Referring to fig. 2, fig. 2 is a flowchart of a paging listening method according to an embodiment of the present invention, where the method is applied to a UE, and as shown in fig. 2, the method includes the following steps:

step 201, if the UE cannot monitor the first paging location, the UE monitors the second paging location, where the first paging location meets a first condition, and the second paging location meets a second condition, and the first condition is different from the second condition.

The first paging location may be a paging location where the UE collides with another UE, where the colliding paging location may be a paging location where two UEs overlap, or a paging location where an interval between two UEs is smaller than a preset threshold. For example: there is overlap between the PO of UE1 and the PO of UE2 as shown in fig. 3, or the PO of UE1 and the PO of UE2 are separated by less than a certain threshold.

If the UE cannot monitor the first paging location, the UE monitors the second paging location, which means that if the UE cannot monitor the first paging location, it is ensured that paging is monitored at the second paging location, and paging loss is reduced.

The first paging location may include a paging location (PO) in a DRX cycle satisfying a first condition among all non-connection reception (DRX) cycles of the UE or a PO in a PF satisfying the first condition among all PFs of the UE; the second paging location may include a paging location within a DRX cycle satisfying the second condition in all DRX cycles of the UE or a PO within a PF satisfying the second condition in all PFs of the UE.

It should be noted that the two UEs may be two SIMs in a terminal supporting multiple SIMs (i.e., a multi-card terminal), or UEs corresponding to the two SIMs. In addition, for a scenario of a terminal supporting multiple SIMs, in the embodiment of the present invention, UE1 and UE2 may be used to represent two UEs of the terminal supporting multiple SIMs, and the UE in step 201 may be any UE of the terminals supporting multiple SIMs.

The first condition and the second condition may be pre-configured by the network side, or pre-agreed by the protocol, or two different conditions determined by the terminal. For example: the Paging Frame (PF) corresponding to the Paging position satisfies the condition, that is, the PFs corresponding to the first Paging position and the second Paging position respectively satisfy different conditions.

By the first condition and the second condition, the UE can monitor paging at the paging position meeting the second condition when the paging position meeting the first condition cannot monitor paging, so that the monitoring performance of the UE is improved.

As an alternative embodiment, the first condition and the second condition are different, and the first condition and the second condition are different:

the first condition is that a quotient of the PF of the UE divided by the discontinuous reception period T of the UE is an even number, and the second condition is that a quotient of the PF of the UE divided by the T of the UE (i.e., PF div T) is an odd number; or

The first condition is that a quotient of the PF of the UE divided by the T of the UE is an odd number, and the second condition is that a quotient of the PF of the UE divided by the T of the UE is an even number; or

The first condition is that a quotient obtained by dividing the PF of the UE by the T of the UE and then performing modulo N (namely, (PF div T) mod N) is a first value or belongs to a first set, the second condition is that a quotient obtained by dividing the PF of the UE by the T of the UE and then performing modulo N is a second value or belongs to a second set, and the N value is an integer related to the paging monitoring period of the UE;

wherein the first value is different from the second value, the first set is different from the second set, the first set does not include the second value, and the second set does not include the first value.

The quotient of the PF divided by the drx cycle T of the UE may be a quotient of a radio Frame Number (SFN) for paging the UE and the drx cycle T of the UE, i.e., SFN div T corresponding to the PF of the UE.

The N may be a Discontinuous Reception (DRX) paging cycle ratio of a plurality of UEs in which the multi-card terminal has a paging collision; alternatively, the N may be a paging listening period customized for the UE, for example: the UE monitors paging once every N T in all paging positions, wherein N is the paging monitoring period. Of course, N may also be configured or agreed by the network side.

The first condition is that a quotient of the paging frame PF of the UE divided by the discontinuous reception cycle T of the UE is an even number, and the second condition is that a quotient of the PF of the UE divided by the T of the UE is an odd number may mean that the second paging position is located after the first paging position, and the discontinuous reception cycle in which the first paging position is located is adjacent to the discontinuous reception cycle in which the second paging position is located. The first condition is that a quotient of the PF of the UE divided by the T of the UE is an odd number, and the second condition is that a quotient of the PF of the UE divided by the T of the UE is an even number may also mean that the second paging position is located after the first paging position, and a discontinuous reception cycle in which the first paging position is located is adjacent to a discontinuous reception cycle in which the second paging position is located.

The first value, the second value, the first set, and the second set may be pre-configured by the network side, or agreed by a protocol, or determined by the multi-card terminal, or determined by the UE.

In this embodiment, if the UE cannot monitor at the even paging location, the UE monitors at the odd paging location, if the UE cannot monitor at the odd paging location, the UE monitors at the even paging location, and if the UE cannot monitor at the first value or the paging location corresponding to the first set, the UE monitors at the second value or the paging location corresponding to the second set, so as to improve the probability that the terminal monitors the paging. Furthermore, the network side can also page the UE according to the rule so as to reduce the frequency of paging sent by the network side and save resources.

Optionally, the method further includes:

and if the UE determines that the first paging position cannot be monitored, the UE reports first information to a network side, wherein the first information is used for indicating that the UE has the paging position which cannot be monitored.

The reporting of the first information may be reporting to a core network element or a second access network element, and the reporting may be reporting before the step 201 is executed, or reporting while the step 201 is executed, or reporting after the step 201 is executed. And the first information may be an implicit or explicit indication that the UE has a paging location that cannot be listened to.

Further, the UE may report the first information through any one of the following messages:

a Radio Resource Control (RRC) connection establishment request message, an RRC connection restoration request message, an RRC reconfiguration complete message, and a registration request.

By the message reporting, additional messages can be avoided, and transmission resources can be saved. Of course, in the embodiment of the present invention, the first information may also be reported through a dedicated message.

In this embodiment, since the first information is reported to the network side, the network side can notify the UE of the existence of the paging location that cannot be monitored in time, so that the UE can monitor the paging location for paging, thereby saving resources.

Optionally, the first information includes at least one of:

paging enhancement indication, paging conflict indication and paging position related information.

The paging enhancement indication may be used to indicate that the UE is paged in an enhanced manner or indicate that the UE has a paging location that cannot be monitored, that is, the UE is paged according to the paging method provided in the embodiment of the present invention.

The paging conflict indication may be used to indicate that the UE has a paging location conflict or indicate that the UE has a paging location that cannot be monitored, that is, a paging location that cannot be monitored exists.

It should be noted that the paging enhancement indication and the paging collision indication may also be referred to by other names, which do not limit the embodiment of the present invention, for example: paging location assistance information, etc.

Optionally, the information related to the paging location includes at least one of:

paging location information that the UE cannot monitor;

paging location information normally monitored by the UE;

information related to the first condition;

at least one of the first value, the second value, the first set, the second set, and the value of N.

The paging location information normally monitored by the UE may be a paging location that the UE can monitor.

The information related to the first condition may be information related to a first condition for indicating that the first paging location is satisfied, for example: indication information indicating parity of a quotient of a PF corresponding to a first paging location divided by a T of the UE; or indicating the PF corresponding to the first paging position divided by the quotient of the T of the UE and then obtaining the result of the modulus of the N.

Through the related information of the first condition, the network side can accurately identify the paging position which the UE cannot monitor.

In addition, the value N may be used to determine a paging listening period of the UE, the information related to the first condition may be used to determine a paging location that the UE cannot listen to, the first value, the first set, and the value of N are used to determine a paging location that the UE cannot listen to, and the second value, the second set, and the value of N are used to determine a paging location that the UE normally listens to.

The first value, the first set and the value of N may be used to determine a paging location that the UE cannot monitor, any one of the first value, the first set and the value of N may be used to determine a paging location that the UE cannot monitor, the second value, the second set and the value of N may be used to determine a paging location that the UE cannot monitor, and any one of the second value, the second set and the value of N may be used to determine a paging location that the UE normally monitors.

In this embodiment, the network side can accurately determine the paging location of the UE through the relevant information of the paging location.

The following describes an embodiment of reporting the first information, where the multi-card terminal includes a UE1 and a UE2, where the above is one of the UE1 and the UE 2:

first, the UE1 and/or the UE2 determine whether the first information needs to be reported according to a paging listening policy of the multi-card terminal.

The paging cycle values of the UE1 and the UE2 may be one of 320, 640, 1280, 2560ms and …, and the paging cycles of the UE1 and the UE2 may be the same or different. For convenience of description, hereinafter, it is assumed without loss of generality that the paging cycle of the UE1 is equal to or longer than the paging cycle of the UE 2.

The multi-card terminal detects that the PO collision occurs between the UE1 and the UE2, and the multi-card terminal may adopt the following paging monitoring policy:

when the paging cycle of the UE 1/the paging cycle of the UE2 is 1, the multi-card terminal alternatively monitors the paging collision location;

when the paging cycle of UE 1/paging cycle of UE2 is 2, 4, 8, the multi-card terminal always listens to the PO of UE1 in the paging collision location.

This may be particularly shown in figure 4.

The UE1 and/or UE2 determine whether there is a PO that cannot be monitored according to the paging monitoring policy of the multi-card terminal, which is specifically as follows:

UE 2: as long as the paging cycle is less than or equal to the UE1, there will be a PO that cannot monitor paging;

UE 1: there is a PO that cannot listen for a page only if UE1 paging cycle/UE 2 paging cycle is 1;

the UE that cannot monitor part of the PO locations may report the first information, for example, a paging collision occurs.

The time when the UE1 and/or the UE2 report the first information may be as follows:

once it is found that there is a PO that cannot be listened to, the UE1 and/or the UE2 report the first information to the network where it is located at a proper time, which is only UE2 as an example:

UE2 is in idle state: initiating RRC connection establishment in the currently camped cell,

carrying first information such as paging collision indication (paging collision) or paging enhancement indication (e.g. enhancement IE) or paging location indication information in an RRC setup complete (RRCSetupComplete) message; after the first information is read by the gNB, the information is sent to the AMF2 together with other NAS layer parameters of the UE2 (such as UE 25G-S-TMSI) in an NG message; or

Setting an establishment cause (estabilishment cause) in an RRC establishment request (RRCSetuprequest) message to be 'PaginCollision', when the gNB acquires the value of the estabilishment cause, indicating paging conflict of the UE2 to the AMF2 through an NG interface, and then the gNB can set the UE2 to be in an idle state (sending RRCRject) or a connection state (sending RRCSetup); or

When the UE2 is in the inactive state: and initiating RRC connection recovery in the current resident cell:

setting a recovery reason (resummebause) in an RRC recovery request (RRCResemerRequest) message to be 'PaginCollision', when the gNB acquires a resummebause value, indicating a paging conflict of the UE2 to the AMF2 through an NG interface, and then setting the UE2 to be in an inactive state (sending RRCRelease with suspend) or a connected state (sending RRCReseume); or

When UE2 is in the connected state:

a paging conflict triggered by the network, for example, after the gNB sends RRC reconfiguration (rrcreeconfiguration), the gNB indicates the UE2 to detect whether the paging conflict exists, and the UE2 reports a result in a UE assistance information (ueassistestanceinformation) message or reports an RRC reconfiguration complete message; or

Reporting paging collision triggered by the UE2 actively, if there is collision, reporting in an RRC reconfiguration complete (rrcreconfigurable complete) message or other dedicated signaling (e.g., paging collision report);

in the embodiment of the invention, if the UE cannot monitor the first paging position, the UE monitors the second paging position, the first paging position meets a first condition, the second paging position meets a second condition, and the first condition is different from the second condition. Therefore, the UE can monitor the second paging position when determining that the UE cannot monitor the first paging position, and the paging message receiving or paging monitoring performance of the UE is improved.

Referring to fig. 5, fig. 5 is a flowchart of a paging method according to an embodiment of the present invention, where the method is applied to a network element of a first access network, and as shown in fig. 5, the method includes the following steps:

It should be noted that, this embodiment is used as an implementation of a core network element or a second access network element corresponding to the embodiments shown in fig. 2 and fig. 3, and a specific implementation thereof may refer to the relevant description of the embodiment shown in fig. 2, so as to avoid repeated description, and this embodiment is not described again. In this embodiment, the paging reception monitoring performance of the UE may also be improved, for example, the paging message reception or paging message monitoring performance is improved.

The method provided by the embodiment of the present invention is exemplified below by taking the UE2 with the UE as a multi-card terminal, where the AMF2 triggers sending of a paging message when a core network pages (CN paging), or triggers sending of a paging message by a serving RAN network element (gNB/eNB) when an access stratum pages (RAN paging):

example 1:

in this embodiment, the paging is CN paging, and the AMF indicates parity through the second information, including the following steps:

step 1: the AMF2 receives a first message sent by the gNB to the NG interface, wherein the first message comprises first information used for indicating that the UE2 has paging conflict or needs paging enhancement, namely, a paging position which cannot be monitored exists;

step 2: when the UE2 (in idle state) has downlink data to reach the UPF, the AMF2 is triggered to page the UE 2. The AMF2 sends a second message (i.e. a first paging message) to part or all of the gnbs in the tracking area list (TA list) of the UE2 through the NG interface, where the second message carries second information, such as paging location indication information;

and step 3: and the gNB receives the first paging message sent by the AMF2 and performs one of the following steps:

if paging location indication information is not present, the gNB does not page the UE2 using paging enhancements;

when the paging location indication information appears and is a third value, indicating that the gNB pages the UE2 when (SFN div T of PF) is an even number;

when the paging location indication information appears and is a fourth value, indicating that the gNB pages the UE2 when (SFN div T of PF) is odd;

and 4, step 4: and the AMF2 does not receive the paging response of the UE2, and then the paging is initiated again. At this time, a second paging message, which may be a retransmission of the first paging message described above, is sent to part or all of the gNB in the TA list of the UE2, where the value of the paging location indication information in the second paging message is different from the last time, for example: and performing negation operation, wherein the paging position indication information is not carried last time and is carried this time.

And 5: the UE2 listens for the PO using:

paging the non-conflicted PO, and normally monitoring by the UE 2;

in paging a conflicting PO, if the conflicting PO is odd, the UE2 listens on the following even PO, and vice versa;

step 6: when AMF2 pages UE2 successfully, there may be two options:

firstly, storing the current paging position indication information so as to facilitate the next paging to use the value;

deleting the current paging position indication information;

further, this embodiment and the following embodiment 2 can also be extended to a general scenario, that is, step 4 uses the following more general expression:

when the paging position indication information is the value X, the gNB pages the UE2 when the value of (SFN div T of PF) mod N is Y, wherein Y is 0,1,2, …, N-1; n is pre-configuration or protocol agreement; y and the 'X value' have a corresponding relation; for example, the parity above is taken as an example, where N ═ 2 and X ═ Y ═ 0 are specific examples: when the paging location indication information value is 0, the gNB is instructed to page the UE2 at an even location, which refers to the corresponding PF when (PF div T) is even.

Example 2:

in this embodiment, the paging is RAN paging, and the serving gbb indicates parity through the second information, including the following steps:

step 1: when the UE2 is in an RRC inactive state and downlink messages or data arrive at the serving gbb of the UE2 in the core network, the serving gbb sends a first paging message to all or part of the serving gbb in the notification area through an Xn interface, where the first paging message carries second information, such as paging location indication information;

step 2: after receiving the paging message sent by the serving gNB, the gNB in the notification area executes one of the following:

when the paging location indication information value is 0, indicating the gNB to page the UE2 at an even location;

when the paging location indication information value is 1, indicating the gNB to page the UE2 at an odd number of locations;

and 4, step 4: when the serving gNB does not receive the paging response of the UE2, the paging is reinitiated, and at this time, when a second paging message is sent to all or part of gNB in the notification area of the UE2, the paging position indication information values in the second paging message and the first paging message are different from the last time;

and 5: the UE2 listens for the PO using:

paging the non-conflicted PO, and normally monitoring by the UE 2;

step 6: when serving the gNB pages the UE2 successfully, there may be two options:

firstly, saving the current paging position indication information value so as to be convenient for the next paging to use the value;

and secondly, deleting the current paging position indication information value.

Example 3:

in this embodiment, the Paging is CN/RAN Paging, and the parity is indicated by a Paging Attempt counter (Paging attemptcount), including the following steps:

step 1: when the AMF 2/serving gNB pages the UE2, sending a first Paging message to all or part of the gNB within the TA list/notification area of the UE2 through the NG/Xn interface, wherein the first Paging message includes a Paging Attempt counter (Paging at Count) and/or a Paging enhanced indication;

and step 3: after receiving the first paging message, the gNB executes one of the following:

when the paging attempt counter value is even, then the gNB is instructed to page the UE2 at an even location;

when the paging attempt counter value is odd, then the gNB is instructed to page the UE2 at an odd location;

as a preferred embodiment, only when the first paging message carries: when a paging enhancement indication or the content of the paging enhancement indication is set as an agreed value, the gNB indicates one of the two operations.

And 4, step 4: after the AMF 2/serving gbb does not receive the paging response of the UE2, the paging is re-initiated, and at this time, a second paging message, which may be a retransmission of the first paging message, is sent to all or part of the gbb in the TA list/notification area of the UE2, where the paging attempt counter value is incremented once;

and 5: the UE2 listens for the PO using:

paging the non-conflicted PO, and normally monitoring by the UE 2;

step 6: when AMF 2/serving gNB pages UE2 successfully, there may be two options:

firstly, the parity of the current paging counter is saved so that the value can be used in the next paging;

secondly, deleting the parity of the current paging counter;

without loss of generality: when (paging attempt counter value mod N) ═ X, the gNB transmits a page at a PF whose value Y satisfies (SFN div T of PF) mod M; n, M, X and Y are protocol convention or network configuration; a preferred implementation: m and N will be set to be the same; x and Y are set to be the same.

Example 5:

in the embodiment, the paging is CN/RAN paging, and the operation of paging position inversion is executed according to the indication information in the paging message of the NG/Xn interface

Step 1: when the AMF 2/serving gNB pages the UE2, a first paging message is sent to all or part of gNB in a TA list/notification area of the UE2 through an NG/Xn interface, wherein the first paging message comprises paging position indication information;

when there is no a priori information (e.g., UE2 has not been paged before), configuring the paging location indication information value to be 0 or not configuring the paging location indication information;

when the AMF 2/serving gNB stores prior information (when the UE2 is paged last time successfully), configuring the paging position indication information value to be 0;

when AMF 2/serving gNB fails to page UE2, configuring the paging position indication information value to be 1;

and step 3: after receiving the second message, the gNB executes one of the following:

if paging location indication information is present, the gNB uses the paging enhancements to page the UE 2. First, the paging location information of this time, i.e. parity of (PF _ last div T), or PF (PF _ last) of the last paging, is saved for prior information of the next paging UE 2;

if the paging location indication information value is 0, if the gNB does not store the paging location information of the last paging UE2, the UE2 may be paged at any paging location of the UE2, or if the gNB stores the paging location information of the last paging UE2, the parity of the current (PF div T) is consistent with the previous one;

if the paging location indicator information value is 1, the parity of the current (PF div T) of the gNB is opposite to the previous parity.

And 4, step 4: the UE2 listens for the PO using:

paging the non-conflicted PO, and normally monitoring by the UE 2;

step 6: when AMF 2/serving gNB pages UE2 successfully, there are two options:

firstly, the parity of the current paging position is saved so that the value can be used in the next paging;

and secondly, deleting the parity of the current paging position.

In an extensible manner, in the above embodiment, when the paging location indication information value received by the gNB is 0, the UE may be paged at the paging location corresponding to the first set, and when the paging location indication information value is 1, the UE may be paged at the paging location corresponding to the second set. The first and second sets can be realized by network configuration, terminal reporting and protocol agreement.

Example 6:

in this embodiment, the Paging is CN/RAN Paging, and the gNB determines to execute a Paging location negation operation according to a Paging Attempt counter (Paging at Count) of the NG/Xn interface, including the following steps:

step 1: when AMF 2/serving gNB pages UE2, send a first Paging message, which includes a Paging Attempt counter (Paging Attempt Count), to all or part of gNB in TA list/notification area of UE2 through NG/Xn interface;

step 2: and the gNB receives the second message and executes one of the following steps:

when the paging counter value is 0, then the gNB may page at the paging location of any UE2 and save this paging location information, i.e., (PF _ last div T) parity, or PF _ last, a priori information for the next paging of UE 2;

when the paging counter value is not 0, which means that the paging message is a retransmitted paging message, the gNB negates the parity of the current (PF div T) with the previous paging according to the stored paging location information of the previous paging UE2, and stores the paging location information of the current time;

and step 3: after finding out that the paging of the UE2 fails, the AMF2 restarts the paging, and at this time, when a second message is sent again to all or part of Gnb in the TA list/notification area of the UE2, the value of the paging attempt counter is increased once;

and 4, step 4: the UE2 listens for the PO using:

paging the non-conflicted PO, and normally monitoring by the UE 2;

and 5: when AMF 2/serving gNB pages UE2 successfully, there are two options:

and secondly, deleting the parity of the current paging counter.

In the above embodiments, for CN/RAN paging, the UE2 may not be required to report the first information (e.g., report paging collision) and/or the network side does not save the paging location information, for example:

the AMF2 uses paging enhancement mode to page the UE2, and does not depend on whether the AMF2 receives the paging enhancement indication information of the UE2, for example, the AMF2 may try not to use paging enhancement mode to page the UE2 without knowing, and try to use paging enhancement after paging failure. Alternatively, the UE2 is always paged using paging enhancements with knowledge.

Further, in the above embodiment, the UE2 may also not report the first information (e.g., report paging collision), then the CN-triggered paging and/or the RAN-triggered paging are performed in a paging enhanced manner for one or more transmissions of the same paging message, and after the UE is paged successfully, the network side does not store the paging location information, i.e., only transmits the paging location information once.
