Description

Technical Field

[0001] The present invention relates to the field of wireless communication technologies, and in particular, to a method, apparatus, device, and storage medium for wireless bearer control. Background Art

[0002] The fifth-generation (5G) mobile communication system supports a Standalone (SA) architecture and a Non-Standalone (NSA) architecture. A typical NSA architecture is a Dual Connection (DC) architecture. In the DC architecture, a terminal can operate in a dual-connection mode. In the dual-connection mode, the terminal communicates with two base stations. In practical applications, the primary base station can control the terminal to establish a connection with the secondary base station by triggering a secondary carrier addition process, so as to establish connections with both base stations. During the process of the primary base station triggering the secondary carrier addition process, the primary base station can transfer user plane data to the secondary base station. If a dedicated bearer establishment request such as voice sent by the network side is received, it may indicate that a conflict occurs in the current process, resulting in a problem that the establishment of a dedicated bearer such as voice fails.

[0072] Before introducing the technical solutions of the embodiments of the present invention, the related technologies are described first.

[0073] In the related technologies, in the public network of 5G, there are two network architectures: NSA and SA. Figure 1 It is a schematic diagram of the NAS architecture in the related technologies. As Figure 1 shown, a typical architecture of the NSA network architecture is the 3X architecture, that is, the core network adopts a 4G core network and simultaneously hangs 4G and 5G base stations, and the terminal can be connected to these two base stations at the same time. Among them, the 4G base station is responsible for the control plane, and the data plane splitting point is at the 5G base station; the public network specifically refers to a general commercial network, for example, a commercial network in urban or rural areas.

[0074] Figure 2 Schematic diagram of the conflict between the secondary carrier addition process and the dedicated voice bearer process in the related art, as Figure 2 shown. Taking 4G VoLTE voice as an example, in the NSA networking scenario, the master base station can trigger the secondary carrier (SCG) addition process to control the terminal to establish a connection with the secondary base station, so as to establish connections with both base stations. During the process of the master base station triggering the SCG addition process, the master base station can transfer the user plane data to the secondary base station. If a dedicated voice bearer establishment request sent by the network side is received, since the SCG process conflicts with the dedicated voice bearer establishment process, it will cause the dedicated voice bearer establishment / modification to fail or be released, and transfer the VoLTE voice call to CSFB. Here, the specific reason for the conflict between the SCG process and the dedicated voice bearer establishment process is that after the S1 context is established, when the LTE base station sends B1 measurement or blind configuration to trigger the SCG addition process, the LTE base station sends an E-RAB MODIFICATION INDICATION to the Mobility Management Entity (MME) on the core network side to transfer the user plane data to the 5G base station. The LTE base station does not receive the E-RAB MODIFICATION CONFIRM sent by the MME on the core network side, but receives the QCI1 dedicated bearer establishment / modification process initiated by the MME on the core network side. Since the transfer of the user plane data is not completed yet, the LTE base station replies to the MME on the core network side that the dedicated bearer establishment fails and carries the reason for the process conflict.

[0075] Based on this, in various embodiments of the present invention, a radio bearer establishment request is sent to the network side; the radio bearer establishment request is used to request the network side to establish two radio bearers; based on the two radio bearers, control the execution of the first process and the second process; and / or, receive the first parameter sent by the network side; based on the first parameter, control the execution of the first process and the second process; the first parameter represents the type of radio bearer requested to be established by the network side; wherein, the first process is used for the first base station to control the terminal to establish a connection with the second base station; the first base station is the master base station, and the second base station is the secondary base station; the second process is used for the first base station to establish a dedicated radio bearer.

[0076] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0077] Figure 3 Schematic diagram of the system architecture to which the radio bearer control method according to the embodiment of the present invention is applied; as Figure 1 shown, the system includes a terminal 301, a master base station 302, and a secondary base station 303; wherein,

[0078] The terminal 301 can establish an air interface connection with the master base station 302 (also known as the master node), so as to realize communication with the master base station 302; the terminal 301 can also establish an air interface connection with the secondary base station 303 (also known as the secondary node), so as to realize communication with the secondary base station 303; the terminal 301 can also establish air interface connections with both the master base station 302 and the secondary base station 303 simultaneously, so as to realize communication with both the master base station 302 and the secondary base station 303 simultaneously.

[0079] In the dual-connectivity mode, the terminal 301 establishes two connections with the master base station 302 and the secondary base station 303 simultaneously. Among them, the master base station 302 is mainly responsible for transmitting signaling, and the secondary base station 303 is responsible for transmitting data. The technical solution of the embodiment of the present application is mainly directed to the terminal in the dual-connectivity mode.

[0080] Figure 1 The types of the shown master base station 302 and secondary base station 303 can be the same or different. In one example, the master base station 302 is an LTE base station and the secondary base station 303 is an NR base station. In another example, the master base station 302 is an NR base station and the secondary base station 303 is also an NR base station. In yet another example, the master base station 302 is an NR base station and the secondary base station 303 is an LTE base station. The embodiment of the present application does not limit the types of the master base station 302 and the secondary base station 303.

[0081] In one example, the dual-connectivity mode is the EN-DC mode or the next-generation EN-DC (NGEN-DC) mode. In this case, the master base station is an LTE base station and the secondary base station is an NR base station, and the terminal communicates with both the LTE base station and the NR base station.

[0082] In another example, the dual-connectivity mode is the NR-evolved UMTS (NR-EUTRA, NE-DC) mode. In this case, the master base station is an NR base station and the secondary base station is an LTE base station, and the terminal communicates with both the LTE base station and the NR base station.

[0083] It should be noted that the dual-connection mode is not limited to the above-mentioned EN-DC mode and NE-DC mode, and the embodiments of the present application do not limit the specific type of the dual-connection mode. In specific implementation, the deployment manners of the master base station and the secondary base station can be co-site deployment (for example, an NR base station and an LTE base station can be set on one physical device), or non-co-site deployment (for example, an NR base station and an LTE base station can be set on different physical devices), and the present application may not limit this. Here, the LTE base station can also be referred to as an evolved Node B (eNB), and the NR base station can also be referred to as a next generation Node B (gNB). It should be noted that the present application may not limit the mutual relationship between the coverage ranges of the master base station and the secondary base station. For example, the master base station and the secondary base station can have overlapping coverage. For the specific type of the terminal 301, the present application may not limit this, and it can be any user equipment supporting the above dual-connection mode, such as a smart phone, a personal computer, a laptop computer, and a portable wearable device, etc.

[0084] An embodiment of the present invention provides a radio bearer control method, which is applied to a first base station, such as Figure 4 shown, and the method includes:

[0085] Step 401: Send a radio bearer establishment request to the network side; the radio bearer establishment request is used to request the network side to establish two radio bearers;

[0086] Step 402: Control the execution of a first process and a second process based on the two radio bearers.

[0087] Wherein, the first process is used for the first base station to control the terminal to establish a connection with a second base station; the first base station is the master base station, and the second base station is the secondary base station; the second process is used for the first base station to establish a dedicated radio bearer.

[0088] Here, in step 401, by actively requesting the network side to establish two radio bearers, the first base station can simultaneously meet the requirements for the terminal to establish a dual connection and the requirements for the terminal to initiate a dedicated bearer such as voice. That is to say, during the process of the first base station triggering the secondary carrier addition process, when the first base station transfers user plane data to the secondary base station, if a dedicated bearer establishment request such as voice sent by the network side is received, the first process and the second process can be controlled and executed based on the two radio bearers, without indicating that the current process conflicts with the network side, thereby avoiding the problem of failure in establishing a voice dedicated bearer.

[0089] Here, in step 402, the first process may refer to the secondary carrier addition process, and the second process may refer to the dedicated voice bearer establishment process. During the process of the first base station triggering the secondary carrier addition process, when the first base station transfers user plane data to the secondary base station, if a dedicated bearer establishment request such as voice is received from the network side, the user plane data can be transferred through one of the two radio bearers, and voice can be established through the other radio bearer. In this way, the requirements for the terminal to establish a dual connection and the requirements for the terminal to initiate a dedicated bearer such as voice can be satisfied simultaneously.

[0090] It should be noted that in the embodiments of the present invention, the dedicated bearer includes but is not limited to the dedicated voice bearer.

[0091] The following will describe in detail how to control the execution of the first process and the second process.

[0092] In practical applications, during the process of the first base station triggering the secondary carrier addition process, when the first base station transfers user plane data to the secondary base station, if a dedicated bearer establishment request such as voice is received from the network side, in order to avoid indicating a conflict situation in the current process on the network side, two radio bearers can be actively requested to be established from the network side before the first base station triggers the secondary carrier establishment process.

[0093] Based on this, in an embodiment, the sending of the radio bearer establishment request to the network side includes:

[0094] After the terminal accesses the first base station, a radio bearer establishment request is sent to the network side.

[0095] Here, the terminal accessing the first base station may include:

[0096] The terminal sends a random access request message (Msg1) to the first base station, where the preamble is carried in Msg1; after the first base station receives Msg1, it sends a random access response message (Msg2) to the terminal; after the terminal receives Msg2, it sends a radio resource control (RRC) connection establishment request message (Msg3) to the first base station; after the first base station receives Msg3, it sends an RRC connection establishment message (Msg4) to the terminal; the terminal sends an RRC connection establishment completion message (which can be sent through SIB1) to the first base station.

[0097] For example, Figure 5 is a schematic diagram of the first base station sending a radio bearer establishment request to the network side, as Figure 5As shown, the terminal completes the random access procedure through 4 steps, namely, Step 1: The terminal sends a random access request message (Msg1) to the first base station; Step 2: After receiving Msg1, the first base station sends a random access response message (Msg2) to the terminal; Step 3: After receiving Msg3, the first base station sends an RRC connection establishment message (Msg4) to the terminal; Step 4: The terminal sends an RRC connection establishment completion message to the first base station. After receiving the RRC connection establishment completion message sent by the terminal, the first base station may send a radio bearer establishment request to the network side to request the establishment of two radio bearers.

[0098] In practical applications, after receiving the radio bearer establishment request sent by the first base station, the network side may establish two radio bearers with the same quality of service (QoS); or, after receiving the radio bearer establishment request sent by the first base station, the network side may establish two radio bearers with different QoS levels.

[0099] Based on this, in one embodiment, the sending of the radio bearer establishment request to the network side includes one of the following:

[0100] Sending a radio bearer establishment request to the network side; the radio bearer establishment request is used to request the establishment of two identical radio bearers;

[0101] Sending a radio bearer establishment request to the network side; the radio bearer establishment request is used to request the establishment of two different radio bearers.

[0102] Table 1 shows the corresponding relationship between radio bearers and QCI values. As shown in Table 1, after the terminal accesses the first base station, the first base station may send a radio bearer establishment request to the MME entity on the network side. The radio bearer request is used to request the establishment of two identical radio bearers for the terminal. Among them, the QCI values corresponding to the two radio bearers may be the same. For example, QCI1 = 9, QCI2 = 9. Or, after the terminal accesses the first base station, the first base station sends a radio bearer establishment request to the MME entity on the network side. The radio bearer request is used to request the establishment of two different radio bearers for the terminal. Among them, the QCI values corresponding to the two radio bearers may be different. For example, QCI1 = 9, QCI2 = 6, or QCI1 = 6, QCI2 = 8.

[0103] Whether two radio bearers are the same QCI value Two radio bearers are the same QCI1 = 9, QCI2 = 9 Two radio bearers are different QCI1 = 9, QCI2 = 6 Two radio bearers are different QCI1 = 6, QCI2 = 8

[0104] Table 1

[0105] In practical applications, after receiving the radio bearer establishment request sent by the first base station, the network side may also modify the default radio bearer to a voice dedicated bearer and additionally establish a radio bearer.

[0106] Based on this, in one embodiment, sending the radio bearer establishment request to the network side includes:

[0107] Sending a radio bearer establishment request to the network side; the radio bearer establishment request is used to request to modify the default bearer to a voice bearer and re - establish a radio bearer.

[0108] Here, modifying the default bearer to a voice bearer may include:

[0109] Adjusting the QCI value corresponding to the default bearer from a first value to a second value;

[0110] Wherein, the second value is greater than the first value.

[0111] Table 2 is the correspondence between radio bearers and QCI values. As shown in Table 2, assuming the QCI value of the default radio bearer = 6, if the QCI level required for voice transmission is larger, the QCI value of the default radio bearer can be increased to modify the default bearer to a voice - dedicated bearer. Among them, the adjustment amount of the QCI value can be determined in combination with the current user's demand for voice transmission.

[0112] QCI value of the default radio bearer Modified QCI value QCI1 = 6 QCI1 = 9 QCI1 = 4 QCI1 = 7 QCI1 = 5 QCI1 = 8

[0113] Table 2

[0114] In practical applications, during the process of the first base station triggering the secondary carrier addition process, when the first base station transfers the user - plane data to the secondary base station, if a voice - dedicated bearer establishment request sent by the network side is received, in order to avoid indicating a conflict situation in the current process, the secondary carrier addition process can be continued based on one of the two radio bearers, and the voice - dedicated bearer establishment process can be executed based on the other of the two radio bearers.

[0115] Based on this, in one embodiment, controlling the execution of the first process and the second process based on the two radio bearers includes:

[0116] Executing the first process based on one of the two radio bearers and executing the second process based on the other of the two radio bearers.

[0117] Wherein, the first process may refer to the secondary carrier addition process, and the second process may refer to the voice - dedicated bearer establishment process.

[0118] Here, during the process of the first base station performing the secondary addition procedure, one of the two radio bearers can be used to carry user plane data to transfer the user plane data to the second base station. When the first base station transfers the user plane data to the secondary base station, if a dedicated bearer establishment request such as voice is received from the network side, the voice data is carried by the other one of the two radio bearers. Among them, the user plane data can refer to the data virtualized by the core network or the real data required by the terminal.

[0119] In an example, as Figure 6 shown, the process of the first base station controlling the execution of the first process and the second process includes:

[0120] Step 601: The terminal accesses the first base station.

[0121] Step 602: After the terminal accesses the first base station, the first base station sends a radio bearer establishment request to the network side to request the establishment of two radio bearers.

[0122] Here, the first base station can request the network side to establish two identical radio bearers; it can also request the network side to establish two different radio bearers; it can also request the network side to modify the default bearer to a voice bearer and re - establish a radio bearer.

[0123] Step 603: The first base station executes the first process based on one of the two radio bearers and executes the second process based on the other one of the two radio bearers.

[0124] Here, taking the first process as the SCG addition process as an example, Figure 7 is the process of the first base station executing the first process, including:

[0125] Step 701: The terminal initiates a random access to the 4G base station.

[0126] Step 702: After the terminal accesses the 4G base station, the 4G base station sends a measurement and control message to the terminal.

[0127] Step 703: The terminal performs B1 measurement on the 5G base station and reports the measurement result to the 4G base station.

[0128] Step 704: Based on the B1 event result, if it is higher than the measurement threshold, the 4G base station triggers the NR secondary carrier addition process.

[0129] Here, taking the second process as the voice dedicated bearer establishment process as an example, the voice dedicated bearer establishment process includes the following three stages:

[0130] The first stage, i.e., the connection establishment stage: It is used to complete the random access process, session establishment process, and SIP registration process.

[0131] The second stage, i.e., the voice call establishment stage: It is used to complete the information interaction of the Session Initiation Protocol (SIP) and the establishment of the QCI1 voice dedicated bearer. Among them, the establishment of the QCI1 voice dedicated bearer includes: The MME sends an ERAB SETUP REQ (QCI1) to the base station, and the base station sends an ERAB SETUP RESP.

[0132] The third stage, i.e., the voice holding stage: It is used to complete the interaction of Real-time Transport Protocol (RTP) voice packets.

[0133] Here, the first base station controls the execution of the first process and the second process, which has the following advantages:

[0134] (1) By establishing two radio bearers (such as two QCI9s) at the initial stage of the UE accessing the network, it is possible to ensure the user experience while completely avoiding process conflicts.

[0135] (2) It can solve the problem that the voice service interruption or fallback to 2G affects the user experience due to the conflict between the voice service and the secondary carrier addition process in the NSA network.

[0136] Adopting the technical solution provided by the embodiment of the present invention, after the terminal accesses the first base station, the first base station can actively send a radio bearer establishment request to the network side; the radio bearer establishment request is used to request the network side to establish two radio bearers; subsequently, the first base station can control the execution of the first process and the second process based on the two radio bearers to avoid the occurrence of the problem that the establishment of the dedicated radio bearer fails due to the conflict between the two processes.

[0137] The embodiment of the present invention also provides a radio bearer control method, which is applied to the first base station, as Figure 8 shown, the method includes:

[0138] Step 801: Receive the first parameter sent by the network side;

[0139] Step 802: Based on the first parameter, control the execution of the first process and the second process; the first parameter characterizes the type of the dedicated radio bearer requested to be established by the network side.

[0140] Among them, the first process is used for the first base station to control the terminal to establish a connection with the second base station; the first base station is the master base station, and the second base station is the secondary base station; the second process is used for the first base station to establish a dedicated radio bearer.

[0141] Here, in step 801, if the terminal initiates a dedicated bearer establishment request such as for voice, the network side may send a dedicated bearer establishment request to the first base station; the dedicated bearer establishment request carries the first parameter. Among them, the first parameter may specifically refer to the QCI parameter.

[0142] Here, in step 802, the first process may refer to the secondary carrier addition process, and the second process may refer to the voice dedicated bearer establishment process. During the process of the first base station triggering the secondary carrier addition process, when the first base station transfers user plane data to the secondary base station, if it receives a dedicated bearer establishment request sent by the network side and determines that the terminal initiates a specific bearer such as a voice dedicated bearer according to the first parameter carried in the dedicated bearer establishment request, it may suspend the secondary carrier addition process and execute the voice dedicated bearer establishment process. In this way, it is possible to avoid the problem of voice dedicated bearer establishment failure caused by conflicts between the two processes in the related art.

[0143] The following will detail how to control the execution of the first process and the second process.

[0144] In practical applications, during the process of the first base station triggering the secondary carrier addition process, when the first base station transfers user plane data to the secondary base station, if the terminal initiates a voice service, the first base station may receive a dedicated bearer establishment request sent by the network side; the dedicated bearer establishment request carries the first parameter.

[0145] Based on this, in an embodiment, the receiving of the first parameter sent by the network side includes:

[0146] Receiving a dedicated bearer establishment request sent by the network side; the dedicated bearer establishment request carries the first parameter.

[0147] Among them, the first parameter may specifically refer to the QCI type of the dedicated radio bearer requested to be established by the network side.

[0148] For example, in the NSA network architecture, after the S1 context is established, that is, after the terminal accesses the first base station, the first base station may send a B1 measurement and control message to the UE and trigger the secondary carrier addition process according to the B1 measurement result reported by the UE. During this period, if the user initiates a service, the MME of the network side sends a dedicated bearer establishment request to the first base station. For example, an ERAB SETUPREQ message, which carries the type of QCI.

[0149] In actual application, during the process of the first base station triggering the secondary carrier addition process, when the first base station transfers user plane data to the secondary base station, if it is determined that the terminal initiates a specific bearer such as a voice bearer, the first base station may suspend the current secondary carrier addition process and execute the voice bearer establishment process; if it is determined that the terminal does not initiate a specific bearer such as a voice bearer, the first base station may continue to execute the current secondary carrier addition process.

[0150] Based on this, in an embodiment, the first parameter is a QCI parameter; based on the first parameter, controlling the execution of the first process and the second process includes:

[0151] When the QCI parameter value is equal to a first preset value, suspend the first process and execute the second process;

[0152] When the QCI parameter value is equal to a second preset value, continue to execute the first process;

[0153] Wherein, the first preset type is different from the second preset type.

[0154] For example, the MME on the network side sends a dedicated bearer establishment request to the first base station. For example, an ERAB SETUP REQ message, which carries the type of QCI. If QCI = 1, that is, the user initiates a voice service, the secondary carrier addition process is suspended, and the secondary carrier addition process is resumed after the voice service is established. If QCI ≠ 1, the secondary carrier addition process is carried out normally.

[0155] In an example, as Figure 9 shown, the process of the first base station controlling the execution of the first process and the second process includes:

[0156] Step 901: The terminal accesses the first base station.

[0157] Step 902: After the terminal accesses the first base station, the first base station receives the dedicated bearer establishment request sent by the network side; the dedicated bearer establishment request carries the first parameter.

[0158] Step 903: Based on the first parameter, control the execution of the first process and the second process.

[0159] Here, the first parameter may specifically refer to the QCI type of the dedicated radio bearer requested to be established by the network side. When the QCI parameter value is equal to a first preset value, suspend the first process and execute the second process; when the QCI parameter value is equal to a second preset value, continue to execute the first process.

[0160] Here, the first base station controlling the execution of the first process and the second process has the following advantages:

[0161] (1) By combining the QCI parameters sent by the network side at the initial stage of the UE accessing the network, it is possible to ensure the user experience while completely avoiding process conflicts.

[0162] (2) It can solve the problem that the voice service and the secondary carrier addition process conflict in the NSA network, resulting in the interruption of the voice service or the fallback to 2G, which affects the user experience.

[0163] Adopt the technical solution of the embodiment of the present invention to receive the first parameter sent by the network side; based on the first parameter, control the execution of the first process and the second process; the first parameter represents the type of dedicated radio bearer requested to be established by the network side. Subsequently, the first base station can control the execution of the first process and the second process based on the first parameter to avoid the problem of the dedicated radio bearer establishment failure caused by the conflict between the two processes.

[0164] The embodiment of the present invention also provides a radio bearer control method, which is applied to the first base station, as Figure 10 shown, the method includes:

[0165] Step 1001: Send a radio bearer establishment request to the network side; the radio bearer establishment request is used to request the network side to establish two radio bearers;

[0166] Step 1002: Receive the first parameter sent by the network side; the first parameter represents the type of radio bearer requested to be established by the network side;

[0167] Step 1003: Based on the two radio bearers and the first parameter, control the execution of the first process and the second process.

[0168] Among them, the first process is used for the first base station to control the terminal to establish a connection with the second base station; the first base station is the master base station, and the second base station is the secondary base station; the second process is used for the first base station to establish a dedicated radio bearer.

[0169] Here, in step 1001, by actively requesting the network side to establish two radio bearers, the first base station can simultaneously meet the needs of the terminal to establish a dual connection and the needs of the terminal to initiate a dedicated bearer such as voice. That is to say, during the process of the first base station triggering the secondary carrier addition process, when the first base station transfers the user plane data to the secondary base station, if it receives a voice or other dedicated bearer establishment request sent by the network side, then subsequently, based on the two radio bearers, it can control the execution of the first process and the second process, thereby avoiding the problem of the voice dedicated bearer establishment failure.

[0170] Here, in step 1002, if the terminal initiates a dedicated bearer establishment request such as a voice request, the network side may send a dedicated bearer establishment request to the first base station; the dedicated bearer establishment request carries the first parameter. Among them, the first parameter may specifically refer to the QCI parameter.

[0171] Here, in step 1003, the first process may refer to a secondary carrier addition process, and the second process may refer to a voice dedicated bearer establishment process. During the process of the first base station triggering the secondary carrier addition process, when the first base station transfers user plane data to the secondary base station, if it receives a dedicated bearer establishment request sent by the network side and determines, based on the first parameter, that the terminal initiates a specific bearer such as a voice dedicated bearer, it may transfer the user plane data through one of the two radio bearers and establish voice through the other radio bearer. In this way, the requirements for the terminal to establish a dual connection and the requirements for the terminal to initiate a dedicated bearer such as voice can be satisfied simultaneously.

[0172] Adopting the technical solution of the embodiment of the present invention, the first base station may actively send a radio bearer establishment request to the network side; subsequently, based on the two established radio bearers, control the execution of the first process and the second process to avoid the problem of failure in establishing a dedicated radio bearer caused by a conflict between the two processes. And / or, after the terminal accesses the first base station, the first base station may receive the first parameter sent by the network side; subsequently, based on the first parameter, control the execution of the first process and the second process to avoid the problem of failure in establishing a dedicated radio bearer caused by a conflict between the two processes.
