When the UE is in the inactive state, when a new downlink data packet or NAS information is transmitted, the core network may directly send a paging message to the serving base station of the cell where the UE finally resides. The serving base station will page all its covered cells and at the same time will send paging messages to the neighbourhood based on the RNA range through the Xn interface.

Fig. 1 is a flowchart of a paging method according to an embodiment of the present application, where the paging method may be used for a network device, and the network device is a serving base station where a target cell last camped on before a first terminal enters an inactive state. As shown in fig. 1, the paging method may include the steps of:

step 101, acquiring the residence time of a first terminal in a target cell.

Specifically, the camping duration may refer to an actual length of the camping time of the target cell that was camped last before the first terminal enters the inactive state.

And 102, if the residence time is greater than a set threshold, sending a first paging message according to a priority paging mode, wherein the first paging message is used for indicating the first terminal to be converted from the inactive state to the connected state.

Specifically, the set threshold may be a viscosity time threshold set in advance. If the residence time is longer than the set threshold, the first terminal is possibly a user with low activity, namely a user with high mobility; if the residence time is less than or equal to the set threshold, it indicates that the first terminal may be a user with high mobility. Wherein the sticky time threshold may be adjusted according to the terminal residence data collected by the serving base station. Such as: the sticky time threshold may be increased when too many users enter priority paging for paging, and decreased otherwise.

The serving base station may page according to a priority paging pattern for less active users. Such as: and paging the first priority neighbor set, paging the second priority neighbor set after the paging is overtime, paging the third priority neighbor set after the paging is overtime, and so on until a paging response is received.

It can be seen from the foregoing embodiments that, by obtaining the residence time of the first terminal in the target cell, and if the residence time is greater than the set threshold, sending the first paging message according to the priority paging mode, where the first paging message is used to indicate that the first terminal is switched from the inactive state to the connected state, an optimal paging mode can be selected according to the residence time of the terminal, which not only improves the paging flexibility, but also improves the paging efficiency, saves air interface resources, and reduces signaling overhead.

Optionally, the obtaining the residence time length of the first terminal in the target cell includes:

Specifically, the condition for triggering paging may be that the serving base station receives a second paging message, which is sent by the core network device and is addressed to the first terminal, where the second paging message may include downlink data information or NAS information addressed to the first terminal.

It can be seen from the above embodiments that, when the serving base station detects the condition for triggering paging, instead of directly initiating paging, the serving base station first obtains the residence time of the first terminal in the target cell, and then selects the optimal paging mode according to the residence time, thereby avoiding huge signaling overhead, excessive radio resource occupation, and virtual consumption of air interface resources caused by the serving base station sending a large amount of paging messages within a certain range.

Optionally, the sending the first paging message according to the priority paging mode includes:

and sequentially sending the first paging message to the corresponding neighbor cell set according to the sequence of the priority from high to low.

Specifically, the setting rule may be a rule that the serving base station sets a set of areas with different priorities in advance according to actual conditions. Such as: and switching success times and/or paging response times of the first terminal in a set measurement period.

The serving base station may set 2 neighbor cell sets with different priorities, such as: the first priority neighbor cell set and the second priority neighbor cell set, wherein the first priority is higher than the second priority; it is also possible to set 3 neighbor cell sets with different priorities, such as: the first priority neighbor cell set, the second priority neighbor cell set and the third priority neighbor cell set, wherein the first priority is higher than the second priority, and the second priority is higher than the third priority.

When the first paging message is sent, the first paging message may be sent to the neighboring cell set with the highest priority, and after the paging is overtime, the first paging message may be sent to the neighboring cell sets with lower priorities until the paging response is received.

It can be seen from the above embodiments that the first paging message may be sequentially sent to each neighboring cell set according to the order of priority from high to low, thereby improving paging flexibility, improving paging efficiency, saving air interface resources, and reducing signaling overhead.

Optionally, the setting, according to a set rule, at least two neighboring cell sets with different priorities includes:

Specifically, the setting condition may be that a Radio Access Network-based Notification Area Code (RANAC) of the neighboring cell is the same as an RANAC of the target cell; or, a Public Land Mobile Network (PLMN) of the neighboring cell is the same as the PLMN of the target cell; or the RANAC and the PLMN of the neighboring cell are respectively the same as the RANAC of the target cell and the PLMN of the target cell.

The serving base station may set a measurement period (i.e., an adjacent cell priority measurement period) first, and then divide the adjacent cell priority set according to a measurement result in the measurement period (i.e., the adjacent cell priority measurement period), where the division may be based on the number of successful handover times and/or the number of paging responses of the first terminal in the measurement period (i.e., the adjacent cell priority measurement period).

According to the embodiment, the neighbor cell sets with different priorities can be divided according to the switching success times and the paging response times of the first terminal in the neighbor cell priority measurement period, so that the reliability of dividing the neighbor cell sets is improved.

Optionally, the setting, according to the number of successful handovers and/or the number of paging responses, at least two neighboring cell sets with different priorities includes:

Specifically, if the serving base station sets 2 neighboring cell sets with different priorities, that is, a first priority neighboring cell set and a second priority neighboring cell set, the process of dividing the neighboring cells is as follows: if one of the switching success times and the paging response times is larger than a set threshold value, adding the corresponding adjacent cell to a first priority adjacent cell set (namely, high priority); the neighbors beyond that are added to the second priority neighbor set (i.e., low priority).

If the serving base station sets 3 neighbor cell sets with different priorities, namely a first priority neighbor cell set, a second priority neighbor cell set and a third priority neighbor cell set. The process of dividing the neighboring cells is as follows: if one of the switching success times and the paging response times is larger than a set threshold value, adding the corresponding adjacent cell to a first priority adjacent cell set (namely, the highest priority); if the switching success frequency and the paging response frequency are both less than or equal to a set threshold and greater than 0, adding the corresponding adjacent region to a second priority adjacent region set (namely, a second priority); and if the switching success times and the paging response times are both equal to 0, adding the corresponding neighbor cell to the third priority neighbor cell set (low priority).

As can be seen from the foregoing embodiments, the neighboring cell set with the highest priority may include a neighboring cell whose handover success frequency is greater than a first set threshold, a neighboring cell whose paging response frequency is greater than a second set threshold, and the like, that is, the probability that the user moves to the neighboring cell is highest, so that paging is preferentially performed on the neighboring cell set with the highest priority, which can improve the accuracy of paging, improve the success rate of first paging, and reduce the virtual consumption of air interface resources.

Optionally, the paging method may further include:

Specifically, for a user with high mobility, a first paging message is not sent according to a priority paging mode; but rather pages within the coverage area of the serving base station and pages over the Xn interface.

It can be seen from the above embodiments that, for a user with high mobility, paging can be performed in the coverage area of the serving base station, and paging can be performed through the Xn interface, so that the success rate of first paging can be improved.

Optionally, the paging method may further include:

Specifically, when the first terminal returns from the inactive state to the connected state, an intra-base station supplementary symbol (i.e., paging supplementary signal) is added, and when it returns to the cell in the last camped cell or serving base station, the first terminal reports the intra-base station supplementary symbol (i.e., paging supplementary signal) to the serving base station.

It can be seen from the above embodiments that the paging auxiliary signal can indicate that the first terminal has switched from the inactive state to the connected state, which is convenient for the serving base station to adjust the paging mode in time and improves the paging efficiency.

Optionally, the receiving a paging assistance signal sent by the first terminal includes:

Specifically, in reporting, the first terminal may report an intra-base station assistance signal (i.e. paging assistance signal) through an interface message in the random access message, for example: and reporting through a physical layer interface message, a data link layer interface message or a network layer interface message in a random access message 3 (Msg 3) and a random access message 5 (Msg 5).

It can be seen from the above embodiments that the paging auxiliary signal can be obtained through the random access message, and the flexibility of paging is improved.

Optionally, the paging method may further include:

Specifically, after the serving base station determines that the first terminal has switched from the inactive state to the connected state, if the paging message sent by the core network device is received again, the serving base station may directly perform paging in the cell in the serving base station without performing paging through the Xn interface. And when the paging is overtime, paging is carried out according to the priority paging mode.

It can be seen from the above embodiments that, after determining that the first terminal has switched from the inactive state to the connected state, the first terminal may directly perform paging in the cell in the serving base station without performing paging through the Xn interface until the paging time is out, and then perform paging according to the priority paging mode, thereby improving the paging efficiency.

The above paging procedure is specifically described below by way of a specific example:

as shown in fig. 2, the base station sets a sticky time threshold, and compares the actual residence time of the terminal with the set sticky time threshold, so as to estimate the mobility of the terminal.

For a user with high mobility, namely when the residence time of the terminal is less than or equal to the set viscosity time threshold, the base station can perform paging in the coverage area of the base station and perform paging through an Xn interface, so that the success rate of first paging is improved.

For the users which are not active, namely when the residence time of the terminal is longer than the set sticky time threshold value, the base station carries out paging according to the priority paging mode.

When the base station pages according to the priority paging mode, a neighbor cell priority measurement period is set first, and the base station divides a neighbor cell priority set in the set measurement period. Such as: the base station divides the adjacent regions into three sets, wherein the nearest gNB is a first priority adjacent region set, the low priority gNB is a second priority adjacent region set, and other gNBs are third priority adjacent region sets. The neighbor list division condition is, as shown in fig. 3:

(1) First priority neighbor set (i.e., nearest gNB): the adjacent base station with the successful times of the effective switching of the terminal in the measuring period being higher than the threshold value and the adjacent base station with the paging response times being higher than the threshold value are paged; the neighbor base station where the terminal resides last time and the neighbor base station where the terminal is successfully switched last time;

(2) Second priority neighbor set (low priority gbb): measuring adjacent base stations with the switching times and the paging response times lower than the threshold value and higher than 0 in the period;

other neighbor gnbs: other contained neighbor cells meeting the conditions;

(3) And the priority set of each neighboring cell of the third priority neighboring cell set (namely other gNB) is also modified in real time according to the statistical condition of the next measurement period, and the neighboring base station where the UE resides last time and the neighboring base station where the UE is successfully switched last time are directly added to the nearest gNB.

And after the division of each priority adjacent region of the base station is finished, paging is carried out aiming at each set range. The paging rule is as follows: paging a first priority neighbor set (i.e., the nearest gNB) for the first time; when the paging is overtime, paging of a second priority neighbor cell set (low priority gNB) is carried out; when the paging is overtime, the paging of the third-priority neighbor set (low-priority gNB) is performed, and the specific flow is shown in fig. 4. And the priority set of each neighboring cell is also modified in real time according to the statistical condition of the next measurement period, and the neighboring cell where the UE resides last time and the neighboring cell where the UE is successfully switched last time are directly added into the first priority neighboring cell set (namely the nearest gNB).

When the terminal recovers from the inactive state to the connected state, the auxiliary symbol information (i.e., paging auxiliary signal) in the base station is added, and when the terminal reports in the cell that resides at the last or in the serving base station, the terminal may report through the interface message in the random access message, such as the physical layer interface message, the data link layer interface message, or the network layer interface message in the random access message 3 (Msg 3) or the random access message 5 (Msg 5), as shown in fig. 5.

The base station, upon receiving the paging assistance signal, records the paging assistance signal. After the base station counts the paging auxiliary signals for three times continuously, when the base station receives the paging message of the core network again, the cell in the base station directly sends the paging message to the terminal without informing other priority adjacent cells through an Xn interface. And paging the neighboring cells according to the priority after the paging is overtime, and if the neighboring cells responded by the paging method are not in the first priority neighboring cell set, directly adding the neighboring cells into the first priority neighboring cell set, wherein the process is shown in fig. 6. Meanwhile, the neighbor cell sets are evaluated in each measurement period, cells meeting the conditions in each set are added, and cells not meeting the conditions in each priority set are deleted.

Therefore, through the paging process, the paging efficiency of the base station can be improved, the paging blockage is effectively avoided, and the service quality such as telephone traffic and the like is improved; unnecessary empty resource waste and signaling overhead are reduced; the success rate of the first paging of the base station is improved; reduce the paging burden, etc.
