Continue with reference to figure 6, one or more Remote Expansion unit (RXU) 160 (1)-160 (Z) also can be connected to RAU14.Except providing except extra RF communication service from RAU14 with remote mode, RXU160 (1)-160 (Z) can also be set to be provided extra RF communication service by RAU14.Such as, if need extra RF communication band and there is not available additional band in distributing antenna system, so can expand the RF communication band of existing RAU14, and without the need to by providing RXU160 (1)-160 (Z) to obtain extra communication band.RXU160 (1)-160 (Z) is connected to distributing antenna system by RAU14.RXU160 (1)-160 (Z) can comprise assembly same or similar with the assembly be arranged in RF communication module 152, with receiving downlink RF signal of communication 162D, and by RAU14, the up link RF signal of communication 162U being received from client terminal device is supplied to distributing antenna system.RXU160 (1)-160 (Z) is also power consumption module, and thus in this embodiment, the electric power from power line 150 is routed to RXU160 (1)-160 (Z) via power line 164 by RAU14.
The electric power be provided on the power line 150 in Fig. 6 may be not enough to provide electric power to the module 152,154,160 (1)-160 (Z) be arranged in RAU14 and outside PD156 (1)-156 (Q).Such as, the power of 80 (80) watts can be provided on the power line 150 in Fig. 6.But RF communication module 152 may consume the power of 30 (30) watts, RXU160 (1)-160 (Z) may consume the power of 20 (20) watts, and DDS module 154 may consume the power of five (5) watts.Like this, 55 (55) watts are total up to.In this example, being used in the power shared between powered communication port one 58 (1)-158 (Q) is 25 (25) watts.But PD156 (1)-156 (Q) can be configured and need to exceed the power of 25 (25) watts.Such as, if configure PD156 (1)-156 (Q) according to PoE standard, be so arranged in RAU14 for providing the power-supply device of electric power (PSE) may need to provide power up to 15.4 watts to each powered communication port one 58 (1)-158 (Q) to powered communication port one 58 (1)-158 (Q).In this example, if be provided with more than one powered communication port one 58 (1)-158 (Q), so just there is no enough electric power to power to each in the powered communication port one 58 (1)-158 (Q) of needs 30 watts (that is, PoEClass4 device).
Therefore, module 152,154,160 (1)-160 (Z) in order to ensure the consumption maximum power that may have in RAU14 carries out proper operation, less electric power can be provided to powered communication port one 58 (1)-158 (Q), or an only powered communication port one 58 (1)-158 (Q) can be enabled with electric power.But, if the one in other modules 152,154,160 (1)-160 (Z) is non-existent, so obtainable electric power is just enough to be supplied to each in set powered communication port one 58 (1)-158 (Q).In addition, if the PD156 being connected to powered communication port one 58 is the lower grade device not needing 30 watts of power, so obtainable electric power is just enough to PD156 (1)-156 (Q) power supply to being connected to each in powered communication port one 58 (1)-158 (Q).
In this respect, Fig. 7 is the exemplary priority scheme of power management scheme, and described power management scheme provides enough electric power for the power consumption module for being powered by RAU14 and PD.In this example, the priority of RF communication service has been assigned to higher than the priority of digital data service with power supply port.Therefore, in this example, the electric power that can obtain from power line 150 will be provided to RF communication module 152.If after making power budget for RF communication module 152, can obtain more electric power from power line 150, so dump power is provided to RXU160 (1)-160 (Z) to provide expansion RF communication service.If after making power budget for RF communication module 152 and RXU160 (1)-160 (Z), can obtain more electric power from power line 150, so dump power is provided to DDS module 154 to provide digital data service.If after making power budget for RF communication module 152, RXU160 (1)-160 (Z) and DDS module 154, can obtain more electric power from power line 150, so dump power is provided to powered communication port one 58 (1)-158 (Q) to provide electric power to PD156 (1)-156 (Q).It should be noted that the priority of planning in Fig. 7 is exemplary, and any other required precedence scheme can be implemented in power management scheme.
Continue with reference to figure 7, the power budget done is, obtainable electric power is enough to PD158 (1) power supply to being connected to the first powered communication port one 58 (1).If after making power budget for RF communication module 152, RXU160 (1)-160 (Z), DDS module 154 and the PD158 (1) that is connected to the first powered communication port one 58 (1), more electric power can be obtained from power line 150, so electric power is provided to other powered communication port ones 58 (2)-158 (Q), until obtainable electric power is not enough to PD156 (2)-156 (Q) power supply to being connected to extra powered communication port one 58 (2)-158 (Q).If dump power budgetary shortfall is to power to the PD156 being connected to any powered communication port one 58, so these powered communication port ones 58 can be stopped using.In addition, if for specific RAU14, any module is had not exist or be removed in module 152,154,160 (1)-160 (Z), so the obtained power budget of powered communication port one 58 (1)-158 (Q) can increase, thus the powered communication port one 58 (1)-158 (Q) of stopping using before enabling.

As shown in Figure 9, in order to provide the electrical management at RAU14 place, have employed the HEC44 in HEU12.Each RAU14, HEC44 are received to the configuration (square frame 180 in Fig. 9) of the power consumption module 152,154,160 (1)-160 (Z) be present in RAU14.HEC44 communicates with RAU14 by using the digital communication transmitted via communication link, and described communication link is identical with the communication link for carrying RF signal of communication.The U.S. Provisional Application case the 61/230th that the title submitted on July 31st, 2009 is " OpticalFiber-BasedDistributedAntennaSystems; Components; andRelatedMethodsforMonitoringtheStatusThereof " is described in about providing the more information of digital communication and control system in distributing antenna system, in No. 472, this application case is incorporated herein by reference in full.HEC44 decides the electric power (square frame 182 in Fig. 9) needed for module 152,154,160 (1)-160 (Z) be present in RAU14 by inquiry memory cell 46.Such as, memory cell 46 can be programmed by the power consumption speed relevant to dissimilar module 152,154,160 (1)-160 (Z), and HEC44 can search described power consumption speed in memory cell 46.
According to the discussion carried out hereinafter with reference to Figure 10, RAU14 can provide specific hardware and/or software element, and/or being present in multiple versions of those elements of the module 152,154,160 (1)-160 (Z) in RAU14, HEC44 can use these elements to decide the electrical power demand of module 152,154,160 (1)-160 (Z).Subsequently, by the electric power that the abundant power supply station of module 152,154,160 (1)-160 (Z) deducted by the total electricity being supplied to RAU14 as existing in RAU14 needs, HEC44 decides the obtained power budget of RAU14 accordingly, thus provides electric power (square frame 184 in Fig. 9) to any PD156 (1)-156 (Q) being connected to powered communication port one 58 (1)-158 (Q).The obtainable total electricity of RAU14 can be programmed in memory cell 46, comprises and is programmed by the graphic user interface (GUI) of HEU12 institute management and control by user or programmed by other configurations.For each RAU14 being configured for use in HEU12, described process can repeat.By performing the process in Fig. 9, RAU14 receives and can obtain power budget, and the described power budget that obtains can provide electric power through point PD156 (1)-156 (Q) be equipped with to being connected to powered communication port one 58 (1)-158 (Q) in RAU14.
RAU14 also performs the process for providing electrical management.Described process can be performed by the controller 176 in the DDS module 154 shown in Fig. 8.Figure 10 be a diagram that the flow chart of the exemplary power management process that RAU14 provides, and described electrical management process is used at initial phase and the electric power managing RAU14 place when the configuration of RAU14 is changed.RAU14 checks the configuration of the module 152,154,160 (1)-160 (Z) be present in RAU14, to determine whether the configuration of RAU14 changes (square frame 190).Such as, after upper once decision configures and configuration is supplied to HEC44, module 152,154,160 (1)-160 (Z) may be added or removes from RAU.If the configuration of RAU14 changes (square frame 192), so RAU14 obtains the hardware and software version (square frame 194) of module type and module 152,154,160 (1)-160 (Z).The hardware and software version of module type and module 152,154,160 (1)-160 (Z) is sent to HEC44(square frame 196 by RAU14 subsequently).In square frame 180 in fig .9, this information is received by HEC44, as before hereinbefore as described in.
Continue with reference to Figure 10, according to the process in Fig. 9, the obtained power budget for RAU14 (square frame 198) that HEC44 provides new waited for by the controller 176 in RAU14.When obtaining power budget described in receiving (square frame 200), controller 174 determines whether DDS module 154 is arranged on (square frame 202) in RAU14.If not, so controller 176 determines whether installed RXU module 160 (1)-160 (Z) (square frame 204).If not, then described process is repeated.If installed RXU module 160 (1)-160 (Z) (square frame 204), so controller 176 has determined whether RXU module 160 (1)-160 (Z) opens (square frame 206).If so, then described process is repeated.If not, so controller 176 indicates RF communication module 152 to open RXU module 160 (1)-160 (Z) (square frame 208), and repeats described process.
Continue with reference to Figure 10, if controller 176 determines to have installed DDS module 154(square frame 202), so just mean that digital data service is provided by RAU14.The powered communication port one 58 existed in this example allows PD156 (1)-156 (Q) to be connected to powered communication port one 58 (1)-158 (Q), thus the digital data service making PD156 (1)-156 (Q) that DDS module 154 can be received to support.In this respect, controller 176 guides PSE170 the obtained power budget being received from HEC44 to be sent to powered communication port one 58 (1)-158 (Q) (square frame 210) in RAU14.According to power budget can be obtained and be connected to the electrical power demand of PD156 (1)-156 (Q) of powered communication port one 58 (1)-158 (Q), can enable or stop using and be connected to the PD156 (1)-156 (Q) of powered communication port one 58 (1)-158 (Q).Controller 176 etc. is connected to the state (square frame 212) of the PD156 (1)-156 (Q) of powered communication port one 58.When the state of the PD156 (1)-156 (Q) being connected to powered communication port one 58 (1)-158 (Q) is received (square frame 214), described state is sent to HEC44(square frame 216 by controller 176).Subsequently, if there is RXU module 160 (1)-160 (Z) and RXU module 160 (1)-160 (Z) is not also opened, so controller 176 is RXU module 160 (1)-160 (Z) power supply (square frame 204,206,208).
Figure 11 be a diagram that the flow chart of the exemplary power management process that RAU14 provides, described electrical management process is used for changing (namely to the state at powered communication port one 58 (1)-158 (Q), connect or disconnect) time manages the electric power being supplied to PD156 (1)-156 (Q), and powered communication port one 58 (1)-158 (Q) is arranged in RAU14.If the state of arbitrary powered communication port one 58 (1)-158 (Q) improves electrical power demand, such as, owing to there is new connection or being connected with the PD156 of the more electric power of needs, so may need other powered communication port ones 58 (1)-158 (Q) inactive, can obtain in the scope of power budget to remain on.If the state of arbitrary powered communication port one 58 (1)-158 (Q) reduces electrical power demand, so can enable other powered communication port ones 58 (1)-158 (Q), this is can obtain in the scope of power budget to remain on equally.
With reference to Figure 11, controller 176 determines whether the configuration of RAU14 changes (square frame 220).If changed (square frame 222), so controller 176 determines whether described change occurs (square frame 224) because of the state change of powered communication port one in RAU14 58 (1)-158 (Q).Although be carry out electrical management to two (2) powered communication port ones 58 (1), 158 (2) in this example, the powered communication port obtaining managing can have any number.If powered communication port one 58 (1)-158 (Q) does not change, so just mean for PD156 (1)-156 (Q) provides the obtained power budget of electric power to change, because at least one module 152,154,160 (1)-160 (Z) has been removed or has been added in RAU14.In this example, controller 176 determines whether PD156 (1) is connected to the first powered communication port one 58 (1) (square frame 226) of not powering.If so, so controller 176 determines whether can obtain power budget is enough to provide electric power (square frame 228) to the PD156 (1) being connected to the first powered communication port one 58 (1).If so, so controller 176 guides PSE170 to provide electric power (square frame 230) to the first powered communication port one 58 (1).If not, so controller 176 checks the state (square frame 232) of the second powered communication port one 58 (2).
If controller 176 determines that the first powered communication port one 58 (1) does not obtain powering (square frame 226), so controller 176 determines whether PD156 (2) is connected to the second powered communication port one 58 (2) (square frame 232) of not powering.If so, so controller 176 determines whether can obtain power budget is enough to provide electric power (square frame 234) to the PD156 (2) being connected to the second powered communication port one 58 (2).If so, so controller 176 guides PSE170 to provide electric power (square frame 236) to the second powered communication port one 58 (2).If not, so controller 176 does not change the electrical arrangement of the second powered communication port one 58 (2).Therefore, controller 176 carrys out managing power in the following manner: can obtain power budget if existed, so enable the first powered communication port one 58 (1), and subsequently, if power budget can be obtained can be obtained after providing electric power to the first powered communication port one 58 (1), so enable the second powered communication port one 58 (2).When RAU14 obtained power budget change time, based on can obtain power budget reappraise enabling of powered communication port one 58 (1), 158 (2) or stop using.
If the state of powered communication port one 58 (1), 158 (2) changes (square frame 224), so the current power setting of powered communication port one 58 (1), 158 (2) is also reappraised.In this respect, if the first powered communication port one 58 (1) is connected (square frame 238), so controller 176 obtains the grade (square frame 240) of the PD156 (1) being connected to powered communication port one 58 (1) from PSE170.Controller 176 determines whether can obtain power budget is enough to the PD156 being in self class rating (1) power supply (square frame 242).If so, so controller 176 guides PSE170 to enable powered communication port one 58 (1), to provide electric power (square frame 244) to the PD156 (1) being connected to powered communication port one 58 (1).Such as, if can obtain power budget is 16 watts, so to being connected to powered communication port one 58 (1) and rated power is PoEClass3PD156 (1) power supply of 15.4 watts, thus powered communication port one 58 (1) can be enabled.But if rated power is 30 watts or less PoEClass4PD156 (1) be connected to powered communication port one 58 (1), so powered communication port one 58 (1) is deactivated, because can obtain power budget to be less than 30 watts.
The RAU14 that controller 176 comes in more new memory 178 based on the grade of the PD156 (1) being connected to powered communication port one 58 (1) can obtain power budget (square frame 246), thus avoids when not remaining enough power budget electric power being guided to the second powered communication port one 58 (2).If can obtain power budget be not enough to be connected to powered communication port one 58 (1) PD156 (1) power supply (square frame 242), so controller 176 is stopped using powered communication port one 58 (1), thus avoids PSE170 electric power to be supplied to powered communication port one 58 (1) (square frame 248).
If PD156 (1) is not connected to the first powered communication port one 58 (1) (square frame 238), so controller 176 determines whether the first powered communication port one 58 (1) is disconnected connection (square frame 249).If not, so controller 176 determines whether PD156 (2) is connected to the second powered communication port one 58 (2) (square frame 250).If so, so controller 176 obtains the grade (square frame 252) of the PD156 (2) being connected to powered communication port one 58 (2) from PSE170.Controller 176 determines whether can obtain power budget is enough to the PD156 being in self class rating (2) power supply (square frame 254).If so, so controller 176 guides PSE170 to enable powered communication port one 58 (2), to provide electric power (square frame 256) to the PD156 (2) being connected to powered communication port one 58 (2).The RAU14 that controller 176 comes in more new memory 178 based on the grade of the PD156 (2) being connected to powered communication port one 58 (2) can obtain power budget (square frame 246), thus avoids when not remaining enough power budget electric power being guided to another powered communication port one 58 (1).If can obtain power budget be not enough to be connected to powered communication port one 58 (2) PD156 (2) power supply (square frame 254), so controller 176 is stopped using powered communication port one 58 (2), thus avoids PSE170 electric power to be supplied to powered communication port one 58 (2) (square frame 258).
