In the process of propaganda power management services, network 140, specifically be one or more in radio battery manager 124 and the services battery manager 126, transmit the information relevant, can comprise by high power supply 408 charge levels (output power level just) of MS report, radio frequency (RF) mode initialization of realizing in low charged state by low power supply 408 charge levels of MS report, by MS and possible the reverse link activity collection adjusting of doing in low charged state by MS with power management services.Preserve such information among one or more at least one memory device 304 of at least one memory device 204 of radio battery manager 124 and services battery manager 126.But, in other embodiments of the invention, can report that MS is in low charged state up to MS, just send one or more in these information projects to MS 102 by radio battery manager 124 and services battery manager 126.In response to receiving power management services information, MS 102 is stored information at least one memory device 406 of MS.
When the charge level experience marked change of the power supply 408 of MS (such as MS 102), network 140, specifically be one or more in radio battery manager 124 and the services battery manager 126, determine that significant variation has taken place the charge level of the power supply 408 of (504) MS.For example, radio battery manager 124 and/or services battery manager 126 can determine that MS102 works (506) now in low power source charges level or MS 102 (514) the power source charges level after recovery of working now.The marked change of power source charges level can comprise that the output power level of the power supply 408 that surpasses the horizontal change threshold of output power changes or can comprise that the dropping to of output power level of power supply 408 is lower than the output power level thresholds; But, persons of ordinary skill in the art will recognize that the algorithm that can use other determines that marked change has taken place the charge level of the power supply 408 of MS, can use the algorithm of such other here, and not deviate from the spirit and scope of the present invention.
In one embodiment of the invention, radio battery manager 124 and/or services battery manager 126 can determine that marked change has taken place the charge level of the power supply 408 of MS 102 based on the message that receives from MS.Referring now to Fig. 6,, logical flow chart 600 is provided, according to the embodiment of the invention, illustrate the method for carrying out by MS 102, to the variation of the charge level of the power supply 408 of network 140 notice MS.When logic flow 600 starts from the charge level experience marked change of power supply 408 of MS 102.MS 102 detects (602) to be changed, and hangs down battery charge level or is converted to high battery charge level such as being converted to, and should change via reverse link 108 notice (604) networks 140.Logic flow 600 finishes subsequently.MS 102 can be by coming informing network 140 these variations in the information that sends on the common signal channel of reverse link 108 or by the information that sends on the Traffic Channel of reverse link 108, it may only influence ongoing calling, perhaps may remain valid up to clearly changing always.
Notice can be clearly or is secretively identified the new charge level of MS.For example, the clearly notice of new charge level can comprise the message that is sent to RAN 110, and such as command messages, report is hanged down charge level or the service profile that is associated with new charge level is provided.In another example, notice can comprise charge level that sign is stored in advance or be associated with new charge level and be different from the message of service profile of the service profile of current use in the dark.For example, message one of can the marked network 140 a plurality of service profile that are associated with MS that preserved, are the message of the low power source charges data of MS such as the request network change.The service profile of sign can be identified clearly by MS, and perhaps MS can transmit the identifier that is associated with service profile.In another example, the charge level that notice can comprise clearly or notice has been recovered mobile radio station in the dark.Moreover, notice can comprise the clearly notice about new charge level or the service profile that is associated with new charge level, perhaps can be associated with new charge level and the service profile that is different from the service profile of current use is secretively circulated a notice of new charge level by sign.
In response to receiving notice, RAN 110 transmits one or more in radio battery manager 124 and the services battery manager 126 of the information that receives.When notice identifies the new service profile of using about MS (being MS 102), the service profile of radio battery manager 124 and/or services battery manager 126 searching mark from mobile radio station and user profile database 128 or from least one memory device 204,304 of radio battery manager or services battery manager.In case the data of retrieving, radio battery manager 124 and/or services battery manager 126 memory scans to data (if this data is not also preserved by radio battery manager or services battery manager) and send free RAN to RAN 110 and use so that the information of service to the data of MS to be provided, such as quality of service information with such other relevant service characteristics of service are provided.
In another embodiment of the present invention, network 140 can for example be operated in low power source charges state from determining that MS 102 has experienced the marked change of charge level.In such embodiment of the present invention, network 140 can determine that certainly MS 102 has experienced the marked change of charge level by introducing one or more in the timer 2 06 and 306.That is to say, one or more can being set in the timer 2 06 and 306 by MS 102 and radio battery manager 124 and the mutual respectively value of promising of services battery manager 126, in case timer then, network 140, specifically be radio battery manager 124 and/or services battery manager 126, can suppose that MS works in low power source charges state, avoids the needs that transmit for additional message thus when expiring.That is to say that timer 2 06 and/or 306 can be set to may experience corresponding to the power supply 408 of MS 102 value of the time cycle of charge level marked change.Therefore, timer 26 and/or 306 then can experience marked change corresponding to the power supply 408 of instruct MS 102.
Use interchangeable, line power supply when MS 102 is interim, rather than during the power supply 408 of finite lifetime, MS can be to the full charge power supply 408 of infrastructure reporting, even power supply 408 is not to be full of.In case only operation on power supply 408 of MS 102 beginnings, MS can notify infrastructure MS current battery charge level once more.Replacedly, when using the manpower power supply, MS and power supply 408 can place energy-saving mode.
Network 140 can be stored the information of current charge level of the power supply 408 of relevant MS 102 respectively at least one memory device 204,304 of radio battery manager 124 and/or services battery manager 126.When realizing in such element other elements at network 140, network 140 can during the call active BSC 114, inertia or between rest period mobile radio station and user profile database 128 and/or MSC 118, PCF 116, support node 120 and be connected in the Internet server (not shown) of IP network 122 any one or a plurality of at least one memory device in, the information of current charge level of storing the power supply 408 of relevant MS 102.And then, about having how low data information, battery situations to be processed can login element (not shown) place other subscribers of mobile radio station and user profile database 128 and/or network 140, and store with each MS, and be associated with the data of each this MS.
When the notice that receives indicates MS 102 when being operated in low charged state, perhaps when network 140 when determining that MS work in low charged state, network 140, it specifically is services battery manager 126, can regulate (508) and be delivered to one or more characteristics of the service of MS, this service adjustment causes the minimizing of the electric power amount that will be consumed by MS 102 in the ongoing operation process.In accepting the process of service adjustment, suppose the user of MS, i.e. the service that the user of MS 102 acceptance maybe would rather demote or postpone is as substituting there be a kind of of service fully owing to consumable power source.The example of the service adjustment of the electric power amount that the ongoing operation of minimizing MS 102 is required comprises the adjusting to radio frequency (RF) link of setting up between MS and network 140, the RF link more specifically is a reverse link 108, reduce MS 102 thus and on link, launched the electric power amount that is consumed, also comprise the signaling between MS 102 and the network 103 or the adjusting of its delay, reduce the electric power amount that MS is consumed thus when participating in this signaling.
