Here, the second type of system message is a system message determined by the terminal that the terminal may be interested in. The terminal may actively notify the source base station of the second type of system message before the handover occurs, or may notify the source base station of the second type of system message according to the request of the source base station.

Here, the third type of system message is a system message determined by the source base station that the terminal may be interested in and / or useful to the terminal. For example, the source base station may determine that the terminal may be interested in the second type of system message notified by the terminal. System messages, and / or, the source base station itself determines system messages that are useful to the terminal. Optionally, the system messages of the third type may include all or part of the system messages of the system messages of the second type, and may further include system messages other than the system messages of the second type. During the handover process, the source base station may notify the target base station of the third type of system message through a handover request message and / or a handover preparation command.

Here, the first type of system message is a system message determined by the target base station that the terminal may be interested in or useful to the terminal. For example, the target base station may determine a system that the terminal may be interested in according to the third type of system message notified by the source base station. Messages, and / or, the target base station itself determines system messages that are useful to the terminal. Optionally, the first type of system messages may include all or part of the third type of system messages, and may also include other system messages than the third type of system messages. During the handover process, the target base station may use one or more of a handover command, a message of a random access process 2, a message of a random access process 4, and a Radio Resource Control (RRC) connection reconfiguration message. The terminal is notified of the first type of system message, or after the terminal switches to the target base station, the terminal may be notified of the first type of system message.

Next, the method for sending and receiving system messages of some embodiments of the present disclosure will be introduced from each device side, respectively.

Referring to FIG. 2, some embodiments of the present disclosure provide a method for sending a system message, which is applied to a source base station for terminal handover. As shown in FIG. 2, the method includes:

Step 11: The source base station sends the first indication information of the third type of system message to the target base station, wherein the first indication information includes at least the type of the third type of system message.

Here, the third type of system message is a system message that the terminal may be interested in and / or useful to the terminal. The first indication information may further include one or more of the following information: a version number, content, scheduling window length, scheduling period, modification period, whether it is being broadcast, and a system message of each system (Per area) ) A system message or a per-cell system message, and when the system message is a Perarea system message, an area ID corresponding to the system message.

Specifically, as an implementation manner, the third type of system message is usually a system message that the terminal reports to the source base station of interest, and may include, for example, a Master Information Block (MIB) and a system information block. System messages other than 1 (System Information Block 1, SIB1), such as SIB2, SIB12, or other system messages.

Here, the first indication information may generally include the type of the first type of system message, such as the number of the SIB message, and may also include the version number of the first type of system message, specific content of the system message, the length of the scheduling window, Period, modification period, whether it is being broadcast, the system message is a per-area system message or a per-cell system message, and when the system message is a per-area system message, the area corresponding to the system message Identification (area ID).

Here, the source base station may send the first indication information to the target base station by using a handover request message and / or a handover preparation command.

Send related system messages quickly during the process or after the handover is completed, which can help the terminal obtain system messages of the desired target cell more quickly. In addition, some embodiments of the present disclosure can use signaling in the handover process in related technologies. Messages send related system messages, which can save signaling overhead for system messages.

Before sending the first indication information in step 11, the source base station may determine the system message of interest to the terminal in the following manner: For example, the source base station may receive the second type of terminal interest reported by the terminal. The second indication information of the system message, and then according to the second indication information, determine a system message of interest to the terminal. Here, the second indication information may be sent by the terminal to the source base station based on the measurement report when the measurement report meets a predetermined condition (for example, the signal quality of the current serving cell is lower than a predetermined threshold), or may be the terminal according to the source base station. For example, the source base station sends to the terminal a request message for requesting to report a system message that the terminal is interested in, and then the source base station receives a second base station that is sent by the terminal according to the request message and indicates that the terminal is interested. The second indication information of the system-like message. Specifically, as an implementation manner, the source base station may send the request message to the terminal when it is determined that the terminal needs to be handed over. Of course, the source base station may also send the above request message at other timings, such as when the terminal enters the connected state, etc. This article does not specifically limit this.

Before sending the first indication information in step 11, the source base station may determine system messages useful to the terminal by itself, for example, according to the device type of the terminal, the service type of the terminal, and the service of the terminal Information such as history records determines system information useful to the terminal, which is not specifically limited in this article.

It should be noted that in the above embodiments, the system information in the first indication information or the second indication information may be based on the granularity per SIB type (Per SIB type), or per scheduling information (Per schedule) Granularity. As an optional implementation manner, the first indication information is based on a granularity per SIB type. Of course, when the target base station has obtained the SIB type included in the granularity of each scheduling information (Per schedule information) on the source base station side, the first indication information may also be the granularity of each scheduling information (Per schedule). The target base station may determine the type of the specific SIB message indicated by the first indication information based on the granularity of each scheduling information (Per schedule information) on the source base station side.

The method for sending system messages of some embodiments of the present disclosure has been described above from the source base station side, and will be further described below from the target base station side.

Here, during the terminal handover process, the target base station may receive the first indication information of the third type of system message sent by the source base station, where the first indication information includes at least the type of the third type of system message.

Here, the third type of system message is a system message that the terminal may be interested in and / or useful to the terminal. The system messages of interest to the terminal may generally include system messages other than MIB and SIB1, such as SIB2, SIB12, or other system messages.

Here, the target base station may receive the first indication information sent by the source base station through a handover request message and / or a handover preparation command. According to different types of handover, the first indication information may be sent through an interface between the source base station and the target base station, or may be sent by the source base station to the core network element, and forwarded to the target base station via the core network element. Some embodiments do not specifically limit this.

Sending, which can help the terminal obtain system messages of the desired target cell more quickly. In addition, some embodiments of the present disclosure can use the signaling messages in the handover process in the related art to send related system messages, which can save system messages. Signaling overhead.

Therefore, after the above step 21, the above method may further include:

Step 22: The target base station sends a first type of system message to the terminal.

Here, the first type of system message may include all or part of the third type of system message.

Specifically, as a first implementation manner of step 22, the target base station may use a handover command, message 2 of the random access process (ie, MSG2, random access response (RAR) message), and random access process. One or more of message 4 (ie, MSG4, Contention Resolution message) and Radio Resource Control (RRC) connection reconfiguration message, sending scheduling information of the first type of system message. Further, after the target base station sends the scheduling information of the first type of system message, the target base station sends the first type of system message according to the scheduling information, for example, at a scheduling period and a scheduling window corresponding to the first type of system message. send.

As a second implementation manner of step 22, the target base station may use the handover command, message 2 of the random access process (ie, MSG2, random access response (RAR) message), and message 4 of the random access process ( That is, one or more of MSG4, Contention Resolution message, and Radio Resource Control (RRC) connection reconfiguration message, and the system message content of the first type of system message is sent.

Of course, the above two implementation manners can also be used in combination, that is, the target base station sends one or more of a handover command, a message of a random access process 2, a message of a random access process 4, and an RRC connection reconfiguration message. Describe the scheduling information and system message content of the first type of system messages;

As a third implementation manner of step 22, after the terminal is handed over to the target base station, the target base station may actively send scheduling information and / or system message content of the first type of system message. Further, after sending the scheduling information of the first type of system message, the target base station sends the first type of system message according to the scheduling information.

Similarly, the scheduling information of the first type of system message may be based on the granularity per SIB type (Per SIB type) or the granularity per scheduling information (Per schedule).

It should be noted that in some embodiments of the present disclosure, the target base station may send part or all of the system messages in the first type system in the above step 22, which is not specifically limited in some embodiments of the present disclosure.

Through the above steps, the target base station of some embodiments of the present disclosure can send system messages to the terminal of the target cell that the terminal is interested in as early as possible during the handover process, and some embodiments of the present disclosure can make use of Signaling messages during the handover process send related system messages, which can save the signaling overhead of system messages.

In some embodiments of the present disclosure, the first indication information may generally include a type of a third type of system message, such as a number of an SIB message, and may further include at least one of the following information: a version number of the system message, and a system message. The specific content, the length of the scheduling window, the scheduling period, the modification period, whether it is being broadcast, the system message is a per-area system message or a per-cell system message, and the system message is a per-area system When the message is sent, the area ID corresponding to the system message. Therefore, in step 22 above, the target base station sending the scheduling information of the first type of system message may specifically include: After receiving the first indication information, the target base station may determine the first type of system message based on the first indication information. Whether the respective system messages are the same at the source base station and the target base station side; and, the scheduling information for sending the first type of system messages and the system information for indicating that the first type of system messages are at the source base station and the target base station side Whether the same prompt message.

Specifically, the target base station may indicate, by using a bitmap or a predefined field, whether each system message in the first type of system message is the same at the source base station and the target base station. For example, a 4-bit bitmap "1001" indicates that the first and fourth system messages in the first type of system message sent in step 22 are consistent with the source base station, and the terminal can continue to use the system of the source base station Messages are not updated, and the second and third system messages need to be updated.

Furthermore, when sending the scheduling information of the first type of system message, it may carry at least one of the following information: the system message type, version number, content, scheduling window length, scheduling period, modification period, whether it is broadcasting, The system message is a per-area system message or a per-cell system message, and when the system message is a per-area system message, information such as an area ID corresponding to the system message.

Referring to FIG. 4, some embodiments of the present disclosure provide a method for receiving a system message, which is applied to a source base station in a handover process. As shown in FIG. 4, the method includes:

Step 31: The terminal receives the first type of system message sent by the target base station.

Here, specifically, the terminal may receive the first type of system message that the terminal is interested in and sent by the target base station during the handover process or when it enters the connected state after the handover is completed. The first type of system messages are system messages that the terminal may be interested in and / or useful to the terminal.

Through the above steps, the terminal can quickly obtain the system messages of the target base station (cell) that it is interested in or useful for during the handover process or after the handover is completed, thereby saving the time overhead of the terminal obtaining the relevant system messages.

Further, as an implementation manner, in the above step 31, the terminal may use one or more of a handover command, a message of a random access procedure 2, a message of a random access procedure 4, and an RRC connection reconfiguration message. And receiving the first-type system message and / or system message content sent by the target base station, and after receiving the scheduling information of the first-type system message, the terminal may receive the first-type system message according to the scheduling information. The first type of system message.

As another implementation manner, in step 31 above, after the terminal switches to the target base station, the terminal receives scheduling information and / or system message content of the first type of system message actively sent by the target base station. After receiving the scheduling information of the first-type system message, the terminal receives the first-type system message according to the scheduling information.

Here, the target base station may send all or part of the system messages in the first type of system message.

Here, the scheduling information of the first type of system messages is based on the granularity per SIB type (Per SIB type) or the granularity per scheduling information (Per schedule).

Here, the first type of system message may include the type and content of the first type of system message, and may further include at least one of the following information: the type, version number, content, The length of the scheduling window, the scheduling period, the modification period, whether it is being broadcast, the system message is a per-area system message or a per-cell system message, and when the system message is a per-area system message, the system Area ID corresponding to the message.

In some embodiments of the present disclosure, the terminal may update the system message according to the received first type of system message. Optionally, the terminal may update the source base station in the first type of system message according to the indication information indicating whether each system message in the first type of system message is the same at the source base station and the target base station. The system message is different from the target base station. For the same system message, it is not necessary to update.

Further, when receiving the scheduling information of the first type of system message, the terminal may also receive the system information sent by the target base station to indicate that each system message in the first type of system message is at the source base station and the target base station. Whether the two sides are the same prompt information; further, when receiving the first type of system message, according to the prompt information and / or the scheduling information of the first type of system message, receiving the source in the first type of system message Different system messages on the base station and target base stations. For example, according to the prompt information and the scheduling information of the first type of system message, a system message different from the source base station and the target base station side in the first type of system message is received.

Furthermore, the terminal of some embodiments of the present disclosure may actively or at the request of a currently serving base station (which may be a source base station or a target base station) send the indication information of the second type of system message in which it is interested. For example, before step 31 described above, the terminal may send indication information to the current serving base station to indicate a second type of system message that the terminal is interested in. Specifically, the terminal may send the indication information after receiving a request message from the serving base station requesting to report a system message of interest to the terminal; and / or, the terminal actively sends the indication information, For example, the terminal may send the indication information when a predetermined condition is satisfied according to a measurement report. The indication information or the system message in the request message is based on the granularity per SIB type (Per SIB type) or the granularity per scheduling information (Per schedule).

In this way, the serving base station (source base station) can obtain the system messages that the terminal is interested in, and then send the indication information of the above system message to the target base station during the handover process, so as to speed up the sending of related system messages during the handover process and save time And signaling overhead.
