For the ease of the understanding to technical solution of the present invention, it is necessary to first be carried out such as to the principle of the present invention and corresponding term Under guiding explanation.

UE with network by establishing PDU sessions (session) or PDN connect and carries out data transmission.It is follow-up to put it more simply, PDU sessions or PDN connections are all referred to as session or UE sessions.UE can establish different sessions from network, different sessions Data destination node can be different.Different sessions can have the requirement of different business continuances.Such as

Remain business continuity sexual norm：No matter any wireless access technology of UE access or cell should all keep UE Data destination node it is constant.Maintain UE data destination node be to maintain UE business continuance premise.The pattern is also referred to as Business continuity sexual norm one.

Business continuity sexual norm is kept in specified region：When UE keeps the data destination node of UE not in a region Become, the data destination node of UE can be changed after UE has moved out the region.Business continuity sexual norm two optimizes UE and data Path length between destination node, the business for being suitble to business continuance less sensitive.Too long of path can make data transmission delay Load is transmitted in too long or network to increase.The region can be the coverage of data destination node or the son of the coverage Collection.The coverage of data destination node may diminish to a cell.The pattern is also referred to as business continuity sexual norm two

The business continuity sexual norm of multiple data destination nodes：Allow multiple data destination nodes.Within some period, UE There are two sessions or multiple data destination nodes.Such as in the case that UE and the first data destination node do not discharge, allow UE will be identical Session establishment to the second data destination node.After the data of UE are transferred to the second data destination node by network advertisement UE, it can release Put the first data destination node.The pattern is also referred to as business continuity sexual norm three.

For the convenience of description, following full text remains business continuity sexual norm using the expression of business continuity sexual norm one, Business continuity sexual norm two indicates to keep business continuity sexual norm, business continuity sexual norm three to indicate multiple numbers in specified region According to the business continuity sexual norm of destination node.

The above business continuity sexual norm one, two, three, 3GPP may finally name it using other names, but not shadow Ring the main contents of the present invention.Abundant business continuity sexual norm can be applied to two kinds of system architectures of SAE and 5G, as Fig. 1 with Shown in Fig. 2.

UE can support multiple network fragment (slice) or dedicated network, and different network fragments or dedicated network can be with Support different types of service.The different sessions of UE can be established on different network fragments.The data destination node of UE sessions Usually in network fragment.Change network fragment will change data destination node.And data destination node changes, business continuity Property cannot ensure.

And the network fragment that wireless access network may be supported is different.When the ue moves, the net of target radio access network access Network fragment may not be the current network fragment of UE sessions.If changing the network fragment of UE sessions, UE session data destination nodes It can change.

After proposing the above-mentioned UE connection types gently connected, asked need to solve in initiation volume of data transmission process Topic.It is analyzed one by one below：

Problem 1：To the business of UE, destination node or Target cell may allow UE access but not allow the Individual traffic of UE Access.But wireless access network only just knows that the session information of UE, it is not known that the corresponding business of session establishment of UE is.And Business allows the region of access and does not allow the region of access unclear.

Problem 2：When UE is moved under consolidated network system, the operation of different business continuity pattern is different. 1) to the business of business continuity sexual norm one, it should support continuity, such as switching, transfer UE contexts, data forwarding etc..2) UE sessions to business continuity sexual norm two, only support continuity in business continuance region.When UE is moved to business continuity Property region except region, it should trigger data destination node change.Change the data termination of the UE sessions of business continuance two First discharge old data point.To such session, its context is shifted to destination node when UE is switched to destination node or turned The data estimation sent out between UE and old data destination node is nonsensical, it may be considered that the request release before UE switches.3) to industry The UE sessions of continuity of being engaged in pattern three, as UE movements may establish identical UE sessions between multiple data destination nodes, Since session channel does not discharge between UE and old data destination node, UE is forwarded to destination node when UE is switched to destination node Data between old data destination node are also meaningful.After the completion of switching, UE can be initiated and terminated with old data Session release between point.As it can be seen that about switching, transfer UE contexts, data forwarding, release equicontinuity operation, to difference The operation of the UE sessions of business continuity sexual norm is different.But wireless access network node switches the business of not clear UE sessions The region that continuity pattern, business continuance are kept.

Problem 3：When the ue moves, the network fragment that target radio access network access is supported may not be that UE sessions are current Network fragment, it may be considered that UE sessions are mapped to the network fragment of target network support.When change network fragment can cause to count It is changed according to destination node.Business continuity sexual norm one is to change data destination node.So the UE sessions of business model one It should not carry out the mapping or change of network fragment.When target radio access network node is not supported to initiate release business model one The network fragment of UE sessions, source or target radio access network node, which can be initiation and discharge the business, should not also change network point Piece.

Problem 4：When UE is moved between different network systems, interoperate (cutting between such as network system between network system Change or double attachments) require keep UE sessions data destination node.UE sessions to business continuity sexual norm one can be supported It interoperates between network system.UE sessions to business continuity sexual norm two, target network systems most is not in its continuity In hold in range, estimation need not be supported to interoperate between network system.
