Description
Technical field
The present invention relates to field of communication technology, in particular to a kind of method, dress that terminal device is switched to Target cell
It sets and base station.
Background technique
With a large amount of uses of machine-type communication MTC, network needs to face the problem of great amount of terminals is linked into network, simultaneously
Different terminals has different characteristics, and diversification is presented in the business of support；Such as the MTC such as automatic vending machine may not be needed to support
Mobility, the MTC such as medical monitoring need to guarantee the real-time Transmission of data, and the MTC devices such as water meter ammeter are then only needed specific
Time carry out small data transmission etc..In order to avoid these MTC devices impact the service of existing user, simultaneously for not
Same user network can provide optimization service appropriate for it, and operator may select to dispose different types of core net；Cause
The UE of this different class of subscriber will be linked into different particular networks.This specific network is referred to as D é cor network.
But in network deployment, it is understood that there may be the network of deployment early period is not due to being upgraded, without supporting D é cor
Network characteristic；Or operator only deploys the scene of D é cor network in some areas when on-premise network.It uses in this case
Family equipment UE just only has access in non-D é cor network, if but when user equipment (UE) is moved to a certain support D é cor characteristic
Perhaps network detects that attach, tracing section updating TAU or road are being adhered in the presence of the D é cor network of UE characteristic for position
NAS message redirection process as shown in Figure 1 will be initiated during updating RAU by area.
Step 1: when first new MME/SGSN receives the attach request/TAU request/RAU of UE initiation
After request message, first new MME/SGSN obtains the UE type information of UE from old MME/SGSN or HSS.
First new MME/SGSN determines whether the D for meeting this UE demand according to the UE type information of UE and the information of configuration
é cor network.
First new MME/SGSN sends NAS redirection request to RAN, carries complete NAS message in request, simultaneously
Identification information comprising the D é cor network that first new MME/SGSN is UE selection.D é cor network is in current agreement
It is identified by MMEGI (E-UTRAN) or Null-NRI/SGSN Group ID (UTRAN/GERAN).
The network node selection function of step 2:RAN node is based on MMEGI Null-NRI/SGSN Group ID
UE selects a new MME/SGSN.
Step 3:eNB/RNC sends Initial UE message to the MME/SGSN of selection, wherein the NAS for carrying UE is asked
Ask information and MMEGI Null-NRI/SGSN Group id information.MMEGI Null-NRI/SGSN Group
Id information indicates that this is the message of a redirection.Second new MME/SGSN cannot be weighed again this NAS message
Orientation.
In addition if UE does not support D é cor network at source cell, and the new cell after switching supports D é cor network, that
The step in Fig. 2 will be executed:
Step 4: when UE is redirected to D é cor network by the MME decision after switching, MME initiates GUTI again to UE
Process, wherein carrying a TAI/RAI not broadcasted.
Step 5:MME/SGSN discharges the connection of the side RAN, and UE is moved to Idle state.
Step 6: the TAI/RAI triggering UE not broadcasted initiates TAU process.MME/SGSN receives TAU/RAU request message.
Step 7:MME/SGSN process according to figure 1 initiates NAS redirection process.
But the scheme of the prior art is since it is considered that compatibility to version terminal before, cannot have shadow to the behavior of UE
It rings, so the project plan comparison finally designed is complicated.It is redirected after especially switching, process is more complicated.At present in agreement
Regulation NAS redirection process can only occur in during the TAU/RAU of UE Idle state, and TAU caused by HO process is cannot to initiate
What NAS was redirected.According to present process, after UE switches, if having left original TA list (tracking zone list),
UE needs to initiate TAU process in handoff procedure.After Deng this process, GUTI is initiated by MME/SGSN and was redistributed
Journey, triggering UE initiates TAU again, and during TAU this time, MME is initiating NAS redirection process.Realize it is complicated, UE and
There are many interaction in network.

With network connection；
Step 123, the terminal device is switched to the Target cell.
The change to the communication process of current mechanism is minimized in the embodiment of the present invention, then above-mentioned steps 121
In, according to terminal device described in existing communication mechanism occur cell switching when, receive the terminal device have access to it is standby
Select target cell list.It should be noted that the alternative target cells are in the coverage area of adjacent base station.Then source base station is looked into
The type identification for seeing the terminal device obtained in step 11 determines the information of target-specific network, according further to receiving
Alternative target cells list, whether the base station where checking alternative target cells therein supports above-mentioned target-specific network
Characteristic therefrom selects a Target cell, and the base station where the Target cell can support the characteristic of above-mentioned target-specific network, then
Show that the Target cell can support the characteristic of above-mentioned target-specific network accordingly, then controlling terminal equipment is switched to determining
Target cell, to complete the switching of dedicated network.
Wherein, judge whether base station supports above-mentioned target-specific by the way that whether base station is connected to the network with above-mentioned target-specific
The characteristic of network；Even base station and above-mentioned target-specific are connected to the network, it is determined that support the spy of above-mentioned target-specific network in base station
Property, if base station is not connected to the network with above-mentioned target-specific, it is determined that do not support the characteristic of above-mentioned target-specific network in base station.
To sum up, in the above embodiment of the present invention, on the basis of reducing the change to existing communication mechanism as far as possible, root
