Fig. 1 shows a flowchart of a base station reselection method applied to a pico-base station auxiliary device according to an embodiment of the present invention. The base station reselection method applied to the auxiliary equipment of the pico base station can comprise the following steps:
s101: and broadcasting the system message for the terminal equipment which receives the system message to reselect to the auxiliary equipment of the pico base station.
S102: receiving a tracking area updating request sent by the terminal equipment.
The tracking area updating request is sent when the terminal equipment monitors that the tracking area code changes.
S103: and sending a radio resource control connection release message to the terminal equipment, so that the terminal equipment reselects the pico base station corresponding to the pico base station auxiliary equipment.
In one embodiment of the present invention, the system message may include a frequency point of the pico-base station auxiliary device. The rrc connection release message may include a frequency point of the pico-base station corresponding to the pico-base station auxiliary device.
The following describes a method for reselecting a base station according to an embodiment of the present invention with reference to fig. 2. Fig. 2 shows a scene diagram provided by the embodiment of the present invention. The scenario shown in fig. 2 includes a pico-base station auxiliary device, a pico-base station corresponding to the pico-base station auxiliary device, and three terminal devices. The three terminal devices are respectively a terminal device A, a terminal device B and a terminal device C.
The auxiliary equipment of the pico-base station broadcasts a system message, and the system message comprises the frequency point of the auxiliary equipment of the pico-base station.
Assuming that terminal device B is capable of receiving the system message broadcast by the pico-base station assist device, terminal devices a and C are not capable of receiving the system message broadcast by the pico-base station assist device.
And the terminal equipment B sets the frequency point of the auxiliary equipment of the pico-base station as the frequency point occupying the maximum probability. Terminal device B then reselects to the pico-base station auxiliary device.
At this time, the terminal device B monitors that the tracking area code changes, that is, the tracking area code at this time (tracking area code of the pico-base station auxiliary device) is inconsistent with the previous tracking area code, and sends a tracking area update request to the pico-base station auxiliary device.
And after receiving the tracking area updating request sent by the terminal equipment B, the auxiliary equipment of the pico-base station sends a wireless resource control connection release message to the terminal equipment B, wherein the wireless resource control connection release message comprises a frequency point of the pico-base station corresponding to the auxiliary equipment of the pico-base station.
After receiving the rrc connection release message, the terminal device B releases the rrc connection with the pico-base station auxiliary device, and establishes an rrc connection with the pico-base station, i.e., reselects to the pico-base station.
The signaling interaction among the terminal device B, the pico-base station auxiliary device and the pico-base station is shown in fig. 3, and fig. 3 shows a signaling interaction diagram provided by the embodiment of the present invention.
It will be appreciated that the pico base station assist device of the present invention essentially emulates a macro base station, enabling terminal devices to reselect to the pico base station through autonomous behavior.
In an embodiment of the present invention, after reselecting to the pico-base station, the terminal device may reselect to the macro-cell again, and when approaching the pico-base station auxiliary device again and receiving the system message broadcast by the pico-base station auxiliary device, the terminal device may reselect to the pico-base station again, which may cause the terminal device to temporarily disconnect from the network, and affect user experience. It is also possible that the terminal device is far from the pico-base station and cannot connect to the pico-base station, the terminal device may frequently send tracking area update requests to the pico-base station assist device, and the terminal device may also reside in a low generation network (e.g., 2G network).
Based on this, in an embodiment of the present invention, the pico-base station auxiliary device may further detect the number of times of receiving the tracking area update request within a preset time period; and judging whether the number of times of receiving the tracking area updating request reaches a preset number, if so, sending a radio resource control connection release message including a first message to the terminal equipment, wherein the first message is used for indicating that the terminal equipment does not send the tracking area updating request any more.
After receiving the radio resource control connection release message including the first message, the terminal device does not send a tracking area update request to the pico-base station auxiliary device any more.
In an embodiment of the present invention, the first message may be the mobility management related cause value No. 15 (#15), which notifies the terminal device that there is No Suitable cell in the tracking area (No reliable Cells in tracking area). At this time, the terminal device performs cell search in other tracking area codes and selects a large network cell, so that the terminal device is prevented from residing in a low-generation network, and a tracking area update request can be prevented from being frequently sent to the pico-base station auxiliary device.
Fig. 4 is a schematic diagram illustrating a variation of the number of terminal devices camping on a pico base station according to an embodiment of the present invention.
In fig. 4, a pico base station auxiliary device is set at time point X. As can be seen from fig. 4, the number of terminal devices camping on the pico-base station after the time point X is significantly greater than the number of terminal devices camping on the pico-base station before the time point X, and the camping rate of the pico-base station is improved.
