Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a cell switching control method, an apparatus, a cell switching system, and a storage medium.
Background
With The development and improvement of 4G (The 4th Generation mobile communication technology) LTE (long Term evolution) network, a large number of users are moving to The LTE network, and The network frequency resources are also strained. If the 4G network shares the 2G/3G network frequency band, the wide coverage characteristic of the low frequency band can be utilized to provide higher data transmission rate for users, and the investment cost of 4G on sites and frequency spectrum is greatly reduced. In order to adapt to different bandwidth frequency spectrums and improve the utilization rate of scattered frequency spectrums and simultaneously increase the flexibility of frequency spectrum allocation, the multi-system shared frequency band supports 6 standard bandwidth working modes, which are respectively as follows: 1.4M, 3M, 5M, 10M, 15M, 20M, and in practical application, a suitable bandwidth operation mode can be selected according to the existing frequency band resources. In the LTE7.6M scenario of non-standard scheme, LTE uses 10M bandwidth mode, but the actual effective bandwidth is only 7.6M, and the other 2.4M bandwidth will be compressed.
At present, after the area with the condition adopts LTE7.6M nonstandard bandwidth deep replating, the area adjacent to the area may not have 7.6M bandwidth, such as LTE5M bandwidth replating cell. The 7.6M cell and the 5M cell adopt the same central frequency point, so the switching between the two types of cells is the same-frequency switching. When a user is switched from a 5M cell to a 7.6M cell, the terminal considers that the cell is switched to the same frequency switching, and therefore the target cell still has the same bandwidth as the source cell, the terminal still adopts a 5M bandwidth receiving mode, and when scheduling information given to the user by a target base station is beyond the 5M bandwidth, a call drop phenomenon can occur.

Detailed Description
The present disclosure now will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the disclosure are shown. The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
The terms "first", "second", and the like are used hereinafter only for descriptive distinction and not for other specific meanings.
Fig. 1 is a flowchart illustrating a method according to an embodiment of a cell handover control method of the present disclosure, as shown in fig. 1:
The source bandwidth replating cell includes a first LTE system bandwidth replating cell, etc., for example, an LTE5M bandwidth replating cell. The target bandwidth replating cell includes a second LTE system bandwidth replating cell and the like, for example, an LTE7.6M nonstandard bandwidth replating cell. The second bandwidth replating cell and the second bandwidth replating cell may not belong to the same base station. The theoretical bandwidth allocated for use by the second bandwidth replating cell includes an actual effective bandwidth and a compressed bandwidth.
And 102, if the bandwidths of the source bandwidth replating cell and the target bandwidth replating cell are different, sending a system bandwidth change information instruction to the terminal to indicate to the terminal that the used bandwidth after the target bandwidth replating cell is switched is changed. The information carried in the system bandwidth change information command includes bandwidth information of the target bandwidth replating cell and the like.
In order to adapt to different bandwidth frequency spectrums and improve the utilization rate of scattered frequency spectrums and simultaneously increase the flexibility of frequency spectrum allocation, the LTE supports 6 standard bandwidth working modes, which are respectively: 1.4M, 3M, 5M, 10M, 15M, 20M, and in practical application, a suitable bandwidth operation mode can be selected according to the existing frequency band resources. The China telecom C network works in the 800M frequency band, the reverse direction 825M-835M and the forward direction 870M-880M, and comprises 7 frequency points of 37, 78, 119, 160, 201, 242 and 283 and a newly added frequency point 1019. The frequency points are used for representing nominal frequency point numbers of the network working frequency band and can mark the central frequency of the modulated carrier.
In order to make reasonable use of spectrum resources, the bandwidth of 7.6M can be allocated to LTE for use, wherein the number of frequency points is 6 for 37, 78, 119, 160, 201, and 242 of CDMA. If LTE uses 5M bandwidth mode, 2.6M bandwidth will be wasted, which is not reasonable when spectrum resources are scarce. An LTE7.6M nonstandard scheme exists at present, an LTE network adopts a 10M bandwidth mode, works under 7.6M effective bandwidth, and in order to meet terminal compatibility and ensure normal work of the existing terminal, innovative technology is required to support so as to solve the problem which possibly occurs in a multi-system shared frequency range scene.
As shown in fig. 3, LTE7.6M indicates that six frequency bins 37, 78, 119, 160, 201, 242 are occupied by LTE. The theoretical bandwidth allocated to the LTE system is 10M bandwidth, the actual effective bandwidth is 7.6M bandwidth, and the compressed bandwidth is 2.6M bandwidth. LTE7.6M under the non-standard scenario, although LTE adopts 10M bandwidth mode, the actual effective bandwidth is only 7.6M, and the other 2.4M bandwidth will be compressed.
After the terminal is switched from the LTE5M bandwidth replating cell to the LTE7.6M nonstandard bandwidth replating cell, the terminal judges that the target cell still has the same bandwidth as the source cell according to the same-frequency cell switching, so the terminal still adopts a 5M bandwidth receiving mode. When the LTE5M bandwidth replating cell is switched to the LTE7.6M non-standard bandwidth replating cell, the call drop of the terminal is caused because the information of the terminal is not updated in time. When the bandwidths of the same-frequency switching cells are different, after the switching is completed, a signaling is added to indicate that the bandwidth of the terminal system is changed.
In one embodiment, the inter-cell handover occurs when a source cell where the terminal is located and a target cell to be handed over do not belong to the same eNodeB (Evolved Node B). And if the central frequency points of the source bandwidth replating cell and the target bandwidth replating cell are consistent, controlling the terminal to switch the same-frequency cells so that the terminal is switched from the source bandwidth replating cell to the target bandwidth replating cell. After the same-frequency cell is switched, the target cell can directly inform the terminal through signaling, and the system bandwidth is changed.
And controlling the target base station where the target bandwidth replating cell is located to send a system bandwidth change information instruction to the terminal. And after the terminal is determined to be switched to the target bandwidth replating cell, controlling the target base station where the target bandwidth replating cell is located to send a system bandwidth changing information instruction to the terminal, wherein the source bandwidth replating cell does not belong to the target base station.
For example, after the terminal transmits the RRC Reconfiguration Complete to the target base station where the target bandwidth replating cell is located and the target base station replies the HARQ Ack to the terminal, the target base station where the target bandwidth replating cell is controlled to transmit the system bandwidth change information instruction to the terminal.
In one embodiment, the central frequency points of the bandwidths of the LTE5M bandwidth replating cell and the LTE7.6M nonstandard bandwidth replating cell are consistent, the power consumption of the mobile phone can be reduced, the performance is improved, the switching success rate and the time delay index are improved in a same-frequency switching mode, but the information updating of the terminal is not timely caused by the change of the bandwidths, and related signaling and indication information are added in the switching process, so that the call drop phenomenon can be avoided. Fig. 2 is a schematic processing flow diagram of a cell handover control method according to an embodiment of the disclosure, where fig. 2 shows:
Step 204, the eNodeB where the source cell is located configures the allocated dedicated access signature to the terminal, sends an RRC Reconfiguration message to the terminal to instruct the terminal to perform a handover action, and the terminal returns an HARQ Ack after correctly receiving the information.
In step 206, the terminal sends an RRC Reconfiguration Complete message to indicate that the terminal has accessed the new cell, which indicates that the terminal has switched to the target cell, and the eNodeB where the target cell is located correctly receives the information and then returns the HARQ Ack.
Step 207, when the same frequency switching cells have different bandwidths, adding a signaling after the same frequency switching cells are switched, and the target cell directly informs the terminal through the signaling to indicate that the system bandwidth of the terminal is changed. The eNodeB where the target cell is located sends a 'system bandwidth change information indication' informing the terminal that the system bandwidth has changed.
The terminal has accessed a new cell, and can perform service communication in the new cell, and it is necessary to release the resource cell occupied in the source cell.
In one embodiment, as shown in fig. 4, the present invention provides a cell switching control apparatus 40, including: a bandwidth determination module 41, a bandwidth indication module 42 and a cell switching module 43. When it is determined that the terminal is switched from the source bandwidth replating cell to the target bandwidth replating cell, the bandwidth determining module 41 determines whether the bandwidths of the source bandwidth replating cell and the target bandwidth replating cell are the same.
If the bandwidths of the source bandwidth replating cell and the target bandwidth replating cell are different, the bandwidth indicating module 42 sends a system bandwidth change information instruction to the terminal to indicate to the terminal that the used bandwidth after the target bandwidth replating cell is switched is changed, and the information carried in the system bandwidth change information instruction comprises the bandwidth information of the target bandwidth replating cell and the like.
The source bandwidth replanting cell comprises a first LTE system bandwidth replanting cell and the like; the target bandwidth replanting cell comprises a second LTE system bandwidth replanting cell and the like; the second bandwidth replanting cell and the second bandwidth replanting cell do not belong to the same base station; the theoretical bandwidth allocated for use by the second bandwidth replating cell includes an actual effective bandwidth and a compressed bandwidth.
If the central frequency points of the source bandwidth replating cell and the target bandwidth replating cell are determined to be consistent, the cell switching module 43 controls the terminal to switch the same-frequency cells so that the terminal is switched from the source bandwidth replating cell to the target bandwidth replating cell.
The bandwidth indicating module 42 controls the target base station where the target bandwidth replating cell is located to send a system bandwidth change information instruction to the terminal. After determining that the terminal is switched to the target bandwidth replanting cell, the bandwidth indicating module 42 controls the target base station where the target bandwidth replanting cell is located to send a system bandwidth change information instruction to the terminal, wherein the source bandwidth replanting cell does not belong to the target base station.
The bandwidth indicating module 42 controls the target base station where the target bandwidth replating cell is located to send a system bandwidth change information instruction to the terminal after the terminal sends the RRC Reconfiguration Complete to the target base station where the target bandwidth replating cell is located and the target base station replies the HARQ Ack to the terminal.
