIP protocol, which will cause the UE to fail to communicate normally
In addition, when the UE is handed over, not only the IPSec tunnel but also the MIP tunnel must be updated; this will significantly increase the communication delay caused by the UE handover

Embodiment 1

[0080] Embodiment 1. Communication connection management when UE moves from 3GPP Network to non-3GPP Network:

[0081] Referring to FIG. 8, FIG. 8 is a flow chart of mobility management in a preferred embodiment of the present invention, the process includes the following steps:

[0082] Step 801: When the UE has services in the 3GPP Network, the UE can communicate and interact with the external network through the SAE Anchor; when moving from the 3GPP Network to the non3GPP Network during the communication process, the UE needs to communicate with the non 3GPP GW in the non 3GPP Network Perform the access authentication process.

[0083] Step 802: The non 3GPP GW performs an authentication process for the UE with the HSS / Authentication, Authorization and Accounting Server (AAA Server) according to the UE information obtained during the access authentication process.

[0084] Step 803: Through the IP address allocation process with the non 3GPP GW, the UE obtains an IP addres...

Embodiment 2

[0105] Embodiment 2: Mobility management when UE moves from non-3GPP Network to 3GPP Network:

[0106] Referring to FIG. 11, FIG. 11 is a flow chart of mobility management in another preferred embodiment of the present invention, which includes the following steps:

[0107] Step 1101: When there is business in the non-3GPP Network and moves to the 3GPP Network, the UE needs to apply the existing technology to perform an attach process with the LTE Anchor / SGSN to attach to the 3GPP Network.

[0108] Step 1102: The LTE Anchor / SGSN performs an authentication process for the UE with the HSS / AAA Server according to the UE information obtained during the attach process.

[0109] Step 1103: the UE sends a packet data protocol (PDP) activation request to the LTE Anchor / SGSN.

[0110] Step 1104: upon receiving the PDP activation request from the UE, the LTE Anchor / SGSN sends a PDP creation request to the SAEA Anchor.

[0111] Step 1105: When receiving the PDP creation request from th...

Embodiment 3

[0123] Embodiment 3: Mobility management when UE moves from one non-3GPP Network to another non-3GPP Network:

[0124] Referring to FIG. 14, FIG. 14 is a flow chart of mobility management in another preferred embodiment of the present invention, the process includes the following steps:

[0125] Step 1401: When moving from the Old non 3GPP Network to the New non3GPP Network during the communication process, the UE needs to perform an access authentication process with the New non3GPP GW in the moved New non 3GPP Network.

[0126] Step 1402: The New non 3GPP GW performs the UE authentication process with the HSS / AAA Server according to the UE information obtained during the access authentication process.

[0127] Step 1403: Through an IP address assignment process with the New non 3GPP GW, the UE obtains an IP address supporting communication in the moved New non 3GPP Network, that is, a Local IP address.

[0128] Step 1404: The UE sends an Informational request including the ...

Abstract

The invention discloses a system, device and method for implementing the mobility managing. The key device used in the said method is system architecture evolution anchor (SAE Anchor), wherein the said SAE Anchor is used establishing internet security IPSec tunnel when the UE moves to non 3GPP Network by 3GPP Network. The said UE is used in using a general grouping wireless service tunnel protocol GTP in 3GPP Network or strengthening GTP communication, the IPSec tunnel communication is used in non 3GPP Network. The said device and method can obviously reduce the waste of bare resource and address resource and greatly reduce the communication time delay due to UE switch.

Description

technical field [0001] The present invention relates to the communication field, in particular to a system, device and method for realizing mobility management. Background technique [0002] With the development of communication technology, the Third Generation Partnership Organization (3GPP) is trying to study a wireless evolution network for future communication; the wireless evolution network is mainly composed of evolved radio access network (Evolved RAN) and evolved packet core network (Evolved Packet Core, EPC) composition. [0003] Referring to FIG. 1 , FIG. 1 is a structure diagram of a wireless evolution network in the prior art. In Figure 1, the EPC includes the connected Mobility Management Entity / User Plane Entity (MME / UPE) and the Inter Access System Anchor (IASA) between different access systems; and, the IASA consists of the connected 3GPP Anchor and the system architecture Evolution anchor (SAE Anchor) composition. [0004] MME / UPE is connected to Evolved ...
