Problems solved by technology

However, if the user stays in the network of a certain wireless access technology A for a long time to perform periodic routing area updates, there will be a problem that in another wireless access technology B, the data of the user may be lost User data cleared due to timer expiration
In this way, when the user terminal moves into the wireless access technology B, since there is no requirement to update the routing area, there is no user data in this technology, and the initiated service operation will fail

Embodiment 1

[0119] The SAE and the Pre-SAE each allocate a temporary mobile subscriber identity TMSI to the UE, and the registration operation can be an attach operation or a routing area update operation. Wherein, attaching (ATTACH) to two RATs (RadioAccess Type; wireless access type) is completed in one process, and routing area update (RAU: Routing Area Update) is completed in two RATs in one process.

[0120] The implicit separation and removal function is only enabled in the MME / UPE in one RAT (generally, the network element storing the main data); the implicit separation and removal function is canceled in the MME / UPE in another RAT.

[0121] As shown in Figure 5, the specific process is as follows:

[0122] Step 1, the user terminal UE discovers the access system of the wireless access network A, selects the access system of the wireless access network A, and decides to perform an attach operation or a cross-MME / UPE routing area update operation;

[0123] Step 2, the UE sends an A...

Embodiment 2

[0132] The SAE and the Pre-SAE each allocate a TMSI to the UE, and the registration operation is an attach operation or a periodic update operation. Wherein, the ATTACH to the two RATs is completed in one process; the RAU to the two RATs is completed in one process.

[0133] When the UE performs a periodic routing area update operation in radio access network A or a normal routing area update operation inside the MME / UPE, the MME / UPE of radio access network A detects that the RAT has been changed between this operation and the previous operation. technology, it is necessary to notify the MME / UPE of radio access network B to cancel the implicit detachment and clearing function, and at the same time, the MME / UPE of radio access network A starts the implicit detachment and clearing function.

[0134] As shown in Figure 6, the specific steps are as follows:

[0135] Step 1, the user terminal UE discovers the access system of the wireless access network A, and selects the access s...

Embodiment 3

[0148] The SAE and Pre-SAE each allocate a TMSI to the UE, and the registration operation can be an attach operation or a routing area update operation. Wherein, the ATTACH is completed in two processes to the two RATs; the RAU is completed in two processes in the two RATs. The first ATTACH process or the first RAU process is completed according to normal operation; in the second ATTACH process or the second RAU process, the MME / UPE of the radio access network A needs to notify the MME / UPE of the radio access network B UPE cancels implicit detach and cleanup functions. The notification message may be indicated by an identity request (Identity Request).

[0149] As shown in Figures 7A and 7B, the specific steps are as follows:

[0150] Step 1, the UE discovers the access system of the wireless access network A, selects the access system of the wireless access network A, and decides to perform an attach operation or a cross-MME / UPE routing area update operation;

Abstract

When logging on both evolution network of system architecture (ENSA) and evolution network of non system architecture (ENNSA), user terminal selects to execute adherent operation or operation for updating route zone in ENSA or ENNSA. When user terminal carries out adherent operation or operation for updating route zone in execution network, the mobility management entity (MME) and user face entity (UFE) of the execution network informs not executing adherent operation or operation for updating route zone on MME and UFE. The invention prevents user data from clearing away so as to guarantee correct processing service.

Description

technical field [0001] The invention relates to a 3GPP network system, in particular to a method for synchronizing user data when a mobile terminal simultaneously registers two networks. Background technique [0002] In order to enhance the competitiveness of future networks, 3GPP (3rd Generation Partnership Project) is studying a new evolutionary network architecture, including system architecture evolution (SAE: System Architecture Evolution) and access network Long-Term Evolution (LTE: Long-Term Evolution). [0003] Among them, the evolved access network is called the evolved UMTS Territorial Radio Access Network (E-UTRAN: Evolved UMTS Territorial Radio Access Network), and the evolved packet core network architecture is shown in Figure 1, including the Mobility Management Entity (MME: Mobility Management Entity), User Plane Entity (UPE: User Plane Entity), and User Plane Anchor (InterAS Anchor: Inter Access System Anchor) between different access systems are three logic...
