Description

System message acquisition and indication method, device and equipment

Technical Field

The present invention relates to the field of communications, and in particular, to a method, an apparatus, and a device for acquiring and indicating a system message.

Background

A User Equipment (UE) of a Machine Type Communication (MTC) Type needs to acquire a system message broadcasted by a serving cell every time the UE accesses a base station or every time the UE wakes up from a sleep state, so as to determine whether the system message of the serving cell corresponding to the base station changes. Thus, a large amount of power of the ue needs to be consumed, and Long Term Evolution (LTE) MTC requires the ue to achieve low power consumption, so that an improvement on a system message acquisition manner is needed.

In the related art, when a System message of a serving cell changes, an evolved Node B (E-UTRAN Node B, eNB) sets indication Information in a Master Information Block (MIB) to 1, and a ue acquires the MIB broadcasted by the serving cell and reads the indication Information in the MIB each time the ue accesses the base station or wakes up from a sleep state each time, and if the indication Information is 1, the ue determines that it is impossible to skip a System Information Block 1(System Information Block Type1-Bandwidth Reduced, SIB1-BR) for MTC technology, and continues to acquire SIB 1-BR; if the indication information is 0, the user equipment determines that the SIB1-BR can be skipped. Here, skip is a meaning of not reading.

The user equipment wakes up frequently or moves frequently between cells, causing the user equipment to read system messages (such as SIB1-BR) frequently, resulting in large power consumption of the user equipment.

Disclosure of Invention

In order to solve the problem that power consumption of user equipment is high due to the fact that the user equipment needs to read system messages frequently when the user equipment wakes up frequently in a serving cell or moves frequently between cells, embodiments of the present invention provide a method, an apparatus and a device for acquiring and indicating system messages. The technical scheme is as follows:

in a first aspect, a method for acquiring a system message is provided, where the method includes: the method comprises the steps that user equipment receives first indication information sent by first network equipment corresponding to a first cell, wherein the first indication information corresponds to a first system message; and the user equipment skips the first system message according to the first indication information or reacquires the first system message according to the first indication information.

The user equipment determines whether to skip the first system message or to reacquire the first system message according to the first indication information sent by the first network equipment, and does not need to frequently acquire the first system message every time the base station is accessed or awaken from a sleep state, or does not need to frequently acquire the first system message every time the target cell is reselected, so that the power consumption and the access delay of the user equipment are reduced.

In a possible implementation scheme, the skipping, by the ue, the first system message according to the first indication information, or reacquiring the first system message according to the first indication information includes: when the first system message is a system message of a second cell adjacent to the first cell, the user equipment skips the first system message when reselecting the second cell according to the first indication information, or reacquires the first system message when reselecting the second cell according to the first indication information, wherein the first cell corresponds to the first network equipment.

In a possible implementation scheme, the skipping, by the ue, the first system message according to the first indication information, or reacquiring the first system message according to the first indication information includes: and when the first system message is the system message of the first cell, the user equipment skips the first system message according to the first indication information, or reacquires the first system message according to the first indication information, wherein the first cell corresponds to the first network equipment.

Herein, the first system message may be all system messages of the first cell or the second cell, including MIB, SIB1-BR (or SIB1), all other SIBs; or the first system message is a part of the system message of the first cell or the second cell, which is not limited herein. For example, the first system message is a MIB message, or the first system message is SIB1-BR (or SIB1), or the first system message is MIB and SIB1-BR, and so on.

In a possible implementation scheme, the skipping, by the user equipment, the first system message when reselecting the second cell according to the first indication information, or reacquiring the first system message when reselecting the second cell according to the first indication information, includes:

when the first indication information is used for indicating whether the first system message is changed or not, the user equipment reacquires the first system message when reselecting the second cell and the first indication information indicates that the first system message is changed, or the user equipment skips and acquires the first system message when reselecting the second cell and the first indication information indicates that the first system message is not changed;

alternatively, the first and second electrodes may be,

when the first indication information is used for indicating whether the user equipment skips the first system message, the user equipment skips the first system message when reselecting the second cell and the first indication information is used for indicating the user equipment to skip the first system message, or the user equipment reacquires the first system message when reselecting the second cell and the first indication information is used for indicating the user equipment to prohibit skipping the first system message.

When the first indication information indicates that the first system message changes or indicates the user equipment to reacquire the first system message, the user equipment reacquires the first system message, and the accuracy of the first system message stored in the user equipment is ensured; when the first indication information indicates that the first system message is not changed or indicates the user equipment to skip the first system message, the user equipment skips the first system message, and power consumption and access delay of the user equipment are reduced.

In a possible implementation scheme, the first indication information is carried in DCI of a paging message or the paging message, or MIB of the first cell or MIB of the second cell.

In a possible implementation scheme, when first indication information is carried in the MIB and the first indication information is used to indicate whether a first system message is changed or the first indication information is used to indicate whether the user equipment skips the first system message, a change in the MIB caused by the change in the first indication information triggers paging.

In a possible implementation scheme, the transmission duration of the first indication information is N cycles, and the cycle is a modification cycle MP or a DRX cycle or an eDRX cycle.

In another possible implementation, the first system message is unchanged for N periods.

In a possible implementation scheme, the result of the modulo operation of the sending start system frame number of the first indication information to N periods is 0.

Since the result of the modulo operation of the initial system frame number sent by the first indication information to N periods is 0, the user equipment can determine the initial time and the end time for sending the first indication information, and since the first system message is not changed in the N periods, the user equipment only needs to acquire the first system message once in the N periods, and does not need to acquire the first system message frequently when accessing the base station each time or waking up from a sleep state each time, or needs not to acquire the first system message frequently when reselecting to a target cell each time, thereby reducing the power consumption and the access delay of the user equipment.

In a possible implementation scheme, the first indication information includes a message identifier, where the message identifier is used to indicate a message in the first system message that is changed, or the message identifier is used to indicate a message in the first system message that the user equipment skips. The user equipment re-acquires the message indicated by the message identifier when reselecting to the second cell, and/or skips the message in the first system message except the message indicated by the message identifier, or skips the message indicated by the message identifier when reselecting to the second cell.

The user equipment can determine the message according to the message identifier, at this time, the user equipment can skip the message except the message in the first system message, or the user equipment can skip the message, so that the problem that the power consumption of the user equipment is high because the user equipment needs to acquire all the messages in the first system message again when the message is not specified is solved, and the power consumption and the access delay of the user equipment are reduced.

In one possible implementation, the method further includes: the user equipment receives second indication information sent by the first network equipment, wherein the second indication information is used for indicating a second cell with changed first system information, or the second indication information is used for indicating a second cell for skipping the first system information; wherein the second indication information comprises a cell identifier of the second cell; or the second indication information includes N bits, each bit corresponds to a second cell in the second cell list, and the bit corresponding to the second cell is used to indicate that the first system message is changed, or the bit corresponding to the second cell is used to indicate that the user equipment can skip the first system message; and the user equipment determines a second cell of the first system message, which is indicated by the second indication information, changes, or determines a second cell of the first system message, which is indicated by the second indication information, is jumped.

The user equipment can determine the second cell according to the second indication information, so that the problem that when the second cell is not specified, the user equipment needs to acquire the first system messages of all the second cells in the second cell list again, the power consumption of the user equipment is high is solved, and the power consumption and the access delay of the user equipment are reduced.

In a possible implementation scheme, the second indication information is carried in SIB1-BR or SIB4 or SIB5, and at this time, the receiving, by the ue, the second indication information sent by the first network device includes: when the second indication information is carried in a system information block 1-bandwidth reduction SIB1-BR of the first cell, the user equipment receives the SIB1-BR sent by the first network equipment again, and reads the second indication information from the SIB 1-BR; when the second indication information is carried in the SIB4, the user equipment receives the SIB4 sent by the first network equipment again, and reads the second indication information from the SIB 4; when the second indication information is carried in the SIB5, the user equipment receives the SIB5 sent by the first network equipment again, and reads the second indication information from the SIB 5.

In one possible implementation, the user equipment stores therein a first system message. If the user equipment stores the first system message of the first cell, when the user equipment finds that the first system message is changed or cannot jump, the first system message is obtained again, and otherwise, the first system message is jumped. If the user equipment stores the first system message of the second cell, when the user equipment reselects the second cell and finds that the first system message is changed or cannot be subjected to skip reading, the first system message is obtained again, and otherwise, the first system message is subjected to skip reading.

The non-volatile memory may also be an optical disc.

Referring to fig. 3, a flowchart of a method for acquiring and indicating a system message according to an embodiment of the present invention is shown. The system message acquiring and indicating method may include:

step 301, the first network device determines first indication information corresponding to the first system message.

The "correspondence" indicates that the first indication information is information related to the first system message.

The first network device may be a base station shown in fig. 1, or may also be a CU and a DU shown in fig. 1, which is not limited in this embodiment.

Step 302, the first network device sends first indication information to the user equipment.

Step 303, the user equipment receives first indication information sent by a first network device corresponding to the first cell.

The "correspondence" indicates that the network device formed the cell by transmitting a particular signal.

And step 304, the user equipment skips the first system message according to the first indication information, or reacquires the first system message according to the first indication information.

Here, skip is a meaning of not reading.

In summary, in the method for acquiring and indicating system messages provided in the embodiments of the present invention, the ue determines whether to skip the first system message or to reacquire the first system message according to the first indication information sent by the first network device, without frequently acquiring the first system message each time the ue is accessed or wakes up from a sleep state, or without frequently acquiring the first system message each time the ue reselects the target cell, so that power consumption and access delay of the ue are reduced.

The first system message may be a system message of a first cell, or may be a system message of a second cell adjacent to the first cell, where the first cell corresponds to the first network device, and the two methods for acquiring and indicating the first system message are described below.

Referring to fig. 4, a flowchart of a method for acquiring and indicating a system message according to an embodiment of the present invention is shown. If the first system message is a system message of the first cell, the method for acquiring and indicating the system message may include:

step 401, a first network device determines first indication information corresponding to a first system message, where the first system message is a system message of a first cell, and the first cell corresponds to the first network device.

The first cell may be a current serving cell of the user equipment.

The first indication information is used for indicating the user equipment to skip the first system information, or the first indication information is used for indicating the user equipment to reacquire the first system information.

Step 402, the first network device sends first indication information to the user equipment.

Optionally, the sending duration of the first indication information is N cycles, where the cycle is a Modified Period (MP) or a Discontinuous Reception (DRX) cycle or an enhanced DRX (eDRX) cycle; optionally, the first system message is unchanged in N periods; optionally, a result of a modulo operation of the initial system frame number sent by the first indication information on N periods is 0.

In the related art, when the first system message of the first cell changes, the first network device sets the first indication information to 1, and starts a Timer, and if the duration of the Timer is X hours, that is, the duration of the first indication information set to 1 is X hours, when the Timer times out, the first network device sets the first indication information to 0, please refer to fig. 5. When the first system message of the first cell changes again within X hours, the first network device restarts the timer when the first system message changes again, the duration of the timer is still X hours, and when the timer times out, the first network device sets the first indication information to 0, please refer to fig. 6. If the ue performs the sleep state after acquiring the first system message within X hours and wakes up from the sleep state within X hours, the ue needs to re-read the first system message when waking up, which results in that the ue acquires the same first system message for multiple times, and power consumption is high.

In the prior art, the first system message is not changed in a modification period, but only changed at the boundary of the modification period, as shown in fig. 7, the first cell sends the original first system message in MP (n), sends the updated first system message in MP (n +1), and then sends the updated first system message. The modification period duration is m, and meets the requirement that SFN mod m is 0, wherein SFN is a system frame number, the range is 0-1023, the notation is simple, and m is a positive integer. Thus, the boundary of the modification period is known to the ue, for example, m is 256, and the first system message may change when SFN is 0, 256, 512, 768.

In this embodiment, X hours may be set to N cycles (Period), which is denoted as NP, that is, the length of N cycles, that is, first indication information indicating that the first system message is changed (or not skipped) is sent within the duration of NP, for example, the first indication information indicating that the first system message is changed (or not skipped) is set to "1", and conversely, the first indication information indicating that the first system message is not changed (or skipped) is set to "0"; the meanings of "1" and "0" are interchangeable. Alternatively, the first indication information starts to transmit "1" at the SFN satisfying SFN mod NP being 0, and transmits "1" in M periods, where "1" indicates that the first system message is changed or not skipped, and "0" indicates that the first system message is not changed or skipped, or the meanings of "0" and "1" are interchanged, so that the user equipment knows the start time and the end time when the first indication information is set to "1". Since the first system message is updated very infrequently, the first cell may be restricted from the first system message changing within the NP. In this way, the user equipment only needs to read the first system message once in one NP, and in the NP after the NP ending boundary, the user equipment only needs to check the first indication information, if the first indication information is "1", the user equipment reads the first system message again, and if the first indication information is "0", the user equipment does not acquire the first system message again. The user equipment only needs to read the first system message once in one NP, so that the power consumption of the user equipment is saved.

It should be noted that, if the first system message needs to be updated, the first cell sends a paging message at an MP before the MP that starts sending the updated first system message, where the paging message carries update indication information to indicate that the first system message of the ue is about to be sent and changed, so that all ues need to reacquire the first system message from the next MP.

In this embodiment, the first indication information is carried in DCI of a paging message, or the MIB of the first cell or the MIB of the second cell.

Step 403, the user equipment receives first indication information sent by a first network device corresponding to the first cell.

It should be noted that the user equipment stores the first system message at this time, and when the storage time of the first system message does not exceed the preset time length, the first system message is valid, and then, when the first indication information is received and used for indicating the user equipment to reacquire the first system message, the user equipment deletes the stored first system message. The first system message is invalid when the storage time of the first system message exceeds a preset time. The preset time period may be 24 hours, or may be other time periods, which is not limited in this embodiment.

And step 404, the user equipment skips the first system message according to the first indication information, or reacquires the first system message according to the first indication information.

Please refer to fig. 8, which shows a flowchart of a method for acquiring and indicating a system message according to an embodiment of the present invention. If the first system message is a system message of a second cell adjacent to the first cell, the method for acquiring and indicating the system message may include:

step 801, a first network device determines first indication information corresponding to a first system message, where the first system message is a system message of a second cell adjacent to a first cell, and the first cell corresponds to the first network device.

The corresponding explanation is detailed in the description of the embodiment shown in fig. 3 and fig. 4, and is not repeated herein.

Before the user equipment reselects a second cell, the first cell is a current service cell of the user equipment, and the second cell is a neighbor cell of the first cell; after the user equipment reselects to the second cell, the second cell is the current serving cell of the user equipment.

When determining first indication information corresponding to a first system message, a first network device first receives a first message sent by a second network device; and determining the first indication information according to the first message. The first message is a first system message or a first message used for indicating whether the first system message is changed or the first message is used for indicating whether to skip the first system message, and the second network device corresponds to the second cell.

When the first message is the first system message, the first network device reads the stored latest first system message, compares the received first system message with the stored first system message, generates first indication information for indicating the user equipment to reacquire the first system message when the user equipment reselects the second cell when the received first system message is different from the stored first system message, and generates first indication information for indicating the user equipment to skip the first system message when the user equipment reselects the second cell when the received first system message is the same as the stored first system message.

When the first message is used for indicating whether the first system message is changed, the first network equipment generates first indication information for indicating whether the first system message is changed; when the first message is used for indicating whether to skip the first system message, the first network equipment generates first indication information for indicating whether to skip the first system message according to the first message.

The first indication information is carried in DCI of paging message or MIB of first cell or MIB of second cell. Taking the example that the first indication information is carried in the MIB of the first cell, the first network device may set a value of one bit in the MIB to "1" when generating the first indication information for indicating that the first system message is changed or for indicating that the user equipment is prohibited from skipping the first system message, and may set a value of one bit in the MIB to "0" when generating the first indication information for indicating that the first system message is not changed or for indicating that the user equipment is prohibited from skipping the first system message. The meanings of 1 and 0 may be interchanged, or the value of the bit in the MIB may be set to other values, which is not limited in this embodiment.

When a change occurs in the first system message of the second cell, the first network device may indicate the change in the second system message of the first cell, which may cause a change in the second system message. When the second system message of the first cell changes, the first cell is caused to send a paging message, and since the paging message instructs the ue to acquire the second system message, all ues need to acquire the second system message again. When the first indication information is carried in the MIB of the first cell, the user equipment may acquire the first indication information. That is, when the first indication information is carried in the MIB and the first indication information is used to indicate whether the first system message is changed or the first indication information is used to indicate whether the user equipment skips the first system message, the change of the MIB caused by the change of the first indication information triggers paging.

Step 802, a first network device sends first indication information to a user device.

Optionally, the sending duration of the first indication information is N cycles, where the cycle is a modification cycle or a DRX cycle or an eDRX cycle; optionally, the first system message is unchanged in N periods; optionally, a result of a modulo operation of the initial system frame number sent by the first indication information on N periods is 0.

The explanation of the sending duration is detailed in the description of the embodiment corresponding to fig. 4, and is not described herein again.

In this embodiment, the ue stores the first system message, and the storage time of the first system message does not exceed the preset time duration. If the user equipment does not store the first system message, the user equipment does not pay attention to the change of the first system message; if the first system message is stored for more than a predetermined length of time, the first system message is invalid and such user equipment may be considered as user equipment that does not store the first system message.

Step 803, the user equipment receives first indication information sent by a first network device corresponding to the first cell.

It should be noted that the user equipment stores the first system message. If the user equipment stores the first system message of the first cell, when the user equipment finds that the first system message is changed or cannot jump, the first system message is obtained again, and otherwise, the first system message is jumped. If the user equipment stores the first system message of the second cell, when the user equipment reselects the second cell and finds that the first system message is changed or cannot be subjected to skip reading, the first system message is obtained again, and otherwise, the first system message is subjected to skip reading.

When the storage time of the first system message does not exceed the preset time length, the first system message is valid, and then, when the first indication information is received and used for indicating the user equipment to reacquire the first system message, the user equipment deletes the stored first system message.

Step 804, the user equipment reads the first system message when reselecting the second cell according to the first indication information, or reacquires the first system message when reselecting the second cell according to the first indication information.

The skipping of the first system message when the user equipment reselects the second cell according to the first indication information, or reacquiring the first system message when the user equipment reselects the second cell according to the first indication information, includes:

alternatively, the first and second electrodes may be,

In summary, in the system message obtaining and indicating method provided in the embodiment of the present invention, when the first indication information indicates that the first system message changes or indicates the user equipment to re-obtain the first system message, the user equipment re-obtains the first system message, so that accuracy of the first system message stored in the user equipment is ensured; when the first indication information indicates that the first system message is not changed or indicates the user equipment to skip the first system message, the user equipment skips the first system message, and power consumption and access delay of the user equipment are reduced.

Based on the corresponding embodiment of fig. 8, the following implementation schemes may also be extended:

the first indication information and the first indication information comprise message identifications, at this time, the first network equipment determines the message identifications according to the first indication information, and the message identifications are used for indicating changed messages in the first system messages, or the message identifications are used for indicating messages read by the user equipment in the first system messages; the first network equipment sends first indication information to the user equipment, wherein the first indication information is used for indicating that the user equipment reacquires the message indicated by the message identification and/or skips the message in the first system message except the message indicated by the message identification when reselecting the second cell, or the first indication information is used for indicating that the user equipment skips the message indicated by the message identification when reselecting the second cell.

For example, when the SIB1-BR in the first system message is changed, the message identifier of the SIB1-BR may be added to the first indication information to indicate that the user equipment reacquires the SIB1-BR and/or skips messages other than the SIB1-BR when reselecting to the second cell; when the SIB1-BR in the first system message is not changed, the message identification of SIB1-BR can also be added to the first indication information to indicate that the SIB1-BR is skipped when the user equipment reselects to the second cell.

Correspondingly, the first indication information includes a message identifier, where the message identifier is used to indicate a message that is changed in the first system message, or the message identifier is used to indicate a message that the user equipment skips in the first system message, and then the user equipment reacquires the message indicated by the message identifier when reselecting to the second cell, and/or skips a message that is not indicated by the message identifier in the first system message, or the message indicated by the skips in the message identifier when reselecting to the second cell.

For example, when the first indication information includes the message identification of the SIB1-BR, the user equipment reacquires the SIB1-BR and/or skips messages other than the SIB1-BR when reselecting to the second cell; alternatively, the user equipment skips the SIB1-BR when reselecting to the second cell.

Second, the method further comprises: the first network equipment sends second indication information to the user equipment, wherein the second indication information is used for indicating a second cell with changed first system information, or the second indication information is used for indicating a second cell for skipping the first system information; wherein the second indication information comprises a cell identifier of the second cell; or the second indication information includes N bits, each bit corresponds to a second cell in the second cell list, and the bit corresponding to the second cell is used to indicate that the first system message is changed, or the bit corresponding to the second cell is used to indicate the user equipment to skip the first system message.

The N bits may be referred to as a bitmap.

The second cell list is provided by SIB4 and SIB5 of the first cell, SIB4 contains the co-frequency second cell list, 16 at most, SIB5 contains the inter-frequency second cell list, 16 at most, such that the bitmap is 32 bits at most, each bit corresponding to a second cell in the second cell list. And when a certain bit is 1, indicating that the first system message of the corresponding second cell is changed or indicating that the user equipment prohibits to skip the first system message, and when the certain bit is 0, indicating that the first system message of the corresponding second cell is not changed or indicating that the user equipment skips the first system message.

Wherein the second indication information is carried in SIB1-BR or SIB4 or SIB5 of the first cell.

Correspondingly, the method further comprises the following steps: the user equipment receives second indication information sent by the first network equipment, wherein the second indication information is used for indicating a second cell with changed first system information, or the second indication information is used for indicating a second cell for skipping the first system information; wherein the second indication information comprises a cell identifier of the second cell; or the second indication information includes N bits, each bit corresponds to a second cell in the second cell list, and the bit corresponding to the second cell is used to indicate that the first system message is changed, or the bit corresponding to the second cell is used to indicate that the user equipment can skip the first system message; and the user equipment determines a second cell of the first system message, which is indicated by the second indication information, changes, or determines a second cell of the first system message, which is indicated by the second indication information, is jumped.

Wherein the second indication information is carried in SIB1-BR or SIB4 or SIB5, and at this time, the ue receives the second indication information sent by the first network device, including: when the second indication information is carried in the SIB1-BR of the first cell, the user equipment receives the SIB1-BR sent by the first network equipment again, and reads the second indication information from the SIB 1-BR; when the second indication information is carried in the SIB4, the user equipment receives the SIB4 sent by the first network equipment again, and reads the second indication information from the SIB 4; when the second indication information is carried in the SIB5, the user equipment receives the SIB5 sent by the first network equipment again, and reads the second indication information from the SIB 5.

Thirdly, the first indication information is used to indicate whether the second system message of the first cell is changed or not, or the first indication information is used to indicate whether to skip the second system message of the first cell or not. That is, the first indication information may indicate that the first system message and/or the second system message are changed, or the first indication information may indicate that neither the first system message nor the second system message are changed; alternatively, the first indication information may indicate the user equipment to skip the first system message and the second system message, or the first indication information may indicate the user equipment to skip the first system message or the second system message.

At this time, the method further includes: the first network equipment determines whether the second system information is changed; when the user equipment determines that neither the first system information nor the second system information indicated by the first indication information has changed, skipping the second system information (for example, SIB1-BR) of the first cell; or when the second cell is reselected, skipping the first system message of the second cell; or, when determining that the first system information or the second system information indicated by the first indication information changes, the user equipment reacquires the second system information of the first cell; or, when reselecting the second cell, reacquiring the first system message of the second cell; and when the second system message contains second indication information, determining a second cell according to the second indication information, reselecting the second cell, and reacquiring the first system message when determining that the first system message indicated by the first indication information is changed. The definition of the second indication information is described in detail in the above description, and is not described again here.

For example, the user equipment may determine whether the first system message or the second system message is changed by reading the SIB1-BR, and determine which second cell's first system message is changed when the first system message is changed.

Fourthly, the ue may also skip the MIB of the second cell, and at this time, the method further includes:
