Description
[technical field]
The method that the invention relates to a kind of province electric terminals and make the terminal power saving, clearer and more definite, be can save province's electric terminals of energy and the method that makes the terminal power saving when receiving information about a kind of.
[background technology]
Please refer to Fig. 1, be the basic comprising schematic diagram of a kind of terminal (for example mobile phone), terminal 1 generally includes the different module of a plurality of characteristics: radio-frequency module 10, physical layer baseband processing unit 20, upper-layer protocol processing unit 30 and user oriented application layer module 40.For downstream signal, after radio-frequency module 10 receptions of the wireless signal that network sent through terminal 1, wireless signal is sent to physical layer baseband processing unit 20 to be handled, wireless signal is after through the computing of separating mediation decoding, message after handling is issued upper-layer protocol processing unit 30, finally be transferred to user oriented application layer module 40, give the user with final speech, image and data display then.If terminal 1 and personal computer (PersonalComputer, PC) 2 link to each other, and then application layer module 40 is inlayed and is arranged at PC 2.The relation of terminal 1 and network 3 as shown in Figure 2.
MBMS full name multi-media broadcasting service (Multimedia Broadcasting/MulticastService), it is a kind of service of point-to-multipoint, data are sent to a plurality of recipients from a source entity.MBMS is for supporting that mobile TV proposes in the 3G system.In present system, network is by sending MCCH (control channel) and MTCH (Traffic Channel) information on the SCCPCH channel, for realizing this function, the radio-frequency module of terminal and physical layer baseband processing unit at first will successively read the information on the MCCH logic channel (being detailed later), then according to wherein information, read the information content on the MTCH, to realize the function of mobile TV.
MCCH and MTCH are the logic channel that is used for the MBMS business, wherein the MCCH full name is MBMS point-to-multipoint control channel (MBMS point-to-multipoint Control Channel, MCCH), be used for the MBMS transmission Downlink Control Information, the MTCH full name is MBMS point multipoint message traffic channel (MBMS point-to-multipoint Traffic Channel, MTCH), be used for MBMS transmission downlink data information.These two logic channel MCCH and MTCH are mapped on the FACH transmission channel, and FACH is mapped in again on the SCCPCH physical channel.The physical layer of terminal needs to receive continuously SCCPCH, thereby obtains the information on MCCH channel or the MTCH channel.
Sequential relationship between MCCH and the MTCH is specific as follows described:
UTRAN (3G Access Network) repeats to send MCCH information according to predetermined dispatching cycle, and be a fixing dispatching cycle this dispatching cycle.The MCCH scheduling all is general to all business.To provide the TTI when comprising MCCH information and beginning this dispatching cycle.UTRAN will transmit MCCH information in several continuous TTI, so the MCCH transmission of Information will take several TTI.Terminal continue to receive SCCPCH and followingly stops condition of acceptance one of them promptly stops to receive up to satisfying, and stops condition of acceptance and comprises:
1, receives all MCCH information;
2, receive a TTI who does not comprise any MCCH data; Or
3, the information content shows no longer needs further reception (not changing as the business information that terminal is concerned about).
Please refer to Fig. 3, be MCCH message scheduling schematic diagram, wherein different squares of filling content are represented the different content on the MCCH.Comprise access information cycle (Access InfoPeriod), repetition period (Repetition Period) and adjustment cycle (Modification Period) dispatching cycle of MCCH.The MBMS access information transmits on an access information cycle intercycle ground, and complete MCCH information transmits on a repetition period intercycle ground, and the repetition period then is the integral multiple of TTI.The access information cycle is N/one of repetition period, and adjustment cycle is the integral multiple of " repetition period ".
Note that for convenience we do not consider the access information cycle description of back, only consider repetition period and and adjustment cycle.
Please refer to Fig. 4, is that existing terminal is carried out the schematic flow sheet that MCCH receives.Under existing scheme, the situation that terminal is carried out the MCCH reception is such:
Terminal continuously receives the information on the MCCH in each repetition period in each adjustment cycle, stop one of condition of acceptance if in a repetition period, satisfied three, just no longer receive the information on the MCCH at this adjustment cycle in the remaining repetition period so, in the remaining time of same adjustment cycle, just can carry out the measurement of iso-frequency adjacent community, and then according to the measurement situation of co-frequency neighbor cell, whether decision needs to carry out the sub-district gravity treatment; Otherwise, even the information on the MCCH is received in continued access, till receiving.
Under the good situation of this sub-district link-quality, when terminal has been read full the information on the MCCH in the repetition period at an adjustment cycle, so just do not need to continue to read the MCCH of other repetition period in same adjustment cycle, in an adjustment cycle, have only a spot of time need receive the operation of MCCH like this, do not have what problem like this.
Yet, if this sub-district link-quality is relatively poor, situation is just different, on the one hand because link-quality is relatively poor, terminal can't receive MCCH information all the time, therefore can in each repetition period of an adjustment cycle, all must receive MCCH, cause the energy serious waste, and on the other hand, because terminal is the MCCH on the time slot 0 that receives this sub-district all the time, make terminal not have ability to carry out the measurement of other iso-frequency adjacent community during this period of time, unless be equipped with two or more receiver (this situation considers it is very uneconomic from cost) on this terminal.This will this thing happens, under all bad situation of all co-frequency neighbor cell signal qualitys, even the signal quality of iso-frequency adjacent community is better, the condition that meets the sub-district gravity treatment, because terminal does not have to measure the information of iso-frequency adjacent community, the sub-district gravity treatment can't be carried out, and causes terminal for a long time in the bad sub-district of signal quality, the information on the MCCH can't be received, thereby the MBMS business can't be obtained.
To sum up, how under the situation that realizes the mobile TV function, that is to say the information that needs to receive normally on MCCH and the MTCH, can reduce unnecessary reception as much as possible again, to reach purpose of power saving, is technical issues that need to address.
