Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to an energy-saving method, device and electronic equipment for an indoor distribution system. Background Technology

[0002] The testing of the fifth-generation mobile communication system adopted Massive MIMO technology and a high-bandwidth approach, which significantly improved power consumption compared to the fourth-generation mobile information system. For the indoor distribution system of the fifth-generation mobile communication, a 4-antenna miniature radio remote unit (pRRU) was adopted, and the cell bandwidth can reach 100MHz. Therefore, energy saving and power consumption reduction of the indoor distribution system is very necessary.

[0003] Among related technologies, one approach is to adopt the same energy-saving schemes as outdoor macro base stations, such as reducing the number of coverage layers, reducing the number of data transmission antenna channels, and reducing transmission time to shut down transmission channels under multi-carrier conditions. This method is applicable to various scenarios, but its energy-saving effect is limited. Another approach is to configure fixed times for turning base stations on or off in locations with significant tidal effects to achieve energy savings. While this method is effective, the configured times cannot be well adapted to user behavior, leading to network unavailability for users in certain situations and impacting user experience. Therefore, how to accurately and efficiently save energy in indoor distributed systems has become an urgent problem to be solved. Summary of the Invention

[0045] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of this application, including various details to aid understanding. These should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this application. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0046] The following examples illustrate the energy-saving method, apparatus, and electronic equipment of the indoor distribution system of this application.

[0047] Figure 1 This is a flowchart illustrating an energy-saving method for an indoor distributed antenna system (DAS) according to an embodiment of this application. It should be noted that the executing entity of the energy-saving method in this embodiment is the energy-saving device of the DAS, which can specifically be a hardware device or software within a hardware device. The hardware device can be, for example, a terminal device or a server.

[0048] like Figure 1 As shown, the energy-saving method for an indoor distribution system proposed in this embodiment includes the following steps:

[0049] S101, detect whether there is no service transmission under any channel in the target cell during the first target time period, wherein any channel corresponds to at least one type I micro radio remote unit pRRU.

[0050] It should be noted that the base station can detect whether there is no service transmission under any channel in the target cell during the first target time period.

[0051] Among them, a base station refers to a public mobile communication base station, which is an interface device for mobile devices to access the Internet. It is also a form of radio station, which refers to a radio transceiver station that transmits information between a mobile communication switching center and a mobile phone terminal within a certain radio coverage area.

[0052] In the embodiments of this application, any channel can correspond to one Type I micro radio remote unit pRRU, or it can correspond to a channel formed by merging multiple Type I micro radio remote units pRRU.

[0053] It should be noted that this application does not impose any restrictions on the setting of the first target time period, which can be selected according to the actual situation.

[0054] S102, if it is determined that there is no service transmission under any channel in the target cell during the first target time period, then all Type I pRRUs corresponding to any channel are turned off.

[0055] It should be noted that when there is no service transmission in the first target segment under any channel in the target cell, the target cell can enter the first-level energy-saving state by shutting down all the first-class pRRUs corresponding to any channel.

[0056] For example, after shutting down all Type 1 pRRUs corresponding to any channel, such as Figure 2 The diagram shows a schematic of the indoor distribution system in the target community when it enters energy-saving mode.

[0057] S103, continue to detect whether there is a user equipment (UE) accessing the target area within the target cell, wherein at least one type II pRRU is set in the target area.

[0058] In this embodiment of the application, at least one second type pRRU is set in the target area, and the second type pRRU is in a normally open state (lighthouse location). The second type pRRU can send system information of the target cell, thereby detecting whether there is a user equipment (UE) accessing the target area within the target cell.

[0059] S104 If it is determined that no UE enters the target area within the target cell, then all Type II pRRUs are turned off.

[0060] It should be noted that since user behavior in most locations is not completely fixed, related technologies often set fixed times to turn base stations on or off. However, due to the great uncertainty of user behavior, if a user arrives at the location before the set time to turn on or leaves after the set time to turn off, there will be no network available. At the same time, if a user leaves early and does not turn off the equipment in time, it will also result in a waste of resources.

[0061] This application proposes an energy-saving method for indoor distribution systems. Through reasonable planning and deployment, users can be detected in a timely manner and the miniature radio frequency remote unit (pRRU) in energy-saving state can be activated, thereby improving the user's perception ability and thus improving the energy-saving effect.

[0062] It should be noted that, in order to improve the energy-saving effect of the target cell, when it is determined that no UE enters the target area within the target cell, all Type II pRRUs can be turned off, thereby enabling the cell to enter the Level 2 energy-saving state.

[0063] Furthermore, such as Figure 3 As shown, in order to detect when a user enters the cell and promptly activate other pRRUs in energy-saving mode, pRRUs (guard posts) can be set up in the target area within the target cell to detect the UE's camping information and promptly activate the pRRUs at the energy-saving lighthouse posts. Then, the pRRUs at the lighthouse posts can promptly activate other pRRUs in energy-saving mode based on the UE's access information. At this point, the system enters normal service mode.

[0064] It should be noted that when entering the Level 2 energy-saving state, the Type 2 pRRUs that are normally open (lighthouse locations) are turned off, while the pRRUs at guard booth locations remain open and update the base station's system information.

[0065] The energy-saving method for indoor distributed antenna systems (DAS) proposed in this application detects whether there is no service transmission under any channel in the target cell during a first target time period. Each channel corresponds to at least one Type I micro remote radio unit (pRRU). If no service transmission is detected under any channel in the target cell during the first target time period, all Type I pRRUs corresponding to that channel are turned off. The method then continues to detect whether there is user equipment (UE) accessing the target area within the target cell. At least one Type II pRRU is installed in the target area. If no UE enters the target area within the target cell, all Type II pRRUs are turned off. Through reasonable planning and deployment, this application can promptly detect users and wake up energy-saving pRRUs, improving user awareness and enabling more precise time-based control of energy saving in the indoor DAS, thus improving the energy-saving effect of the indoor DAS.

[0066] It should be noted that, in this application, in order to reduce the power consumption of the indoor distributed antenna system, the target MIB and target SIB1 can be broadcast after the indoor distributed antenna system enters the energy-saving state.

[0067] As one possible way to achieve this, such as Figure 4 As shown, based on the above embodiment, the specific process after shutting down all Type 1 pRRUs corresponding to any channel includes the following steps:

[0068] S401, modify the broadcast status of system information SI in system information block SIB1 to not broadcast, so as to obtain target SIB1.

[0069] Among them, the System Information Block (SIB) can define the scheduling of other SIBs and contain the information required for initial access.

[0070] It should be noted that, in order to reduce power consumption, the broadcast status of the system information SI in the system information block SIB1 can be modified to not broadcast, so as to obtain the target SIB1.

[0071] S402, acquire the target master information block (MIB) and broadcast the target MIB and target SIB1.

[0072] The Master Indication Block (MIB) can broadcast cell information status to the UE.

[0073] In this embodiment of the application, after obtaining the target master information block MIB, the target MIB and target SIB1 can be broadcast, that is, the target MIB and target SIB1 can be broadcast in the manner of on-demand broadcasting of SI.

[0074] Optionally, the target MIB and target SIB1 can be broadcast based on the protocol SIB1->si-SchedulingInfo->schedulingInfoList->si-BroadcastStatus=notBroadcasting.

[0075] It should be noted that after the target cell enters the energy-saving state, the system information of the target SIB1 of the target cell can be configured. For example, the scheduling information of each system information SI can be configured, that is, the schedulingInfo can be configured. The length of the schedulingInfo array can also be configured, that is, the schedulingInfoList can be configured. The si-broadcaststatus can also be configured. Finally, the si-broadcaststatus can be configured to notBroadcasting, that is, on-demand broadcasting.

[0076] Furthermore, in order to improve the coverage distance of the target cell, the current transmission power of the SI can be obtained and adjusted to the target transmission power.

[0077] It should be noted that, for the UE side, when a UE enters the coverage area of ​​the guard post, it can read system information to prepare to camp on the cell. The UE can determine whether the si-Broadcast for other SIBs in SIB1 is Statusbroadcasting or notBroadcasting. If it is broadcasting (broadcasting SI), it will continue to read other SIB information; otherwise, it will trigger the (on demand SI) process.

[0078] It should be noted that, in order to reduce the power consumption of the indoor distributed antenna system, the target MIB and target SIB1 can be broadcast after the indoor distributed antenna system enters the energy-saving state.

[0079] As one possible way to achieve this, such as Figure 5 As shown, based on the above embodiment, the specific process after shutting down all Type 1 pRRUs corresponding to any channel includes the following steps:

[0080] S501. Assign the tracking area code information in SIB1 to the target value to obtain the target SIB1.

[0081] It should be noted that when the target community is in the second-level energy-saving state, only the pRRU at the guard post is in the open state. The tracking area code information in SIB1 can be assigned to the target value, thereby obtaining the target SIB1.

[0082] That is: SIB1->cellAccessRelatedInfo->plmn-IdentityList->trackingAreaCode = a special value, and configure the target cell access-related information, i.e., cellAccessRelatedInfo, based on the protocol, and configure the identifier of the public land mobile network plmn and the list of additional information associated with plmn, i.e., plmn-IdentityList, and assign a special value, i.e., the target value, to the tracking area code information, i.e., trackingAreaCode, in SIB1, so that the target SIB1 can be obtained.

[0083] Optionally, trackingAreaCode is a special value that the operator does not currently plan to use. For example, TrackingAreaCode = 0xFFFFFF, and using 0xFFFFFF as a special value is the target value.

[0084] S502. Obtain the target MIB and broadcast the target MIB and target SIB1.

[0085] In this embodiment of the application, after obtaining the target MIB and the target SIB1, the target MIB and the target SIB1 can be broadcast based on the Mobility Registration Update method.

[0086] Furthermore, in order to improve the coverage distance of the target cell, the current transmission power of the SI can be obtained and adjusted to the target transmission power.

[0087] It should be noted that, for the UE side, when a UE enters the coverage area of ​​the guard post, it can read the system information to prepare to camp in the cell, and can read the trackingAreaCode in SIB1 to initiate the Mobility Registration Update process.

[0088] In this embodiment of the application, after all Type II pRRUs are turned off, if a UE is found to enter the target area, then the Type II pRRUs need to be turned on.

[0089] As one possible way to achieve this, such as Figure 6 As shown, based on the above embodiment, the specific process after shutting down all Type II pRRUs includes the following steps:

[0090] S601. Receive random access information sent by the UE and broadcast other SIs, wherein the other SIs do not include either MIB or SIB1.

[0091] Among them, random access information can be signaling information during the UE's random access process.

[0092] As one possible implementation method, the base station can receive random access information sent by the UE via MSG3.

[0093] It should be noted that other SIs refer to SIs other than the target MIB and target SIB1. For example, other SIs can be IB2, SIB3, SIB4, etc.

[0094] In this embodiment of the application, the SI broadcast state in the target SIB1 can be restored to broadcasting.

[0095] S602. If it is determined that a UE has entered the target area, then all Type II pRRUs will be activated.

[0096] In this embodiment of the application, if a UE is found to have entered the target area, all second-type pRRUs are activated, which can promptly detect the entry of a UE into the target area and activate all second-type pRRUs in power-saving mode.

[0097] It should be noted that before enabling the second type of pRRU, after receiving the random access information sent by the UE, the radio resource control establishment request can be extracted from the random access information, and the UE access can be rejected.

[0098] As one possible way to achieve this, such as Figure 7 As shown, based on the above embodiments, the specific process before activating the second type of pRRU includes the following steps:

[0099] S701, Receive random access information sent by the UE.

[0100] Among them, random access information can be signaling information during the UE's random access process.

[0101] As one possible approach, the base station can receive random access information sent by the UE.

[0102] S702: Extract the Radio Resource Control Establishment Request from the random access information and reject the UE's access.

[0103] In this embodiment of the application, the radio resource control establishment request can be extracted from the random access information sent by the UE. When the energy saving status of the target cell is the second energy saving status, that is, the second type of pRRU in the normally open state (lighthouse location) is closed, and the pRRU in the guard post location remains open. Then the UE access can be rejected, the broadcast information of the target cell system can be restored, and the tracking area code information in the target SIB1 can be restored to the initial value.

[0104] SIB1->cellAccessRelatedInfo->plmn-IdentityList->trackingAreaCode=Normal value.

[0105] Furthermore, after the second type of pRRU is activated, the uplink transmission channels of all first type of pRRUs can be activated, and the target cell returns to the first-level energy-saving state. After activating the uplink transmission channels of all first type of pRRUs, if it is confirmed that the service transmission access information sent by the UE has been received, the downlink transmission channels of all first type of pRRUs will be activated, and the target cell will provide normal service and return to the normal service state.

[0106] The energy-saving method for the indoor distribution system proposed in this application will be explained below.

[0107] For example, such as Figure 8 As shown, when the target cell is in the second-level energy-saving state, i.e. the dormant state, when the UE enters the cell coverage area, it can read the information of the indoor distribution system. At this time, the UE triggers the process of reading other SIs or updating the UE's location information (Tracking Area Updating, abbreviated as TAU). After the target cell captures the UE's access information, it activates the second type of pRRU and opens the uplink transmission channel of other points to update the information of the indoor distribution system.

[0108] In summary, the energy-saving method for indoor distributed antenna systems (DAS) proposed in this application, by planning and deploying the DAS, can divide the DAS into two energy-saving states, making the energy saving of the DAS more precise in terms of time control and achieving better energy-saving effects. Simultaneously, it can promptly detect UE (User Equipment) camping information and trigger the wake-up of pRRUs in energy-saving states. That is, without affecting user experience, the terminal sends information to the network, enabling the network to detect user camping and thus triggering the network to activate the pRRU, thereby improving the energy-saving effect of the DAS.

[0109] To achieve the above embodiments, this embodiment provides an energy-saving device for an indoor distribution system. Figure 9 This is a schematic diagram of the structure of an energy-saving device for an indoor distribution system provided in an embodiment of this application.

[0110] like Figure 9 As shown, the energy-saving device 1000 of the indoor distribution system includes: a first detection module 110, a first shutdown module 120, a second detection module 130, and a second shutdown module 140. Among them,

[0111] The first detection module 110 is used to detect whether there is no service transmission under any channel in the target cell during the first target time period, wherein the any channel corresponds to at least one type of miniature radio frequency remote unit pRRU.

[0112] The first shutdown module 120 is used to determine that there is no service transmission under any channel in the target cell during the first target time period, and then shut down all the first type of pRRUs corresponding to any channel.

[0113] The second detection module 130 is used to continue detecting whether there is a user equipment (UE) accessing the target area within the target cell, wherein at least one type II pRRU is set in the target area;

[0114] The second shutdown module 140 is used to determine that no UE enters the target area within the target cell, and then shut down all the second type of pRRU.

[0115] According to one embodiment of this application, the first closing module 120 is further configured to: modify the broadcast status of the system information SI in the system information block SIB1 to not broadcast, so as to obtain the target SIB1; obtain the target master information block MIB, and broadcast the target MIB and the target SIB1.

[0116] According to one embodiment of this application, the first closing module 120 is further configured to: assign the tracking region code information in SIB1 to a target value to obtain target SIB1; obtain target MIB, and broadcast the target MIB and target SIB1.

[0117] According to one embodiment of this application, the apparatus 1000 is further configured to: obtain the current transmission power of the SI, and adjust the current transmission power to a target transmission power.
