Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The relative arrangement of the components and steps, the numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention unless specifically stated otherwise.
Meanwhile, it should be understood that the sizes of the respective portions shown in the drawings are not drawn in an actual proportional relationship for the convenience of description.
Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate.
In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
The applicant found that: the phenomenon of switching failure of the boundary area generally exists in the boundary area of the LTE shared network.
As shown in fig. 1, the frequency (frequency point) of the shared base station is F1; of the two unshared base stations, the frequency of the operator 1 base station is F1, and the frequency of the operator 2 base station is F2, where F2 is different from F1.
At the shared base station (e.g., left side of fig. 1), both users can work normally.
When the user moves to the non-shared area, the operator 1 user switches from the shared base station to the operator 1 base station for the same-frequency switching, and the normal switching can be successful.
The operator 2 user preferentially switches with the same frequency, but the base station of the adjacent cell is a non-shared station, and the access is refused. Then, the operator 2 performs pilot frequency search for handover, but the signal will be subject to strong co-channel interference of a co-channel signal (but access is denied), resulting in a pilot frequency handover failure after signal degradation. This phenomenon is prevalent in the border areas of shared networks.
Fig. 2 is a schematic diagram of an embodiment of a handover method for a border area network of a shared carrier network according to the present invention. Fig. 3 is a schematic diagram of a handover scheme of the border area network of the shared carrier network according to the present invention. As shown in fig. 3, the frequency (frequency point) of the shared base station is F1; of the two unshared base stations, the frequency of the operator 1 base station is F1, and the frequency of the operator 2 base station is F2, where F2 is different from F1.
Preferably, the embodiment of fig. 2 can be performed by the apparatus for switching the border area network of the shared carrier network according to the present invention. As shown in fig. 2, the method comprises the steps of:
step 1, under the condition that a user terminal is in a boundary area of a shared carrier network and moves from a shared cell to a non-shared cell, acquiring the frequencies of the shared cell and the non-shared cell.
And 2, judging whether the frequency of the shared cell is the same as that of the non-shared cell.
And step 3, if the frequency of the shared cell is different from that of the unshared cell, performing network switching by using special pilot frequency Reference Signal Received Quality (RSRQ) as a switching judgment condition as shown in fig. 3. Namely, when the inter-operator and inter-frequency switching is performed in the shared carrier network border area network, the pilot frequency RSRQ is adopted as a switching judgment condition to perform network switching, and a large number of external field actual measurements show that the success rate of switching the border can be remarkably improved by adopting the pilot frequency RSRQ switching.
In one embodiment of the present invention, the method may further include:
and if the frequency of the shared cell is the same as that of the unshared cell, performing network switching by adopting common same-frequency Reference Signal Received Power (RSRP).
Based on the LTE shared carrier network border area network switching method provided by the embodiment of the invention, a special switching strategy is set in the border area of the shared carrier network, the invention adopts novel RSRQ switching during pilot frequency switching for the first time, and experiments prove that the success rate of border switching can be obviously improved. The embodiment of the invention avoids the phenomenon that the call of the user of the pilot frequency switching party is repeatedly dropped due to the existence of obvious same frequency interference signals, and improves the user experience.
Fig. 4 is a schematic diagram of network handover using inter-frequency reference signal received quality RSRQ handover according to an embodiment of the present invention. As shown in fig. 4, the step of performing network handover by using inter-frequency reference signal received quality RSRQ handover in step 3 in the embodiment of fig. 2 may include:
and step 31, acquiring the RSRQ signal of the shared cell and the RSRQ signal of the non-shared cell.
And step 32, determining whether to perform network switching according to the RSRQ signal of the shared cell and the RSRQ signal of the non-shared cell.
Fig. 5 is a diagram illustrating determining whether to perform network handover according to an RSRQ signal of a shared cell and an RSRQ signal of a non-shared cell in an embodiment of the present invention. As shown in fig. 5, step 32 of the embodiment of fig. 4 may include:
step 321, determining whether a difference between the RSRQ signal of the non-shared cell and the RSRQ signal of the shared cell is greater than a predetermined value. If the difference between the RSRQ signal of the non-shared cell and the RSRQ signal of the shared cell is greater than the predetermined value, go to step 322; otherwise, if the difference between the RSRQ signal of the non-shared cell and the RSRQ signal of the shared cell is not greater than the predetermined value, step 323 is executed.
Step 322, triggering inter-frequency handover; after which no further steps of the present embodiment are performed.
In step 323, no inter-frequency handover is performed.
In one embodiment of the present invention, the predetermined value may be 2-3 dB.
The above-described embodiment of the present invention performs a special configuration as shown in fig. 3 in the boundary area:
1. the same-frequency switching is still unchanged by adopting the RSRP scheme.
2. The inter-frequency handover is adjusted to the RSRQ scheme and from the a2+ a4 mode to the A3 mode.
Wherein, a2 indicates that the signal quality of the serving cell is lower than a certain threshold, and when an event meeting the condition is reported, the base station starts the inter-frequency measurement. A4 shows that the quality of the neighboring cell is higher than a certain threshold, and when an event meeting the condition is reported, the source base station starts a handover request. A3 shows that the quality of the neighboring cell is higher than that of the serving cell, and when an event meeting this condition is reported, the source base station starts a handover request.
3. In the boundary area, by comparing the RSRQ signals of the different-frequency neighbor cells, the different-frequency handover is triggered as long as the RSRQ of the different-frequency neighbor cells is better than that of the serving cell by a predetermined value (a typical value of the predetermined value is 2-3 dB).
The applicant shows through a large number of external field actual measurements that the above-mentioned embodiment of the present invention sets a special handover strategy in the boundary region of the shared carrier network, and uses an RSRQ + a3 event to trigger the inter-frequency handover mode, so as to perform inter-frequency handover in advance, thereby significantly improving the success rate of inter-frequency handover in this scenario. The embodiment of the invention avoids the phenomenon that the call of the user of the pilot frequency switching party is repeatedly dropped due to the existence of obvious same frequency interference signals, and improves the user experience.
