Description
Technical Field
The present invention relates to the field of communications, and in particular, to a method and an apparatus for updating and receiving broadcast system information.
Background
The cellular mobile communication technology adopts a cellular wireless networking mode, and the terminal and the network equipment are connected through a wireless channel, so that users can communicate with each other during activities. Cellular mobile communication technology has entered the fourth Generation mobile communication system (4th Generation, abbreviated as 4G) era through a few decades of development, and research into the fifth Generation mobile communication system (5th Generation, abbreviated as 5G) technology in the future has been undertaken in order to meet the anticipated future demand for higher, faster, and more recent communications. The 5G communication system will perform further technical research on the aspects of higher throughput, more user connections, lower time delay, higher reliability and lower power consumption (including network side equipment and user terminals). Currently, 5G technical goals have been proposed in the industry, namely, by about 2020, mobile data traffic increase of 1000 times per area is realized, per User Equipment (UE) increase by 10 to 100 times throughput, the number of connected devices increase by 10 to 100 times, low power devices extend the original 10 times battery life, and end-to-end delay is reduced by 5 times.
In order to reduce power consumption of system devices and improve radio resource utilization, research is being conducted on a system information propagation mechanism that has been widely adopted in a second Generation mobile communication system (2th Generation, abbreviated as 2G), a third Generation mobile communication system (3th Generation, abbreviated as 3G), and 4G. In 2G, 3G, and 4G mobile communication systems, the mechanisms by which system information is transmitted are generally similar, although somewhat surprisal in detail. The common features of 2G, 3G and 4G mobile communication systems include the following: each cell transmits system information in a broadcast (broadcast) mode; all system information is transmitted in a broadcasting mode; the System Information is divided into a plurality of transmission blocks according to characteristics and functions, wherein important transmission blocks such as a Management Information Base (MIB) and a System Information Block (SIB) are transmitted in a fixed pre-configuration mode, wherein the pre-configuration mode includes transmission timing and transmission resources; other transport blocks are transmitted in a pre-scheduling manner, and the scheduling information is usually in SIB1, where the pre-scheduling manner includes transmission timing and/or transmission resources; all system information is continuously broadcast in a pre-configured or pre-scheduled manner.
Under the above system information transmission mechanism, with the continuous introduction of new technologies, not only the number of transmission blocks increases, but also the content of system information becomes larger, and the consumed resources also increase. Moreover, the number of transmission blocks for a particular new technology is actually required with relatively limited opportunities, and the continuous broadcast transmission results in resource waste and also increases the power consumption of the network-side device.
For the problem of resource waste caused by a system information broadcasting method in the related art, no effective solution is available at present.

In this embodiment, a method for updating broadcast system information is provided, and fig. 2 is a flowchart of a method for updating broadcast system information according to an embodiment of the present invention, as shown in fig. 2, the flowchart includes the following steps:
step S202, obtaining changed broadcasting system information SITn of cells or nodes and updating a system information table SIT, wherein the SIT in the system information table comprises the broadcasting system information of the cells or the nodes, the number of the cells is one or more, and the number of the nodes is one or more;

The Transmission Point (TP) and the Transmission Reception Point (TRP) are communication devices different from the base station, and the TP and the TRP can perform wireless communication connection with the user equipment and broadcast or transmit related data to the user equipment.
Step S204, sending a change instruction message of the system information table SIT to a cell or a node and broadcasting the SIT, wherein after receiving the change instruction message, the cell or the node broadcasts the system information table to send the changed message to the user equipment.
Alternatively, the above updating method of the broadcast system information may be applied, but not limited, to a scene in which the broadcast system information is transmitted.
Alternatively, the above-mentioned updating method of the broadcast system information may be applied to, but not limited to, a cell or a node capable of communication connection. For example, macro base stations, micro base stations, pico base stations, distributed base stations, macro cells, small cells, TRPs and TPs, etc.
According to the invention, after the broadcasting system information changed by the cell or the node is obtained, the system information table SIT is updated based on the changed broadcasting system information, and then the change indication message is sent to the cell or the node, so that the cell or the node can timely receive the updated system information table SIT to the user equipment.
In the above embodiments of the present invention, broadcast System Information (System Information Table, abbreviated as SIT) of multiple cells or multiple nodes may be acquired through a certain cell or node (e.g., cell 1). Then, the cell1 may assemble and model the acquired SITn into the system information table SIT and broadcast it. It should be noted that, in the embodiment of the present invention, the broadcast system information SITn of a cell or a node may also be assembled to form the system information table SIT through a certain functional entity (Functionality) other than the cell or the node, where the functional entity may perform information interaction with each cell and node in the cell or node.
In all the following embodiments of the present invention, a cell is taken as an example for illustration.
For example, cell1 acquires the broadcast system information SITn of cells or nodes (e.g., cell 2 and cell 3), wherein the broadcast system information SIT2 of cell 2 and the broadcast system information SIT3 of cell 3 may originate from the same base station, or from different base stations.
If the broadcasting system information SIT1, SIT2, and SIT3 of cell1, cell 2, and cell 3 are generated from different base stations, i.e., there is an external communication interface between cell1 and cell 2 and cell 3, SIT2 and SIT3 may be transmitted to the base station 1 corresponding to cell1 through a communication message of the external communication interface. If the broadcasting system information SIT1, SIT2, and SIT3 of the cell, cell 2, and cell 3 are generated from the same base station, cell 2 and cell 3 may transmit SIT2 and SIT3 to cell1 through an internal message.
In the embodiment of the invention, the resource waste caused by continuous broadcasting of the node or the cell is avoided by a mode that one node (or one cell) acquires the broadcasting system information of the node (or one cell) for broadcasting.
After the obtained SITn of the cell or node is assembled into the System information table SIT, the cell1 may also broadcast the SIT at a predetermined broadcast time through a predetermined broadcast channel, where the predetermined broadcast time includes parameters such as a radio System Frame Number (System Frame Number, abbreviated as SFN, Frame offset (Frame offset), Frame length (Frame length), and period (periodicity).
In the embodiment of the present invention, since the broadcasting system information of the node or the cell may be changed after the SIT is broadcasted, the cell1 may determine whether there is changed broadcasting system information in the cell or the node, and if it is determined that there is changed broadcasting system information, obtain the changed broadcasting system information SITn transmitted by the cell or the node.
Optionally, the obtaining of the changed broadcast system information SITn sent by the cell or the node includes: if an external communication interface exists between the current cell or node and the cell or node, sending a change indication message of the system information table through a communication message on the external communication interface; and if no external communication interface exists between the current cell or node and the cell or node, sending a change indication message of the system information table through an internal communication message of the network element, wherein the current cell or node and the cell or node are positioned in the network element.
For example, when the broadcast system information of cell 2 is changed between cell 2 and cell 3, cell1 may acquire the changed broadcast system information SIT2 of cell 2. Wherein, if cell1 and cell 2 are different base stations, cell 2 may send the change broadcasting system information SIT2 to cell1 through a communication message of an external communication interface with cell 1. After receiving the change broadcast system information SIT2, cell1 replaces SIT2 in the previous broadcast system information table SIT with the received change SIT2, and then cell1 broadcasts the SIT after update.
If the cell1 and the cell 2 are the same base station, no external communication interface exists between the cell1 and the cell 2 and the cell 3, and at this time, the change broadcast system information SIT2 of the cell 2 can be acquired through the internal communication message of the network element. After receiving the change broadcast system information SIT2, cell1 replaces SIT2 in the previous broadcast system information table SIT with the received change SIT2, and then cell1 broadcasts the SIT after update.
Optionally, the updating the system information table according to the obtained change broadcast system information SITn of the cell or the node may be: and updating the broadcasting system information of the cell or the node into the SITn in the system information table through a preset functional entity outside the cell or the node.
Specifically, in the embodiment of the present invention, the broadcasting system information SITn changed in the system information table SIT may be changed by a certain functional entity (Functionality) other than a cell or a node (for example, the cell1, the cell 2, and the cell 3 in the above embodiment), and then the updated system information table SIT is sent to the cell1, where before the functional entity system information table SIT, information interaction with the cell1, the cell 2, and the cell 3 may be performed.
After updating the SIT, the cell1 may transmit a change instruction message (SIT modification notification) of the system information table SIT to the above-described cell or node (for example, the cell 2 and the cell 3).
Optionally, the sending the change indication message of the system information table SIT to the cell or the node includes: a change instruction message of the system information table SIT is transmitted to a cell or a node other than the cell or the node which changes the broadcasting system information SITn among the cells or nodes.
Specifically, considering that cell1 has initiated the change information of SIT2 to cell 2 before this, cell 2 already knows that the SIT will be changed, and therefore cell1 may not send the broadcast system information SIT change notification message to cell 2.
In the embodiment of the present invention, when the cell1 sends the broadcast system information SIT change message to the cells 2 and 3, the time for starting to broadcast and send the changed broadcast system information SIT, for example, a time value with SFN as a reference, may also be carried.
It should be noted that, in the embodiment of the present invention, after receiving the message sent by the cell1 and indicating that the information in the system information table SIT is changed, the cell 2 and the cell 3 may also send the change message of the SIT system information to the user equipment UE in the coverage area of the cell 2 and the cell 3 in the form of a paging message within a period of time, so that as many or all user equipment receive the change notification message of the SIT system information as possible, where the cell1 may also send the change message to the user equipment UE in the coverage area of the cell1 in the form of a paging message. And after receiving the SIT system information change notification message, the user equipment UE receives the changed SIT system information.
In the embodiment of the present invention, there may be many factors for triggering SIT update, and in the embodiment of the present invention, at least one of the following factors may be included: the total number of user equipments, UEs of different services, total load of a cell or node, total load of different services, radio transmission environment of a cell or node, status of neighboring cells of a cell or node.
In summary, in the embodiments of the present invention, a certain base station acquires the changed broadcast system information of the cell or the node, updates the system information table according to the changed broadcast system information, and sends a change indication message of the SIT to the cell or the node after updating the system information table, so that the cell or the node sends the changed message to the user equipment broadcast system information table. By adopting the updating method of the broadcast system message provided by the embodiment of the invention, the broadcast system messages of a plurality of base stations can be concentrated on a certain base station to be sent and the changed message can be broadcast to the user equipment in time, so that the probability of obtaining the updated system information table by the user equipment is improved, the resource efficiency of the broadcast system message is also improved, and the energy consumption of the base station equipment and the terminal is also improved.
In this embodiment, a method for receiving broadcast system information is further provided, and fig. 3 is a flowchart of a method for receiving broadcast system information according to an embodiment of the present invention, as shown in fig. 3, the flowchart includes the following steps:
step S302, receiving a change instruction message of the system information table SIT changed broadcast by a cell or a node;
step S304, receiving the updated system information table SIT broadcasted by the cell or node, wherein the SIT is assembled by the broadcast system information SITn of the cell or node, and the cell or node receiving the change instruction message is the same as or different from the cell or node receiving the system information table SIT.
Alternatively, the receiving method of the broadcast system information may be, but is not limited to, applied in a scenario of receiving broadcast system information.
Alternatively, the above-mentioned receiving method of the broadcast system information may be applied to, but not limited to, a mobile terminal device. Such as a cell phone, tablet, computer, etc.
According to the invention, after the broadcasting system information changed by the cell or the node is obtained, the system information table SIT is updated based on the changed broadcasting system information, and then the change indication message is sent to the cell or the node, so that the cell or the node can timely receive the updated system information table SIT to the user equipment.
Specifically, a cell or a node transmits broadcast system information to a certain cell or node (for example, the cell1 in the above embodiment), and then the broadcast system information SITn of the cell or node is assembled to form a system information table SIT through the cell1 and is broadcasted.
Since the cell1 can broadcast the system information table SIT at a predetermined broadcast occasion through a preset broadcast channel. Therefore, when receiving the system information table SIT, the user equipment UE may receive the system information table SIT at a predetermined broadcast occasion through the same channel as the predetermined broadcast channel, where the predetermined broadcast occasion includes a broadcast occasion determined by a radio system frame number SFN, and the broadcast occasion determined by the SFN is determined by the following parameters: starting frame number, frame offset, frame length, period parameter.
After receiving the broadcasted SIT, since the broadcasting system information of the cell or the node may be changed, when the broadcasting system information of the cell or the node is changed, the cell or the node transmits the changed broadcasting system information to the cell1, and the cell1 updates the system information table SIT according to the received changed broadcasting system information. Then, the base station 1 sends a change indication message of the system information table SIT to the cell or the node, so that the cell or the node notifies the user equipment UE that the system information table SIT is updated, and after receiving an update message for updating the SIT, the user equipment UE receives the updated SIT broadcasted by the cell1 according to the received update message.

In the schematic diagram shown in fig. 10, part of the functions of cell1, cell 2, and cell 3, including the generation and management of system messages, are implemented in the same device, for example, in the base station where cell1 is located, and then cell 2 and cell 3 may send SIT2 and SIT3 to cell1 through internal messages by the base station.
Step S603: the macro cell1 broadcasts and transmits a system information table SIT, wherein the system information table SIT comprises SIT1, SIT2 and SIT 3;
specifically, in the macrocell cell1, the cell1 assembles the SIT1 generated by itself and the SIT2 and the SIT3 received from the cell 2 and the cell 3, respectively, to form the SIT, and then broadcasts and transmits the SIT through a broadcast channel.
Further, cell1 may periodically transmit the SIT as per a predefined broadcast.
