Description

Technical Field

[0001] This invention relates to a method and a communication apparatus for a wireless communication system, and particularly to a method and a communication apparatus for processing paging transmissions. Background Technology

[0002] The 3rd Generation Partnership Project (3GPP) developed the Long Term Evolution (LTE) system to improve the Universal Mobile Telecommunications System (UMTS) and support the 3GPP Rel-8 and / or 3GPP Rel-9 standards to meet the increasing needs of users.

[0003] The Advanced Long Term Evolution (LTE-A) system evolved from the Long Term Evolution (LTE-A) system. The goal of the Advanced Long Term Evolution (LTE-A) system is to provide rapid power state transitions, improve edge performance of evolved Node-B (eNB) base stations, and increase peak data rates and throughput. It includes advanced technologies such as carrier aggregation and uplink (UL) multiple-input multiple-output (UL MIMO).

[0004] Next-generation radio access network (NG-RAN) was developed to enhance Advanced Long Term Evolution (LTE) systems, supporting 3GPP Rel-15 to 3GPP Rel-19 standards. NG-RAN comprises one or more next-generation nodes (gNBs) and features such as wider operating frequency bands, different parameter sets (numerologies) across different frequency ranges, massive MIMO (multi-input multi-output) systems, and advanced channel coding.

[0005] Call transmission is performed within a paging frame (PF) of a preset paging cycle (DPC). Because the communication device and network end frequently wake up (e.g., once per preset paging cycle) to perform call transmission, they suffer energy consumption. Therefore, how to handle call transmission to save energy is a pressing issue. Summary of the Invention

[0006] One of the objectives of this invention is to provide a method and communication device thereof for processing call transmission in order to solve the above-mentioned problems.

[0007] This invention discloses a method for processing call transmission in a communication device, comprising: receiving an enhanced paging region (EPR) configuration from a network end, wherein the EPR configuration includes an EPR cycle and a paging monitor window (PMW) configuration; determining at least one paging monitor window in the EPR cycle according to the paging monitor window configuration; receiving at least one downlink (DL) control information (DCI) from the network end in the at least one paging monitor window; and receiving at least one first paging message (PM) from the network end according to the at least one downlink control information.

[0008] The present invention also discloses a communication apparatus for processing call transmission, comprising at least one storage device and at least one processing circuit coupled to the at least one storage device. The at least one storage device is configured to store instructions, and the at least one processing circuit is configured to execute the following instructions stored in the at least one storage device: receiving an enhanced paging region (EPR) configuration from a network end, wherein the EPR configuration includes an EPR cycle and a paging monitor window (PMW) configuration; determining at least one Paging Monitor Window in the EPR cycle based on the Paging Monitor Window configuration; receiving at least one Downlink (DL) control information (DCI) from the network end in the at least one Paging Monitor Window; and receiving at least one first Paging message (PM) from the network end based on the at least one Downlink control information.

[0009] The present invention also discloses a method for processing call transmission at a network end, comprising: transmitting an enhanced paging region (EPR) configuration to a communication device, wherein the EPR configuration includes an enhanced paging region cycle and a paging monitor window (PMW) configuration; transmitting at least one downlink (DL) control information (DCI) to the communication device in at least one preset paging cycle (DPC), wherein the at least one preset paging cycle overlaps with at least one paging monitor window, and the at least one paging monitor window is determined according to the at least one paging monitor window configuration; and transmitting at least one first paging message (PM) to the communication device according to the at least one downlink control information.

[0010] Based on the above description, the present invention provides a method and a communication apparatus for processing call transmission. The communication apparatus determines a call monitoring window based on an enhanced call area configuration transmitted by the network end, and performs call transmission according to the call monitoring window rather than a preset call loop. The network end performs call transmission according to a specific preset call loop associated with the call monitoring window. Therefore, the problem of saving energy in processing call transmission can be solved. Attached Figure Description

[0053] Figure 1 This is a schematic diagram of a wireless communication system 10 according to an embodiment of the present invention, which is simplified to consist of a network terminal 12 and multiple communication devices 14. The wireless communication system 10 can support time-division duplexing (TDD) mode, frequency-division duplexing (FDD) mode, a combined TDD and FDD mode, a non-terrestrial network (NTN) mode, or licensed-assisted access (LAA) mode. That is, the network terminal 12 and the communication devices 14 can communicate with each other through FDD carriers, time-division duplex carriers, licensed carriers (licensed serving cells), and / or unlicensed carriers (or unlicensed serving cells). Furthermore, the wireless communication system 10 can support carrier aggregation. That is, the network terminal 12 and the communication devices 14 can communicate with each other through multiple serving cells (e.g., multiple serving carriers) that include a primary cell (e.g., a primary component carrier) and one or more secondary cells (e.g., secondary component carriers).

[0054] exist Figure 1In this document, network terminal 12 and communication device 14 are used to illustrate the architecture of wireless communication system 10. In a Universal Mobile Telecommunications System (UMTS), network terminal 12 may be a Universal Terrestrial Radio Access Network (UTRAN), which includes at least one base station (Node-B, NB). In one embodiment, in systems such as Long Term Evolution (LTE), LTE-advanced (LTE-A), and evolved versions of LTE, network terminal 12 may be an evolved universal terrestrial radio access network (E-UTRAN), which includes at least one evolved NB (eNB) and / or at least one relay node. In one embodiment, network terminal 12 may be a next-generation radio access network (NG-RAN), which includes at least one next-generation node-B (gNB) and / or at least one fifth-generation (5G) base station (BS). In one embodiment, the next-generation or fifth-generation base station of network terminal 12 may include an non-terrestrial gateway (NTN Gateway) and a non-terrestrial payload (NTN payload). In one embodiment, the next-generation or fifth-generation base station of network terminal 12 may be a transmission reception point (TRP). In one embodiment, network terminal 12 may be any base station conforming to a specific communication standard for communicating with communication device 14.

[0055] New Radio (NR) is a standard defined for fifth-generation systems (or fifth-generation networks) to provide a unified air interface with improved performance. It deploys next-generation base stations to enable fifth-generation systems, supporting advanced features such as enhanced Mobile Broadband (eMBB), Ultra Reliable Low Latency Communications (URLLC), and massive Machine Type Communications (mMTC). EMBB provides broadband service with greater bandwidth and low / medium latency. URLLC offers higher reliability and low latency for applications such as end-to-end communication. Examples of such applications include industrial internet, smart grids, infrastructure protection, remote surgery, and intelligent transportation systems (ITS). MMTC enables the Internet of Things (IoT) of fifth-generation systems, which includes billions of connected devices and / or sensors.

In one embodiment, after network terminal 12 receives information transmitted by communication device 14, the information may be processed only by Universal Terrestrial Global Access Network (UTN / Evolved UTN / Next Generation Radio Access Network), and a decision corresponding to the information may be made by UTN / Evolved UTN / Next Generation Radio Access Network. In one embodiment, UTN / Evolved UTN / Next Generation Radio Access Network may forward the information to the core network, where the core network processes the information and then makes a decision corresponding to the information. In one embodiment, the information may be processed by UTN / Evolved UTN / Next Generation Radio Access Network and the core network, and a decision may be made after coordination and / or cooperation are performed by UTN / Evolved UTN / Next Generation Radio Access Network and the core network.

Furthermore, depending on the transmission direction, network terminal 12 and communication device 14 can be considered as either a transmitter or a receiver. For example, for an uplink (UL), communication device 14 is the transmitter and network terminal 12 is the receiver; for a downlink (DL), network terminal 12 is the transmitter and communication device 14 is the receiver.

The at least one processing circuit 200 can read and execute the program code 214 through the at least one storage device 210. For example, at least one storage device 210 may be a Subscriber Identity Module (SIM), Read-Only Memory (ROM), Flash Memory, Random-Access Memory (RAM), Compact Disc ROM (CD-ROM), Digital Versatile Disc-ROM (DVD-ROM), Blu-ray Disc-ROM (BD-ROM), Magnetic Tape, Hard Disk, Optical Data Storage Device, Non-volatile Storage Device, Non-transitory Computer-readable Medium (e.g., tangible media), etc., but is not limited thereto. At least one communication interface device 220 may include at least one radio transceiver, which is used to transmit and receive signals (e.g., data, information, and / or packets) based on the processing results of at least one processing circuit 200.

[0059] Figure 3 This is a flowchart of process 30 according to an embodiment of the present invention. Process 30 is used in a communication device (e.g., Figure 1 Communication device 14 or Figure 2 The communication device 20 is used to process call transmissions. Process 30 can be compiled into program code 214, which includes the following steps:

[0060] Step 300: Begin.

[0061] Step 302: Receive an enhanced paging region (EPR) configuration from a network end, wherein the enhanced paging region configuration includes an enhanced paging region cycle and a paging monitor window (PMW) configuration.

[0062] Step 304: Based on the call monitoring window configuration, determine at least one call monitoring window in the enhanced call area loop.

[0063] Step 306: In the at least one call monitoring window, receive at least one call downlink (DL) control information (DCI) from the network end.

[0064] Step 308: Receive at least one first call message (paging message, PM) from the network end based on the at least one call downlink control information.

[0065] Step 310: End.

[0066] According to process 30, the communication device receives an enhanced call area configuration from the network. The enhanced call area configuration includes an enhanced call area loop and a call monitoring window configuration. Based on the call monitoring window configuration, the communication device determines at least one call monitoring window within the enhanced call area loop. In the at least one call monitoring window, the communication device receives (e.g., monitors) at least one call downlink control information from the network, and based on the at least one call downlink control information, receives (e.g., monitors) at least one first call information from the network. That is, before receiving (e.g., monitoring) at least one call downlink control information, the communication device identifies at least one call monitoring window. Outside of the at least one call monitoring window in the enhanced call area loop, the communication device disables (e.g., monitors) the reception (e.g., monitoring) of at least one call downlink control information. Therefore, within at least one call monitoring window of a specific radio frame (RF), the communication device performs call transmission to conserve the communication device's energy.

[0067] There are many ways to implement process 30, not limited to those described above. The following examples can be used for process 30.

[0068] In one embodiment, an enhanced call area cycle corresponds to an enhanced call area. In one embodiment, an enhanced call area includes multiple radio frames. In one embodiment, the multiple radio frames include one or more paging frames (PFs). In one embodiment, an enhanced call area includes a starting point of a paging frame. In one embodiment, a call monitoring window (e.g., a call monitoring window of at least one call monitoring window) includes at least one first paging frame.

[0069] In one embodiment, the call monitoring window configuration includes time location information. In one embodiment, the time location information includes a starting point and a length for the call monitoring window. In one embodiment, step 304 includes: based on the time location information, the communication device determines at least one call monitoring window in the enhanced call area loop.

[0070] In one embodiment, the enhanced call zone cycle is a multiple of a preset call cycle. In one embodiment, the call monitoring window configuration includes a call monitoring window indicator indicating at least one preset call cycle. In one embodiment, step 304 includes: based on the call monitoring window indicator, the communication device determines at least one preset call cycle in the enhanced call zone cycle as at least one call monitoring window. In one embodiment, the call monitoring window indicator includes at least one of an index number and a bit map. In one embodiment, the index number indicates at least one preset call cycle. In one embodiment, the bit map includes a plurality of bits. In one embodiment, the plurality of bits respectively correspond to a plurality of preset call cycles in the enhanced call zone cycle. In one embodiment, a bit in the bit map with a first value (e.g., 1) indicates that the corresponding preset call cycle is a call monitoring window. In one embodiment, a bit in the bit map with a second value (e.g., 0) indicates that the corresponding preset call cycle is not a call monitoring window.

[0071] In one embodiment, the communication device receives at least one enhanced call area cyclic parameter from the network end. The at least one enhanced call area cyclic parameter may be included in the enhanced call area configuration. In one embodiment, the communication device determines the indicators based on the at least one enhanced call area cyclic parameter. In one embodiment, the communication device determines the indicators based on equation (Equation 1) or equation (Equation 2). Equation (Equation 1) or equation (Equation 2) is expressed as follows:

[0072] n = QUOTIENT{(SFN mod K),T}+1 (Equation 1)

[0073] n = QUOTIENT{((SFN+offset)mod K),T}+1 (Equation 2)

[0074] Where n is the index, QUOTIENT{·} is the quotient rule, SFN is the index of the wireless frame, offset is the offset used for the call monitoring window, K is the number of wireless frames in the enhanced call zone loop, and T is the number of wireless frames in the preset call loop.

[0075] In one embodiment, according to Equation (Equation 3), the communication device determines at least one second call frame in the call monitoring window (e.g., at least one call monitoring window). Equation (Equation 3) is expressed as follows:

[0076] (SFN+offset)mod T=(T div N)×(ID CD (mod N) (Equation 3)

[0077] Where SFN is the indicator for the wireless frame, offset is the offset used for the call monitoring window, T is the number of wireless frames in the preset call cycle, N is the number of call frames in the preset call cycle, and ID... CD This refers to the identity (ID) of the communication device. In one embodiment, within at least one second call frame in the call monitoring window, the communication device receives (e.g., monitors) call downlink control information (e.g., a call downlink control message of at least one call downlink control message).

[0078] In one embodiment, the call monitoring window configuration includes a coefficient. In one embodiment, step 304 includes: according to equation (Equation 4), the communication device determines at least one first call frame in the enhanced call area loop as a call monitoring window. Equation (Equation 4) is expressed as follows:

[0079] (SFN+offset)mod (m×T)=(T div N)×(ID CD (mod N) (Equation 4)

[0080] Where SFN is the indicator for the wireless communication frame, offset is the offset used for the call monitoring window, m is a coefficient, T is the number of wireless communication frames in the preset call cycle, N is the number of call frames in the preset call cycle, and ID... CDThis refers to the identification of the communication device. That is, when the communication device applies Equation (Equation 4) instead of the legacy Equation (Equation 3) to determine at least one first call frame, the enhanced call area cyclically increases. In one embodiment, in radio frames that do not conform to Equation (Equation 4), the communication device is disabled from receiving (e.g., monitoring) at least one call downlink control information.

[0081] In one embodiment, at least one call downlink control information includes a first resource allocation for SMS and call information (e.g., preset call information). In one embodiment, at least one first call information includes call information. In one embodiment, the call information includes at least one of the following: a paging recordlist (e.g., a preset call recordlist), an extended call recordlist, an additional call recordlist, a first call recordlist indicator for the extended call recordlist, a second call recordlist indicator for the additional call recordlist, and at least one second resource allocation for at least one second call information (e.g., additional call information). In one embodiment, at least one call downlink control information includes at least one second resource allocation for at least one second call information, a first call recordlist indicator for the extended call recordlist, and a second call recordlist indicator for the additional call recordlist. In one embodiment, at least one first call information includes at least one second call information. In one embodiment, at least one second call information includes at least one call recordlist.

[0082] In one embodiment, the SMS message includes at least one of a system information (SI) change indicator and at least one emergency information indicator. In one embodiment, the call log list (e.g., a preset call log list, an extended call log list, and / or an additional call log list) corresponds to at least one communication device that needs to be called by the network. In one embodiment, a first call log list indicator indicates that the call message includes an extended call log list. In one embodiment, the maximum size of the extended call log list is greater than the size of the call log list. In one embodiment, a second call log list indicator indicates that the call message includes an additional call log list. In one embodiment, the maximum size of the additional call log list is not less than the size of the call log list.

[0083] In one embodiment, a communication device is allocated to at least one resource for at least one second call information based on at least one call downlink control information. In another embodiment, a communication device is allocated to at least one resource for at least one second call information based on the call information.

[0084] In one embodiment, during a configured paging opportunity (PO), the communication device monitors at least one call downlink control message. In one embodiment, if the communication device does not receive at least one call downlink control message during the configured paging opportunity, it monitors the call downlink control message during the next paging opportunity. In one embodiment, if the call log list and at least one call log list do not contain the communication device's identification, it monitors the call downlink control message during the next paging opportunity. In one embodiment, if the call information does not contain at least one second resource allocation, it monitors the call downlink control message during the next paging opportunity. In one embodiment, if at least one call log list does not contain the communication device's identification, it monitors the call downlink control message during the next paging opportunity.

[0085] In one embodiment, when a communication device receives at least one call downlink control message during a designated call opportunity, the communication device receives call information and at least one second call information according to a first resource allocation and at least one second resource allocation in the call downlink control message. In another embodiment, when a communication device receives at least one call downlink control message during a designated call opportunity, the communication device receives call information according to a first resource allocation in the call downlink control message. In yet another embodiment, when the call information includes at least one second resource allocation, the communication device receives at least one second call information according to the at least one second resource allocation.

[0086] In one embodiment, the communication device determines whether the call record list in the call information and at least one call record list in at least one second call information contain an identification of the communication device. In one embodiment, the communication device determines whether the call record list in the call information contains an identification of the communication device. In one embodiment, the communication device determines whether the call record list in at least one second call information contains an identification of the communication device.

[0087] In one embodiment, when (for example) the call record list does not contain an identification of the communication device, the communication device determines whether the call information contains at least one second resource allocation.

[0088] In one embodiment, when (e.g.) a call record list and / or at least one call record list contains an identification of a communication device, the communication device performs at least one follow-up operation for the call. In one embodiment, when (e.g.) a call record list contains an identification of a communication device, the communication device performs at least one follow-up operation for the call. In one embodiment, when (e.g.) at least one call record list contains an identification of a communication device, the communication device performs at least one follow-up operation for the call. In one embodiment, the at least one follow-up operation for the call is defined in a communication standard (e.g., the 3rd Generation Partnership Project standard).

[0089] In one embodiment, the enhanced call area configuration further includes a first state indicator (e.g., a network energy savings paging (NES-P) indicator) indicating the initial state of the enhanced call area configuration. In one embodiment, based on the initial state, the communication device determines whether to apply the enhanced call area configuration (e.g., whether to execute steps 304, 306, and 308 of process 30). For example, the communication device applies the enhanced call area configuration in response to an initial state that is active. For example, the communication device disables the application of the enhanced call area configuration in response to an initial state that is deactivate. In one embodiment, the communication device stores the enhanced call area configuration in response to an initial state that is deactivate.

[0090] In one embodiment, the communication device receives a second status indicator (e.g., a network energy-saving call indicator) from a network end for enhanced call area configuration to activate or deactivate the enhanced call area configuration. For example, after receiving the second status indicator indicating an activated state, the communication device activates and applies the enhanced call area configuration. For example, after receiving the second status indicator indicating a deactivated state, the communication device deactivates and disables the application of the enhanced call area configuration. In one embodiment, after receiving the second status indicator indicating a deactivated state, the communication device performs a conventional (or normal) call. In one embodiment, at least one of at least one call downlink control message, at least one first call message, and system information includes the second status indicator.

[0091] In one embodiment, the communication device receives barring information (e.g., a Network Energy Saving Call Allowing bit) from the network. In one embodiment, the barring information indicates whether a cell at the network end supports network energy saving calls. In one embodiment, the barring information is contained in the master information block (MIB) or system information block type 1 (SIB1). In one embodiment, a communication device that supports network energy saving calls can camp on the cell in response to the barring information indicating that the cell supports network energy saving calls. In one embodiment, a communication device that does not support network energy saving calls cannot camp on the cell in response to the barring information indicating that the cell supports network energy saving calls.

[0092] Figure 4 This is a flowchart of process 40 according to an embodiment of the present invention. Process 40 is used in a network terminal (e.g., Figure 1 Network terminal 12 or Figure 2 The communication device 20 is used to process call transmissions. Process 40 can be compiled into program code 214, which includes the following steps:

[0093] Step 400: Begin.

[0094] Step 402: Transmit an enhanced call zone configuration to a communication device, wherein the enhanced call zone configuration includes an enhanced call zone loop and a call monitoring window configuration.

[0095] Step 404: In at least one preset call loop, at least one call downlink control information is transmitted to the communication device, wherein the at least one preset call loop overlaps with at least one call monitoring window, and the at least one call monitoring window is determined according to the configuration of the at least one call monitoring window.

[0096] Step 406: Based on the at least one call downlink control information, transmit at least one first call information to the communication device.

[0097] Step 408: End.

[0098] According to process 40, the network end transmits enhanced call area configuration to the communication device. The enhanced call area configuration includes enhanced call area loop and call monitoring window configuration. In at least one preset call loop, the network end transmits at least one call downlink control message to the communication device. The at least one preset call loop overlaps with at least one call monitoring window (e.g., completely or partially), and the at least one call monitoring window is determined based on the at least one call monitoring window configuration. Based on the at least one call downlink control message, the network end transmits at least one first call message to the communication device. That is, in a specific preset call loop, the network end transmits at least one call downlink control message. Therefore, energy savings can be achieved at the network end.

[0099] There are many ways to implement process 40, not limited to those described above. The following examples can be used for process 40.

[0107] In one embodiment, the SMS message includes at least one of a system information change indicator and at least one emergency information indicator. In one embodiment, the call log list (e.g., a preset call log list, an extended call log list, and / or an additional call log list) corresponds to at least one communication device that needs to be called by the network. In one embodiment, a first call log list indicator indicates that the call message includes an extended call log list.

[0139] Figure 13 This is a timing diagram of process 130 in Embodiment 1 of the present invention. Figure 13In this process, the communication device CM and the network terminal NW are used to process call transmission. In step 1300, the communication device CM receives an Enhanced Call Area Configuration (EPR_Config) with a status indicator SI1 (e.g., a first status indicator for the embodiment of process 30) from the network terminal NW, wherein the status indicator SI1 indicates that the initial state of the Enhanced Call Area Configuration (EPR_Config) is off. In step 1302, based on the status indicator SI1, the communication device CM stores the Enhanced Call Area Configuration (EPR_Config).

[0140] Figure 14 This is a timing diagram of process 140 in Embodiment 1 of the present invention. Figure 14In this process, the communication device CM and the network terminal NW are used to process call transmission. In step 1400, the communication device CM receives an Enhanced Call Area Configuration (EPR_Config) with a status indicator SI1 (e.g., a first status indicator for the embodiment of process 30) from the network terminal NW, where the status indicator SI1 indicates that the initial state of the Enhanced Call Area Configuration (EPR_Config) is off. In step 1402, the communication device CM stores the Enhanced Call Area Configuration (EPR_Config) according to the status indicator SI1. In step 1404, the network terminal NW transmits call information PM1 or call downlink control information P_DCI1 with a status indicator SI2 to the communication device CM, but the communication device CM does not (e.g., successfully) receive the call information PM1 or the call downlink control information P_DCI1. The status indicator SI2 indicates an enabled state. In step 1406, the network terminal NW changes the initial state of the Enhanced Call Area Configuration (EPR_Config). In step 1408, the communication device CM receives system information SIF with status indicator SI3 from the network end NW, where status indicator SI3 indicates an enabled state. In step 1410, based on status indicator SI3, the communication device CM enables and applies the enhanced call area configuration EPR_Config. In step 1412, the communication device CM receives call information PM2 or call downlink control information P_DCI2 with status indicator SI4 from the network end NW, where status indicator SI4 indicates a disabled state.

[0141] Figure 15 This is a schematic diagram of a relationship 150 between a preset call loop and a call monitoring window in Embodiment 1 of the present invention. Figure 15 In the diagram, the horizontal axis represents the time domain T. Radio frames 1500 for communication devices are grouped into Enhanced Call Area Cycles (EPR_C1 to EPR_C2), and radio frames 1510 for the network are grouped into Preset Call Cycles (DPC1 to DPC4). The length of the call monitoring window is less than the length of the preset call cycle. Enhanced Call Area Cycle (EPR_C1) includes a call monitoring window (PMW1) for monitoring call downlink control information for the communication device. In other radio frames of Enhanced Call Area Cycle (EPR_C1) (represented by slashed boxes), the communication device can enter an idle mode or an inactive mode. Enhanced Call Area Cycle (EPR_C2) is similar to Enhanced Call Area Cycle (EPR_C1) and will not be described further here.

[0142] exist Figure 15 In the preset call loop DPC1, since the starting point overlaps with the call monitoring window PMW1, the network terminal calls the communication device within the preset call loop DPC1. Since the starting point of the preset call loop DPC2 does not overlap with the call monitoring windows PMW1-PMW2, the network terminal is disabled from calling the communication device within the preset call loop DPC2. Since the starting point of the preset call loop DPC3 overlaps with the call monitoring window PMW2, the network terminal calls the communication device within the preset call loop DPC3. Since the starting point of the preset call loop DPC4 does not overlap with the call monitoring windows PMW1-PMW2, the network terminal is disabled from calling the communication device within the preset call loop DPC4. Therefore, within the preset call loops DPC2 and DPC4, the network terminal can enter an idle mode or an inactive mode.

[0143] Figure 16 This is a schematic diagram of a relationship 160 between a preset call loop and a call monitoring window in Embodiment 1 of the present invention. Figure 16 In the diagram, the horizontal axis represents the time domain T. The radio frames 1600 for the communication device are grouped into Enhanced Call Area Cycles (EPR_C1) to EPR_C2, and the radio frames 1610 for the network are grouped into Preset Call Cycles (DPC1) to DPC13. The length of the call monitoring window is greater than the length of the preset call cycle. Enhanced Call Area Cycle (EPR_C1) includes a call monitoring window (PMW1) for the communication device to monitor call downlink control information. In other radio frames of Enhanced Call Area Cycle (EPR_C1) (represented by slashed boxes), the communication device can enter an idle mode or an inactive mode. Enhanced Call Area Cycle (EPR_C2) is similar to Enhanced Call Area Cycle (EPR_C1) and will not be described further here.

[0144] exist Figure 16 In this scenario, because the starting point of the preset call loop DPC2 is the starting point of the first preset call loop in the call monitoring window PMW1, the network terminal calls the communication device within preset call loop DPC2. Similarly, because the starting point of the preset call loop DPC8 is the starting point of the first preset call loop in the call monitoring window PMW2, the network terminal calls the communication device within preset call loop DPC8. Since the starting points of preset call loops DPC1, DPC3-DPC7, and DPC9-DPC13 are not the starting points of the first preset call loop in the call monitoring windows PMW1-PMW2, the network terminal is disabled from calling the communication device within preset call loops DPC1, DPC3-DPC7, and DPC9-DPC13. Therefore, within preset call loops DPC1, DPC3-DPC7, and DPC9-DPC13, the network terminal can enter idle or inactive mode.
