Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
In the prior art, when the base station reconfigures the terminal, it usually meets a certain condition or has a certain requirement, for example, when accessing, it needs to configure corresponding resources for the terminal through the reconfiguration message, when the signal is good, it configures carrier aggregation through the reconfiguration message, and when the reconfiguration message has content that is not supported by the terminal, the terminal will send a re-establishment request message, such as the content in the following 36.331 protocol, and at this time, the cause of the re-establishment is reconfiguration failure.
When the terminal re-accesses, the condition of sending the previous reconfiguration message is still usually satisfied, so the reconfiguration message is still sent, but the terminal still does not support, and the re-establishment occurs again, and the process is repeated.
The idea of the embodiment of the invention is as follows: when the terminal initiates the reestablishment request, and the obtained reason that the terminal initiates the reestablishment request is reconfiguration failure, the base station cancels the sending of the reconfiguration message to the terminal according to the times that the terminal sends the reestablishment request to the first cell, so that the repeated reestablishment of the terminal can be avoided, the times of reestablishment of the terminal are reduced, and the signaling overhead and the resource waste of the base station side are reduced.
Example one
Referring to fig. 1, a flowchart of steps of a connection reestablishment method according to an embodiment of the present invention is shown, where the connection reestablishment method may be applied to a base station, and specifically includes the following steps:
step 101: when a reestablishment request corresponding to a first cell reported by a terminal is received, acquiring a request reason for the terminal to send the reestablishment request; wherein the first cell is a cell to which the base station belongs.
In the embodiments of the present invention, the base station means that the public mobile communication base station is a form of a radio station, and means a radio transceiver station for information transfer with a mobile phone terminal through a mobile communication switching center in a certain radio coverage area.
The base station may be a macro base station, a micro base station, a pico base station, a distributed base station, a remote radio unit rru (radio remote unit), and the like, and specifically, may be determined according to an actual situation.
The first cell may be one of cells under the base station, and is a cell corresponding to the terminal when reporting the re-establishment request.
The request reason refers to a reason why the terminal reports a reestablishment request (rrcconnectionrequestablistensionrequest).
When the base station receives the rrcconnectionresedetablsrequest reported by the terminal and corresponding to the first cell, the rrcconnectionresedetablsrequest reported by the terminal may be analyzed to determine the request reason for reporting.
After acquiring the request reason for sending the reestablishment request by the terminal when the reestablishment request corresponding to the first cell reported by the terminal is received, step 102 is executed.
Step 102: and recording the request times of the terminal sending a reestablishment request corresponding to the first cell to the base station under the condition that the request reason is reconfiguration failure.
The reporting of the rrcconnectionresedetablterrequest by the terminal may be a cause of reconfiguration failure (reconfiguration failure), that is, a reconfiguration message of the base station is received at the terminal, and a reconfiguration process triggered by the reconfiguration failure is executed.
The number of requests is the number of times that the terminal initiates the rrcconnectionrequestrequest in the reconfiguration failure.
And under the condition that the request reason for reporting the RRCConnectionRequiraligmentRequest by the terminal is Reconfiguration failure, the number of times of the request for sending the reestablishment request to the first cell by the terminal can be recorded.
In the present invention, when the request is a reconfiguration failure, a corresponding reconfiguration counter may be started, and counting is performed by the reconfiguration counter, that is, when the request of the rrcconnectionrequestrabepressorsupportionrequest is a reconfiguration failure, a reconfiguration counter +1 is reconstructed, and so on, the number of times that the request of the rrcconnectionrequestablessorsupportionrequest corresponding to the first cell reported by the terminal is a reconfiguration failure is continuously counted by the reconfiguration counter, that is, the number of times that the terminal initiates the rrcconnectionrequestrequest is the reconfiguration failure under the reconfiguration failure.
Of course, in a specific implementation, other manners may also be used to record the number of times that the terminal sends the rrcconnectionrequestablistensionrequest corresponding to the first cell to the base station under the condition of reconfiguration failure, and specifically, may be determined according to an actual situation, which is not limited in this embodiment of the present invention.
In the case that the request factor is reconfiguration failure, step 103 is performed after recording the number of times that the terminal transmits the request of rrcconnectionrequestablestandrequest corresponding to the first cell to the base station.
Step 103: and when the request times reach the set times, judging whether the terminal has accessed the first cell before the base station sends the reconfiguration message to the terminal.
The set number of times is a threshold of the number of times that the terminal sends the rrcconnectionrequestassignment request to the base station under the condition of reconfiguration failure, which is preset by the base station. The set number may be 3, 5, 6, and the like, and specifically, may be preset by a developer according to an actual situation, and the embodiment of the present invention does not limit a specific value of the set number.
When the request reason is acquired as reconfiguration failure, the number of times of the request of the rrcconnectionrequestabsistensionrequest corresponding to the first cell sent by the terminal to the base station is recorded, and then the number of times of the request may be compared with the set number of times, and when the number of times of the request reaches the set number of times, before the base station sends the reconfiguration message to the terminal, whether the terminal has accessed the first cell or not, that is, whether the terminal has resided in the first cell or not, may be determined.
In case the terminal has accessed the first cell, step 104 is performed.
Step 104: and canceling the sending of the reconfiguration message to the terminal under the condition that the terminal has accessed the first cell.
Under the condition that the terminal has accessed the first cell, the base station can cancel sending the reconfiguration message to the terminal, namely, the reconfiguration message is not sent to the terminal any more, so that repeated reestablishment of the terminal is avoided, and signaling instruction overhead and resource waste on the base station side are reduced.
The embodiment of the invention provides a connection reestablishment method, which comprises the steps of acquiring a request reason for sending a reestablishment request by a terminal when a reestablishment request corresponding to a first cell reported by the terminal is received, wherein the first cell is a cell to which a base station belongs, recording the request times for sending the reestablishment request corresponding to the first cell to the base station by the terminal under the condition that the reconfiguration fails due to the request reason, judging whether the terminal is accessed to the first cell before the base station sends the reconfiguration message to the terminal when the request times reach a set number, and canceling the sending of the reconfiguration message to the terminal under the condition that the terminal is accessed to the first cell. According to the embodiment of the invention, when the terminal initiates the reestablishment request and the obtained reason that the terminal initiates the reestablishment request is reconfiguration failure, the base station cancels the sending of the reconfiguration message to the terminal according to the times that the terminal sends the reestablishment request to the first cell, so that the repeated reestablishment of the terminal can be avoided, and the signaling overhead and the resource waste of the base station side are reduced.
Example two
Referring to fig. 2, a flowchart of steps of a connection reestablishment method according to an embodiment of the present invention is shown, where the connection reestablishment method may be applied to a base station, and specifically includes the following steps:
step 201: when a reestablishment request corresponding to a first cell reported by a terminal is received, acquiring a request reason for the terminal to send the reestablishment request; wherein the first cell is a cell to which the base station belongs.
In the embodiment of the invention, the radio transceiver station performs information transmission with the mobile telephone terminal through the mobile communication switching center.
The base station may be a macro base station, a micro base station, a pico base station, a distributed base station, a remote radio unit rru (radio remote unit), and the like, and specifically, may be determined according to an actual situation.
The first cell may be one of cells under the base station, and is a cell corresponding to the terminal when reporting the re-establishment request.
The request reason refers to a reason why the terminal reports a reestablishment request (rrcconnectionrequestablistensionrequest).
When the base station receives the rrcconnectionresedetablsrequest reported by the terminal and corresponding to the first cell, the rrcconnectionresedetablsrequest reported by the terminal may be analyzed to determine the request reason for reporting.
After acquiring the request reason for sending the reestablishment request by the terminal when the reestablishment request corresponding to the first cell reported by the terminal is received, step 202 is executed.
Step 202: and recording the request times of the reestablishment request corresponding to the first cell from the base station side by the terminal under the condition that the request reason is reconfiguration failure.
The reporting of the rrcconnectionresedetablterrequest by the terminal may be a cause of reconfiguration failure (reconfiguration failure), that is, a reconfiguration message of the base station is received at the terminal, and a reconfiguration process triggered by the reconfiguration failure is executed.
The number of requests is the number of times that the terminal initiates the rrcconnectionrequestrequest in the reconfiguration failure.
And under the condition that the request reason for reporting the RRCConnectionRequiraligmentRequest by the terminal is Reconfiguration failure, the number of times of the request for sending the reestablishment request to the first cell by the terminal can be recorded.
In the present invention, when the request is a reconfiguration failure, a corresponding reconfiguration counter may be started, and counting is performed by the reconfiguration counter, that is, when the request of the rrcconnectionrequestrabepressorsupportionrequest is a reconfiguration failure, a reconfiguration counter +1 is reconstructed, and so on, the number of times that the request of the rrcconnectionrequestablessorsupportionrequest corresponding to the first cell reported by the terminal is a reconfiguration failure is continuously counted by the reconfiguration counter, that is, the number of times that the terminal initiates the rrcconnectionrequestrequest is the reconfiguration failure under the reconfiguration failure.
Of course, in a specific implementation, other manners may also be used to record the number of times that the terminal sends the rrcconnectionrequestablistensionrequest corresponding to the first cell to the base station under the condition of reconfiguration failure, and specifically, may be determined according to an actual situation, which is not limited in this embodiment of the present invention.
In the case that the request cause is reconfiguration failure, step 203 is executed or step 204 is executed after recording the number of times that the terminal sends the request of rrcconnectionrequestablestandrequest corresponding to the first cell to the base station.
Step 203: and returning to the step of obtaining the request reason for sending the reestablishment request by the terminal when the reestablishment request corresponding to the first cell reported by the terminal is received when the request times do not reach the set times.
The set number of times is a threshold of the number of times that the terminal sends the rrcconnectionrequestassignment request to the base station under the condition of reconfiguration failure, which is preset by the base station. The set number may be 3, 5, 6, and the like, and specifically, may be preset by a developer according to an actual situation, and the embodiment of the present invention does not limit a specific value of the set number.
When the recorded request times do not reach the set times, the process may return to step 201, re-execute the request reason for the terminal to send the rrcconnectionrequestrequest when receiving the rrcconnectionrequestrequestrequest corresponding to the first cell reported by the terminal, and record the request times for the terminal to send the rrcconnectionrequestrequest corresponding to the first cell to the base station when the request reason is the reconfiguration failure. For example, if the set count is 5 and the recorded request count is 3, it indicates that the request count has not reached the set count.
Step 204: and when the request times reach the set times, judging whether the terminal has accessed the first cell before the base station sends the reconfiguration message to the terminal.
When the request reason is acquired as reconfiguration failure, the number of times of the request of the rrcconnectionrequestabsistensionrequest corresponding to the first cell sent by the terminal to the base station is recorded, and then the number of times of the request may be compared with the set number of times, and when the number of times of the request reaches the set number of times, before the base station sends the reconfiguration message to the terminal, whether the terminal has accessed the first cell or not, that is, whether the terminal has resided in the first cell or not, may be determined.
In case the terminal does not access the first cell, step 205 is performed.
In case the terminal has accessed the first cell, step 209 is performed.
Step 205: and releasing the terminal under the condition that the terminal does not access the first cell before the base station sends the reconfiguration message to the terminal.
Before the base station sends the reconfiguration message to the terminal, the base station may release the terminal without accessing the first cell, and when the terminal sends the rrcconnectionresedetablerequest to the first cell, the base station rejects the terminal to access the first cell.
Step 206 is executed after the step of releasing the terminal in case the terminal does not access the first cell before the base station sends the reconfiguration message to the terminal.
Step 206: recording the number of terminals of the first cell release terminal; and the terminal initiates a reestablishment request for the reconfiguration failure.
The number of terminals refers to the number of terminals that the terminal initiates rrcconnectionrequestablistensionrequest due to reconfiguration failure and is released by the first cell in the case where the first cell is not accessed.
Before the base station sends the reconfiguration message to the terminal, under the condition that the terminal does not access the first cell, the number of terminals of the terminal released by the first cell, that is, the number of terminals refused to access by the first cell, may be recorded, for example, if the first cell refuses to access by three terminals, the number of terminals of the terminal released by the first cell is 3.
It should be understood that the above examples are only examples for better understanding of the technical solutions of the embodiments of the present invention, and are not to be taken as the only limitation of the embodiments of the present invention.
In the embodiment of the present invention, the release user counter may be started, and the terminal may be released when the terminal does not access the first cell before the base station sends the reconfiguration message to the terminal, where the release user counter records that the terminal is released by the first cell, specifically, in this case, when the released terminal increases by one, the release user counter +1 is released, and so on, the final calculation result may be obtained.
Of course, in practical application, the number of terminals released by the first cell may also be counted in other manners, which is not limited in the embodiment of the present invention.
After recording the number of terminals released by the first cell, step 207 is executed.
Step 207: and closing the first cell under the condition that the number of the terminals reaches a preset number.
The preset number refers to a threshold value of the number of terminals released by the first cell, and the preset number may be 30, 40, 50, and the like, and specifically, may be preset by a developer according to an actual situation, which is not limited in this embodiment of the present invention.
And under the condition that the number of the terminals of the terminal released by the first cell reaches the preset number, the base station closes the first cell, namely, the first cell is stopped from being used, the service is not provided by the first cell any more, the first cell can be subsequently maintained by related personnel, and the first cell can be restarted after the maintenance is finished.
After the first cell is turned off, step 208 is performed.
Step 208: and sending a redirection message to the terminal so that the terminal is accessed to a second cell.
The redirection message (redirectorarrinfo) is a message sent by the base station to the terminal to establish a connection with another cell.
The second cell refers to a cell for reestablishing a connection, which is sent by the base station to the terminal, and the second cell may be a cell which is subordinate to the current base station and has a normal state, other than the first cell, or a cell which is subordinate to another base station and has a normal state.
When the second cell is a cell to which the current base station belongs, and the base station acquires the second cell, the base station may acquire a cell with a normal state and a smaller load as the second cell according to states and load conditions of all cells to which the base station belongs, and of course, a plurality of second cells may also be selected for the terminal user to select to camp on.
When the second cell is a cell under the other base station, the base station may monitor the state and the load condition of the cell under the adjacent base station, and select the second cell according to the state and the load condition of the cell under the adjacent base station.
After the first cell is closed, the base station may send a redirection message to the terminal, and the terminal may be accessed to the second cell through the redirection message.
Step 209: and canceling the sending of the reconfiguration message to the terminal under the condition that the terminal has accessed the first cell.
Under the condition that the terminal has accessed the first cell, the base station can cancel sending the reconfiguration message to the terminal, namely, the reconfiguration message is not sent to the terminal any more, so that repeated reestablishment of the terminal is avoided, and signaling instruction overhead and resource waste on the base station side are reduced.
The embodiment of the invention provides a connection reestablishment method, which comprises the steps of acquiring a request reason for sending a reestablishment request by a terminal when a reestablishment request corresponding to a first cell reported by the terminal is received, wherein the first cell is a cell to which a base station belongs, recording the request times for sending the reestablishment request corresponding to the first cell to the base station by the terminal under the condition that the reconfiguration fails due to the request reason, judging whether the terminal is accessed to the first cell before the base station sends the reconfiguration message to the terminal when the request times reach a set number, and canceling the sending of the reconfiguration message to the terminal under the condition that the terminal is accessed to the first cell. According to the embodiment of the invention, when the terminal initiates the reestablishment request and the obtained reason that the terminal initiates the reestablishment request is reconfiguration failure, the base station cancels the sending of the reconfiguration message to the terminal according to the times that the terminal sends the reestablishment request to the first cell, so that the repeated reestablishment of the terminal can be avoided, and the signaling overhead and the resource waste of the base station side are reduced.
