All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 2, fig. 2 is a flowchart illustrating a method for determining a paging carrier 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 equipment broadcasts first information to the terminal equipment, wherein the first information comprises configuration information of a plurality of carriers.
In this embodiment of the present application, when the network device needs to send downlink data to the terminal device in the RRC _ IDLE state or notify the terminal device to update a system message, the network device needs to configure configuration information of multiple carriers that can be selected by the terminal device first, so as to determine a paging carrier to page the terminal device.
Optionally, the configuration information of the multiple 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 value list information.
Specifically, the network device may configure corresponding carriers or carrier lists for one or more coverage levels, and then configure DRX of one or more sizes for carriers in the same coverage level list, respectively. For example, a carrier list of 3 DRX is configured for CEL1 in the coverage level CEL list. Wherein the DRX0 configures carriers carrier _ index 1, carrier _ index2, carrier _ index 3; the DRX1 configures carriers carrier _ index 4, carrier _ index 5, carrier _ index 6; the DRX2 configures carriers carrier _ index 7, carrier _ index 8, and carrier _ index 9. In some examples, the network device configures corresponding carriers/carrier lists for one or more sizes of DRX carriers, and configures one or more coverage levels for the same size of DRX carriers. For example, for a carrier list in which 3 kinds of CELs are configured for DRX1 in the DRX list, CELs 0 configure carriers carrier _ index 1, carrier _ index2, carrier _ index 3, and CELs 1 configure carriers carrier _ index 4, carrier _ index 5, and carrier _ index 6; the CEL2 configures carriers carrier _ index 7, carrier _ index 8, carrier _ index 9.
Optionally, the DRX configuration information includes DRX value information and/or DRX category indication information, and the DRX threshold list information includes at least one threshold.
Wherein the DRX threshold list is composed of a plurality of DRX threshold values configured by the network device for all carriers. The DRX value information may be an index value of DRX, the DRX category indication information may be used to indicate a size of DRX, and DRX may include short DRX, medium DRX, long DRX, and the like.
In the embodiment of the application, the network may configure the relative DRX for the carriers of the same coverage level according to the characteristics of the coverage level, for example, for the carriers configured with extreme coverage, the problem of overlap may be solved by configuring the corresponding carriers with a larger DRX value, and for the carriers configured with normal coverage, the paging delay may be reduced by configuring the corresponding carriers with a smaller DRX value.
S220, the network equipment determines the paging carrier based on the first information.
In a possible embodiment, the method further comprises: receiving a first paging message, where the first paging message carries second information and/or an identifier of the terminal device, and the second information includes at least one of a coverage level of the terminal device, a DRX category of the terminal device, and a DRX value of the terminal device.
In practical application, when downlink data needs to be sent to the terminal device in the RRC _ IDLE state or the terminal device is notified to perform system message update, the MME in the core network may send the 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 the Paging carrier consistently, the core network may carry the identity of the paged terminal device and at least one of the coverage level, DRX class, DRX value of the paged terminal device to the network device via the first Paging message. And the network equipment can determine the paging carrier applying paging according to the carried information DRX type, DRX value and/or coverage level information.
In this embodiment of the present application, the first paging message may also carry information related to the DRX value of the terminal device, such as information of a service type and a delay sensitive type. The core network can acquire the service type information and the time delay type information of the terminal equipment from the subscription information of the terminal equipment. The service type information may include long period service indication information, medium period service indication information or short period service 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 can assist in selecting the paging carrier according to the information related to the DRX value of the terminal device.
The determining a paging carrier based on the first information comprises: determining the paging carrier based on the first information and the second information.
When the second information includes the 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 DRX category of the terminal device, the network device may determine, according to the first information, a paging carrier from carriers corresponding to DRX of the terminal device; and when the second information comprises the coverage level of the terminal equipment, the DRX value of the terminal equipment and the DRX type of the terminal equipment, the network equipment determines the paging carrier from the coverage level of the terminal equipment and the carrier corresponding to the DRX according to the first information.
For example, assuming that the network device configures a carrier list of 3 types of DRX for CEL1 in the CEL list, DRX0 configures carrier _ index 1, carrier _ index2, carrier _ index 3, DRX1 configures carrier _ index 4, carrier _ index 5, and carrier _ index 6; the DRX2 configures carriers carrier _ index 7, carrier _ index 8, and carrier _ index 9, and if the second information includes that the coverage class of the terminal device is CEL1, determines a paging carrier from carriers carrier _ index 1, carrier _ index2, carrier _ index 3, carrier _ index 4, carrier _ index 5, carrier _ index 6, carrier _ index 7, carrier _ index 8, and carrier _ index 9; if the second information includes that the coverage level of the terminal device is CEL1 and the DRX of the terminal device is DRX1, the paging carrier is determined from carriers carrier _ index 4, carrier _ index 5, and carrier _ index 6.
Optionally, the determining the paging carrier based on the first information and the second information includes:
determining a carrier set based on the coverage class of the terminal device and the first information in case that the terminal device supports coverage class grouping; determining a paging carrier set based on the DRX of the terminal equipment and the first information under the condition that the terminal equipment supports DRX grouping, wherein the DRX of the terminal equipment comprises a DRX category of the terminal equipment and/or a DRX value of the terminal equipment; determining the carrier set based on the coverage level of the terminal device, the DRX of the terminal device and the first information, in case the terminal device supports the coverage level packet and the DRX packet; determining the paging carrier based on the set of carriers.
Specifically, when the second information includes the coverage level of the terminal device, the network device determines, according to the coverage level of the terminal device and carrier set information corresponding to the coverage level, a carrier set that can be used by the terminal device; further, a paging carrier is further determined according to the usable carrier set. When the second information includes the DRX value or DRX category of the terminal device, the network device may determine, according to the DRX category or DRX value and the first information, a carrier set that can be used by the terminal device; a paging carrier is further determined based on the set of usable carriers. When the second information includes the coverage level of the terminal device, the DRX value or DRX category of the terminal device, the network device may determine, according to the coverage level, DRX category or DRX value, and the first information, a carrier set that can be used by the terminal device; or determining a corresponding carrier set according to the coverage level of the terminal equipment, and further determining the corresponding carrier set according to the DRX type or DRX 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 comprises:
comparing the DRX value corresponding to the carrier in the carrier set with the DRX value of the terminal equipment; and if the difference value 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, 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 minimum 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 DRX value of the first carrier is configured to be 128 Radio Frames (RF), the DRX value of the second carrier is configured to be 256 RF, the DRX value of the third carrier is configured to be 512 RF, the DRX value of the terminal device carried in the second information is 1024 RF, and the third carrier in the carrier set is determined to be the paging carrier because the difference between the DRX value of the terminal device and the DRX value of the third carrier is minimum.
In another example, the determining the paging carrier based on the set of carriers comprises:
calculating a first value according to a first formula, the first formula being floor (UE)ID/(N*Ns) Mod W, the floor () representing the value down, the UEIDThe identifier of the terminal equipment is obtained, the N is the minimum value of the DRX of the terminal equipment and the paging occasion number in the DRX period, and the N issThe value is the maximum value between 1 and a second value, the second value is the ratio of the number of paging occasions in the DRX period to the DRX of the terminal equipment, and M is the sum of weights corresponding to carriers in the carrier set; if the first value is smaller than the sum of the corresponding weights or normalized weights of the K carriers in the carrier set, determining the Kth carrier as the paging carrier, wherein the carrier set comprises the K carriers, the Kth carrier corresponds to the Kth carrier or the Rth carrier in the multiple carriers, and K and R are positive integers.
After determining a 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 a first formula. The network device may randomly select a paging carrier among the set of carriers based on the carrier weights of the existing configuration. Network equipment through formula floor (UE)ID/(N*Ns) Mod W calculates the first value. If the first value is less than
Figure BDA0002738179610000081
l is the number of carriers in the carrier set, w (x) is the weight of the xth carrier in the carrier setThen the x-th carrier corresponding to the weight w (x) is determined as 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 greater than the first value, determining the first carrier as a paging carrier; if the weight value of the first carrier is smaller than a first numerical value, comparing the sum of the weight values of the first carrier and the second carrier in the carrier set with the first numerical value, and if the sum is larger than the first numerical 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 a 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 and the second carrier is larger than the first value, determining the third carrier as a paging carrier, and repeating the steps until the paging carrier or the last carrier in the carrier set is determined.
In an example, the indexes of the carriers in the carrier set may be consecutive index values, the xth carrier in the carrier set may correspond to the yth carrier of the multiple carriers in the first information configured by the network device, and the value of w (x) is equal to the value of w (y). For example, suppose carrier indexes of 4 carriers in the carrier set are 0, 1, 2, and 3, the 4 carriers configure carrier x, carrier y, carrier j, and carrier q of multiple carriers in the first information for the network device, respectively, a first value is calculated through a first formula, and if a value of w (0) + w (1) + w (2) is greater than the first value, carrier j of multiple carriers in the first information corresponding to the carrier with carrier index2 is determined as a paging carrier.
In another example, the index of the carrier in the carrier set may be a non-consecutive index value, and w (x) may configure the network device with a weight value of an xth carrier of the plurality of carriers in the first information. For example, the carrier indexes of 4 carriers in the carrier set are 1, 3, 5, and 7, the 4 carriers configure the carrier 1, carrier 3, carrier 5, and carrier 5 of the multiple carriers in the first information for the network device, respectively, a first value is calculated through 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 includes carrier _ index i, carrier _ index j, and carrier _ index k, and the carrier weight is normalized, where w (i) ' (w (i))/(w (i)) + w (j)) + w (k)), w (j) ' ((w) (i)) + w (j)) + w (k)), and w (k) ', (w) (i))/(w (i)) + w (j)) + w (k)), and the normalized carrier weight is compared with the first value to identify the paging carrier.
In the description, the network device may determine the paging carrier by directly using the existing weight of the carrier, or may determine the paging carrier by reconfiguring the weight of the carrier, which is not limited in this embodiment of the present application.
In a possible embodiment, the method further comprises: the network device transmits a second paging message on the paging carrier.
After the network device calculates 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.
S230, the terminal device receives the first information sent by the network device and determines the paging carrier based on the first information.
