In the prior art, when the base station is self-starting, it needs to traverse these ²³¹ combinations, try to establish a link for each combination in turn, determine the successful combination as the time slot pattern configured by the base station control device, and then use the determined time slot pattern Gap pattern for link building. Since the time slot pattern may need to be polled for ²³¹ times, the self-starting link establishment time is too long, which cannot meet business requirements.

In the prior art, in order to reduce the link establishment time, a limited number of time slot patterns can be tried according to typical customer application scenarios, for example, 20 typical time slot patterns are selected, and only these 20 time slot patterns are tried after the base station starts up . However, it takes a long time to try these 20 time slot patterns, and, with different scenarios, the corresponding typical time slot patterns are also different. Using a fixed time slot pattern cannot cover all scenarios, and the scope of use is limited. limit.

Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Fig. 1 is a schematic flow chart of the first embodiment of the present invention, including:

Step 11: the base station obtains the initial time slot pattern of the Time Division Multiplexing (TDM) frame;

Wherein, the TDM frame may be an E1 frame, a T1 frame or a J1 frame;

In the PPP protocol scenario, the time slot pattern can be a combination of the time slots occupied by the PPP link information in the TDM frame; at the 64K time slot level (fractional) Asynchronous Transfer Mode (Asynchronous TransferMode, ATM) inverse multiplexing technology In the (Inverse Multiplexing for ATM, IMA) protocol scenario, it can be a combination of the time slots occupied by fractional IMA protocol information in the TDM frame; or, in the fractional IMA protocol scenario, the PPP link information is first used to detect the slot pattern in order to The time slot pattern obtained after detection includes transmission of fractional IMA protocol information in the time slot. At this time, the time slot pattern is also a combination of time slots occupied by the PPP link information in the TDM frame.

Step 12: The base station sends a first matching success indication message to the base station control device in each time slot corresponding to the initial time slot pattern, and the first matching success indication message includes the time slot number corresponding to the initial time slot pattern ;

Wherein, the base station can be a base transceiver station (Base Transceiver Station, BTS), and the base station control device is a base station control device (Base Station Controller, BSC); or, the base station is a NodeB, and the base station control device is a radio network controller (Radio Network Controller, RNC).

Step 13: After receiving the second matching indication message sent by the base station control device, the base station determines the initial time slot pattern as the time slot pattern to be configured by itself, and the second matching success indication message is the The base station control device sends it after comparing that the time slot number included in the first matching success indication message is the same as the time slot number configured by the base station control device.

In this embodiment, the configured time slot pattern is obtained directly through the information interaction between the base station and the base station control device, and does not need to be polled sequentially, nor does it only try a limited number of times, so the link establishment time can be reduced, and the scope of use is not limited.

FIG. 2 is a schematic flow chart of the second embodiment of the present invention. In this embodiment, the base station obtains an initial time slot pattern through a time slot occupancy instruction message sent by a base station control device as an example. This example includes:

Step 201: The base station sends the first time slot occupancy indication message (Inform) to the base station control device

Wherein, in the embodiment of the present invention, the base station does not perform the PPP link establishment negotiation after starting, but first determines the time slot pattern, and then initiates the PPP link establishment negotiation according to the determined time slot pattern.

In the embodiment of the present invention, a time slot occupancy indication message is newly added, which is used to notify the opposite end (for example, the base station control device) of the time slot configuration of the local end (for example, the base station). The format of the timeslot occupancy indication message may be as shown in FIG. 3 . Referring to Fig. 3, a newly defined value is adopted, such as 0x00F1 (represented as 00F1 in Fig. 3) to show that the message is a time slot occupancy indication message, and the time slot occupancy indication message also contains the time slot number of the local end, Such as 01~1F.

It can be understood that since the base station does not know the time slot pattern configuration after self-starting, in this embodiment, after self-starting, the base station will send time slot occupancy indication messages on all time slots, and each time slot The time slot number of the occupancy indication message is set to a value indicated as null (Null).

Step 202: After receiving the first time slot occupation indication message sent by the base station, the base station control device sends the second time slot occupation indication message to the base station.

Wherein, in the embodiment of the present invention, the base station control device is used to configure the time slot pattern of the PPP information in the E1 frame. Therefore, the base station control device will know the time slot pattern. After that, the base station control device can notify the user through the time slot occupation indication message base station.

For example, the time slot pattern configured by the base station control equipment is: PPP link information is sent in the 2nd, 4th, and 6th time slots of the E1 frame, and the base station controller will Slot occupancy indication messages are sent in the slots respectively, and carry slot numbers 2, 4, and 6 respectively.

After the base station receives the second time slot occupancy instruction message (the second inform message), it obtains the time slot pattern configured by the base station control device, and determines the time slot pattern configured by the base station control device as the initial time slot pattern, that is, the first The time slot number contained in the second time slot occupancy indication message is determined to be the time slot number corresponding to the initial time slot pattern.

Step 203: the base station sends a first matching success indication message (ACK) to the base station control device in each time slot corresponding to the initial time slot pattern.

For example, when the time slot numbers carried in the second time slot configuration indication message are 2, 4, and 6 respectively, the base station can know that the time slot pattern configured by the base station control device is at the 2nd, 4th, and 6th time slots of the E1 frame. Send PPP link information in the slot. Afterwards, the base station may send ACK messages in the 2nd, 4th, and 6th time slots respectively, and the ACK message sent at this time is called the first ACK message.

The ACK message is a newly added message in the embodiment of the present invention. The first ACK message is because the base station has no time slot configuration before, and the base station obtains the time slot configuration according to the second time slot configuration indication message sent by the base station control device. After that, send it directly.

The format of the ACK message may be as shown in FIG. 4 . Referring to Figure 4, a newly defined value, such as 0x00F2 (shown as 00F2 in Figure 4), indicates that the message is a successful match indication message, and the successful match indication message also contains the time slot number of the local end, such as 01 ~1F. For example, the time slot numbers obtained by the base station are 2, 4, and 6 respectively, then the base station sends matching success indication messages in the 2nd, 4th, and 6th time slots of the E1 frame sent respectively, and carry the time slot numbers 2, 4, and 6 respectively. 4,6.

Step 204: After receiving the first matching success indication message, the base station control device compares the time slot pattern indicated by the first matching success indication message with the time slot pattern configured by itself, and when the two are the same, sends the second matching success indication message to the base station. instruction message.

The second matching success indication message is sent when the time slot configuration of the opposite end is the same as that of the local end, and its format is the same as that of the first matching success indication message. Refer to FIG. 4 for details.

For example, the above-mentioned first matching success message indicates that the time slot numbers corresponding to the time slot patterns are 2, 4, and 6 respectively, and the time slot numbers corresponding to the time slot patterns configured by the base station control device are also 2, 4, and 6 respectively. , since the two are the same, the base station control device sends the second ACK message to the base station.

In addition, for the base station or base station control equipment, after receiving the first time slot occupancy indication message, the local end can start the set timer, and collect the time slot occupancy indication message sent by the other end within the timer time. file to determine the time slot configuration of the peer end. Moreover, after receiving the matching success indication message sent by the opposite end, the time slot occupation indication message sent by the local end may be stopped.

After receiving the second matching success indication message sent by the base station controller, the base station may determine the initial time slot pattern as the time slot pattern to be configured by itself. Furthermore, in order to improve the accuracy of the configuration, a three-way handshake can be used. Therefore, after the base station and the base station controller complete the exchange of matching success indication messages, they can further perform a handshake again to detect whether the negotiation between the two ends is successful. That is, it can also include:

Step 205: After detecting the second ACK message sent by the base station control device, the base station sends the first negotiation success message to the base station control device.

Wherein, the negotiated success message can be called an Up message, and the Up message is a newly added message in the embodiment of the present invention, indicating that the negotiation between the local end and the opposite end for the time slot pattern is successful, and the ACK message can be sent at the local end And when the opposite end also sends an ACK message, for example, after the above-mentioned base station sends the first ACK message and receives the second ACK message, it sends an Up message to the base station control device.

The format of the Up message may be as shown in FIG. 5 . Referring to FIG. 5 , a newly defined value such as 0x00F4 (shown as 00F4 in FIG. 5 ) is used to indicate that the message is a negotiation success message.

Step 206: After detecting the first Up message sent by the base station, the base station control device sends a second Up message to the base station.

After detecting the first Up message, the base station control device determines that the negotiation between the two parties is successful, and then sends the second Up message.

In addition, because the above-mentioned time slot occupancy indication (inform) message, matching success indication (ACK) message, and negotiation success (Up) message belong to PPP messages, in addition to the fields specified above, the PPP message is also included. Some common fields of the message, for example, the first two fields of the above three messages are the common 7E and FF03 in the PPP message.

Step 207: After receiving the second Up message, the base station configures the time slot pattern obtained according to the second inform message as the time slot pattern used by itself.

That is, after successful negotiation between the base station and the base station controller, the base station determines the determined initial time slot pattern as the time slot pattern used by itself.

Afterwards, the configured time slot pattern used by itself may be used to send PPP link information, and perform PPP link establishment negotiation with the base station control device.

In this embodiment, the base station control device notifies the base station of the configured time slot pattern in the time slot occupancy indication message, so that the base station can directly determine the time slot pattern to be configured by itself according to the time slot occupancy indication message, without polling attempts Establishing a link to determine the time slot pattern can quickly determine the time slot pattern used. Theoretically, it can be completed in seconds, but in the prior art, it takes tens of minutes even to poll typical scenarios; There is no limit, it can be determined through the information interaction between the base station and the base station control equipment, so it can support the arrangement and combination of any time slot, avoiding the problem that the existing technology is not applicable after the typical scene is changed, and can ensure that the scene can still be relocated Be applicable.

The embodiment shown in FIG. 2 is an example of a time slot pattern that is not configured by the base station after startup. For the scenario where the base station is restarted, that is, the base station has previously configured time slots, the process of restarting may be shown in the following embodiments.

Fig. 6 is a schematic flowchart of the third embodiment of the present invention. In this embodiment, the base station is restarted and the original configuration is the same as that of the base station control device as an example. Referring to Figure 6, this embodiment includes:

Step 601: After restarting, the base station sends a first ACK message to the base station control device.

Wherein, the base station may store the original time slot pattern in a cache (FLASH) after power-off, and the time slot pattern stored in the cache may be called an initial time slot pattern. Afterwards, when restarting, the initial time slot pattern can be directly used to send the ACK message.

For example, if the time slot numbers corresponding to the original time slot pattern are 2, 4, and 6, then the base station will send ACK messages on the 2nd, 4th, and 6th time slots of the sent E1 frame after restarting, and carry the time slot numbers respectively. Number 2, 4, 6.

Step 602: After detecting the first ACK message, the base station control device compares the time slot pattern indicated by the first ACK message with the time slot pattern configured by itself, and sends a second ACK message to the base station when the two are the same.

Because the base station is restarted, the configuration in the base station control device may change during the time when the base station is powered off. Therefore, even if the original configuration of the base station is obtained from the base station control device, the configurations of the two may be different after the base station is restarted. of. Of course, if the two are the same, the base station control device may send an ACK message to the base station.

Step 603: After detecting the second ACK message sent by the base station control device, the base station sends a first negotiation success (Up) message to the base station control device.

Step 604: After detecting the first Up message sent by the base station, the base station control device sends a second Up message to the base station.

Step 605: After receiving the second Up message, the base station configures the original initial time slot pattern as the time slot pattern used by itself. Afterwards, the configured time slot pattern used by itself may be used to send PPP link information, and perform PPP link establishment negotiation with the base station control device.

The base station in this embodiment initiates the confirmation process of the time slot pattern after restarting, and determines the original time slot pattern as the current time slot pattern after receiving the ACK message sent by the base station control device, which can avoid using wrong time slots pattern.

FIG. 7 is a schematic flowchart of a fourth embodiment of the present invention. In this embodiment, a base station is restarted and the original configuration is different from that of the base station control device as an example. Referring to Figure 7, this embodiment includes:

Step 701: After restarting, the base station sends a matching success indication (ACK) message to the base station control device.

Wherein, the base station may store the original time slot pattern in a cache (FLASH) after power-off, and the time slot pattern stored in the cache may be called an initial time slot pattern. Afterwards, when restarting, the original time slot pattern can be directly used to send the ACK message.

For example, if the time slot numbers corresponding to the original time slot pattern are 2, 4, and 6, then the base station will send ACK messages on the 2nd, 4th, and 6th time slots of the sent E1 frame after restarting, and carry the time slot numbers respectively. Number 2, 4, 6.

Step 702: After receiving the ACK message, the base station control device compares the time slot pattern indicated by the ACK message with the time slot pattern configured by itself, and if the two are different, sends a matching failure indication (NACK) message to the base station.

Because the base station is restarted, the configuration in the base station control device may change during the time when the base station is powered off. Therefore, even if the original configuration of the base station is obtained from the base station control device, the configurations of the two may be different after the base station is restarted. of.

When the two are different, the base station control device sends a NACK message, and the NACK message is used to indicate that the time slot configuration of the peer end is different from the time slot configuration of the local end. The format of the NACK message can be referred to in FIG. 8 , and a new value can be defined, for example, 0x00F3 (shown as 00F3 in FIG. 8 ) indicates that the message is a NACK message. In addition, similar to the aforementioned inform message, ACK message, and UP message, the NACK message may also contain some common fields of the PPP message, for example, the first two fields are 7E and FF03 commonly used in the PPP message.

Step 703: After receiving the NACK message sent by the base station control device, the base station determines that the time slot pattern has been changed, and re-determines the time slot pattern.

Wherein, the process of re-determining the time slot pattern may be the embodiment shown in FIG. 2 . That is, the specific content of step 703 may be as shown in steps 201-207.

The base station in this embodiment initiates the confirmation process of the time slot pattern after restarting, and reconfigures the used time slot pattern after receiving the NACK message sent by the base station control device, so that the wrong time slot pattern can be found in time to ensure that the used time slot pattern pattern correctness.

Fig. 9 is a schematic flow chart of the fifth embodiment of the present invention. Since the bearer network between the base station control device and the base station may contain a time slot crossover device (Digital Cross Connect, DXX) device, after passing through the DXX device, the time for peer configuration The slot may be different from the one received by itself. At this point, the corresponding relationship needs to be saved for subsequent maintenance. This example includes:

Step 901: the base station acquires the time slot pattern configured by the base station control device.

Wherein, the base station may determine the time slot number included in the inform message sent by the base station control device as the time slot number corresponding to the time slot pattern configured on the base station control device side. For example, the time slot numbers contained in the inform message sent by the base station control device to the base station are 2, 4, and 6 respectively, and the base station can determine that the time slot numbers corresponding to the time slot patterns configured by the base station control device are 2, 4, and 6 respectively. .

Step 902: The base station determines the receiving time slot number, which is the time slot number when the base station receives the time slot occupation indication message sent by the base station control device.

Among them, since there may be DXX equipment in the bearer network between the base station and the base station control equipment, the time slot relationship may change after passing through the DXX equipment. However, after the DXX device, the base station may receive the time slot occupancy indication message on the 1st, 3rd, and 5th time slots of the E1 frame, then at this time, the base station determines the The slot numbers are 1, 3, 5.

Step 903: the base station saves the corresponding relationship between the received time slot number and the time slot number included in the time slot occupation indication message sent by the base station control device.

For example, when the own time slot number is saved as 1, the corresponding time slot number is 2, and when the own time slot number is 3, the corresponding time slot number is 4, etc.

By saving this correspondence, maintainability can be improved. Specifically, the maintenance of the E1 frame in the prior art is based on the E1 as the processing unit, and the link state can be determined by comparing the E1 frame sent by the base station control device with the E1 received by the base station, and in this embodiment, because it can If the message is carried in each time slot, the processing unit can be refined to the time slot of the E1 frame, and maintenance is performed according to the content of each time slot on the base station side and the content on the base station control device side. For example, compare the content sent by the base station control device in the second time slot with the content received by the base station in the first time slot, and determine the time slot (the base station control device side is the second time slot, the base station side is the first time slot) 1 time slot) is connected, or determine the packet loss rate, bit error rate, etc. corresponding to the time slot (the second time slot on the base station control device side, and the first time slot on the base station side).

In addition, it should be noted that when the time slots of the base station control device and the base station are different, the base station needs to return a corresponding message according to the time slot sent by the base station control device. For example, the time slot numbers contained in the second inform message in FIG. 2 are 2, 4, and 6 respectively, and the base station receives the second inform message in the 1st, 3rd, and 5th time slots. Then, when the base station returns the first ACK message, it still returns in the 2nd, 4th, and 6th time slots, and the time slot numbers carried in the first ACK message are 2, 4, and 6 respectively.

In this embodiment, the base station control device notifies the base station of the configured time slot pattern in the time slot occupancy indication message, so that the base station can directly determine the time slot pattern to be configured by itself according to the time slot occupancy indication message, without polling attempts Establishing a link to determine the time slot pattern can quickly determine the time slot pattern used. Theoretically, it can be completed in seconds, but in the prior art, it takes tens of minutes even to poll typical scenarios; There is no limit, all can be determined through the interaction between the base station and the base station control equipment, so it can support the arrangement and combination of any time slot, avoid the problem that the existing technology is not applicable after the typical scene is changed, and can ensure that the relocation scene is still applicable. Further, in this embodiment, maintainability of the TDM link can be improved by saving the time slot conversion relationship.
