In order to make the present application better understood by those skilled in the art, the following description will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

Referring to fig. 2, fig. 2 is a flowchart of a paging carrier determining method according to an embodiment of the present application, which is applied to the communication system shown in fig. 1. As shown in fig. 2, the method comprises the steps of:

S210, the network device broadcasts first information to the terminal device, where the first information includes configuration information of a plurality of carriers.

In the embodiment of the application, when the network equipment needs to send downlink data to the terminal equipment in the RRC_IDLE state or inform the terminal equipment of updating the system information, the network equipment needs to configure configuration information of a plurality of carriers available for the terminal equipment to select so as to determine paging carriers to page the terminal equipment.

Optionally, the configuration information of the plurality of carriers includes at least one of: configuration information of at least one coverage level corresponding to each carrier, configuration information of at least one Discontinuous Reception (DRX) corresponding to each carrier, and DRX threshold list information.

Specifically, the network device may configure a corresponding carrier or carrier list for one or more coverage levels, and configure DRX of one or more sizes for carriers in the same coverage level list, respectively. For example, a carrier list of 3 DRX's is configured for CEL1 in the coverage level CEL list. Wherein DRX0 configures carrier_index 1,carrier_index2,carrier_index 3; DRX1 configures carrier_index 4,carrier_index 5,carrier_index 6; DRX2 configuration carrier_index 7,carrier_index 8,carrier_index 9. In some examples, the network device configures corresponding carrier/carrier lists for one or more sizes of DRX, respectively, and configures one or more coverage levels for the same size of DRX carrier, respectively. For example, for a carrier list of 3 CELs configured for DRX1 in the DRX list, CEL0 configures carrier_index 1,carrier_index2,carrier_index 3,CEL1 configures carrier_index 4,carrier_index 5,carrier_index 6; CEL2 configures carrier_index 7,carrier_index 8,carrier_index 9.

In practical application, when downlink data needs to be sent to a terminal device in rrc_idle state or the terminal device needs to be notified to update a system message, an MME in a core network may send a first Paging message to all network devices in all TAs registered by the terminal device. In order to enable the network device and the terminal device to select Paging carriers in a consistent manner, the core network may carry at least one of the identity of the paged terminal device and the coverage level, DRX class, DRX value of the paged terminal device to the network device via the first Paging message.

The traffic type information may include long period traffic indication information, medium period traffic indication information, or short period traffic indication information, and the delay type information may include delay sensitive indication information, delay insensitive indication information, or delay tolerant indication information. The network device may assist in selecting the paging carrier according to the information about the DRX value of the terminal device.

When the second information includes a coverage level of the terminal device, the network device may determine, according to the first information, a paging carrier from carriers corresponding to the coverage level of the terminal device; when the second information includes the DRX value and/or the DRX category of the terminal equipment, the network equipment can determine a paging carrier from carriers corresponding to DRX of the terminal equipment according to the first information; and when the second information comprises the coverage level of the terminal equipment, the DRX value of the terminal equipment and the DRX category of the terminal equipment, the network equipment determines a paging carrier from the coverage level of the terminal equipment and the carrier corresponding to the DRX according to the first information.

By way of example, suppose a network device configures a carrier list of 3 DRX's for CEL 1 in the CEL list, DRX0 configures carrier_index 1,carrier_index 2,carrier_index 3,DRX1 configures carrier carrier_index 4,carrier_index 5,carrier_index 6; DRX2 configures carrier_index 7,carrier_index 8,carrier_index 9, if the second information includes that the coverage level of the terminal equipment is CEL 1, determining a paging carrier from carriers carrier_index 1,carrier_index 2,carrier_index 3,carrier_index 4,carrier_index 5,carrier_index 6,carrier_index 7,carrier_index 8,carrier_index 9; if the second information includes that the coverage level of the terminal device is CEL 1 and the DRX of the terminal device is DRX1, determining a paging carrier from the carrier_index 4,carrier_index 5,carrier_index 6.

Specifically, when the second information includes the coverage grade of the terminal equipment, the network equipment determines a carrier set which can be used by the terminal equipment according to the coverage grade of the terminal equipment and carrier set information corresponding to the coverage grade; further, the paging carrier is further determined based on the set of available carriers. When the second information includes the DRX value or the DRX class of the terminal device, the network device may determine a carrier set that the terminal device may use according to the DRX class or the DRX value and the first information; the paging carrier is further determined based on the set of available carriers. The second information comprises a coverage level of the terminal equipment, and when the DRX value or the DRX class of the terminal equipment is included, the network equipment can determine a carrier set which can be used by the terminal equipment according to the coverage level, the DRX class or the DRX value and the first information; or determining a corresponding carrier set according to the coverage level of the terminal equipment, and then further determining the corresponding carrier set according to the DRX category or DRX numerical value of the terminal equipment; and further determines the paging carrier.

In one example, the determining the paging carrier based on the set of carriers includes:

comparing the DRX value corresponding to the carrier in the carrier set with the DRX value of the terminal equipment; and if the difference between the DRX value corresponding to the first carrier and the DRX value of the terminal equipment is minimum, determining the first carrier as the paging carrier, wherein the carrier set comprises the first carrier.

Specifically, the carriers in the carrier set are respectively configured with different DRX values, and when the second information includes the DRX value of the terminal device, the network device may compare the DRX value of the terminal device with the DRX value corresponding to the carrier in the carrier set, and use the carrier corresponding to the difference between the DRX value corresponding to the carrier in the carrier set and the DRX value of the terminal device as the paging carrier.

For example, the carrier set includes 3 carriers, the first carrier has a DRX value configured for 128 Radio Frames (RFs), the second carrier has a DRX value configured for 256 RFs, the third carrier has a DRX value configured for 512 RFs, the terminal device has a DRX value of 1024 RFs, and the third carrier in the carrier set is determined to be a paging carrier because the difference between the DRX value of the terminal device and the DRX value of the third carrier is the smallest.

In another example, the determining the paging carrier based on the set of carriers includes:

According to a first formula, a first numerical value is calculated, wherein the first formula is floor (UE _ID/(N*N_s)) modW, floor () represents a downward value, UE _ID is an identifier of the terminal equipment, N is a minimum value of DRX of the terminal equipment and the number of paging occasions in a DRX period, N _s is a maximum value of 1 and a second numerical value, the second numerical value is a ratio of the number of paging occasions in the DRX period to DRX of the terminal equipment, and M is a sum of corresponding weights of carriers in the carrier set; and if the first value is smaller than the sum of the corresponding weights or the normalized weights of K carriers in the carrier set, determining the K carrier as the paging carrier, wherein the carrier set comprises the K carriers, the K carrier corresponds to the K carrier or the R carrier in the plurality of carriers, and the K and the R are positive integers.

After determining the carrier set according to the coverage level of the terminal device and/or the DRX of the terminal device, the network device may select a corresponding paging carrier from the carrier set according to the first formula. The network device may randomly select a paging carrier among the set of carriers according to the existing configured carrier weights. The network device calculates the first value by the formula floor (UE _ID/(N*N_s)) modW. If the first value is smaller thanAnd l is the number of carriers in the carrier set, w (x) is the weight of the xth carrier in the carrier set, and the xth carrier corresponding to the weight w (x) is determined to be the paging carrier.

Specifically, according to the carrier sequence in the carrier set, comparing the weight value of the first carrier in the carrier set with a first value, and if the weight value is larger than the first value, determining the first carrier as a paging carrier; if the weight value of the first carrier is smaller than the first value, comparing the sum of the weight values of the first carrier and the second carrier in the carrier set with the first value, and if the sum is larger than the first value, determining the second carrier as a paging carrier; if the sum of the weight values of the first carrier and the second carrier is smaller than the first value, comparing the sum of the weight values of the first carrier, the second carrier and the third carrier in the carrier set with the first value, if the sum of the weight values of the first carrier, the second carrier and the third carrier is larger than the first value, determining the third carrier as a paging carrier, and then, analogizing until the last carrier in the paging carrier or the carrier set is determined.

In one example, the index of the carriers in the carrier set may be a continuous index value, and the xth carrier in the carrier set may correspond to the yth carrier of the plurality of carriers in the network device configuration first information, where the value of w (x) is equal to the value of w (y). For example, assuming that the carrier indexes of 4 carriers in the carrier set are 0,1,2 and 3, the 4 carriers configure the carriers x, y, j and q of the multiple carriers in the first information for the network device, a first value is calculated according to the first formula, and if the value of w (0) +w (1) +w (2) is greater than the first value, the carrier j of the multiple carriers in the first information corresponding to the carrier with the carrier index of 2 is determined as the paging carrier.

In another example, the index of the carriers in the carrier set may be a non-consecutive index value, and w (x) may configure the weight value of the xth carrier of the plurality of carriers in the first information for the network device. For example, carrier indexes of 4 carriers in the carrier set are 1,3, 5, 7, and 4 carriers are respectively carrier 1, carrier 3, carrier 5, and carrier 5 of multiple carriers in the first information configured by the network device, a first value is calculated according to a first formula, and if the value of w (1) +w (3) +w (5) is greater than the first value, the carrier with the carrier index of 5 is directly determined as the paging carrier.

In one embodiment, the weights of the carriers in the carrier set may be normalized, and then the paging carrier may be selected according to the first formula. For example, the carrier set is carrier_ indexi, carrier_index j, carrier_index k, the carrier weights are normalized, W (i) ' =w (i)/(W (i) +w (j) +w (k)), W (j) ' =w (i)/(W (i) +w (j) +w (k)), W (k) ' =w (i)/(W (i) +w (j) +w (k)), and then the normalized carrier weights are compared with the first value to determine the paging carrier.

The network device may directly use the existing weights of the carriers to determine the paging carrier, or may reconfigure the weights of the carriers to determine the paging carrier, which is not limited by the embodiment of the present application.

In one possible embodiment, the method further comprises: the network device sends a second paging message on the paging carrier.

After calculating the paging carrier of the terminal device, the network device may send a second paging message on the paging carrier to page the terminal device paged by the core network.

Specifically, for a terminal device supporting only coverage class grouping, a set of usable carriers may be determined according to its own coverage class; further, the paging carrier is further determined based on the set of available carriers. For a terminal device supporting only DRX packets, a set of carriers that can be used may be determined according to its DRX; further, a paging carrier is determined from the set of available carriers. For a terminal device supporting both coverage level grouping and DRX grouping, the terminal device can determine a set of usable carriers according to the coverage level, DRX category or DRX value and the first information; or determining a corresponding carrier set according to the coverage level of the carrier set, then further determining the corresponding carrier set according to the DRX class or the DRX numerical value of the carrier set, and further determining the paging carrier.
