Description

Method and device for setting parameters of user equipment according to available energy

technical field

The invention relates to a method and a device for setting the working parameters of user equipment according to the available energy of the user equipment. Specifically, the present invention relates to a method and a device for enabling user equipment with lower available energy to further save energy and prolong standby and service time by changing parameter settings of user equipment based on the available energy of the user equipment.

Background technique

With the development of communication technology in the direction of mobility and broadband, the energy saving of mobile terminals has been widely concerned. Many communication standardization organizations have added energy-saving considerations when formulating relevant standards. In particular, the access network of the future mobile communication system will be based on IP technology for data transmission, and the burst characteristics of IP data packets and the sharing characteristics of transmission channels among users make the data arriving at user equipment discontinuous. Therefore, how to It is more important to save energy consumption of user equipment (UE).

The 3rd Generation Partnership Project ( ^3rd Generation Partnership Project, 3GPP), as an important organization in the field of mobile communication, has greatly promoted the standardization progress of the 3rd generation mobile communication technology (The Third Generation, 3G), and formulated a series of Communication system specifications including Wide Code Division Multiple Access (WCDMA), High Speed Downlink Packet Access (HSDPA), High Speed Uplink Packet Access (HSUPA), etc. . In order to meet the challenges of broadband access technology and to meet the growing demand for new services, 3GPP started the standardization of 3G Long Term Evolution (LTE) technology at the end of 2004, hoping to further improve spectrum efficiency and improve cell edge user performance, reduce system delay, and provide higher-speed access services for high-speed mobile users.

In the mobile communication system, because the interaction of information between the user equipment and the base station is based on the energy supply of both parties, and for most battery-powered mobile terminals such as mobile phones, notebook computers, and personal digital assistants (PDAs), their Energy reserves are limited. In addition, since different UEs enter the network at different times, their remaining available energy will also vary. Under the same network conditions, UEs with lower available energy will be forced to shut down earlier than UEs with more available energy, so that they cannot continue to be served by the network. From the user's point of view, users with low available energy hope to further save their power consumption, thereby prolonging their standby time until they can meet the charging conditions. Therefore, it is necessary to consider the difference in remaining available energy of UEs, and perform operations on UEs with low available energy different from UEs with sufficient energy, so as to improve the situation of network service interruption caused by insufficient energy.

In order to reduce energy consumption and prolong UE standby and service time, the 3GPP standard adopts the Discontinuous Reception (DRX) mode, which allows the UE to monitor the channel and receive downlink services within a specific period of time agreed with the base station, It can reduce the time of unnecessary channel monitoring and reduce the energy consumption of the UE. This DRX mode is also adopted by LTE, and can be applied in both radio resource control idle (RRC_IDLE) and radio resource control connected (RRC_CONNECTED) states. For example, in the RRC_IDLE state, the user periodically monitors a paging channel (PCH, Paging CHannel) at predetermined intervals. The network also only broadcasts information for that UE at these specific paging occasions. After receiving the paging information destined to itself, the UE wakes up and prepares to access the network and establish a connection. If the UE does not receive paging information destined for itself, it enters a sleep period to save energy.

Through this kind of discontinuous reception, the UE can reduce the time of monitoring the channel, thereby saving energy and prolonging the standby and service time. However, if the paging information directed to a certain UE arrives during the sleep period of the UE, the network will not be able to send the paging information to the UE until the next paging moment of the UE, thus causing the paging information to be lost. Delay. Therefore, the sleep time in the discontinuous reception mode and the delay of paging information are two aspects that affect each other, and a compromise should be made between the two. Considering that the remaining available energy of UEs is different, a longer sleep time may be set for UEs with lower remaining energy. Although this will increase the delay of the paging information, the UE thus saves energy, thereby achieving the purpose of extending standby and service time.

On the other hand, before the UE enters the network to use the corresponding service, it needs to register its location information in a registration area. Within a tracking area (Tracking Area, TA), the UE can roam without performing location registration operations. The coverage of the tracking area is a compromise between the amount of system information and the number of location registrations. The larger the tracking area, the UE can move within a larger range without the need for location registration, thereby reducing energy consumption; and the larger tracking area consists of a larger number of cells, so the system needs to report to the UE in these cells UEs broadcast information such as paging messages. That is to say, the paging message directed to the UE will occupy radio resources of multiple cells. Therefore, for a UE with low remaining energy, it can be considered to register with multiple tracking areas, so as to expand the range of the user being tracked, reduce the energy consumption caused by the most location registration times, and prolong the standby and service time.

Detailed ways

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings, and unnecessary details and functions for the present invention will be omitted during the description to prevent confusion in the understanding of the present invention.

In wireless communication systems, most user equipment powered by batteries, such as mobile phones, notebook computers, and personal digital assistants (PDAs), have limited energy reserves. For the user, when the available energy is low, the user usually hopes to further save its power consumption, thereby prolonging its standby and service time. In this case, although the delay of the paging information is caused arbitrarily, it is better than being forced to interrupt the network service due to insufficient power. Therefore, there is a need for a method that can prolong the standby and service time of the UE as much as possible, so that the user can have time to find charging conditions. The present invention has been made to achieve the above objects.

FIG. 1 is a configuration diagram showing a device for setting UE operating parameters based on the available power of the UE to prolong the standby and service time of the UE according to an embodiment of the present invention. According to this embodiment, as shown in FIG. 1, a user equipment (UE) energy matching unit 11, a parameter adjustment and indication unit 12, and a transmitting/receiving unit 13 are configured on the network side (eNB: base station), and the user equipment (UE) The UE) side is configured with a transmitting/receiving unit 14, an available energy detecting unit 15, and a parameter adjusting unit 16.

On the UE side, the available energy detection unit 15 is used to detect the available energy of the UE, and send the detection result to the base station through the transmitting/receiving unit 14 (which can be used as the first transmitting/receiving unit). It should be noted that the available energy detection unit 15 may select an interval for detecting available energy according to a predetermined interval specified by the base station, or according to its own remaining energy level. Alternatively, the available energy detection unit 15 may extend the interval at which it detects available energy as the available energy decreases, so as to further reduce energy consumption. The parameter adjustment unit 16 changes corresponding operating parameters of the UE according to the detection result transmitted from the transmitting/receiving unit 14, thereby changing the operation of the UE. As an example, the parameter adjustment unit 16 can further reduce the energy consumption of the UE by prolonging the sleep time of the UE, shortening the activation period, increasing the paging cycle, increasing the measurement interval, and reducing the number of registration times of the UE. The transmitting/receiving unit 14 transmits and/or receives various information to and/or from the base station side through a wireless interface. Here, the measurement interval is the interval for measuring inter-frequency cells and cells of different radio access technologies.

On the base station side, the user energy matching unit 11 receives available energy information from the UE, and matches the information to corresponding parameters according to the relationship established on the base station side and corresponding to the UE available energy information. The parameter adjustment and indication unit 12 adjusts the parameters corresponding to the available energy of the UE according to the matching result of the user energy matching unit 11, that is, various parameters matched with the available energy information, and transmits the parameters through the transmitting/receiving unit 13 ( can be sent to the UE as the second transmitting/receiving unit), and the base station can support parameter configuration according to the available energy of the user equipment or send information allowing the user equipment to report its available energy when needed. The transmitting/receiving unit 13 transmits and/or receives various information to and/or from the UE side through a wireless interface.

Fig. 2 shows a flow chart of setting UE operating parameters based on the available power of the UE at the UE side according to an embodiment of the present invention. The operation on the UE side is described below with reference to FIG. 2 . On the UE side, the available energy detection unit 15 included in the UE detects the current available energy of the UE (step S201). If the UE is powered by a power source, for example, when charging user equipment such as mobile phones, laptops, PDAs, etc., it can be assumed that the current available energy of the UE is infinite. However, when the battery is used to supply power to the UE, the current available energy of the UE is the remaining energy of the battery. As an example, the current available energy of the UE may be represented by the ratio of the remaining energy of the battery to the total energy of the battery, or the current available energy of the UE may be represented by the available time of the battery, where the available time may be represented by the standby time.

Generally, the current mobile terminals can display the remaining power of the battery on the display screen. For example, one-third of the battery power is available on the display. In order to reduce the overhead occupied by the UE in reporting its remaining energy to the base station, the energy of the UE can be classified so that the UE only reports its current level.

Figure 3a shows an example of direct representation of available energy, which can be graded by the ratio of available energy to total energy. As an example, the available energy can be divided into four levels, and the level of the available energy is indicated by the ratio of the available energy to the total battery capacity. For example, when the available energy is the total capacity of the battery, when the ratio of the available energy to the total capacity of the battery is 1, it can be represented by two bits "00"; when the available energy is 3/4 of the total capacity of the battery, it can be represented by Bit "01" indicates that the available energy is 3/4 of the total battery capacity; when the available energy is 1/2 of the total battery capacity, bit "10" can be used to indicate that the available energy is 1/2 of the total battery capacity; When the available energy drops to 1/4 of the total capacity, the bit "01" is used to indicate that the available energy is 1/4 of the total capacity of the battery. It should be pointed out that the energy classification of the present invention is not limited to four levels, but the available energy can be divided according to the specific use situation or environment. Correspondingly, different bits can be used to represent the ratio of the available energy to the total battery capacity. In addition, the available standby time of the battery can also be used to represent the available energy of the user's battery. For example, if the available battery standby time is greater than one hour, it is the first level, and if the battery's available standby time is within half an hour or less than one hour, it is the second level. , within half an hour is level 3, and so on. Here, the threshold value of the standby time used for grading can be set by the network.

Returning to FIG. 2, in step S202, after detecting the level of available energy, the UE further detects whether the available energy has changed by an available energy level. If it is determined in step S202 that the available energy has not changed by one level, the flow returns to step S201, and the UE continues to detect its available energy at predetermined intervals. If it is determined in step S202 that the available energy has changed by one level, the UE sends the detection result, that is, the current level of available energy, to the base station through the transmitting/receiving unit 14 (step S203). Next, in step S204, after the UE sends the new detection result to the base station, the UE detects whether a new parameter configuration corresponding to the new detection result is received from the base station through the transmitting/receiving unit 14 . Here, the corresponding parameter may be a new paging cycle, or information about allowing multiple TAs to be accessed (details will be described later). If the UE determines in step S204 that no new parameter setting has been received from the base station, the UE does not change its own parameter setting, and returns to step S201 to continue operating based on the original parameter device. If the UE determines in step S204 that a new parameter setting has been received from the base station, then the UE changes its operation according to the newly received parameter setting in step S205. Afterwards, continue to detect its available energy according to the new parameter settings.

In step 203 where the UE sends the detection result of the current available energy to the base station, in order to further reduce the overhead of indicating the detection result, 1 bit may be used to represent the change of the UE's available energy instead of directly representing the available energy. As shown in Figure 3b, 1 bit can be used to represent the change of the energy level. It may be assumed that the energy of the UE is divided into N levels, and the level of 1 indicates that the available energy is the total available energy of the battery or is powered by a power supply. Every time the level is increased by one level, the energy is reduced by a part, and the level is N, which means that the energy of the UE is about to be consumed. In this case, this bit can be set to 1 every time the available energy of the UE drops by one level. Conversely, if the UE is being charged, the bit can be set to 0 when the available energy of the UE is continuously increasing, indicating that the available energy of the user returns to the maximum value, and vice versa. That is to say, whenever the available energy of the UE drops by one level, the UE sends indication information with a bit of "1" to the base station, and whenever the available energy of the UE rises by one level, the UE sends an indication information with a bit of "0" to the base station. Instructions. In this way, the base station can reduce or increase the available energy of the UE by one level according to the available energy level of the UE stored in the base station based on the change indication information of the available energy received from the UE, thereby judging that the UE is currently in available energy level. Similarly, in order to reduce energy consumption, the UE may send an indication that the available energy decreases or increases to the base station when the available energy decreases or increases by one level.

Fig. 4 shows a flow chart of setting UE operating parameters by a base station (eNB) based on available power of the UE according to an embodiment of the present invention. As shown in Fig. 4, at step S401, the base station receives information from the UE, and at step S402 detects whether information related to the available energy of the UE is received. The information related to the available energy of the UE may be the available energy level as shown in Figure 3a, or the change of the available energy level as shown in Figure 3b. If the base station judges in step S402 that no information related to the available energy of the UE has been received, the process returns to step S401 and continues to receive information from the UE. If the base station determines in step S402 that information related to the available energy of the UE has been received, the process proceeds to step S403, where the base station determines the operating parameters of the UE that need to be updated according to the current available energy of the UE. Thereafter, in step S404, the base station adjusts the operating parameters of the UE according to the determination result of step S403, and sends the new operating parameters to the UE through the transmitting/receiving unit 13. Thereafter, the base station returns to step S401 to continue receiving user information.

In the above step S403, the parameters determined by the base station may include a paging cycle, a measurement interval, or the number of TA registrations. In order to realize parameter reconfiguration, the base station side needs to match between the received UE available energy level and the parameter change factor. Fig. 5 shows a schematic diagram of an example in which the base station matches the available energy of the UE with the parameter change factor. The following describes the matching relationship between available energy and parameter conversion factors with reference to FIG. 5 .

For each available energy level i, there is a parameter change factor ki corresponding to level i at the base station side. The energy may be the maximum available energy, that is, the parameter variation factor when the available energy level is 1 may be set to 1. If the currently updated parameter is the paging cycle for the UE, it may be assumed that the paging cycle of the system is Tp. In consideration of the available energy of the UE, the paging cycle of the UE whose available energy level is i can be set as Tp/ki. As an example, ki=1-i/N (where i≦N, N is a natural number) can be set. In this case, as the available energy of the UE decreases, the level i of the available energy will increase accordingly, and the parameter change factor ki=1-i/N will gradually increase. Therefore, the paging cycle Tp/ki of the UE will continue to increase. In this way, the UE's energy consumption is further reduced by prolonging its sleep time.

Similarly, if the updated parameter is the measurement interval, the above setting method can also be used to configure a longer measurement interval for UEs with lower available energy, so as to reduce the number of times the UE wakes up to perform measurements. It should be pointed out that the present invention is not limited to the update parameters given in the above example, but any parameter that can reduce the energy consumption of the UE can be updated according to the idea of the present invention.

For example, if the updated parameter is the number of TAs that the UE is registered in, then the parameter change factor ki can be set to i when matching, indicating the number of TAs that the UE can register with. For example, when the available energy of the UE is the i-th level, i TAs can be registered at the same time. In this case, by broadcasting the information of the UE in multiple TAs, it is avoided that the UE frequently sends registration information to update its location information during the roaming process, thereby reducing the energy consumption of the UE. For this parameter, since the base station is responsible for registering the location information and determining the number of TAs that the UE can register, there is no need for the base station to notify the UE of the updated parameters, so step S404 in FIG. 4 can be omitted. The base station may change the tracking area registration number of the user equipment according to Tp×ki. Here, Tp represents the number of registered TAs.

Fig. 6 shows a flowchart of information exchange between a base station and a UE for changing the paging cycle of the UE according to an embodiment of the present invention. Taking the information exchange in LTE as an example, the base station may instruct the UE to report its current available energy level information in a System Information or Tracking Area Update message. After the UE receives the information indicating that it should report the available energy level, it will report its available energy level when its available energy level changes (as shown in Figure 3a) or report the change of the available energy level (as shown in Figure 3b Show). These report information can be included in the measurement report and sent to the base station. After receiving the information of available energy from the user, the base station calculates new working parameters for the UE according to the matching result of its own available energy information and the parameter change factor. As shown in FIG. 6, the UE calculates the paging cycle, and sends the updated paging cycle to the sending UE through an RRC reconfiguration (RCC RECONFIGURATION) message. It can be understood that the present invention is not limited thereto, and other parameters capable of reducing energy consumption may also be calculated for the UE.

In addition, the energy consumption of the UE can also be reduced by changing the number of TAs registered by the UE. Fig. 7 shows a flow chart of information exchange between a base station and a UE for changing the number of TAs registered by the UE according to an embodiment of the present invention. Still taking the information exchange in LTE as an example, when the UE detects a change in its available energy, the UE can report its available energy level to the base station in a TA update message. The UE may report its available energy level or change of available energy to the base station in the manner shown in FIG. 3a or 3b. After receiving the available energy information from the UE, the base station judges how many TAs the UE will register with according to the available energy level of the UE, and registers the UE with the corresponding TAs. It should be noted that, in order to save energy consumption of the UE, the UE may also report its available energy level or change of the available energy to the base station when its available energy drops or rises to a predetermined threshold. The base station judges how many TAs the UE will register with according to the available energy level of the UE, and registers the UE with the corresponding TAs.

The present invention sets the operating parameters of the UE according to the available energy of the UE, so that the UE with low available energy can further reduce the energy consumption by prolonging the sleep time and reducing the location registration, so as to further extend the life of the user, especially the user with low available energy. standby and service time.

So far the invention has been described with reference to the preferred embodiments. It should be understood by those skilled in the art that various other changes, substitutions and additions can be made without departing from the spirit and scope of the present invention. Accordingly, the scope of the present invention should not be construed as limited to the particular embodiments described above, but should be defined by the appended claims.
