Description

Technical Field

[0001] This invention relates to the field of wireless communication technology, and in particular to a method, apparatus, and readable storage medium for determining a paging carrier and subcarrier group. Background Technology

[0002] In the coverage-level-based paging method, the base station configures a Reference Signal Receiving Power (RSRP) threshold value for each paging level, as well as a paging subcarrier group for each paging level, for the user equipment. The user equipment determines the corresponding coverage level based on the measured RSRP, and then randomly selects the appropriate paging carrier from the paging subcarrier group corresponding to the coverage level to receive paging messages.

[0003] The base station determines the coverage level of the user equipment application based on the RSRP or coverage level reported by the user. Based on the user equipment's identifier, the base station randomly selects the appropriate paging carrier from the paging subcarrier group corresponding to the coverage level to send paging messages.

[0004] However, if the coverage level of a user equipment (UE) changes, and the UE continues to use the previously determined coverage level for paging message reception, paging message reception may fail.

[0039] Compared with the prior art, the technical solution of the embodiments of the present invention has the following beneficial effects:

[0040] Based on the received configuration information and measured channel quality parameters, the user equipment determines the target paging subcarrier group for paging message reception.

[0041] Furthermore, after determining the target coverage level based on the received configuration information, the user equipment feeds back the target coverage level to the access network equipment, enabling the access network equipment to promptly know whether the coverage level corresponding to the user equipment has changed, and then adjust the target paging subcarrier group used for paging message transmission accordingly.

[0042] Furthermore, when a deterioration in channel quality is detected, the user equipment (UE) performs a corresponding backoff operation based on the currently used coverage level, thereby determining the target paging carrier for paging message reception after the backoff operation. This allows the UE to update the target paging carrier for user paging message reception in a timely manner, effectively preventing paging message reception failures.

[0043] If the user equipment is currently using the coverage level with the highest channel quality threshold, and the degree of channel quality change is unknown, it will directly fall back to the basic configuration mode. This can further prevent paging message reception failures. Attached Figure Description

[0052] As described in the background section above, when the coverage level of a user equipment (UE) changes, if the UE still uses the previously determined coverage level for paging message reception, paging message reception may fail. Simultaneously, the base station will also be unable to promptly detect changes in the UE's coverage level.

[0053] In this embodiment of the invention, the user equipment determines the target paging subcarrier group for paging message reception based on the received configuration information and the measured channel quality parameters. Therefore, the user equipment can update the target paging subcarrier group for user paging message reception in a timely manner, thereby effectively avoiding paging message reception failures.

[0054] To make the above-mentioned objectives, features and beneficial effects of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

The chip system may include a chip, and may also include other discrete components.

[0056] In this embodiment of the invention, the access network device is a device that provides wireless communication functions for terminal devices, and can also be referred to as a radio access network (RAN) device or access network element. The access network device can support at least one wireless communication technology, such as LTE, NR, etc. For example, the access network device includes, but is not limited to: next-generation base stations (gNB), evolved node B (eNB), radio network controllers (RNC), node Bs (NBs), base station controllers (BSCs), basetransceiver stations (BTSs), home base stations (e.g., home evolved node B, or home node B (HNB)), baseband units (BBUs), transmitting and receiving points (TRPs), transmitting points (TPs), mobile switching centers, etc., in 5th-generation (5G) mobile communication systems.

In some embodiments, access network devices can also be apparatuses that provide wireless communication functions for terminal devices, such as chip systems. For example, a chip system may include chips, and may also include other discrete devices.

[0057] In some embodiments, the access network device can also communicate with Internet Protocol (IP) networks, such as the Internet, private IP networks, or other data networks.

[0058] This invention provides a method for determining paging subcarrier groups, referring to... Figure 1 The following will provide a detailed explanation through specific steps.

[0059] In this embodiment of the invention, the paging subcarrier group determination method provided in steps S101 to S102 below can be executed by the user equipment. Specifically, the paging subcarrier group determination method provided in steps S101 to S102 below can be executed by a chip with data processing capabilities (such as a baseband chip) in the user equipment, or by a chip module in the user equipment that includes a data processing chip.

[0060] Step S101: Receive configuration information.

[0061] In practice, access network equipment can pre-deploy configuration information to user equipment.

[0062] In this embodiment of the invention, the configuration information may include paging subcarrier groups corresponding to each coverage level, and channel quality thresholds corresponding to each coverage level. The channel quality thresholds may include a channel quality strength threshold, or a channel quality strength threshold and a channel quality variation threshold.

[0063] User equipment can receive configuration information from the base station. The base station can broadcast configuration information via broadcast messages.

[0064] In this embodiment of the invention, the access network device can be configured with three coverage levels. For example, the configured coverage levels include a first coverage level CEL0, a second coverage level CEL1, and a third coverage level CEL2. The first coverage level CEL0 corresponds to the best channel quality, the second coverage level CEL1 corresponds to the next best channel quality, and the third coverage level CEL0 corresponds to the worst channel quality.

[0065] It is understandable that the number of coverage levels configured for access network devices can also be other than the specified number. For example, an access network device can be configured with two coverage levels, namely the first coverage level CEL0 and the second coverage level CEL1. The access network device can be configured with the appropriate number of coverage levels according to the specific application scenario.

[0066] In practice, access network devices can broadcast configuration information via system messages, with the configuration information carried by the system messages. User equipment can receive the system messages broadcast by the access network devices and obtain the configuration information from them.

[0067] Step S102: Based on the measured channel quality parameters and the configuration information, determine the target paging subcarrier group for receiving paging messages.

[0068] In practice, when the user equipment is in an idle state, it can perform channel quality parameter measurement operations to obtain the current channel quality status with the access network equipment.

[0069] In this embodiment of the invention, the channel quality parameter may include a channel quality strength parameter. In other embodiments of the invention, the channel quality parameter may also include a channel quality variation parameter.

[0070] In practice, if the configuration information only includes the channel quality strength threshold, then when the user equipment is in an idle state, only the channel quality strength parameter measurement operation can be performed.

[0071] In one embodiment of the present invention, the channel quality strength parameter is characterized by RSRP, and the channel quality transformation parameter is characterized by the change in RSRP.

[0072] It should be noted that the change in RSRP can be used to characterize the degree of change in RSRP over a period of time. In other words, the change in RSRP can characterize whether RSRP gradually increases, gradually decreases, or fluctuates within a certain range over a period of time. The aforementioned period of time can be preset. For example, the change in RSRP can be used to characterize the degree of change in RSRP within 2 seconds.

[0073] The user equipment compares the measured channel quality parameters with the corresponding channel quality thresholds to determine the target coverage level corresponding to the channel quality parameters, and uses the paging subcarrier group corresponding to the target coverage level as the target paging subcarrier group.

[0074] For example, RSRP1 < RSRP0. Both RSRP1 and RSRP0 are channel quality strength thresholds. When RSRP (the measured RSRP) is greater than RSRP0, the corresponding coverage level is CEL0; when RSRP is less than RSRP1, the corresponding coverage level is CEL2; and when RSRP is between RSRP0 and RSRP1, the corresponding coverage level is CEL1. If the user equipment detects that the RSRP measured in the idle state is between RSRP0 and RSRP1, then the target coverage level is determined to be CEL1.

[0075] If the user equipment determines that the target coverage level is CEL0, then the paging subcarrier group corresponding to the coverage level CEL0 is the target paging subcarrier group.

[0076] In this embodiment of the invention, if the user equipment determines the target coverage level, it can report the target coverage level, such as reporting the identifier corresponding to the target coverage level, after switching from the idle state to the connected state. Upon receiving the target coverage level, the access network device can determine the corresponding target paging subcarrier group and then use the target paging subcarrier group to send paging messages.

[0077] In other words, access network equipment uses the target paging subcarrier to send paging messages, and user equipment uses the target paging subcarrier to receive paging messages.

[0078] If the user equipment (UE) has determined the target coverage level, it can also report the target paging subcarrier group, such as its identifier, after switching from idle to connected state. Upon receiving the target paging subcarrier group, the access network device can determine whether to use it when sending paging messages.

[0079] In practice, if the configuration information includes a channel quality strength threshold and a channel quality change threshold, then when the user equipment is in an idle state, the channel quality strength parameter measurement operation and the channel quality change parameter measurement are performed.

[0080] The user equipment compares the measured channel quality strength parameters with the channel quality strength threshold, and compares the measured channel quality change parameters with the channel quality change threshold.

[0081] If the channel quality variation parameter is less than the channel quality variation threshold, the target coverage level corresponding to the channel quality parameter is determined based on the channel quality strength parameter and the channel quality strength threshold corresponding to each coverage level; the paging subcarrier group corresponding to the target coverage level is then used as the target paging subcarrier group. If the channel quality variation parameter is greater than the channel quality variation threshold, the specific paging subcarrier group or the general paging subcarrier group is used as the target paging subcarrier group.

[0082] If the channel quality change parameter is less than the RSRP change threshold, the user equipment continues to determine the target coverage level according to the rules in the example above. If the channel quality change parameter is greater than the RSRP change threshold, the user equipment uses a specific paging subcarrier group to receive paging messages (that is, uses the specific paging subcarrier group as the target paging subcarrier group), or uses a general paging subcarrier group to receive paging messages (that is, uses the general paging subcarrier group as the target paging subcarrier group).

[0083] In this embodiment of the invention, if the user equipment determines that the target paging subcarrier group is a specific paging subcarrier group, then when the user equipment switches from the idle state to the connected state, it can report the identifier corresponding to the specific paging subcarrier group to the access network device.

[0084] Accordingly, if the user equipment determines that the target paging subcarrier group is the target paging subcarrier group, then when the user equipment switches from idle state to connected state, it can report the identifier corresponding to the target paging subcarrier group to the access network equipment.

[0085] In practice, after determining the target paging subcarrier group, the user equipment can select one paging carrier from the target paging subcarrier group to receive paging messages.

[0086] In this embodiment of the invention, the user equipment may randomly select a paging carrier from the target paging subcarrier group to receive paging messages based on its own terminal identifier.

[0087] As can be seen, the user equipment determines the target paging subcarrier group for paging message reception based on the received configuration information and the measured channel quality parameters. Therefore, the user equipment can update the target paging subcarrier group for user paging message reception in a timely manner, effectively avoiding paging message reception failures.

[0088] Furthermore, after determining the target coverage level based on the received configuration information, the user equipment feeds back the target coverage level to the access network equipment, enabling the access network equipment to promptly know whether the coverage level corresponding to the user equipment has changed, and then adjust the target paging subcarrier group used for paging message transmission accordingly.

[0089] Reference Figure 2 The present invention provides a flowchart of another paging subcarrier group determination method in an embodiment of the present invention, which will be described in detail below through specific steps.

[0090] In this embodiment of the invention, the paging subcarrier group determination method provided in steps S201 to S203 below can be executed by the access network device. Specifically, the paging subcarrier group determination method provided in steps S201 to S203 below can be executed by a chip with data processing capabilities in the access network device, or by a chip module in the access network device that includes a data processing chip.

[0091] Step S201: Broadcast configuration information.

[0092] In practice, access network devices can pre-generate configuration information and broadcast it as a system broadcast message. User equipment served by the access network devices can receive the broadcast configuration information.

[0093] In this embodiment of the invention, the configuration information may include paging subcarrier groups corresponding to each coverage level, and channel quality thresholds corresponding to each coverage level. The channel quality thresholds may include a channel quality strength threshold, or a channel quality strength threshold and a channel quality variation threshold.

[0094] Step S202: Receive information reported by the user equipment.

[0095] Step S203: Determine the target paging subcarrier group for sending paging messages based on the information reported by the user equipment.

[0096] In practice, when the user equipment is in an idle state, it can perform channel quality parameter measurement operations to obtain the current channel quality status with the access network equipment.

[0097] In this embodiment of the invention, the channel quality parameter may include a channel quality strength parameter. In other embodiments of the invention, the channel quality parameter may also include a channel quality variation parameter.

[0098] In practice, if the configuration information only includes the channel quality strength threshold, then when the user equipment is in an idle state, only the channel quality strength parameter measurement operation can be performed.

[0099] The user equipment compares the measured channel quality parameters with the corresponding channel quality thresholds to determine the target coverage level corresponding to the channel quality parameters, and uses the paging subcarrier group corresponding to the target coverage level as the target paging subcarrier group.

[0100] For example, RSRP1 < RSRP0. Both RSRP1 and RSRP0 are channel quality strength thresholds. When RSRP (the measured RSRP) is greater than RSRP0, the corresponding coverage level is CEL0; when RSRP is less than RSRP1, the corresponding coverage level is CEL2; and when RSRP is between RSRP0 and RSRP1, the corresponding coverage level is CEL1. If the user equipment detects that the RSRP measured in the idle state is between RSRP0 and RSRP1, then the target coverage level is determined to be CEL1.

[0101] If the user equipment determines that the target coverage level is CEL0, then the paging subcarrier group corresponding to coverage level CEL0 is the target paging subcarrier group. After receiving the target coverage level, the access network equipment can determine the corresponding target paging subcarrier group and then use the target paging subcarrier group to send paging messages.

[0102] If the user equipment (UE) has determined the target coverage level, it can also report the target paging subcarrier group, such as its identifier, after switching from idle to connected state. Upon receiving the target paging subcarrier group, the access network device can determine whether to use it when sending paging messages.

[0103] In practice, if the configuration information includes a channel quality strength threshold and a channel quality change threshold, then when the user equipment is in an idle state, the channel quality strength parameter measurement operation and the channel quality change parameter measurement are performed.

[0104] The user equipment compares the measured channel quality strength parameters with the channel quality strength threshold, and compares the measured channel quality change parameters with the channel quality change threshold.

[0105] If the channel quality variation parameter is less than the channel quality variation threshold, the target coverage level corresponding to the channel quality parameter is determined based on the channel quality strength parameter and the channel quality strength threshold corresponding to each coverage level; the paging subcarrier group corresponding to the target coverage level is then used as the target paging subcarrier group. If the channel quality variation parameter is greater than the channel quality variation threshold, the specific paging subcarrier group or the general paging subcarrier group is used as the target paging subcarrier group.

[0106] If the channel quality change parameter is less than the RSRP change threshold, the user equipment continues to determine the target coverage level according to the rules in the example above. If the channel quality change parameter is greater than the RSRP change threshold, the user equipment uses a specific paging subcarrier group to receive paging messages (that is, uses the specific paging subcarrier group as the target paging subcarrier group), or uses a general paging subcarrier group to receive paging messages (that is, uses the general paging subcarrier group as the target paging subcarrier group).

[0107] In this embodiment of the invention, if the user equipment determines that the target paging subcarrier group is a specific paging subcarrier group, then when the user equipment switches from the idle state to the connected state, it can report the identifier corresponding to the specific paging subcarrier group to the access network device.

[0108] Accordingly, if the user equipment determines that the target paging subcarrier group is the target paging subcarrier group, then when the user equipment switches from idle state to connected state, it can report the identifier corresponding to the target paging subcarrier group to the access network equipment.

[0109] In practice, after determining the target paging subcarrier group, the user equipment can select one paging carrier from the target paging subcarrier group to receive paging messages.

[0110] In this embodiment of the invention, the access network device may randomly select a paging carrier from the target paging subcarrier group to send a paging message based on the terminal identifier of the user equipment.

[0111] Even if the access network device sends configuration information to the user equipment in advance, and the user equipment already knows the configuration information, the access network device can then determine the target paging subcarrier group. In other words, the user equipment can determine the target paging subcarrier group without relying on the configuration information.

[0112] After determining the target coverage level based on the measured channel quality parameters, the access network equipment can send the identification information corresponding to the target coverage level to the user equipment.

[0113] In practical implementation, the paging subcarrier group determination method provided in steps S101 to S102 is essentially the same as the paging subcarrier group determination method provided in steps S201 to S203. In the paging subcarrier group determination method provided in the above embodiments, the access network device first sends out configuration information, and the user equipment determines the target paging subcarrier group based on the received configuration information and the measured channel quality parameters.

[0114] However, the access network equipment may not send configuration information, or the configuration information sent by the access network equipment may only include the paging subcarrier groups corresponding to each coverage level. The user equipment cannot determine the target paging subcarrier group based on the received configuration information and the measured channel quality parameters.

[0115] The following explanation addresses the scenario where the user equipment cannot determine the target paging subcarrier group.

[0116] When a user equipment (UE) is in an idle state, it can perform channel quality parameter measurements to determine the current channel quality status with the access network equipment. Channel quality parameters may include channel quality strength parameters and channel quality variation parameters.

[0117] If the channel quality strength parameter is characterized by RSRP and the channel quality transformation parameter is characterized by the change in RSRP, then the user equipment can measure RSRP when it is in an idle state. Alternatively, both RSRP and the change in RSRP can be measured when the user equipment is in an idle state.

[0118] When a user equipment switches from idle to connected mode, it can report the measured channel quality parameters to the access network equipment.

[0119] If the channel quality parameters measured by the user equipment in the idle state only include RSRP, then after the user equipment switches from the idle state to the connected state, it can report the measured RSRP to the access network equipment. If the channel quality parameters measured by the user equipment in the idle state include both RSRP and RSRP change, then after the user equipment switches from the idle state to the connected state, it can report both the measured RSRP and RSRP change to the access network equipment.

[0120] After receiving the channel quality parameters reported by the user equipment, the access network equipment can determine the target paging subcarrier group based on the aforementioned channel quality parameters.

[0121] After determining the target paging subcarrier group, the access network equipment can generate first indication information and send it to the user equipment, indicating the target paging subcarrier group through the first indication information. For example, the first indication information carries relevant information corresponding to the target paging subcarrier group. The relevant information corresponding to the target paging subcarrier group may include: the identifier of each paging subcarrier in the target paging subcarrier group, the time and frequency resources corresponding to each paging subcarrier, etc.

[0122] After receiving the first indication information, the user equipment obtains the indicated target paging subcarrier group according to the first indication information. After re-entering the idle state, the user equipment can use the target paging subcarrier group to receive paging messages.

[0123] If the user equipment only reports RSRP, the access network equipment can determine the target coverage level corresponding to the user equipment based on the RSRP reported by the user equipment. If the user equipment reports both RSRP and RSRP changes, the access network equipment can determine the target coverage level corresponding to the user equipment based on both the RSRP reported by the user equipment and the RSRP changes.

[0124] Since different coverage levels correspond to different RSRPs, the access network device can determine the coverage level corresponding to the reported RSRP after receiving the RSRP reported by the user equipment.

[0125] For example, if RSRP1 < RSRP0, when the RSRP reported by the user equipment is greater than RSRP0, the corresponding coverage level is CEL0; when the RSRP reported by the user equipment is less than RSRP1, the corresponding coverage level is CEL2; when the RSRP reported by the user equipment is between RSRP0 and RSRP1, the corresponding coverage level is CEL1.

[0126] If the access network device detects that the RSRP reported by the user is greater than RSRP0, it determines that the target coverage level corresponding to the user equipment is CEL0.

[0127] After determining that the target coverage level corresponding to the user equipment is CEL0, the access network device learns that the target paging subcarrier group corresponding to the target coverage level CEL0 is paging subcarrier group 0. The access network device generates first indication information and sends it to the user equipment.

[0128] After receiving the RSRP and its change reported by the user equipment, the access network device determines that the RSRP change exceeds a predetermined range, i.e., the RSRP change is large. At this point, the access network device can determine whether the user equipment is using a specific paging subcarrier group or a general paging subcarrier group.

[0129] If the access network device determines to use a specific paging subcarrier group, the access network device can indicate the specific paging subcarrier group to the user equipment through the first indication information. At this time, the specific paging subcarrier group is the target paging subcarrier group.

[0130] Accordingly, if the access network device determines to use the general paging subcarrier group, it can indicate the general paging subcarrier group to the user equipment through the first indication information. In this case, the general paging subcarrier group is the target paging subcarrier group.

[0131] In practice, user equipment can also report the measured channel quality parameters to the access network equipment. Based on the received channel quality parameters, the access network equipment determines the target coverage level and sends a first indication message to the user equipment, which in turn indicates the identification information corresponding to the target coverage level.

[0132] According to the above embodiments, the access network device can determine the target subcarrier group corresponding to the user equipment based on the channel quality parameters reported by the user equipment. Therefore, the access network device can promptly detect changes in the channel quality corresponding to the user equipment and configure a target paging subcarrier group corresponding to the channel quality parameters for the user equipment, thereby effectively avoiding paging failures.

[0133] In the above embodiments of the present invention, the general paging subcarrier group or the specific paging subcarrier group can be a fixed paging subcarrier group pre-configured by the access network equipment, which may include one or more paging carriers, and the paging carriers included in the paging subcarrier group or the specific paging subcarrier group are different from the paging carriers included in the paging subcarrier group corresponding to the coverage level.

[0134] This invention also provides another method for determining paging carrier groups, referring to... Figure 3 The following will provide a detailed explanation through specific steps.

[0135] In this embodiment of the invention, the paging carrier group determination method provided in steps S301 to S302 below can be executed by the user equipment. Specifically, the paging carrier group determination method provided in steps S301 to S302 below can be executed by a chip with data processing capabilities (such as a baseband chip) in the user equipment, or by a chip module in the user equipment that includes a data processing chip.

[0136] Step S301: When a deterioration in channel quality is detected, perform the corresponding fallback operation according to the currently used coverage level.

[0137] In practice, when a user equipment (UE) detects a deterioration in channel quality, it means that the coverage level currently used by the UE may have changed. Therefore, when a UE detects a deterioration in channel quality corresponding to its current coverage level, it can perform a backoff operation corresponding to the current coverage level.

[0138] In this embodiment of the invention, the user equipment is configured to use at least two coverage levels, and the RSRP threshold values ​​corresponding to the at least two coverage levels are not equal.

[0139] If the coverage level currently used by the user equipment is not the coverage level with the worst channel quality, and if the channel quality corresponding to the currently used coverage level is detected to have deteriorated, and the user equipment cannot know the extent of the channel quality deterioration, then the user equipment can directly fall back to the basic configuration (legacy) mode.

[0140] In this embodiment of the invention, the legacy mode can be: the user equipment randomly selects a paging carrier for receiving paging messages from a pre-configured set of paging subcarriers based on the terminal identifier.

[0141] In this embodiment of the invention, when the channel quality corresponding to the coverage level currently used by the user equipment is optimal, if it is detected that the channel quality corresponding to the currently used coverage level has deteriorated, and the user equipment cannot know the extent of the channel quality deterioration, the user equipment can directly fall back to legacy mode.

[0142] For example, user equipment can be configured to use three coverage levels, namely coverage level CEL0, coverage level CEL1, and coverage level CEL2. Among them, the channel quality corresponding to coverage level CEL0 is the highest, the channel quality corresponding to coverage level CEL2 is the worst, and the channel quality corresponding to coverage level CEL1 is higher than that corresponding to coverage level CEL2 but lower than that corresponding to coverage level CEL0.

[0143] The user equipment is currently using coverage level CEL0. The user equipment detects a deterioration in the current channel quality, but does not know the extent of the deterioration. In this case, the user equipment directly falls back to legacy mode.

[0144] If the coverage level currently used by the user equipment is not the coverage level with the worst channel quality, and if a deterioration in the channel quality corresponding to the currently used coverage level is detected, and the user equipment cannot know the extent of the channel quality deterioration, then the user equipment can fall back to a coverage level with a channel quality worse than the currently used coverage level.

[0145] Continuing with the example above, the user equipment is currently using coverage level CEL0. If the user equipment detects a deterioration in the current channel quality, it will fall back to coverage level CEL1 or CEL2.

[0146] Alternatively, if the user equipment is currently using coverage level CEL1 and detects a deterioration in the current channel quality, it will fall back to coverage level CEL2.

[0147] When the coverage level currently used by the user equipment is not the coverage level with the worst channel quality, if the channel quality corresponding to the currently used coverage level is detected to deteriorate, and the user equipment knows the extent of the channel quality deterioration, the user equipment can backtrack to a coverage level with a channel quality worse than the currently used coverage level based on the known channel quality.

[0148] Continuing with the example above, the user equipment is currently using coverage level CEL0. If the user equipment detects a deterioration in the current channel quality, and the current channel quality is higher than the minimum RSRP threshold corresponding to coverage level CEL1, then the user equipment will fall back to coverage level CEL1.

[0149] The user equipment is currently using coverage level CEL0. If the user equipment detects a deterioration in the current channel quality, and the current channel quality is higher than the minimum RSRP threshold corresponding to coverage level CEL2 but lower than the minimum RSRP threshold corresponding to coverage level CEL1, the user equipment will fall back to coverage level CEL0.

[0150] Step S302: Determine the target paging carrier for receiving paging messages after the rollback operation is performed.

[0151] In practice, once the user equipment performs a rollback operation, the target paging carrier for receiving paging messages can be determined based on the rollback result.

[0152] In this embodiment of the invention, if the user equipment falls back to legacy mode, the paging carrier corresponding to legacy mode can be used as the target paging carrier.

[0153] If the user equipment falls back to the paging subcarrier group corresponding to the candidate coverage level, a paging carrier can be randomly selected from the paging subcarrier group corresponding to the candidate coverage level as the target paging carrier based on the terminal identifier of the user equipment.

[0154] For example, if a user equipment (UE) is currently using coverage level CEL1 and detects a deterioration in the current channel quality, it will fall back to coverage level CEL2. The UE will then select a paging carrier from the paging subcarrier group corresponding to coverage level CEL2, based on its own terminal identifier, as the target paging carrier.

[0155] In practice, after determining the target paging carrier, the user equipment can also report indication information to the access network equipment to inform the access network equipment of the updated target paging carrier.

[0156] This invention also provides a paging carrier determination method, referring to... Figure 4 The following will provide a detailed explanation through specific steps.

[0157] In this embodiment of the invention, the paging carrier determination method provided in steps S401 to S402 below can be executed by an access network device. Specifically, the paging carrier determination method provided in steps S401 to S402 below can be executed by a chip with data processing capabilities in the access network device, or by a chip module in the access network device that includes a data processing chip.

[0158] In this embodiment of the invention, the paging carrier determination method provided in steps S401 to S402 below can substantially correspond to the paging carrier determination method provided in steps S301 to S302 above. The difference is that the paging carrier determination method provided in steps S301 to S302 above is executed by the user equipment side, while the paging carrier determination method provided in steps S401 to S402 below is executed by the access network equipment side.

[0159] Step S401: When a paging failure is detected in the paging message, the corresponding rollback operation is performed according to the currently used coverage level.

[0160] In practice, when the access network device detects an error in the paging message, such as a paging message failure, it can be determined that the channel quality between the device and the user equipment has deteriorated, and the coverage level currently used by the user equipment may change.

[0161] Therefore, when the access network device detects that the channel quality corresponding to the currently used coverage level has deteriorated, it can perform a backoff operation corresponding to the currently used coverage level.

[0162] In practice, if the coverage level currently used by the access network device is not the coverage level with the worst channel quality, and an error is detected in the paging message sent, the access network device can directly fall back to legacy mode.

[0163] For example, the access network device is currently using the coverage level with the highest channel quality threshold. If an error is detected in the paging message, the access network device can directly fall back to legacy mode.

[0164] In practice, if there are candidate coverage levels, the access network device can fall back to the candidate coverage level. The channel quality threshold corresponding to the candidate coverage level is less than the channel quality threshold corresponding to the currently used coverage level.

[0165] Step S402: Determine the target paging carrier for paging message transmission after the rollback operation is performed.

[0166] In practice, after performing the corresponding rollback operation, the access network equipment can determine the target paging carrier for sending paging messages based on the result of the rollback operation.

[0167] For example, if the access network device falls back to legacy mode, the paging carrier corresponding to legacy mode will be used as the target paging carrier.

[0168] After determining the target paging carrier, the access network equipment can also indicate the target paging carrier to the user equipment through the first indication information.

[0169] In summary, when a deterioration in channel quality is detected, the user equipment (UE) performs a corresponding backoff operation based on the currently used coverage level, thereby determining the target paging carrier for paging message reception after the backoff operation. This allows the UE to update the target paging carrier for user paging message reception in a timely manner, effectively preventing paging message reception failures.

[0170] If the user equipment is currently using the coverage level with the highest channel quality threshold, and the degree of channel quality change is unknown, it will directly fall back to legacy mode. This can further prevent paging message reception failures.
