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 obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. example. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

An embodiment of the present invention provides a sending method, as shown in FIG. 1 , including:

Step 11: Set an indication of discontinuous reception of a DRX cycle type, where the cycle type includes a DRX long cycle and a DRX short cycle, and the indication of setting the DRX cycle type is included in a Medium Access Control Cell (MCE) identifier. The corresponding load is increased by at least 1 bit to indicate a DRX long period, or a new MCE indicator is set to indicate a DTX long period.

For example, the embodiment of the present application utilizes some existing MCE beacons in the current 3GPP protocol. In the case of the unrecognized load, the load corresponding to the MCE identifier is increased by at least 1 bit to indicate the entry into the DRX long period. The embodiment of the present invention is described by 8 bits (ie, 1 character), and two characters may be added to the payload. (16 bits) or more characters (32 bits) or the like indicates whether the terminal is to enter the DRX long period or the DRX short period. In the case where the DRX long period and the DRX short period are simultaneously configured, the terminal can directly enter the DRX long period according to the instruction of adding at least one bit.

The DRX long period is indicated by any one of the 8 bits. For example, the payload corresponding to the MCE identifier 1 1110 may be increased by 8 bits, and the first seven bits may be set to 0 and/or 1, and the last bit of the added 8-bit payload may be set to 0 or 1 for Identify DRX long periods.

For example, the payload corresponding to the MCE identifier may be increased by 8 bits, and the last 1 bit may be set to 0 to indicate that the terminal enters the DRX long period, or may be set to 1 to indicate that the terminal enters the DRX long period; The number of bits can be set to 0; if you need to configure the DRX long period, you can set the increased 8-bit payload to 00000001.

For example, after the base station negotiates with the terminal, the last bit of the 16-bit payload added to the MCE identifier may be set to 1 to indicate that the terminal enters the DRX long period; if the DRX long period needs to be configured, The increased 16-bit load can be set to 10011 1001001 1110, or it can be set to 01101 11000001000 and so on.

Further, the embodiment of the present invention may select one MCE identifier in the MCE identifier that is reserved but not used in the current 3GPP protocol as the new MCE identifier, and instruct the terminal to enter the DRX long period, so that the DRX long period and the DRX are simultaneously configured. In the case of a short period, it is possible to directly enter the DRX long period according to the indication of the identification.

Specifically, any one of the identifiers that are reserved but not used in the current 3GPP protocol is selected to indicate that the terminal enters the DRX long period. For example, after the base station negotiates with the terminal, the identifier 0101 1 is used to indicate that the terminal enters the DRX length. If the DRX long period needs to be configured, the identifier 0101 1 is sent to the terminal.

Step 12: Send the set indication of the DRX cycle type to the terminal.

Setting the DRX cycle type by setting an indication of discontinuous reception of the DRX cycle type The indication includes adding at least 1 bit to the payload corresponding to the MCE identifier of the medium access control cell, or setting a new MCE identifier, so that when the DRX long period and the DRX short period are simultaneously configured, the DRX length can be directly entered according to the indication. The cycle, thereby improving the power saving effect of the terminal.

An embodiment of the present invention provides a sending apparatus, as shown in FIG. 2, including:

The setting unit 21 is configured to set an indication of a discontinuous reception DRX cycle type, where the cycle type includes a DRX long cycle and a DRX short cycle, and the indication of setting the DRX cycle type includes a media access control cell MCE identifier The corresponding load is increased by at least 1 bit to indicate the DRX long period, or a new MCE indicator is set to indicate the long period.

By setting an indication of the discontinuous reception of the DRX cycle type, the cycle type includes a DRX long cycle and a DRX short cycle, and the indication of setting the DRX cycle type includes adding at least one load corresponding to the media access control cell MCE identifier. The bit indicates the long period of the DRX, or the new MCE indicator is set to indicate the long period. In the case that the DRX long period and the DRX short period are simultaneously configured, the DRX long period can be directly entered according to the indication, thereby improving the power saving effect of the terminal.

Further, the setting unit is specifically configured to add 8 bits to the load corresponding to the MCE identifier, set the first 7 bits of the added 8 bits to 0 and/or 1, and set the last 1 bit to 0 or 1. For indicating the DRX long period; or the setting unit is specifically configured to select any one of the original MCE identifiers 01011 to 1 1011 as a new MCE identifier, and is used to indicate the DRX long period.

In the embodiment of the present application, the load corresponding to the MCE identifier in the 3GPP protocol is increased by 8 bits (that is, 1 character) to indicate that the terminal needs to enter the DRX long period, so that when the DRX long period and the DRX short period are simultaneously configured, according to the added The bit decides to enter the DRX long cycle or the DRX short cycle.

The embodiment of the present invention is described by taking one character as an example. It is also possible to add two characters (16 bits) or more characters (32 bits, etc.) to the payload to indicate that the terminal is to enter the DRX long period, and details are not described herein again. Further, in the embodiment of the present application, one MCE identifier of the MCE identifier that is reserved but not used in the 3GPP protocol is selected as a new MCE identifier, which is used to indicate that the terminal enters the DRX long period, so that the DRX long period is configured at the same time. In the case of a short DRX cycle, the DRX long cycle can be directly entered according to the indication of the flag.

The specific implementation of the processing functions of the units included in the foregoing base station has been described in the previous method embodiments, and the description thereof will not be repeated.

In the embodiment of the present invention, when the bit of the corresponding payload of the existing MCE identifier is added or the new MCE identifier is added, the terminal is instructed to enter the DRX long period or the DRX short period, so that the DRX long period and the DRX short period are simultaneously configured. The DRX long cycle is directly entered according to the added bit or the new identifier, which improves the power saving effect of the terminal.

Since the DRX long period and the DRX short period are configured in different periods based on the current protocol, and the Radio Resource Control (RRC) is required to reconfigure the DRX long period or the DRX short period, the long DRX length is completed by switching between long and short periods. The periodic signaling configuration, but the frequent switching causes additional overhead and delay. The method provided by the embodiment of the present invention can directly enter the long period, avoiding switching back and forth to configure long DRX short-cycle signaling, and introducing additional overhead. Or time delay.

An embodiment of the present invention provides another sending method, as shown in FIG. 3, including:

Step 31: Receive an indication of a set DRX cycle type, where the cycle type includes a DRX long cycle and a DRX short cycle, and the indication of the set DRX cycle type includes adding at least 1 to a load corresponding to the media access control cell MCE identifier. The bits indicate the DRX long period, or set a new MCE indicator to indicate a long period.

Step 32: If the indication of the set DRX cycle type is that the payload corresponding to the MCE identifier is increased by at least 1 bit, enter a DRX long cycle according to the indication of the added bit.

Step 33: If the indication of the set DRX cycle type is to set a new MCE identifier, enter a DRX long cycle.

The above method may also adopt only the party that adds a new MCE identifier after the terminal negotiates with the base station. The method indicates that the terminal enters the DRX long period, or uses only the existing MCE identifier corresponding to the increased bit of the load to indicate that the terminal enters the DRX long period, so that when the DRX long period and the DRX short period are simultaneously configured, the DRX can be directly entered according to the indication. Long cycle, which improves the power saving effect of the terminal.

For example, if the terminal negotiates with the base station, the base station side only uses the method of adding a new MCE identifier to instruct the terminal to enter the DRX long period. The terminal only needs to determine whether the received identifier is an added new identifier. If yes, the DRX is entered. The period, if not, enters the DRX short period; for example: if the terminal negotiates with the base station, the base station side only uses the method that the existing MCE identifier corresponding load is increased by at least 1 bit to indicate that the terminal enters the DRX long period, the terminal only needs to judge Whether the received MCE identifier corresponds to whether the load is increased by a bit, and if so, enters the DRX long period or the DRX short period according to the indication of the load, and if not, the adjustment is not performed.

Further, the embodiment of the present application utilizes the current 3GPP protocol, where some existing MCE cell identifiers do not have a corresponding payload, and the payload corresponding to the MCE identifier is increased by 8 bits (ie, 1 character) to indicate that the terminal needs to enter the DRX long period. It is also a short cycle of DRX, so that when the DRX long cycle and the DRX short cycle are configured at the same time, the terminal can directly enter the long cycle according to the indication of the load.

The embodiment of the present invention is described by taking one character as an example. It is also possible to add two characters (16 bits) or more characters (32 bits, etc.) to the payload to indicate that the terminal wants to enter the DRX long period, and details are not described herein again.

Specifically, if the received MCE identifier is 1 1110, it is determined whether the identifier increases the bit of the corresponding payload, and if yes, the last one bit in the increased payload is set to 0 to indicate that the DRX short period is Set to 1 to indicate the DRX long period. For example, after the base station negotiates with the terminal, it determines that the last bit of the bit with the corresponding load increase is set to 0, indicating that the terminal enters the DRX short period, and is set to 1, indicating that the terminal enters the DRX long period. If the terminal receives the bit that increases the corresponding payload, which is 8 bits, specifically 00000001 or 011011, or enters the DRX long period, the * can be represented as any one of 0 or 1. If the terminal receives the number of bits that increase the corresponding load 16 bits, specifically 0000000000000001 or 1010101001 101 11 1 Or enter the _DRX long period, the * can be expressed as any one of 0 or 1. Further, the embodiment of the present application utilizes the MCE identifier that is reserved but not used in the current 3GPP protocol, and adopts one of the MCE identifiers as the new MCE identifier, indicating that the terminal enters the DRX long period, so that the terminal is configured at the same time. In the case of the DRX long cycle and the DRX short cycle, the long cycle can be directly entered according to the indication of the identification.

Specifically, the identifier of the current MCE identifier is between 01011 and 1101, and the identifier of the new MCE is any one of 01011 to 1 101 1 if the terminal receives the identifier of the new MCE sent by the base station. The terminal is instructed to enter the DRX long period. For example, after the terminal negotiates with the base station, it determines that 0101 1 indicates that the terminal enters the DRX long period. If the identifier received by the terminal is 01011, it is determined that it is the added new MCE identifier, and then directly enters the DRX length. Period; if the MCE identifier received by the terminal is other than 0101 1, it enters the DRX short period.

The embodiment of the present invention provides another method for transmitting, in which the terminal is instructed to enter the DRX long period or the DRX short period by using a method of adding a new MCE identifier, and the base station negotiates with the terminal to determine that the added new MCE identifier is 10001. (Alternatively, any one of the identifiers between 0101 1 and 1 1011 can be selected), as shown in Figure 4, including:

401. Add a new identifier to the base station. The 10001 is used to instruct the terminal to enter the DRX long period.

402. If the base station commands the terminal to enter the DRX long period at the next moment, the new identifier 10001 is sent to the terminal.

403. After receiving the new identifier 10001, the terminal enters a DRX long period at the next moment.

Further, if the terminal does not receive the new identifier 10001, the terminal continues to execute the existing command.

The embodiment of the present invention further provides a sending method, which uses the method of adding at least one bit of the existing identifier to increase the DRX long period, and the base station and the terminal negotiate to determine that the corresponding load of the identifier 111 10 is increased by 8 bits, and is used for indicating The DRX cycle type of the terminal, as shown in Figure 5, includes: 501. The base station negotiates with the terminal to increase the load corresponding to the MCE identifier by adding at least 1 bit, and sets the last bit to 0, indicating that the terminal enters the DRX long period, and is set to 1, indicating that the terminal enters the DRX short period. The remaining 7 bits can be set arbitrarily.

If the base station wants to command the terminal to enter the DRX short cycle at the next moment, the base station will identify 1 1110 and its corresponding payload 10101010 (you can also select *******0, where "*" can select any 1 of 1 or 0. ) is sent to the terminal.

502. The base station sends the terminal to the terminal that increases the load corresponding to the set MCE identifier.

503. The terminal enters a D RX long period according to the indication of the received bit.

For example, the identifier 11 110 and its corresponding payload 10101010 enter the DRX long period at the next moment. Further, if the terminal does not receive the identifier 1 11 10 or receives the identifier 111 10 but does not receive the corresponding payload, the terminal continues to execute the existing command; if the terminal receives the identifier 1 11 10 and its corresponding payload, Enter the DRX short cycle at the next moment. An embodiment of the present invention further provides another sending apparatus, as shown in FIG. 6, including:

The receiving module 61 is configured to receive an indication of the set discontinuity receiving DRX cycle type, where the indication of the set DRX cycle type includes adding at least one bit to the long period of the media access control cell MCE identifier, or Set a new MCE indicator to indicate a long period.

The processing module 62 is configured to enter a DRX long period when the indication of the DRX period type received by the receiving module is to set a new MCE identifier, or an indication of the DRX period type received by the receiving module Adding at least 1 bit to the load corresponding to the MCE identifier indicates entering the long period, and then entering the DRX long period according to the indication of the added bit.

The specific implementation of the processing functions of the modules included in the foregoing terminals has been described in the previous method embodiments, and the description thereof will not be repeated.

By setting an indication of the discontinuous reception of the DRX cycle type, the cycle type includes a DRX long cycle and a DRX short cycle, and the indication of setting the DRX cycle type includes adding at least one load corresponding to the media access control cell MCE identifier. Bit, or set a new MCE identifier, so When the DRX long period and the DRX short period are configured at the same time, the DRX long period can be directly entered according to the indication, thereby improving the power saving effect of the terminal. The method of the embodiment of the present invention is adopted because the DRX long period and the DRX short period are configured at different times according to the current protocol, and when the RRC reconfiguration DRX long period or the DRX short period is required, which is completed by the interaction of signaling in the long and short periods. In the case where the DRX long period and the DRX short period are not configured at the same time, the signaling of configuring the long DRX short period to switch back and forth is avoided, and additional overhead or delay is introduced.
