Description

Method, device and base station for switching terminal equipment to target cell

The invention belongs to the field of communication technologies, and in particular relates to a method, a device and a base station for switching a terminal device to a target cell.

With the large-scale use of machine-type communication MTC, the network needs to face a large number of terminals accessing the network. At the same time, different terminals have different characteristics, and the supported services are diversified; for example, MTCs such as vending machines may not need support. Mobility, medical monitoring and other MTCs need to ensure the instantaneous transmission of data, while MTC equipment such as water meters and electricity meters only need to transmit small data at a specific time. In order to avoid the impact of these MTC devices on the services of existing users, and to provide appropriate optimization services for different user networks, operators may choose to deploy different types of core networks; therefore, UEs of different user categories Will be taken to a different specific network. This particular network is called the Décor network.

However, when the network is deployed, there may be a network that was deployed in the early stage because it is not upgraded and does not support the Décor network feature; or when the network is deployed, the operator only deploys the Décor network in some places. In this case, the user equipment UE can only access the non-Décor network, but if the user equipment UE moves to a location that supports the Décor feature, or the network detects the Décor network with the UE characteristics. There is, in the process of attachment, tracking area update (TAU) or routing area update (RAU), the NAS message redirection process as shown in FIG. 1 will be initiated.

Step 1: After the first new MME/SGSN receives the attach request/TAU request/RAU request message initiated by the UE, the first new MME/SGSN is from the old MME/SGSN or Home Subscriber Server (HSS). The UE type information of the UE is obtained. The first new MME/SGSN determines whether there is a Décor network satisfying the requirements of the UE according to the UE type information of the UE and the configured information.

The first new MME/SGSN sends a NAS redirection request to the RAN, and the request carries the complete NAS message, and includes the identification information of the Décor network selected by the first new MME/SGSN for the UE. In the current agreement, the Décor network is identified by MMEGI (E-UTRAN) or Null-NRI/SGSN Group ID (UTRAN/GERAN).

Step 2: The network node selection function of the RAN node selects a new MME/SGSN for the UE based on the MMEGI or the Null-NRI/SGSN Group ID.

Step 3: The eNB/RNC sends an initial UE message to the selected MME/SGSN, which carries the NAS request information of the UE, and the MMEGI or Null-NRI/SGSN Group ID information. The MMEGI or Null-NRI/SGSN Group ID information indicates that this is a redirected message. The second new MME/SGSN cannot redirect this NAS message again.

In addition, if the UE does not support the Décor network in the source cell, and the switched new cell supports the Décor network, the steps in FIG. 2 will be performed:

Step 4: When the MME after handover decides to redirect the UE to the Décor network, the MME initiates a GUTI re-process to the UE, which carries a TAI/RAI without broadcast.

Step 5: The MME/SGSN releases the RAN side connection, and the UE moves to the idle state.

Step 6: The TAI/RAI without broadcast triggers the UE to initiate a TAU procedure. The MME/SGSN receives the TAU/RAU request message.

Step 7: The MME/SGSN initiates a NAS redirection procedure according to the procedure shown in FIG. 1.

However, the solution of the related art is complicated because the compatibility with the previous version of the terminal is considered and the behavior of the UE cannot be affected. In particular, the redirection occurs after switching, and the process is more complicated. The current protocol stipulates that the NAS redirection process can only occur in the TAU/RAU process in which the UE is idle. The TAU caused by the HO process cannot initiate NAS redirection. According to the current process, after the UE switches, if the original TA list (tracking area list) is left, the UE needs to initiate a TAU process during the handover process. After the process ends, the MME/SGSN initiates the GUTI re-allocation process, triggering the UE to initiate the TAU again. In this TAU process, the MME initiates the NAS redirection process. The implementation is complex, and there are many interactions between the UE and the network.

It should be noted that the candidate target cells are all within the coverage of adjacent base stations. Then, the source base station checks the type identifier of the terminal device obtained in step 11, determines the information of the target private network, and further checks whether the base station where the candidate target cell is located supports the above according to the received candidate target cell list. Selecting a target cell from the characteristics of the target private network, wherein the base station where the target cell is located can support the characteristics of the target private network, and correspondingly indicating that the target cell can support the characteristics of the target private network, then controlling the terminal The device switches to the determined target cell to complete the handover of the private network.
