Description

Method and device for updating system message

This application claims the priority of the Chinese Patent Application, which is filed on Jun. 22, 2016, the entire disclosure of which is hereby incorporated by reference. .

Technical field

The present invention relates to the field of wireless communication technologies, and in particular, to a method and device for updating a system message.

Background technique

System messages refer to public messages within a cell. In the traditional cellular network, the terminal obtains the complete information in the cell by reading the system message. In order to ensure the smooth reception of the system message, the system message always pre-occupies part of the time-frequency resource.

Taking the LTE (Long Term Evolution) system as an example, the system messages of the LTE system are mainly classified into a MIB (Master Information Block) and a plurality of SIB (System Information Blocks) messages. When a UE (User Equipment, terminal) newly accesses a cell or a broadcast message changes, it will receive a system message (MIB/SIB). The system message includes: MIB, SIB1, and SI (System Information), where the SI message currently includes SIB2 to SIB20, and may continue to expand.

In the future mobile communication system, the manner in which the UE acquires the system message changes, that is, only the basic system message needs to be obtained through broadcast, and the system messages dedicated to other UEs are acquired on an on-demand basis. The so-called on-demand mode acquisition only requests the system message of interest to the network when the UE needs it. The network receives the request of the UE, and sends the related system message to the UE through broadcast or dedicated signaling.

At present, the main problem that the UE uses the on-demand method to obtain system messages is that once the system message is updated, a large number of UEs request the updated system message from the network at the same time, thereby causing network congestion.

As shown in FIG. 1, the system for updating a system message according to an embodiment of the present invention includes: a terminal 10 and a network side device 20.

The terminal 10 is configured to determine, according to the delay configuration information, a time for sending a system message request message after receiving the system message update indication information from the network side device, where at least part of the terminal determines a time for sending the system message request message is different; After the time when the sending system message request message arrives, a system message request message is sent to the network side device.

The network side device 20 is configured to send system message update indication information to the terminal after the system message is updated, and send a system message to the terminal after receiving the system message request message sent by the terminal.

In an implementation, the time of sending the system message request message determined by at least part of the terminal may be different. The time of the system message determined by each terminal is different, or the time of sending the system message request message determined by a part of the terminal is different.

There are many ways for the network side device 20 to send system message update indication information to the terminal, which are listed below:

The method for transmitting the indication information is as follows: The network side device sends the system message update indication information to the terminal by using a paging message;

Correspondingly, the terminal receives system message update indication information from the network side device by using a paging message.

The method of sending the indication information is as follows: the network side device sends the system message update indication information to the terminal by using the basic system message;

Correspondingly, the terminal receives the system message update indication information from the network side device through the basic system message.

The underlying system message is a system message that is transmitted using broadcast.

The method for transmitting the indication information is as follows: The network side device sends the system message update indication information to the terminal by using dedicated signaling;

Correspondingly, the terminal receives system message update indication information from the network side device by using dedicated signaling.

There are a lot of dedicated signaling, such as RRC (Radio Resource Control), MAC (Medium Access Control) signaling, and physical layer signaling.

It should be noted that the foregoing three types of indication information transmission manners are only examples, and any manner in which the system message update indication information can be applied to the embodiments of the present invention.

Optionally, before determining, by the terminal, the time for sending the system message request message according to the delay configuration information, the terminal further needs to determine the delay configuration information.

Among them, there are many ways for the terminal to determine the delay configuration information. Here are a few:

The configuration information determining manner is as follows: the network side device sends the delay configuration information to the terminal by using a paging message;

Correspondingly, the terminal receives the delay configuration information from the network side device by using a paging message.

The configuration information determining manner is as follows: the network side device sends the delay configuration information to the terminal by using a basic system message;

Correspondingly, the terminal receives the delay configuration information from the network side device by using a basic system message.

The configuration information determining manner is as follows: The network side device sends the delay configuration information to the terminal by using dedicated signaling;

Correspondingly, the terminal receives the delay configuration information from the network side device by using dedicated signaling.

There are many dedicated signaling, such as RRC, MAC signaling, physical layer signaling, and so on.

The configuration information determining manner is as follows: The terminal determines the delay configuration information according to a configuration of a standard protocol.

This way is to specify the delay configuration information in the protocol.

Configuration Information Determination Method 5: The terminal uses the length of the system message change period as the delay configuration information.

The configuration information determining mode 6 is that the terminal sets the set duration as the delay configuration information.

In this way, a duration is set, and the duration is used as the delay configuration information. For example, you can set the duration to 0 or other values.

In the implementation, for the configuration information determining manner 6, the foregoing indication information sending manner 3 may be adopted.

It should be noted that the foregoing six types of indication information transmission manners are only examples, and any manner in which the terminal can determine the delay configuration information is applicable to the embodiments of the present invention.

If the delay configuration information of each terminal is the same, that is, the delay configuration information determined by each terminal by using the foregoing configuration information determining manner is the same, the terminal determines the sending system message request message according to the random number obtained by the delay configuration information. time. For example, if the delay configuration information is t, the terminal randomly generates a random number from [0, T]. After the terminal sends the system message request message change indication, the terminal determines the sending system according to the time when the system message update indication is received and the random number. The time when the message requested the message.

Certainly, the terminal may also randomly generate a random number from [0, T] after transmitting the system message request message change indication, and determine a sending system message request message according to the time when the system message update indication is received and the random number. time.

For example, the time when the system message update indication is received may be started as the start time, and the time length is a random number, and the time when the system message request message is sent is determined after the time length is reached.

If the delay configuration information of each terminal is not completely the same, that is, the delay configuration information determined by each terminal by using the foregoing configuration information determining manner is partially the same or different, the terminal may according to receiving the system message update indication. The time and the delay configuration information determine when to send the system message request message.

For example, the time when the system message update indication is received may be started as the start time, and the time length is the value in the delay configuration information, and the time when the system message request message is sent is determined after the time length is reached.

In the implementation, the delay configuration information may also be a specific moment, and the terminal determines the time of sending the system message request message after the arrival of the time, so that it is independent of the time when the system message update indication is received.

In an implementation, the network side device may send the same or different delay configuration information for different terminals.

If the network side device sends the same delay configuration information for different terminals, the optional network side device may adopt the configuration information determining manner 1 and the configuration information determining manner 2;

If the network side device sends different delay configuration information for different terminals, the optional network side device may determine the manner 3 by using the configuration information.

Optionally, the system message update indication information may indicate that the system information is updated, and may also indicate that the updated system information occurs.

If the system message update indication information indicates that the system information is updated, 1 bit (bit) may be used to indicate that the system information is updated, for example, 1 indicates that the system information is updated.

If the system message update indication information indicates that the updated system information is generated, the Nbit may be adopted. For example, the system message update indication information may be the number of the system information, and the corresponding system information is updated as long as the terminal receives the number.

In the implementation, the system message update indication information may include a number of system information, and may also include a number of multiple system information.

If the system message update indication information indicates that the system information is updated, the foregoing instruction information transmission mode 1, the indication information transmission mode 2, the indication information transmission mode 4, the indication information transmission mode 5, and the indication information transmission mode 6 may be adopted.

If the system message update indication information indicates that the updated system information is generated, the foregoing instruction information transmission mode 3 may be adopted.

As shown in FIG. 7, the method for the network side device to send a system message according to the embodiment of the present invention includes:

Step 700: The network side device sends the system message update indication information to the terminal after the system message is updated, so that the terminal requests the network side device to obtain the update after the time of sending the system message request message determined according to the delay configuration information arrives. a subsequent system message, wherein at least some of the terminals determine the time at which the system message request message is sent differently;

Step 701: The network side device sends a system message to the terminal after receiving the system message request message sent by the terminal.

If the system message request message does not carry the system message number to be requested, the network side device sends, to the terminal, a system message that all terminals are interested in; or

Optionally, the system message update indication information includes:

1-bit system message update indication; and/or,

The system message number where the system message update occurred.

The scheme of the present invention will be described in detail below with specific examples.

Embodiment 1: The network carries system message update indication information through a Paging message.

As shown in FIG. 8, the method for updating a paging message system message according to an embodiment of the present invention includes:

Step 1: The network side device determines that the system message has changed.

The network side device (such as the base station) determines that the system message is updated, and further determines the identification information, such as the number, of the system message in which the system message update occurs.

Step 2: The network side device carries the system message update indication information through the Paging.

The content carried by the system message update indication information may be:

1bit indication information, indicating only that the system message is updated; or

The N bit indicates information indicating a system message identifier (such as a number) in which a system message update occurs.

Step 3: The terminal determines the delay configuration information.

The delay configuration information T can be determined in the following ways:

Configuration information determination mode 1: The network side device carries a delay parameter in the paging message;

The configuration information determining mode 2: the network side device carries the delay parameter in the basic system message (that is, the system message transmitted by using the broadcast mode in the system information);

The configuration information determining mode 3: the network side device uses the dedicated signaling to carry the delay parameter;

Configuration information determination mode 4: pre-configure delay parameters in the standard;

Configuration information determination mode 5: The protocol agreement delay parameter is equal to the length of the system message change period.

Then, the terminal determines the time for sending the system message request message according to the delay configuration information, as follows:

If the delay configuration information T is configured with the same delay parameters for all terminals (such as the configuration information determination mode 1, the configuration information determination mode 2, the configuration information determination mode 4, and the configuration information determination mode 5 in step 3), then the delay parameter usage mode is used. Yes: the terminal randomly generates a random number from [0, T]. After the terminal sends a system message request message change indication, the terminal generates the random number as the time for sending the system message request message, and according to the sending system message request message Time gets the updated system message through on-demand.

If the delay parameter T is separately configured for the terminal (such as the configuration information determining mode 3 in step 3), the delay parameter is used in such a manner that the terminal directly generates the sending system message request message according to the delay parameter T, and according to the The time when the system message request message is sent is obtained by the on-demand method to obtain the updated system message.

Step 4: The terminal requests the updated system message by using the on-demand method.

After the time of sending the system message request message determined in step 3 arrives, the UE requests the updated system message by using the on-demand method. The specific request method is as follows:

If the system message update indication information in step 2 is 1 bit, the terminal needs to obtain all system messages of interest through the on-demand method. For example, all the system information identifiers of interest may be carried in the on-demand request, and no identifier may be carried. The network side device determines, based on the request of the terminal, which system messages the UE is interested in.

If the system message update indication information in step 2 indicates the system message identifier of the system message update, the terminal only needs to obtain the system message that is of interest and updated by the on-demand method. That is, the on-demand request carries the identification information of the system information requested by it, such as the number.

For an IDLE (Idle State) terminal, when a system message update is requested to the network through the on-demand method, it may be requested by a specific sequence or code. The specific sequence or code may only carry the indication information that the terminal needs to send the system message by the network side device, and may also carry the identification information of the system message that needs to be sent by the network side device.

For the connected state terminal, when the system message update is requested to the network through the on-demand method, the dedicated message can be passed. For example, the RRC or the MAC request. The dedicated signaling may only carry the indication information that the terminal needs to send the system message by the network side device, and may also carry the identification information of the system message that needs to be sent by the network side device.

Step 5: The network side device delivers the updated system message.

The network side device delivers the updated system message to the terminal by means of dedicated signaling or broadcast mode based on the UE's on-demand request. When the system is delivered, all system messages of interest to the terminal may be delivered, or only system messages that are of interest to the UE and updated may be delivered.

If the network side device is delivered in broadcast mode, during the updated system message validity time, the system message may be directly obtained for other terminals that also need to request the system message but have not sent the on-demand request due to the delay parameter. And cancel the on-demand request that has been triggered.

Embodiment 2: The system message update indication information is carried by the basic system message (ie, the system message transmitted in the system information using the broadcast mode).

As shown in FIG. 9, the method for updating the basic system message according to the embodiment of the present invention includes:

Step 1: The network side device determines that the system message has changed.

Step 2: The network side device carries the system message update indication information through the basic system message.

In future mobile communication systems, system messages are divided into two parts, basic system messages and on-demand system messages. The so-called basic system message refers to the system message transmitted by the broadcast method in the system information. On-demand system messages are system messages that are transmitted using dedicated signaling.

The content carried by the system message update indication information may be:

Step 3: The terminal determines the delay configuration information.

The delay configuration information T can be determined in the following ways:

For the connected state terminal, when the system message update is requested to the network through the on-demand method, it may be requested by dedicated signaling (such as RRC or MAC signaling). The dedicated signaling may only carry the indication information that the terminal needs to send the system message by the network side device, and may also carry the identification information of the system message that needs to be sent by the network side device.

Step 5: The network side device delivers the updated system message.

Embodiment 3: Carrying a system message update indication by dedicated signaling.

As shown in FIG. 10, the method for updating a message through a dedicated signaling system in the embodiment of the present invention includes:

Step 1: The network side device determines that the system message has changed.

Step 2: The network side device carries the system message update indication information by using dedicated signaling.

The system message update indication information is carried by dedicated signaling such as RRC signaling, MAC signaling, and physical layer signaling.

The content carried by the system message update indication information may be:

Step 3: The terminal determines the delay configuration information.

The delay configuration information T can be determined in the following ways:

Configuration information determination mode 5: protocol agreement delay parameter is equal to the length of the system message change cycle;

Configuration information determination mode 6: The set duration is used as the delay configuration information, for example, the set duration is 0.

Step 5: The network side device delivers the updated system message.

It can be seen from the foregoing that, after receiving the system message update indication information from the network side device, the terminal in the embodiment of the present invention sends the network system device to the network side device after the time of sending the system message request message determined according to the delay configuration information arrives. Send a system message request message. After the terminal receives the system message update indication information from the network side device, not all terminals simultaneously send a system message request message to the network side device, so that when the system message is updated, a large number of terminals request the updated network at the same time. System messages to further improve system performance.
