Specific implementation mode
To make the object, technical solutions and advantages of the present invention clearer, right below in conjunction with the accompanying drawings and the specific embodiments
The present invention is described in detail.
In LTE system, mobile management entity (Mobile Managenment Entity, MME) executes mobile management
With the function of session management.The mobility status of UE is responsible for and is safeguarded in mobile management, includes whether to be registered to website, with
And connected state, Idle state management etc..And session management is then responsible for PDN establishment of connections, modification and maintenance.
Service request (Service Request) process is the transition between states for Idle state and connected state.When UE is in sky
Not busy state has data, and either signaling sends or when receiving paging message, and UE initiates Service Request processes.In this mistake
Cheng Zhong, network can be that UE establishes signaling connection, including NAS signaling, and S1 interface signalings are connected with RRC signaling.Simultaneously for core
The PDN connections in activated state preserved are netted, MME can also initiate the bearer connection of S1 interfaces and RRC interfaces, by all activated state
PDN connections set up.The loaded state step-out of UE and network side may occur in Idle state, such as the sides UE keep certain
One PDN connections are active, but network side locally deactivates, evolved when establishing empty port load-supporting
Base station (evolved Node B, eNB) is not successfully established all PDN connections etc. due to resource.In this case,
UE connect state of activation to synchronize by receiving the message of empty port load-supporting foundation with the PDN of network side.The rrc layer of UE can be by network
The NAS layers of UE are sent to for the UE PDN link informations established.RRC is the PDN connections that UE establishes empty port load-supporting, the NAS layer meetings of UE
Continue to keep state of activation.RRC is not the PDN connections that UE establishes empty port load-supporting, and the NAS layers of UE locally delete PDN connections.
In 5G systems, mobile management function to ps domain and conversation management functional are detached.It is responsible for mobile management function to ps domain
Entity be access and mobile management function to ps domain (access and mobility management function, AMF), bear
The entity for blaming conversation management functional is SMF.Service Request processes are equally used for UE from Idle state to connected state in 5G
Transition between states.When UE is registered to network in 5G, core net only can be UE services there are one AMF, but for different PDU sessions
Management connection, can select different SMF.Therefore when UE establishes multiple PDU session connections, different PDU sessions can be selected
Different SMF are selected, AMF, which needs to establish with these SMF respectively, to be connected, and relevant message is managed for route conversation.
As shown in Figure 1, since AMF and SMF is detached, and UE has multiple SMF entities to be serviced for it, in order to manage UE and core
NAS connections between net, current conclusion are that NAS connections between UE and core net use N1 interfaces, N1 interfaces by point
Positioned at AMF.Mobile management (MM) NAS message and session management (SM) NAS message of UE and core network are all connect by N1
Port transmission.If it is the relevant NAS messages of MM, then directly by AMF processing.If it is the relevant NAS messages of SM, then AMF
Message is not handled but is directly transparent to SMF, is parsed by SMF.
N2 interfaces are the interfaces for accessing net (AN, such as RAN) between core net, and N2 interfaces also are located at AMF by point.
Transmitted by AMF with the relevant message of mobile management, and with the relevant message of session management, then by the SMF processing such as AMF transparent transmissions.
Also AMF is first passed through when SMF will transmit downlink NAS message, and UE is transparent to by N1 interfaces by AMF.AMF for
The NAS message that SMF is sent is without parsing.The N2 interface messages that SMF is transferred to RAN are also required to first pass through AMF, lead to by AMF
It crosses N2 interfaces and is transparent to RAN.The message that AMF is sent to SMF RAN does not parse.
The flow of Service Request is as shown in Figure 2：
Step 201, UE send the Service Request message of NAS to AN (for example, RAN)；
Service Request are transferred to AMF by step 202, AN；
It should be noted that because Service Request are a relevant processes of MM, so AMF can handle Service
This message of Request.
Unlike LTE, in LTE system Service Request message need not with carrying (bearer) ID,
It can be PDN connections that UE establish all activated state that MME, which is received after NAS message,.And in 5G systems, then this process is carried out excellent
Change.UE can carry PDU session ids (session ID) in the NAS Service Request message of transmission, be used to indicate
Network is only that UE establishes part PDN session connections.Network receives the rear PDU sessions that request is only established for UE, is built without asking
Vertical PDU sessions will not then initiate N2 interfaces and eat dishes without rice or wine to connect.
Step 203 carries out safety certification correlated process；
It should be noted that this safety certification correlated process is mainly realized by certification security function (AUSF) entity.
If containing PDU session ID, AMF in step 204, Service Request message to corresponding
SMF sends message, and notice SMF is this PDU session establishments N2 and empty port load-supporting；
It should be noted that if UE requests multiple PDU session ID, and these different PDU session
It is serviced for it by different SMF, then AMF will send message to different SMF respectively.
Step 205, SMF are PDU session establishment N2 interfaces and empty port load-supporting；
SMF distributes the interface in the user plane mark and IP address of uplink, is sent to AMF preparations and passes to RAN.
The relevant information of session management that step 206, AMF are received to RAN transparent transmission steps 205；
Step 207, RRC empty port load-supportings are established；
UE carries out transmitting uplink data after the completion of step 208, empty port load-supporting are established；
Step 209, RAN to core net return user plane establish corresponding message, it includes RAN distribution user plane mark and
IP address；
The message received in step 209 is sent to SMF by step 210, AMF；
Step 211, SMF and port core function (Port Core Function, PCF) interact；
Step 212, SMF send update request to registered permanent residence function (User Port Function, UPF)；
Step 213, UPF feed back response message to SMF；
It should be noted that step 212 and step 213 are mainly accomplished that：The interface in the user plane mark that SMF distributes RAN
Knowledge is transferred to UPF, is used for downlink data transmission.
To AMF returning response message, this PDU session of instruction AMF is successfully established by step 214, SMF.
As shown in above-mentioned steps, UE may ask to establish multiple PDU session connections steps 204 need in session management procedure
The request for establishing PDU session connections is sent to different SMF, AMF then can receive feedback information from multiple SMF.
How AMF disputes on the RAN presence that passes to received in step 205 at present, and a kind of handle is that AMF waitings have received
After the feedback information of all SMF, RAN is passed to together in N2 interfaces, the benefit of this processing is the reduction of the signaling of N2 interfaces
The shortcomings that interacting, bringing is the delay that can increase PDU sessions；Another kind processing is AMF without waiting for receiving all SMF interfaces
Feedback information, but RAN is just passed to by N2 interfaces after receiving the feedback information of a SMF.The benefit of this processing is can
To reduce the time delay of PDU session establishments, but increase the signaling procedure of N2 interfaces.
A current trend is that latter processing mode, AMF is used to be sent out to RAN without waiting for the message of all SMF
It send, but the message for receiving a SMF is just sent to RAN.The sides RAN also can be to receive a N2 when eating dishes without rice or wine to establish empty port load-supporting
The user plane connection of interface just establishes an empty port load-supporting when establishing.Unlike LTE, in LTE system, UE can basis
The empty port load-supporting situation that RRC is established and core net synchronous bearer state.The PDN connections of carrying are not established for RRC, UE's
NAS locally deactivates these PDN connections.But in 5G, this processing of UE with regard to improper because different PDU sessions by
Different SMF is serviced, and causes the response time of SMF less consistent, and what RAN initiated RRC to UE respectively eats dishes without rice or wine to establish process, institute
It cannot be completed according to the loading establishing process of RRC with UE synchronous with core net.
UE can not complete the PDU session synchronization processes with core net by RRC processes in 5G systems at present, if UE initiations are built
Stand a certain PDU sessions, and SMF or RAN have rejected this PDN session foundation request, currently without method notice UE this
PDU session establishments fail.
The present invention is directed in 5G systems, and UE can not complete the PDU session synchronization processes with core net by RRC processes,
The problem of influencing network communication, provides a kind of conversation managing method, terminal, management function entity and access network node.
Embodiment one
As shown in figure 3, the conversation managing method of the embodiment of the present invention, including：
Step 31, during service request, the protocol Data Unit PDU that network side establishes terminal request not successfully is received
The session establishment failed message fed back when session includes session label information in the session establishment failed message；
It should be noted that the network side can be core-network side, or access net side；As the SMF of core-network side
When entity can not be the connection of PDU session establishment user planes, it will cause session establishment failures, or as access net refusal PDU
When session, session establishment failure will also result in.Especially, it should be noted that particularly which PDU known for the ease of terminal
Session establishment fails, and can should be comprising session label information, such as the session label information in the session establishment failed message
PDU session ID。
Step 32, the deactivation of session corresponding with the session label information is carried out.
When terminal learns that network side can not be the carrying of some session establishments, then need to delete these local sessions.
It should be noted that the session establishment failed message is usually Non-Access Stratum (NAS) message.
During specific implementation, following realization method may be used in step 31：
Mode one, when network side establishes the PDU sessions of terminal request not successfully, receive access and mobile management function to ps domain
(AMF) the session establishment failed message that entity is sent.
It should be noted that because AMF entities are directly communicated with terminal, and session whether establish be typically unsuccessfully by
SMF entities determine, when SMF entities know the case where session establishment fails, can send session establishment to AMF entities
The instruction message of failure, AMF entities generate session establishment failed message according to the instruction message and are transferred to terminal.
Mode two, when network side establishes the PDU sessions of terminal request not successfully, it is real to receive conversation management functional (SMF)
Body sends and via the session establishment failed message of AMF entity transparent transmissions.
It should be noted that when SMF entities know the case where session establishment fails, session establishment mistake can be directly generated
Message is lost, and the session establishment failed message is passed into terminal, because SMF entities can not be with terminal direct communication, so SMF is real
Body needs that the session establishment failed message is first passed to AMF entities, and AMF entities do not carry out the session establishment failed message any
Processing, is directly forwarded to terminal.
Because session establishment may be unsuccessfully to net refusal PDU sessions by access can not either to be built for PDU sessions by SMF entities
Caused by the connection of vertical user plane, when session establishment failure nets refusal PDU sessions by access to be caused, access net needs feeding back conversation
The identification information for establishing failure gives SMF entities, SMF entities to generate the instruction message of session establishment failure according to the identification information
Or session establishment failed message.
It should also be noted that, terminal carry out corresponding with session label information session it is deactivated after,
It usually requires feedback response message and gives SMF entities.
The realization method of the present invention is described as follows in a particular application separately below.
One, when the refusal PDU session establishments request of SMF entities
The specific implementation flow of the embodiment of the present invention is：
Step 41, UE send the Service Request message of NAS to RAN；
Service Request are transferred to AMF by step 42, RAN；
Step 43 carries out safety certification correlated process；
It should be noted that the realization method of step 41-43 is identical as the realization method of step 201-203.
The PDU session ID that step 44, AMF are asked according to UE send request to corresponding SMF and establish PDU sessions
Message；
If this PDU session has discharged in step 45, SMF or SMF can not be this PDU session establishment user
Face connects, then returns to service request refuse information to AMF, indicate this user plane connection failure；
Step 46, AMF return to NAS message to UE, wherein PDU session ID are carried, for complete to UE instructions UE
At the transition between states of Idle state to connected state, but this PDU session establishment fails, and UE will deactivate the PDU sessions after receiving.
It should be noted that if there is multiple PDU session establishments fail, AMF can wait for the response for having received other SMF
UE is notified by a NAS message afterwards, at this point, will include multiple PDU session ID in the NAS message of step 46.If there is
Multiple PDU session establishments failures, AMF are sending NAS message after can also being responded without waiting for all SMF are received to UE, and
It is to receive the response of a SMF just to return to failure news to UE, at this point, including 1 PDU in the NAS message of step 46
session ID。
Two, when RAN refusal PDU session establishments requests
The specific implementation flow of the embodiment of the present invention is：
Step 51, UE send the Service Request message of NAS to RAN；
Service Request are transferred to AMF by step 52, RAN；
Step 53 carries out safety certification correlated process；
It should be noted that the realization method of step 51-53 is identical as the realization method of step 201-203.
The PDU session ID that step 54, AMF are asked according to UE send request to corresponding SMF and establish PDU sessions
Message；
Step 55, SMF initiate PDU sessions and establish process, and the connection of N3 interface user planes is established to RAN.It is wrapped in N11 signalings
The interface identifier and IP address of including core network user plane.
The relevant information of session management that step 56, AMF transparent transmissions receive；
If step 57, RAN can not receive the PDU sessions of some or all of core network requests, RAN is returned to SMF to be refused
Message indicates the information for the PDU sessions not being successfully established.
Step 58, AMF will receive information and pass to SMF in step 57；
Step 59 returns to service request refuse information to AMF, indicates the user plane connection failure of this PDU session；
Step 510, AMF return to NAS message to UE, wherein PDU session ID are carried, for having indicated UE to UE
Transition between states of the Idle state to connected state is completed, but this PDU session establishment fails.UE will deactivate the PDU meetings after receiving
Words.
It should be noted that if there is multiple PDU session establishments fail, AMF can wait for the response for having received other SMF
UE is notified by a NAS message afterwards, at this point, will include multiple PDU session ID in the NAS message of step 56.If there is
Multiple PDU session establishments failures, AMF are sending NAS message after can also being responded without waiting for all SMF are received to UE, and
It is to receive the response of a SMF just to return to failure news to UE, at this point, including 1 PDU in the NAS message of step 56
session ID。
It should be noted that returning to NAS to UE in final step described in above-mentioned realization method one and realization method two
Message is initiated by AMF.The NAS message of refusal can also be directly initiated by SMF, which passes through UE by AMF.
PDU sessions described in instruction UE are not successfully established.UE is local after receiving to deactivate the PDU sessions to SMF returning response message.
The embodiment of the present invention, during the service request for solving 5G, when the connection that network has rejected certain PDU sessions is built
The problem of how notifying terminal immediately ensure that terminal is synchronous with the PDU sessions of core-network side, and ensure that network communication can
It leans on.
