It is a kind of possible communication system architecture schematic diagram that the embodiment of the present invention uses referring to Fig. 1.As shown in Figure 1, can To find out, access network equipment can be connected at least one terminal device, for example, access network equipment 101 is set with terminal respectively Standby 104 are connected with terminal device 105, and access network equipment 102 is connected with terminal device 106 and terminal device 107 respectively.Core Heart net equipment can be connected at least one access network equipment, for example, access network equipment 101 and access network equipment 102 are distinguished It is connected with equipment of the core network 103.

Based on communication system architecture figure shown in FIG. 1, terminal device is during registering or carrying out TAU/RAU, eventually End equipment may inform that the network slice of its request of access network equipment (can be understood as desiring access to or can accessing Network slice) information, the network slice information and present terminal equipment of the request that access network equipment is sent according to terminal device Location (such as locating TA) will either give RA that terminal device distributes (or the cell that terminal device is presently in Or base station) support network slice etc. for terminal device finally distribute one permission network slice information (Allowed NSSAI), it can indicate that terminal device allows to initiate the corresponding business of Allowed NSSAI.

It is understood that the network slice information for the permission of terminal device distribution can be described as network side permission eventually The network slice that end equipment uses, or can be described as the network that network side allows terminal device to access and be sliced, the present invention is real Example is applied not limit this.

Specifically, the network slice information of permission may include the instruction information of one or more network slice, In current Acceditation Area or tracking area, one or more net that terminal device can only include in the network slice information of permission The corresponding network slice of the instruction information of network slice is upper could to initiate session.For example, the network slice of permission includes network It is sliced #1, network slice #2, network slice #3 and network and is sliced #4, then any one of terminal device in current TA or RA It may only be all sliced on #1, network slice #2, network slice #3 and network slice #4 in network in cell and initiate session.It can manage The network slice of solution, permission can also be not limited in Acceditation Area or tracking area, such as can also be referred in current base station Terminal device is allowed to initiate the network slice of session in coverage area or in cell coverage area, does not limit in this application System.It is appreciated that the network allowed, which is sliced, may be used to indicate that core net supports terminal device in current TA or RA The network slice of session is initiated, i.e. core-network side (not including access net side) allows terminal device to send out in current TA or RA Play the network slice of session.For example, terminal device can support network slice #1, network slice #2, network slice #3 and Network is sliced #4, and the network slice that equipment of the core network is supported in terminal device current TA or RA is that network is sliced #1, net Network slice #2 and network slice #3, access network equipment A and access network equipment B belong to the current TA or RA of terminal device, and Access network equipment A supports network slice #1 and network is sliced #2, and access network equipment B supports network slice #1 and network to be sliced # 3, in the above scenario, equipment of the core network is that the network slice of the permission of terminal device distribution may include that network is sliced #1, net Network is sliced #2 and network is sliced #3, then terminal device can be in network when terminal device is moved to access network equipment B It is sliced #1 and network slice #3 and initiates session (but #2 cannot be sliced in network and initiate session), when terminal device is moved to access When net equipment A, terminal device can be sliced #1 in network and network slice #2 initiates session and (but cannot cut in network Piece #3 initiates session).Due to the mobility of terminal device, the protokaryon heart of the variation of the information of registration or offer network slice service Reasons, the network side equipment such as unavailable of net equipment need to redistribute Allowed NSSAI (new for terminal device Allowed NSSAI), it is also possible to equipment of the core network is replaced for terminal device.For example, network side equipment can be AMF or net Network is sliced selection function (network slice selection function, NSSF).

And scheme is needing to redistribute Allowed NSSAI for terminal device or is needing for terminal device replacement now In the case where equipment of the core network, (core net for providing network slice service before replacement for terminal device is set source equipment of the core network It is standby) pass through access network equipment to terminal device transmission Non-Access Stratum (Non-access stratum, NAS) signaling, NAS letter The new Allowed NSSAI for including equipment of the core network for terminal device distribution is enabled, terminal device, will after receiving NAS signaling It itself is released to idle (idle) state, and carries out area update (such as RAU) process.Equipment of the core network also can choose appropriate Time discharges the context of terminal device, and the state for recording terminal device is Idle state.Very likely occurs terminal in this way The state of the terminal device of state and the equipment of the core network record of equipment itself is that inconsistent situation occurs, and causes to communicate nothing Method is normally carried out.

In practice, the state of terminal device includes idle (idle) state, connection (connected) state and deactivation (inactive) state.The case where being connected state for terminal device, in a kind of possible situation, if terminal device does not receive this NAS signaling, then terminal device will not be released to Idle state, that is to say, that equipment of the core network can not determine that terminal device is It is no receive the NAS signaling (i.e. equipment of the core network does not know whether terminal device enters Idle state) in the case where, core net is set It is standby that release the context of terminal device and record the state of terminal device be Idle state so that the state of terminal device itself with The state of the terminal device of equipment of the core network record is inconsistent.However can be remained unchanged due to terminal device in this way in connected state, During terminal device sends data to network side, it can not be continued as because of the equipment of the core network, corresponding service is provided And cause to send and fail, reduce effective transmission of the data of terminal device.In another case, equipment of the core network is released not in time The context of terminal device is put, the state for still recording terminal device is connected state, and access network equipment also will be considered that terminal at this time Equipment is connected state, but terminal device comes into Idle state in the case where receiving NAS signaling, so that terminal device itself The state for the terminal device that state and equipment of the core network, access network equipment record be it is inconsistent, give access network equipment and core Net equipment belt carrys out certain wasting of resources, can be because of terminal device in addition during the lateral terminal device of network sends data Idle state is entered and data is caused to send failure.

The case where being deactivated state for terminal device, needs access network equipment to find the terminal device by paging, and In the case where establishing communication connection, which is sent to terminal device.In a kind of possible situation, if paging Failure, still can not be sent to terminal device for NAS signaling.Equipment of the core network releases the context of terminal device and records end The state of end equipment is Idle state, so that the state of the terminal device of the state of terminal device itself and equipment of the core network record is Inconsistent.In the case where alternatively possible, terminal device has passed through paging and has discharged the state of itself for Idle state, but core Heart net equipment discharges the context of terminal device not in time, and the state for still recording terminal device is connected state, accesses net at this time Equipment also will be considered that terminal device is connected state, but terminal device comes into Idle state in the case where receiving NAS signaling, makes Terminal device itself state and equipment of the core network, access network equipment record terminal device state be it is inconsistent, give Access network equipment and equipment of the core network bring certain wasting of resources.
