Background technique

The energy consumption of the terminal device is very important for the terminal device that uses the battery. For example, in some scenarios, a large number of Machine Type Communication (MTC) devices (such as sensors) use battery operation, and field battery replacement (or charging). It is a very large overhead. If these MTC devices are not predictive of charging or replacing the battery, the service life of the battery will even determine the service life of the MTC device.

Based on this, the Third Generation Partnership Project (3GPP) proposes a Power Saving Mode (PSM) for the terminal device. When the terminal device is in the idle state for a period of time, it will enter the PSM. Mode, in which the terminal device completely shuts down the RF module, thereby saving battery consumption and increasing the service life of the terminal device.

Specifically, the terminal device first enters the idle state from the PSM mode, and then the terminal device needs to pass the radio resource control when initiating the service in the idle state. (Radio Resource Control, RRC) connection establishment, non-access stratum (NAS) signaling connection establishment, authentication, security authentication, Packet Data Protocol (PDP) activation, radio access bearer ( Radio Access Bearer (RAB) has many processes such as connection establishment and channel reconfiguration, so that the terminal equipment consumes more energy.

Or, in another specific embodiment, the parameter negotiation unit 20 needs to receive a first request message sent by the terminal device, where the first request message is used to request the access network device to configure the first time information and/or the second The time information; finally determining the first time information and the second time information according to the first request message, and transmitting the finally determined first time information and/or the second time information to the terminal device.

The state synchronization unit 21 is configured to determine the state of the terminal device according to the first time information and the second time information determined by the parameter negotiation unit 20, and is mainly a state in which the terminal device switches between the connected state and the power saving mode.

In a specific embodiment, the first time information and the second time information that are specifically determined by the parameter negotiation unit 20 are respectively a first preset time and a second preset time; and the state synchronization unit 21 is specifically configured to be used when When the terminal device enters the connected state for more than the first preset time and does not have uplink and downlink data, determining that the terminal device enters a power saving mode; when the terminal device enters the power saving mode or the terminal When the time when the device enters the connected state reaches the current time exceeds the second preset time, it is determined that the terminal device returns the connected state from the power saving mode.

Further, if the terminal device enters the power saving mode or the time when the terminal device enters the connection state to the current time does not exceed the second preset time, temporarily decide to enter the connection from the power saving mode.

(2) In the CELL_FACH state, the terminal device is not assigned a dedicated transport channel and needs to listen to a downlink FACH channel; the terminal device is assigned a default uplink common channel or an uplink shared transport channel such as RACH; the location of the terminal device is at the cell level. Known by the UTRAN, specifically, the cell reported by the terminal device when the cell update was last initiated.

The terminal device performs the following tasks: listening to a FACH; listening to the broadcast channel (BCH) of the current serving cell to decode system information; initiating a cell update procedure when the cell changes; in the random access channel (Random Access Channel) , RACH) transmits uplink control signaling and small data packets.

In the CELL_FACH state, if the data service is not activated for a period of time, the terminal device will enter the CELL_PCH state to reduce power loss, and perform cell update when the terminal device temporarily leaves the CELL_PCH state.

(3) In the CELL_PCH state, the terminal device is not assigned a dedicated channel; the terminal device cannot have any uplink activity; the logical channel of the Dedicated Control Channel (DCCH) cannot be used. If the network side attempts to initiate any activity, it needs A paging request is sent on the PCCH logical channel of the cell where the terminal device is located; the location of the terminal device is known by the UTRAN at the cell level, specifically, the cell reported when the terminal device initiates the cell update when the terminal device is in the CELL_FACH state.

The terminal device performs the following tasks: using Discontinuous Reception (DRX) technology to monitor information on the PCH transmission channel at a specific paging moment, specifically, listening to the paging moment according to the DRX cycle and receiving the homing on the PCH. Calling the message; listening to the BCH of the serving cell where the terminal device is currently located to decode the system information; and initiating the cell update process when the cell where the terminal device is located changes.

The terminal device can switch from the CELL_PCH state to the CELL_FACH state or the CELL_DCH state through UTRAN paging or through any uplink access.

(4) In the URA_PCH state, it is similar to the terminal device in the CELL_PCH state, except that the terminal device initiates the location update process only when the routing area changes (rather than the cell change). The network side only has the information of the routing area of the terminal device, and needs to be paged in the entire routing area to find Terminal Equipment.

(5) The power saving mode in this embodiment may include a first power saving mode or a second power saving mode. In the second power saving mode, the radio frequency module of the terminal device is turned off, that is, uplink and downlink transmission cannot be performed. The terminal device does not listen to the paging information, and the core network device cannot directly connect or page to the terminal device, but still maintains the RRC connection and the PDP attachment. In the first power saving mode, the terminal device not only needs to reserve the configuration of the access layer, but also needs to periodically monitor the paging information. When the monitored paging information indicates that there is data transmission, the terminal device may have the first power saving mode. Switch to connected state.

In this embodiment, when the terminal device enters the connected state for more than the first preset time and does not have uplink and downlink data, it may directly enter a power saving mode, such as a first power saving mode or a second power saving mode, where the first pre- The set time can be obtained by the terminal device and the access network device or negotiated with the core network.

If the terminal device enters the power saving mode in this case, the configuration of the access layer when the terminal device is in the connected state is retained, including the information of maintaining the connection such as the RRC connection, and may also include the Iu interface (the access network and the core network) The information of the connection interface, the authentication information, the security authentication information, and the PDP activation information may also maintain any timer that is started when the terminal device is in the connected state, such as the timer T305. The timer T305 is a timer that is started when the terminal device enters the connected state. When the T305 times out, the terminal device performs a cell update operation.

Step 103: According to the second time information acquired in the above step 101, the power saving mode is switched to the connected state, and when the terminal device returns from the power saving mode to the connected state, the transmission is initiated according to the configuration of the reserved access layer. The terminal device returns from the power saving mode to the connected state, and then the terminal device can directly use the RRC connection maintained in the power saving mode, and performs tasks in the connected state, such as cell update (Cell Update, CU), and tracking area update (Tracking). Area Update, TAU) or Routing Area Update (RAU).

Specifically, the second time information may be a second preset time, when the time when the terminal device enters the power saving mode or the time when the terminal device enters the connected state reaches the current time exceeds the second preset time, The terminal device can return from the power saving mode to the connected state.

In a specific embodiment, the terminal device sets two timers, namely timers T1 and T2. In one case, when the terminal device enters the connected state, the timers T1 and T2 can be started simultaneously; in another case, When the terminal device enters the connected state, the timer T1 is started, and when the terminal device enters the power saving mode, the timer T2 is started. Then in the method of this embodiment, if the timer T1 times out and there is no When the data is uplink and downlink, the terminal device enters the power saving mode from the connected state. When the timer T2 times out, the terminal device returns from the power saving mode to the connected state.

In another specific embodiment, in one case, when the terminal device has data transmission or signaling transmission in the power saving mode, the terminal device may not need to wait for the time when the terminal device enters the power saving mode or the terminal device enters the connected state. The time point to the current time exceeds the second preset time, and the channel paging state is returned from the power saving mode. In another case, when the terminal device has signaling transmission in the power saving mode, it is required to wait for the terminal device to enter the power saving mode or the time when the terminal device enters the connected state to the current time exceeds the second preset. At the time, the channel paging state is returned from the power saving mode.

The signaling transmission may include: the transmission of the cell update signaling after the terminal device enters the connected state, specifically, when the terminal device enters the connected state, the foregoing timer T305 is started, if the terminal device is in the power saving mode The timer T305 expires, and the terminal device needs to perform cell update signaling transmission;

The foregoing signaling transmission may further include: retransmission signaling after the terminal device is not in the service state, where the terminal device is not in the service state when the terminal device is in the power saving mode, that is, the terminal device may A timer T316 is started, and if the timer T316 times out, the terminal device needs to transmit signaling for reconnecting the network.

It can be seen that, in this embodiment, the terminal device directly converts the terminal device from the power saving mode to the connected state by using the foregoing steps 102 and 103, and in the power saving mode, the terminal device retains the configuration of the access layer when in the connected state. Therefore, the terminal device can directly initiate transmission in the connected state, and in the prior art, the terminal device needs to enter the idle state from the PSM mode first, and then initiate the transmission in the idle state. In comparison, in the embodiment of the present invention, the slave connection The process of initiating transmission will be less, and the transmission may be directly transmitted through the reserved RRC connection and the connection of the Iu interface, thereby saving RRC connection establishment, NAS signaling connection, authentication, and security authentication when the transmission is initiated from the idle state. And the process of activation of the PDP, the power consumption of the terminal device is reduced, and the purpose of the terminal device node is achieved.

When the data is used, the core network device determines that the terminal device enters the power saving mode; when the terminal device enters the power saving mode or the time when the terminal device enters the connected state to the current time exceeds the second preset time, the core network device It is determined that the terminal device returns from the power saving mode to the connected state.

It can be seen that, in this embodiment, the terminal device can directly switch between the power saving mode and the connected state, and when entering the power saving mode from the connected state, the terminal device retains the configuration of the access layer in the connected state, and In this process, the access network device needs to send the third state information to the core network device, so that the core network device counts the time when the terminal device enters the connected state, and determines that the terminal device enters the power saving mode according to the timed time. When not paging or not transmitting data to the terminal device, or simply paging the terminal device periodically, this can save the signaling process of the core network device.

(1) The core network device receives the second state information sent by the access network device, where the second state information includes: information that the terminal device leaves the power saving mode, where the second state information is the terminal device After the connection state enters the power saving mode, the access network device sends; if the core network device determines, according to the second state information, that the terminal device returns to the paging entry state, starts paging or starts sending data to the terminal device, Determine when to leave the power save mode.

In one case, if the terminal device sends information to the terminal device through the access network device after the terminal device enters the power-saving mode, the network device receives the information sent by the access network device. The second state information, where the information included in the second state information indicates the time information of the terminal device leaving the power saving mode, the core network device may determine, according to the second state information, that the terminal device leaves the In the power saving mode, normal paging starts or data transmission starts to the terminal device. In another case, if the terminal device enters the power saving mode from the connected state, it also goes from the power saving mode. When the connection state is returned, the core network device receives the second state information sent by the access network device, and the information included in the second state information indicates that the terminal device has left the power saving mode.

The method provided in the embodiment of the present invention is described in the following specific application embodiments. In these embodiments, the access network device is an RNC, and the core network device is an SGSN, where the power saving mode of the terminal device is the foregoing. Two power saving modes.

Embodiment 7 of the method of the present invention, the method flow chart shown in FIG. 13 includes:

Step 701: When the terminal device sends a NAS message, such as an attach request message, to the SGSN, or sends a TAU/RAU request message (Request Message), the first preset time and the second preset time recommended by the terminal device are carried in the message. Used to request the SGSN to configure these two times.

In step 702, the SGSN carries the first preset time and/or the second preset time finally determined by the SGSN in the attach accept message or the TAU/RAU accept message.

It can be understood that, after the terminal equipment and the SGSN negotiate the first preset time and the second preset time, the terminal device can use Cell Update or Radio Channel Reconfiguration. The message sends the negotiated first preset time and the second preset time to the RNC; at the same time, the RNC also responds to the terminal device, and the RNC is Whether the function of direct connection between the connection state and the power saving mode is supported, only the terminal device and the RNC support the subsequent steps.

Alternatively, the SGSN notifies the RNC of the negotiated first preset time and the second preset time.

Or, in other cases, the RNC carries information about whether the RNC supports the function of directly connecting the connection state and the power saving mode in the system information block (SIB), and sends the information to the terminal device, which is executed only when supported. The steps of 701 and 702 above.

Step 703: When the terminal device enters the connected state, the timers T1 and T2 are started at the same time, and the timeout time is the first preset time and the second preset time respectively. If the timer T1 times out and there is no uplink and downlink data, the terminal The device enters the power-saving mode from the connected state. At this time, the terminal device is unreachable to the core network, that is, the core network device cannot page or cannot send data to the terminal device, and the configuration of the AS remains unchanged. The running timer continues to run, but the terminal device does not need to perform any connected tasks. If the timer T2 exceeds the time when the terminal device enters the connection state to the current time exceeds the second preset time, the terminal device returns from the power saving mode to the connected state.

It should be noted that, in one case, when the terminal device is in the power saving mode, if there is data transmission or signaling transmission, the terminal device may end the power saving mode and enter the connected state, and initiate the transmission service from the connected state. In another case, when the terminal device is in the power saving mode, if there is signaling transmission, the terminal device waits for the timer T2 to time out before performing signaling transmission. The following describes the cell update operation when the terminal device enters the connected state by using the connection operation as an example.

When the terminal device enters the connected state, a timer T305 is started for periodic cell update in this state. specifically:

A. If the time of the timer T305 is less than the time of the timer T1, when the terminal device does not enter the power saving mode, the terminal device performs a cell update operation, so that the terminal device leaves the connected state and enters another state, so that the timer is caused. T1 terminates and the terminal device never enters power save mode.

B. If the time of timer T305 is equal to the time of timer T1, T305 and T1 will time out at the same time, and the terminal device can only meet the action requirement of one timer. To ensure that the terminal device can enter the power-saving mode, the timer T305 is not timed out. Corresponding cell update behavior.

C. If the time of the timer T305 is greater than the time of the timer T1 and less than the time of the timer T2, it indicates that the timer T305 times out after the terminal device enters the power saving mode, and the cell update operation needs to be performed. The device can immediately end the power saving mode to perform the cell update operation. Or the cell update operation is performed only when the timer T2 times out.

D. If the time of the timer T2 is the time of the timer T305, the terminal device needs to perform a cell update operation each time it returns from the power saving mode to the connected state.

In step 704, the RNC notifies the SGSN of the information about the terminal device entering the connection state, and the SGSN starts the timing according to the first preset time and the second preset time negotiated in the foregoing steps 701 and 702. T1 and T2, if the terminal device does not have uplink and downlink data after the timer T1 expires, the SGSN stops paging or stops sending data to the terminal device, and starts to page or start transmitting data to the terminal when the timer T2 times out. device. Specifically, the RNC may notify the SGSN by using a DIRECT INFORMATION TRANSFER message, or may notify the SGSN by other messages such as a Location Report.

If the terminal device leaves the connected state before the timer T1 times out, the RNC sends the information that the terminal device leaves the connected state to the SGSN, so that the SGSN stops the operations of the timings T1 and T2. If the terminal device decides to end the power saving mode after the timer T1 expires and the timer T2 does not time out, the RNC sends the information about the terminal device leaving the power saving mode to the SGSN, so that the SGSN starts paging or starts sending data. To the terminal device.

Take the "direct information transmission" message as an example to illustrate how the RNC carries these status information, as shown in Table 1:

Table 1

It can be seen that the direct information transmission message may include an information element (IE)/group name (Group Name), presence (Presence), cell type and reference (IE type and reference), and semantic description (Semantics description). , whether it is a criticality (Criticality) and a specified critical (Assigned Criticality) and other fields. The direct information transmission message may include the following message: Message Type, Inter-system Information Transfer Type, CN Domain Indicator, Global RNC Flag (Global) RNC-ID), the global core network identifier (Global CN-ID), the extended RNC identifier (Extended RNC-ID), and the terminal device enters or leaves the PCH state (Enter/Leave PCH state) and other cells.

The “O” value of the “Entering or Leaving State” cell indicates that the terminal device enters the PCH state. In other cases, the value “1” may indicate that the terminal device enters the PCH state, and the value “0” indicates that the terminal device leaves the PCH. status.

Embodiment 8 of the method of the present invention, the method flow chart shown in Figure 14, comprising:

Step 801: The terminal device sends an attach request or a TAU/RAU request message to the SGSN, where the second preset time is carried.

Step 802, the SGSN returns an attach accept, or a TAU/RAU accept message to the terminal device, where The second preset time is finally determined. Similar to the seventh embodiment, the terminal device may also send the second preset time to the RNC to determine that the RNC also supports the function of switching between the connected state and the power saving mode, and then performs the subsequent steps. Alternatively, the SGSN notifies the RNC of the negotiated second preset time.

Step 803: When the terminal device enters the connected state, the timer T1 is started. When the timer T1 times out and there is no uplink and downlink data, the terminal device enters the power saving mode and starts the timer T2. If the timer T2 is exceeded (that is, the terminal device) When the time to enter the power saving mode exceeds the second preset time), the terminal device returns from the power saving mode to the connected state. The timeout period of the timer T2 is the second preset time negotiated in the foregoing steps 801 and 802. The timer T1 can be replaced by the timer T305, that is, when the terminal device enters the connected state, a timer T305 is started. The time of the timer T1 can also be negotiated according to the methods of steps 801 and 802 above to obtain the first preset time.

In this embodiment, the operation performed by the terminal device according to the relationship between the times of the timers T1, T2, and T305 is similar to that of the above-mentioned Embodiment 7, except that in the case of the above C, when the timer T305 is longer than the timing The corresponding operation is performed when the time of the timer T1 is less than the sum of the times of the timers T1 and T2; and in the case of the above D, when the time of the timer T305 is equal to the sum of the times of the timers T1 and T2 , perform the above corresponding operations.

Step 804, while performing the above step 803, if the terminal device enters the power saving mode from the connected state, the RNC notifies the SGSN of the information that the terminal device enters the power saving mode, so that the SGSN stops paging or stops sending data to the terminal. The device, and the SGSN may start the timer T2 according to the negotiated second preset time. If the timer T2 times out, the SGSN starts paging or starts sending data to the terminal device.

If the terminal device temporarily decides to return to the connected state from the power saving mode when the timer T2 has not timed out, the RNC notifies the SGSN of the information that the terminal device leaves the power saving mode, so that the SGSN starts paging or starts sending data to the terminal device. .

Specifically, the RNC may send the status information to the SGSN by using a direct information transmission message or other message, where the structure of the direct information transmission message is similar to that in the foregoing Table 1, except that, in this embodiment, in the direct information transmission message. There is no "entry or leave state" cell, but a "into the power save mode identification" cell, which is used to indicate whether the terminal device enters the power save mode.

Embodiment 9 of the method of the present invention, the method flow chart shown in Figure 15, comprising:

Step 901: The terminal device sends an RRC message to the RNC, where the first preset time and the second preset time are carried, and the RRC message may be a Service Request or a Cell Update message.

Step 902: The RNC returns the first determined preset time and the second preset time to the terminal device, where the RNC may be sent to the terminal device in a Cell Update Confirm message. The terminal device or the RNC sends the finally determined first preset time and the second preset time to the SGSN to complete the three-party negotiation.

Step 903: When the terminal device enters the connected state, the timer T1 is started. When the timer T1 times out and there is no uplink and downlink data, the terminal device enters the power saving mode and starts the timer T2. If the timer T2 times out, the terminal device Return to the connected state from the power saving mode. The timeouts of the timers T1 and T2 are the first preset time and the second preset time, respectively.

In step 904, when the state of the terminal device is changed, the information notified by the RNC to the SGSN is similar to the foregoing step 604, and is not described herein.

In another case, when the SGSN receives the information that the terminal device sent by the RNC enters the power saving mode, the RNSN may not notify the SGSN that the terminal device leaves the power saving mode without starting the timer T2. In this way, the SGSN can know when to start paging or start sending data to the terminal device.

Embodiment 10 of the method of the present invention, the method flow chart shown in Figure 16, comprising:

Step 1001: The terminal device sends an RRC message to the RNC, where the first preset time and the second preset time are carried, and the RRC message may be a service request or a cell update message.

Step 1002: The RNC returns the first determined preset time and the second preset time to the terminal device, where the RNC may be carried in the cell update confirmation message and sent to the terminal device. The terminal device sends the finally determined first preset time and the second preset time to the SGSN by the RNC to complete the three-party negotiation.

Step 1003: When the terminal device enters the connected state, the timer T1 is started. When the timer T1 times out and there is no uplink and downlink data, the terminal device enters the power saving mode and starts the timer T2. If the timer T2 times out, the terminal device Return to the connected state from the power saving mode. The timeouts of the timers T1 and T2 are the first preset time and the second preset time, respectively.

Step 1004, while performing the above step 1003, when the terminal device enters the power saving mode, the RNC does not send the information that the terminal device enters the power saving mode to the SGSN, so the SGSN still Paging or sending data to the terminal device; when the information sent by the SGSN to the terminal device reaches the RNC, the RNC notifies the SGSN of the time information that the terminal device leaves the power saving mode, so that the SGSN knows when to start paging or The data is sent to the terminal device, or the RNC does not notify the SGSN of the time information that the terminal device leaves the power saving mode, but sends a failure message to the SGSN or does not send any reply to the SGSN.

The paging method in the embodiment of the present invention is described below:

It should be noted that, in the embodiment of the present invention, the length of the discontinuous reception period in the first discontinuous reception technology is greater than the length of the discontinuous reception period in the second discontinuous reception technique, and the discontinuous reception in the second discontinuous reception technique The maximum length of the period is 5.12 seconds. The second discontinuous reception technology may be a normal discontinuous reception technology DRX. The maximum length of the discontinuous reception period may be 5.12 seconds. The first discontinuous reception may be performed. The technique may be an enhanced discontinuous technology eDRX, the length of the discontinuous reception period in the first discontinuous reception technique being greater than the length of the discontinuous reception period in the second discontinuous reception technique, for example, 40.96 seconds. The first discontinuous reception technology is different from the second discontinuous reception technology in that the UE calculates the paging occasion mechanism, and only the period of the discontinuous reception is lengthened.

It should be noted that, after determining the length of the discontinuous reception period, the paging occasion of the paged user equipment (assumed to be the UE) may be calculated:

Specifically, according to the International Mobile Subscriber Identification Number (IMSI) of the paged user equipment and the discontinuous reception period length of the paged user equipment, the paged can be calculated according to the following formula (1). Paging opportunity of the user equipment;

PO={(IMSI/K)%(DRXcycle/PBP)}*PBP+n*DRXcycle+FO;n=0,1,2...m, when n≦m, PO≦4095; Formula (1)

Where m is the maximum value of n, and when n>m, PO>4095.

In the above formula (1), PO is the paging occasion of the paged user equipment, DRXcycle is the discontinuous reception period length of the paged user equipment, and K is the channel carrying the paging message in the cell. The number is % modulo operation. For the frequency division multiplexing system, PBP is 1 and FO is 0.

The following describes the paging method in the embodiment of the present invention in combination with the signaling interaction between the UE, the RAN, and the core network device in the network system. In the following embodiment, the core network device is used as the SGSN as an example, in practical applications. It can also be other core network elements, which are not limited here:

Referring to FIG. 17, which is a signaling flowchart of a paging method according to an embodiment of the present invention, an embodiment of a paging method in an embodiment of the present invention includes:

1701: The UE negotiates a first parameter with the SGSN, where the first parameter is used to determine a length of the discontinuous reception period in the first discontinuous reception technology;

The length of the discontinuous reception period in the first discontinuous reception technique is greater than the length of the discontinuous reception period in the second discontinuous reception technique, and the maximum length of the discontinuous reception period in the second discontinuous reception technique The value is 5.12 seconds;

In an actual application, the negotiation process may be completed by using a NAS message between the UE and the SGSN, specifically:

The UE may send an attach request or a Route Area Update (RAU) request to the SGSN, where the request carries the suggested first parameter; after receiving the attach request or the routing area update request that carries the suggested first parameter, the SGSN The attach request or routing area update request carrying the configured first parameter may be returned to the UE to determine the first parameter.

It can be understood that the first parameter is a first discontinuous reception technology eDRX parameter for determining the length of the discontinuous reception period in the first discontinuous reception technique.

1702, when the SGSN determines that the RAN supports the first discontinuous receiving technology, the SGSN sends the first parameter to the RAN through the Iub interface;

It should be noted that the SGSN determines that the RAN supports the first discontinuous reception technology. The SGSN may determine that the RAN supports the first discontinuity by means of Iu interface signaling or manual configuration. There are many other ways to receive the technology, which is not limited here.

It can be understood that, in this step, the SGSN sends the first parameter to the RAN through the Iub interface. In an actual application, optionally, if the SGSN determines that the RAN does not support the first discontinuous receiving technology, the SGSN may also pass the SGSN. The Iub interface sends a second parameter for determining the length of the discontinuous reception period in the second discontinuous reception technique to the RAN.

1703. The RAN calculates the third paging occasion by using the first discontinuous receiving technology according to the received first parameter.

In this step, the RAN supports the first discontinuous receiving technology. After receiving the first parameter sent by the SGSN, the RAN calculates the third paging occasion by using the first discontinuous receiving technology according to the received first parameter.

Optionally, in a practical application, if the RAN does not support the first discontinuous receiving technology, the RAN calculates the second non-continuous receiving technology based on the second parameter of the second discontinuous receiving technology that is sent by the SGSN. Four paging opportunities.

1704. The RAN indicates, by using a broadcast message, whether the RAN supports the first discontinuous receiving technology.

Specifically, when the RAN supports the first discontinuous receiving technology, the RAN may carry the first discontinuous receiving technology flag in the sent broadcast message;

Optionally, the first discontinuous reception technology indicator may be a first discontinuous reception technology indication, or may be a preset length discontinuous reception period, and the preset length is greater than the second discontinuous reception technology DRX The maximum value of the length of the continuous receiving period is 5.12 seconds. Other first non-continuous receiving technology flags may also be used, which are not limited herein.

It can be understood that step 1704 can be performed after step 1701 and any time before step 1705, which is not limited herein.

1705. When the UE determines, according to the broadcast message, that the RAN supports the first discontinuous receiving technology, the UE calculates the first paging by using the first discontinuous receiving technology according to the first parameter. opportunity;

The UE may determine, according to the broadcast message, that the RAN supports the first discontinuous reception technology. Specifically, the UE may determine whether the first discontinuous reception technology identifier is carried in the broadcast message.

When it is determined that the first discontinuous reception technology flag is carried, the UE determines that the RAN supports the first discontinuous reception technology;

In this step, when the UE determines, according to the broadcast message, that the RAN supports the first discontinuous reception technology, the UE calculates the first paging occasion by using the first discontinuous reception technology according to the first parameter.

In an actual application, when the UE determines, according to the broadcast message, that the RAN does not support the first discontinuous connection When receiving the technology, the UE may calculate the second paging occasion by using the second discontinuous reception technology.

1706. The UE and the RAN complete the paging according to the calculated paging occasion.

In this step, the RAN may send a paging indication to the UE according to the calculated paging occasion, and the UE may listen to the paging indication sent by the RAN according to the calculated paging occasion, and complete the paging according to the calculated paging occasion.

Specifically, the network side calculates a paging occasion of the paged user equipment, and sends a paging indication to the paged user equipment at the paging occasion, where the paging indication carries the identifier of the paged user equipment and seeks Call data.

When the paging occasion of the user equipment arrives, the user equipment monitors a PICH (Page Indication Channel) and parses the paging indication value of the PICH channel, if the paging indication in the PICH channel is resolved If the value is 1, the user equipment receives the paging message, and determines whether the identifier of the user is the same as the identifier carried in the paging message. If the information is the same, the paging data is retained. If not, the paging data is discarded.

In the embodiment of the present invention, the UE can automatically select whether to use the first discontinuous reception technology to calculate the paging occasion or the second discontinuous reception technology to calculate the paging according to whether the broadcast message sent by the RAN carries the first discontinuous reception technology flag. Timing improves the adaptability of the UE in network systems using different discontinuous reception technologies.

The paging method in the embodiment of the present invention is described in the above, from the perspective of the signaling interaction of each device. The following describes the paging method in the embodiment of the present invention from the perspective of each device:

First, the paging method in the embodiment of the present invention is described from the perspective of the UE:

Referring to FIG. 18, another embodiment of the paging method in the embodiment of the present invention includes:

The UE may receive a broadcast message sent by the RAN, where the broadcast message is used to indicate whether the RAN supports the first discontinuous reception technology.

The UE may determine, according to the broadcast message, whether the RAN supports the first discontinuous reception technology;

If it is determined that the RAN supports the first discontinuous receiving technology, step 1803 is performed;

If it is determined that the RAN does not support the first discontinuous reception technology, step 1804 is performed.

Optionally, the UE may determine whether the first discontinuous reception technology flag is carried in the broadcast message.

When determining to carry the first discontinuous reception technology flag, the UE determines that the RAN supports the first discontinuous reception technology;

1803. When the UE determines, according to the broadcast message, that the RAN supports the first discontinuous receiving technology, the UE calculates the first paging by using the first discontinuous receiving technology according to the first parameter. opportunity;

It should be noted that the first parameter is used to determine the length of the discontinuous reception period of the first discontinuous reception technology. After the UE determines the length of the discontinuous reception period, the first search may be calculated according to the above formula (1). Calling time.

1804. When the UE determines, according to the broadcast message, that the RAN does not support the first discontinuous receiving technology, the UE uses the second discontinuous receiving technology to calculate a second paging occasion.

In a practical application, in a certain application scenario, since the RAN can only support the first discontinuous reception technology or does not support one of the first discontinuous reception technologies, steps 1803 and 1804 are performed according to actual conditions. Only one step will be executed.

1805. The UE listens to the paging indication sent by the RAN according to the calculated first paging occasion or the second paging occasion.

It should be noted that since the first discontinuous reception technology supports listening for paging indicators on multiple paging indicator channels, it is optional:

When the UE determines, according to the broadcast message, that the RAN does not support the first discontinuous reception technology, the UE listens to the RAN according to the calculated second paging occasion on the first paging indicator channel. Paging instructions issued;

When the UE determines, according to the broadcast message, that the RAN supports the first discontinuous reception technology, the UE performs the first calculation on the second paging indicator channel or the first paging indicator channel. Paging opportunity to listen to a paging indication sent by the RAN, the second paging indicator channel and the The first page indicates that the channel is different.

Of course, in a practical application, even if the RAN supports the first discontinuous reception technology, the UE may select to listen to the paging indicator sent by the RAN according to the calculated first paging occasion only on the first paging indicator channel. This is not a limitation.

The discontinuous reception technology logo is not limited herein.

Step 1901 can be performed at any timing before step 1904, which is not limited herein.

1902. The RAN receives a first parameter sent by a core network device, where the first parameter is used to determine a length of a discontinuous reception period in the first discontinuous reception technology.

Similar to step 1703, it will not be described here.

1904. The RAN sends a paging indication to the UE at the calculated paging occasion.

In this step, the RAN that supports the first discontinuous reception technology can inform the UE of its own capability by using the broadcast message, and the UE automatically selects to use the first discontinuous according to whether the broadcast message sent by the RAN carries the first discontinuous reception technology flag. Receive technology calculates paging occasions, or uses second non-connected Continued receiving technology to calculate the paging opportunity.
