Description
Technical Field
The present invention relates to the field of mobile communication technologies, and in particular, to a multi-carrier communication system (e.g., LTE-a multi-carrier system) and a method for updating system messages thereof.
Background
In the LTE system, the base station broadcasts a system message to the terminal, informing the terminal of some common parameters related to the cell. The system messages are divided into MIB (master information block) and SIB (system information block). The MIB carries system information transmitted on a BCH (broadcast channel), including information such as downlink system bandwidth and system frame number. SIB includes SIB1 to SIB 13.
The SIB1 carries parameters related to cell access and other system information scheduling, including TAC (tracking area code), cell ID, value tag, scheduling information and mapping information of other SIBs, and the like. The value tag in SIB1 is used to indicate whether the system information except for MIB and SIB1 has been modified, and the terminal determines whether there is a change in the system information by comparing whether the newly received SIB1 is the same as the value tag in the stored SIB1 after losing service.
The SIB2 carries parameter configurations of the cell common channel and the shared channel, such as: random access parameters, reference signal power, physical uplink control channel configuration, physical uplink shared channel configuration, uplink power control parameters, and the like.
The SIB3 to SIB8 carry some parameter information for cell selection and reselection by the terminal in an idle state.
The modification of the system message in the LTE system is notified to the terminal through a paging message. When the terminal senses the paging message, if the system message modification indication field in the read paging message is TRUE, it indicates that there is a modification to the system message in the next system message modification period, and the terminal starts to read the value tag of SIB1 in the next system message modification period. If the value tag is modified, the relevant system message is re-read according to the connection status and the scheduling of the system message in the SIB 1. If the value tag is not changed, the terminal ignores the paging modified by the system message.
In an LTE-a (long term evolution advanced) system, in order to support a higher transmission rate, two or more component carriers (component carriers) are aggregated to support a downlink transmission bandwidth greater than 20MHz (maximum 100MHz), that is, multiple carriers are aggregated (CA). A terminal UE of an LTE-a system may receive two or more component carriers simultaneously according to its capability.
In the LTE-a system, a backward compatible component carrier, a non-backward compatible component carrier, and an extension component carrier that may be introduced are currently defined. The system messages are broadcast on both the backward compatible component carrier and the non-backward compatible component carrier. One LTE-a terminal may aggregate multiple backward compatible component carriers or multiple non-backward compatible component carriers. System message updates may occur for carriers aggregated by the terminal UE.
For carrier scheduling, there are two methods. The first method is that the base station first configures the carriers that the UE can use through a configuration procedure, and then activates the carriers currently used by the UE through an activation procedure, as shown in fig. 1. The second method is to configure which component carriers the UE uses directly through a configuration procedure, as shown in fig. 2. The configuration process is implemented by RRC (Radio Resource Control) signaling, and the activation process may be implemented by RRC signaling, MAC (media access Control) Control unit, or PDCCH (Physical Downlink Control Channel) signaling.
In the first method described above, frequent use of reconfiguration in the second method can be avoided by introducing the activation procedure so that the RRC signaling size can be reduced, and thus battery consumption can be reduced by rapid activation/deactivation. In the second method described above, it is relatively simple to implement because there is no activation/deactivation process. At present, no argument has been made as to which of the two approaches described above is in question.
For the system message update on the activated carrier configured to the UE or the scheduled carrier configured to the UE in the two methods, in order to save power, there is a scheme that the UE monitors only a system message update indication message on one activated or scheduled component carrier, and the indication message may indicate or does not indicate which specific component carrier system message is updated. And when the UE receives the system message updating indication message, updating the system message of the corresponding carrier. So for configured and activated carriers, or configured and scheduled carrier system message updates, can be implemented by this mechanism.
However, in both of the above methods, there may be carriers configured to the UE that the UE does not schedule on.
For example, in the first method, for a carrier configured for the UE but not activated, the UE does not receive any information on the carrier for power saving, so the UE does not check whether the value tag in the SIB1 on the deactivated carrier is modified, and does not care about whether the system message on the carrier is updated.
For example, in the second method, for a carrier configured for the UE to use but not scheduled on, the UE may not receive any information on the carrier, so there is a similar problem to the first method.
However, in order to keep the latest system message when the carrier is activated or scheduled, the UE needs to have a mechanism to notify the UE of the configuration but not the activated carrier or configuration and not the updated system information of the scheduled carrier.
Disclosure of Invention
The technical problem to be solved by the present invention is to provide a multi-carrier communication system and a method for updating system messages thereof, which solve the problem that a terminal cannot timely acquire system messages on configured but not activated carriers or configured but not scheduled carriers.

Further, the configuring, by the network side, the updated system information to the terminal through the signaling message means that the network side configures the updated system information to the terminal through the radio resource control message.

and the network side configures the updated system information to the terminal through the radio resource control message only after the system information is updated and the terminal needs the updated system information.
For a configured but inactive carrier, when the terminal needs updated system information, it means that the terminal needs to perform service scheduling on the carrier and activate the carrier;

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings.
The invention provides a multi-carrier communication system (such as an LTE-A multi-carrier system) and a method for updating system information thereof, aiming at the problem that a terminal cannot timely acquire the configured but unactivated carrier or the system information on the configured but unscheduled carrier in the existing LTE-A system. According to the invention, when the system message on the carrier which is not activated or configured but not scheduled is updated or after the update, the terminal activates or schedules the corresponding carrier and receives the updated system message thereon, or the network side directly configures the updated system message to the terminal.
The method for updating the system message comprises the following steps:
when the system information on the carrier which is configured but not monitored by the terminal is updated or after the system information is updated, the configured carrier which is not monitored is started, and the terminal acquires the updated system information by monitoring the started carrier; or the network side configures the updated system information to the terminal through a signaling message.
Wherein the configured but not sensed carrier is a configured but not activated carrier or a configured but not scheduled carrier.
(1) When the configured and non-monitored carrier is enabled for the configured but non-activated carrier, the network side sends an activation indication to the terminal to activate the configured but non-activated carrier, or the terminal activates the configured but non-activated carrier after receiving the paging message.
The terminal activates the configured but inactive carrier after receiving the paging message, which means that the terminal activates the configured but inactive carrier according to the paging message on the activated carrier after receiving the paging message on the activated carrier.
The terminal activates the configured but not activated carrier corresponding to the indication according to the carrier indicated in the paging message on the activated carrier;
the terminal activates all configured but inactive carriers after receiving the paging message on the activated carrier.
After the terminal acquires the updated system message of the configured but inactivated carrier, the network side sends a deactivation instruction to the terminal or the terminal deactivates the carrier.
(2) For configured but not scheduled carriers, enabling configured but not monitored carriers means that the terminal starts to monitor updated system messages on the configured but not scheduled carriers after receiving the paging message;
the terminal monitors according to the carrier wave indicated in the received paging message, or the terminal monitors all the carrier waves configured to the terminal after receiving the paging message.
And the network side configures the updated system information to the terminal through the radio resource control message. Wherein:
and after the system information is updated, the network side configures the updated system information to the terminal through the radio resource control message.
And the network side configures the updated system information to the terminal through the radio resource control message only after the system information is updated and the terminal needs the updated system information.
In order to enable the UE to acquire configured but not activated carriers or configured and not updated system information of carriers scheduled thereon, the present invention provides the following specific implementation methods:
method A
When the configured but not activated carrier or the configured but not scheduled carrier is updated with the system information, after the configured but not activated carrier is used by the activated terminal or after the terminal receives the paging message, the terminal monitors and acquires the updated system information on the corresponding carrier.
When the activation terminal uses the configured but inactive carrier, the network side sends an activation instruction to the terminal to activate, or the terminal activates itself after receiving the paging message. The terminal activates itself after receiving the paging message, which means that the terminal activates itself after receiving the paging message on the activated carrier. The terminal activates the inactivated carrier wave corresponding to the indication information according to the indication information in the received paging message; or the terminal activates all the inactivated carriers after receiving the paging message.
After the terminal receives the paging message, the terminal monitors and acquires the updated system message on the corresponding carrier, which means monitoring the carrier indicated in the paging message or the system information on all carriers configured to the terminal.
Further, after the terminal acquires the updated system message on the configured but inactivated carrier, the network side sends a deactivation indication to the terminal or the terminal deactivates the carrier.
Method B
When the configured but not activated carrier or the configured but not scheduled carrier is updated with the system information, the network side configures the updated system information to the terminal through a Radio Resource Control (RRC) dedicated signaling. Wherein the Radio Resource Control (RRC) dedicated signaling is a Radio Resource Control (RRC) connection reconfiguration message.
Method C
When the system information of the configured but not activated carrier or the configured but not scheduled carrier is updated, and the terminal is only judged to need the updated system information at the network side, the updated system information is configured to the terminal through a Radio Resource Control (RRC) dedicated signaling. Wherein the Radio Resource Control (RRC) dedicated signaling is a Radio Resource Control (RRC) connection reconfiguration message.
When the network side determines that the terminal needs to update the system information, the determining means that the network side determines whether the system information of the configured but not activated carrier or the configured but not scheduled carrier is updated before and after the terminal is activated or scheduled.
The following embodiments are further explained for the system message update method in the LTE-a system.
Example 1: with method a, an activation command is used for configured but inactive carriers.
The cell downlink of the LTE-a system has 3 component carriers, which are downlink component carriers F1, F2, and F3, respectively. All 3 component carriers of the cell are backward compatible component carriers and carry system messages. As shown in fig. 3, the LTE-a UE configuration in connected state uses downlink component carriers F1, F2, and F1 is activated and F2 is not activated for the UE downlink component carrier. At this time, the UE only listens to the system message on the downlink component carrier F1 for updates, but does not listen to the system message on F2 for updates.
When the system message on the downlink component carrier F2 of the cell is modified, the base station activates the UE to use the component carrier F2 through signaling (which may be RRC signaling, MAC control element, PDCCH signaling).
After the component carrier F2 is activated, the UE starts to listen to the system message on F2 for updates by listening to the paging message or value in SIB 1. And if the system message is updated, the UE reads the new system message.
After the UE reads the new system message, the base station deactivates the UE using the component carrier F2 through signaling.
Example 2: with method a, no activation command is used for configuring the inactive carriers.
The LTE-a cell downlink has 3 component carriers, which are F1, F2, and F3, respectively. The component carrier F1 of the cell is a backward compatible component carrier, and F2 and F3 are non-backward compatible component carriers, both carrying system messages. As shown in fig. 4, the LTE-a UE configuration in connected state uses downlink component carriers F1, F2, and F1 is activated and F2 is not activated for the UE downlink component carrier. At this time, the UE listens only to the system message on F1 for updates, and does not listen to the system message on F2 for updates.
When the system message is modified on the cell component carrier F2, the base station sends a paging message for system message update on the component carrier F1.
The UE receives the paging message of system message update on the component carrier F1, judges that the carrier F2 has system message update according to the indication in the paging message, and activates the component carrier F2 by the UE. Or the UE activates all inactive carriers as soon as it receives the paging message.
The UE starts to listen for updates of system messages on F2 by listening to the value tag in SIB1 on component carrier F2. And if the system message is updated, the UE reads the new system message.
After the UE reads the new system message, it deactivates the UE using component carrier F2.
Example 3: with method a, carriers that are configured but not scheduled are targeted.
The LTE-a cell downlink has 3 component carriers, which are F1, F2, and F3, respectively. All 3 component carriers of the cell are non-backward compatible component carriers and carry system messages. As shown in fig. 5, the LTE-a UE configuration in connected state uses downlink component carriers F1, F2, and the base station schedules the UE on the downlink component carrier F1. At this time, the UE listens only to the system message on F1 for updates, and does not listen to the system message on F2 for updates.
When the system message is modified on the cell component carrier F2, the base station sends a paging message for system message update on the component carrier F1.
The UE receives the paging message of system message update at F1, determines that the carrier F2 has system message update according to the indication in the paging message, and starts to monitor the system message update on the component carrier F2. Or the UE starts to listen to system message updates on all configured carriers as soon as it receives the paging message.
The UE starts to listen for updates of system messages on F2 by listening to the value tag in SIB1 on component carrier F2. And if the system message is updated, the UE reads the new system message.
After reading the new system message, the UE stops listening to the system message update on the component carrier F2.
Example 4: with method B, the carrier type is a configured but inactive carrier.
There are 3 component carriers in the LTE-a cell downlink, which are component carriers F1, F2, and F3, respectively. All 3 component carriers of the cell are backward compatible component carriers and carry system messages. As shown in fig. 6, the LTE-a UE configuration in connected state uses downlink component carriers F1, F2, and F1 is activated and F2 is not activated for the UE downlink component carrier. At this time, the UE listens only to the system message on F1 for updates, and does not listen to the system message on F2 for updates.
When the system message on the cell component carrier F2 is modified, the base station configures the updated necessary system information to the UE through RRC dedicated signaling.
The UE updates the stored system information about component carrier F2 so that even if the carrier is inactive, it is guaranteed that the UE stores the latest system information.
Example 5: with method B, the carrier type is the configured but unscheduled carrier.
There are 3 component carriers in the LTE-a cell downlink, which are component carriers F1, F2, and F3, respectively. All 3 component carriers of the cell are non-backward compatible component carriers and carry system messages. As shown in fig. 7, the LTE-a UE configuration in connected state uses downlink component carriers F1, F2, and the base station schedules the UE on the downlink component carrier F1. At this time, the UE listens only to the system message on F1 for updates, and does not listen to the system message on F2 for updates.
When the system message on the cell component carrier F2 is modified, the base station configures the updated necessary system information to the UE through RRC dedicated signaling.
The UE updates the stored system information about component carrier F2 so that it is guaranteed that the UE stores the latest system information even though no scheduling is performed on the carrier.
Example 6: with method C, the carrier type is a configured but inactive carrier.
The LTE-a cell downlink has 3 component carriers, which are F1, F2, and F3, respectively. All 3 component carriers of the cell are backward compatible component carriers and carry system messages. As shown in fig. 8, the LTE-a UE configuration in connected state uses downlink component carriers F1, F2, and F1 is activated and F2 is not activated for the UE downlink component carrier. At this time, the UE listens only to the system message on F1 for updates, and does not listen to the system message on F2 for updates.
When the carrier F2 is not activated, the system message of the carrier F2 is updated, and the UE does not update the system information related to F2 that the UE holds.
When the base station needs to activate the component carrier F2 because of traffic scheduling or channel quality changes. The base station judges that the system information of the carrier wave is updated before the UE is activated, and configures the updated necessary system information to the UE through RRC dedicated signaling.
The UE updates the stored system information on the component carrier F2, thus ensuring that the UE stores the latest system information of the carrier F2 even when the carrier is activated.
Example 7: with method C, the carrier type is a configured, unscheduled carrier.
The LTE-a cell downlink has 3 component carriers, which are F1, F2, and F3, respectively. All 3 component carriers of the cell are non-backward compatible component carriers and carry system messages. As shown in fig. 9, the LTE-a UE configuration in connected state uses downlink component carriers F1, F2, and the base station schedules the UE on the downlink component carrier F1. At this time, the UE listens only to the system message on F1 for updates, and does not listen to the system message on F2 for updates.
When the UE is not scheduled on carrier F2, the system message of carrier F2 is updated, and the UE does not update its own saved F2 related system information.
When the UE needs to be scheduled on component carrier F2 due to traffic scheduling or channel quality changes. The base station judges that the system information of the carrier wave is updated before the UE is scheduled, and configures the updated necessary system information to the UE through RRC dedicated signaling.
The UE updates the stored system information on the component carrier F2, thus ensuring that the UE stores the latest system information for the carrier F2 even when the carrier is scheduled.

The signaling message is a radio resource control message, and the network side configures the updated system information to the terminal through the radio resource control message.
The specific way that the network side configures the updated system information to the terminal through the radio resource control message includes:
after the system information is updated, the network side configures the updated system information to the terminal through a wireless resource control message; or,
and the network side configures the updated system information to the terminal through the radio resource control message only after the system information is updated and the terminal needs the updated system information.
