The large-scale growth of smart phones has brought more challenges to operators, and the continuous growth of application services has led to an increasing demand for network capacity. To further enhance the capacity of the network, the network architecture evolves from a homogeneous network to a heterogeneous network. For example, as shown in Figure 1, a macro base station 1 is often covered with multiple access nodes 2. The access nodes 2 may be a small base station Pico, an indoor base station Femto, a low mobility base station LoMo, a local wireless access point AP, a low power transmitting node (LPN), etc., which do not have a paging message.

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

FIG. 3 is a schematic flowchart diagram of a paging method according to Embodiment 1 of the present invention. As shown in FIG. 3, the paging method according to the first embodiment of the present invention includes:

Step 101: Send a paging message to the user equipment during the activation period of the discontinuous transmission period or during the transmission period indicated by the transmission indication information of the preset pattern.

The base station works in the discontinuous transmission mode, that is, according to the discontinuous transmission period, the paging message is sent to the user equipment in a part of the period, and is in a dormant state in the remaining part of the period, that is, the paging is not sent to the user equipment. Message. The part of the time period in which the base station sends the paging message may be referred to as an activation period, and the period in which the base station is in the dormant state may be referred to as a sleep period. For example, the base station turns on a downlink transceiver for sending a paging message to the user equipment during the activation period according to the discontinuous transmission period, to send a paging message to the user equipment during the activation period. The downlink transceiver for transmitting the paging message to the user equipment is turned off during the period, so that the base station stops sending the paging message to the user equipment during the sleep period. Specifically, the discontinuous transmission (DXT) period is generally defined in the prior art to include a two-part time period, and the previous continuous time period constitutes a fixed activation period 4 (also referred to as Active Mode), and the continuous continuous period Form a fixed dormancy period 5 (also known as Opportunity DXT), as shown in Figure 4a. However, in practical applications, for a special need, the forced continuous activation period 6 may be forcibly set for a period of time after the continuous continuous period defined in the prior art, as shown in FIG. 4b, so that the base station is in a period of being in a sleep period. The downlink transceiver is turned on to send a paging message to the user equipment. Thus, as shown in FIG. 4a, the activation period of the discontinuous transmission period may be a fixed activation period 4 of the discontinuous transmission period. Or, as shown in FIG. 4b, the activation period of the discontinuous transmission period includes: a fixed activation period 4 of the discontinuous transmission period and the discontinuity The forced activation period of 6 is set within the fixed sleep period of the transmission cycle. The forced activation period 6 is less than or equal to the fixed sleep period 5. It should be noted that the setting of the forced activation period is not fixed. In the current period, it is possible that the forced activation period is equal to the fixed sleep period, but in the next period, the forced activation period may be Less than the fixed sleep period. The activation period of the discontinuous transmission period may be smaller than the paging period described in the prior art, that is, the time when the base station sends a paging message to all user equipments in its tracking area.

The sending indication information of the preset pattern is at least one, and each sending indication information corresponds to a preset sending period of a preset period. Specifically, the preset pattern may be characterized as a string of strings or other symbol strings. For example, character 1 is used to characterize the transmission indication information, and character 0 is the sleep indication information. The preset pattern can be characterized as: 0100001000 string. Assuming that the preset period is 10 ms, the period indicated by each character in the preset pattern is lms. The location marked with 1 is the transmission indication information, indicating that the base station can send a paging message within the transmission period indicated by the transmission indication information, that is, within 1 ms. The location marked as 0, that is, the sleep indication information, indicates that the base station is in a sleep state during the sleep period indicated by the sleep indication information. In fact, the sending indication information of the preset pattern may be the radio frame level indication information. For example, the character 1 in the character string represented by the preset pattern as described above corresponds to the radio frame level indication information, and the radio frame level indication The information corresponds to a radio frame in a preset period, and the base station can send a paging message to the user equipment in the radio frame. Or the sending indication information of the preset pattern may be the subframe level indication information, for example, the character 1 in the character string represented by the preset pattern, which is exemplified in the foregoing, is the subframe level indication information, and the subframe level indication information is Corresponding to one subframe in the preset period, the base station may send a paging message to the user equipment on the subframe.

Step 102: Send monitoring indication information to the user equipment, so that the user equipment determines the listening position according to the monitoring indication information, and monitors the paging message at the listening position.

Specifically, if the paging message is sent to the user equipment during the activation period of the discontinuous transmission period, the monitoring indication information that carries the discontinuous transmission period parameter and the pre-configured paging parameter is sent to the user equipment; or, The user equipment sends a interception carrying a sending location that sends the paging message And indicating, to the user equipment, the activation period information that carries the non-continuous transmission period, and is used to instruct the user equipment to use the specified subframe as the listening position, where the designated subframe is a distance The subframe in the activation period of the previous or next discontinuous transmission period of the latest listening position determined by the user equipment itself.

Further, the designated subframe may also be the same subframe as the listening position determined by the user equipment itself during the activation period of the previous or next discontinuous transmission period that is closest to the listening position determined by the user equipment itself. The sub-frame of the number. Or the specified subframe may further be separated from the monitoring location subframe number determined by the user equipment itself during an activation period of the previous or next discontinuous transmission period that is closest to the listening position determined by the user equipment itself. The subframe of the number of subframes. The listening position determined by the user equipment itself may be a listening position obtained by the base station that is used by the base station according to system message broadcast or dedicated signaling, and is in a paging position configuration information that is not a discontinuous transmission period state, or The user equipment is determined by using the PF and PO location determination rules in the prior art. For details, refer to the background art, and details are not described herein again.

If the paging message is sent to the user equipment during the transmission period indicated by the transmission indication information of the preset pattern, the monitoring indication information carrying the transmission location of the paging message is sent to the user equipment. The sending location of the paging message in the foregoing content includes: a frame number of a radio frame to which the subframe for transmitting the paging message belongs and/or a subframe number of the subframe.

In this embodiment, the base station sends a paging message only during the activation period of the discontinuous transmission period or during the transmission period indicated by the transmission indication information of the preset pattern, during the inactive period of the discontinuous transmission period or in the preset pattern. The base station is in a sleep state for a period of time other than the transmission period indicated by the transmission indication information in the preset period. Based on the paging method provided in this embodiment, on the one hand, the paging message to be sent by the base station is controlled to be sent during the activation period of the discontinuous transmission period or during the transmission period indicated by the transmission indication information of the preset pattern, and thus may be sufficiently Using the time resource in the transmission period, the prior art only avoids the sending finger in the inactive period of the discontinuous transmission period or in the preset period of the preset pattern. The sleep period is exceeded in the time other than the transmission period indicated by the indication information, which reduces the energy consumption of the base station. As shown in FIG. 5, a schematic flowchart of a paging method according to Embodiment 2 of the present invention is shown. As shown in FIG. 5, the second embodiment is a paging method for a base station to send a paging message to a user equipment during a fixed activation period of a discontinuous transmission period, including:

Further, the calculation starting point of the specific implementation formula of the multiple mapping rules enumerated in the foregoing embodiment starts at the position of SFN=0, and in the actual application, the starting point of the activation period of the discontinuous transmission period has It may not be at the position of SFN=0, and there is an offset value that is determined and stored when the base station is configured for the discontinuous transmission mode of operation. Therefore, when the base station determines that there is an offset value, the base station needs to modify the mapping rule formulas in the foregoing embodiment by using the following modification method. Specifically, the correction process is as follows:

Step S3: The base station acquires a start time offset value of an activation period of the discontinuous transmission period. Step S4: The base station corrects a frame number of the radio frame to which the subframe for transmitting the paging message belongs according to the start time offset value.

Specifically, the base station, according to the starting time offset value, corrects a frame number of the radio frame to which the subframe for transmitting the paging message belongs according to the following ninth formula:

The user equipment determines the listening position of the user equipment, and the user equipment is determined by using the PF and PO location determination rules in the prior art. For details, refer to the background art, and details are not described herein again. Of course, in practical applications, the paging message on the subframe during the activation period of the previous or next discontinuous transmission period that is closest to the listening position determined by itself may also be used as a protocol agreement of the user equipment. In this way, the base station may not send the indication information to the user equipment, and the user equipment directly listens to the homing in the subframe of the activation period of the previous or next discontinuous transmission period that is closest to the listening position determined by the user according to the protocol. Call the message.

For example, character 1 represents the transmission indication information and character 0 is the sleep indication information. The preset pattern can be characterized as: a string of 0100001000. 4 If the preset period is 10ms, the period of each character in the preset pattern is lms.

The user equipment needs to choose to camp on the macro base station (ie, the first base station in this embodiment) having the function of sending a paging message, and avoid staying at the access node that is under the macro base station. Thus, the present embodiment adds the above steps before step 501. Specifically, the macro base station sends information carrying all the access node identifiers under the macro base station to the user equipment by using broadcast or dedicated signaling. After receiving the information, the user equipment directly selects to camp under the macro base station, and avoids staying in the access section corresponding to the identifier. In the meantime, the macro base station sends a paging message to the user equipment, or the macro base station replaces the access node to send a paging message to the user equipment under the access node.

The location of the user equipment is determined by using the PF and PO location determination rules in the prior art. For details, refer to related content in the background art, and details are not described herein again.

Specifically, when the monitoring indication information is the monitoring indication information that carries the discontinuous transmission period parameter and the pre-configured paging parameter, the user equipment determines the listening position according to the discontinuous transmission period parameter and the pre-configured paging parameter. The following steps can be used to achieve:

First, the user equipment acquires its own device identification and actual paging cycle. Then, the user equipment determines, according to the discontinuous transmission period parameter, the pre-configured paging parameter, the device identifier, and the actual paging period, a frame of a radio frame to which a subframe of the paging message is monitored. number.

Specifically, if the discontinuous transmission period parameter includes: a non-continuous transmission period and a fixed activation period of the discontinuous transmission period, where the activation period is a fixed activation period of the discontinuous transmission period; And determining, by the sending period parameter, the pre-configured paging parameter, the device identifier, and the actual paging period, the frame number of the radio frame to which the subframe in which the paging message is monitored belongs, including:

Step sr, according to the device identifier, the actual paging cycle, and the pre-configured paging parameter, calculate the initial value of the frame number by using the following first formula:

SFN mod T=( ( T div N )x( UE — ID mod N )

Wherein, N=min (T, nB), SFN is the initial value of the frame number, T is the actual paging cycle, UE_ID is the device identifier, and nB is the pre-configured paging parameter, The value range of nB is {4T, 2T, Τ, T/2, T/4, T/8, T/16, T/32}, div represents the integer operation of the quotient, mod represents the modulo operation, min( *, *) means taking the minimum of the two numbers.

Step S2', according to the initial value of the frame number, the actual paging cycle, the discontinuous transmission period, and the fixed activation period of the discontinuous transmission period, the initial value of the frame number is determined by using a preset mapping rule. Mapping to a frame number corresponding to a fixed activation period of the discontinuous transmission period, where the frame number is a frame number of a radio frame to which the subframe in which the paging message is monitored belongs.

Or the preset mapping rule is specifically the following fifth formula:

SFN' mod T ₂ = floor( ( Ί _Χ Ι Ν' )x( UE ID mod Ν' ) )

Where N, =T or Τ ₂ .

Further, if the discontinuous transmission period parameter further includes: a start time offset value of the fixed activation period of the discontinuous transmission period, the method further includes:

Step S3, correcting the frame number of the radio frame to which the subframe of the monitoring paging message belongs according to the starting time offset value of the fixed activation period of the discontinuous transmission period. Specifically, according to the start time offset value of the fixed activation period of the discontinuous transmission period, the frame number of the radio frame to which the subframe for transmitting the paging message belongs is modified by using the following ninth formula:

SFN"=floor ( ( SFN ' x l0 + P0 + dtxStartOffset ) / 10 )

Finally, the user equipment determines, according to the discontinuous transmission period parameter, the pre-configured paging parameter, the device identifier, and the actual paging period, a frame of a radio frame to which a subframe of a paging message is to be located. number.

Specifically, if the discontinuous transmission period parameter includes: a non-continuous transmission period and a fixed activation period of the discontinuous transmission period, where the activation period is a fixed activation period of the discontinuous transmission period; The sending period parameter, the pre-configured paging parameter, the device identifier, and the actual paging period determine the subframe number of the subframe in which the paging message is monitored. The specific process is as follows:

Step S4, according to the actual paging period, the pre-configured paging parameter, the discontinuous transmission period, and the fixed activation period of the discontinuous transmission period, using the sixth formula to calculate the first cable Quoted value:

Ns=max( 1 , (nB / T)xF(T ₂ 1 Ύ _χ ) )

Alternatively, the first index value is calculated using the seventh formula:

Ns=max( 1 , (nB / T)x (Τ ₂ / T χ(Τ ₂ / Τ))

The Ns is a first index value, nB is the pre-configured paging parameter, and the value range of the nB is {4T, 2T, Τ, Τ/2, Τ/4, Τ/8, Τ/ 16 , Τ / 32} , for the discontinuous transmission period, Τ ₂ is a fixed activation period of the discontinuous transmission period, Τ is the actual paging period, and F(*) indicates that the ratio is greater than, less than, or closest to An integer specifying the expression *, max (* , *) means taking the larger of the two numbers.

Step S6': Obtain a subframe number corresponding to the first index value and the second index value according to a correspondence between the first index value, the second index value, and the subframe number.

Specifically, the base station pre-stores a correspondence between the first index value, the second index value, and the subframe number. It should be noted that, in the embodiment of the present invention, all paging messages sent by the base station in one paging cycle are controlled to be sent during the activation period of the discontinuous transmission period, so that the base station needs to be in a radio frame. The paging message is sent on the more subframes. Therefore, the correspondence between the index value and the subframe number in this embodiment is different from the corresponding relationship in the prior art, and more subframe numbers can be established according to actual requirements. In the correspondence list.

If the discontinuous transmission period parameters include: a non-continuous transmission period, a non-continuous transmission period The active activation period of the activation period and the discontinuous transmission period. The user equipment may determine a listening position of the listening paging message according to a rule. The rule is the same as the rule that the base station determines the sending location of the sending paging message during the fixed activation period and the mandatory activation period of the discontinuous transmission period, that is, according to the fixed activation period and the mandatory activation period of the base station, the mapping rule is adopted. The sending location determined by the user equipment by using the prior art is mapped to the corresponding location in the fixed activation period and the mandatory activation period. The mapping rule is artificially set.

Step 603: The user equipment, at the listening position, listens to a paging message sent by the base station during an activation period of the discontinuous transmission period or within a transmission period indicated by a sending indication information of the preset pattern. .

It may be added here that: in an actual application, the paging message on the subframe in the activation period of the previous or next non-continuous transmission period closest to the listening position determined by itself is monitored, or the user equipment itself is monitored from the user equipment. Determining a paging message on a subframe of the same subframe number as the listening position determined by the user equipment itself during the activation period of the previous or the last discontinuous transmission period of the latest listening position; or listening to the user equipment The paging message on the subframe of the predetermined number of subframes separated from the monitoring location subframe number determined by the user equipment itself during the activation period of the previous or subsequent non-continuous transmission period of the nearest determined listening position, Can be used as a protocol agreement for user equipment. In this way, the base station may not send the activation period carrying the non-continuous transmission period to the user equipment and is used to indicate the fixed activation of the previous or subsequent discontinuous transmission period of the user equipment that is closest to the listening position determined by the user equipment itself. The subframe in the period is used as the indication information of the listening position, and the user equipment directly listens to the paging message on the subframe in the activation period of the previous or next discontinuous transmission period that is closest to the listening position determined by the user according to the protocol.

Further, the paging method according to the foregoing sixth embodiment, before the step 603, the method further includes: the user equipment receiving, by the base station, a base station identifier that is sent by another base station that carries at least one working in a discontinuous transmission working mode. The message is to listen to the paging message under the base station corresponding to the base station identifier carried in the message according to the message selection. It should be noted that: In a heterogeneous network, a macro base station is covered by multiple access nodes, which may be a small base station Pico, an indoor base station Femto, a low mobility base station LoMo, a local wireless access point AP, Low Power Node (LPN), etc. None of these access nodes have the function of sending paging messages. Only the macro base station has the function of sending a paging message. The user equipment needs to choose to camp on the macro base station (ie, the first base station in this embodiment) having the function of sending a paging message, and avoid staying at the access node that is under the macro base station. Thus, the present embodiment adds the above steps before step 603.
