The calculation method may directly query the system frame number (SFN) or the subframe number corresponding to the absolute time according to the absolute time, where the system frame number is not synchronized because the primary base station and the secondary base station are not synchronized. Or the subframe number is the system frame number or subframe number of the primary base station.

603. The primary base station sends the system message change indication and the system frame number that the system message is valid to

UE.

For example, the primary base station may also send a system message change indication and a subframe number in which the system message is valid to the UE.

The specific implementation may be: The primary base station may send the system message change indication and the system frame number or the subframe number in which the system message is valid to the UE by using high layer signaling (for example, RRC dedicated signaling).

604. The UE receives the system message according to the received system message modification indication and the system frame number that the system message takes effect, and receives the system message under the specified system frame number and the corresponding secondary base station, and the system message is valid.

For example, the UE may also receive the system message modification indication sent by the primary base station and the subframe number in effect of the system message, receive the system message under the specified subframe number and the corresponding secondary base station, and validate the system message.

In the embodiment of the present invention, when the primary base station and the secondary base station are not synchronized, the primary base station determines, according to the effective time of the changed system message sent by the secondary base station, the system frame number or the child whose effective time of the changed system message is in the primary base station. a frame number, and the system frame number or the subframe number of the determined system message effective time, and the system message change indication sent by the secondary base station are sent to the user equipment, so that the user equipment is configured according to the received system frame number. Or the subframe number receives the system message under the corresponding secondary base station, and the system message is validated; the existing 3GPP Release-10 version does not support the inter-base station cell aggregation, and after the secondary base station system message changes, the user equipment UE Unable to get The system message after the change of the secondary base station is taken, so that the UE cannot access the network or cannot work normally, affecting data transmission, and increasing the risk of data loss.

Further, in this embodiment, the primary base station sends only the change indication of the secondary base station system message to the user equipment, instead of the system message changed by the secondary base station, and therefore, the air interface resource occupancy rate can be further reduced.

FIG. 7 is a schematic signaling diagram of a system message processing method according to another embodiment of the present invention; assuming that the X2 interface and the air interface delay are relatively small, the primary base station may immediately send the changed system message sent by the secondary base station to the UE, and the UE receives The system message is valid immediately after the changed system message, and the process of the system message processing method specifically includes:

701. The secondary base station sends the changed system message to the primary base station.

When the secondary base station changes the system message, the changed system message can be sent to the primary base station through the X2 interface. The X2 interface can use an existing process, such as a base station configuration update (English: eNB Configuration Update) process, or the Χ2 interface can use a new process, such as a system change notification process.

To further reduce data loss, the secondary base station can deactivate the secondary base station before the system message changes.

702. The primary base station sends the changed system message sent by the secondary base station to the UE.

After receiving the changed system message sent by the secondary base station, the primary base station immediately sends the changed system message to the UE. Specifically, it can be sent through RRC dedicated signaling, as included in the RRC Connection Reconfiguration message.

703. After receiving the changed system message, the UE immediately implements the changed system message. 704. The UE sends a success response message to the primary base station.

After the UE successfully validates the changed system message, the UE may send a success response message to the primary base station, and may be sent by using RRC dedicated signaling, for example, in the RRC Connection Reconfiguration Complete message. 705. The primary base station sends a system message modification success message to the secondary base station.

After receiving the success response message of the system message sent by the UE, the primary base station may send a system message modification success message to the secondary base station. After receiving the system message modification success message, the secondary base station may be reactivated.

Since the X2 interface and the air interface delay of this embodiment are relatively small, the delay between the deactivation and reactivation of the secondary base station is almost negligible.

In the embodiment of the present invention, when the X2 interface and the air interface delay between the primary base station and the secondary base station are almost negligible, the primary base station may immediately send the changed system message sent by the secondary base station to the UE, and the UE receives the The system message is valid immediately after the changed system message; the existing 3GPP Release-10 version does not support inter-base station cell aggregation. After the secondary base station system message changes, the user equipment UE cannot obtain the changed base station system. The message causes the UE to be unable to access the network or work normally, affecting data transmission and increasing the risk of data loss.

In this embodiment, the secondary base station may deactivate the secondary base station before the system message is changed. After receiving the system message modification success message, the secondary base station may be reactivated to further reduce data loss.

FIG. 8 is a schematic diagram of signaling of a system message processing method according to another embodiment of the present invention; as shown in FIG. 8, 4 is configured to send a system message to a UE by using a paging message (English: paging), respectively, because When the UE receives system messages simultaneously under two base stations, it needs to listen for paging.

It should be noted that, in an actual application, when the system message changes, the primary base station or the secondary base station sends a paging message to notify the user equipment to receive the changed system message and the effective time of the system message, where the system message includes a special system. News, for example, the Earthquake and Tsunami Warning System (ETWS) message and the Commercial Mobile Alert Service (CMAS) message, due to the timeliness of this special system message If the special system message is included in the paging message sent by the primary or secondary base station, the effective time of the special system message may not be carried, that is, the effective time of the special system message is effective immediately.

According to a paging policy preset by the cell aggregation between the base stations, for example, the preset paging policy is that the UE receives the ETWS changed system message and the effective time of the system message only by the primary base station, and when the UE receives the ETWS sent by the secondary base station. When the changed system message and the effective time of the system message change the indicated paging message, the UE may ignore the system message change indication ETWS message. Or the system message changes the ETWS message without receiving the changed system message and the effective time of the system message. That is, when the primary base station or the secondary base station is to send the changed system message and the effective time ETWS message of the system message, the UE can only obtain the changed system message and system of the primary Kiev base station through the paging message sent by the primary base station. The effective time of the message is ETWS message.

For example, the preset paging policy is a first-come-first-served principle. That is, when the UE receives the paging message sent by the secondary base station and includes the changed system message and the effective time of the system message, it is determined whether it is already The effective time of receiving the changed system message and the system message under the primary base station, if not, receiving the changed system message and the effective time of the system message under the secondary base station.

In the embodiment shown in FIG. 4 to FIG. 8 , the UE obtains the secondary base station in the paging message sent by the primary base station or the secondary base station according to the preset paging policy by using the paging message sent by the secondary base station and the primary base station respectively. The changed system message and the effective time of the system message; the existing 3GPP Release-10 version does not support inter-base station cell aggregation. After the secondary base station system message changes, the user equipment UE cannot obtain the changed secondary base station. System messages, which result in the UE not being able to access the network or not working properly, affecting data transmission and increasing the risk of data loss.

It should be noted that when the UE obtains the system message to be changed and the effective time of the system message by monitoring the paging message, the UE may waste air interface resources. Therefore, in the normal case, this method is not used. In special cases, for example, the Earthquake and Tsunami Warning System (ETWS) message and the Commercial Mobile Alert Service (CMAS) message, due to the aging of this special system message. Urgency, the primary base station or the secondary base station needs to send a special system message to the user equipment in the manner of paging special system messages.

It should be noted that, in the foregoing embodiments shown in FIG. 4 to FIG. 8 , in a practical application, the secondary base station includes multiple cells, and when one or more of the secondary base stations are to change system messages, the secondary base station may The system identifier is carried in the system message to be changed sent to the primary base station, and when the system message and the system message are to be changed, the user equipment may apply the change at the effective time by using the cell corresponding to the cell identifier. System message.
