A method for realizing quick paging in data service network with high speed packet includes adding the paging indication information ( PII ) with paging message indication and system message update indication on leading part of each forward control channel sent by base station ; confirming whether the paging message for oneself in paging time slot of current forward control channel ( CFCC ) or not or changing in system configuration parameter, according to PII in leading part of corresponding CFCC and monitoring said channel if there is or otherwise not monitoring said channel .
Description
Technical field
The present invention relates to high-speed packet data service (HRPD) networking technology area, be meant a kind of method of HRPD network realization Quick Paging especially.
Background technology
In wireless cellular system, the base station utilizes paging channel to subscriber station control information transmission and paging information.Before the subscriber station control information transmission, the base station will be according to each user's international mobile subscriber identification (IMSI), goes out the paging time-slot of this user's correspondence by the HASH algorithm computation, and send paging information at this paging time-slot to this user.Equally, terminal is utilized the algorithm computation identical with network side to go out self pairing paging time-slot, and is monitored paging information at this paging time-slot also according to the IMSI of oneself.Therefore, terminal needs frequent monitoring seek channel, even and do not send under the situation of beep-page message to terminal in system, terminal also needs frequent monitoring seek channel in order in time to listen to beep-page message, so the terminal power consumption is serious.
Be to reduce the number of times of terminal monitoring paging channel, code division multiple access system mostly adopts the regularly Quick Paging technology of monitoring seek channel time slot at present, and it realizes that principle is identical, below the method for lucid and lively fast paging so that the cdma20001x system is example only.
Referring to shown in Figure 1, in cdma2000 1x system, the paging channel cycle is 1.28s, and each cycle is divided into 16 paging time-slots, and each paging time-slot length is 80ms.Quick paging channel and Forward Paging Channel or Forward Common Control Channel binding send, and quick paging channel shifts to an earlier date the timed sending of 100ms place at each paging time-slot, and quick paging channel slot length is identical with paging time-slot length, also is 80ms.
The quick paging channel of cdma2000 1x system is supported two kinds of speed: 4800bps and 9600bps.Fig. 2 is that example illustrates cdma2000 1x system quick paging channel slot structure with 4800bps speed.Quick paging channel slot comprises paging indication, broadcasting indication and configuration change indication.Wherein, in the paging time-slot after the paging indicating section indicating terminal 100ms whether beep-page message is arranged, if having, need the decode paging time-slot message of back of terminal, otherwise terminal does not respond the beep-page message of back; The broadcasting indication is used to indicate 100ms paging time-slot afterwards whether to include broadcast; Configuration change indication, be used to indicate system configuration message that the paging time-slot after the 100ms sends whether with sent last time consistent, if consistent, the user need not to upgrade again.
In cdma2000 1x system, in each paging channel in the cycle, terminal only need be waken up once at own corresponding Paging Channel Slot, information in this Paging Channel Slot is decoded, if the beep-page message to oneself is determined wherein to include in the decoding back, then carry out corresponding operation, otherwise terminal enters dormancy once more.When base station side has control information transmission or beep-page message will send to this terminal, the base station will send beep-page message at the paging time-slot of this user's correspondence.Simultaneously, for avoiding missing one's own beep-page message, terminal must be in each paging cycle the paging time-slot of self correspondence monitor and decode.But, do not send under the situation of beep-page message in system to this terminal, still need regularly monitoring seek channel of user, so terminal power consumption is still relatively big.
At present, the base station can be by defined forward control channel transmitting system message, beep-page message etc. in the HRPD system.The HRPD system is when using control channel to send beep-page message, adopted slotted mode equally, paging cycle is 5.12s, and the control channel cycle is 426.67ms, and network side and user determine to send or monitor the beep-page message of which paging time-slot equally through the HASH algorithm.
But concerning the HRPD terminal, for avoiding missing the beep-page message of oneself, the HRPD terminal must regularly be monitored each one's own paging time-slot, so the portable terminal power consumption is serious.And, though in the standard in the regulation HRPD system beep-page message can be carried on the forward control channel and send, do not support the Quick Paging method of similar cdma2000 1x system.Simultaneously, because HRPD system forward control channel has adopted sign indicating number to divide the multi-access mode that adds the time-division, so the HRPD system can't adopt the Quick Paging method of cdma2000 and WCDMA system.
