Method and device for paging transmission and reception of terminal supporting multiple sims in next-generation mobile communication system
The present disclosure relates to a communication technique for combining an IoT technology with a 5G communication system for supporting a higher data transmission rate than a 4G system, and a system for same. The present disclosure may be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart or connected cars, healthcare, digital education, retail businesses, security and safety-related services, etc.) based on 5G communication technology and IoT-related technology. According to an embodiment of the present disclosure, a method to be performed by a terminal of a wireless communication system is provided. The method is characterized by including the steps of: receiving first system information through a cell of a first base station; identifying whether a first paging occasion confirmed on the basis of the first system information overlaps a second paging occasion for a second base station; transmitting a message to the first base station when the first paging occasion overlaps the second paging occasion and an indicator indicating that the cell of the first base station supports paging adjustment is included in the first system information, said message including at least one first parameter related to the paging adjustment; receiving a message, including at least one second parameter determined on the basis of the at least one first parameter, from the first base station; and receiving a paging message on the basis of the at least one second parameter.
1. A method performed by a user equipment (UE) with multiple subscriber identity modules (SIMs) in a communication system, the method comprising:
receiving, from a base station of a cell associated with a SIM among the multiple SIMs, system information including paging related configuration information, wherein the paging related configuration information includes information whether the cell supports an adjustment of paging occasion (PO) associated with the SIM;
in case that the cell is identified to support the adjustment, determining whether a PO collision is detected based on the paging related configuration information;
in case that the PO collision is detected, transmitting, to the base station, a radio resource control (RRC) setup request message including a cause value indicating that the UE requests an RRC connection establishment with the base station for the adjustment of the PO associated with the SIM;
receiving, from the base station, an RRC setup message for establishing the RRC connection based on the cause value; and
transmitting, to the base station, an RRC setup complete message including a registration request message based on an identification that the PO collision is detected.
2. The method of claim 1 , further comprising:
receiving, from an access and mobility management function (AMF) entity via the base station, a registration accept message,
wherein the registration accept message includes information used to modify a timing of a paging occasion (PO) associated with the SIM.
3. The method of claim 1 ,
wherein the paging related configuration information is used to identify a PO associated with the SIM, and
wherein the determination that the PO collision is detected is based on the PO associated with the SIM and a PO associated with a different SIM among the multiple SIMs.
4. A method performed by an access and mobility management function (AMF) entity in a communication system, the method comprising:
receiving, from a user equipment (UE) with multiple subscriber identity modules (SIMs) via a base station of a cell associated with a SIM among the multiple SIMs, a registration request message; and
as a response to the registration request message, transmitting, to the UE via the base station, a registration accept message including adjustment information used to modify a timing of a paging occasion (PO) associated with the SIM,
wherein the registration request message is received based on a determination that a PO collision is detected and a radio resource control (RRC) connection between the UE and the base station established based on a cause value,
wherein the cause value indicates that the UE requests an RRC connection establishment with the base station for an adjustment of the PO associated with the SIM, and
wherein the cell supports the adjustment of the PO associated with the SIM.
5. The method of claim 4 ,
wherein the determination that the PO collision is detected is based on the PO associated with the SIM and a PO associated with a different SIM among the multiple SIMs.
6. A user equipment (UE) in a communication system, the UE comprising:
multiple subscriber identity modules (SIMs);
a transceiver; and
a controller coupled with the transceiver and configured to:
receive, from a base station of a cell associated with a SIM among the multiple SIMs, system information including paging related configuration information, wherein the paging related configuration information includes information whether the cell supports a paging adjustment procedure associated with the SIM,
in case that the cell is identified to support the adjustment, determine whether a PO collision is detected based on the paging related configuration information,
in case that the PO collision is detected, transmit, to the base station, a radio resource control (RRC) setup request message including cause value indicating that the UE requests an RRC connection establishment with the base station for the paging adjustment procedure,
receive, from the base station, an RRC setup message for establishing the RRC connection based on the cause value, and
transmit, to the base station, an RRC setup complete message including a registration request message based on an identification that the PO collision is detected.
7. The UE of claim 6 ,
wherein the controller is further configured to:
receive, from an access and mobility management function (AMF) entity via the base station, a registration accept message, and
wherein the registration accept message includes information used to modify a timing of a paging occasion (PO) associated with the SIM.
8. The UE of claim 6 ,
wherein the paging related configuration information is used to identify a PO associated with the SIM, and
wherein the determination that the PO collision is detected is based on the PO associated with the SIM and a PO associated with a different SIM among the multiple SIMs.
9. An access and mobility management function (AMF) entity in a communication system, the AMF entity comprising:
a transceiver; and
a controller coupled with the transceiver and configured to:
receive, from a user equipment (UE) with multiple subscriber identity modules (SIMs) via a base station of a cell associated with a SIM among the multiple SIMs, a registration request message, and
as a response to the registration request message, transmit, to the UE via the base station, a registration accept message including adjustment information used to modify a timing of a paging occasion (PO) associated with the SIM,
wherein the registration request message is received based on a determination that a PO collision is detected and a radio resource control (RRC) connection between the UE and the base station established based on a cause value,
wherein the cause value indicates that the UE requests an RRC connection establishment with the base station for an adjustment of the PO associated with the SIM, and
wherein the cell supports the adjustment of the PO associated with the SIM.
