Technical Field

The present invention relates to the field of mobile communications technologies, and in particular, to a method and a device for sending and receiving a system message.

Background

In the aspect of sending system messages, the 5G introduces a system message sending mode according to needs, that is, some system message base stations (gbb, radio access network RAN node of the 5G new air interface system) may not broadcast and send the system message, and the system message is sent to the UE in a broadcast or unicast mode after the terminal (UE) actively requests the gbb.

In the LTE system, since system messages are usually broadcast, a base station (eNB of the LTE system) does not know which system messages are interested by the UE, so that the target base station only sends information required for accessing the target cell to the UE in the handover command, and other system messages are acquired after the UE is synchronized with the target base station, which requires introducing additional delay (the UE waits for a new system message in the target cell) or signaling (the base station sends the system message to the UE through dedicated signaling).

The new air interface (NR) system introduces a system message sending mode of sending on demand, and for a UE requesting some system messages, the gNB knows part or all of the system messages in which the UE is interested, so that the information can be used to help the UE to acquire the system messages of the required target cell more quickly and with less signaling.

Referring to fig. 1, an application scenario diagram of a method for sending/receiving a system message according to an embodiment of the present invention is shown. In fig. 1, a terminal is handed over from a source base station to a target base station. The terminal may notify a system message (which may be referred to as a second type system message) that may be of interest to the source base station, the source base station may notify a system message (which may be referred to as a third type system message) that may be of interest to the terminal or that is useful to the terminal to the target base station, and the target base station may actively notify the system message (which may be referred to as a first type system message) that may be of interest to the terminal or that is useful to the terminal, so that the terminal may be helped to acquire the system message of the target base station (target cell) more quickly.

Here, the second type of system message is a system message that the terminal determines 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 a request of the source base station.

Here, the third type of system message is a system message that is determined by the source base station to be likely to be of interest to the terminal and/or to be useful to the terminal, for example, the source base station may determine a system message that is likely to be of interest to the terminal according to the second type of system message notified by the terminal, and/or the source base station may determine a system message that is useful to the terminal by itself. Preferably, the third type of system message may include all or part of the system messages in the second type of system messages, and may also include other system messages besides the second system messages. The source base station may notify the third type system message to the target base station through a handover request message and/or a handover preparation command during a handover process.

Here, the first type of system message is a system message that is determined by the target base station to be possibly interesting or useful for the terminal, for example, the target base station may determine a system message that is possibly interesting for the terminal according to the third type of system message notified by the source base station, and/or the target base station may determine a system message that is useful for the terminal by itself. Preferably, the first type of system message may include all or part of the system messages in the third type of system message, and may further include other system messages besides the third system message. The target base station may notify the terminal of the first type system message through one or more of a handover command, a message 2 of a random access procedure, a message 4 of the random access procedure, and an RRC connection reconfiguration message in a handover procedure, or may actively notify the terminal of the first type system message after the terminal is handed over to the target base station.

Next, the method for transmitting and receiving the system message according to the embodiment of the present invention will be described from each device side.

Referring to fig. 2, an embodiment of the present invention provides a method for sending a system message, which is applied to a source base station for terminal handover, and as shown in fig. 2, the method includes:

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

Here, the third type of system message is a system message that may be of interest to and/or useful for the terminal. The first indication information may further include one or more of the following information: the system message comprises a version number, content, a scheduling window length, a scheduling period, a modification period, whether the system message is broadcast, the system message is Per-area Per-cell Per-area system message, and when the system message is Per-area system message, an area ID corresponding to the system message is identified.

Specifically, as an implementation manner, the third type of system message is generally a system message of interest that is reported by the terminal to the source base station, and may include system messages other than the MIB and the SIB1, such as SIB2, SIB12, or other system messages.

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

Here, the source base station may send the first indication information to the target base station through a handover request message and/or a handover preparation command. According to different handover types, the first indication information may be sent through an interface between the source base station and the target base station, or may be sent to the core network element by the source base station, and forwarded to the target base station through the core network element.

Through the above steps, the source base station can send the system message interested by the terminal and/or the indication information of the system message useful for the terminal to the target base station in the switching process, so that the target base station can quickly send the related system message in the switching process or after the switching is completed, and the terminal can be helped to quickly acquire the system message of the required target cell.

Before sending the first indication information in step 11, the source base station may determine the system message in which the terminal is interested in the following manner: for example, the source base station may receive second indication information of a second type of system message that is reported by the terminal and is interested by the terminal, and then determine the system message that is interested by the terminal according to the second indication information. Here, the second indication information may be sent by the terminal to the source base station when the measurement report satisfies a predetermined condition (for example, the signal quality of the current serving cell is inferior to a predetermined threshold) based on the measurement report, or may be sent by the terminal according to a request of the source base station, for example, the source base station sends a request message for requesting reporting a system message in which the terminal is interested to the terminal, and then the source base station receives the second indication information sent by the terminal according to the request message for indicating a second type of system message in which the terminal is interested. Specifically, as an implementation manner, the source base station may send the request message to the terminal when determining that the terminal needs to perform handover. Of course, the source base station may also send the request message at other occasions, such as when the terminal enters a connected state, and the like, which is not specifically limited herein.

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

It should be noted that, in the above embodiment, the system message in the first indication information or the second indication information may be based on a granularity Per SIB type (Per SIB type), or a granularity Per scheduling information (Per scheduling info). As a preferred embodiment, the first indication information is based on granularity Per SIB type (Per SIBtype). Of course, when the target base station has obtained the SIB type included in the granularity of each scheduling information (Per scheduling info) on the source base station side, the first indication information may also be the granularity of each scheduling information (Per scheduling info), and the target base station may determine the specific SIB message type indicated by the first indication information based on the granularity of each scheduling information (Per scheduling info) on the source base station side.

The method for sending the system message according to the embodiment of the present invention is described above from the source base station side, and is further described below from the target base station side.

Referring to fig. 3, an embodiment of the present invention provides a method for receiving a system message, which is applied to a target base station for terminal handover, and as shown in fig. 3, the method includes:

step 21, the target base station receives first indication information of a third type system message sent by the source base station, wherein the first indication information at least includes a type of the third type system message.

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

Here, the third type of system message is a system message that may be of interest to and/or useful for 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 transmitted by the source base station through a handover request message and/or a handover preparation command. According to different handover types, the first indication information may be sent through an interface between the source base station and the target base station, or may be sent to the core network element by the source base station, and forwarded to the target base station through the core network element.

Through the above steps, the embodiment of the present invention can receive the first indication information sent by the source base station by the target base station in the handover process, so that the target base station can quickly send the related system message in the handover process or after the handover is completed, thereby helping the terminal to quickly obtain the system message of the required target cell.

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

step 22, the target base station sends the first type 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 send the scheduling information of the first type system message through one or more of a handover command, a message 2 of a random access procedure (i.e., MSG2, a Random Access Response (RAR) message), a message 4 of the random access procedure (i.e., MSG4, a Contention resolution (Contention resolution) message), and a Radio Resource Control (RRC) connection reconfiguration message. Further, after the target base station sends the scheduling information of the first type system message, the target base station sends the first type system message according to the scheduling information, for example, in a scheduling period and a scheduling window corresponding to the first type system message.

As a second implementation manner of step 22, the target base station may send the system message content of the first system message through one or more of a handover command, a message 2 of a random access procedure (i.e., MSG2, Random Access Response (RAR) message), a message 4 of the random access procedure (i.e., MSG4, Contention resolution (Contention resolution) message), and a Radio Resource Control (RRC) connection reconfiguration message.

Of course, the two implementation manners may also be used in combination, that is, the target base station sends the scheduling information and the system message content of the first type of system message through one or more of the handover command, the message 2 of the random access procedure, the message 4 of the random access procedure, and the RRC connection reconfiguration message;

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 the scheduling information and/or the system message content of the first type system message. Further, after sending the scheduling information of the first type system message, the target base station sends the first type system message according to the scheduling information.

Similarly, the scheduling information of the first type system message may be based on the granularity of Per SIB type or the granularity of Per scheduling info Per scheduling information Per SIB scheduling info.

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

Through the steps, the target base station of the embodiment of the invention can send the system message of the target cell interested by the terminal to the terminal as soon as possible in the switching process, and the embodiment of the invention can send the relevant system message by utilizing the signaling message in the existing switching process, thereby saving the signaling overhead of system message sending.

In this embodiment of the present invention, the first indication information may generally include a type of the third type system message, such as a number of an SIB message, and may further include at least one of the following information: the system information comprises a version number of a system message, specific content of the system message, a scheduling window length, a scheduling period, a modification period, whether the system message is being broadcast, whether the system message is a Per-area (Per area) system message or a Per-cell (Per cell) system message, and, when the system message is a Per area system message, an area identifier (area ID) corresponding to the system message. Therefore, in step 22, the step of sending the scheduling information of the first system message by the target base station may specifically include: after receiving the first indication information, the target base station may determine, based on the first indication information, whether each system message in the first type of system messages is the same on the source base station side and the target base station side; and sending scheduling information of the first type of system messages and prompt information used for indicating whether each system message in the first type of system messages is the same on the source base station side and the target base station side.

Specifically, the target base station may indicate, in a bitmap (bitmap) or predefined field manner, whether each system message in the first type of system message is the same on the source base station side and the target base station side. For example, by indicating that the 1 st and 4 th systematic messages in the first type systematic message sent in step 22 are consistent with the source base station through a 4-bit bitmap "1001", the terminal can continue to use the systematic message of the source base station without updating, while the 2 nd and 3rd systematic messages need updating.

Further, when the scheduling information of the first type system message is sent, at least one of the following information may be carried: the system information comprises the type, version number, content, length of a scheduling window, scheduling period, modification period, whether the system information is broadcast, the system information is Perarea system information Per region or Percell system information Per cell, and when the system information is Perarea system information, the information such as area ID corresponding to the system information is identified.

As a preferred mode, when sending the scheduling information of the system message that needs to be updated in the first type of system message, the scheduling information may carry at least one of the following information: the system message type, version number, content, scheduling window length, scheduling period, modification period, whether broadcasting is in progress, the system message is Per area Per cell Per area system message, and when the system message is Per area system message, the area ID and other information of the area identification corresponding to the system message; and when the system message which does not need to be updated in the first type of system message is sent, the type corresponding to the system message can be carried only, so that the load content in the signaling message is reduced.

The following will further give a specific flow at the terminal side in the embodiment of the present invention.

Referring to fig. 4, an embodiment of the present invention provides a method for receiving a system message, which is applied to a source base station in a handover process, and as shown in fig. 4, the method includes:

step 31, the terminal receives the first type system message sent by the target base station.

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

Through the steps, the terminal can quickly acquire the system message of the target base station (cell) which is interested in or useful for the terminal in the switching process or after the switching is finished, so that the time overhead of acquiring the relevant system message by the terminal can be saved.

Further, as an implementation manner, in step 31, the terminal may receive the first-type system message and/or the system message content sent by the target base station through one or more of a handover command, a message 2 of a random access procedure, a message 4 of a random access procedure, and an RRC connection reconfiguration message, 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.

As another implementation manner, in step 31, after the terminal is handed over to the target base station, the terminal receives the scheduling information and/or the system message content of the first type system message actively sent by the target base station. And 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 transmit all or part of the system messages in the first type of system messages.

Here, the scheduling information of the first type system message is based on a granularity of Per SIB type or a granularity of Per scheduling information Per scheduling info.

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

In the embodiment of the invention, the terminal can update the system message according to the received first type of system message. Preferably, the terminal may update the system messages, which are different at the source base station and the target base station side, in the first type of system messages according to the indication information indicating whether the system messages in the first type of system messages are the same at the source base station and the target base station side. And no update may be made for the same system message.

Further, when receiving the scheduling information of the first type of system message, the terminal may further receive a prompt message sent by the target base station to indicate whether each system message in the first type of system message is the same at the source base station and the target base station; and further receiving the system messages which are different at the source base station side and the target base station side in the first type of system messages according to the prompt information and/or the scheduling information of the first type of system messages when the first type of system messages are received. For example, according to the prompt information and the scheduling information of the first-class system message, receiving a system message in the first-class system message, which is different between the source base station and the target base station.

Furthermore, the terminal of the embodiment of the present invention may send the indication information of the second type system message in which it is interested at the request of the active or currently serving base station (which may be the source base station or the target base station). For example, before the step 31, the terminal may send indication information indicating the second type system message in which the terminal is interested to the current serving base station. Specifically, the terminal may send the indication information after receiving a request message sent by the serving base station to request reporting of a system message in which the terminal is interested; and/or the terminal actively sends the indication information, for example, the terminal may send the indication information when a predetermined condition is met according to a measurement report. The indication information or the system message in the request message is based on the granularity of each SIB type Per SIB type or the granularity of each scheduling information Per scheduling info.

Through the method, the serving base station (source base station) can obtain the system message which is interested by the terminal, so that the indication information of the system message is sent to the target base station in the switching process, the sending of the related system message in the switching process is accelerated, and the time and the signaling overhead are saved.

The method for sending and receiving the system message according to the embodiment of the invention is introduced from the source base station, the target base station and the terminal side respectively. The following further provides related equipment for implementing the method.
