Detailed Description
As described in the above background art, when performing cell handover, the source base station does not know whether the ue can be handed over to the PUG cell.
In the embodiment of the invention, the user equipment determines the information of the target cell, the information of the target cell can represent whether the user equipment is an authorized user of the target cell, and the information of the target cell is sent to the source base station. The source base station can acquire whether the user equipment has corresponding authority to reside in the target cell according to the information of the target cell sent by the user equipment, and further determine whether to switch the user equipment to the target cell.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
An embodiment of the present invention provides a method for mobility management of a user equipment, which is described in detail below with reference to fig. 1 through specific steps.
In the embodiment of the present invention, the mobility management method of the user equipment provided in the following steps S101 to S102 may be executed by the user equipment. Specifically, the following steps S101 to S102 may be executed by a chip having data processing capability in the user equipment, such as a baseband chip; or by a chip module comprising a baseband chip in the user equipment.
Step S101, information of the target cell is determined.
In a specific application, it is known that, in the neighboring cell measurement configuration configured for the user equipment, the source base station may not configure the measurement configuration of the target cell for the user equipment, and therefore, the source base station may configure the user equipment to feed back information of the target cell.
In a specific implementation, the source base station device may issue the first indication information to the user equipment, where the first indication information may be used to trigger the user equipment to feed back information of the target cell. The user equipment may receive the first indication information issued by the source base station, and determine the information of the target cell according to the first indication information issued by the source base station.
In the embodiment of the present invention, the source base station may send the first indication Information to the ue through a high-level signaling, may send the first indication Information to the ue through Downlink Control Information (DCI), and may send the first indication Information to the ue through other types of signaling such as MAC CE. The higher layer signaling may be Radio Resource Control (RRC) signaling.
In this embodiment of the present invention, the identification information of the target cell may be used to characterize which cell the target cell is, and the authorization information of the target cell may be used to characterize whether the user equipment is an authorized user of the target cell.
It should be noted that, if the user equipment determines that the user equipment is not an authorized user of the target cell, the user equipment may not generate the information of the target cell, and subsequently, does not need to send the information of the target cell. Therefore, when the user equipment judges that the user equipment is an authorized user of the target cell, the information of the target cell is determined, and the subsequent operation of transmitting the information of the target cell is performed.
That is, if the user equipment does not perform the operation of determining the information of the target cell, it can be confirmed that the user equipment is not an authorized user of the target cell. The user equipment determines information of the target cell only if the user equipment is an authorized user of the target cell. At this time, the authorization information of the target cell may be used to characterize that the user equipment is an authorized user of the target cell.
In a particular implementation, the target cell may be a closed cell or a hybrid cell. Wherein, the closed cell only supports the access of authorized user equipment; in the mixed cell, any user equipment can access, but the service quality of the authorized user equipment is preferentially guaranteed.
In the embodiment of the present invention, the target cell may be a Closed User Group (CUG) cell in which the ue can camp.
For example, the CUG cell currently covering user equipment 1 is CUG cell 1, and user equipment 1 is not an authorized user of CUG cell 1. After receiving the first indication information, the user equipment 1 feeds back the identification information of the target cell to the source base station as follows: the identification information of the CUG cell is 1; the user equipment 1 of the target cell that is fed back to the source base station is not an authorized user equipment.
As another example, the CUG cell currently covering the user equipment 2 is CUG cell 1, and the user equipment 2 is an authorized user of CUG cell 1. After receiving the first indication information, the user equipment 2 feeds back authorization information of the target cell to the source base station as follows: the identification information of the CUG cell is 1, and the user equipment 2 is authorized user equipment of the CUG cell 1.
And step S102, sending the information of the target cell.
In an implementation, after determining the authorization information of the target cell, the user equipment may send the information of the determined target cell. In the embodiment of the present invention, the determined information of the target cell may be sent to the source base station.
In a specific implementation, after receiving information of the target cell fed back by the user equipment, the source base station may learn whether the user equipment can camp on the target cell. After determining to switch the user equipment to the target cell, the source base station may send information of the target cell to the target base station corresponding to the target cell.
The source base station may send handover indication information to the user equipment after determining to handover the user equipment to the target cell. After receiving the handover indication information, the user equipment may send authorization information of the target cell to the target base station.
After receiving the information of the target cell sent by the source base station and the authorization information of the target cell sent by the user equipment, the target base station can judge the authorization relationship of the user equipment to determine whether the user equipment is an authorized user, and further determine whether the user equipment can reside in the target cell.
In the embodiment of the present invention, the source base station may be a macro base station, or may also be a 5G access point device or other types of base stations.
In a specific implementation, the user equipment may access the target cell through the key. At this time, in the information of the target cell sent by the user equipment to the source base station, besides the identification information of the target cell and the authorization information of the target cell, the information may also include message integrity check information corresponding to the target cell.
In an embodiment of the present invention, the message Integrity Check information may be a Message Integrity Check (MIC) value. The MIC value may be generated from the CUG key, or from a derivative of the CUG key. The MIC value may also be an integrity check key generated based on the CUG key and all information in the system message except the MIC, or an integrity check code generated based on a derivative key of the CUG key and all information in the system message except the MIC. The CUG key is a key required for the ue to access the target cell, that is, the ue needs to input a corresponding key to obtain authorization when accessing the CUG cell.
In the embodiment of the present invention, the authorization information of the target cell may further include a random number corresponding to the message integrity check information. At this time, the ue may also send a random number corresponding to the message integrity check information to the source base station.
At this time, the information of the target cell sent by the user equipment, received by the source base station, includes: identification information of the target cell, authorization information of the target cell, message integrity check information of the target cell, and a random number corresponding to the message integrity check information. The information of the target cell sent by the user equipment to the target base station comprises: authorization information of the target cell, message integrity check information of the target cell, and a random number corresponding to the message integrity check information.
In a specific implementation, when a 4-step contention Random Access Channel (RACH) is used, the ue may send grant information of the target cell to the target base station using msg3 or msg 5. And in the non-contention RACH, transmitting the authorization information of the target cell to the target base station during the first uplink data transmission after the RAR. In the two-step RACH, the user equipment may carry the grant information of the target cell in msgA and transmit to the target base station.
In the specific implementation, the user equipment can also access the target cell based on a synchronous authorization method. And after receiving the switching indication information, the user equipment sends authorization information of the target cell to the target base station. The target base station can judge whether the user equipment is allowed to reside according to the synchronization authorization relationship stored by the target base station. The target base station may also send a request to the core network, and the core network determines whether to allow the ue to camp on.
In the embodiment of the present invention, the target base station may also request the core network for authorization information. After receiving the request of the target base station, the core network sends authorization information to the target base station, and the target base station judges whether the user equipment is allowed to reside.
In a specific implementation, before the ue is switched to the target cell, the core network still needs to continue to send the paging message according to a situation that the ue is not switched, so as to ensure that the ue is reachable. After the user equipment is switched to the target cell, the core network can send a paging message according to the condition that the user equipment is switched to be finished so as to ensure that the user equipment can be reached.
Therefore, in the embodiment of the present invention, the user equipment determines the information of the target cell, and the information of the target cell can represent whether the user equipment is an authorized user of the target cell, and sends the information of the target cell to the source base station. The source base station can acquire whether the user equipment has corresponding authority to reside in the target cell according to the information of the target cell sent by the user equipment, and further determine whether to switch the user equipment to the target cell.
Referring to fig. 2, another method for mobility management of user equipment in the embodiment of the present invention is shown, and the following detailed description is made through specific steps.
In the embodiment of the present invention, the user equipment mobility management method provided in the following steps S201 to S202 may be executed by the source base station. Specifically, the following steps S201 to S202 may be executed by a chip having data processing capability in the source base station, or by a chip module including a data processing chip in the source base station.
Step S201 receives information of the target cell.
Step S202, the information of the target cell is sent to the target base station corresponding to the target cell.
In a specific application, it is known that, in the neighboring cell measurement configuration configured for the user equipment, the source base station may not configure the measurement configuration of the target cell for the user equipment, and therefore, the source base station may configure the user equipment to feed back information of the target cell.
In a specific implementation, the source base station device may issue first indication information to the user equipment, where the first indication information may be used to trigger the user equipment to feed back information of the target cell. After receiving the first indication information issued by the source base station, the user equipment may determine information of the target cell according to the first indication information issued by the source base station, and send the determined information of the target cell to the source base station.
In the embodiment of the present invention, the source base station may send the first indication Information to the ue through a high-level signaling, may send the first indication Information to the ue through Downlink Control Information (DCI), and may send the first indication Information to the ue through other types of signaling such as MAC CE. The higher layer signaling may be Radio Resource Control (RRC) signaling.
In this embodiment of the present invention, the identification information of the target cell may be used to characterize which cell the target cell is, and the authorization information of the target cell may be used to characterize whether the user equipment is an authorized user of the target cell.
It should be noted that, if the user equipment determines that the user equipment is not an authorized user of the target cell, the user equipment may not generate the information of the target cell, and subsequently, does not need to send the information of the target cell. Therefore, when the user equipment judges that the user equipment is an authorized user of the target cell, the information of the target cell is determined, and the subsequent operation of transmitting the information of the target cell is performed.
That is, if the user equipment does not perform the operation of determining the information of the target cell, it can be confirmed that the user equipment is not an authorized user of the target cell. The user equipment determines information of the target cell only if the user equipment is an authorized user of the target cell. At this time, the authorization information of the target cell may be used to characterize that the user equipment is an authorized user of the target cell.
In a particular implementation, the target cell may be a closed cell or a hybrid cell. Wherein, the closed cell only supports the access of authorized user equipment; in the mixed cell, any user equipment can access, but the service quality of the authorized user equipment is preferentially guaranteed.
In the embodiment of the present invention, the target cell may be a Closed User Group (CUG) cell in which the ue can camp.
For example, the CUG cell currently covering user equipment 1 is CUG cell 1, and user equipment 1 is not an authorized user of CUG cell 1. After receiving the first indication information, the user equipment 1 feeds back the identification information of the target cell to the source base station as follows: the identification information of the CUG cell is 1; the user equipment 1 of the target cell that is fed back to the source base station is not an authorized user equipment.
As another example, the CUG cell currently covering the user equipment 2 is CUG cell 1, and the user equipment 2 is an authorized user of CUG cell 1. After receiving the first indication information, the user equipment 2 feeds back authorization information of the target cell to the source base station as follows: the identification information of the CUG cell is 1, and the user equipment 2 is authorized user equipment of the CUG cell 1.
In a specific implementation, after receiving information of the target cell fed back by the user equipment, the source base station may learn whether the user equipment can camp on the target cell. After determining to switch the user equipment to the target cell, the source base station may send information of the target cell to the target base station corresponding to the target cell.
The source base station may send handover indication information to the user equipment after determining to handover the user equipment to the target cell. After receiving the handover indication information, the user equipment may send authorization information of the target cell to the target base station.
After receiving the information of the target cell sent by the source base station and the authorization information of the target cell sent by the user equipment, the target base station can judge the authorization relationship of the user equipment to determine whether the user equipment is an authorized user, and further determine whether the user equipment can reside in the target cell.
In the embodiment of the present invention, the source base station may be a macro base station, or may also be a 5G access point device or other types of base stations.
In a specific implementation, the user equipment may access the target cell through the key. At this time, in the information of the target cell sent by the user equipment to the source base station, besides the identification information of the target cell and the authorization information of the target cell, the information may also include message integrity check information corresponding to the target cell.
In the embodiment of the present invention, the message integrity check information may be a MIC value. The MIC value may be generated from the CUG key, or from a derivative of the CUG key. The MIC value may also be an integrity check key generated based on the CUG key and all information in the system message except the MIC, or an integrity check code generated based on a derivative key of the CUG key and all information in the system message except the MIC. The CUG key is a key required for the ue to access the target cell, that is, the ue needs to input a corresponding key to obtain authorization when accessing the CUG cell.
In the embodiment of the present invention, the authorization information of the target cell may further include a random number corresponding to the message integrity check information. At this time, the ue may also send a random number corresponding to the message integrity check information to the source base station.
At this time, the information of the target cell sent by the user equipment, received by the source base station, includes: identification information of the target cell, authorization information of the target cell, message integrity check information of the target cell, and a random number corresponding to the message integrity check information. The information of the target cell sent by the user equipment to the target base station comprises: authorization information of the target cell, message integrity check information of the target cell, and a random number corresponding to the message integrity check information.
In a specific implementation, when a 4-step contention Random Access Channel (RACH) is used, the ue may send grant information of the target cell to the target base station using msg3 or msg 5. And in the non-contention RACH, transmitting the authorization information of the target cell to the target base station during the first uplink data transmission after the RAR. In the two-step RACH, the user equipment may carry the grant information of the target cell in msgA and transmit to the target base station.
In the specific implementation, the user equipment can also access the target cell based on a synchronous authorization method. And after receiving the switching indication information, the user equipment sends authorization information of the target cell to the target base station. The target base station can judge whether the user equipment is allowed to reside according to the synchronization authorization relationship stored by the target base station. The target base station may also send a request to the core network, and the core network determines whether to allow the ue to camp on.
In the embodiment of the present invention, the target base station may also request the core network for authorization information. After receiving the request of the target base station, the core network sends authorization information to the target base station, and the target base station judges whether the user equipment is allowed to reside.
