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.
It should be understood that the specific embodiments described herein are merely illustrative of the invention, but do not limit the invention to only some, but not all embodiments.
In the NSA networking, in the NSA network environment, a 4G base station is mainly responsible for transmission of control signaling with a terminal, and a 5G base station is mainly responsible for data transmission with the terminal. And after the random access of the 4G base station is successful, the terminal initiates an SgNB addition request to the 5G base station, so that the 5G base station provides data service for the terminal. As shown in fig. 1, fig. 1 is a signaling flow chart of an SgNB addition process provided in the prior art.
The terminal needs to measure the signal quality of the 5G base station and report a measurement report to the 4G base station after the 4G base station succeeds in random access, and if the 4G base station determines that the 5G signal is greater than the threshold value, the 4G base station sends a second base station (SgNB, second generation NodeB) adding request to the 5G base station.
And 102, the 5G base station sends an SgNB addition response to the 4G base station.
The SgNB addition response comprises resource information allocated to the terminal by the 5G base station, a physical cell identifier of a cell of the 5G base station and a measurement frequency point. Namely, the signaling of the SgNB adding flow is finished, and the 5G base station considers that the terminal has been successfully accessed.
After the 5G base station replies an SgNB addition response to the 4G base station, step 103 is executed.
The 4G base station sends an RRC connection reconfiguration message to the terminal so as to send the resources allocated to the terminal by the 5G base station, the physical cell identifier of the cell of the 5G base station and the measurement frequency to the 4G base station, the 4G base station sends an RRC connection reconfiguration message to the terminal so as to send the resources allocated to the terminal by the 5G base station, the physical cell identifier of the cell of the 5G base station and the measurement frequency to the terminal, and the terminal executes step 104 after accepting the resources allocated by the 5G base station.
And step 104, the terminal sends an RRC connection reconfiguration completion message to the 4G base station.
And step 105, the 4G base station sends the completion of the SgNB reconfiguration to the 5G base station.
The terminal now successfully registers on both the 4G and 5G sides.
After the SgNB addition is completed, the terminal initiates a bottom-layer random access procedure to the 5G base station, the terminal sends a Message1 to the 5G base station (Message1), then the 5G base station replies a Message2 to the terminal (Message2), if the terminal does not receive the Message2 sent by the 5G base station or fails to decode the Message2 due to poor channel quality, the terminal reports a failure of the Second Cell Group (SCG) to the 4G base station, which indicates that the random access initiated by the terminal to the 5G base station is not successful, but the 4G base station does not process the situation, and the 5G base station considers that the random access of the terminal is successful and normally allocates resources to the terminal, thereby causing a problem of resource waste allocated by the 5G base station to the terminal.
In order to solve the above technical problem, an embodiment of the present invention provides a method for processing a random access failure. Referring to fig. 2, fig. 2 is a flowchart illustrating steps of a method for processing after a random access failure according to an embodiment of the present invention, where the method is performed in a first base station, and the first base station may be a 4G base station, and the method includes the following steps:
and step 201, receiving a second cell group SCG failure message sent by the terminal.
Referring to the above description of the prior art, when the random access initiated by the terminal to the 5G base station fails, the terminal may send an SCG Failure message (SCG Failure) to the first base station, and correspondingly, the first base station receives the SCG Failure message sent by the terminal.
The first base station can judge whether the random access initiated by the terminal to the second base station fails or not according to the SCG failure message. For example, as shown in step 103 in fig. 1, if the terminal does not successfully reconfigure after receiving the RRC connection reconfiguration message, the terminal may also send an SCG failure message to the first base station. Therefore, in this embodiment, it is determined whether the SCG failure message sent to the first base station is due to a random access failure initiated by the terminal to the second base station according to the received SCG failure message.
And correspondingly, the second base station releases the resources allocated to the terminal according to the SgNB release request message, and the resources allocated to the terminal are, for example, Physical Resource Blocks (PRBs), so that the resources allocated to the terminal can be allocated to other terminals accessing the second base station, and the problem of Resource waste is avoided.
In the processing method after the random access failure provided in this embodiment, the SCG failure message sent by the terminal is received, whether the random access initiated by the terminal to the second base station fails is determined according to the SCG failure message, and under the condition that the random access initiated by the terminal to the second base station fails, the SgNB release request message is sent to the second base station, so that the second base station releases the resource allocated to the terminal according to the SgNB release request message, and thus the released resource can be allocated to other terminals accessing the second base station, and reasonable utilization of the resource is achieved.
Referring to fig. 3, fig. 3 is a signaling flowchart of a processing method after a random access failure according to an embodiment of the present invention, where the method includes the following steps:
The first base station judges whether the random access initiated by the terminal to the second base station fails or not according to the SCG failure message by the following steps:
judging whether the SCG failure message comprises a failure type and a cell identifier of a second base station;
and under the condition that the SCG failure message comprises the failure type and the cell identification of the second base station, determining that the random access initiated by the terminal to the second base station fails.
Correspondingly, the second base station receives the SgNB release request message sent by the first base station, and releases the resources allocated to the terminal according to the SgNB release request message. Step 304 is then performed.
It should be noted that, after sending the SgNB release request message to the second base station, the following steps may be performed:
accumulating the current times of receiving the SCG failure message by 1 to obtain new current times;
judging whether the new current times are greater than or equal to a preset threshold value within preset time;
and under the condition that the new current times are greater than or equal to a preset threshold value within the preset time, if a measurement report sent by the terminal is received, forbidding to initiate an SgNB addition request to the second base station.
Because a terminal can repeatedly measure the signal quality of the 5G base station and report a measurement report to the first base station, if the first base station determines that the 5G signal quality is greater than the threshold value, the first base station sends an SgNB addition request to the second base station, the second base station allocates resources for the terminal, and the terminal frequently initiates random access to the second base station. However, when the terminal cannot use the 5G network, the terminal fails to access the second base station repeatedly, which affects the user experience and causes resource waste of the second base station. Therefore, in this embodiment, a penalty mechanism is added, that is, if the SCG failure message reported by the same terminal within a certain time is greater than or equal to the preset threshold, and the terminal reports the measurement report to the first base station again, the first base station does not send the SgNB addition flow to the second base station, that is, the first base station does not initiate the SgNB addition request to the second base station, so that the resource overhead of the first base station and the second base station is saved.
And step 304, the second base station sends an SgNB release response message to the first base station.
And 305, the first base station sends an RRC connection reconfiguration message to the terminal under the condition that the new current times are greater than or equal to a preset threshold value in preset time.
The RRC connection reconfiguration message is used to instruct the terminal to disconnect an air interface connection with the second base station, so that the terminal disconnects the air interface connection with the second base station, thereby reducing air interface resource consumption.
That is, under the condition that the new current times are greater than or equal to the preset threshold value within the preset time, if the measurement report sent by the terminal is received, the SgNB addition request is prohibited from being initiated to the second base station, so that the 5G base station can be prevented from allocating resources to the terminal.
It should be noted that, in the prior art, as explained in step 103 above: the 4G base station sends RRC connection reconfiguration information to the terminal so as to send the resources distributed by the 5G base station for the terminal, the physical cell identification of the cell of the 5G base station and the measuring frequency to the 4G base station, the 4G base station sends RRC connection reconfiguration information to the terminal, and sends the resources distributed by the 5G base station for the terminal, the physical cell identification of the cell of the 5G base station and the measuring frequency to the terminal, so that the terminal can measure the signal quality of the cell corresponding to the physical cell identification. In this embodiment, when the new current number of times is greater than or equal to the preset threshold within the preset time, the first base station sends an RRC connection reconfiguration message to the terminal, where the RRC connection reconfiguration message does not include the physical cell identifier of the cell of the 5G base station and the measurement frequency point, so that the terminal does not continue to measure the signal quality of the cell corresponding to the physical cell identifier, and resource waste of the terminal is avoided.
And when receiving the RRC connection reconfiguration message, the terminal disconnects the air interface connection with the second base station and does not measure the signal quality of the cell of the 5G base station any more.
The Context Release message is a UE Context Release message, and the second base station releases the Context information of the terminal after receiving the Context Release message sent by the first base station, where the Context information of the terminal includes, for example, user information, terminal information, and bearer information, so that the second base station can save resources required for storing the Context of the terminal, for example, save memory resources and processor resources, and store the saved resources in the Context information of other terminals.
In the processing method after the random access failure provided in this embodiment, by determining whether the new current time is greater than or equal to the preset threshold within the preset time, and under the condition that the new current time is greater than or equal to the preset threshold within the preset time, if a measurement report sent by the terminal is received, the SgNB addition request is prohibited to be initiated to the second base station, that is, the first base station does not initiate any SgNB addition request to the second base station any more, so that resource overhead of the first base station and the second base station is saved.
