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, and the information of the target cell can represent whether the user equipment is an authorized user of the target cell or not 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 then determine whether to switch the user equipment into the target cell.
In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below.
The embodiment of the invention provides a mobility management method of user equipment, and the mobility management method is described in detail through specific steps with reference to fig. 1.
In the embodiment of the present invention, the mobility management method of the ue provided in the following steps S101 to S102 may be executed by the ue. Specifically, the following steps S101 to S102 may be performed by a chip with data processing capability in the ue, such as a baseband chip; or by a chip module in the user equipment containing the baseband chip.
Step S101, determining information of a target cell.
In a specific application, the source base station may not configure the measurement configuration of the target cell for the user equipment in the neighbor cell measurement configuration configured for the user equipment, and therefore, the source base station may configure the user equipment to feed back the 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. The user equipment can 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 invention, the source base station can issue the first indication information to the user equipment through high-layer signaling, can issue the first indication information to the user equipment through downlink control information (Downlink Control Information, DCI), and can issue the first indication information to the user equipment through other types of signaling such as MAC CE. Wherein the higher layer signaling may be radio resource control (Radio Resource Control, RRC) signaling.
In a specific implementation, the information of the target cell may include identification information of the target cell and authorization information of the target cell, and in the 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 ue determines that the ue is not an authorized user of the target cell, the ue may not generate information of the target cell, and then need not 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 sending the information of the target cell is performed.
That is, if the user equipment does not perform an operation of determining information of the target cell, it may be confirmed that the user equipment is not an authorized user of the target cell. The user equipment determines the information of the target cell only if the user equipment is an authorized user of the target cell. At this point, 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 implementations, 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 hybrid cell, any user equipment can access, but the service quality of the authorized user equipment is preferentially ensured.
In an embodiment of the present invention, the target cell may be a closed subscriber group (Closed User Group, CUG) cell in which the user equipment can camp.
For example, the CUG cell currently covering the user equipment 1 is CUG cell 1, and the 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 fed back to the source base station is not an authorised 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 the 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 an authorized user equipment of the CUG cell 1.
Step S102, information of the target cell is sent.
In a specific implementation, after determining the authorization information of the target cell, the user equipment may send the determined information of the target cell. In the embodiment of the invention, the determined information of the target cell can be sent to the source base station.
In a specific implementation, after receiving the information of the target cell fed back by the user equipment, the source base station can learn whether the user equipment can reside in 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 ue 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 relation of the user equipment to determine whether the user equipment is an authorized user or not, and further determine whether the user equipment can reside in the target cell or not.
In the embodiment of the invention, the source base station can be a macro base station, a 5G access point device or other types of base stations.
In an implementation, the user equipment may access the target cell through a key. At this time, the information of the target cell sent by the user equipment to the source base station may include information of message integrity check corresponding to the target cell, in addition to identification information of the target cell and authorization information of the target cell.
In an embodiment of the present invention, the message integrity check information may be a message integrity check (Messages 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 other information in the system message except the MIC, or an integrity check code generated from a derivative of the CUG key and all other information in the system message except the MIC. The CUG key is a key required by the user equipment to access the target cell, that is, the user equipment can obtain authorization only by inputting the corresponding key when accessing the CUG cell.
In the embodiment of the invention, the authorization information of the target cell can also comprise 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 and received by the source base station includes: identification information of a 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 an implementation, the user equipment may transmit grant information of the target cell to the target base station using msg3 or msg5 when competing for a random access channel (Random Access Channel, RACH) in 4 steps. And when the RAR is not in competition with the RACH, the authorization information of the target cell is sent to the target base station during the first uplink data transmission after the RAR. In the two-step RACH, the ue may carry the grant information of the target cell in the msgA and send the grant information to the target base station.
In a specific implementation, the user equipment may also access the target cell based on a method of synchronization authorization. After receiving the handover indication information, the user equipment sends authorization information of the target cell to the target base station. The target base station can judge whether to allow the user equipment to reside according to the self-stored synchronous authorization relationship. The target base station may also send a request to the core network, which determines whether the user equipment is allowed to camp on.
In the embodiment of the present invention, the target base station may also request authorization information from the core network. 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 handed over to the target cell, the core network still needs to continue sending paging messages according to the situation that the ue is not handed over, 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 situation that the user equipment is switched to be completed, so as to ensure that the user equipment is reachable.
It can be seen that, in the embodiment of the present invention, the ue determines the information of the target cell, where the information of the target cell can characterize whether the ue 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 then determine whether to switch the user equipment into the target cell.
Referring to fig. 2, another mobility management method for a ue according to an embodiment of the present invention is given, and detailed description is given below through specific steps.
In the embodiment of the present invention, the mobility management method of the ue 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 performed by a chip having a data processing capability in the source base station, or by a chip module including the data processing chip in the source base station.
Step S201, information of a target cell is received.
Step S202, information of the target cell is sent to a target base station corresponding to the target cell.
In a specific application, the source base station may not configure the measurement configuration of the target cell for the user equipment in the neighbor cell measurement configuration configured for the user equipment, and therefore, the source base station may configure the user equipment to feed back the information of the target cell.
In a specific implementation, the source base station device may send 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 sent by the source base station, the user equipment can determine information of the target cell according to the first indication information sent by the source base station, and send the determined information of the target cell to the source base station.
In the embodiment of the invention, the source base station can issue the first indication information to the user equipment through high-layer signaling, can issue the first indication information to the user equipment through downlink control information (Downlink Control Information, DCI), and can issue the first indication information to the user equipment through other types of signaling such as MAC CE. Wherein the higher layer signaling may be radio resource control (Radio Resource Control, RRC) signaling.
In a specific implementation, the information of the target cell may include identification information of the target cell and authorization information of the target cell, and in the 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 ue determines that the ue is not an authorized user of the target cell, the ue may not generate information of the target cell, and then need not 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 sending the information of the target cell is performed.
That is, if the user equipment does not perform an operation of determining information of the target cell, it may be confirmed that the user equipment is not an authorized user of the target cell. The user equipment determines the information of the target cell only if the user equipment is an authorized user of the target cell. At this point, 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 implementations, 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 hybrid cell, any user equipment can access, but the service quality of the authorized user equipment is preferentially ensured.
In an embodiment of the present invention, the target cell may be a closed subscriber group (Closed User Group, CUG) cell in which the user equipment can camp.
For example, the CUG cell currently covering the user equipment 1 is CUG cell 1, and the 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 fed back to the source base station is not an authorised 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 the 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 an authorized user equipment of the CUG cell 1.
In a specific implementation, after receiving the information of the target cell fed back by the user equipment, the source base station can learn whether the user equipment can reside in 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 ue 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 relation of the user equipment to determine whether the user equipment is an authorized user or not, and further determine whether the user equipment can reside in the target cell or not.
In the embodiment of the invention, the source base station can be a macro base station, a 5G access point device or other types of base stations.
In an implementation, the user equipment may access the target cell through a key. At this time, the information of the target cell sent by the user equipment to the source base station may include information of message integrity check corresponding to the target cell, in addition to identification information of the target cell and authorization information of the target cell.
In the embodiment of the 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 other information in the system message except the MIC, or an integrity check code generated from a derivative of the CUG key and all other information in the system message except the MIC. The CUG key is a key required by the user equipment to access the target cell, that is, the user equipment can obtain authorization only by inputting the corresponding key when accessing the CUG cell.
In the embodiment of the invention, the authorization information of the target cell can also comprise 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 and received by the source base station includes: identification information of a 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 an implementation, the user equipment may transmit grant information of the target cell to the target base station using msg3 or msg5 when competing for a random access channel (Random Access Channel, RACH) in 4 steps.
