Below by drawings and Examples, technical scheme of the present invention is described in further detail.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the present invention, and be not used in qualification the present invention.
LTE system information update method of the present invention, base station and system, adopt based on the update mode of label (value tag) and " bit " indication SIB different with available technology adopting, the present invention adopts chained form system information updating mode, below by Fig. 1-Fig. 6 to each embodiment of method of the present invention, base station and system explanation that makes an explanation.
Method embodiment
Fig. 1 is embodiment one flow chart of the LTE system information update method according to the present invention, and as shown in Figure 1, present embodiment comprises:
Step S102: in each SIB that need upgrade, be provided for pointing to the next indication information that needs the SIB of renewal;
Step S104: the indication information among the SIB of Geng Xining as required, carry out system information successively and upgrade;
Step S106: whether the renewal process of judging system information finishes, if for not, then forward step S104 to and continue to carry out the renewal of system information according to the indication information among the SIB, if for being the renewal process end.
The method for updating system of present embodiment adopts chain type that update mode is set, as: the base station can be provided with the indication information of some bits in each SIB that need upgrade, be used to the SIB that indicates next needs to upgrade.System information is upgraded initially from SIB1 each time, and the indication information among the SIB1 points to the next SIB that upgrades of needing, and next the indication information among the SIB of this renewal then points to needs the SIB that upgrades, and the like.Next also point in the indication information among the SIB that needs upgrade needs the SIB that upgrades, and then expression is upgraded and finished, and the information that continues is as indicated upgraded, and the indication information in the SIB that next needs to upgrade does not point to, and expression is upgraded and finished.
The update method that present embodiment adopts simply, only needs less signaling consumption can finish system update, compared with prior art, can reduce signaling consumption, update mode simple, can make terminal avoid receiving unnecessary system information simultaneously, normally upgrade needed system information.
Fig. 2 is the embodiment two process of analysis figure of the LTE system information update method according to the present invention, as shown in Figure 2, and the SIB for needing to upgrade of light color in the present embodiment, dark SIB for not upgrading.Some " bit " indication information is set in each SIB that need upgrade.Information updating each time is initial from SIB1, and indication information among the SIB1 points to the next SIB that upgrades of needing, and next the indication information among the SIB of this renewal then points to needs the SIB that upgrades, and as shown in Figure 2, renewal can be adopted following dual mode:
Mode 1: the indication information that this kind mode is provided with in the SIB of each renewal, promptly number of bits can be calculated by total SIB number, and points to the next identification information that needs the SIB that upgrades, is 5 as the identification information of SIB5.As shown in Figure 2, indication information is 2 → SIB2 among the SIB1; Indication information is 5 → SIB5 among the SIB2; Indication information is 8 → SIB8 among the SIB5, and the like;
Mode 2: the indication information that this kind mode is provided with in the SIB of each renewal (bit) is the increment information of sign and this SIB sign of the next SIB that need upgrade.As shown in Figure 2, the bit of indication information is 1 among the SIB1, i.e. SIB1 → SIB2; The SIB2 indication information is 3, i.e. SIB2 → SIB5; The SIB5 indication information is 3, i.e. SIB5 → SIB8.
Terminal can be according to the indication information that reads among each SIB, and promptly the SIB of next bar renewal reads normal updating system information.
Adopt indication information to carry out in the dual mode of information system renewal, indication information can be pressure or optional, promptly in existing protocol, can require all need reserve among each SIB the corresponding bits position as indication information, perhaps require to reserve the corresponding bits position again as indication information among the SIB of each variation, its reserved bit figure place should be able to cover all SIB information.With existing " 3GPP Release 8 " system is example, has 11 SIB in this system, and when wherein other SIB changed, SIB1 necessarily changed.Identify other 10 SIB and need in SIB information, introduce 4 bits (4 bits can identify 16 different SIB information altogether) at most.Under existing situation, need 4 bits at least as indication information.
Fig. 3 is the embodiment three signaling process figure of the LTE system information update method according to the present invention, and idiographic flow describes in conjunction with Fig. 2.Fig. 3 is applied in renewal signaling process figure in 3G or the 4G system for the present invention, as shown in Figure 3, comprises portable terminal (User Equipment is called for short UE) and base station (eNB), and present embodiment comprises:
Step S302:eNB is provided with the indication information that points to next bar SIB in the SIB of each renewal, eNB broadcast transmission MIB and SIB message, and as shown in Figure 2, the SIB of renewal is SIB1, SIB2, SIB5, SIB8...;
Step S304:UE receives the MIB signaling of broadcasting, receives SIB1, reads the indication information among the SIB1, knows the SIB2 that is of next bar renewal;
Step S306: read SIB2 according to the information among the SIB1, obtain system update information, and read the indication information among the SIB2 simultaneously, know the SIB5 that is of next bar renewal;
Step S308:UE is according to the information among the SIB2, skips SIB3 and SIB4 and directly reads SIB5 and carry out system information and upgrade, and obtain the SIB8 that is that next bar upgrades;
Step S310:UE is according to the indication information among the SIB5, skips SIB6 and SIB7 and directly reads SIB8 and carry out system information and upgrade, if the indication information of SIB8 is also meaningful, then is linked to SIB that next bar upgrades and carries out system information and upgrade, and the like; If the indication information of SIB8 does not have content or SIB8 by the mode of indication, represent the follow-up system information block that does not have renewal, the system update process finishes.
Need to prove, the indication information of each step in the present embodiment can adopt among the embodiment two mode 1 and mode 2 dual modes to carry out system information to upgrade and be provided with, particular content please see embodiment two for details, no longer same or similar content is repeated in this description at this.
It is as follows to calculate signaling consumption at the technical scheme of said system update method below:
With existing Release 8 systems is example, has 11 SIB in the existing system, and when wherein other SIB changed, SIB1 necessarily changed.Identify other 10 SIB, need in SIB information, introduce 4 bits (4 bits can identify 16 different SIB information altogether).
The poorest situation is that each SIB all changes in the scheme, and SIB subsequently 1/2 changes, and the overhead bit in the 80ms of this moment is:
4(bit,SIB1)+4(bit,SIB2)*1/2+4(bit,SIB2)*1/4+......+4(bit,SIB2)*1/1024=8bit。
