Method of managing discontinuous reception functions

The present invention relates to a method for a wireless communication system, and more particularly to a method for managing a discontinuous reception function in a wireless communication system.

The Long Term Evolution (LTE) wireless communication system developed by the 3rd Generation Partnership Project (3GPP) is currently considered to provide high data transmission rates, low latency, packet optimization, and A new wireless interface and wireless network architecture that improves system capacity and coverage. In the long-term evolution wireless communication system, the Evolved Universal Terrestrial Radio Access Network (E-UTRAN) includes a plurality of enhanced Node-Bs (eNBs), and a plurality of A mobile station, or user equipment (UE), communicates.

In the LTE system, the UE is configured with a discontinuous reception (DRX) function, which allows the UE to monitor the signaling transmission of a physical downlink control channel (PDCCH) during a specific period to reduce the signaling. Power consumption of the client. It is worth noting that the discontinuous reception function is set by the base station, and the setting of the discontinuous reception function includes a short-term discontinuous reception cycle (Short DRX cycle) and a long-term discontinuous reception cycle (Long DRX). Cycle). In detail, the discontinuous reception cycle includes a waking period and a sleeping period. If the client receives a transport packet during waking, the awake period should be extended to allow the client to receive the next transport packet. In other words, in order to receive subsequent possible transmission packets, the base station configures a discontinuous reception period with a longer awake period to the UE.

Applicant noticed that if the client is assigned a discontinuous reception function setting with a long awake period, the user terminal will not delay the transmission of the received Internet Protocol (IP) packet to the application, and Provides better experience, but this discontinuous reception function setting will result in higher power consumption at the user end. Conversely, if the client is assigned a discontinuous reception function setting with a long sleep period, although the power of the user terminal can be effectively saved, the delay of the instant packet transmission is caused. However, the existing LTE system does not regulate how the base station selects the appropriate length of the awake period/sleep period to set the discontinuous reception function of the user terminal, thus causing the above problem to occur.

Accordingly, the present invention provides a method for managing a discontinuous reception function in a wireless communication system to solve the above problems.

The wireless communication system 10 can be a Long Term Evolution (LTE), a universal mobile telecommunications system (UMTS), or any other similar network system, which is simply a network end and a plurality of network systems. It consists of mobile devices. In the LTE system, the network can be an evolutionary A universal terrestrial global radio access network (evolved-UTRAN, EUTRAN), which may include a plurality of evolved base stations (eNBs) or a core network (eg, a mobility management entity (MME)), and Mobile devices can be considered as user terminals (UEs), such as mobile phones, computer systems, and the like. In addition, according to the transmission direction, the network end and the user end can be regarded as a transmitter and a receiver. For example, for an uplink (UL) transmission, the UE is the transmitter and the network is the receiver; for the downlink (DL) transmission, the network is the transmitter and the client is the client. Receiving end.

Please refer to FIG. 2, which is a schematic diagram of a communication device 20 according to an embodiment of the present invention. The communication device 20 can be the mobile device in FIG. 1 , and includes a processing device 200 , a storage unit 210 , and a communication interface unit 220 . Processing device 200 can be a microprocessor or an application-specific integrated circuit (ASIC). The storage unit 210 can be any data storage device for storing a code 214 and reading and executing the code 214 through the processing device 200. For example, the storage unit 210 can be a subscriber identity module (SIM), a read-only memory (ROM), a random access memory (RAM), a compact disc. CD-ROMs, magnetic tapes, floppy disks, optical data storage devices, and the like are not limited thereto.

Please refer to FIG. 3, which is a flowchart of a process 30 in a wireless communication system for managing a discontinuous reception function to reduce power consumption of a user end. The process 30 can be compiled into the code 214 and includes the following steps: Step 300: Start.

Step 302: When a setting of the user terminal is changed, transmitting information about the setting to a network end of the wireless communication system, so that the network side sets the discontinuous receiving function of the user end according to the information.

Step 304: End.

According to the process 30, when the setting of the client is changed (for example, the power setting/application mode setting/required network response time is changed by the user setting), the client will report the power setting/application mode setting/required about the client. The network responds to the time information to the network, so the network (such as the base station) can use this information to set the length of the awake period/sleep period in the discontinuous reception period of the user.

For example, when the power of the UE is set to a lower power consumption state by the user, the UE transmits low power consumption information to the network. After receiving this information, the network will reduce the time for receiving function in the discontinuous reception function (ie, increase the sleep period or reduce the awake period). In addition, when the power of the UE is set to a higher power consumption state by the user, the UE transmits high power consumption information to the network. After receiving this information, the network will increase the time for receiving function in the discontinuous reception function (ie, reduce sleep period or increase awake period). Therefore, setting change information is available To assist the network to determine the power parameters of the client (such as the above-mentioned network to increase or decrease the sleep period, it will change the power parameter setting of the client), so as to effectively save the user's power without affecting the user experience.

In another embodiment, when the network response time required by the UE is reduced, the UE transmits relevant information to the network; after receiving the information, the network adds the discontinuous reception function to receive the function. Time (ie reduce sleep period or increase awake period). Conversely, when the network response time required by the UE increases, the UE transmits relevant information to the network; after receiving the information, the network reduces the time for receiving the discontinuous reception function (ie, Increase sleep period or reduce waking period). It is worth noting that the user can decide whether to increase the network response time and thus change the power consumption status of the user.

In another embodiment, the user is allowed to change the application mode settings of the client. The application mode setting can be the current usage state of the user, thereby providing the power consumption state of the user terminal to the network end. For example, the client includes a first application mode for indicating a state of the screen being turned on; a second application mode for indicating that the screen is off and a sound is turned on; and a third application mode for indicating that the screen is closed, the sound is turned off, and the sound is turned off. The status of the shutdown. It is worth noting that the application mode of the client is not limited to the above. For example, the first application mode may be a screen on, the second application mode may be a screen off, a sound off and a vibration on, and the third application mode may be a screen off, a sound off, and a vibration off. In detail, when the user terminal changes from a first application mode to a second application mode through user settings, the client transmits information about the application mode change to the network. end. If the power consumption corresponding to the second application mode is greater than the power consumption of the first application mode, after the network receives the information, the time for receiving the discontinuous reception function is increased (ie, the sleep period is reduced or Increase awake period). Conversely, if the power consumption corresponding to the second application mode is smaller than the power consumption of the first application mode, after receiving the information, the network reduces the time for receiving the discontinuous reception function (ie, increases). During sleep or during awake periods).

In addition, the embodiment of the present invention can obtain the network response time required by the user end from the application mode setting of the client. For example, the client includes a first application mode to indicate that the user is using the mobile phone, such as executing a game program or watching a network TV/movie; and a second application mode is used to indicate that the user places the mobile phone in a pocket or a backpack. Medium, and want to know any mobile phone call / SMS / notification; and the third application mode is used to indicate that the user does not need the phone to make a sound or vibration to indicate the incoming call / SMS / notification. Therefore, the network response time corresponding to the third application mode is greater than the network response time corresponding to the second application mode, and the network response time corresponding to the second application mode is greater than the network response time corresponding to the first application mode. . In detail, when the UE changes from a first application mode to a second application mode through user settings, the UE transmits relevant information to the network. It is worth noting that if the network response time corresponding to the second application mode is greater than the network response time of the first application mode, after receiving the information on the network, the receiving function in the discontinuous reception function is reduced. Time (ie increase during sleep or reduce waking period). Conversely, if the network response time corresponding to the second application mode is less than the network response time of the first application mode, after receiving the information on the network, the time for receiving the discontinuous reception function is increased ( Reduce sleep period Between or during the awake period).

Please refer to FIG. 4, which is a flowchart of a process 40 according to an embodiment of the present invention. The process 40 is used in one of the wireless communication systems to manage the discontinuous reception function. The process 40 can be compiled into the code 214 and includes the following steps: Step 400: Start.

Step 402: Receive information about a setting change of the UE from a client of the wireless communication system.

Step 404: Set the discontinuous reception function of the user end according to the information.

The length of the awake period/sleep period in the discontinuous reception period. Therefore, the setting change information can be used to assist the network to determine the power parameters of the client, thereby effectively saving the power of the client without affecting the user experience.

For example, when the network receives the low power consumption information transmitted by the UE, the network reduces the time for receiving the function in the discontinuous reception function (ie, increasing the sleep period or reducing the awake period). On the other hand, when the network receives the high power consumption information transmitted by the UE, the network increases the time during which the receiving function is performed in the discontinuous reception function (ie, during sleep reduction or during waking period). It is worth noting that For the description of transmitting the setting change information to the network on the client side, refer to the above, and details are not described herein again.

In another embodiment, when the network receives information about the decrease of the network response time from the UE, the network increases the time for receiving the discontinuous reception function (ie, reduces the sleep period or increases the awake period). . Conversely, when the network receives information about the increase of the network response time from the UE, the network will reduce the time for receiving function in the discontinuous reception function (ie, increase the sleep period or reduce the awake period).

In another embodiment, when the network receives information about the application mode change from the user end, the information indicates that the user terminal changes from a first application mode to a second application mode, where the second application mode corresponds to The power consumption is greater than the power consumption of the first application mode, and the network increases the time during which the receiving function is performed in the discontinuous reception function (ie, during sleep reduction or during waking periods). Conversely, if the power consumption corresponding to the second application mode is smaller than the power consumption of the first application mode, after the network receives the information changed from the application mode of the user end, the network side reduces the discontinuous reception function. The time during which the receiving function is performed (ie, during sleep or during waking hours). For the description of the application mode of the user terminal, reference may be made to the above, and details are not described herein again.

Time (ie increase during sleep or reduce waking period). Conversely, if the network response time corresponding to the second application mode is less than the network response time of the first application mode, after receiving the information on the network, the network will increase the discontinuous reception function to receive the function. Time (ie reduce sleep period or increase awake period). For the description of the application mode of the user terminal, reference may be made to the above, and details are not described herein again.

Please refer to FIG. 5, which is a flowchart of a process 50 in a wireless communication system for managing a discontinuous reception function to reduce power consumption of a user end. The process 50 can be compiled into the code 214 and includes the following steps: Step 500: Start.

Step 502: When a setting of the user terminal is changed, the discontinuous receiving function of the user end is set according to the setting.

Step 504: End.

According to the process 50, when the setting of the client is changed (if the power setting/application mode setting/required network response time is changed by the user setting), the user terminal sets/applies according to the changed power setting/application mode. The network responds to the time to set the length of the awake period/sleep period in the discontinuous reception period of the UE.

For example, when the power setting of the UE is changed to a low power consumption state, the UE reduces the time for receiving the function in the discontinuous reception function, and when the power setting of the UE changes to a high power consumption state, the user The end will increase discontinuous connection The time at which the receiving function is performed in the receiving function.

The time during which the receiving function is performed in the discontinuous reception function. In another embodiment, when the application mode of the UE changes from a first application mode to a second application mode, and the power consumption represented by the second application mode is greater than the power consumption of the first application mode, the UE It will increase the time for receiving function in the discontinuous reception function. Conversely, when the power consumption represented by the second application mode is less than the power consumption of the first application mode, the UE reduces the time during which the receiving function is performed in the discontinuous reception function. In addition, the application mode can indicate the network response time required by the client, so when the network response time required by the client increases, the client reduces the time for receiving the discontinuous reception function, and when When the network response time required by the client is reduced, the UE increases the time for receiving function in the discontinuous reception function. It is worth noting that the detailed application modes (such as the switching state of the screen, sound and vibration) can be referred to the above, and will not be described here.
