Be described in detail below in conjunction with accompanying drawing 3 pairs of embodiment of the present invention.
Fig. 3 describes the schematic diagram of the system message update of the embodiment of the present invention, as shown in Figure 3, base station in Broadcast Control Channel (BCCH) to terminal transmitting system information updating instruction and/or upgrade after system message.In modification period (n) (the current system update cycle corresponding to mentioned above), system message update instruction is sent to UE by base station, such as, the instruction of this system message update can be carried in beep-page message and send to UE by base station, in modification period (n+1) (the next system update cycle corresponding to mentioned above), base station sends the system message after upgrading to UE, within certain time period in this cycle, base station still can indicate to UE transmitting system information updating according to the default control cycle, wherein, the instruction of this system message update can send once in each control cycle, namely, in the predetermined amount of time of this modification period (n+1), system message update instruction can be sent to UE by base station, wherein, this predetermined amount of time can be whole duration or the part duration of modificationperiod (n+1).Such as, system message update instruction can be sent to UE by beep-page message by base station, namely, above-mentioned control cycle is paging cycle, at this moment, the integral multiple that predetermined amount of time is paging cycle can be set, like this, within a predetermined period of time, base station all sends the paging information carrying system message update instruction in each paging occasion of paging cycle.
In addition, a flag can be increased in system message update instruction, in order to the time indicating UE to read the system message after upgrading, suppose that application scenarios is: base station sends the system message update instruction of this system message update within the current system update cycle to terminal, and in the predetermined amount of time in the next system update cycle adjacent with this current system update cycle, sending the system message after upgrading to terminal in the lump and said system information updating indicates, then the method arranging flag specifically comprises following two kinds of modes.
Mode one: the system message update instruction only for sending within the next system update cycle arranges retransmission identification position; This retransmission identification position is configured for indicating terminal within this next system update cycle, reads the system message after upgrading, or, be used to indicate terminal and read the system message after upgrading within next system update cycle adjacent with this next system update cycle, and/or, be used to indicate terminal by read within this next system update cycle carry retransmission identification position system message update instruction be set to invalid.Such as, if terminal reads system message update instruction first in modification period (n), terminal receives the system message update instruction carrying retransmission identification position in modification period (n+1), wherein, system message update instruction in modification period (n) and modification period (n+1) all indicates the renewal of same system message (namely indicating same primary system renewal process), it is invalid the system message update instruction carrying retransmission identification position received in modification period (n+1) to be set to, now, terminal can start to read this system message upgraded in modification period (n+1).
When terminal receives this system update indication information at modification period (n+1), then terminal is according to retransmission identification position read system information or in next cycle read system information from this cycle.
Mode two: for the system message update instruction sent within the current system update cycle arranges the first flag, and retransmission identification position is set for the system message update sent within the next system update cycle indicates, wherein, the first flag can one of meet the following conditions with retransmission identification position: the first flag is identical with retransmission identification position, the first flag is different with retransmission identification position, the first flag and retransmission identification position according to predetermined relationship instruction with primary system renewal process.Wherein, first flag is configured to be used to indicate terminal within this next system update cycle, reads the system message after upgrading, retransmission identification position is configured to be used to indicate terminal within this next system update cycle, reads the system message after upgrading, or, be used to indicate terminal and read the system message after upgrading in next system update cycle adjacent with this next system update cycle, and, when terminal reads the system message update instruction of carrying the first flag within the current system update cycle, can by read in the next system update cycle carry retransmission identification position system message update instruction be set to invalid.Particularly, retransmission identification position is the extension of the system message update instruction in modification period (n) in order to the system message update instruction in the indicating predetermined time period, like this, in modification period (n), complete Cell searching but do not read system message update instruction UE, instruction can be upgraded, to read the system message after renewal to carry out follow-up operation by read system message in predetermined amount of time in modification period (n+1).Such as, terminal receives the system message update instruction carrying the first flag in modification period (n), and terminal can read this system message upgraded in modification period (n+1), if terminal receives the system message update instruction carrying the first flag in modification period (n), terminal can receive the system message update instruction carrying retransmission identification position in modificationperiod (n+1), when the first flag and retransmission identification position are denoted as same primary system information updating, it is invalid then the system message update instruction carrying retransmission identification position received in modification period (n+1) to be set to, then terminal can start to read this system message upgraded in modification period (n+1).
When terminal receives this system update indication information at modification period (n+1), then terminal is according to retransmission identification position read system information or in next cycle read system information from this cycle.
By the technical scheme that the embodiment of the present invention provides, base station is after the instruction of terminal transmitting system information updating, the system message after renewal and system message update instruction can be sent in the lump to terminal, compared to prior art, ensure that, in the renewal process of system message, all terminals can both obtain the system message after renewal.
Be paging cycle below with control cycle be example, the method provided in conjunction with example 1 and example 2 pairs of embodiment of the present invention is described in detail.
Example 1
As shown in Figure 3, when system message changes, base station is in modification period (n) (corresponding to the current system update cycle above), system message update instruction is carried in beep-page message and sends to UE by paging channel, UE indicates according to this system message update, can receive the system message after upgrading in modification period (n+1) (corresponding to the next system update cycle above).
In the predetermined amount of time of modification period (n+1), base station again can send the instruction of said system information updating to UE in beep-page message, and in modificationperiod (n+1), the system message after upgrading is sent to UE, wherein, the length of modificationperiod (n+1) can be the integral multiple of the cycle of base station transmission system message and the common multiple of paging cycle.
If UE has read system message update instruction in modification period (n) in beep-page message, according to this instruction, the system message after upgrading can be read in modification period (n+1), if this UE reads again system message update instruction in modification period (n+1), then UE can judge the instruction of this system message update, such as, UE can judge whether according to the flag in system message update instruction to read the system message after upgrading, if the first flag of system message update instruction is identical with the retransmission identification position that system message update in modification period (n+1) indicates in modification period (n), then UE can not repeat to read the system message after upgrading, if the first flag of system message update instruction is different from the retransmission identification position that system message update in modification period (n+1) indicates in modification period (n), then UE can judge whether there is certain predetermined relationship therebetween, if there is predetermined relationship in the two, represent that the first flag and the instruction of retransmission identification position are with primary system renewal process, then UE can not repeat to read the system message after upgrading, if there is not predetermined relationship in the two, represent that the first flag and retransmission identification position do not indicate same primary system renewal process, then UE can repeat to read the system message after upgrading.Namely the system message update that UE can judge in modificationperiod (n+1) indicates whether the extension as the system message update instruction in modification period (n), namely judge whether there is corresponding flag in the system message update instruction in modification period (n+1), if had, the repetition of instruction is upgraded before being then, otherwise, be once new system message update process.
If do not arrange the first flag of system message update instruction in modification period (n), in modification period (n+1), only arrange the retransmission identification position of system message update instruction, then this retransmission identification position is used to indicate the repeating transmission of the system message update instruction in the current system update cycle.Now, according to this retransmission identification position, UE judges whether that the process reading the system message after upgrading is: if do not carry retransmission identification position in the system message update indication information that modification is period (n+1), then represent next time new system message update process, terminal needs to read new system message; If carry this retransmission identification position in the system message update indication information that modification is period (n+1), be then designated as this system message update process, terminal needs to read this system message upgraded.
If UE does not read system message update instruction in modification period (n) in beep-page message, and in modification period (n+1), read system message update instruction, UE can judge according to the Value tag in system message, or, in modification period (n+1), read the system message after upgrading according to the instruction of this system message update.
According to above-mentioned implementation method, in the process of system update system message, make all terminals can obtain system message update instruction, especially solve and carry out community access and the terminal that do not receive system message update instruction cannot carry out the problem of system message update, thus, the perfect renewal process of system message, ensure that the entirety of communication system unitizes.
Example 2
In this example, base station and UE upgrade instruction and the system message after upgrading according to the method read system message shown in Fig. 3, this example can illustrate the available point of base station and UE work, that is, base station and UE start moment of carrying out communicating according to the configuration information in the system message after upgrading.
If base station is transmitting system information updating instruction first in modification period (n) (corresponding to the current system update cycle), and in the predetermined amount of time of modification period (n+1), send the system message after upgrading and the instruction of this system message update in the lump, then can be set effective is some the starting point moment of modification period (n+1) (corresponding to the next system update cycle), and namely the initial time in the cycle sending the system message after upgrading is put in base station is available point.The flag of system message update instruction in modification period (n+1), expression is the extension of system message update instruction in modification period (n), represents that this period belongs to the system message update time and the system message upgraded is invalid or this end cycle is effective.
In the available point moment, the system message that system and UE put after renewal is simultaneously effective, system message simultaneously after system side and the config update of UE side, system side carries out transfer of data according to the configuration information in the system message after renewal, and UE carries out transfer of data according to the configuration information in the system message after renewal.
Example 3
In this example, base station and UE upgrade instruction and the system message after upgrading according to the method read system message shown in Fig. 3, similar with example 2, and this example can illustrate another available point of base station and UE work.Distinguish with example 2 and be: in example 2, being set effective is some the starting point moment of modification period (n+1) (corresponding to the next system update cycle), and the length that can arrange modification period (n+1) is: the integral multiple of the transmission cycle of system message and the common multiple of paging cycle.
In this example, as shown in Figure 5, if base station is transmitting system information updating instruction first in modification period (n) (corresponding to the current system update cycle), and in the predetermined amount of time of modification period (n+1), send the system message after upgrading and the instruction of this system message update in the lump, then can be set effective is some the starting point moment of modification period (n+2) (corresponding to the next system update cycle that the next system update cycle is adjacent), namely, be set effective is some the end point moment of modification period (n+1).Preferably, can utilize retransmission identification position or the instruction of the first flag from the starting point of modification period (n+2), the system message after renewal is effective.In the available point moment, the system message that system and UE put after renewal is simultaneously effective, system message simultaneously after system side and the config update of UE side, system side carries out transfer of data according to the configuration information in the system message after renewal, and UE carries out transfer of data according to the configuration information in the system message after renewal.In addition, before the system message after arranging renewal is effective, base station and terminal all can communicate according to the configuration information in current system message.
