Detailed Description
When the terminal equipment is in an idle state, the network side needs to interact with the terminal, and the network can inform the terminal equipment through paging. Therefore, the terminal device needs to monitor the paging message (paging) to be able to complete the subsequent response. If the terminal device always monitors the paging message in the idle state, energy consumption is wasted, and therefore, in order to save energy consumption, the terminal selects a paging cycle according to parameters configured on the network side and monitors the paging message in the paging cycle.
The terminal device may select the paging cycle among three cycles:
default period, non-access stratum configuration period and radio resource control layer configuration period.
The default period is issued by a network side to a terminal device through a Radio Resource Management (RRM) message, and may be specifically configured in an SIB1 (systemlnformationblock 1, system information block 1).
The Non-access stratum (NAS) configuration period is obtained and issued by a higher layer negotiation when the terminal has a need, and specifically, the Non-access stratum (NAS) configuration period may be configured through NAS signaling.
A Radio Resource Control (RRC) layer configuration cycle is configured when RRC is released, and specifically may be configured through RRC signaling.
When the terminal equipment is in an idle (idle) state, the minimum value of a default period and a non-access stratum configuration period can be used as a paging period; when the terminal device is in an INACTIVE (INACTIVE) state, the minimum value of the default period, the non-access stratum configuration period, and the radio resource control layer configuration period may be used as the paging period.
The default period configured by the network side is for all terminal devices, and therefore, cannot be configured too much, which results in that, when the paging period is determined in the above manner, even if the terminal negotiates a larger period with the network, the smaller default period is finally used as the paging period.
For example, in some scenarios, the terminal device does not need to frequently detect the paging message, and the terminal device sleeps for a long time, and in this case, the terminal device does not need to frequently detect the paging message, but a smaller default period is configured on the network side, so that the terminal device does not take effect even if the terminal device negotiates with the network for a longer period, and further the terminal device frequently detects redundant paging messages, and the problem that the energy consumption of the terminal device cannot be effectively saved is caused.
According to the scheme provided by the application, the terminal equipment does not directly take the configured minimum period as the paging period, but determines the paging period according to the communication state and the configuration period of the terminal equipment.
Fig. 1 is a diagram illustrating an application scenario according to an exemplary embodiment of the present application.
As shown in fig. 1, in a communication application scenario, a terminal device 11 may be included, and the terminal device 11 is connected to a network through a wireless signal, where the network includes at least one network device 12.
Wherein, the network device 12 may send an indication message to the terminal device 11 for periodic configuration. One of the network devices 12 may send an instruction message to the terminal device 11, or a plurality of network devices 12 may send instruction messages to the terminal device 11, respectively, and further configure a plurality of cycles.
In particular, one of the network devices 12 may be a radio resource management device, which may configure a default period of the terminal device through SIB 1. One of the network devices 12 may also be a non-access stratum device, and after the terminal device 11 negotiates with a non-access stratum network, the non-access stratum device may issue a non-access stratum signaling to the terminal device to configure a specific period. One of the network devices 12 may also be a radio resource control layer device, and when the radio resource control layer connection is released, the radio resource control layer device may issue a radio resource control layer signaling to the terminal device 11, and configure another specific period.
Further, the terminal device may determine the paging cycle in the cycle configured by the network device based on the scheme provided in this application.
Fig. 2 is a flowchart illustrating a method for determining a paging cycle according to an exemplary embodiment of the present application.
The method provided by the application can be applied to terminal equipment, and the terminal equipment can be equipment which can be accessed into a wireless communication network, such as a mobile phone, internet of things equipment and the like. The terminal device may also be the terminal device 11 shown in fig. 1.
The method for determining the paging cycle provided by the embodiment includes:
step 201, at least one indication message sent by a network device is received, where the indication message is used to indicate a configuration cycle.
The terminal device may receive the indication information sent by the network device, and the terminal device may configure the period according to the indication information, and specifically may determine the corresponding period according to the configuration parameters in the indication information. The network device is not limited to a network device in a communication system, and different network devices can transmit different indication messages to the terminal device.
Specifically, the terminal device may receive at least one indication message sent by the network device, for example, receive an indication message sent by the radio resource management device, may also receive an indication message sent by a non-access stratum device, and may also receive an indication message sent by a radio resource control layer device. For different indication messages, the terminal device may determine a corresponding period according to the configuration parameters therein.
Different indication messages may be used to indicate different configuration periods, for example, if the indication message is SIB1 issued by the radio resource management device, the indication message is used to configure a default period of the terminal device. If the indication message is a signaling sent by the non-access stratum equipment after the terminal equipment negotiates with the non-access stratum network, the indication message is used for configuring a non-access stratum configuration period of the terminal equipment. If the indication message is a signaling issued by the radio resource control layer device when the connection of the radio resource control layer is released, the indication message is used for configuring the radio resource control layer configuration cycle of the terminal device.
Step 202, determining a paging cycle according to the communication state and the configuration cycle of the terminal device.
In practical application, the terminal device may obtain its own communication state, and determine the paging cycle in combination with the configuration cycle indicated by the indication message. For example, the terminal device may use one of the configuration periods as a paging period according to the communication state and the configuration period.
The communication state of the terminal device may include an idle state and an inactive state. The terminal device can select an available configuration period from the configuration periods according to the communication state, and then determine the paging period from the available configuration periods.
For example, when the terminal device is in an idle state, the paging cycle may be determined in a default period, a non-access stratum configuration period. When the terminal device is in the inactive state, the paging cycle may be determined in a default cycle, a non-access stratum configuration cycle, and a radio resource control layer configuration cycle.
Specifically, the network side generally configures a smaller default period for the terminal device. In the scheme of the application, when the paging cycle is determined, the non-access stratum configuration cycle can be used as a reference cycle, and the paging cycle can be determined according to the size of the non-access stratum configuration cycle.
For example, a preset value may be set, and if the period of non-access stratum configuration is less than or equal to the preset value, it may be considered that the terminal device negotiates with the network for a smaller special period. In this case, it may be considered that the terminal device needs to frequently monitor the paging message, and therefore, the smallest period among the plurality of configuration periods may be used as the paging period. The preset value may be notified to the terminal by the network in the form of a system broadcast message, for example, the network device of the access layer may send a system broadcast message to the terminal device to notify the terminal device of the size of the preset value. Furthermore, the preset value may also be determined by the terminal in the form of a predefined value. For example, when the non-access stratum configuration period is smaller than the preset value, if the terminal device is in the idle state, the minimum value of the default period and the non-access stratum configuration period may be determined as the paging period. If the terminal device is in the inactive state, the minimum value of the default period, the non-access stratum configuration period, and the radio resource control layer configuration period may be determined as the paging period.
If the non-access stratum configuration period is greater than the preset value, it can be considered that the terminal device negotiates with the network for a larger special period. In this case, it may be considered that the terminal device does not need to frequently monitor the paging message, and may sleep for a long time, and at this time, a smaller default period configured on the network side may not be considered.
For example, when the non-access stratum configuration period is greater than the preset value, if the terminal device is in the idle state, the non-access stratum configuration period may be determined as the paging period. If the terminal device is in the inactive state, the minimum value of the configuration period of the non-access stratum and the configuration period of the radio resource control layer can be determined as the initial paging period.
Optionally, when the non-access stratum configuration period is less than or equal to the preset value, the maximum value or the intermediate value in the multiple configuration periods may be used as the paging period. For example, when the terminal device is in the idle state, the maximum value of the default period and the non-access stratum configuration period may be determined as the paging period. When the terminal device is in the inactive state, the intermediate value or the maximum value may be determined as the paging cycle in a default cycle, a non-access stratum configuration cycle, or a radio resource control layer configuration cycle.
In the embodiment, the interval of the paging detection of the terminal equipment is larger, and the energy consumption of the terminal equipment can be effectively saved.
In an exceptional case, if the configuration period is defined as an invalid value or is not within a defined range of values, the value may be considered to not satisfy the preset condition, and the invalid value does not participate in the selection process of the configuration period.
In the method provided by the application, the terminal device determines the paging cycle according to the communication state and the configuration cycle configured for the terminal device by the network side, rather than directly taking the minimum cycle in the cycle configured by the network as the paging cycle, so that a smaller default cycle can be avoided as the paging cycle under the condition that the terminal device does not need to frequently monitor the paging message, and the energy consumption of the terminal device can be further saved.
Specifically, after the paging cycle is determined, the terminal device may further determine the paging time according to the paging cycle. Specifically, a paging frame may be determined in a paging cycle, and then a paging subframe may be determined in the paging frame, and the terminal device may monitor whether the paging subframe includes a paging message.
The method provided by the present application is used for determining a paging cycle, and is performed by a device provided with the method provided by the present embodiment, and the device is generally implemented in a hardware and/or software manner.
The method for determining the paging cycle is applied to terminal equipment and comprises the following steps: receiving at least one indication message, wherein the indication message is used for indicating a configuration period; and determining a paging cycle according to the communication state and the configuration cycle of the terminal equipment. In the method, the terminal device determines the paging cycle according to the communication state and the configuration cycle configured for the terminal device by the network side, so that a smaller default cycle can be avoided as the paging cycle under the condition that the terminal device does not need to monitor the paging message frequently, and the energy consumption of the terminal device can be further saved.
In an alternative embodiment, the configuration cycle includes at least one of: a default period, a non-access stratum configuration period and a radio resource control layer configuration period.
Different indication messages may be used to indicate different configuration periods, which may include at least one of:
and a non-access layer configuration period, wherein the paging period is determined in a default period, a non-access layer configuration period and a radio resource control layer configuration period.
For example, if the indication message is SIB1 delivered by the radio resource management device, the indication message is used to configure a default period of the terminal device. If the indication message is a signaling sent by the non-access stratum equipment after the negotiation of the terminal equipment and the non-access stratum network, the indication message is used for configuring a non-access stratum configuration period of the terminal equipment. If the indication message is a signaling issued by the radio resource control layer device when the radio resource control layer connection is released, the indication message is used for configuring a radio resource control layer configuration cycle of the terminal device.
In an optional embodiment, the indication message may include a non-access stratum configuration parameter. For example, the network device may issue the non-access stratum configuration parameters through negotiation between the terminal device and the network. The non-access stratum configuration parameter may include indication information, where the indication information is used to indicate that a non-access stratum configuration period is used as a paging period.
Wherein, the embodiment is suitable for the terminal device in idle state or inactive state.
The terminal device may read the non-access stratum configuration parameter, and when the non-access stratum configuration parameter includes the indication information, the non-access stratum configuration period may be directly used as the paging period.
In one embodiment, the non-access stratum configuration parameter includes a discontinuous reception parameter, and the terminal device may determine whether to include the indication information according to a specific value in the discontinuous reception parameter. For example, the 8 th bit of the DRX value in the discontinuous reception parameter may be used as an indication information bit, and if the 8 th bit of the DRX value is 1, it is considered that the non-access stratum configuration parameter includes the indication information, and the terminal device may use the non-access stratum configuration cycle as the paging cycle.
In this embodiment, whether to directly use the present configuration as a paging cycle may be indicated by a 8 th bit of the DRX value.
In an optional embodiment, the indication message may include radio resource control layer configuration parameters. For example, when the connection of the radio resource control layer is released, the radio resource control layer device may issue the configuration parameters of the radio resource control layer to the terminal device. The configuration parameter of the radio resource control layer may include indication information, where the indication information is used to indicate that the radio resource control layer configuration cycle is used as a paging cycle.
Wherein, the embodiment is suitable for the terminal device in the non-activated state.
The terminal device can read the configuration parameter of the radio resource control layer, and when the configuration parameter of the radio resource control layer includes the indication information, the configuration cycle of the radio resource control layer can be directly used as the paging cycle.
In one embodiment, an indication information bit may be set in the configuration parameter of the radio resource control layer, for example, an enableclycle is added, and when the value of the enableclycle is 1, the terminal device uses the configuration cycle of the radio resource control layer as a paging cycle.
In this embodiment, it may be indicated by enablelcycle whether to directly use the present configuration as a paging cycle.
In an alternative embodiment, the indication message may include non-access stratum configuration parameters. For example, the network device may issue the non-access stratum configuration parameters through negotiation between the terminal device and the network. The terminal device may determine a corresponding non-access stratum configuration period according to the non-access stratum configuration parameter.
For example, the non-access stratum configuration parameters include discontinuous reception parameters, and the terminal device may determine the non-access stratum configuration period according to specific values in the discontinuous reception parameters. The terminal device may read the DRX value in the discontinuous reception parameter, and determine the non-access stratum configuration period according to the read value.
In one embodiment, the non-access stratum configuration period may be determined using a low four-bit encoding of DRX value. The method specifically comprises the following steps: when the low four-bit code of the DRX value is 0000, the non-access stratum configuration period is not set; when the lower four bits of DRX value are coded to be 0001, the configuration period of the non-access stratum is 32; when the low four-bit code of the DRX value is 0010, the non-access stratum configuration period is 64; when the low four-bit code of the DRX value is 0011, the non-access stratum configuration period is 128; when the low four-bit code of the DRX value is 0100, the configuration cycle of the non-access stratum is 256; when the low four-bit code of the DRX value is 0110, the non-access stratum configuration period is 512; when the low four-digit code of the DRX value is 0111, the configuration period of the non-access stratum is 1024; when the lower four bits of DRX value are encoded to 1000, the non-access stratum configuration period is 2048.
In another embodiment, the non-access stratum configuration period can also be determined by using the 1 st-7 th bit code of the DRX value. For example, the period value is determined by using the 1 st to 4 th bit codes, the multiplying factor value is determined by using the 5 th to 7 th bits, and the product of the period value and the multiplying factor value is used as the non-access stratum configuration period. For example, the magnification is 4 for the 5 th to 7 th coded bits 001 and 8 for the 5 th to 7 th coded bits 010. The manner of determining the period value using the 1 st to 4 th bit codes is similar to the previous embodiment. The method specifically comprises the following steps: when the 1 st to 7 th bits of the DRX value are coded to 0000000, a non-access stratum configuration period is not set; when the 1 st to 7 th bit codes of the DRX value are 0010001, the non access stratum configuration period is 32 x 4; when the 1 st to 7 th bits of the DRX value are coded to 0100010, the non-access stratum configuration period is 64 × 8; when the 1 st to 7 th bits of the DRX value are encoded to 0100011, the non access stratum configuration period is 128 × 8; when the 1 st-7 th bits of DRX value are encoded to 0100100100, the non access stratum configuration period is 256 × 8.
In an optional implementation manner, if the communication state of the terminal device is an idle (idle) state and the non-access stratum configuration period is less than or equal to a first preset value, the paging period is a minimum value or a maximum value of a default period and the non-access stratum configuration period.
If the communication state is the idle state, the paging cycle may be determined according to a default cycle configured for the terminal device by the network and a non-access stratum configuration cycle.
In one embodiment, if the communication state is an idle state and the period of non-access stratum configuration is less than or equal to the first preset value, it may be considered that the terminal and the network negotiate to obtain a smaller special period, and therefore, the terminal device does not need to sleep for a long time and needs to monitor the paging message frequently. In this case, the paging cycle may be set to the minimum value of the default cycle and the non-access stratum configuration cycle, so as to avoid that the monitoring message is not timely due to an excessively large paging cycle.
In another embodiment, if the communication state is an idle state and the non-access stratum configuration period is less than or equal to the first preset value, it may be considered that the terminal and the network negotiate to obtain a smaller special period, and at this time, the paging period may be a maximum value of a default period and the non-access stratum configuration period. Generally, the network side indicates a smaller default period to the terminal device, and the network side indicates a smaller non-access stratum configuration period to the terminal device, that is, the values of the two periods are smaller, and no matter which period is used as the paging period, the interval for detecting the paging message is not very long, so that a larger value can be selected as the paging period, and the energy consumption of the terminal device is saved.
Further, the first preset value may be set according to requirements, and may be 256, for example.
In an optional implementation manner, if the communication state of the terminal device is an idle (idle) state and the non-access stratum configuration period is greater than the first preset value, the paging cycle is the non-access stratum configuration period of the terminal device.
If the communication state is the idle state, the paging cycle may be determined according to a default cycle configured for the terminal device by the network and a non-access stratum configuration cycle.
Specifically, if the communication state is an idle state and the non-access stratum configuration period is greater than the first preset value, it may be considered that the terminal negotiates with the network to obtain a larger special period, and therefore, the terminal device needs to sleep for a long time and does not need to monitor the paging message frequently. In this case, the paging cycle may be set as a non-access stratum configuration cycle of the terminal device, so as to avoid that a smaller default cycle of network configuration is used as the paging cycle, which results in an excessively short paging cycle and causes unnecessary monitoring of paging messages, thereby reducing energy consumption of the terminal device.
Further, the first preset value may be set according to a requirement, and may be 256, for example.
In an optional implementation manner, if the communication state of the terminal device is an inactive (inactive) state and the non-access stratum configuration period is less than or equal to the second preset value, the paging period is any one of a minimum value, a middle value and a maximum value in a default period, the non-access stratum configuration period and a radio resource control layer configuration period.
If the communication state is an inactive (inactive) state, the paging cycle may be determined according to a default cycle configured for the terminal device by the network, a non-access stratum configuration cycle, and a radio resource control layer configuration cycle.
In one embodiment, if the communication state is an inactive state and the period of non-access stratum configuration is less than the second preset value, it may be considered that the terminal and the network negotiate to obtain a smaller special period, and therefore, the terminal device does not need to sleep for a long time and needs to monitor the paging message frequently. In this case, the paging cycle may be set to the minimum value of the default cycle, the non-access stratum configuration cycle, and the radio resource control layer configuration cycle, so as to avoid that the monitoring message is not timely due to an excessively large paging cycle.
In another embodiment, if the communication state is an inactive state and the non-access stratum configuration period is less than or equal to the second preset value, it may be considered that the terminal and the network negotiate to obtain a smaller special period, and at this time, the paging period may be an intermediate value among a default period, the non-access stratum configuration period, and a radio resource control layer configuration period. Generally, the network side indicates a smaller default period to the terminal device, and the network side indicates a smaller non-access stratum configuration period to the terminal device, that is, in three configuration periods of the terminal device, at least two configuration period values are smaller, then the middle value in the three configuration periods is also a smaller value, the middle value is taken as a paging period, and the interval of the terminal device in detecting the paging message is not very long, so that a middle value can be selected as the paging period, thereby saving the energy consumption of the terminal device.
In another embodiment, if the communication state is an inactive state and the non-access stratum configuration period is less than or equal to the second preset value, it may be considered that the terminal and the network negotiate to obtain a smaller special period, and at this time, the paging period may be a maximum value among a default period, the non-access stratum configuration period, and a radio resource control layer configuration period. The maximum value of the three periods is taken as the paging period, so that the energy consumption of the terminal equipment is effectively saved. This approach may be applied, for example, in application scenarios where terminal power consumption is particularly to be conserved. Further, the second preset value may be set according to requirements, and may be 256, for example.
In an optional implementation manner, if the communication state of the terminal device is an inactive (inactive) state and the nas configuration cycle is greater than the second preset value, the paging cycle is a minimum value or a maximum value of the nas configuration cycle and the rrc configuration cycle.
If the communication state is the inactive state, the paging cycle may be determined according to a default cycle configured for the terminal device by the network, a non-access stratum configuration cycle, and a radio resource control stratum configuration cycle.
In one embodiment, if the communication state is an inactive state and the period of non-access stratum configuration is greater than the second preset value, it may be considered that the terminal negotiates with the network for a longer special period, and therefore, the terminal device needs to sleep for a long time and does not need to monitor the paging message frequently. In this case, the paging cycle may be set to the minimum value of the non-access stratum configuration cycle and the radio resource control layer configuration cycle, so as to avoid that a smaller default cycle configured by the network is used as the paging cycle, which results in an excessively short paging cycle and leads to unnecessary monitoring of the paging message, thereby reducing the energy consumption of the terminal device.
In another embodiment, if the communication state is an idle state and the non-access stratum configuration period is greater than the second preset value, it may be considered that the terminal and the network negotiate to obtain a larger special period, and at this time, the paging period may be a maximum value of the non-access stratum configuration period and the radio resource control layer configuration period. In general, a network side will indicate a smaller default period to a terminal device, and the terminal device will use the smaller default period as a paging period, which results in that the energy consumption of the terminal device cannot be effectively saved. According to the method, the maximum value in the configuration period of the non-access layer and the configuration period of the radio resource control layer can be used as the paging period, so that unnecessary paging message monitoring of the terminal equipment is avoided, and the energy consumption of the terminal equipment is reduced.
Further, the second preset value may be set according to a requirement, and may be 256, for example.
In an optional implementation manner, if the communication state of the terminal device is an inactive (inactive) state and the radio resource control layer configuration period is less than or equal to the second preset value, the paging period is any one of a default period, a non-access stratum configuration period, a minimum value, a middle value, and a maximum value in the radio resource control layer configuration period.
If the communication state is an inactive (inactive) state, the paging cycle may be determined according to a default cycle, a non-access stratum configuration cycle, and a radio resource control layer configuration cycle configured for the terminal device by the network.
In one embodiment, if the communication state is an inactive state and the radio resource control layer configuration period is less than or equal to the second preset value, it may be considered that the network configures a smaller special period for the terminal device, and therefore, the terminal device does not need to sleep for a long time and needs to monitor the paging message frequently. In this case, the paging cycle may be set to the minimum value of the default cycle, the non-access stratum configuration cycle, and the radio resource control layer configuration cycle, so as to avoid that the monitoring message is not timely due to an excessively large paging cycle.
In another embodiment, if the communication state is an inactive state and the radio resource control layer configuration period is less than or equal to the second preset value, it may be considered that the terminal and the network negotiate to obtain a smaller special period, and at this time, the paging period may be an intermediate value among a default period, a non-access stratum configuration period, and a radio resource control layer configuration period. Generally, the network side indicates a smaller default period to the terminal device, and the network side indicates a smaller radio resource control layer configuration period to the terminal device, that is, in three configuration periods of the terminal device, at least two configuration period values are smaller, then an intermediate value in the three configuration periods is also a smaller value, the intermediate value is used as a paging period, and an interval for detecting a paging message by the terminal device is not very long, so that an intermediate value can be selected as the paging period, thereby saving energy consumption of the terminal device.
In another embodiment, if the communication state is an inactive state and the radio resource control layer configuration period is less than or equal to the second preset value, it may be considered that the terminal device and the network negotiate to obtain a smaller special period, and at this time, the paging period may be a maximum value among a default period, a non-access layer configuration period, and a radio resource control layer configuration period. The maximum value of the three periods is taken as the paging period, so that the energy consumption of the terminal equipment is effectively saved. This approach may be applied, for example, in application scenarios where it is particularly desirable to conserve terminal power consumption.
Further, the second preset value may be set according to a requirement, and may be 256, for example.
In an optional implementation manner, if the communication state of the terminal device is an inactive (inactive) state and the radio resource control layer configuration cycle is greater than the second preset value, the paging cycle is a minimum value or a maximum value of the non-access stratum configuration cycle and the radio resource control layer configuration cycle.
If the communication state is the inactive state, the paging cycle may be determined according to a default cycle, a non-access stratum configuration cycle, and a radio resource control layer configuration cycle configured for the terminal device by the network.
In one embodiment, if the communication state is an inactive state and the radio resource control layer configuration period is greater than the second preset value, it may be considered that the network configures a larger special period for the terminal device, and therefore, the terminal device needs to sleep for a long time and does not need to monitor the paging message frequently. In this case, the paging cycle may be set to the minimum value of the non-access stratum configuration cycle and the radio resource control layer configuration cycle of the terminal device, so as to avoid that a smaller default cycle configured by the network is used as the paging cycle, which results in an excessively short paging cycle and causes unnecessary monitoring of the paging message, thereby reducing the energy consumption of the terminal device.
In another embodiment, if the communication state is an idle state and the radio resource control layer configuration period is greater than the second preset value, it may be considered that the terminal and the network negotiate to obtain a larger special period, and at this time, the paging period may be a maximum value of a non-access stratum configuration period and a radio resource control layer configuration period. In general, a network side will indicate a smaller default period to a terminal device, and the terminal device will use the smaller default period as a paging period, which results in that the energy consumption of the terminal device cannot be effectively saved. According to the method, the maximum value in the configuration period of the non-access stratum and the configuration period of the radio resource control layer can be used as the paging period, so that the terminal equipment is prevented from monitoring meaningless paging messages, and the energy consumption of the terminal equipment is further reduced.
Further, the second preset value may be set according to requirements, and may be 256, for example.
Fig. 3 is a flowchart illustrating a method for determining a paging cycle according to another exemplary embodiment of the present application.
As shown in fig. 3, the method for determining a paging cycle provided in the present application includes:
step 301, at least one indication message is received, wherein the indication message is used for indicating a configuration cycle.
Step 302, determining a paging cycle according to the communication state and the configuration cycle of the terminal device.
Steps 301 and 302 are similar to the embodiment shown in fig. 2, and the paging cycle may be determined according to any of the above embodiments.
Step 303, determining a paging time according to the paging cycle.
In the method provided in this embodiment, after determining the Paging cycle, the terminal device may also determine a Paging Occasion (PO) according to the Paging cycle, and further monitor the Paging message based on the Paging Occasion.
Specifically, a Paging Frame (PF) number and a corresponding subframe number may be obtained in a Paging cycle, and a Paging time is a subframe or a corresponding slot or a corresponding symbol corresponding to the subframe number in a data Frame corresponding to the Paging Frame number.
The Paging Frame (PF) number for monitoring the Paging message may be determined in the Paging cycle, and then the Paging time may be determined in the Paging Frame, that is, the subframe, slot, or symbol of the Paging message may be included.
Specifically, the paging frame number may be determined according to the following equation:
(SFN+PF_offset)mod T＝(T div N)*(UE_ID mod N)
wherein T is the determined paging cycle.
N is the number of paging frames included in one paging cycle. Wherein, N is configured by a network, and can be configured by a system broadcast message, for example, configured by a nAndPaginFrameOffset parameter, and can currently take values of T, T/2, T/4, T/8, T/16. In combination with the expansion of the period itself, the value of N also needs to be expanded to T/32, T/64, T/128, T/256 values.
PF _ offset is the paging frame offset.
The UE _ ID is a preset user identification and is obtained through calculation of an IMSI module 1024.
Further, the product of the quotient of the paging cycle divided by the number of paging frames (T div N) and the remainder of the division of the predetermined user ID by the number of final paging frames (UE _ ID mod N) is equal to the remainder of the division of the paging cycle by the configured offset of the paging frame number ((SFN + PF _ offset) mod T).
In practical application, the SFN, i.e. the frame number of the paging frame, can be obtained based on the above formula.
Wherein the subframe number may also be determined according to:
i_s＝floor(UE_ID/N)mod Ns。
where Ns is the number of paging subframes included in one paging frame, and a value of Ns may be read from the SIB1 message, for example, may be a value of 1, 2, 4, or the like.
i _ s is the paging identity of the user terminal. The paging identifier of the UE can be obtained by using the ratio (UE _ ID/N) of the preset UE identifier to the number of paging frames and then taking the rest of the ratio with the number of paging subframes (Ns).
Specifically, a frame number corresponding to a combination of the paging identifier (i _ s) and the number of paging subframes (Ns) of the user terminal may be set in advance. The terminal equipment can look up a table according to the i _ s and the Ns to obtain a corresponding frame number, and the frame number is the subframe number.
Further, the terminal device may use a subframe corresponding to a subframe number in a data frame corresponding to the paging frame number as the paging occasion. For example, the 5 th data frame may be used as a paging frame, and the 4 th subframe in the paging frame may be used as a paging time.
In practical application, the value range of the preset user group number is 0-1023, and/or the value range of the paging frame number is 0-1023.
In one mode, a bit indication of the paging frame number may be added to the SIBx signal, thereby expanding the range of the paging frame number. The system information block SIBx may be sent to the terminal device in the form of a system broadcast message through the access stratum.
The bit indication bits may be located at an upper or middle or lower position in the system information block.
Wherein, the bit indication bit can be preferably set to the high order of the system information block to be compatible with the existing terminal equipment. In this embodiment, the terminal device may read the high-order bit indication from the SIBx, and obtain the extended frame number corresponding to the current time by combining the low-order frame number in the system broadcast message, and the subsequent terminal performs the calculation of the extended frame number at each time according to the information.
In another mode, a bit indication of the paging frame number may also be added to an indication message sent by the network device to the terminal device, so as to expand the range of the paging frame number.
The bit indication bits may be located at a high or medium or low position in the indication message.
Wherein, the bit indication bit can be preferably set to the high order of the indication message to be compatible with the existing terminal equipment. In this embodiment, the terminal device may read the high-order bit indication from the indication message, and obtain the extended frame number corresponding to the current time by combining the low-order frame number in the system broadcast message, and the subsequent terminal performs the calculation of the extended frame number at each time according to the information.
In the above embodiment, if the bit indication is n bits, the paging frame number range is 0- (2) n * 1024-1). For example, adding 4 bits of high order bit indication, so that the full paging frame number range can be expanded to 0-16383. As another example, by adding 8 high order bits to indicate, the full paging frame number can be expanded to 262143.
