Description

TECHNICAL FIELD

[0001] The present application relates to the field of communication, and in particular to a communication method and apparatus. BACKGROUND

[0002] Currently, a terminal device in an idle state (RRC_IDLE) or an inactive state (RRC_INACTIVE) can receive a paging message by using a discontinuous reception (DRX) mechanism. Illustratively, the terminal device can only monitor a physical downlink control channel (PDCCH) in a specific subframe or time slot within a specific radio frame to obtain control information scrambled by a paging radio network temporary identifier (P-RNTI), and receive a paging message on a physical downlink shared channel (PDSCH) according to the control information. If the paging message includes the identifier of the terminal device, the terminal device enters a connected state; if the paging message does not include the identifier of the terminal device, the terminal device does not enter the connected state.

[0003] Further, the terminal device can also receive small data based on the above paging procedure. Specifically, after the terminal device monitors the control information scrambled by the P-RNTI, it receives a paging message on the PDSCH corresponding to the control information, and the paging message includes small data information and the identifier of the terminal device, which can avoid the terminal device receiving small data through a radio resource control (RRC) connection establishment / release complex procedure, thereby saving signaling overhead and reducing power consumption.

[0004] However, with the diversification of terminal devices, receiving small data based on the above paging procedure may not necessarily achieve the purpose of saving the power consumption of the terminal device. For example, the bit number of the paging message is greater than the maximum bit number of the paging message that the terminal device can receive, resulting in incorrect reception of the paging message. If the paging message includes service paging information of the terminal device, the terminal device will miss the paging and waste power consumption. For another example, a terminal device that does not receive small data through the paging procedure will monitor the control information scrambled by the P-RNTI, and will receive a paging message. If the paging message includes small data, it will cause the terminal device to incorrectly receive service paging information and / or small data in the paging message, or cause the terminal device to receive small data that is not needed, wasting the power consumption of the terminal device.

[0005] In addition, even if the terminal device can receive the small packet data through the paging procedure, the scheme can cause waste of power consumption of the terminal device. For example, after the terminal device receives the paging message including the small packet data and the identifier of the terminal device, the terminal device enters the connected state, and when it is found that there is no paging service to be processed, the connected state is released, thereby causing unnecessary power consumption. That is, the existing scheme of receiving the small packet data through the paging procedure has the problem of waste of power consumption of the terminal device. SUMMARY

[0006] Embodiments of the present application provide a communication method and device, which can avoid the terminal device from receiving unnecessary paging messages, thereby reducing the power consumption of the terminal device.

[0007] To achieve the above object, the present application adopts the following technical solutions:

[0008] In a first aspect, a communication method is provided, which includes: sending first indication information to a first network device, and receiving a first paging message from the first network device. The first indication information is used to indicate the capability of the communication device to receive the first paging message, and the first paging message includes service paging information and / or small packet data information, and the small packet data information includes small packet data or small packet data resource information.

[0009] Optionally, when the communication device is in the connected state, the first indication information is sent to the first network device. When the communication device is in the idle state or the inactive state, the first paging message is received from the first network device.

[0010] Based on the communication method in the first aspect and the following third aspect, after the first network device receives the first indication information sent by the communication device in the connected state, the first network device sends the first indication information to a second network device. The first indication information is used to indicate the capability of the communication device to receive the first paging message. When the communication device is in the idle state or the inactive state, after the first network device receives the first indication information from the second network device, the first paging message is sent to the communication device. The first paging message is determined according to the capability of the communication device to receive the first paging message, so as to improve the success rate of the communication device receiving the paging message, and can avoid receiving the small packet data which is not needed by the communication device, thereby reducing the power consumption of the communication device.

[0011] In a possible implementation manner of the first aspect, the first indication information includes second indication information and / or third indication information, the second indication information is used to indicate a maximum value of a size of the first paging message received by the communication device, and the third indication information is used to indicate whether the communication device receives small packet data through the first paging message. That is, the second indication information is used to indicate a maximum data amount, such as a maximum bit number, of the first paging message that can be received by the communication device, and the third indication information can be used to indicate that the communication device receives small packet data through the first paging message, or the third indication information can be used to indicate that the communication device does not receive small packet data through the first paging message.

[0012] Optionally, the third indication information used to indicate that the communication device does not receive small packet data through the first paging message can include that the third indication information can be used to indicate that the communication device does not support receiving small packet data through the first paging message, or the third indication information can be used to indicate that the communication device supports receiving small packet data through the first paging message, but does not receive small packet data through the first paging message based on a requirement of the communication device.

[0013] In a possible implementation manner of the first aspect, the communication method further includes: receiving the first paging message corresponding to the first resource, the first paging message corresponding to the first resource including small packet data information; or receiving the first paging message corresponding to the second resource, the first paging message corresponding to the second resource not including the small packet data information, the first resource being different from the second resource.

[0014] In this way, the communication device that does not support receiving small packet data through the first paging message can receive the first paging message corresponding to the second resource, that is, can receive the first paging message including only the service paging information, and can not receive the first paging message including only the small packet data information or including the small packet data information and the service paging information, thereby saving power consumption of the communication device.

[0015] In a possible implementation manner of the first aspect, the communication method further includes: receiving the first paging message corresponding to the third resource, the first paging message corresponding to the third resource including service paging information; or receiving the first paging message corresponding to the fourth resource, the first paging message corresponding to the fourth resource not including the service paging information, the third resource being different from the fourth resource.

[0016] Thus, the communication device supporting receiving the small packet data through the paging message, but not receiving the small packet data through the first paging message based on the requirement of the terminal device, can receive the first paging message corresponding to the third resource, that is, can receive the first paging message including only the service paging information or including the service paging information and the small packet data information, so as to avoid missing the paging, and can not receive the first paging message including only the small packet data information, so as to avoid receiving the unnecessary small packet data, thereby reducing the power consumption of the communication device.

[0017] With reference to the first aspect, in a possible implementation manner of the first aspect, the communication method further includes: receiving fourth indication information from the first network device. The fourth indication information is used to indicate whether the communication device receives the small packet data through the first paging message. That is, whether the communication device receives the small packet data through the first paging message can be determined by the communication device and the first network device in a negotiation manner.

[0018] The second aspect provides a communication method, which includes: receiving first indication information, and sending a first paging message. The first indication information is used to indicate the capability of the communication device receiving the first paging message.

[0019] With reference to the second aspect, in a possible implementation manner of the second aspect, the first indication information includes second indication information and / or third indication information. The second indication information is used to indicate the maximum value of the size of the first paging message received by the communication device. The third indication information is used to indicate whether the communication device receives the small packet data through the first paging message.

[0020] With reference to the second aspect, in a possible implementation manner of the second aspect, the first paging message is determined according to the first indication information. That is, the first network device can determine the content and / or size of the first paging message according to the capability of different communication devices receiving the first paging message, so as to reduce the power consumption of the communication device.

[0021] With reference to the second aspect, in a possible implementation manner of the second aspect, the first paging message is the first paging message corresponding to the first resource. The first paging message corresponding to the first resource includes the small packet data information. Alternatively, the first paging message is the first paging message corresponding to the second resource. The first paging message corresponding to the second resource does not include the small packet data information. That is, the first network device can implicitly indicate the content included in the first paging message through different resource configurations, so as to save the signaling overhead between the first network device and the communication device, thereby improving the resource utilization and the communication efficiency.

[0022] With reference to the second aspect, in a possible implementation of the second aspect, the first paging message is a first paging message corresponding to third resources, and the first paging message corresponding to the third resources includes service paging information; or the first paging message is a first paging message corresponding to fourth resources, and the first paging message corresponding to the fourth resources does not include service paging information. That is, the first network device can implicitly indicate the content included in the first paging message by different resource configurations, so as to save the signaling overhead between the first network device and the communication device, thereby improving the resource utilization and communication efficiency.

[0023] With reference to the second aspect, in a possible implementation of the second aspect, the communication method further includes: sending fourth indication information to the communication device.

[0025] In addition, the technical effects of the communication method of the second aspect can refer to the technical effects of the communication method of the first aspect, which will not be repeated here.

[0026] The third aspect provides a communication method, which includes: receiving first indication information, and sending the first indication information to a first network device. The first indication information is used to indicate the capability of a communication device to receive a first paging message. In this way, the second network device can store the first indication information locally after receiving the first indication information, and send the first indication information to the first network device when a paging message needs to be sent.

[0027] With reference to the third aspect, in a possible implementation of the third aspect, the first indication information includes second indication information and / or third indication information. The second indication information is used to indicate the maximum value of the size of the first paging message received by the communication device, and the third indication information is used to indicate whether the communication device receives small packet data through the first paging message.

[0028] In addition, the technical effects of the communication method of the third aspect can refer to the technical effects of the communication method of the first aspect, which will not be repeated here.

[0029] The fourth aspect provides a communication method, which includes: receiving fifth indication information from a first network device, and determining whether to receive a second paging message from the first network device according to the fifth indication information.

[0030] According to the communication method of the fourth aspect, the communication device determines whether to receive the paging message according to the fifth indication information indicating that the second paging message comprises the small packet data information and / or the service paging information. In this way, the communication device which does not support receiving the small packet data through the paging message can not receive the paging message comprising only the small packet data information, and can not receive the paging message comprising the small packet data information and the service paging information, thereby reducing the power consumption of the communication device. Accordingly, the communication device which supports receiving the small packet data through the paging message but does not receive the small packet data through the first paging message based on the requirement of the terminal device can receive the first paging message comprising only the service paging information or comprising the service paging information and the small packet data information, thereby avoiding missing the paging, and can not receive the first paging message comprising only the small packet data information, so as to avoid receiving the small packet data which is not needed, thereby reducing the power consumption of the communication device.

[0031] With reference to the fourth aspect, in a possible implementation manner of the fourth aspect, the communication method further comprises: receiving the first control information from the first network device.

Furthermore, transceiver 203 may include a receiver and a transmitter. Figure 2 (Not shown separately). The receiver is used to implement the receiving function, and the transmitter is used to implement the transmitting function. The transceiver 203 can be integrated with the processor 201 or exist independently, and is connected via the input / output port of the communication device 200 (…). Figure 2 (Not shown in the image) is coupled to processor 201, and this embodiment does not specifically limit this.

[0093] It should be noted that, Figure 2 The structure of the communication device 200 shown does not constitute a limitation on the communication device. Actual communication devices may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0094] The following will take communication equipment as an example as the terminal device, combined with... Figures 3-6 The communication method provided in the embodiments of this application will be described in detail.

[0095] Figure 3 This is a flowchart illustrating a communication method provided in an embodiment of this application. This communication method can be applied to… Figure 1 The communication shown is between the communication device and the first network device, and between the first network device and the second network device.

[0096] like Figure 3 As shown, the communication method includes the following steps:

[0097] S301, the terminal device sends a first instruction message to the first network device. Correspondingly, the first network device receives the first instruction message from the terminal device.

[0098] The first indication information is used to indicate the terminal device's ability to receive the first paging message.

[0099] It should be noted that the terminal device can send first indication information to the first network device while in a connected state. That is, once an RRC connection is established between the terminal device and the first network device, the terminal device can send first indication information to the first network device while in a connected state.

[0100] Optionally, the first indication information can comprise the second indication information and / or the third indication information. In this way, the terminal device can report the capability information of the terminal device to the first network device, so that the first network device configures the first paging message for the terminal device according to the capability information, thereby reducing the power consumption of the terminal device.

[0101] The second indication information can be used to indicate the maximum value of the size of the first paging message received by the terminal device.

[0102] It should be noted that the maximum value of the size of the first paging message can be the maximum number of bits of the first paging message. In this way, the terminal device can send the maximum number of bits of the first paging message that the terminal device can receive to the first network device, so that the first network device sends the first paging message to the terminal device according to the maximum number of bits, that is, the number of bits of the first paging message sent is less than or equal to the maximum number of bits, which can solve the problem that the terminal device cannot correctly receive the first paging message due to the number of bits of the first paging message being greater than the maximum number of bits of the paging message that the terminal device can receive, thereby missing the paging and wasting power consumption.

[0103] The third indication information can be used to indicate whether the terminal device receives small packet data through the first paging message. For example, the small packet data can be a small amount of data, such as not more than 1000 bits, and infrequent data packets generated in push, heartbeat packet, notification and other scenarios.

[0104] Optionally, the third indication information can be used to indicate that the terminal device receives small packet data through the first paging message, or the third indication information can be used to indicate that the terminal device does not receive small packet data through the first paging message.

[0105] Further, the third indication information used to indicate that the terminal device does not receive small packet data through the first paging message can comprise: the third indication information can be used to indicate that the terminal device does not support receiving small packet data through the first paging message, or the third indication information can be used to indicate that the terminal device does not want to receive small packet data through the first paging message at present.

[0106] That is, the terminal device that does not receive small packet data through the first paging message can be divided into two categories: the terminal device that does not support receiving small packet data through the first paging message, and the terminal device that supports receiving small packet data through the first paging message but does not receive small packet data through the first paging message based on the requirement of the terminal device. For example, when the terminal device has high power, it can not receive small packet data through the first paging message.

[0107] For the convenience of description, the terminal device which does not support receiving small packet data through the paging message is referred to as the first terminal device, and the terminal device which supports receiving small packet data through the paging message but does not receive small packet data based on the terminal device requirement is referred to as the second terminal device in the embodiments of the present application.

[0108] Optionally, the terminal device can periodically send the first indication information to the first network device. That is, the terminal device can regularly update its capability of receiving the first paging message, such as the second indication information and / or the third indication information.

[0109] S302, the first network device sends the first indication information to the second network device. Correspondingly, the second network device receives the first indication information.

[0110] In a possible design, the first network device can send the fourth indication information to the terminal device. Correspondingly, the terminal device receives the fourth indication information from the first network device.

[0111] Optionally, the fourth indication information can be used to indicate whether the terminal device receives small packet data through the first paging message, and the fourth indication information can be contained in the RRC connection release message.

[0112] That is, whether the terminal device receives small packet data through the first paging message can be determined by the terminal device and the first network device in a negotiated manner.

[0113] Exemplarily, the terminal device and the first network device determine whether the terminal device can receive small packet data through the first paging message in a negotiated manner, and the specific implementation manner can refer to the following steps one to three:

[0114] Step one, the terminal device sends the third indication information to the first network device. Correspondingly, the first network device receives the third indication information sent by the terminal device.

[0115] The specific implementation manner of the third indication information can refer to the above S301, and will not be described here.

[0116] Step two, the first network device sends the RRC connection release message to the terminal device. Correspondingly, the terminal device receives the RRC connection release message from the first network device.

[0117] Optionally, the RRC connection release message can include the fourth indication information. That is, the first network device can send the fourth indication information through the RRC connection release message to save the signaling overhead.

[0118] The fourth indication information can be used to indicate whether the terminal device receives the small packet data through the first paging message. Alternatively, the fourth indication information can be used to indicate the third indication information, whether the indication information of the terminal device local to the first network device is consistent with the indication information of whether the terminal device receives the small packet data through the first paging message. The value of the fourth indication information can be consistent or inconsistent.

[0119] Step three, the terminal device determines the third indication information according to the fourth indication information.

[0120] Suppose the fourth indication information indicates that the terminal device does not receive the small packet data through the first paging message, the terminal device can determine whether the local third indication information is consistent with the fourth indication information. If not, the third indication information is modified, such as the terminal device can directly replace the third indication information with the fourth indication information.

[0121] Suppose the fourth indication information is inconsistent, and the third indication information indicates that the terminal device receives the small packet data through the first paging message. The terminal device can modify the small packet data received through the first paging message to not receive the small packet data through the first paging message.

[0122] It should be noted that the specific operation of the terminal device after receiving the fourth indication information is not limited in the present application, and the terminal device and the network device can reach an agreement. The state of the terminal device in S302 is not limited, and the terminal device can be in idle state, connected state, or non-activated state.

[0123] The communication method among the terminal device, the first network device and the second network device when the terminal device is in idle state or non-activated state will be described in detail below in combination with S303-S304.

[0124] S303, the second network device sends the first indication information to the first network device. Correspondingly, the first network device receives the first indication information from the second network device.

[0125] That is, the second network device can send the stored first indication information to the first network device, so that the first network device sends the first paging message according to the first indication information.

[0126] In a possible design, the second network device sends a paging message to the first network device. Correspondingly, the first network device receives the paging message from the second network device.

[0127] Specifically, the paging message can include the first indication information. In this way, the second network device sends the first indication information to the first network device through the paging process, so as to save the signaling overhead between the first network device and the second network device.

[0128] Optionally, the paging message can further comprise service paging information and / or small packet data information.

[0129] The service paging information can comprise an identity of at least one terminal device, which can be used by the terminal device to determine whether to page itself, so as to determine whether to enter a connected state. If the identity of at least one terminal device comprises an identity of the terminal device, the terminal device can enter the connected state.

[0130] Exemplarily, the small packet data information can comprise small packet data and / or small packet data resource information. Optionally, the small packet data resource information can comprise scheduling information of the small packet data, which can be used to indicate the terminal device to receive the small packet data on corresponding resources, such as time-frequency resources of a PDSCH.

[0131] It should be noted that the second network device can send the first indication information to the first network device in the following cases.

[0132] For example, in the above S301, the first network device to which the terminal device is connected in the connected state is different from the first network device on which the terminal device camps in the idle state in S303, the second network device can send the first indication information to the first network device.

[0133] For another example, in the above S301, the first network device receives the first indication information sent by the terminal device in the connected state of the terminal device, and the first network device does not save the first indication information of the terminal device when there is no RRC connection between the terminal device and the first network device, i.e., the terminal device is in the idle state or the inactive state, and the second network device can send the first indication information to the first network device.

[0134] S304, the first network device sends a first paging message to the terminal device. Correspondingly, the terminal device receives the first paging message.

[0135] The first paging message comprises the small packet data information and / or the service paging information.

[0136] Optionally, the service paging information can comprise an identity of at least one terminal device. The specific role of the identity of at least one terminal device is described above in S303, which will not be described here.

[0137] In this way, after receiving the first paging message, the terminal device can match the identity of the terminal device with the identity of at least one terminal device in the first paging message, and if the identity of at least one terminal device comprises the identity of the terminal device, the terminal device can enter the connected state.

[0138] Exemplarily, the small packet data information can comprise small packet data and / or small packet data resource information. The specific implementation of the resource information about the small packet data can refer to S303, which will not be repeated here.

[0139] Optionally, the small packet data information can be contained in a non critical extension field of the first paging message.

[0140] Specifically, the small packet data information can be small packet data information for all terminal devices residing in the first network device; or the small packet data information can be small packet data information for part of the terminal devices residing in the first network device. For example, the small packet data information can comprise at least one first small packet data information, all terminal devices residing in the first network device can comprise at least one first terminal device group, the first terminal device group comprises at least one terminal device, and the first small packet data information corresponds to the first terminal device group one by one.

[0141] In a possible design, before sending the first paging message to the terminal device in S304, the first network device can determine the first paging message according to the first indication information.

[0142] That is, the first network device can determine the content of the first paging message according to the capability of the terminal device to receive the first paging message, so as to reduce the power consumption of the terminal device.

[0143] In some embodiments, the first network device can determine the first paging message according to the second indication information. The specific implementation of the second indication information can refer to S301, which will not be repeated here.

[0144] In this way, the first network device can determine the first paging message according to the maximum number of bits of the paging message that the terminal device can receive, so that the number of bits of the first paging message is less than or equal to the maximum number of bits, so as to improve the success rate of the terminal device receiving the first paging message, thereby reducing the power consumption of the terminal device.

[0145] In yet some embodiments, the first network device can determine the first paging message according to the third indication information. The specific implementation of the third indication information can refer to S301, which will not be repeated here.

[0146] Exemplarily, if the third indication information indicates that the terminal device does not receive the small packet data through the first paging message, the determined first paging message can only include the paging service information, and does not include the small packet data information, so that the terminal device which does not support receiving the small packet data through the first paging message can correctly receive the first paging message. Compared with the prior art in which the first paging message includes the paging service information and the small packet data, the terminal device cannot correctly receive the first paging message, and the power consumption of the terminal device can be saved.

[0147] Exemplarily, if the third indication information indicates that the terminal device can receive the small packet data through the first paging message, the first paging message can include the small packet data information, or the first paging message including the small packet data information and the paging service information can save the power consumption of the terminal device in receiving the small packet data through the complex process of RRC connection establishment / release.

[0148] In some other embodiments, the first network device can determine the first paging message according to the second indication information and the third indication information.

[0149] That is, when the first network device determines the first paging message, the two factors of the maximum number of bits of the first paging message and whether the terminal device receives the small packet data through the first paging message can be comprehensively considered. In this way, the determined first paging message can guarantee that the number of bits is less than or equal to the maximum number of bits, and the terminal device can correctly receive the first paging message, and the power consumption of the terminal device can be saved.

[0150] Optionally, the first network device can implicitly indicate the content included in the first paging message by the terminal device, such as sending the first paging message including different contents on different resources. In this way, the terminal device can receive the first paging message on a specific resource according to the third indication information, and the specific implementation manner is as follows.

[0151] In a possible design scheme, the first network device sends the first paging message on the first resource. Correspondingly, when the terminal device is the first terminal device, the first paging message corresponding to the first resource can not be received.

[0152] The first paging message corresponding to the first resource includes the small packet data information, such as the first paging message corresponding to the first resource only including the small packet data information, or including the small packet data information and the service paging information, and the first terminal device is a device which does not support receiving the small packet data through the paging message. For details, refer to the above S301, which will not be described here.

[0153] That is, the first network device can send the first paging message including only the small packet data information or including the small packet data information and the service paging information on the first resource, and the first terminal device not supporting receiving the small packet data through the paging message can not receive the first paging message including the small packet data information, so as to reduce the power consumption of the terminal device.

[0154] In another possible design, the first network device sends the first paging message on the second resource. Accordingly, when the terminal device is the first terminal device, the first paging message corresponding to the second resource is received.

[0155] The second resource is different from the first resource, and the first paging message corresponding to the second resource does not include the small packet data information, for example, the first paging message corresponding to the second resource includes only the service paging information.

[0156] That is, the first network device can send the first paging message including only the service paging information on the second resource, and the first terminal device can receive the first paging message on the second resource, so as to receive the first paging message including only the service paging information, thereby improving the success rate of receiving the paging message and reducing the power consumption of the terminal device.

[0157] It should be noted that when the terminal device is the terminal device receiving the small packet data information through the paging message, the terminal device can receive the first paging message corresponding to the first resource, or can receive the first paging message corresponding to the second resource.

[0158] In combination with Figure 4 , one DRX cycle of the terminal device can include 32, 64, 128, or 256 paging frames (PFs), and the paging frame can be a system frame, and one paging frame includes a starting point of one or more paging occasions (POs).

[0159] Specifically, the specific process of determining the first resource or the second resource can include determining a paging frame PF system frame number, and then determining a paging occasion PO.

[0160] Exemplarily, the specific implementation of determining the first resource can include steps four to five.

[0161] Step four, the paging frame PF system frame number is determined according to the following formula (1).

[0162] (SFN+PF_offset)mod T=(T div N)*(UE_ID mod N) (1)

[0163] Wherein, SFN is the system frame number of a paging frame PF to be monitored by the terminal device; PF_offset is an offset value corresponding to the paging frame PF, configured in a system message SIB1; the mathematical symbol mod represents a modulus; the mathematical symbol div represents an integer quotient obtained after two integers are divided; T is a DRX cycle of the terminal device, configured by the network; UE_ID is a 5th generation short temporary mobile subscription identifier (5G-S-TMSI) mod 1024, if the terminal device does not have a 5G-S-TMSI, a default identifier UE_ID=0 is used; and N is the total number of PFs in the DRX cycle T, configured in a system information block 1 (SIB1) of a system message.

[0164] Step five, the paging occasion PO is determined according to the following formula (2).

[0165] i_s=floor(UE_ID / N)mod Ns (2)

[0166] Wherein, i_s is the position of the paging occasion PO, the mathematical symbol floor is a floor function, UE_ID is a 5G-S-TMSI mod 1024, if the terminal device does not have a 5G-S-TMSI, a default identifier UE_ID=0 is used; the mathematical symbol mod represents a modulus; and Ns is the total number of POs in the PF, configured in a system message SIB1.

[0167] Exemplarily, the specific implementation manner of determining the second resource can include the following steps six to seven.

[0168] Step six, the paging frame PF system frame number is determined according to the above formula (1).

[0169] (SFN’+PF_offset’)mod T=(T div N)*(UE_ID mod N) (3)

[0170] Wherein, PF_offset' is an offset value corresponding to the paging frame PF, configured in a system message SIB1, PF_offset' is different from PF_offset in the above formula (1), SFN' obtained is different from SFN in the above formula (1), and thus the second resource is different from the first resource. The meanings of other symbols in formula (3) are the same as those in the above formula (1), which will not be described herein again.

[0171] Step seven, the paging occasion PO is determined according to the above formula (2).

[0172] Alternatively, the specific implementation of determining the second resource can include the following steps eight to nine.

[0173] Step eight, determining the paging frame PF system frame number according to the above formula (1).

[0174] Step nine, determining the paging occasion PO according to the following formula (4).

[0175] i_s = floor (UE_ID / N + n) mod Ns (4)

[0176] Wherein, n is an offset, an integer, and the meanings of other symbols in formula (4) are the same as those in formula (2) above, which will not be repeated here. The PO is offset, and thus the PO obtained is different from the first resource.

[0177] Alternatively, the specific implementation of determining the second resource can include the following steps ten to eleven.

[0178] Step ten, determining the paging frame PF system frame number according to the above formula (3), and obtaining a PF system frame number different from the first resource.

[0179] Step eleven, determining the paging occasion PO according to the above formula (4), and obtaining a PO different from the first resource.

[0180] It should be noted that the specific implementation of determining the first resource and the second resource is not limited by the present application. The implementation of determining the first resource can refer to the above steps six to seven, or steps eight to nine, or steps ten to eleven. Similarly, the implementation of determining the first resource can refer to the above steps four to five, as long as the first resource is different from the second resource.

[0181] Optionally, before sending the first paging message, the first network device can send the following configuration information to the terminal device: the first paging message corresponding to the first resource includes small packet data information, and / or the first paging message corresponding to the second resource does not include small packet data information. In this way, the terminal device can determine to receive the first paging message on the first resource or the second resource according to the third indication information and the above configuration information, so as to save the power consumption of the terminal device.

[0182] In a possible design, the first network device sends the first paging message on the third resource. Correspondingly, when the terminal device is the second terminal device, the first paging message corresponding to the third resource is received.

[0183] The first paging message corresponding to the third resource includes service paging information, such as the first paging message corresponding to the third resource including only service paging information or including small packet data information and service paging information. The second terminal device is a terminal device that supports receiving small packet data through a paging message but does not receive small packet data through the first paging message based on terminal device requirements. For details, refer to the foregoing S301, which will not be described here.

[0184] That is, the first network device can send the first paging message including only service paging information or including small packet data information and service paging information on the third resource. The second terminal device that supports receiving small packet data through a paging message but does not receive small packet data through the first paging message based on terminal device requirements can receive the first paging message including only service paging information or the first paging message including small packet data information and service paging information, so as to avoid missing paging.

[0185] In another possible design, the first network device sends the first paging message on a fourth resource. Accordingly, when the terminal device is the second terminal device, the terminal device does not receive the first paging message corresponding to the fourth resource.

[0186] The fourth resource is different from the third resource, and the first paging message corresponding to the fourth resource does not include service paging information, such as the first paging message corresponding to the fourth resource including only small packet data information.

[0187] That is, the first network device can send the first paging message including only small packet data information on the fourth resource, and the second terminal device can not receive the first paging message including only small packet data information, so as to avoid receiving unnecessary small packet data and save power consumption of the terminal device.

[0188] Optionally, the first network device can pre-configure the terminal device with the following information: the first paging message corresponding to the third resource includes service paging information, and / or the first paging message corresponding to the fourth resource does not include service paging information. In this way, the terminal device can determine which resource to receive the first paging message according to the third indication information, thereby saving power consumption of the terminal device.

[0189] It should be noted that when the terminal device is a terminal device that receives small packet data information, the terminal device can receive the first paging message corresponding to the third resource or the first paging message corresponding to the fourth resource.

[0190] Similar to the determination of the first resource or the second resource, the specific process of determining the third resource or the fourth resource can include: determining a paging frame PF system frame number, and determining a paging occasion PO. Specifically, the specific implementation manner of determining the third resource can refer to the specific implementation manner of determining the first resource in steps four to five, and the specific implementation manner of determining the fourth resource can refer to the specific implementation manner of determining the second resource in steps six to eleven. The present application does not limit the specific implementation manner of determining the third resource and the fourth resource, as long as the third resource is different from the fourth resource.

[0191] Based on Figure 3 According to the communication method shown in the figure, after the first network device receives the first indication information sent by the terminal device in the connected state, the first network device sends the first indication information to the second network device. The first indication information is used to indicate the capability of the terminal device receiving the first paging message. When the terminal device is in the idle state or the inactive state, after the first network device receives the first indication information from the second network device, the first network device sends the first paging message to the terminal device. The first paging message is determined according to the capability of the terminal device receiving the first paging message. The success rate of the terminal device receiving the paging message is improved, and the terminal device can avoid receiving small packet data that is not needed by the terminal device, thereby reducing the power consumption of the terminal device.

[0192] Figure 5 Another flowchart of the communication method provided by the embodiment of the present application is shown in the figure. The communication method can be applied to Figure 1 The communication between the communication device and the first access network device.

[0193] As Figure 5 The communication method includes the following steps:

[0194] S501, the first network device sends the fifth indication information. Correspondingly, the terminal device receives the fifth indication information from the first network device.

[0195] The fifth indication information is used to indicate that the second paging message includes small packet data information and / or service paging information. The small packet data information includes small packet data or small packet data resource information.

[0196] That is, the fifth indication information can indicate that the second paging message only includes small packet data information, only includes service paging information, or includes small packet data information and service paging information. In this way, the content included in the second paging message can be explicitly indicated, so that the terminal device determines whether to receive the second paging message. Compared with the prior art that the terminal device receives all paging messages, the communication method provided by the embodiment of the present application reduces the number of times that the terminal device receives the paging message, thereby saving the power consumption of the terminal device.

[0197] In a possible design, the first network device can send the first control information to the terminal device. Accordingly, the terminal device can receive the first control information.

[0198] The first control information can include fifth indication information, and the first control information is used to instruct the communication device to receive the second paging message. That is, the first network device can add the fifth indication information in the control information of the paging message.

[0199] Exemplarily, the first control information can be downlink control information (DCI) of the paging message, such as DCI format 1_0. The DCI format 1_0 scrambled by the P-RNTI can include: a short message indicator, a short message, frequency domain resource configuration information, time domain resource configuration information, transport block (TB) scaling, and the like. The specific content included in the DCI format 1_0 and the interpretation of each content are shown in Table 1.

[0200] Table 1

[0201]

[0202] The short message in Table 1 above occupies 8 bits, and indicates system information update and / or earthquake and tsunami warning system (ETWS) / commercial mobile alert service (CMAS). Specifically, the interpretation of each bit of the short message is shown in Table 2.

[0203] Table 2

[0204]

[0205] Optionally, the fifth indication information can use 6 reserved bits of the DCI format 1_0 in Table 1, or the reserved bits (i.e., the 3rd to 8th bits) of the short message in Table 2.

[0206] In combination with Table 1, exemplarily, the fifth indication information can occupy any 2 bits of the 6 reserved bits in Table 1 to indicate the content included in the paging message. For example, binary "01" indicates that only small packet data information is included; binary "10" indicates that only service paging information is included; binary "11" indicates that both the small packet data information and the service paging information are included; and binary "00" is reserved. The specific interpretation of each value of the 2 bits is not limited in the present application, and the specific content included in the paging message can be indicated.

[0207] In combination with Table 1, exemplary, the fifth indication information can also occupy any 1 bit of the 6 reserved bits in Table 1 to indicate the content included in the paging message. When only 1 bit is occupied, the 1 bit can be interpreted differently according to the type of terminal device. The following is illustrated respectively.

[0208] Taking the terminal device as the first terminal device for example, binary "0" indicates that the paging message includes small packet data information, such as only including small packet data information, or including small packet data information and service paging information; binary "1" indicates that the paging message does not include small packet data information, such as only including service paging information. Wherein, the first terminal device is a terminal device that does not support receiving small packet data through the paging message, and specific description is referred to the above S301, which will not be repeated here.

[0209] Taking the terminal device as the second terminal device for example, binary "0" indicates that the paging message includes service paging information, such as only including service paging information, or including small packet data information and service paging information; binary "1" indicates that the paging message does not include service paging information, such as only including small packet data information. Wherein, the second terminal device is a terminal device that supports receiving small packet data through the paging message, but does not receive small packet data through the first paging message based on the requirement of the terminal device, and specific description is referred to the above S301, which will not be repeated here.

[0210] In combination with Table 2, exemplary, the fifth indication information can occupy any 2 bits of the 3-8 reserved bits in Table 2 to indicate the content included in the paging message. For example, occupying the 3-4 bits, binary "01" indicates that the paging message only includes small packet data information; binary "10" indicates that the paging message only includes service paging information; binary "11" indicates that the paging message includes both small packet data information and service paging information; and binary "00" is reserved. The specific interpretation of each value of the 2 bits is not limited by the present application, as long as it can indicate the specific content included in the paging message.

[0211] In combination with Table 2, exemplary, the fifth indication information can also occupy any 1 bit of the 3-8 reserved bits in Table 2 to indicate the content included in the paging message. When only 1 bit is occupied, binary "0" and binary "1" have different interpretations. The following is illustrated respectively.

[0212] Taking the terminal device as the first terminal device for example, such as occupying the 3 bits in Table 2, binary "0" indicates that the paging message includes small packet data information, such as only including small packet data information, or including small packet data information and service paging information; binary "1" indicates that the paging message does not include small packet data information, such as only including service paging information.

[0213] For example, the terminal device is the second terminal device, and the 8th bit in Table 2 is occupied. The binary "0" indicates that the paging message includes service paging information, such as only including service paging information or including small packet data information and service paging information. The binary "1" indicates that the paging message does not include service paging information, such as only including small packet data information.

[0214] It should be noted that the fifth indication information can occupy the bits defined but not used in Table 1 or Table 2. For example, for the bit shown in the 3rd row of Table 2, when the bit is not used as an ETWS and CMAS indication, the fifth indication information can occupy the bit.

[0215] S502, the terminal device determines whether to receive the second paging message according to the fifth indication information.

[0216] Specifically, if yes, the terminal device performs the following S503, the function of the terminal device side receives the second paging message, and if no, the terminal device can not receive the second paging message sent by the first network device in the following S503.

[0217] For example, the terminal device is the first terminal device, if the fifth indication information indicates that the second paging message only includes service paging information, the first terminal device can receive the second paging message. For another example, if the fifth indication information indicates that the second paging message only includes small packet data information or includes small packet data information and service paging information, the first terminal device can not receive the second paging message. Wherein, the first terminal device is a terminal device that does not support receiving small packet data through the paging message, and the specific description is referred to the above S301, which will not be repeated here.

[0218] For example, the terminal device is the second terminal device, if the fifth indication information indicates that the second paging message only includes service paging information or includes small packet data information and service paging information, the second terminal device can receive the second paging message. For another example, if the fifth indication information indicates that the second paging message only includes small packet data information, the second terminal device can not receive the second paging message. Wherein, the second terminal device is a terminal device that supports receiving small packet data through the paging message, but does not receive small packet data through the first paging message based on the terminal device requirement, and the specific description is referred to the above S301, which will not be repeated here.

[0219] S503, the first network device sends the second paging message. Correspondingly, the terminal device receives the second paging message.

[0220] Wherein, the second paging message can include small packet data information and / or service paging information. The specific implementation of the small packet data information and the service paging information can be referred to the above S304.

[0221] It should be noted that before the terminal device receives the fifth indication information from the first network device at S501, the terminal device can also send the first indication information to the first network device. That is, Figure 5 The communication method shown can also include S301-S303, and further, the second paging message can be determined according to the first indication information. For details, refer to S301-S303, which will not be described here.

[0222] Based on Figure 5 The communication method shown, the terminal device determines whether to receive the paging message according to the fifth indication information indicating that the second paging message includes small packet data information and / or service paging information. In this way, the terminal device that does not support receiving small packet data through the paging message can not receive the paging message including only small packet data information, and can not receive the paging message including small packet data information and service paging information, thereby reducing the power consumption of the terminal device. Correspondingly, the terminal device that supports receiving small packet data through the paging message but does not receive small packet data through the first paging message based on the terminal device requirement can receive the first paging message including only service paging information or including service paging information and small packet data information, avoid missing paging, and can not receive the first paging message including only small packet data information, to avoid receiving unnecessary small packet data, thereby reducing the power consumption of the terminal device.

[0223] Figure 6 Another flowchart of the communication method provided by the embodiments of the present application is shown. The communication method can be applied to Figure 1 The communication between the communication device and the first access network device.

[0224] As Figure 6 The communication method shown includes the following steps:

[0225] S601, the first access network device sends the sixth indication information. Correspondingly, the terminal device receives the sixth indication information from the first network device.

[0226] The sixth indication information is used to indicate the state of the terminal device after receiving the small packet data.

[0227] Exemplarily, the sixth indication information can indicate that the terminal device enters the connected state, the idle state, the inactive state, or indicates that the terminal device does not enter the connected state after receiving the small packet data.

[0228] If the sixth indication information indicates entering the connected state, the terminal device enters the connected state; if the sixth indication information indicates entering the idle state, the terminal device enters or remains in the idle state; if the sixth indication information indicates entering the inactive state, the terminal device enters or remains in the inactive state; if the sixth indication information indicates not entering the connected state, the terminal device remains in the current state.

[0229] Optionally, the sixth indication information can indicate the state of all terminal devices receiving the small packet data through the paging message.

[0230] Alternatively, the sixth indication information can indicate the state of part of the terminal devices receiving the small packet data through the paging message. If the small packet data information includes one or more first small packet data information, the first small packet data information corresponds to one terminal device group, and one terminal device group includes one or more terminal devices, the sixth indication information can be used to indicate the state of the terminal device group receiving the small packet data.

[0231] In a possible design, the first access network device sends the second control information. Correspondingly, the second control information is received from the first network device.

[0232] The second control information includes the sixth indication information, and the second control information is used to indicate the terminal device to receive the third paging message. That is, the first network device can add the sixth indication information in the control information.

[0233] Exemplarily, the first control information can be the downlink control information (DCI) of the paging message, such as DCI format 1_0. The specific implementation of the DCI format 1_0 can refer to the specific implementation of the DCI format 1_0 in S501.

[0234] Optionally, the sixth indication information can occupy the reserved bit 6 bit of the DCI format 1_0 in Table 1, or the reserved bit of the short message in Table 2, that is, the 3th to 8th bit.

[0235] In combination with Table 1, exemplarily, the sixth indication information can occupy any 1 bit of the 6 reserved bits in Table 1 to indicate the state of the terminal device receiving the small packet data. For example, binary “0” indicates that the terminal device does not enter the connected state and keeps the original state after receiving the small packet data; binary “1” indicates that the terminal device enters the connected state after receiving the small packet data.

[0236] In combination with Table 2, exemplarily, the sixth indication information can occupy any 1 bit of the 3th to 8th reserved bits in Table 2 to indicate the state of the terminal device receiving the small packet data. For example, occupying the 3th bit, binary “0” indicates that the terminal device enters the connected state after receiving the small packet data; binary “1” indicates that the terminal device enters the idle state after receiving the small packet data.

[0237] It should be noted that the sixth indication information can also occupy multiple bits, such as 4 bits. The first bit of the 4 bits is set to "1" to indicate entering the connected state, the second bit is set to "1" to indicate entering the idle state, the third bit is set to "1" to indicate entering the inactive state, and the fourth bit is set to "1" to indicate not entering the connected state and keeping the current state. The embodiment of the present application does not limit the specific implementation mode of the sixth indication information.

[0238] Optionally, the sixth indication information can reuse the bits defined but not used in Table 1 or Table 2, such as the bits shown in the third row of Table 2. When the bits are not used as ETWS and CMAS indication, the sixth indication information can occupy the bits.

[0239] S602, the first access network device sends a third paging message. Correspondingly, the terminal device receives the third paging message.

[0240] The third paging message includes service paging information and / or small packet data information.

[0241] Optionally, the service paging information can include the identifier of the terminal device, and the small packet data information can include small packet data or small packet data resource information. For the specific implementation mode of the small packet data and the small packet data resource information, refer to the above S304, which will not be repeated here.

[0242] In another possible design, the third paging message includes the sixth indication information. That is, the first network device can send the sixth indication information through the paging message.

[0243] Exemplarily, the third paging message includes service paging information, and / or small packet data information, and / or the sixth indication information.

[0244] If the small packet data information includes one or more first small packet data information, the first small packet data information corresponds to a terminal device group one by one, and a terminal device group includes one or more terminal devices, the sixth indication information can be used to indicate the state of the terminal device group after receiving the small packet data.

[0245] It should be noted that the embodiment of the present application does not limit the sequence between the above S602 and the above S603.

[0246] S603, the terminal device determines the state of the terminal device according to the sixth indication information.

[0247] Exemplarily, assuming that the third paging message includes service paging information, small packet data information, and the sixth indication information, and the sixth indication information indicates that the terminal device does not enter the connected state after receiving the small packet data, the terminal device in the idle state does not enter the connected state after receiving the third paging message, and keeps the idle state.

[0248] It should be noted that before the terminal device receives the sixth indication information from the first network device in S601, the terminal device can also send the first indication information to the first network device. That is, Figure 6 The communication method shown can also include S301-S303, and further, the third paging message can be determined according to the first indication information. For specific implementation, refer to S301-S303, which will not be repeated here.

[0249] Based on Figure 6 The communication method shown, the terminal device determines the state after receiving the paging message including the small packet data information according to the sixth indication information indicating the state of the terminal device after receiving the small packet data. In this way, after the terminal device in the idle state or the inactive state receives the paging message including the small packet data information, it will not mistakenly enter the connected state without the paging service of the terminal device, which can save the signaling overhead of connection establishment / release connection, thereby reducing the power consumption of the terminal device.

[0323] The embodiments of the present application further provide a communication apparatus, which can be a terminal device or a circuit. The communication apparatus can be used to perform the actions performed by the terminal device in the above-mentioned method embodiments.

[0324] When the communication apparatus is a terminal device, Figure 12 a simplified structure diagram of the terminal device is shown. For the convenience of understanding and illustration, Figure 12 In the figure, the terminal device takes a mobile phone as an example. As shown in the figure, Figure 12 the terminal device includes a processor, a memory, a radio frequency circuit, an antenna, and an input and output apparatus. The processor is mainly used for processing communication protocols and communication data, controlling the terminal device, executing software programs, processing data of the software programs, etc. The memory is mainly used for storing software programs and data. The radio frequency circuit is mainly used for conversion between baseband signals and radio frequency signals and processing of the radio frequency signals. The antenna is mainly used for receiving and transmitting radio frequency signals in the form of electromagnetic waves. The input and output apparatus, such as a touch screen, a display screen, a keyboard, etc., is mainly used for receiving data input by a user and outputting data to the user. It should be noted that some types of terminal devices can not have the input and output apparatus.

[0325] When data needs to be sent, the processor performs baseband processing on the data to be sent, and outputs the baseband signal to the radio frequency circuit. The radio frequency circuit performs radio frequency processing on the baseband signal, and transmits the radio frequency signal in the form of electromagnetic waves through the antenna. When data is sent to the terminal device, the radio frequency circuit receives the radio frequency signal through the antenna, converts the radio frequency signal into a baseband signal, and outputs the baseband signal to the processor. The processor converts the baseband signal into data and processes the data. For the convenience of illustration, Figure 12 ​​Only one memory and processor are shown in the illustration.
