Description
Technical field
The present invention relates to the sleep technology in the mobile communication system, be meant a kind of method that realizes overlaid windows under the sleep pattern especially.
Background technology
IEEE802.16e is a mobile wide-band wire-less accessing system standard in formulation process just.In mobile communication system, the length of stand-by time has very large influence for the one-movement-freedom-degree of terminal.Prolongs standby time can realize that a kind of mode is to adopt battery efficiently by dual mode; Another kind method is to reduce the meaningless power consumption of portable terminal as much as possible.The mobile terminal sleeping pattern that defines in the D5 draft of IEEE802.16e just belongs to a kind of method in back.So-called sleep pattern is a portable terminal in the time interval of consulting in advance with the base station, the temporary transient process of getting in touch with the base station of interrupting of eating dishes without rice or wine.Realize that sleep mode procedures can reduce the transmission request of portable terminal on up link and down link, thereby reduce the power consumption of portable terminal.Hereinafter MSS specially refers to portable terminal, and Serving BS specially refers to the base station that current MSS connects.
MSS can initiatively send sleep request message (MOB_SLP_REQ) request to Serving BS and enter sleep pattern, Serving BS transmission sleep response message (MOB_SLP_RSP) allows or refuses MSS to enter sleep pattern then, also can initiatively send sleep response message (MOB_SLP_RSP) by BS and come requirement MSS to enter sleep pattern.
Sleep pattern alternately is made up of sleeping window (Sleep_window) and listen window (Listen_window).In sleeping window (Sleep_window), MSS does not send upstream data to this Serving BS, but can scan BS.In listen window (Listen_window), MSS and Serving BS down link keep synchronously, intercept receiving the service indication message (MOB_TRF_IND) that Serving BS issues.
Serving BS safeguards the sleep state machine of the MSS that each enters park mode, determines the time of intercept and the length of one's sleep of each MSS.MSS must wake up in time of intercept and receive the service indication message (MOB_TRF_IND) that Serving BS sends, and decides after time of intercept finishes according to the indication of service indication message (MOB_TRF_IND) and to continue to enter sleep pattern or to return normal mode.If MSS does not receive the service indication message (MOB_TRF_IND) that Serving BS sends in time of intercept, then MSS must finish sleep pattern and returns normal mode.
In the up-to-date agreement IEEE802.16e/D5 draft of current I EEE802.16, stipulated the method to set up of Sleep_window and Listen_window under the sleep pattern.Include initial_sleep_window, final_sleep_window_base, Listen_window, nnal_sleep_window_exponent parameter in the MOB_SLP_REQ message that MSS sends when the request sleep pattern.The initial moment (start frame) that also includes above-mentioned 4 parameters and begin to enter sleep pattern in the sleep pattern response message (MOB_SLP_RSP) that Serving BS sends, Serving BS can adopt the parameter size of MSS request according to oneself resource situation, also can stipulate the numerical value of these 4 parameters again.The size setting of sleeping window (Sleep_window) realizes according to following formula:
Initial_sleep_window obtains from sleep response message (MOB_SLP_RSP) message in the following formula.
Final_sleep_window obtains according to following formula:
final_sleep_window＝final_sleep_window_base×2
(final_sleep_window_exponent)(2)
Wherein final_sleep_window_base and final_sleep_window_exponent parameter are to obtain from sleep response message (MOB_SLP_RSP) message.I
0Expression is the lasting time of sleep state for the first time, I
kRepresent the lasting time of sleep state the K+1 time.MSS is after the sleep pattern response message (MOB_SLP_RSP) that receives Serving BS transmission, indication according to sleep pattern response message (MOB_SLP_RSP) enters into sleep pattern at official hour, initial sleeping window is set to initial_sleep_window, receives service indication message (MOB_TRF_IND) during entering listen window then.If not at the business indication of this MSS, then MSS will alternately enter sleeping window state and listen window state in the service indication message (MOB_TRF_IND), the size of sleeping window state is determined by formula (1) and formula (2).
There is following problem about being provided with of sleep pattern window in the 802.16e/D5 draft at present:
Clear and definite planning is not carried out in the concrete setting of window, if initial_sleep_window, final_sleep_window_base, Listening_window, final_sleep_window_exponent parameter are set arbitrarily, then can cause the listen window (Listen_window) of each MSS all to stagger, the overlapping probability of the listen window of two MSS (Listen_window) is very little.Fig. 1 is provided with schematic diagram for the Sleep_window in the D5 draft, and wherein dash area is a listen window, is listen window by the separated time period of shadow part.Can see that in Fig. 1 owing to sleeping window (Sleep_window) reasonably is not provided with, the listen window of each MSS (Listen_window) all staggers.
Therefore, BS must be to this MSS broadcast transmission service indication message (MOB_TRF_IND) during the listen window (Listen_window) of each MSS, like this, when the MSS that enters sleep pattern is many, cause the frequent issuing service indication of BS needs (MOB_TRF_IND) message, so efficient is very low.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of method that realizes overlapping listen window under the sleep pattern, make a plurality of listen window that are in sleep pattern MSS overlapping as much as possible, reduce the number of times of BS broadcast transmission service indication message, thereby the saving interface-free resources is raised the efficiency.
