Description

Paging method and device
Technical Field
The present invention relates to the field of mobile communications, and more particularly, to paging techniques in wireless communication systems.
Background
In the existing communication technology, a network device may send a paging message to terminal devices in an idle state and a connected state, and the paging process may be triggered by a core network to notify a certain terminal device to receive the paging message; or the paging process may be triggered by the base station to notify the system of message update and to notify the terminal device to receive some special information, such as information of earthquake, tsunami warning system or commercial mobile alert service. The state of the terminal device in INACTIVE state introduced in the 5G system, in the INACTIVE state, the paging procedure may be triggered by the base station, and when the base station receives signaling or user data from the core network, the paging procedure is triggered, and a paging message is sent to the terminal device so as to trigger the terminal device to access.
In order to avoid the degradation of the quality of wireless signals, the 5G communication system adopts beam forming technology, and a base station must use a plurality of beams with different directions to completely cover a cell. For paging, the base station needs to send a paging message once in each beam (i.e. all directions), as shown in fig. 1, the base station uses 8 beams to cover its serving cell, where 3 terminal devices need to be paged, i.e. terminal device 1, terminal device 2 and terminal device 3, and the paging messages of 3 terminal devices need to be sent once on all beams.
When a cell is covered by multiple beams, each cell needs to repeatedly transmit paging messages on multiple beams, which results in waste of resources. Therefore, the prior art proposes an optimization scheme, that is, a network device divides terminal devices into a plurality of groups, and then sends a round of paging indication on all beams, where the paging indication carries information about whether terminal devices belonging to at least one group are paged, and since the indication does not need to carry a complete terminal device identifier, the paging indication is small. After receiving the paging indication, the terminal device determines whether the group in which the terminal device is located is paged, if the terminal device is paged, the terminal device initiates a paging response to the network device through the beam corresponding to the group, and the network device sends a paging message to the terminal device through the beam corresponding to the paging response.
In the prior art, a paging message can only be sent on certain beams which receive a paging indication response message of a terminal device, the beams corresponding to the terminal device are changed due to the shielding of the terminal device, the shielding of the beams, or the movement of the terminal device, and the like, and the information that the beams corresponding to the terminal device are changed cannot be timely known by a network device, so that the beams corresponding to the sending of the paging message cannot be timely determined according to the information that the beams are changed.
Disclosure of Invention

Compared with the prior art, the scheme provided by the embodiment of the invention can enable the network equipment to determine the beam for sending the paging content according to the paging sending mode reference information.
For example, the paging transmission mode reference information includes at least one of: a speed attribute of the terminal device, a mobility attribute of the terminal device, a type of the terminal device, or an identity of at least one beam recommended by the terminal device.
In one possible design, the paging indication information includes paging information of at least one terminal device group, the paging information includes information on whether a first terminal device group is paged, and before the terminal device determines to respond to the paging indication according to the paging indication information, the method includes: and the terminal equipment determines that the terminal equipment belongs to the first terminal equipment group according to the reverse order of the terminal equipment identification bits or partial high-order bits of the terminal equipment identification, and determines whether to respond to the paging indication information according to the information whether the first terminal equipment group is paged, wherein the partial high-order bits are the first N bits of the terminal equipment identification from high to low, and N is a positive integer. The method adopts the reverse grouping mode of the terminal equipment identification bits or adopts part of high-order bits of the terminal equipment identification to carry out grouping by utilizing the high-order bits of the terminal equipment, so that the terminal equipment in one paging time machine can be grouped again, different terminal equipment in one paging time machine is dispersed into different groups, and the problem that how to carry out grouping on the terminal equipment in one paging time machine cannot be solved in the prior art is avoided, namely, after the terminal equipment is grouped according to the low-order bits in one paging time machine, all the terminal equipment in the group are still grouped into one group.
In another example, the terminal device determining to respond to the paging indication information according to the paging indication information includes: the paging indication information comprises part bits of the terminal equipment identification, and the terminal equipment determines to respond to the paging indication information according to the part bits of the terminal equipment identification included in the paging indication information. By adopting the scheme, the information quantity of the paging indication can be reduced, so that the load of the paging indication is reduced.
In one possible design, after the terminal device determines to respond to the paging indication information according to the paging indication information, before the terminal device sends first paging indication response information to a network device, the method includes: and the terminal equipment determines the paging sending mode reference information according to at least one of the attribute of the terminal equipment, the type of the terminal equipment and the beam quality measured by the terminal equipment. Wherein the attributes of the terminal device include: a speed attribute or a mobility attribute; the types of the terminal equipment comprise: vehicle-mounted equipment, intelligent terminal or machine terminal.

In one possible design, the paging transmission mode reference information includes at least one of: the speed attribute of the terminal device, the mobility attribute of the terminal device, the type of the terminal device, and the identifier of at least one beam recommended by the terminal device. Therefore, different terminal devices can send different paging sending mode reference information, so that the network determines a first beam according to the different paging sending mode reference information and transmits the first beam to the terminal device.

The time point of the first paging indication information is used as the time of the first paging indication response or the time of the transmission of the paging content, so that the time of the first paging indication response or the time of the transmission of the first paging content by all the terminal devices can adopt the same reference. The problem that the first paging indication response cannot be received due to the fact that time windows of the network equipment and the terminal equipment are inconsistent in the prior art is solved.
In another example, after the terminal device sends the first paging indication response information to the network device, the method further includes: and the terminal equipment determines the starting time and/or the ending time for receiving the paging content according to the time corresponding to the paging indication information. Wherein a start time of the paging content reception is N + S1, where N is a time corresponding to a paging indication, and S1 is a predefined value or a value received from the network device; or, the ending start time of the paging indicator transmission is N + E1, where N is a time corresponding to the paging indicator, the E1 is a predefined value or a value received from the network device, and when both E1 and S1 are involved, the E1 is greater than or equal to the S1. And the sending time and/or the ending time of the paging content are determined, so that the terminal equipment can determine the sending time window for receiving the paging response information, and the terminal equipment is prevented from monitoring the paging content additionally, so that the power consumption of the terminal equipment is reduced.
In one possible design, after the terminal device sends the first paging indication response message to the network device, the method further includes: and when the wave beam corresponding to the first paging indication response information changes, the terminal equipment sends second paging indication response information to the network equipment. The second paging indication response information can enable the network device to know that the beam of the terminal device changes, so that the paging content is retransmitted according to the changed beam.
In one possible design, the sending, by the terminal device, the second paging indication response information to the network device includes: and if the terminal equipment determines that the time window for sending the first paging indication response information does not expire, the terminal equipment sends the second paging indication response information to the network equipment.

Even if the terminal device sends the paging indicator to the network device, the network device will not receive or incorrectly consider the paging indicator response as a response to other paging indicator information.
In one possible design, the method further includes: if the terminal device does not receive the paging content, sending paging check request information to the network device, wherein the paging check request information carries an identifier of the terminal device, and the identifier of the terminal device is used for the network device to determine whether the paging content of the terminal device exists according to the paging check request information of the terminal device.

Further, the terminal device needs to determine whether it is in the paged group, and the determination method is that the terminal device may obtain the terminal device group in which the terminal device is located by using the following formula (1):
number (N) of terminal device groups mod in reverse order of terminal device identifiers (equation 1)
Assuming that the current identifier of the terminal device is 101011111 and the reverse order of the identifiers of the terminal device is 111110101, it is determined that the identifier of the terminal device belongs to the 1 st terminal device group according to the above formula (1) and table 1, and the first terminal device group in the paging indicator is not paged, so that the terminal device determines not to respond to the paging indicator information. Assuming that the paging indication is 1100010000, it means that the 1 st terminal device group, the 2 nd terminal device group and the 6 th terminal device group are paged, if the terminal device identity is still 101011111, the terminal device determines that the terminal device identity belongs to the 1 st terminal device group according to formula (1) and table 1, and the terminal device determines to respond to the paging indication information.
Illustratively, the paging indication information includes paging information of at least one terminal device group, the paging information includes information on whether a first terminal device group is paged, and the terminal device determines, according to the paging indication information, before responding to the paging indication, the method includes: and the terminal device determines that the terminal device belongs to the first terminal device group according to part of high-order bits of the terminal device identifier, and determines whether to respond to the paging indication information according to information whether the first terminal device group is paged, wherein the part of high-order bits of the terminal device identifier can be N bits from top to bottom in a bit sequence contained in the terminal device identifier, and N is a positive integer. For example, when the current paging indicator is 0100010000, the current identifier of the terminal device is 101011111, where the high order bits of the identifier portion of the terminal device are 1010, and it is determined that the identifier of the terminal device belongs to the 1 st terminal device group according to the following formula (2) and table 1:
number (N) of terminal device groups mod of some high order bits of terminal device identification (equation 2)
According to the paging indication, the 1 st terminal equipment group is not paged, so the terminal equipment determines not to respond to the paging indication information. It should be noted that the number N of terminal device groups may be predefined by the terminal device, or may be notified by the network device.
For another example, when the current paging indicator is 1100010000, the current identifier of the terminal device is 101011111, where the high order bit of the identifier portion of the terminal device is 1010, it is determined that the identifier of the terminal device belongs to the 1 st terminal device group according to the above formula (2) and table 1, and the 1 st terminal device group is paged according to the paging indicator, so that the terminal device determines to respond to the paging indicator information.
It should be particularly emphasized that the division range of some high-order bits may be configured by the network device or may be predefined by the terminal device.
By adopting the reverse order of the terminal equipment identification and the grouping mode of partial high-order bits of the terminal equipment, the terminal equipment in one paging time machine can be grouped again, so that different terminal equipment in one paging time machine can be dispersed into different groups, and the problem that in the prior art, after the terminal equipment is grouped according to the low-order bits in one paging time machine, all the terminal equipment in the group are still grouped into one group, namely, the grouping of the terminal equipment in one paging time machine can not be realized, and the paging of the terminal equipment can not be completed is avoided.
Illustratively, the paging indication information includes a part of bits of the terminal device identifier, and the terminal device determines to respond to the paging indication information according to the part of bits of the terminal device identifier included in the paging indication information. By adopting the scheme, the information quantity of the paging indication can be reduced, so that the load of the paging indication is reduced.
For example, the paging indication includes a part of bits of the terminal device identifier, for example, the part of bits may be first 3 bits of the terminal device identifier, that is, "111", the terminal device determines whether the first 3 bits of the terminal device identifier of the terminal device is "111", and if so, responds to the paging indication information. As another example, the terminal device is identified as 11110000110, if the paging indicator is a terminal with first three bits of "111", the terminal device determines that the paging indicator information needs to be responded, otherwise the terminal device does not respond to the paging indicator information.
204. The terminal device sends first paging indication response information to the network device, wherein the first paging indication response information carries paging sending mode reference information, and the paging mode reference information is used for the network device to determine a first beam for sending paging content.
Illustratively, the paging transmission mode reference information includes at least one of: a speed attribute of the terminal device, a mobility attribute of the terminal device, a type of the terminal device, or an identity of at least one beam recommended by the terminal device.
Illustratively, the sending, by the terminal device, the first paging indication response information to the network device includes: the terminal device determines the sending start time of the paging indication information and/or the sending end time of the paging indication information according to the time corresponding to the paging indication information, and the terminal device sends the first paging indication response information to the network device according to the sending start time and/or the sending end time.
The starting time of sending the paging indication response information is N + S, where N is the time corresponding to the paging indication information, and S is a predefined value or a value received from the network device, and may be, for example, a slot, a subframe, or a time unit; and/or the end time of sending the paging indication information is N + E, where N is the time corresponding to the paging indication information, and E is a predefined value or a value received from the network device, and is greater than or equal to S. For example, the time unit is a subframe, and if the terminal device receives the paging indication information in the nth subframe, the time for the terminal device to send the first paging indication response information is between the N + S subframe and the N + E subframe.
It should be noted that, the time window for the terminal to send the paging indication response message is between N + S and N + E, and if S ═ E, the time window for sending the paging indication response message is only one time unit, and the start time and the end time of the sent paging indication response message are overlapped.
205. The network equipment receives first paging indication response information sent by the terminal equipment, wherein the first paging indication response information carries paging sending mode reference information.
Illustratively, the paging transmission mode reference information includes at least one of a speed attribute of the terminal device, a mobility attribute of the terminal device, a type of the terminal device, and an identifier of at least one beam recommended by the terminal device.
Illustratively, the network device determines a reception start time of the paging indication information and/or a reception end time of the paging indication information according to a time corresponding to the paging indication information, and receives the first paging indication response information sent by the terminal device according to the reception start time and/or the reception end time. By specifying a first paging indication response transmission start time and/or a transmission end time, enabling the network device to determine a time window for receiving the first paging indication response information, the beam and time for transmitting the paging content may be determined from the first paging indication response information received within the time window.
Wherein, the starting time of the paging indication information reception is N + S, where N is the time corresponding to the paging indication information, and S is a predefined value; and/or the end time of the paging indication information reception is N + E, where N is the time corresponding to the paging indication information, E is a predefined value, and E is greater than or equal to S, where N, E, E1, S1, and S are positive integers. The time point of the first paging indication information is used as the time of the first paging indication response or the time of the transmission of the paging content, so that the time of the first paging indication response or the time of the transmission of the first paging content by all the terminal devices can adopt the same reference. The method and the device avoid the problem that the first paging indication response cannot be received due to the fact that time windows of the network equipment and the terminal equipment are inconsistent in the prior art.
For example, please refer to the description in step 204 for the content of the paging mode reference information, which is not described herein again.
206. And the network equipment determines a first wave beam according to the paging mode reference information and sends paging content to the terminal equipment through the first wave beam.
As described above, the paging mode reference information may include at least one of: a speed attribute of the terminal device, a mobility attribute of the terminal device, a type of the terminal device, or an identity of at least one beam recommended by the terminal device.
For example, the speed attribute of the terminal device may include a low speed attribute, a medium speed attribute, or a high speed attribute. The network device may determine, according to the difference in the speed attributes, a first beam corresponding to when the paging content is transmitted. If the terminal device reports the low-speed attribute, the first beam may only include the beam corresponding to the first paging indication response information; if the terminal device reports the high speed attribute, the first beam may include a beam corresponding to the first paging indication response information and other beams in the cell, where the other beams may be all beams except the first beam in the cell, or may be adjacent beams to the beam corresponding to the first paging indication response information.
As another example, the mobility attributes of the terminal device may include a terminal device that is not moving or a terminal device that is moving. The network device may determine a first beam to transmit paging content based on a difference in mobility attributes. If the mobility attribute reported by the terminal device is a non-moving terminal device, the first beam may only include a beam corresponding to the first paging indication response information. If the mobility attribute reported by the terminal is the mobile terminal device, the first beam may include a beam corresponding to the first paging indication response information and other beams in the cell, where the other beams may be all beams of the network device in the cell except the first beam, or beams adjacent to the beam corresponding to the first paging indication response information.
Also for example, the terminal device type may include a vehicle terminal device, an intelligent terminal device, or a machine terminal device. The network device may determine a range of a first beam transmitting paging content based on device type. If the terminal device type reported by the terminal device is a machine terminal device, the first beam may only include a beam corresponding to the first paging indication response information. If the terminal device type reported by the terminal device is an intelligent terminal device, the first beam may include a beam corresponding to the first paging indication response information and other beams in the cell, where the other beams may be all beams of the network device in the cell except the first beam, or adjacent beams of the beam corresponding to the first paging indication response information.
For another example, the identifier of the at least one beam recommended by the terminal device may include one or more beam identifiers, and the beam corresponding to the at least one beam identifier is one or more beams with better quality obtained by the terminal device through measurement. The network device may determine a first beam to transmit paging content based on the at least one beam identification. For example, the first beam may include a beam corresponding to the first paging indication response information and a beam corresponding to the identifier of the at least one beam recommended by the terminal device.
For example, the reference information may be transmitted by using different preambles, and the different preambles represent different reference information.
For example, the network device is configured with 3 preambles, which are 1, 2 and 3 respectively, where the 3 preambles may be used to respond to the paging indication information, if the reference information includes a speed attribute, the low-speed terminal device responds to the paging indication information with the preamble 1, the medium-speed terminal device responds to the paging indication information with the preamble 2, and the high-speed terminal device responds to the paging indication information with the preamble 3, in this way, the network device may determine the speed attribute of the terminal device responding to the paging indication according to the received different preambles.
According to the embodiment of the invention, the paging sending mode reference information is carried in the paging response indication information, so that the network equipment can determine whether to send the paging content on one or more beams related to the terminal equipment according to different paging sending mode reference information.
In another example, after the terminal device determines to respond to the paging indication information according to the paging indication information (step 203), before the terminal device transmits first paging indication response information to the network device (step 204), the method further includes:
203a, the terminal device determines the paging sending mode reference information according to the attribute of the terminal device, the type of the terminal device, and the identifier of at least one beam obtained by the terminal device measuring the beam quality.
Illustratively, the attribute of the terminal device includes a speed attribute or a mobility attribute.
Illustratively, the types of the terminal devices include vehicle-mounted devices, intelligent terminals or machine terminals.
Illustratively, the terminal device measures beams of a current cell, determines N beams with the best quality, and takes an identifier corresponding to at least one beam of the N beams except for a first beam as a recommended beam of the terminal device.
Therefore, different terminal devices can send different paging sending mode reference information, so that the network device can determine whether to send paging content on a plurality of beams related to the terminal device according to the different paging sending mode reference information.
In another example, after the terminal device sends the first paging indication response information to the network device (step 204), the method further comprises:
204a, the terminal device determines the starting time and/or the ending time for receiving the paging content according to the time corresponding to the paging indication information.
Wherein, the starting time of the paging content reception is N + S1, where N is the time corresponding to the paging indication information, and S1 is a predefined value or a value received from the network device; or, the ending start time of the sending of the paging indication information is N + E1, where N is a time corresponding to a paging indication, the E1 is a predefined value or a value received from the network device, and the E1 is greater than or equal to the S1. Wherein S1 is greater than or equal to the end time E of the paging indicator transmission, or wherein S1 is greater than or equal to the start time S of the paging indicator information transmission, wherein N, E1, S1 and S are positive numbers. The receiving time and/or the ending time of the paging content are determined, so that the terminal equipment can determine the sending time window for receiving the paging content, the terminal equipment is prevented from monitoring the paging content additionally, and the power consumption of the terminal equipment is reduced.
In another example, after the terminal device sends the first paging indication response information to the network device (step 204), the method further comprises:
204b, the terminal equipment determines the starting time and/or the ending time for receiving the paging content according to the time corresponding to the paging indication response information.
Wherein a start time of the paging content reception is N + S1, where N is a time corresponding to a paging indication response information, and S1 is a predefined value or a value received from the network device; or, the ending start time of the paging indicator transmission is N + E1, where N is the time corresponding to the paging indicator response, the E1 is a predefined value or a value received from the network device, and the E1 is greater than or equal to the S1. Wherein N, E1 and S1 are positive numbers. And defining the receiving time and/or the ending time of the paging content, so that the terminal equipment can determine the sending time window for receiving the paging content, and the terminal equipment is prevented from monitoring the paging content additionally, thereby reducing the power consumption of the terminal equipment.
In another example, prior to step 201, the method further comprises:
200a, the network device receives paging content sent by a core network device, where the paging content carries reference information used by the terminal device to determine a paging indication, and the network device determines, according to the reference information of the paging indication, that paging indication information includes paging information of at least one terminal device group.
Illustratively, the reference information includes paging indication packet information of the terminal device.
Illustratively, the reference information includes a terminal device identifier used by the terminal device to obtain the paging indicator. Such as an International Mobile Subscriber Identity (IMSI) of the terminal device or a Temporary Mobile Subscriber Identity (TMSI) of the terminal device.
Illustratively, the reference information includes a part of bits of the terminal device identifier corresponding to the paging indication. Such as the IMSI of the terminal device or a portion of the bits used in the TMSI of the terminal device.
Since the network device does not store the identifier of the terminal device for acquiring the paging packet, the network device cannot acquire the paging indication, and therefore, the network device needs to be notified from the core network device, thereby ensuring that the network device can acquire the paging indication.
In another example, prior to step 201, the method further comprises:
200b, the network device receives a paging message sent by a core network device, the paging message carries a paging identifier of the terminal device, and the network device determines that paging indication information includes a part of bits of the terminal device identifier according to the paging identifier.
The network device does not store the paging identifier of the terminal device for acquiring the paging packet, so that the network device cannot acquire the paging indication, and therefore, the network device needs to be notified from the core network device, and further, the network device can acquire the paging indication.
In another example, prior to step 201, the method further comprises:
200c, the network device receives reference information sent by the core network device, the reference information is used for obtaining reference information of paging indication for the terminal device, and the network device determines the paging indication information according to the reference information.
Illustratively, the reference information includes paging indication packet information of the terminal device. And the network equipment determines that the paging indication corresponding to the group is set to be paged in the paging indication according to the grouping information of the terminal equipment.
Illustratively, the reference information includes a terminal device identifier used by the terminal device to obtain the paging indicator. Such as the IMSI of the terminal device or the TMSI of the terminal device
Illustratively, the reference information includes a part of bits of the terminal device identifier corresponding to the paging indication. Such as the IMSI of the terminal device or a part of the bits of the TMSI of the terminal device
For example, the reference information may be carried in at least one of the following messages sent by the core network device to the network device: an initial context setup message, a context modification message, a handover message, a path switch message, or a path switch response message.
Illustratively, after receiving data or signaling corresponding to the terminal device sent by a core network device, the network device determines paging indication information according to the reference information.
The network device does not store the terminal device identifier for acquiring the paging packet, so that the reference information cannot be acquired, and therefore, the network device needs to be notified from the core network device, and further, the network device can acquire the paging indication.
In another example, the method further comprises:
207. and when the wave beam corresponding to the first paging indication response information changes, the terminal equipment sends second paging indication response information to the network equipment.
Illustratively, if the terminal device determines that the time window for sending the first paging indication response information is not expired, the terminal device sends the second paging indication response information to the network device. It should be noted that the content included in the second paging indication response information is similar to that included in the first paging indication response information, and is not described herein again. And the terminal equipment sends the second paging indication response message and needs to confirm a sending time window, and if the sending time window is expired, the terminal equipment cannot continue to send the paging indication. Even if the terminal device sends the paging indicator to the network device, the network device does not receive or incorrectly considers the paging indicator response as a response to other paging indicator information.
For example, the beam corresponding to the first paging indication response information may be a beam associated with a preamble resource used in the first paging indication response information sending process, for example, if the network device specifies that resource 1 corresponds to beam 1 and resource 2 corresponds to beam 2, the terminal device sends the paging indication response information by using different resources, which represents different corresponding beam information. For example, the resource may be a time-frequency resource set or a preamble resource combination. For example, preamble sets 1-10 represent corresponding beam 1, preamble sets 11-20 represent beam 2, the terminal device determines the preamble resource corresponding to the beam according to the best beam, and the preamble resource is used in the first paging response indication sending process. So that the network device can know the current best beam information of the terminal device. In this case, if the terminal determines that the beam associated with the used preamble resource will not be used continuously to receive the subsequent message in the first paging indication sending process (for example, the beam quality becomes poor, it is unable to continuously receive signals, or the beam is not the best beam of the current UE), it is determined that the beam corresponding to the first paging indication response information changes.
For example, the beam corresponding to the first paging indication response information may be a beam recommended by the terminal device in the first paging indication response information.
208. And the network equipment receives second paging indication response information sent by the terminal equipment, wherein the second paging indication response information is sent after the terminal equipment determines that a beam corresponding to the paging indication response information changes.
For example, the network device determines a time window for receiving the first paging indication information, and the network device receives the second paging indication response information sent by the terminal device within the time window.
209. And the network equipment determines a second beam according to the paging sending mode reference information carried in the second paging indication response information.
210. And the network equipment transmits the paging content to the terminal equipment through the second beam.
The second paging indication response information can enable the network device to know that the beam of the terminal device changes, so that the paging content is retransmitted according to the changed beam.
In another example, the method further comprises:
if the paging indication information received by the terminal equipment indicates that the paging indication group where the terminal is located is paged but does not receive paging content, sending paging check request information to the network equipment, wherein the paging check request information carries an identifier of the terminal equipment, and the identifier of the terminal equipment is used for the network equipment to determine whether the paging content of the terminal equipment exists according to the paging check request information of the terminal equipment. It should be particularly emphasized that the paging check request message is an example for better understanding of the technical solution of the present invention, and in practical applications, as long as the triggering network device can determine whether there is the paging content of the terminal device according to the request message, the present embodiment is within the scope to be protected.
The network device receives paging check request information sent by the terminal device, determines whether the paging content of the terminal device exists according to the paging check request information of the terminal device, and after the network device determines that the paging content of the terminal device exists, the network device sends the paging content on a wave beam corresponding to the paging check request information. The paging check information can enable the terminal to confirm whether the paging content is available for the terminal, so that the paging is prevented from being missed.
In another example, after the terminal device sends the first paging indication response information to the network device, the method further includes:
the terminal device determines a second beam for receiving paging content, and receives the paging content sent by the network device through the first beam on the second beam, where the second beam may be one of the first beams. Wherein the second beam is a beam corresponding to the paging indication response message. The first beam is a sending beam of the paging content determined by the network equipment according to the paging indication response message.

When a cell is covered by multiple beams, each cell needs to repeatedly transmit paging content on multiple beams, which results in waste of resources. Therefore, the prior art proposes an optimization scheme, that is, a network device divides terminal devices into a plurality of groups, and then sends a round of paging indication on all beams, where the paging indication carries information about whether terminal devices belonging to at least one group are paged, and since the indication does not need to carry a complete terminal device identifier, the paging indication is small. After receiving the paging indication, the terminal device determines whether the group in which the terminal device is located is paged, if the terminal device is paged, the terminal device initiates a paging response to the network device through the beam corresponding to the group, and the network device sends paging content to the terminal device through the beam corresponding to the paging response.
In the prior art, the sending time of the paging response information and the sending time of the subsequent paging content are not explicitly specified, which may cause different time periods for sending the paging response information by different terminal devices, thereby affecting the time period for sending the paging content by the network device. Moreover, due to reasons such as shielding of the terminal device, shielding of a beam, or movement of the terminal device, a beam corresponding to the terminal device when sending a paging response changes later, and the network device cannot timely acquire information that the beam corresponding to the paging response of the terminal device changes, so that the network device cannot effectively page the terminal device.
In order to solve the above technical problem, an embodiment of the present invention provides an information sending method, how to enable a network device to effectively page a terminal device.
Fig. 5 is a schematic flowchart of an information sending method according to an embodiment of the present invention, where the method includes:
501. and the network equipment sends paging indication information to the terminal equipment.
Illustratively, the paging information includes paging information of at least one terminal device group, and the paging information includes information on whether a first terminal device group is paged.
Illustratively, the paging indication information includes a part of bits of the terminal device identifier.
502. And the terminal equipment receives paging indication information sent by the network equipment and judges whether to respond to the paging indication according to the paging indication information.
The specific step of determining whether to respond to the paging procedure is similar to step 203 in the embodiment shown in fig. 2, and is not described herein again.
503. And the terminal equipment determines to respond to the paging indication and sends paging indication response information to the network equipment.
Illustratively, the sending, by the terminal device, paging indication response information to the network device includes: the terminal device determines the sending start time of the paging indication information and/or the sending end time of the paging indication information according to the time corresponding to the paging indication information, and the terminal device sends the first paging indication response information to the network device according to the sending start time and/or the sending end time.
The starting time of sending the paging indication response information is N + S, where N is the time corresponding to the paging indication information, and S is a predefined value or a value received from the network device, and may be, for example, a slot, a subframe, or a time unit; and/or the end time of sending the paging indication information is N + E, where N is the time corresponding to the paging indication information, and E is a predefined value or a value received from the network device, and is greater than or equal to S. For example, the time unit is a subframe, if the terminal device receives the paging indication information in the nth subframe, the time for the terminal device to send the paging indication response information is between an N + S subframe and an N + E subframe, where N, S and E are positive numbers.
It should be noted that, the time window for the terminal device to send the paging indication response message is between N + S and N + E, and if S ═ E, the time window for sending the paging indication response message has only one time unit, and the start time and the end time of the sent paging indication response message overlap at this time.
In one example, after the terminal device sends the first paging indication response information to the network device (step 503), the method further includes:
503a, the terminal device determines the starting time and/or the ending time for receiving the paging content according to the time corresponding to the first paging indication information.
It should be noted that, please refer to the relevant content in step 205 in the embodiment shown in fig. 2 for the time when the terminal device receives the paging content, which is not described herein again. By determining the receiving time and/or the ending time of the paging content, the terminal equipment can determine the sending time window for receiving the paging content, so that the network equipment can effectively page the terminal equipment, and in addition, the terminal equipment can be prevented from monitoring the paging content additionally, and the power consumption of the terminal equipment is reduced.
In one example, after the terminal device sends the first paging indication response information to the network device (step 503), the method further includes:
503b, the terminal device determines the starting time and/or the ending time for receiving the paging content according to the time corresponding to the first paging indication response information.
Wherein a start time of the paging content reception is N + S1, where N is a time corresponding to a paging indication response information, and S1 is a predefined value or a value received from the network device; or, the ending start time of the paging indicator transmission is N + E1, where N is the time corresponding to the paging indicator response, the E1 is a predefined value or a value received from the network device, and the E1 is greater than or equal to the S1. Wherein N, E1 and S1 are positive numbers. The receiving time and/or the ending time of the paging content are determined, so that the terminal equipment can determine the sending time window for receiving the paging content, the terminal equipment is prevented from monitoring the paging content additionally, and the power consumption of the terminal equipment is reduced.
In another example, before step 501, the method further includes receiving paging content or reference information sent by the core network device, where specific content is similar to steps 200a, 200b, and 200c in the embodiment shown in fig. 2, and is not described herein again. Since the terminal device does not store the relevant information for obtaining the paging indicator (for example, the reference information for determining the paging indicator by the terminal device, the paging indicator packet information of the terminal device, or the terminal device identifier for obtaining the paging indicator by the terminal device), by the method provided by this embodiment, the core network device notifies the terminal device of obtaining the relevant information for obtaining the paging indicator, so that the network device can effectively page the terminal device.
In another example, based on the foregoing embodiment, the method further includes further notifying the network device when the beam corresponding to the first paging indication response information changes, and a specific procedure is similar to steps 207 to 210 in the embodiment shown in fig. 2 and is not described herein again. By adopting the method provided by the embodiment, the second paging indication response information can enable the network device to know that the beam of the terminal device changes, so that the paging content is retransmitted according to the changed beam, and the network device can effectively page the terminal device.
In another example, the method further comprises: if the paging indication information received by the terminal device indicates that the paging indication group where the terminal is located is paged but does not receive paging content, sending paging check request information to the network device, where the paging check request information carries an identifier of the terminal device, where the identifier of the terminal device is used for the network device to determine whether the paging content of the terminal device exists according to the paging check request information of the terminal device, the network device receives the paging check request information sent by the terminal device, determines whether the paging content of the terminal device exists according to the paging check request information of the terminal device, and after determining that the paging content of the terminal device exists, the network device sends the paging content on a beam corresponding to the paging check request information. By adopting the method provided by the embodiment, the terminal equipment can confirm whether the paging content for the terminal equipment exists or not through the paging check information, so that the paging is avoided being missed.
In another example, the method further comprises: the terminal device determines a second beam for receiving paging content, and receives the paging content transmitted by the network device through the first beam on the second beam, wherein the first beam comprises the second beam. The second beam is a beam corresponding to the paging indication response message. The first beam is a sending beam of the paging content determined by the network equipment according to the paging indication response message.
