Apparatus and method for paging user equipment and communications system
A user equipment (UE) includes: a memory configured to store a plurality of instructions; and a processor coupled to the memory and configured to execute the plurality of instructions to: calculate a first paging group index of the UE by using the following formula: Paging_GroupID=floor(UE_ID/nB); where, Paging_GroupID is the first paging group index, UE_ID based on an identity of the UE, nB is a parameter associate with paging occasions and floor denotes a rounded down operation.
1. A user equipment (UE) comprising:
a memory configured to store a plurality of instructions; and
a processor coupled to the memory and configured to execute the plurality of instructions to:
calculate a second paging group index of a second-grade paging group based on a first paging group index of a first-grade paging group and a parameter obtained by the UE via system information, the first paging group index Paging_GroupID is defined by the following formula:
Paging_GroupID=floor(UE_ID/ nB );
where, Paging_GroupID is the first paging group index, UE_ID is based on an identity of the UE, nB is a parameter associate with paging occasions of a cell in paging cycle and floor denotes a rounded down operation,
wherein the second paging group index is used to determine which narrowband or which carrier the UE performs a paging message reception.
2. The UE according to claim 1 , wherein, the identity of the UE is an international mobile subscriber identity.
3. The UE according to claim 1 , wherein the processor is further configured to receive cycle information transmitted by the base station, the cycle information indicating that no monitoring is needed within multiple paging cycles after a paging message is received.
4. A base station comprising:
a memory configured to store a plurality of instructions;
processor coupled to the memory and configured to execute the plurality of instructions to:
calculate a second paging group index of a second-grade paging group on a first paging group index of a first-grade paging group and a parameter obtained by the UE via system information, the first paging group index Paging_GroupID is defined by the following formula:
Paging_GroupID=floor(UE_ID/ nB );
where, Paging_GroupID is the first paging group index, UE_ID is based on an identity of a user equipment (UE), nB is a parameter associate with paging occasions of a cell in a paging cycle and floor denotes a rounded down operation,
wherein the second paging group index is used to determine which narrowband or which carrier the UE performs a paging message reception.
5. The base station according to claim 4 , wherein the processor is further configured to transmit cycle information, the cycle information indicating that no monitoring is needed within multiple paging cycles after the UE receives a paging message.
