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. 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.
In this application, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
As can be seen from the background art, in the existing communication technology, in a base station networking dense area, a wireless device a is registered on a base station a, and a wireless device B is registered on a base station B, when service communication is established, the wireless device a needs to occupy one channel resource on the base station a, the wireless device B needs to occupy one channel resource on the base station B, and such a cross-area communication service mode must occupy two channel resources. Therefore, the existing cross-region communication causes waste of channel resources and increases the busyness of the base station.
In order to solve the problem, the embodiment of the invention discloses a cross-region communication method, a cross-region communication system, wireless equipment and a base station.
Referring to fig. 1, a cross-region communication scenario is shown. The communication system includes a wireless device 11, a wireless device 12, a wireless device 13, a wireless device 14, a first base station 15, and a second base station 16. The wireless device 11 is in the signal coverage area of the first base station 15. The wireless device 12 and the wireless device 13 are in an overlapping region of signal coverage areas of the first base station 15 and the second base station 16. The wireless device 14 is in the signal coverage area of the second base station 16.
In the communication system shown in fig. 1, a precondition that cross-region communication can be performed is that two wireless devices move from the signal coverage areas of the respective registered base stations to the overlapping area of the signal coverage areas of the two base stations. For example, when the base station registered by the wireless device 12 is the first base station 15 and the base station registered by the wireless device 13 is the second base station 16, and when the wireless device 12 and the wireless device 13 both move to the overlapping area of the signal coverage areas of the first base station 15 and the second base station 16, the wireless device 12 and the wireless device 13 perform cross-area communication because the wireless device 12 and the wireless device 13 are in the overlapping area of the signal coverage areas of the first base station 15 and the second base station 16, the process of the cross-area communication between the wireless device 12 and the wireless device 13 is as follows:
the wireless device 12 sends a service request signaling to the second base station 16 through the first base station 15, the service request signaling containing the first base station channel information that the wireless device 12 is currently registered with.
Or, the wireless device 12 sends a service request signaling to the first base station 15, and when the first base station 15 forwards the service request signaling, the first base station adds the channel information of the first base station currently registered by the wireless device 12 to the service request signaling, and then sends the service request signaling to the second base station 16.
The second base station 16 sends the service request signalling to the wireless device 13.
The wireless device 13 switches the communication channel to the first base station channel based on the first base station channel information in the traffic request signaling.
The wireless device 13 communicates with the wireless device 12 based on the first base station 15 if the channel switching is successful.
If the channel switching of the wireless device 13 fails, if the wireless device 13 adds the channel information of the second base station currently registered by the wireless device to the service request response signaling, the service request response signaling is sent to the first base station 15 through the second base station 16 at this time.
The first base station 15 sends service request reply signaling to the wireless device 12.
The wireless device 12 switches the communication channel to the second base station channel based on the second base station channel information in the service request reply signaling.
The wireless device 12 communicates with the second wireless device 13 based on the second base station 16.
If the first base station 15 adds the first base station channel information currently registered by the wireless device 12 to the service request signaling when forwarding the service request signaling, the first base station 15 sends the service request signaling to the second base station 16 at this time.
The second base station 16 sends the service request signalling to the wireless device 13.
The wireless device 13 switches the communication channel to the first base station channel based on the first base station channel information in the traffic request signaling.
The wireless device 13 communicates with the wireless device 12 based on the first base station 15 if the channel switching is successful.
Since the wireless device 11 and the wireless device 14 are not in the overlapping area of the signal coverage areas of the first base station 15 and the second base station 16, if the wireless device 11 and the wireless device 14 need to communicate, the wireless device 11 occupies one channel resource on the first base station 15, the wireless device 14 occupies one channel resource on the second base station 16, and the wireless device 11 and the wireless device 14 each perform communication based on the occupied channel resources.
In the embodiment of the invention, two wireless devices which need to communicate are switched to the same base station, so that the two wireless devices are registered under the same base station for communication, and only one path of base station channel resource needs to be occupied, thereby avoiding the waste of the channel resource and reducing the busyness of the base station.

In step S208, the second wireless device triggers the second wireless device to perform channel processing when the channel switching fails, that is, adds the currently registered second base station channel information to the service request response signaling. The second wireless device informs the first base station of the service request reply signaling through the second base station.
Step S209: and the first base station sends the service request response signaling to the first wireless equipment.
Step S210: and the first wireless equipment switches the communication channel to the second base station channel based on the second base station channel information in the service request response signaling.

Step S211: the first wireless device communicates with the second wireless device based on the second base station.
In step S211, the first wireless device communicates with the second wireless device under the condition of being in the channel of the second base station.
Optionally, before the second wireless device switches the communication channel to the first base station channel based on the first base station channel information in the service request signaling, the first base station detects whether the load intensity in the first base station channel information of the service request signaling is greater than a preset load intensity, and if the load intensity is less than the preset load intensity, the step of switching the communication channel to the first base station channel based on the first base station channel information in the service request signaling is performed; and if the load intensity is greater than the preset load intensity, determining that the channel switching fails.
The determination of the preset load intensity is set according to the actual situation, and the present invention is not particularly limited.
