Description

System information updating method and device

Technical Field

The present invention relates to the field of communications, and in particular, to a method and an apparatus for updating system information.

Background

Cellular mobile communication technology has entered the 4G era over a short period of decades, and research into the 5G technology in the future has been undertaken to meet the anticipated future demands for higher, faster, and more up-to-date communications. The 5G will conduct further technical research in terms of higher throughput, more user connections, lower latency, higher reliability, and lower power consumption (including network side equipment and user terminals). Currently, the industry proposes a 5G technical goal: by about 2020, a 1000-fold increase in mobile data traffic per area, a 10-to 100-fold increase in throughput per User Equipment (UE), a 10-to 100-fold increase in the number of connected devices, a 10-fold increase in battery life of low-power devices, and a decrease in end-to-end 5-fold delay are achieved.

Among them, in order to reduce power consumption of system devices and provide radio resource utilization, research is being conducted on system information propagation mechanisms that have been widely adopted in 2G, 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 characteristics are as follows:

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 Management Information Byte (MIB) and System Management Byte (SIB 1) are transmitted in a fixed pre-configured manner (including transmission timing and transmission resources); while other transport blocks are transmitted using pre-scheduling (including transmission opportunities and/or transmission resources), the scheduling information of which is typically in SIB 1;

all system information is continuously broadcasted according to a pre-configuration or scheduling mode;

under the system information transmission mechanism, with the continuous introduction of new technologies, transmission blocks are increased, system information content is increased, and consumed resources are increased. Moreover, the chances that a number of transport blocks for a particular new technology are actually required are relatively limited, and the constant broadcast transmission results in wasted resources and increased power consumption of the network side device.

In view of the above problems, a possible new system information transmission mechanism is as follows:

system information is divided into two types according to the importance degree of the information, one type is key system information (ongoing system information), and the information is still transmitted by adopting a broadcasting mechanism; another type of other system information, called non-critical system information, is transmitted on-demand (on-demand) and using dedicated signaling (dedicated signaling) or broadcast or multicast mechanisms. The key system information generally includes very key system information related to initial access and/or cell residence, etc., so that information to be broadcast and transmitted by each cell is greatly compressed, and the information is periodically broadcast; the rest system information adopts a second type, and a dedicated signaling (dedicated signaling) or broadcast (broadcast) or multicast (multicast) transmission mechanism can be adopted, but transmission is carried out according to needs instead of periodic transmission, so that the resource utilization efficiency is improved;

according to a deployment scene, key system information of a plurality of cells can be concentrated on a certain cell for periodic broadcast transmission; fig. 1 is a schematic diagram of broadcast system information broadcast transmission according to the related art, and as shown in fig. 1, the macro cell 1 of the new RAT and the small cells cell 2 and cell3 within the coverage of the macro cell, and the key system information of the macro cell 1 and the small cells cell 2 and cell3 are all periodically broadcast and transmitted through the macro cell 1. The key System Information of a plurality of cells form a System Information Table (System Information Table), and each Table element, such as SIT1/SIT2/SIT3 …, includes the key System Information of a cell. The key system information of each cell may be acquired through table indexing.

For non-critical system information, each cell may transmit to the UE on demand using a dedicated signaling (dedicated signaling) or broadcast (broadcast) or multicast (multicast) transmission mechanism.

Since the content in the system information may change, a new system information update mechanism needs to be designed for the transmission mechanism of the new critical system information and the non-critical system information. The present aspect is to design a new system information updating mechanism, especially an updating mechanism for critical system information and non-critical system information related to a certain cell itself.

An effective solution is not provided for the problem that a transmission mechanism for new critical system information and non-critical system information in the related art has no new system information updating mechanism.

Example 1

Step 1: the cell and/or the node receives the system updating request to complete the system information updating;

the system updating request received by the cell and/or the node comprises one or more of the following:

updating system information of the cell and/or the node;

the configuration information of the cell and/or node, including the system information change of the cell and/or node, may be changed by the cell and/or node due to a change of various factors such as the number of users in the cell and/or node, the traffic volume, the wireless environment, and the like.

In order to better manage a large amount of system information, the system information, including critical system information and non-critical system information, may be grouped or partitioned, each group or block may be numbered and/or named with identification information, and a value flag (value tag) indicating an update state may be set for each group or block, and each time a group or block of system information is updated, the value tag is changed, for example, the value is increased by 1. Thus, the update of the system information can be managed by a system information group or a system information block.

Updating system information requested from a terminal;

when the system information stored by the UE is no longer valid for a time reason, for example, the system information stored by the UE is not updated within a predefined or configured time of the system, or the UE newly enters a certain cell, for example, the UE restarts or moves into the cell in the cell, the UE sends system information update request information to the cell and/or the node;

for a UE in a radio resource control RRC IDLE state IDLE and/or other states that cannot directly send/receive information to/from a cell and/or a node, referred to as a non-connected UE, the UE needs to send system information update request information through a random access procedure and/or an RRC link establishment procedure. Fig. 8 is a schematic diagram of a Random Access procedure and an RRC connection setup procedure according to an embodiment of the present invention, as shown in fig. 8, where a UE may carry system information update request information in MSG1 or MSG3 of a Random Access Channel (RACH) procedure, or carry system information update request information in an RRC connection setup complete message of the RRC connection setup procedure, or send the system information update request information through a specific RRC message, such as a system information update request message, after the RRC connection setup procedure.

For a UE in an RRC CONNECTED state or other state capable of directly transmitting/receiving information to/from a cell and/or a node, referred to as a CONNECTED UE for short, the UE may transmit system information update request information to the cell and/or the node through a specific RRC message. Or initiate a system information update request through a specific dedicated physical channel, such as PUCCH of LTE system.

The UE may include an update reason, and/or identification information and/or a value tag of one or more system information groups or system information blocks in the system information update request information.

In particular, if system information update request information of a plurality of UEs is received, the cell and/or the node integrates the plurality of requests into one system information update request and forms one updated system information, which includes all the system information update requests.

Step 2: the cell and/or the node sends updated system information to the UE in a broadcast or multicast mode;

in order to improve the resource utilization efficiency as much as possible, update the system information of as many UEs as possible at the same time, and update the system information of all UEs in the coverage area of a cell and/or node as much as possible, where the cell and/or node will send the updated system information to the UEs in a broadcast or multicast manner, fig. 9 is a schematic diagram of a random access procedure and an RRC connection establishment procedure according to an embodiment of the present invention, as shown in fig. 9, which is a broadcast or multicast method based on a notification and window mechanism, and includes:

fig. 10 is a first schematic diagram of a paging occasion according to an embodiment of the present invention, as shown in fig. 10, a transmission window and a window period are predefined or configured for a system information entirety or one or more system information groups/system information blocks, and the transmission window and the window period are a period defined by time and/or a radio frame, a subframe or a timeslot, where the setting of the transmission window includes a start point and a window length, or a start point and an end point; the window period comprises a period length;

the sending window represents system information, or one or more system information groups/system information blocks can only be sent in the period of time, but does not mean that the system information is sent at each window arrival time, or the one or more system information groups/system information blocks are sent; the window period indicates a period in which the transmission window occurs;

the scheme further includes notification mechanisms, such as DRX-based paging mechanisms:

one DRX paging cycle and multiple paging occasions are predefined and/or configured for a cell and/or node, as shown in fig. 10. Wherein, in one DRX paging cycle, there are multiple paging occasions, and according to predefined/preconfigured rules, each UE is configured with one or more paging occasions in each DRX paging cycle; wherein the paging cycle is a period of time defined in terms of time and/or radio frames, subframes, or time slots; the paging occasion is a time point defined by time and/or radio frame, subframe or time slot;

at each configured paging occasion, the UE needs to monitor the associated downlink physical control channel to monitor for paging messages, and a cell and/or node may send a paging message to the UE at that occasion, including a system information update notification.

The scheme further comprises the following steps: each time a cell and/or a node receives a system update request, the cell and/or the node sends a system information update notification to the UE on all paging occasions of one or more subsequent paging cycles, and then sends all system information, or one or more system information groups/system information blocks, in a broadcast or multicast manner in one or more predefined or preconfigured system information sending windows after paging is completed.

Further, the cell and/or the node may include identification information and/or value tag of the system information group or system information block in the system information change notification to explicitly indicate one or more system information groups or system information blocks in which the change occurs and a corresponding change status.

When the transmission window occurs, the cell and/or node will transmit the system information using a broadcast or multicast manner so that multiple UEs can receive the system information. For a system performing service physical channel dynamic scheduling based on a Downlink physical Control channel, a broadcast or multicast UE identity RNTI (radio Network Temporary identity) is used for scheduling and information transmission of service physical channel resources, for example, in an LTE system, PDSCH (physical Downlink Shared channel) dynamic scheduling is performed based on PDCCH (physical Downlink Control channel), and a broadcast or multicast UE identity RNTI is used for scheduling and information transmission of PDSCH channel resources on a PDCCH channel. For systems that transmit broadcast or multicast system information based on a predefined/preconfigured downlink physical channel, the updated system information is transmitted directly using the predefined/preconfigured downlink physical channel broadcast or multicast.

If the cell and/or the node includes the identification information and/or the value tag of one or more system information groups or system information blocks in the system information change notification, the cell and/or the node transmits the latest corresponding one or more system information groups or system information blocks to the UE.

If the cell and/or node does not explicitly indicate the system information group or system information block to be updated in the system information change notification, the cell and/or node autonomously sends the entire system information or the system information group or system information block with an update for a period of time (e.g., a certain predefined or preconfigured system information update period) to the UE.

If the system information updating request information comprises an updating reason value, the cell and/or the node sends different system information groups or system information blocks to the UE according to different reasons; for example, the system information is no longer valid, the entire system information group or system information block is sent to the UE.

If the system information update request message includes the identification information of one or more system information groups or system information blocks and the value tags thereof, the cell and/or the node may compare the value tags of the system information blocks with the value tags corresponding to the corresponding system information groups or system information blocks reserved by the cell and/or the node, and only send the system information groups or system information blocks with different value tags to the UE.

In particular, the cell and/or node may also send a value tag to the UE that identifies the latest update status of these sets or blocks of system information, respectively.

And step 3: the UE receives and completes system information updating;

according to the predefined/configured DRX paging cycle of the cell and/or the node and the configured paging occasion or occasions, the UE can monitor the paging message at each paging occasion, wherein the paging message comprises a system information updating notice. Once the UE receives the system information update notification, the updated system information will be received at one or more system information transmission windows that are predefined or preconfigured thereafter. Correspondingly, for a system for performing dynamic scheduling of a service physical channel based on a physical control channel, a UE receives a downlink physical control channel with a broadcast or multicast UE identity RNTI, and then receives the service physical channel according to scheduling information on the downlink physical channel, thereby receiving updated system information. Such as a UE in an LTE system, receives a PDCCH channel with a broadcast or multicast RNTI and then receives a PDSCH channel according to scheduling information on the PDCCH. For a system that transmits broadcast or multicast system information based on a predefined/preconfigured downlink physical channel, the UE directly receives the predefined/preconfigured broadcast or multicast downlink physical channel and further receives updated system information.

In particular, if the notification message of the system information change includes the identification information of the system information group or the system information block and/or the status flag of the updated status of the system information block, the UE may receive the updated system information in different manners according to different results of comparing the status flag corresponding to the system information group or the system information block in the notification message with the status flag corresponding to the corresponding system information group or the system information block reserved by the UE:

if the part is the same, receiving the updated system information of the broadcast or multicast of the sending window partially or completely;

after the UE receives the updated system information, the UE updates the corresponding system information group or system information block that is stored locally before according to the identification information and/or value tag of the system information group or system information block.

Example 2

the same as example 1;

in order to improve the resource utilization efficiency as much as possible, update the system information of as many UEs as possible at the same time, and update the system information of all UEs in the coverage area of a cell and/or a node as much as possible, where the cell and/or the node will send the updated system information to the UEs in a broadcast or multicast manner, fig. 11 is a schematic diagram of a random access procedure and an RRC connection establishment procedure according to an embodiment of the present invention, which is shown in fig. 11, and is a broadcast or multicast method based on multiple dynamic schedules of transmission occasions, such as paging occasions, and includes:

fig. 12 is a diagram two of paging occasions according to an embodiment of the present invention, as shown in fig. 12, wherein one DRX paging cycle and multiple paging occasions are predefined and/or configured for a cell and/or a node. Wherein, in one DRX paging cycle, there are multiple paging occasions, and according to predefined/preconfigured rules, each UE is configured with one or more paging occasions in each DRX paging cycle; wherein the paging cycle is a period of time defined in terms of time and/or radio frames, subframes, or time slots; the paging occasion is a time point defined by time and/or radio frame, subframe or time slot; at each configured paging occasion, the UE needs to monitor an associated downlink physical control channel, such as a PDCCH channel in the LTE system, to monitor a paging message or other information, and a cell and/or a node may transmit the paging message to the UE or other information at the occasion.

The scheme further comprises the following steps: whenever a cell and/or node receives a system update request, the cell and/or node transmits an updated system message using a broadcast or multicast manner on all paging occasions of the subsequent paging cycle or cycles so that a plurality of UEs can receive the system information. For a system for performing service Physical Channel dynamic scheduling based on a Downlink Physical Control Channel, a broadcast or multicast UE Radio Network Temporary Identity (RNTI) is used to perform scheduling and information transmission of service Physical Channel resources, for example, in an LTE system, a Physical Downlink Shared Channel (PDSCH) dynamic scheduling is performed based on a Physical Downlink Control Channel (PDCCH), and a broadcast or multicast UE identity is used on a PDCCH to perform PDSCH Channel resource scheduling and information transmission.

The cell and/or the node sends all system information or one or more system information groups or system information blocks with changes in a period of time (such as a certain predefined or preconfigured system information updating period) to the UE according to the system information change condition;

And step 3: the UE receives and completes system information updating;

according to the cell and/or node predefining/configuring a DRX paging cycle and the configured paging occasion or occasions, the UE monitors relevant downlink physical channels, such as PDCCH (physical Downlink control channel) in the LTE system, at each paging occasion of the UE to monitor paging messages or other information. Which comprises the following steps: for a system for performing dynamic scheduling of a service physical channel based on a physical control channel, a UE receives a downlink physical control channel with a broadcast or multicast UE identity RNTI, and then receives the service physical channel according to scheduling information on the downlink physical channel, thereby receiving updated system information. Such as a UE in an LTE system, receives a PDCCH channel with a broadcast or multicast RNTI and then receives a PDSCH channel according to scheduling information on the PDCCH.
