Detailed Description
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments of the present invention may be arbitrarily combined with each other without conflict.
The steps illustrated in the flowchart of the figure may be performed in a computer system such as sets of computer-executable instructions and, although a logical order is illustrated in the flowchart, in some cases, the steps illustrated or described may be performed in an order different than that illustrated herein.
The NB-IoT uses the same frequency band as GSM, and the operating principles of the two systems are partially similar, so there is a possibility of carrier sharing, and the operating principles of the two systems are as follows.
Fig. 1 is a schematic diagram of a downlink channel configuration of each carrier in a multi-carrier cell of an NB-IoT system according to an embodiment of the present invention, as shown in fig. 1, an cell includes Anchor (Anchor) carriers (i.e., control carriers) and a plurality of Non-Anchor (Non-Anchor) carriers (i.e., data carriers), each carrier has a frequency spectrum bandwidth of 180 kilohertz (KHz), and a maximum frequency spectrum span of all carriers in the cell does not exceed 20 megahertz (MHz).
Among them, there are only downlink carriers in the multi-carrier cell, which support to simultaneously carry the Narrowband Primary Synchronization Signal (NPSS), Narrowband Secondary Synchronization Signal (NSSS), Narrowband Physical broadcast Channel (NPBCH), Narrowband Physical Downlink Control Channel (NPDCCH), Narrowband Physical downlink shared Channel (NPDSCH, Narrowband Physical downlink shared Channel), and so on, and the carrier is called Anchor carrier.
In the multi-carrier cell, a plurality of downlink carriers which only carry NPDCCH and NPDSCH but do not carry NPSS, NSSS and NPBCH channels are called Non-Anchor carriers. The UE needs to monitor the NPDCCH and NPDSCH information on Non-Anchor carriers.
Fig. 2 is a schematic diagram of channel configuration of GSM according to an embodiment of the present invention. As shown in fig. 2, in GSM, it is assumed that a cell has n carrier frequencies, denoted by C0 and C1 … Cn, and 8 slots per carrier frequency, denoted by Ts0 and Ts1 … Ts7, and the slot width is 15/26 milliseconds (ms).
The Control Channel is fixedly mapped to Ts0 time slot of carrier C0, such as Frequency Correction Channel (FCCH), Synchronization Channel (SCH), Broadcast Control Channel (BCCH) and Common Control Channel (CCCH, Common Control Channel), C1 to Cn are all used for data transmission, Ts0 to Ts7 are all data channels.
In summary, GSM and NB-IoT systems commonly use 200KHz bandwidth, and the control channel is transmitted on a fixed carrier, and the data channel is transmitted on other carriers, so when the anchor carrier of the NB-IoT system and the control carrier of GSM are independent, it is possible to share the carrier frequency of the transmission data channel between the NB-IoT system and GSM.
Referring to fig. 3, embodiments of the present invention propose carrier sharing methods, including:
step 300, when the th communication node judges that own carrier resources are insufficient and receives a th message of a second communication node, the th communication node transmits data on the idle carrier, wherein the th message comprises a th correspondence between a cell identifier of the second communication node and carrier information of the idle carrier, and the th communication node and the second communication node belong to different communication systems.
In this embodiment of the present invention, an absolute value of a difference between a spectrum bandwidth of a carrier of the th communication node and a spectrum bandwidth of a carrier of the second communication node is less than or equal to a preset threshold.
In the embodiment of the present invention, the th communication node may determine whether its own carrier resource is sufficient by at least of the current used power of the carrier and the number of Physical Resource Blocks (PRBs) currently used by the carrier.
For example, when the current used power of the carrier is greater than or equal to th predetermined limit, the carrier resource is considered insufficient, and when the current used power of the carrier is less than th predetermined limit, the carrier resource is considered sufficient.
As another example, when the number of PRBs currently used by a carrier is greater than or equal to th predetermined limit, the carrier resources are considered insufficient, and when the number of PRBs currently used by a carrier is less than th predetermined limit, the carrier resources are considered sufficient.
In another embodiments of the present invention, the mapping further includes a cell ID of the th communication node.
In an embodiment of the invention, the carrier information comprises a frequency point value.
In the embodiment of the present invention, the th communication node may first determine whether its own carrier resource is sufficient and then receive the th message of the second communication node, or the th communication node may first receive the th message of the second communication node and then determine whether its own carrier resource is sufficient.
() the th cn first determines whether its own carrier resources are sufficient, and then receives the th message from the second cn.
In this case, the th communication node needs to determine whether its own resources of all carriers are sufficient, and when the th communication node has insufficient own carrier resources, before the receiving the th message of the second communication node, the method further includes:
the communication node sending a third message to a second communication node, the third message including a cell identity corresponding to the communication node's insufficient resource carrier, or a third correspondence between the cell identity corresponding to the communication node's insufficient resource carrier and the second communication node's cell identity.
Specifically, when the third correspondence between the cell identifier of the th communication node and the cell identifier of the second communication node is only configured in the th communication node, the third message includes the third correspondence between the cell identifier corresponding to the carrier with insufficient resources of the th communication node and the cell identifier of the second communication node;
when the third correspondence relationship is configured only in the second communication node, the third message includes a cell identifier corresponding to a carrier with insufficient resources of the th communication node;
when the third correspondence relationship is configured in both the th communication node and the second communication node, the third message may include a cell identity corresponding to the resource-deficient carrier of the th communication node, or include a third correspondence relationship between a cell identity corresponding to the resource-deficient carrier of the th communication node and a cell identity of the second communication node.
In an embodiment of the present invention, the third message may be a carrier sharing request (frequencysarringrequest).
When the cell identifier comprises the base station identifier and the cell identifier, the communication node sends the third message to the second communication node corresponding to the base station identifier in the cell identifier of the second communication node corresponding to the carrier with insufficient resources of the th communication node when the carrier resources of the communication node are insufficient, and when the cell identifier does not comprise the base station identifier, the corresponding relation between the th communication node identifier and the second communication node identifier needs to be configured between the th communication node and the second communication node, and the second communication nodes to which the third message is sent can be known based on the corresponding relation between the th communication node identifier and the second communication node identifier.
In another embodiments of the present invention, when the communication node does not receive the response message (e.g., the message or the fourth message) from the second communication node within a preset time after sending the third message to the second communication node, the communication node resends the third message to the second communication node.
The th communication node receives the th message of the second communication node and then determines whether its own carrier resources are sufficient.
In this case, the th communication node only needs to determine whether the resource of the carrier corresponding to the th communication node's cell id corresponding to the second communication node's cell id in the th correspondence is sufficient, and when the carrier resource is insufficient, directly transmit data on the idle carrier corresponding to the second communication node's cell id.
Specifically, when the -th correspondence includes the cell id of the -th communication node, the 0-th communication node directly determines whether the resource of the carrier corresponding to the cell id of the -th communication node in the -th correspondence is sufficient, and when the -th correspondence does not include the cell id of the -th communication node, the -th communication node searches the cell id of the -th communication node corresponding to the cell id of the second communication node in the -th correspondence in the preconfigured third correspondence, and then determines whether the resource of the carrier corresponding to the cell id of the -th communication node that is found is sufficient.
In the embodiment of the present invention, it may be determined whether the second communication node has an idle carrier by determining whether the carrier information of the idle carrier in the th message is empty.
In the embodiment of the present invention, when the second communication node does not have a free carrier, the th communication node may wait for the next cycles or receive the th message again, and consider that no free carrier is sharable for the second communication node before receiving the th message again.
In this embodiment of the present invention, the th communication node transmits data on a carrier corresponding to the cell id of the second communication node corresponding to the cell id corresponding to the carrier with insufficient resource of the th communication node, that is, the cell id of the th communication node and the cell id of the second communication node that satisfy the third correspondence relationship cannot perform carrier sharing, and the cell id of the th communication node and the cell id of the second communication node that do not satisfy the third correspondence relationship cannot perform carrier sharing.
In this embodiment of the present invention, when the th communication node does not occupy any idle carriers, the carrier information of the occupied carriers is null.
In an embodiment of the present invention, the th communication node may periodically send a second message to the second communication node.
In another embodiments of the present invention, after the communication node sends the third message to the second communication node, and before the communication node receives the message from the second communication node, the method further comprises:
the th communication node receives the fourth message of the second communication node.
The fourth message may be a response message or a carrier sharing response (Frequency SharingResponse) to notify the that the communication node has received the third message, so that the communication node does not repeatedly send the third message because the message is not received for a long time.
The method avoids message redundancy caused by the th communication node repeatedly sending the third message without receiving the th message for a long time after sending the third message.
In another embodiments of the present invention, the method further comprises:
the communication node receives a fifth message, wherein the fifth message comprises a fourth corresponding relation between the cell identifier of the second communication node and the carrier information of the carrier needing to be recovered, the communication node releases the carrier needing to be recovered and sends a sixth message to the second communication node, and the sixth message comprises a fifth corresponding relation between the cell identifier of the communication node and the carrier information of the released carrier.
In another embodiments of the present invention, after the communication node receives the fifth message and before the communication node releases the carrier needing to be recovered, the method further includes:
the th communications node sends a seventh message to the second communications node.
The seventh message may be a response message for informing the second communication node that the fifth message has been received, so that the second communication node does not repeatedly send the fifth message because the sixth message is not received for a long time. It should be noted that the seventh message is only a response to the fifth message, and does not need to carry any information, and any form of notification message is possible.
The method avoids message redundancy caused by repeatedly sending the fifth message without receiving the sixth message for a long time after the second communication node sends the fifth message.
Referring to fig. 4, another embodiments of the present invention provide a carrier sharing method, including:
step 400, the second communication node evaluates the load condition of the carrier of the second communication node, and sends a message to the communication node according to the load condition of the carrier of the second communication node, wherein the message comprises the corresponding relation between the cell identifier of the second communication node and the carrier information of the idle carrier, and the communication node and the second communication node belong to different communication systems.
In this embodiment of the present invention, an absolute value of a difference between a spectrum bandwidth of a carrier of the th communication node and a spectrum bandwidth of a carrier of the second communication node is less than or equal to a preset threshold.
In another embodiments of the present invention, the mapping further includes a cell id of the th communication node, specifically, when the third mapping is configured only at the th communication node, the th mapping does not include a cell id of the th communication node;
when the third correspondence is configured only at the second communication node, the th correspondence includes a cell identity of the th communication node;
when the third correspondence relationship is configured between the th communication node and the second communication node, the th correspondence relationship may include the cell id of the th communication node, or may not include the cell id of the th communication node.
In an embodiment of the invention, the carrier information comprises a frequency point value.
When there is no idle carrier, the carrier information is null.
In the embodiment of the present invention, the second communication node may evaluate the load condition of its own carrier by at least of the current used power of the carrier and the number of users currently carried by the carrier.
For example, when the current used power of the carrier is less than or equal to a second predetermined limit, the load of the carrier is considered to be less than or equal to a second predetermined limit, i.e., the carrier is in an idle state, and when the current used power of the carrier is greater than a second predetermined limit, the load of the carrier is considered to be greater than a second predetermined limit, i.e., the carrier is in a non-idle state.
For another example, when the number of users currently carried by the carrier is less than or equal to the second predetermined limit, the load of the carrier is considered to be less than or equal to the second predetermined limit, that is, the carrier is in an idle state, and when the number of users currently carried by the carrier is greater than the second predetermined limit, the load of the carrier is considered to be greater than the second predetermined limit, that is, the carrier is in a non-idle state.
In the embodiment of the present invention, the second communication node may evaluate the load condition of the self-carrier after receiving the th communication node's third message, or the second communication node may evaluate the load condition of the self-carrier in the sharing time period.
() the second communication node evaluating the load condition of the self carrier upon receiving the third message of the th communication node.
In this case, the third message comprises the cell identity of the th communication node or a third correspondence between the cell identity of the th communication node and the cell identity of the second communication node.
The second communication node evaluates only the load condition of the carrier corresponding to the cell identity of the second communication node in the third correspondence.
When the third message only includes the cell identifier of the th communication node, the second communication node searches the cell identifier of the second communication node corresponding to the cell identifier of the th communication node in the third message in a pre-configured third correspondence, and then evaluates the carrier load condition corresponding to the searched cell identifier of the second communication node.
In an embodiment of the present invention, the third message may be a carrier sharing request (Frequency SharingRequest).
And (II) the second communication node evaluates the load condition of the self carrier in the sharing time period.
In this case, the second communication node evaluates the load conditions of all the carriers of itself within the shared period.
The second communication node may periodically send messages to the th communication node or may send messages to the th communication node when the own carrier status changes (e.g., from idle to non-idle, or from non-idle to idle).
Step 401, the second communication node receives a second message of the th communication node, where the second message includes a second correspondence between the cell identifier of the th communication node and the carrier information of the occupied carrier.
In another embodiments of the present invention, after the second communication node receives the third message from the th communication node, before the second communication node evaluates the load condition of its own carrier, the method further includes:
the second communications node sending a fourth message to the th communications node indicating receipt of the th message.
The fourth message may be a response message or a carrier sharing response (Frequency SharingResponse) to notify the that the communication node has received the third message, so that the communication node does not repeatedly send the third message because the message is not received for a long time.
The method avoids message redundancy caused by the th communication node repeatedly sending the third message without receiving the th message for a long time after sending the third message.
In another embodiments of the present invention, the method further comprises:
when the second communication node needs to recover the carrier occupied by the communication node, the second communication node sends a fifth message to the communication node, wherein the fifth message comprises a fourth corresponding relation between the cell identifier of the second communication node and the carrier information of the carrier needing to be recovered;
and the second communication node receives a sixth message of the communication node, wherein the sixth message is a fifth corresponding relation between the cell identifier of the communication node and the carrier information of the released carrier, and indicates a user to transmit data on the released carrier.
In the embodiment of the invention, the situation that the carrier which is occupied by the th communication node needs to be recovered comprises the following two situations that the sharing time period is over, or the carrier load of the second communication node is suddenly increased, namely the carrier resource of the second communication node is insufficient.
Specifically, when the sharing time period is over, the second communication node recovers all the shared carriers;
when the carrier resource of the second communication node is insufficient, the second communication node recovers all the shared carriers, or recovers the shared carriers one by one, that is, it determines whether the carrier resource is sufficient again every time carriers are recovered, which is not limited in the embodiment of the present invention.
In another embodiments of the present invention, after sending the fifth message to the communication node and before the second communication node receives the sixth message from the communication node, the method further comprises:
the second communications node receives the seventh message from the communications node.
The seventh message may be a response message for informing the second communication node that the fifth message has been received, so that the second communication node does not repeatedly send the fifth message because the sixth message is not received for a long time. It should be noted that the seventh message is only a response to the fifth message, and does not need to carry any information, and any form of notification message is possible.
The method avoids message redundancy caused by repeatedly sending the fifth message without receiving the sixth message for a long time after the second communication node sends the fifth message.
In the above embodiment, the th communication node and the second communication node may be base stations belonging to different communication systems, for example, the th communication node is an eNodeB of an NB-IoT system, and the second communication node is a BSC of GSM.

The connection mode of NB-IoT and GSM network elements is as shown in fig. 3, an interface is established between the BSC and the MME, message interaction between the BSC and the eNodeB is conducted through the MME, and NB-IoT and GSM are assisted to complete a carrier sharing function.
The specific implementation of the embodiment of the present invention is described in detail below by taking an NB-IoT system sharing a GSM carrier as an example.
NB-IoT system and GSM use sets of carriers with same frequency band, wherein NB-IoT system and GSM have own control carrier respectively, NB-IoT system and GSM only share data carrier, that is, NB-IoT system uses GSM data carrier to send information needed to be sent by Non-Anchor carrier when Non-Anchor carrier resource is not enough.
The control node shared by the NB-IoT system and the GSM carrier is: an Evolved node B (eNodeB) and a Base Station Controller (BSC), which respectively control whether to use a carrier sharing function between the NB-IoT system and the GSM. As shown in fig. 8, an interface is newly established between the GSM BSC and the Mobility Management Entity (MME), and the MME transparently passes through the content that needs to be interacted between the BSC and the eNodeB.
Example 1
In this example, when the user in GSM decreases, the GSM spectrum resource appears to be insufficiently utilized, the BSC evaluates the load condition of its own carrier (e.g., the current power used by the carrier), then gradually migrates the user to a certain or a few carriers, so that the user data is sent on a few carriers in a centralized manner, and the rest carriers are left empty for energy-saving dormancy. With the use of NB-IoT base stations deployed in the same frequency band, as the number of users increases, when spectrum resources are not enough, spectrum resources of GSM can be shared.
Referring to fig. 9, the method includes:
and 900, configuring a third corresponding relation between the cell identifier of the eNodeB and the cell identifier of the BSC in advance at the eNodeB.
In this step, the cell id of the eNodeB meeting the third correspondence may share the carrier corresponding to the cell id of the BSC. For example, if the cell 11 of the eNodeB and the cell 21 of the BSC satisfy the third correspondence relationship, the cell 11 of the eNodeB may share the carrier corresponding to the cell 21 of the BSC; if the cell 12 of the eNodeB and the cell 22 of the BSC do not satisfy the third correspondence, the cell 21 of the eNodeB may not share the carrier corresponding to the cell 22 of the BSC.
Step 901, the eNodeB judges whether the carrier resources of the eNodeB are sufficient, and when the carrier resources of the eNodeB are insufficient, the eNodeB sends a carrier sharing request to the BSC through the MME, where the carrier sharing request includes a third correspondence between a cell identifier corresponding to the carrier with insufficient resources of the eNodeB and a cell identifier of the BSC; when the carrier resources are sufficient, the process is ended.
In this step, the eNodeB determines whether or not its own carrier resources are sufficient by at least of the current power used by the carrier and the number of PRBs currently used by the carrier.
When the current use power of the carrier or the number of PRBs currently used by the carrier is greater than or equal to the preset limit of , which indicates that the NB-IoT system has a shortage of carrier resources and needs to share idle GSM carrier resources, the eNodeB sends a carrier sharing request to the BSC capable of performing carrier sharing (i.e., the BSC corresponding to the BSC's cell identifier in the third correspondence in the carrier sharing request) through the MME.
If the eNodeB does not receive the BSC's response message within timer durations, the carrier sharing request will be reinitiated.
In this step, the MME transparently transmits the carrier sharing request.
Step 902, the BSC sends a response message to the eNodeB indicating that the carrier sharing request is received.
Step 903, the BSC evaluates the load condition of the carrier corresponding to the BSC cell identifier in the third correspondence in the carrier sharing request, and periodically sends th message to the eNodeB through the MME according to the load condition of the carrier, where the th message includes the th correspondence between the BSC cell identifier and the frequency point value of the idle carrier.
In this step, when the BSC has no idle carrier, the frequency point value of the idle carrier is null.
Step 904, when the frequency point value of the idle carrier in the message is not empty, the eNodeB transmits data on the idle carrier and sends a second message to the BSC through the MME, the second message including a second correspondence between the cell identifier of the eNodeB and the frequency point value of the occupied carrier, and when the frequency point value of the idle carrier in the message is empty, the eNodeB waits for cycles to receive the message.
Step 905, when the BSC needs to recover the carrier occupied by the eNodeB, sending a fifth message to the eNodeB through the MME, where the fifth message includes a fourth corresponding relationship between the cell identifier of the BSC and the frequency point value of the carrier that needs to be recovered.
Step 906, the eNodeB sends a response message to the BSC through the MME, indicating that the fifth message is received.
Step 907, the eNodeB releases the carrier to be recovered in the fifth message, and after the release is completed, the eNodeB sends a sixth message to the BSC through the MME, where the sixth message includes a fifth correspondence between the cell identifier of the eNodeB and the frequency point value of the released carrier.
Step 908, the BSC transmits data on the released carriers in the sixth message.
Example 2
In this example, when the user in GSM decreases, the GSM spectrum resource appears to be insufficiently utilized, the BSC evaluates the load condition of its own carrier (e.g., the current power used by the carrier), then gradually migrates the user to a certain or a few carriers, so that the user data is sent on a few carriers in a centralized manner, and the rest carriers are left empty for energy-saving dormancy. With the use of NB-IoT base stations deployed in the same frequency band, as the number of users increases, when spectrum resources are not enough, spectrum resources of GSM can be shared.
Referring to fig. 10, the method includes:
and step 1000, configuring a third corresponding relation between the cell identifier of the eNodeB and the cell identifier of the BSC in advance in the BSC.
In this step, the cell id of the eNodeB meeting the third correspondence may share the carrier corresponding to the cell id of the BSC. For example, if the cell 11 of the eNodeB and the cell 21 of the BSC satisfy the third correspondence relationship, the cell 11 of the eNodeB may share the carrier corresponding to the cell 21 of the BSC; if the cell 12 of the eNodeB and the cell 22 of the BSC do not satisfy the third correspondence, the cell 21 of the eNodeB may not share the carrier corresponding to the cell 22 of the BSC.
1001, the eNodeB judges whether the carrier resources of the eNodeB are sufficient, and when the carrier resources of the eNodeB are insufficient, the eNodeB sends a carrier sharing request to the BSC through the MME, where the carrier sharing request includes a cell identifier corresponding to the carrier with insufficient resources of the eNodeB; when the carrier resources are sufficient, the process is ended.
In this step, the eNodeB determines whether or not its own carrier resources are sufficient by at least of the current power used by the carrier and the number of PRBs currently used by the carrier.
When the current use power of the carrier or the number of PRBs currently used by the carrier is greater than or equal to the preset limit of , which indicates that the NB-IoT system has a shortage of carrier resources and needs to share idle GSM carrier resources, the eNodeB sends a carrier sharing request to the BSC capable of performing carrier sharing (i.e., the BSC corresponding to the BSC's cell identifier in the third correspondence in the carrier sharing request) through the MME.
If the eNodeB does not receive the BSC's response message within timer durations, the carrier sharing request will be reinitiated.
In this step, the MME transparently transmits the carrier sharing request.
Step 1002, the BSC sends a response message to the eNodeB indicating that the carrier sharing request is received.
Step 1003, the BSC searches a cell identifier of the BSC corresponding to a cell identifier corresponding to a carrier with insufficient resources of the eNodeB in the carrier sharing request in a preset third corresponding relationship, evaluates the load condition of the searched carrier corresponding to the cell identifier of the BSC, and periodically sends th message to the eNodeB through the MME according to the load condition of the carrier, wherein the th message includes a th corresponding relationship among the cell identifier of the eNodeB, the cell identifier of the BSC, and the frequency point value of the idle carrier.
In this step, when the BSC has no idle carrier, the frequency point value of the idle carrier is null.
And 1004, when the frequency point value of the idle carrier in the th message is not empty, the eNodeB transmits data on the idle carrier and sends a second message to the BSC through the MME, wherein the second message comprises a second corresponding relation between the cell identifier of the eNodeB and the frequency point value of the occupied carrier, and when the frequency point value of the idle carrier in the th message is empty, the eNodeB waits for periods to receive the th message.
Step 1005, when the BSC needs to recover the carrier occupied by the eNodeB, sending a fifth message to the eNodeB through the MME, where the fifth message includes a fourth corresponding relationship between the cell identifier of the BSC and the frequency point value of the carrier that needs to be recovered.
Step 1006, the eNodeB sends a response message to the BSC through the MME, indicating that the fifth message is received.
Step 1007, the eNodeB releases the carrier that needs to be recovered in the fifth message, and after the release is completed, the eNodeB sends a sixth message to the BSC through the MME, where the sixth message includes a fifth correspondence between the cell identifier of the eNodeB and the frequency point value of the released carrier.
Step 1008, the BSC transmits data on the released carriers in the sixth message.
Example 3
In this example, GSM implements carrier sharing during a sharing time period.
Referring to fig. 11, the method includes:
1100, configuring a sharing time period (for example, 22: 00-06: 00) which can be shared with NB-IoT at BSC of GSM in advance; and simultaneously configuring a third corresponding relation between the cell identifier of the eNodeB and the cell identifier of the BSC at the BSC.
Step 1101, when the GSM starts the configured sharing time period (for example: 22:00), the GSM evaluates the load condition of the own carrier and releases the GSM carrier that can be shared. If no GSM carrier can be released, no processing is done.
In this step, the BSC may evaluate the load condition of its own carrier by at least of the current used power of the carrier and the number of users currently carried by the carrier.
For example, when the current used power of the carrier is less than or equal to a second predetermined limit, the load of the carrier is considered to be less than or equal to a second predetermined limit, i.e., the carrier is in an idle state, and when the current used power of the carrier is greater than a second predetermined limit, the load of the carrier is considered to be greater than a second predetermined limit, i.e., the carrier is in a non-idle state.
For another example, when the number of users currently carried by the carrier is less than or equal to the second predetermined limit, the load of the carrier is considered to be less than or equal to the second predetermined limit, that is, the carrier is in an idle state, and when the number of users currently carried by the carrier is greater than the second predetermined limit, the load of the carrier is considered to be greater than the second predetermined limit, that is, the carrier is in a non-idle state.
In this step, if the GSM has an energy saving function, that is, when the GSM service data is small, the BSC needs to migrate the user data to a certain carrier or carriers according to the load status of each carrier of the GSM, and perform dormancy on other idle carriers. When the GSM traffic comes, the BSC may migrate the user data to the dormant carrier again, making full use of the spectrum resources. If the GSM does not have the energy-saving function, the BSC directly detects the idle carrier.
If NB-IoT receives a certain frequency point occupied at a certain time, but receives no unoccupied event notification at a later time at , NB-IoT will consider that frequency point is occupied, i.e. if frequency points are occupied, GSM need not repeat the notification.
Step 1102, the BSC periodically sends th messages to the eNodeB through the MME, where the th message includes th correspondence between the cell identifier of the eNodeB, the cell identifier of the BSC, and the frequency point value of the idle carrier.
In this step, the BSC sends th message only to the eNodeB corresponding to the eNodeB whose cell id has the third correspondence with the cell id of the BSC corresponding to the idle carrier.
Step 1103, the eNodeB determines whether the carrier resources corresponding to the cell id of the eNodeB in the message are sufficient, transmits data on the idle carrier in the message when the carrier resources corresponding to the cell id of the eNodeB in the message are insufficient, and periodically sends a second message to the BSC through the MME, where the second message includes a second correspondence between the cell id of the eNodeB and the frequency point value of the occupied carrier, and when the carrier resources corresponding to the cell id of the eNodeB in the message are sufficient, the frequency point value of the occupied carrier in the second message sent to the BSC is empty.
And 1104, when the eNodeB does not need to use the carrier of the BSC, releasing the carrier that does not need to be used, and sending a sixth message to the BSC through the MME, where the sixth message includes a fifth correspondence between the cell identifier of the eNodeB and the frequency point value of the released carrier.
Step 1105, when the sharing time period is over (for example, 06:00), the BSC sends a fifth message to the eNodeB through the MME, where the fifth message includes a fourth correspondence between the cell identifier of the BSC and the frequency point value of the carrier that needs to be recovered, and indicates the carrier that needs to be recovered.
Step 1106, the eNodeB releases the carrier that needs to be recovered, and sends a sixth message to the BSC through the MME, where the sixth message includes a fifth correspondence between the cell identifier of the eNodeB and the frequency point value of the released carrier.
Step 1107, the BSC transmits data on the released carriers in the sixth message.
Example 4
In this example, GSM implements carrier sharing during a sharing time period.
Referring to fig. 12, the method includes:
step 1200, configuring a sharing time period (for example, 22: 00-06: 00) which can be shared with NB-IoT at BSC of GSM in advance; and simultaneously configuring a third corresponding relation between the cell identifier of the eNodeB and the cell identifier of the BSC in the eNodeB.
Step 1201, when the GSM starts the configured sharing time period (for example, 22:00), the GSM evaluates the load condition of the own carrier and releases the GSM carrier that can be shared. If no GSM carrier can be released, no processing is done.
In this step, the BSC may evaluate the load condition of its own carrier by at least of the current used power of the carrier and the number of users currently carried by the carrier.
For example, when the current used power of the carrier is less than or equal to a second predetermined limit, the load of the carrier is considered to be less than or equal to a second predetermined limit, i.e., the carrier is in an idle state, and when the current used power of the carrier is greater than a second predetermined limit, the load of the carrier is considered to be greater than a second predetermined limit, i.e., the carrier is in a non-idle state.
For another example, when the number of users currently carried by the carrier is less than or equal to the second predetermined limit, the load of the carrier is considered to be less than or equal to the second predetermined limit, that is, the carrier is in an idle state, and when the number of users currently carried by the carrier is greater than the second predetermined limit, the load of the carrier is considered to be greater than the second predetermined limit, that is, the carrier is in a non-idle state.
In this step, if the GSM has an energy saving function, that is, when the GSM service data is small, the BSC needs to migrate the user data to a certain carrier or carriers according to the load status of each carrier of the GSM, and perform dormancy on other idle carriers. When the GSM traffic comes, the BSC may migrate the user data to the dormant carrier again, making full use of the spectrum resources. If the GSM does not have the energy-saving function, the BSC directly detects the idle carrier.
If NB-IoT receives a certain frequency point occupied at a certain time, but receives no unoccupied event notification at a later time at , NB-IoT will consider that frequency point is occupied, i.e. if frequency points are occupied, GSM need not repeat the notification.
Step 1202, the BSC periodically sends th messages to the eNodeB through the MME, where the th message includes th correspondence between the BSC's cell identity and the frequency point values of idle carriers.
In this step, the BSC sends th message only to the eNodeB corresponding to the eNodeB whose cell id has the third correspondence with the cell id of the BSC corresponding to the idle carrier.
Step 1203, the eNodeB searches the third correspondence for the cell identifier of the eNodeB corresponding to the cell identifier of the BSC in the -th message, determines whether the carrier resource corresponding to the cell identifier of the eNodeB found is sufficient, transmits data on the idle carrier in the -th message when the carrier resource corresponding to the cell identifier of the eNodeB found is insufficient, and periodically sends a second message to the BSC through the MME, where the second message includes a second correspondence between the cell identifier of the eNodeB and the frequency point value of the occupied carrier, and when the carrier resource corresponding to the cell identifier of the eNodeB found is sufficient, the frequency point value of the occupied carrier in the second message sent to the BSC is empty.
Step 1204, when the eNodeB does not need to use the carrier of the BSC, releasing the carrier that does not need to be used, and sending a sixth message to the BSC through the MME, where the sixth message includes a fifth correspondence between the cell identifier of the eNodeB and the frequency point value of the released carrier.
Step 1205, when the sharing time period is over (for example, 06:00), the BSC sends a fifth message to the eNodeB through the MME, where the fifth message includes a fourth correspondence between the cell identifier of the BSC and the frequency point value of the carrier that needs to be recovered, and indicates the carrier that needs to be recovered.
Step 1206, the eNodeB releases the carrier to be recovered, and sends a sixth message to the BSC through the MME, where the sixth message includes a fifth correspondence between the cell identifier of the eNodeB and the frequency point value of the released carrier.
Step 1207, the BSC transmits data on the released carriers in the sixth message.
