Description
Technical Field

Background
Currently, a service area of a mobile communication is an area covered by a plurality of cells of a base station, and is used for communicating with an Access Terminal (AT). Each cell comprises a plurality of sectors, a set of the sectors which establish connection with the access terminal is called an active set corresponding to the access terminal, the sector which performs data transmission service with the access terminal is a service sector, and the service sector of the access terminal belongs to the active set corresponding to the access terminal.
The access terminal receives the Data rate control locking Bit (English: Data RateCtrl Lock Bit, DRCLock Bit) value fed back by each sector in the active set, selects one sector from the sectors with the DRCLock Bit value of 1 as the service sector, and sends the identifier of the current service sector to each sector in the active set. When the DRCLock Bit values received by the access terminal are all 0, the access terminal selects a non-serving sector, and needs to wait at least until the next DRCLock change slot, the access terminal may reselect a sector with a transmitted DRCLock Bit value of 1 from the active set as a serving sector, and continues the data transmission service using the reselected serving sector.
When the service sector and the access terminal perform data transmission service, the access terminal cannot select the service sector due to unstable signals of all sectors in the active set, and the service sector can be selected to perform data transmission service only after the next DRCLock change time slot, which results in delay of data transmission service recovery.

In summary, in the method for selecting a serving sector according to the embodiment of the present invention, by receiving an indication parameter sent by each sector in an active set, where the indication parameter sent by each sector is used to indicate a channel quality of an uplink channel used by an access terminal to send data to the sector, and when a value of the indication parameter sent by each sector indicates that a channel quality of a corresponding uplink channel is poor, notifying each sector in the active set that the serving sector of the access terminal is unchanged; when the values of the indicating parameters sent by the sectors indicate that the channel quality of the corresponding uplink channel is poor, the access terminal informs the sectors in the active set that the service sector of the access terminal is unchanged, and the data transmission service can be immediately continued when the signal of the service sector is recovered, so that the technical problem that the recovery of the data transmission service is delayed when the signal of each sector in the active set is unstable in the related art is solved, and the effect of improving the transmission efficiency of the data transmission service is achieved.
Referring to fig. 4A, a flowchart of a serving sector selection method according to another exemplary embodiment of the present invention is shown, where the serving sector selection method includes the following steps.
Step 401, each sector in the active set sends an indication parameter to the access terminal according to the sending period of the indication parameter, and the indication parameter sent by each sector is used for indicating the channel quality of an uplink channel used by the access terminal to send data to the sector.
The transmission period of the indication parameter is referred to herein as a minimum time interval in which the indication parameter value transmitted by the sector to the access terminal changes.
The value of the indication parameter sent by the sector to the access terminal is unchanged in one sending period of the indication parameter. For example, the transmission period of the indication parameter is 512 time slots (Slot), and when a sector in the active set detects that the channel quality of the uplink channel used by the access terminal to transmit data to the sector is good at Slot0, the sector transmits the indication parameter for indicating that the channel quality of the uplink channel used by the access terminal to transmit data to the sector is good to the access terminal between Slot0 and Slot 511. Even if the channel quality of the uplink channel used by the access terminal to transmit data to the sector is poor between Slot 400 and Slot 511, the sector still transmits to the access terminal an indication parameter indicating that the channel quality of the uplink channel used by the access terminal to transmit data to the sector is good. The value of one Slot may be set according to an actual situation, for example, 1s or 5s, and the value of one Slot is not limited in this embodiment.
In the next transmission period of the indication parameter, the sector detects the channel quality of an uplink channel used by the access terminal for transmitting data to the sector at the starting time of the next transmission period, and transmits the corresponding value of the indication parameter in the next transmission period according to the detected channel quality.
Optionally, the indication parameter is DRCLock, and when the value of DRCLock sent by the sector is the first value, the indication parameter is used to indicate that the channel quality of the uplink channel between the access terminal and the sector is good; when the value of the DRCLock sent by the sector is the second value, the indication parameter is used to indicate that the channel quality of the uplink channel between the access terminal and the sector is poor.
The first value and the second value are different values, for example, the first value of DRCLock may be 1, and the second value of DRCLock may be 0. For another example, the first value of DRCLock may be GOOD, and the second value of DRCLock may be BAD. In this embodiment, neither the type nor the value of the first value nor the second value is specifically limited, and may be set according to an actual situation.
For example, the transmission period of the DRCLock is 512 slots, and when a sector in the active set detects a channel quality difference of an uplink channel between the access terminal and the sector at the time of Slot 512, DRCLock values sent by the sector to the access terminal in slots 512 to 1023 are all 0. Even if the channel quality of the uplink channel between the access terminal and the sector becomes good between Slot600 to Slot1023, the DRCLock value sent by the sector to the access terminal between Slot600 to Slot1023 is still 0.
It should be noted that the transmission periods of the indication parameters transmitted by the sectors in the active set are the same, and the indication parameters are transmitted by the sectors in the active set at the same time.
In step 402, the access terminal receives indication parameters sent by each sector in the active set.
Because the sending periods of the indication parameters sent by all the sectors in the active set are the same, and all the sectors in the active set send the indication parameters at the same time. Accordingly, the access terminal may receive the indication parameters transmitted by the sectors in the active set at the same time.
Step 403, when the values of the indication parameters sent by each sector indicate that the channel quality of the corresponding uplink channel is poor, the access terminal notifies each sector in the active set that the serving sector of the access terminal is unchanged.
Because the active set has a plurality of sectors connected with the access terminal, the channel quality of an uplink channel between the access terminal and one of the sectors is better in a certain period of time, and at the moment, the access terminal can take the sector as a service sector; however, at another time, the channel quality of the uplink channel between the access terminal and the sector may be degraded, and in order to efficiently transmit data of the access terminal, the access terminal needs to switch the serving sector to another sector in the active set. Therefore, in order to enable the access terminal to better select a serving sector with better transmission efficiency or transmission quality and avoid frequent switching of the serving sector by the access terminal, a period for switching the serving sector may be set for the access terminal.
Generally, the period of the access terminal switching the serving sector is the minimum time interval for the access terminal to switch the serving sector. That is, the access terminal may perform the selection of the serving sector once every predetermined time interval.
Generally, the period for switching the serving sector by the access terminal is less than the transmission period of the indication parameter, that is, the transmission period of the indication parameter is greater than the period for switching the serving sector by the access terminal. For example, the period for switching the service sector by the access terminal is 512 slots, and the period for switching the service sector by the access terminal is 8 slots.
Because the transmission period of the indication parameter is greater than the period of the access terminal for switching the serving sector, and when the values of the indication parameters transmitted by the access terminal in each sector indicate that the channel quality of the corresponding uplink channel is poor, it indicates that no suitable sector can be used as the serving sector of the access terminal at present, and it is usually necessary to wait until the starting time of the transmission period of the next indication parameter to obtain the latest indication parameter transmitted by the sector, so that the access terminal can reselect the serving sector according to the latest indication parameter. In practical applications, there may be a case where, before a transmission period of a next indication parameter, a channel quality of an uplink channel corresponding to each sector in an active set is improved, or a channel quality of an uplink channel corresponding to a last selected serving sector is improved, and in order to reduce a waiting time period, each sector in the active set may be notified that a serving sector of the access terminal is not changed, so that, once the channel quality of the uplink channel corresponding to the serving sector is improved, a data transmission service may be directly performed by using the serving sector.
Alternatively, informing the various sectors in the active set that the serving sector for the access terminal is unchanged may be accomplished through several substeps as shown in fig. 4B.
In step 403a, the access terminal obtains the serving sector identifier that the access terminal last sent to each sector in the active set, where the serving sector identifier is the identifier of the serving sector selected from the active set as the access terminal.
In step 403b, the access terminal sends the serving sector identity to each sector in the active set.
In this embodiment, the indication parameter is DRCLock, the first value of DRCLock is 1, and the second value of DRCLock is 0. Fig. 4C shows a schematic diagram for performing serving sector selection according to this embodiment, where an active set corresponding to an access terminal includes a first sector 41 and a second sector 42, where an identifier of the first sector 41 is a, an identifier of the second sector 42 is b, and other parameters are set as follows: the access terminal switching service sector period is 8 slots, and the transmission period of the DRCLock is 512 slots.
When the Slot0 is detected, the first sector 41 detects that the channel quality of the uplink channel used by the access terminal to transmit data to the first sector 41 is good, and the indication parameter DRCLock values transmitted by the first sector 41 to the access terminal are all 1 between the Slot0 and the Slot 511. When the channel quality of the uplink channel used by the access terminal to transmit data to the second sector 42 is good, detected by the second sector 42 in Slot0, the DRCLock value of the indication parameter transmitted by the second sector 42 to the access terminal is all 1 between Slot0 and Slot 511.
In Slot0, the access terminal receives that the DRCLock values sent by the first sector 41 and the second sector 42 are both 1, and then selects one sector from the first sector 41 and the second sector 42 as a serving sector according to other reference parameters. Other reference parameters referred to herein can be channel quality of a downlink channel on which the access terminal receives data from the sector, and can also be other parameters. The present embodiment is illustrated with the access terminal selecting the first sector 41 as the serving sector between Slot0 to Slot 399.
Between Slot0 to Slot399, the access terminal sends the identifier of the first sector to the first sector 41 and the second sector 42 in the form of a message of "Data Rate control sector (DRC Cover) ═ a", which informs the access network that Data transmission service can be performed through the first sector 41.
Between slots 400-600, the signal quality of the first sector 41 and the second sector 42 is poor, and the data transmission service between the access terminal and the first sector 41 is interrupted. In Slot 512, the first sector 41 detects that the channel quality of the uplink channel used by the access terminal to transmit data to the first sector 41 is poor, and in between Slot 512 to Slot1023, the indication parameter DRCLock value transmitted by the first sector 41 to the access terminal is 0. Similarly, in Slot 512, the second sector 42 detects that the channel quality of the uplink channel used by the access terminal to transmit data to the second sector 42 is poor, and in slots 512 to 1023, the indication parameter DRCLock value sent by the second sector 42 to the access terminal is 0. At Slot 400, data transmission traffic between serving sector 41 and the access terminal is interrupted due to poor signal quality of serving sector 41.
In Slot 512, the access terminal receives that the DRCLock values sent by the first sector 41 and the second sector 42 are both 0, and the access terminal obtains the serving sector identifier sent to each sector in the active set at the last time, where the serving sector identifier is the identifier a of the first sector 41. The identifier a of the first sector 41 is sent to the first sector 41 and the second sector 42 in the form of a "DRC Cover ═ a" message, so as to inform the access network that data transmission service can be performed through the first sector 41. So that data transmission traffic between the access terminal and the first sector 41 can be immediately recovered when the signal of the first sector 41 is recovered, such as at the Slot 600.
In step 404, if the quality of the uplink channel corresponding to the serving sector meets the condition for sending data before the access terminal receives the next set of indication parameters, the uplink channel is used to send data to the serving sector.
If the quality of the uplink channel corresponding to the serving sector of the access terminal meets the condition for sending data before the access terminal receives the next set of indication parameters, the access terminal can send data to the serving sector by using the uplink channel.
For example, still referring to fig. 4C, between Slot600 to Slot1023, the channel quality of the uplink channel corresponding to the first sector is good. In Slot600, the quality of the uplink channel corresponding to the first sector 41 meets the condition for transmitting data, and the access terminal may transmit data to the serving sector by using the uplink channel. It can be derived by a simple reasoning for a person skilled in the art that the data transmission traffic is interrupted by only 200 slots from Slot0 to Slot1023 (i.e. from Slot 400 to Slot 600).
When the quality of the uplink channel corresponding to the serving sector of the access terminal meets the condition of sending data, it indicates that the signal of the serving sector is better at this time, and not only the access terminal can send data to the serving sector by using the uplink channel, but also the access terminal can receive the data sent by the serving sector, that is, the access terminal can continue data transmission service through the serving sector.
In summary, in the method for selecting a serving sector according to the embodiment of the present invention, by receiving an indication parameter sent by each sector in an active set, where the indication parameter sent by each sector is used to indicate a channel quality of an uplink channel used by an access terminal to send data to the sector, and when a value of the indication parameter sent by each sector indicates that a channel quality of a corresponding uplink channel is poor, notifying each sector in the active set that the serving sector of the access terminal is unchanged; when the values of the indicating parameters sent by the sectors indicate that the channel quality of the corresponding uplink channel is poor, the access terminal informs the sectors in the active set that the service sector of the access terminal is unchanged, and the data transmission service can be immediately continued when the signal of the service sector is recovered, so that the technical problem that the recovery of the data transmission service is delayed when the signal of each sector in the active set is unstable in the related art is solved, and the effect of improving the transmission efficiency of the data transmission service is achieved.
At Slot 400, the data transmission traffic of the access terminal with the serving sector is interrupted. At Slot 512, the access terminal receives a DRCLock value of 0 for both the first sector 41 and the second sector 42. In the existing protocol, when the DRCLock values sent by the active set are all 0, the access terminal cannot select a serving sector, and the access network is notified in the form of a "DRC Cover ═ 0" message that the access terminal has no serving sector, and at this time, the data transmission service of the access terminal is still in the terminal state.
The signal quality of the first sector 41 and the second sector 42 is good between the slots 600 to 1024, and when the Slot1024 is detected, the channel quality of an uplink channel used by the access terminal to transmit data to the first sector 41 is good, and DRCLock transmitted by the first sector 41 to the access terminal is 1. Similarly, in Slot1024, the second sector 42 detects that the channel quality of the uplink channel used by the access terminal to transmit data to the second sector 42 is good, and the DRCLock transmitted by the second sector 42 to the access terminal is 1.
Accordingly, when the access terminal receives data transmission traffic in the Slot1024, the first sector 41 and the second sector 42 in the active set both transmit DRCLock 1, and one of the first sector 41 and the second sector 42 is selected as the serving sector to continue the interrupted data transmission traffic. It can be derived by a simple reasoning for a person skilled in the art that the data transmission traffic is interrupted by 624 slots between Slot0 and Slot 1024.
Obviously, the scheme in the embodiment can reduce the time length of data transmission service interruption to a greater extent.
