系统消息发送方法、获取方法及网络侧设备与终端设备System message sending method, obtaining method, network side device and terminal device

技术领域Technical field

本申请涉及无线通信领域，尤其涉及系统消息发送方法、获取方法及网络侧设备与终端设备。The present application relates to the field of wireless communications, and in particular, to a system message sending method, an acquiring method, and a network side device and a terminal device.

背景技术Background technique

在无线通信系统中，通过小区搜索过程与小区取得下行同步后，终端设备还需要获取一系列的系统消息，例如传输参数或信道信息等，才能在该小区内正确地工作。所述系统消息(system information，SI)则以系统消息块(system information block，SIB)的方式被组织，其中，每个SIB可以包含与某个功能相关的一系列参数集合。In the wireless communication system, after obtaining the downlink synchronization with the cell through the cell search process, the terminal device also needs to acquire a series of system messages, such as transmission parameters or channel information, in order to operate correctly in the cell. The system information (SI) is organized in the form of a system information block (SIB), where each SIB can contain a set of parameters related to a certain function.

由于接入同一小区内的终端设备数量繁多类型多样，不同类型的终端设备实现自身功能所要实现的功能也各不相同。由于不同终端设备所要实现的功能不同，因此不同终端设备所要获取的系统消息也各不相同，因此所述SIB可以分为两类，第一类是小区内所有终端设备都需要获取的SIB，而第二类则是则是小区内部分终端设备所需要获取，而另一部分终端设备不需要获取的SIB。为降低传输所述系统消息所带来的无线资源开销，网络侧设备可以周期性广播和/或组播发送第一类SIB，从而使小区内的终端设备不必专门针对该类SIB发送相应的获取请求；并且，所述网络侧设备可以根据终端设备的获取请求单播第二类SIB，从而避免广播和/或组播发送所述第二类SIB所带来的无线资源浪费。Since the number of terminal devices accessing the same cell is various and diverse, the functions that different types of terminal devices implement to implement their own functions are also different. The SIBs can be classified into two types according to the functions to be implemented by different terminal devices. The first type is the SIBs that all terminal devices in the cell need to acquire. The second type is that some terminal devices in the cell need to acquire, while another terminal device does not need to acquire the SIB. To reduce the radio resource overhead caused by the transmission of the system message, the network side device may periodically broadcast and/or multicast to send the first type of SIB, so that the terminal device in the cell does not need to send the corresponding acquisition specifically for the SIB. And the network side device may unicast the second type of SIB according to the acquisition request of the terminal device, thereby avoiding waste of radio resources caused by the broadcast and/or multicast sending the second type of SIB.

但是当同一小区内的终端设备数量较多时，可能会出现大量终端设备请求获取同一个SIB的情况，当多个终端设备请求获取同一个SIB时，网络侧设备需要单播大量重复发送该SIB，仍然会造成无线资源浪费。However, when there are a large number of terminal devices in the same cell, a large number of terminal devices may request to obtain the same SIB. When multiple terminal devices request to acquire the same SIB, the network side device needs to unicast a large number of repeated transmissions of the SIB. It still causes a waste of wireless resources.

步骤101，终端设备确定第一传输请求，所述第一传输请求用于请求第一系统消息。Step 101: The terminal device determines a first transmission request, where the first transmission request is used to request the first system message.

终端设备可以首先判断是否需要获取所述第一系统消息。当判定需要获取所述第一系统消息后，终端设备可以确定第一传输请求。The terminal device may first determine whether the first system message needs to be acquired. After determining that the first system message needs to be acquired, the terminal device may determine the first transmission request.

例如，终端设备可以根据已经接收到的第二系统消息的内容，判断所述第一系统消息是否发发生了变化；当根据所述第二系统消息的内容判定所述第一系统消息的内容已经发生的变化时，所述终端设备可以确定所述第一传输请求。其中，所述第二系统消息可以包括寻呼消息或基本广播和/或组播消息，所述基本广播和/或组播消息是指发送网络侧设备基本配置信息的系统消息。For example, the terminal device may determine, according to the content of the second system message that has been received, whether the first system message has changed; when determining, according to the content of the second system message, that the content of the first system message has been The terminal device may determine the first transmission request when the change occurs. The second system message may include a paging message or a basic broadcast and/or multicast message, where the basic broadcast and/or multicast message refers to a system message that sends basic configuration information of the network side device.

在另一种实现方式中，终端设备也可以在进入所述网络侧设备所对应的小区时，确定第一传输请求。其中，终端设备在进入所述网络侧设备所对应的小区时，可以直接判定所述第一系统消息的内容已经发生了更新，从而确定所述第一传输请求。或者，终端设备可以在进入所述网络侧设备所对应的小区，且满足预设条件时，才判定所述第一系统消息的内容已经发生了更新，进而确定所述第一传输请求。In another implementation manner, the terminal device may also determine the first transmission request when entering the cell corresponding to the network side device. When the terminal device enters the cell corresponding to the network side device, it may directly determine that the content of the first system message has been updated, thereby determining the first transmission request. Alternatively, the terminal device may determine that the content of the first system message has been updated, and then determine the first transmission request, when entering a cell corresponding to the network side device and satisfying a preset condition.

例如，当终端设备进入一个小区后，可以判断所述小区的系统消息的价值标签(valuetag)值与所述终端设备已保存的系统消息的valuetag值是否一致；如果所述小区的系统消息的valuetag值与所述终端设备保存的系统消息的valuetag值不一致；说明所述第一系统消息已经发生变化，那么终端设备可以确定所述第一传输请求。For example, after the terminal device enters a cell, it can be determined whether the value tag value of the system message of the cell is consistent with the value tag value of the system message saved by the terminal device; if the value tag of the system message of the cell The value is inconsistent with the value tag value of the system message saved by the terminal device; if the first system message has changed, the terminal device may determine the first transmission request.

又如，当终端设备进入一个小区后，可以判断已保存的系统消息是否已经超过有效时间时，如果终端设备保存的系统消息已经超过有效时间，那么也可以认为所述第一系统消息已经发生变化，此时终端设备向可以确定所述第一传输请求。其中，所述有效时间可以由无线通信系统预定义；或者，也可以由网络侧设备通过信令通知给所述终端设备；或者，所述也可以预先被保存在所述终端设备内。For example, when the terminal device enters a cell and can determine whether the saved system message has exceeded the valid time, if the system message saved by the terminal device has exceeded the valid time, the first system message may also be considered to have changed. At this time, the terminal device can determine the first transmission request. The effective time may be predefined by the wireless communication system; or may be notified to the terminal device by the network side device by signaling; or the foregoing may also be saved in the terminal device in advance.

当终端设备需要实现与所述第一系统消息的业务时，也可以确定所述第一传输请求。例如，以第一系统消息为与MBMS业务相对应的为例，当所述终端设备需要实现MBMS业务时，可以确定所述第一传输请求。The first transmission request may also be determined when the terminal device needs to implement a service with the first system message. For example, when the first system message is corresponding to the MBMS service, when the terminal device needs to implement the MBMS service, the first transmission request may be determined.

由于在终端设备确定需要获取所述第一系统消息时，网络侧设备可能已经根据其他终端设备的请求在第一信道资源中广播和/或组播发送所述第一系统消息。因此，为节省无线资源，减少网络侧设备重复传输第一系统消息的次数。在确定需要获取所述第一系统消息后，终端设备可以首先监听所述第一信道资源，如果在预定时长内，例如一个传输时间间隔，未能够接收网络侧设备以广播和/或组播方式发送的到所述第一系统消息，那么所述终端设备再确定所述第一传输请求。The network side device may have broadcasted and/or multicasted the first system message in the first channel resource according to the request of the other terminal device, when the terminal device determines that the first system message needs to be acquired. Therefore, in order to save radio resources, the number of times that the network side device repeatedly transmits the first system message is reduced. After determining that the first system message needs to be acquired, the terminal device may first monitor the first channel resource, and if it is within a predetermined time period, for example, a transmission time interval, is unable to receive the network side device to broadcast and/or multicast. Sending to the first system message, the terminal device determines the first transmission request again.

步骤102，终端设备向网络侧设备发送第一传输请求，所述第一传输请求用于请求第一系统消息。Step 102: The terminal device sends a first transmission request to the network side device, where the first transmission request is used for requestingA system message.

在确定需要获取所述第一系统消息后，终端设备可以直接向网络侧设备发送所述第一传输请求。After determining that the first system message needs to be acquired, the terminal device may directly send the first transmission request to the network side device.

所述终端设备设备可以在预留的公共资源上发送所述第一传输请求；或者也可以在所述终端设备设备的专用资源上发送第一传输请求。其中，所述预留的公共资源可以预留给各个终端设备发送传输请求的无线资源，不同的终端设备设备请求获取不同的系统消息时，都可以通过所述预留的公共资源发送相应的第一传输请求。The terminal device may send the first transmission request on a reserved common resource; or may send a first transmission request on a dedicated resource of the terminal device. The reserved public resource may be reserved for each terminal device to send a radio resource for the transmission request. When different terminal device devices request to obtain different system messages, the corresponding public resource may be sent by using the reserved public resource. A transfer request.

可选的，所述第一传输请求可以是携带有第一信标(beacon)的传输请求，或者所述第一传输请求也可以是所述第一信标本身。所述第一信标则被预先设置为与所述第一系统消息相对应，用于请求网络侧设备发送所述第一系统消息。终端设备可以通过发送不同的信标来请求不同的系统消息。Optionally, the first transmission request may be a transmission request carrying a first beacon, or the first transmission request may also be the first beacon itself. The first beacon is preset to correspond to the first system message, and is configured to request the network side device to send the first system message. The terminal device can request different system messages by sending different beacons.

可选的，所述第一传输请求也可以是携带有所述第一前导序列(preamble)的传输请求，或者所述第一传输请求也可以是所述第一前导序列本身。所述第一前导序列则被预先设置为与所述第一系统消息相对应，用于请求网络侧设备发送所述第一系统消息。终端设备可以通过发送不同的前导序列来请求不同的系统消息。Optionally, the first transmission request may also be a transmission request carrying the first preamble, or the first transmission request may also be the first preamble sequence itself. The first preamble sequence is preset to correspond to the first system message, and is used to request the network side device to send the first system message. The terminal device can request different system messages by sending different preamble sequences.

可选的，所述第一传输请求可以是第一调度请求消息，所述第一调度请求消息用于请求所述第一系统消息。所述第一调度请求则被预先设置为与所述第一系统消息相对应，用于请求网络侧设备发送所述第一系统消息。终端设备可以通过发送不同的调度请求来请求不同的系统消息。Optionally, the first transmission request may be a first scheduling request message, where the first scheduling request message is used to request the first system message. The first scheduling request is preset to correspond to the first system message, and is used to request the network side device to send the first system message. The terminal device can request different system messages by sending different scheduling requests.

可选的，所述第一传输请求可以是携带有所述第一系统消息的索引号的无线资源控制连接请求。所述索引号与所述第一系统消息相对应，用于请求所述第一系统消息。终端设备可以通过发送携带不同索引号的无线资源控制连接请求来请求不同的系统消息。Optionally, the first transmission request may be a radio resource control connection request carrying an index number of the first system message. The index number corresponds to the first system message and is used to request the first system message. The terminal device can request different system messages by sending a radio resource control connection request carrying a different index number.

可选的，所述第一传输请求可以是采用第一无线网络临时标识(radio network tempory identity，RNTI)加扰的数据信息。所述第一RNTI与所述第一系统消息相对应，用于请求所述第一系统消息。终端设备可以通过发送使用不同RNTI加扰的数据信息来请求不同的系统消息。Optionally, the first transmission request may be data information that is scrambled by using a first radio network tempory identity (RNTI). The first RNTI corresponds to the first system message, and is used to request the first system message. The terminal device can request different system messages by transmitting data information scrambled using different RNTIs.

可选的，所述第一传输请求可以包括网络侧设备在第一上行传输资源上发送的传输请求。所述第一上行传输资源与所述第一系统消息相对应。终端设备可以通过使用不同的上行传输资源来请求不同的系统消息。Optionally, the first transmission request may include a transmission request sent by the network side device on the first uplink transmission resource. The first uplink transmission resource corresponds to the first system message. The terminal device can request different system messages by using different uplink transmission resources.

可选的，所述第一传输请求可以是携带有所述终端的终端标识的传输请求，或者所述第一传输请求也可以是所述终端标识本身。Optionally, the first transmission request may be a transmission request carrying a terminal identifier of the terminal, or the first transmission request may also be the terminal identifier itself.

步骤103，网络侧设备在接收到所述第一传输请求后，判断是否满足第一预设条件。Step 103: After receiving the first transmission request, the network side device determines whether the first preset condition is met.

网络侧设备在接收到所述第一传输请求后，可以首先判断广播和/或组播发送所述第一系统消息所消耗的第一无线资源量，是否会少于与单播向每一个请求获取所述第一系统消息的终端设备发送第一系统消息所消耗的第二无线资源量；如果所述第一无线资源量少于所述第二无线资源量，那么网络侧设备可以以广播和/或组播方式发送第一系统消息；如果所述第一无线资源量不少于所述第二无线资源量，那么网络侧设备可以单播发送所述第一系统消息。After receiving the first transmission request, the network side device may first determine whether the first radio resource consumed by the first system message is broadcasted and/or multicasted, and whether the request is less than unicast to each request. Obtaining, by the terminal device of the first system message, a second amount of radio resources consumed by the first system message; if the first amount of radio resources is less than the second amount of radio resources, the network side device may broadcast and And transmitting the first system message in a multicast manner; if the first radio resource quantity is not less than the second radio resource quantity, the network side device may unicast the first system message.

其中，所述第一无线资源量少于所述第二无线资源量，可以通过是否满足第一预设条件来判断。所述第一预设条件可以由无线通信系统预定义；或者，也可以由网络侧设备通过信令通知给所述终端设备；或者，所述也可以预先被保存在所述终端设备内。如果能够满足所述第一预设条件，那么就可以认为所述第一无线资源量少于所述第二无线资源量；如果不能满足所述第一预设条件，那么就可以认为所述第一无线资源量少于所述第二无线资源量。The first radio resource quantity is less than the second radio resource quantity, and may be determined by whether the first preset condition is met. The first preset condition may be predefined by the wireless communication system; or may be notified to the terminal device by the network side device by signaling; or the foregoing may also be saved in the terminal device in advance. If the first preset condition is met, the first radio resource amount may be considered to be less than the second radio resource amount; if the first preset condition cannot be met, then the first A wireless resource amount is less than the second wireless resource amount.

由于第一无线资源量不随请求获取所述第一系统消息的终端设备的数量变化而变化，但是第二无线资源量确会随着请求获取所述第一系统消息的终端设备的数量变化而正相关变化。因此会存一个预定数量，网络侧设备接收到的所述第一传输请求的数量；或者，请求所述第一系统消息的终端设备的数量等小于或不大于所述预设数量时，第一无线资源量会大于第二无线资源量。The first amount of the wireless resource does not change according to the number of the terminal devices that request the first system message, but the second amount of the wireless resource does change with the number of the terminal device that requests the first system message. Related changes. Therefore, a predetermined number of the first transmission request received by the network side device may be stored; or, when the number of terminal devices requesting the first system message is less than or not greater than the preset number, the first The amount of wireless resources will be greater than the amount of second wireless resources.

因此，网络侧设备可以统计第一数量；若所述第一数量大于或不小于所述预设数量，则所述网络侧设备以广播和/或组播方式发送第一系统消息；若第一数量不大于或小于所述预设数量，则所述网络侧设备单播所述第一系统消息；其中，所述第一数量可以包括：网络侧设备接收到的所述第一传输请求的数量；或者，请求所述第一系统消息的终端设备的数量等。所述第一数量可以是无线通信系统预定的，可以是其他设备配置个所述网络侧设备的。Therefore, the network side device may collect the first quantity; if the first quantity is greater than or not less than the preset quantity, the network side device sends the first system message in a broadcast and/or multicast manner; The network side device unicasts the first system message, where the number is not greater than or less than the preset number, where the first number may include: the number of the first transmission request received by the network side device Or, the number of terminal devices requesting the first system message, and the like. The first quantity may be predetermined by the wireless communication system, and may be configured by other devices of the network side device.

步骤104，若满足第一预设条件，则所述网络侧设备以广播和/或组播方式发送第一系统消息；若不满足所述第一预设条件，则所述网络侧设备单播所述第一系统消息。Step 104: If the first preset condition is met, the network side device sends the first system message in a broadcast and/or multicast manner; if the first preset condition is not met, the network side device unicasts The first system message.

若满足第一预设条件，网络侧设备可以直接广播和/或组播发送所述第一系统消息；或者，网络侧设备也可以在满足所述第一预设条件且还满足其它预设条件后，再广播和/或组播发送所述第一系统消息。If the first preset condition is met, the network side device may directly broadcast and/or multicast the first system message; or the network side device may satisfy the first preset condition and also meet other preset conditions. Thereafter, the first system message is sent again by broadcast and/or multicast.

由于所述第一信道资源除用于发送所述第一系统消息之外，还可能用于发送其它系统消息等消息，因此，网络侧设备在发送所述第一系统消息时，还可以采用不同的发送方式或指示信息对不同的所述第一系统消息进行区分。例如，网络侧设备可以广播和/或组播发送以所述第一RNTI加扰的所述第一系统消息。The first channel resource may be used to send other system messages and the like, and the network side device may also use different signals when sending the first system message. The sending manner or indication information distinguishes different first system messages. For example, the network side device may broadcast and/or multicast the first system message scrambled by the first RNTI.

若不满足第一预设条件，网络侧设备则可以广播和/或组播发送所述第一系统消息。具体的发送过程在此就不再赘述。If the first preset condition is not met, the network side device may broadcast and/or multicast the first system message. The specific sending process will not be described here.

由于所述第一信道资源及所述第二信道资源除被用于传输所述第一系统消息之外，还可以能被用于传输其他的系统消息或数据。因此，网络侧设备在发送所述第一系统消息时，还可以采用不同的发送方式或指示信息对不同的所述第一系统消息进行区分。The first channel resource and the second channel resource may be used to transmit other system messages or data in addition to being used to transmit the first system message. Therefore, when the first system message is sent, the network side device may further distinguish different first system messages by using different sending manners or indication information.

例如，网络侧设备广播和/或组播发送不同的数据时，可采用不同的RNTI进行加扰，当需要在第一信道资源上发送所述第一系统消息时，就可以采用所述第一RNTI对所述系统消息进行加扰。For example, when the network side device broadcasts and/or multicasts different data, different RNTIs may be used for scrambling. When the first system message needs to be sent on the first channel resource, the first The RNTI scrambles the system message.

由于网络侧设备可能会单播所述第一系统消息，也可能会组播所述第一系统消息，因此在发送所述第一系统消息之前，网络侧设备也可以先单播、组播或广播和/或组播发送第一传输方式指示，所述第一传输方式指示用于指示所述网络侧设备将单播还是广播和/或组播发送所述第一系统消息。The network side device may also unicast the first system message, and may also multicast the first system message. Therefore, before sending the first system message, the network side device may also unicast, multicast, or The first transmission mode indication is sent by the broadcast and/or multicast, and the first transmission mode indication is used to indicate whether the network side device sends the first system message by unicast or broadcast and/or multicast.

例如，所述网络侧设备在发送所述第一系统消息之前，可以先发送所述第一传输方法指示，所述第一传输方式可以用于指示网络侧设备将使用所述第一信道资源或所述第二信道资源的那一部分传输所述第一系统消息。For example, the network side device may send the first transmission method before sending the first system message.The first transmission mode may be used to indicate that the network side device uses the first channel resource or the part of the second channel resource to transmit the first system message.

步骤105，所述终端设备以广播、组播和/或单播的方式接收所述第一系统消息。Step 105: The terminal device receives the first system message in a broadcast, multicast, and/or unicast manner.

终端设备可以同时以广播、组播和/或单播的方式接收所述第一系统消息；或者，终端设备也可以先在第一信道资源上接收所述第一系统消息，如果未接收到网络侧设备单播发送的所述第一系统消息，那么再接收网络侧设备以广播和/或组播方式发送的所述第一系统消息；或者，终端设备也可以先在第二信道资源上接收所述第一系统消息，如果未接收到网络侧设备单播发送的所述第二系统消息，那么再接收网络侧设备以广播和/或组播方式发送的所述第一系统消息。The terminal device may receive the first system message in a broadcast, multicast, and/or unicast manner at the same time; or the terminal device may first receive the first system message on the first channel resource, if the network is not received. The first system message sent by the side device unicast, and then receiving the first system message sent by the network side device in a broadcast and/or multicast manner; or the terminal device may also receive the second channel resource first. And the first system message, if the second system message sent by the network side device is unicast, is received, and then the first system message sent by the network side device in a broadcast and/or multicast manner is received.

例如，当所述第一信道资源与所述第二信道资源为不同的频域资源时，终端设备可以同时在第一信道资源和/或第二信道资源上进行监听，从而确定所述第一系统消息在哪个信道资源上发送；当所述第一信道资源与所述第二信道资源为不同的时域资源时，可以根据二者的时域位置不同，在其中一个信道资源上接收所述第一系统消息；当在所述其中一个信道资源上未接收到所述第一系统消息时，再在另一个信道资源上接收所述第一系统消息。For example, when the first channel resource and the second channel resource are different frequency domain resources, the terminal device may simultaneously perform monitoring on the first channel resource and/or the second channel resource, thereby determining the first On which channel resource the system message is sent; when the first channel resource and the second channel resource are different time domain resources, the channel resource may be received on one of the channel resources according to the time domain location of the two. a first system message; when the first system message is not received on the one of the channel resources, the first system message is received on another channel resource.

由于所述第一信道资源与所述第一信道资源除被用于传输所述第一系统消息之外，还可能会被用于传输其他系统消息或数据，因此，终端设备在第一信道资源或第二信道资源上接收所述第一系统消息时，可以根据信息的发送方式或指示信息确定所述第一信道资源或第二信道资源上传输的消息是否为所述第一系统消息。The first channel resource and the first channel resource may be used to transmit other system messages or data, in addition to being used to transmit the first system message, and therefore, the terminal device is in the first channel resource. Or, when the first system message is received on the second channel resource, whether the message transmitted on the first channel resource or the second channel resource is the first system message may be determined according to the sending manner or the indication information of the information.

例如，终端设备可以根据所述第一信道资源上发送的系统消息是否是采用第一RNTI加扰来判断所述系统消息是否为第一系统消息。For example, the terminal device may determine whether the system message is the first system message according to whether the system message sent on the first channel resource is scrambled by using the first RNTI.

终端设备在发送完所述第一传输请求后，也可以首先判断网络侧设备将以单播发送所述第一系统消息，还是将广播和/或组播发送所述第一系统消息；然后对应在第一信道资源或第二信道资源上接收所述第一系统消息。After transmitting the first transmission request, the terminal device may first determine whether the network side device will send the first system message by unicast, or send the first system message by broadcasting and/or multicast; The first system message is received on a first channel resource or a second channel resource.

例如，在接收到第一传输方式指示后，终端设备可以根据所述第一传输方式指示的内容判定网络侧设备是将以单播发送所述第一系统消息，还是将广播和/或组播发送所述第一系统消息。如果根据所述第一传输方式指示确定所述网络侧设备将广播和/或组播发送所述第一系统消息，那么终端设备就可接收网络侧设备以广播和/或组播方式发送的所述第一系统消息；而不必再去监听所述第二信道资源；如果根据所述第一传输方式指示确定所述网络侧设备将广播和/或组播发送所述第一系统消息，那么终端设备就可以收到网络侧设备单播发送的所述第一系统消息；而不必再去监听所述第一信道资源。For example, after receiving the first transmission mode indication, the terminal device may determine, according to the content indicated by the first transmission mode, whether the network side device will send the first system message by unicast, or whether to broadcast and/or multicast. Sending the first system message. If it is determined that the network side device broadcasts and/or multicasts the first system message according to the first transmission mode indication, the terminal device may receive the network side device to send in a broadcast and/or multicast manner. Notifying the second channel resource; if it is determined according to the first transmission mode indication that the network side device will broadcast and/or multicast to send the first system message, then the terminal The device can receive the first system message that is sent by the network side device unicast; and does not need to listen to the first channel resource.

又如，在接收到第一传输方式指示后，终端可以根据所述第一传输方式指示确定用于传输所述第一系统消息的指定无线资源，然后在所述指定无线资源上接收所述第一系统消息。For another example, after receiving the first transmission mode indication, the terminal may determine, according to the first transmission mode indication, a designated radio resource for transmitting the first system message, and then receive the first radio resource on the designated radio resource. A system message.
