Before explaining the embodiments of the present disclosure in detail, an application scenario of the embodiments of the present disclosure will be described. Conventionally, when a UE is in an inactive state, a base station needs to know the notification area where the UE is located, but the notification area where the UE is located may be changed at any time due to the characteristic of the UE moving. However, it is not clear how the UE initiates notification area update in the inactive state, so that the base station cannot know the notification area of the UE in the inactive state. Therefore, the embodiment of the present disclosure provides a notification area updating method, by which a UE can update a notification area where the UE is located, and simultaneously notify the updated notification area to a base station, so that the base station knows the notification area where the UE is located in an inactive state.

All the above optional technical solutions can be combined arbitrarily to form optional embodiments of the present disclosure, and the embodiments of the present disclosure are not described in detail again.

Fig. 2 is a flowchart illustrating a notification area updating method according to an exemplary embodiment, which is used in a base station, as shown in fig. 2, and includes the following steps.

In step 201, a first notification area update request sent by the UE is received, where the first notification area update request carries a first cell identifier and a base station identifier of a base station accessed when a notification area is updated last time, and the first cell identifier is a cell identifier currently performing notification area update.

In step 202, when the base station identifier is different from the identifier of the base station, obtaining the context of the UE from the base station corresponding to the base station identifier;

in step 203, a permission update notification is sent to the UE based on the context of the UE and the first cell identity, and the permission update notification is used for instructing the UE to update the notification area based on the first cell identity.

In this embodiment of the present disclosure, when receiving a first notification area update request sent by a UE, a base station may send an update permission notification to the UE by obtaining a context of the UE and a first cell identifier carried in the first notification area update request, so as to instruct the UE to update a notification area based on the first cell identifier, thereby implementing an operation of updating the notification area when the notification area where the UE is in an inactive state is changed.

receiving a second notification area update request sent by the UE, wherein the second notification area update request carries a third cell identifier and a base station identifier of a base station accessed when the notification area is updated last time, and the third cell identifier is a cell identifier selected by the UE from the suggestion identifier list according to a preset reselection rule;

and sending the update refusing notice to the UE based on the context of the UE and the third cell identification, and returning to the step of receiving the second notification area update request sent by the UE.

and when the cell corresponding to the first cell identification does not allow the access of the UE currently, determining to reject the update notification to the UE.

Optionally, the method further comprises:

and when the UE is in an inactive state and data packet transmission is currently performed between the UE and the UE, sending a designated signaling to the UE, wherein the designated signaling carries a fourth cell identifier of a currently performed notification area, and the designated signaling is used for indicating the UE to update the notification area to a cell corresponding to the fourth cell identifier.

Fig. 3 is a flowchart illustrating a notification area update method according to an exemplary embodiment, and as shown in fig. 3, the method includes the following steps.

In step 301, when the UE is in an inactive state, a first cell identifier currently performing notification area update is determined based on a stored cell identifier list, where the cell identifier list stores a plurality of cell identifiers and current signal strength of a cell corresponding to each cell identifier.

The operation of determining, by the UE, the first cell identifier currently performing the notification area update based on the stored cell identifier list may include the following two ways.

In the first mode, when the UE detects a second cell identifier and the second cell identifier is different from the area identifier of the notification area where the UE is currently located, it is determined whether the second cell identifier exists in the cell identifier list; when the second cell identifier exists in the cell identifier list, selecting the cell identifier with the maximum signal intensity from the cell identifier list; and determining the selected cell identifier as the first cell identifier for currently updating the notification area.

It should be noted that the cells involved in the embodiments of the present disclosure are obtained by dividing the coverage area of the base station network. A base station may comprise one or several cells, each cell being assigned an identity which uniquely identifies the corresponding cell.

In addition, the cell identifier list is obtained by the UE from the base station, that is, the UE may receive the cell identifier list broadcasted by the base station in the current cell, where the cell identifiers stored in the cell identifier list are identifiers of all cells under the base station; or, the UE receives a cell identifier list configured by the base station for the UE, where the cell identifiers stored in the cell identifier list are identifiers of cells selected by the base station from all the cells.

It should be noted that, when the base station configures the cell identifier list for the UE, the base station may configure the same cell identifier list for each UE in its coverage area, or may configure different cell identifier lists, and when paging a UE, the base station may configure a cell identifier list for the UE and send the cell identifier list to the UE.

Further, when the second cell identifier does not exist in the cell identifier list, the UE may determine whether the signal strength of the cell corresponding to the second cell identifier is greater than or equal to a preset strength threshold, and determine whether the signal strength of the cell corresponding to the second cell identifier is greater than the signal strength of the cell corresponding to each cell identifier in the cell identifier list. And when the signal intensity of the cell corresponding to the second cell identifier is greater than or equal to a preset intensity threshold value and the signal intensity of the cell corresponding to the second cell identifier is greater than the signal intensity of the cell corresponding to each cell identifier in the cell identifier list, determining the second cell identifier as the first cell identifier currently carrying out notification area update.

It should be noted that the preset intensity threshold may be set in advance, for example, the preset intensity threshold may be 60db (decibel), 70db, or the like.

In addition, when the signal strength of the cell corresponding to the second cell identifier is smaller than the preset strength threshold, or the signal strength of the cell corresponding to the second cell identifier is smaller than the signal strength of the cell corresponding to any cell identifier in the cell identifier list, the UE may abandon the update operation of the notification area, delete the context, and switch from the inactive state to the idle state.

In a second mode, when the update time of the periodic update notification area configured by the UE arrives, the cell identifier with the maximum signal strength is selected from the cell identifier list; and determining the selected cell identifier as the first cell identifier for currently updating the notification area.

It should be noted that the base station may configure an update period of the notification area for the UE, and the update period may be 1 day, 2 days, and so on.

It should be noted that when the UE selects the cell identifier with the highest signal strength and the area identifier of the notification area currently located, the UE will not initiate the notification area update operation.

In step 302, the UE sends a first notification area update request to the base station, where the first notification area update request carries a first cell identifier and a base station identifier of a base station accessed when performing notification area update last time.

It should be noted that the base station identifier is used to uniquely identify the base station accessed by the UE when the UE performs the notification area update last time, and the base station identifier may be an IP (internet protocol), an MAC (media access control), and the like of the base station.

In addition, in order to facilitate that the subsequent UE can continue the update operation of the notification area, the first notification area update request may not only carry the first cell identifier and the base station identifier of the base station accessed when the notification area is updated last time, but also carry an identifier detection list in the first notification area update request, where the identifier detection list includes the cell identifiers of all cells detected by the UE and corresponding signal strengths, and in actual application, the identifier detection list may also include the cell identifiers of some cells detected by the UE and corresponding signal strengths.

It should be noted that, in order to ensure that the UE can smoothly send the first notification area update request to the base station and avoid the influence of other data, the UE may suspend signaling bearer and data bearer when sending the first notification area update request.

In step 303, the base station receives a first notification area update request sent by the UE.

In step 304, when the base station identifier is different from the identifier of the base station, the base station acquires the context of the UE from the base station corresponding to the base station identifier.

Since the context of the UE includes information such as network capabilities, authentication information, negotiated security algorithm, generated keys, created connection information, IP of the UE, etc. The information is an important basis that the base station can process the UE, and when the base station cannot know the context of the UE, the base station cannot know information such as a PGW (PDN GateWay) connected to the UE and a bearer created by the UE, so that the base station cannot process a request sent by the UE. Therefore, in order to ensure that the base station can process the notification area update request sent by the UE, the base station needs to acquire the context of the UE from the base station corresponding to the base station identifier.

After obtaining the context of the UE, the base station may determine whether the number of currently accessed UEs of the cell corresponding to the first cell identifier is greater than or equal to a preset number, and when the number of currently accessed UEs of the cell corresponding to the first cell identifier is greater than or equal to the preset number, determine to send an update rejection notification to the UE; or, when the cell corresponding to the first cell identifier does not currently allow the access of the UE, determining to send a reject update notification to the UE.

It should be noted that the preset number may be set in advance, for example, the preset number may be 100, 200, and so on.

In addition, when the cell corresponding to the first cell identifier currently allows the UE to access and the number of currently accessed UEs in the cell corresponding to the first cell identifier is less than the preset number, it is determined to send the update rejection notification to the UE and perform the operation of sending the update permission notification in step 305 described below. The permission notification update is used to instruct the UE to update the notification area based on the first cell identifier, and the permission notification update may carry information such as a new UE status identifier and a new security key assigned to the UE.

In a possible implementation manner, after obtaining the context of the UE from the base station corresponding to the base station identifier, the base station may send an update rejection notification to the UE based on the context of the UE and the first cell identifier, where the update rejection notification carries an update rejection reason and a proposed identifier list, and the proposed identifier list stores a cell identifier that proposes the UE to perform notification area update; the UE receives the update rejection notice sent by the base station, selects a cell identifier from the suggested identifier list according to a preset reselection rule, and determines the selected cell identifier as a third cell identifier; sending a second notification area updating request to the base station, wherein the second notification area updating request carries a third cell identifier and a base station identifier of the base station accessed when the notification area is updated last time; the base station receives a second notification area updating request sent by the UE; when the base station identification is different from the identification of the base station, acquiring the context of the UE from the base station corresponding to the base station identification; sending the reject update notification to the UE based on the context of the UE and the third cell identity. And when the UE receives the update rejection notification sent by the base station again, returning to execute the step of selecting a cell identifier from the suggested identifier list according to the preset reselection rule and determining the selected cell identifier as a third cell identifier. And the base station returns to execute the step of receiving the second notification area updating request sent by the UE.

Since the context of the UE may include information such as the IP of the UE, the base station may send the update rejection notification to the UE based on the IP of the UE carried in the context of the UE.

It should be noted that the preset reselection rule is used to select a cell identifier from the suggested identifier list, and the preset reselection rule may be set in advance, for example, the preset reselection rule may be to select a cell identifier according to a descending order of signal strength, or to select a cell identifier according to an ascending order of cell identifiers in the suggested identifier list, or the like.

It should be noted that, when the UE sends the first notification area update request to the base station, the first notification area update request may further carry an identifier detection list, and therefore, the proposed identifier list sent by the base station to the UE may include all cell identifiers and corresponding signal strengths acquired by the base station from the identifier detection list, or include part of cell identifiers and corresponding signal strengths acquired from the identifier detection list.

In another possible implementation manner, when the base station cannot acquire the context of the UE from the base station corresponding to the base station identifier, the base station may directly send a notification of rejecting updating to the UE.

In another possible implementation manner, when the base station obtains not only the context of the UE from the base station corresponding to the base station identifier, but also obtains the history cell list where the UE resides, the base station may determine the history movement track of the UE according to the cell identifier in the history cell list where the UE resides, and predict a cell where the UE moves next time according to the history movement track of the UE, and when the cell identifier of the cell where the base station predicts the next time and the area identifier of the notification area where the base station is currently located are different, send a notification of rejecting update to the UE.

In another possible implementation manner, when the update rejection notification sent by the base station to the UE carries the update rejection reason but does not carry the suggested identity list, the UE may abandon the update of the notification area this time and delete the context of the UE when receiving the update rejection notification, and switch from the inactive state to the idle state.

Moreover, in order to avoid resource waste caused by the UE repeatedly sending the same notification area update request to the base station, after the UE sends the second notification area update request to the base station, the UE may also count the number of times of sending the second notification area update request; and when the sending times are larger than or equal to a preset time threshold value, deleting the context of the UE and switching from the inactive state to the idle state.

It should be noted that the preset number threshold may be set in advance, for example, the preset number threshold may be 5 times, 6 times, and so on.

In step 305, the base station sends an update allowed notification to the UE based on the context of the UE and the first cell identity.

Wherein, since the context of the UE may include connection information created by the UE, an IP of the UE, and other information, the base station may send an update permission notification to the UE based on the IP of the UE carried in the context.

In step 306, the UE receives the update permission notification sent by the base station, and updates the notification area to the cell corresponding to the first cell identifier.

After the UE updates the notification area to the cell corresponding to the first cell identifier, it may also send an update completion notification to the base station, and when the base station receives the update completion notification sent by the UE, it determines that the UE notifies that the area update is completed. It should be noted that, when the UE receives the update permission notification carrying the new security key, the UE may send an update completion notification to the base station using the new security key, so as to ensure security of communication between the UE and the base station.

In addition, when the UE is a periodically updated notification area, after the UE updates the notification area to the cell corresponding to the first cell identifier, the UE may restart a timer for periodically updating the notification area.

Further, after the UE updates the notification area to the cell corresponding to the first cell identifier, when it is detected that the notification area is not updated within a specified duration after the notification area is updated, the context of the UE is deleted, and the UE is switched from the inactive state to the idle state. The specified time period may be set in advance, for example, the specified time period may be 1 day, 2 days, or the like.

In addition, since the UE may waste power consumption of the UE even if the UE is in the inactive state for a long time, the UE may delete the context of the UE and switch from the inactive state to the idle state when it is detected that the notification area is not updated within a specified time period after the notification area is updated.

It should be noted that the UE may update the notification area not only when determining the identity of the first cell, but also when receiving the specific signaling. That is, when the UE is in the inactive state and data packets are currently transmitted between the base station and the UE, the base station may send a specific signaling to the UE, where the specific signaling carries a fourth cell identifier of a currently performed notification area, and the specific signaling is used to instruct the UE to update the notification area to a cell corresponding to the fourth cell identifier. And the UE receives the designated signaling and updates the notification area to the cell corresponding to the fourth cell identifier.

In the embodiment of the present disclosure, when the UE is in the inactive state, data packets transmitted between the UE and the base station are all small data packets, that is, data packets with a transmission size smaller than a preset size. The preset size may be set in advance, for example, the preset size may be 5MB (mega), 10MB, or the like.

In the embodiment of the present disclosure, the UE may determine the first cell identifier through the stored cell identifier list, and update the notification area according to the first cell identifier, so that when the notification area where the UE is located in the inactive state is changed, the notification area can be updated. In addition, when the base station rejects the UE to update through the first cell identifier, if the update rejection notification carries the proposed identifier list, the UE can also update the notification area according to the cell identifier in the proposed identifier list, thereby improving the reliability of updating the notification area. Furthermore, when the UE detects the second cell identifier in the inactive state, if the signal strength of the corresponding cell is smaller than the preset strength threshold, or the signal strength of the cell corresponding to the second cell identifier is smaller than the signal strength of the cell corresponding to any cell identifier in the cell identifier list, the UE may abandon the update operation of the notification area, thereby avoiding unnecessary update of the notification area, and improving the efficiency of updating the notification area.
