Method used

[0071] In the second embodiment, the home base station determines whether to enter the sleep mode by receiving the sleep command notified by other base stations and combining with the detection of its own business load, so that the home base station can turn off the radio frequency module in time without business demand , enter the sleep mode, thereby further reducing the energy consumption of the home base station, and preventing the home base station from causing unnecessary interference to surrounding users.

[0103] In addition, the base station determines whether to enter the sleep mode by receiving the sleep command notified by other base stations and in combination with the detection of its own business load, so that the base station can turn off the radio frequency module in time when there is no business demand, and enter the sleep mode, thereby The energy consumption of the base station is further reduced, and unnecessary interference to surrounding users by the base station is avoided.

[0109] In this embodiment, the second base station sends a sleep/wake command to the base station before the handover and the base stations in the calculated base station set after the UE is handed over, so as to wake up the base station to which the UE may be handed over, so that the UE can smoothly recover from all base stations. The base station is handed over to other serving base stations. On the basis of saving energy consumption, it does not affect the normal operation of the home base station, thereby ensuring user experience.

Abstract

The invention discloses a base station control method and a system thereof, and apparatuses. The base station control method comprises: a first HeNB detects whether there is UE in service in a first preset period; and when there is no UE in service, the first HeNB enters a sleep mode. According to the base station control method and the system thereof, and the apparatuses, a base station automatically enters a sleep mode according to a service load of the base station itself under the circumstances that there is no service demand in a cell; therefore, energy consumption of the base station is reduced and meanwhile, it is avoided that the base station generates unnecessary interferences on surrounding users. In addition, before there is a service demand, the base station can be restarted or woken up timely; on the basis that energy consumption is saved, normal working of the HeNB is not influenced, so that using perception of the user can be ensured.

Example

[0066] Such as figure 1 As shown, the second embodiment of the base station control method of the present invention includes the following steps:

[0067] Step 102: When the UE leaves HeNB1 to the new base station new BTS, the new BTS sends a sleep command to HeNB1;

[0068] Step 104: After the HeNB1 receives the sleep command, it detects whether there is a serving UE within the first preset time period.

[0069] Step 106: When there is no serving UE, turn off its own radio frequency module, and HeNB1 enters sleep mode;

[0070] Step 108: When there is a serving UE, HeNB1 works normally.

[0071] In the second embodiment, the home base station determines whether to enter sleep mode by receiving sleep commands notified by other base stations and combining with the detection of its own business load, so that the home base station can turn off the radio frequency module in time and enter sleep mode when there is no business demand. Mode, thereby further reducing the energy consumption of the home base station and avoiding unnecessary interference of the home base station to surrounding users.

Example

[0072] Such as figure 2 As shown, the third embodiment of the base station control method of the present invention includes the following steps:

[0073] Step 202: When the UE performs a cell handover, the UE sends a first list CPlist containing cell identities of all its base stations to the new BTS, and the CPlist contains PCIs of all base stations of HeNB1;

[0074] Step 204: After the UE switches from HeNB 1 to the new BTS, the new BTS compares the second list Nlist and CPlist containing its own neighbor cells, and determines the intersection of the CPlist and Nlist except for the first base station. NCSGlist,

[0075] Mark [(CPlist∩Nlist)-HeNB1]=NCSGlist;

[0076] Step 206: The new BTS sends a sleep command to HeNB1, and HeNB1 judges according to step 104 in the second embodiment of the above method to determine whether to enter a sleep state;

[0077] Step 208: When NCSGlist≠0, new BTS sends a wake-up command to all base stations in NCSGlist. For example, HeNB2 is a home base station in NCSGlist, and new BTS sends a wake-up command to HeNB2;

[0078] Step 210: After receiving the wake-up command, the base station in the NCSGlist enters the wake-up mode.

[0079] In the third embodiment, the subsequent UE handover is further considered, and the base station to which the UE may be handed over is awakened, so that the UE can smoothly handover from the base station where it is located to other serving base stations. On the basis of saving energy, it does not affect the normal operation of the home base station, thereby ensuring the user experience.

[0080] Further, considering that the UE may not switch to another base station immediately, the UE does not switch to the base station in the NCSGlist within the second preset certain time period T after the base station in the NCSGlist is awakened, and the base station in the NCSGlist detects it If there are no serving UEs, these base stations enter the sleep mode again. If the UE does not switch to HeNB1, the base station in HeNB1 detects UEs that are not served therein, and HeNB1 also enters sleep mode. In this way, the energy consumption of the home base station is saved on the basis of not affecting the normal operation of the home base station and ensuring the user experience.

[0081] In addition, if the UE stays in the new BTS for a time t longer than the preset time T, the newBTS periodically sends a wake-up command to the home base stations in the HeNB1 and NCSGlist, or the base stations in the HeNB1 and NCSGlist control themselves to periodically enter the wake-up mode.

[0082] In the third embodiment, when the UE leaves the new BTS, the new BTS sends the leaving information of the UE to the base stations in the HeNB1 and the NCSGlist; the base stations in the HeNB1 and the NCSGlist enter the wake-up mode.

Example

[0083] Such as image 3 As shown, the fourth embodiment of the base station control method of the present invention includes the following steps:

[0084] Step 302: When the UE switches to the new BTS, it searches for the cell identity PCI of the new BTS;

[0085] Step 304: Determine whether the cell ID of the new BTS is in the neighbor cell ID list of the base station (HeNB1) to which the UE belongs, if yes, go to step 306; otherwise, go to step 308;

[0086] Step 306: The UE controls the new BTS to send a wake-up command to HeNB1;

[0087] Step 308, end;

[0088] Step 310: After the HeNB1 receives the wake-up command, it enters the wake-up mode.

[0089] Preferably, if the UE does not switch to the HeNB1 within the second preset time period, and there is no UE serving in the HeNB1, the HeNB1 enters the sleep state.

[0090] In addition, when the UE stays in the new BTS for more than the time period, the new BTS periodically sends a wake-up command to the HeNB1, or the HeNB1 controls itself to enter the wake-up mode periodically.

[0091] More preferably, when the UE leaves the second base station, the new BTS sends the leave information of the UE to HeNB1; HeNB1 enters the wake-up mode.

[0092] In the fourth embodiment, considering that the UE may be handed over to the home base station to which it belongs, after the UE undergoes a cell handover, the UE controls the new base station to give priority to waking up the home base station to which the UE belongs, thus saving energy consumption of the home base station. On the basis of this, the quality of service to users is guaranteed, and user experience is improved.
