Description
[ technical field ] A method for producing a semiconductor device
The present invention relates to the field of communications technologies, and in particular, to a service sending method and a base station.
[ background of the invention ]
5G networks are continuously developed, and 5G voice service solutions are also configured and deployed based on the 5G network conditions, and currently, there are 3 solutions, namely dual connectivity, fallback LTE, and handover LTE.
And (3) fallback to LTE: the method is used for a single standby terminal, resides in 5G at ordinary times, is switched to LTE when a voice call is initiated, and provides voice service through LTE bearing. In the early and middle 5G deployment, 5G NR hot-spot coverage, 5GC has already started deployment. To avoid frequent handovers when 5G is not yet able to provide voice services, or when 5G coverage is insufficient. The terminal normally resides on 5G and carries out IMS registration, when a voice call is initiated, the 5G RAN initiates a fallback flow, and the terminal is switched to LTE to continue a call establishment flow. This scheme is also known as EPS Fallback. This scheme allows 5G terminals to reside in the 5G NR using data traffic while voice traffic is still carried over LTE. The scheme is suitable for serving as a voice solution covered by NR hot spots in the initial stage of 5G deployment so as to avoid voice interruption caused by frequent switching from influencing user experience.
And switching LTE: the terminal facing the single standby terminal, 5G NR accesses to 5GC, LTE accesses to EPC, and both can provide voice and 5G/LTE voice switching. This scheme is used for the 5GC and EPC coexistence phase. In the middle and later stages of 5G deployment, the 5G NR forms a continuous coverage, and 5GC has been deployed on a large scale. Voice services can be provided through both 5G and LTE. Normally, the single standby terminal resides on 5G, and when the 5G signal is not good, voice and data are switched from 5G to 4G. This scheme is also commonly referred to as VoNR. VoNR is a technical solution for carrying voice through 5G NR, and voice is switched to LTE at the boundary of NR. The scheme is used after 5G large-scale deployment, and has the advantages of better user experience because the call setup time is short and the data service can still be transmitted at high speed, and is a target voice scheme.
Double connection: the terminal supports double connection, the control plane is anchored in LTE, and the terminal registers in IMS through LTE to provide voice service. The scheme is used for an option 3 mode, the terminal is simultaneously accessed to LTE and 5G NR through double connection, a control plane is anchored in an EPC core network, and the terminal is registered to an IMS through the EPC to use voice services. Because the terminal can simultaneously support data transceiving of 5G and 4G, voice service can be selectively carried on LTE (voice service can not be carried on a 5G base station), and data service is continuously carried on 5G. The scheme of voice service is still substantially VoLTE scheme at this time. The scheme can be used as a transition scheme between a core network and a wireless network in the initial 5G deployment stage, and meets the operation mode that the 5G network constructed in the initial stage of an operator only realizes the improvement of the MBB bandwidth of an individual user.
In the dual connection mode, there are two schemes for the cooperation of the 5G data service and the VoLTE voice service, wherein the two schemes have advantages and disadvantages, one is the concurrence of the 5G data service and the VoLTE voice service, and the other is the mutual exclusion of the 5G data service and the VoLTE voice service.
The concurrence of the 5G data service and the VoLTE voice service is realized, and the defects that the voice uplink power loss is 3dB and the voice quality can not be guaranteed at the coverage edge are overcome. Mutual exclusion of 5G data service and VoLTE voice service is realized, namely NR auxiliary carrier waves are directly deleted when the VoLTE voice service is carried out, and the voice service and the data service are only established in 4G. The advantage is that the edge user speech perception is higher, and the disadvantage is that the rate advantage of NSA is lost in better coverage environment.

[ detailed description ] embodiments
For better understanding of the technical solutions of the present invention, the following detailed descriptions of the embodiments of the present invention are provided with reference to the accompanying drawings.
It should be understood that the described embodiments are only some embodiments of the invention, and not all 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.
The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
It should be understood that the term "and/or" as used herein is merely one type of associative relationship that describes an associated object, meaning that three types of relationships may exist, e.g., A and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
The technical scheme disclosed by the application is used for an NSA (Non-Standard one) architecture, and the NSA architecture is a scheme for the transition from a 4G network to a 5G network integrally. In the NSA architecture, 4G and 5G are concurrent. In a mobile communication network, there are layer-by-layer relationships such as a core network, a base station, a mobile phone terminal, and the like. The core network refers to the entire communication network, and the base station is one of elements constituting the core network. In the 4G era, the core network is a 4G network, the base station is also a 4G base station, and the mobile phone terminal is also a 4G antenna, which is a standard 4G network. In the NSA non-independent networking scheme, the core network may be a 4G network, or may be a 5G network, and the base station may be a 4G base station or a 5G base station, so that many networking methods exist.
The voice solution of the NSA architecture applies a dual connection mode, and the cooperation of data service and VoLTE voice service in the NSA architecture has two schemes.
Referring to fig. 1A, specifically, a communication diagram of a terminal when a VoLTE voice service and a data service are concurrent is shown, where the terminal 102 is a device supporting dual connectivity, that is, can communicate with a 4G base station 104 and a 5G base station 106 at the same time. It should be noted that, in the dual connectivity mode, the VoLTE voice traffic can only be carried through the 4G base station 104, and the data traffic can be carried through the 4G base station 104 and/or the 5G base station 106. The terminal VoLTE voice service and the data service are concurrent, that is, the VoLTE voice service is carried by the 4G base station, and the 5G data service is distributed to the user plane data by the 5G base station 106. However, it should be noted that when the VoLTE voice service is concurrent with the 5G data service, the uplink power loss of the VoLTE voice service is 3dbm, and the voice quality at the coverage edge cannot be guaranteed.
Referring to fig. 1B, specifically, a communication schematic diagram when a VoLTE voice service and a 5G data service are mutually exclusive is provided, where a terminal 102 is a device supporting dual connection, that is, may communicate with a 4G base station 104 and a 5G base station 106 at the same time, it should be noted that, in the scheme that the VoLTE voice service and the 5G data service are mutually exclusive, when the terminal 102 performs the VoLTE voice service, the data service may not be split through the 5G base station 106, that is, the data service and the VoLTE voice service may only be performed through the 4G base station. That is, the terminal 102 may directly delete the NR auxiliary carrier during the VoLTE voice service, and only establish the voice service and the data service in the 4G base station 104.
In order to solve the above technical problem, the present application provides a service sending method, which can be applied to a 4G base station, specifically referring to fig. 2, and specifically relates to a flowchart of a service sending method provided in an embodiment of the present invention, where the method includes:
step 202: the 4G base station acquires first target information indicating channel quality between the 4G base station and a target terminal
It should be noted that, in an initial state during the execution of the method, the VoLTE voice service of the target terminal and the 5G data service are in a concurrent state, that is, the data service is shunted through the 5G base station.
The first target information includes, but is not limited to, SINR (Signal to Interference plus Noise Ratio) value, RSRP (Reference Signal Receiving Power) value, and the like.
The 4G base station may obtain the first target information in real time, and determine the channel quality between the 4G base station and the target terminal according to the information.
Step 204: the 4G base station judges whether the first target information meets a first preset condition or not
Determining whether the first target information meets a first preset condition may include comparing the first target information with a first preset threshold, and if the first target information is greater than or equal to the first preset threshold, it indicates that the channel quality between the 4G base station and the target terminal is good, and if the first target information is less than the first preset threshold, for example, an SINR value or an RSRP value is less than the first preset threshold, it indicates that the channel quality between the 4G base station and the target terminal is not good.
In one embodiment, it is determined whether a duration that the first target information is smaller than a first preset threshold is longer than a certain duration, and if the duration that the first target information is smaller than the first preset threshold is longer than the certain duration, it indicates that the channel quality between the 4G base station and the target terminal is not good. That is, whether the duration of the first target information being continuously smaller than the first preset threshold is too long or not, and the duration of the first target information being continuously smaller than the first preset threshold is too long, which indicates that the channel quality between the 4G base station and the target terminal is not good, thereby further improving the judgment precision.
Step 206: if the first target information meets the first preset condition, the 4G base station sends a first instruction to the target terminal, so that the target terminal is disconnected with the second base station based on the first instruction, and the target terminal sends the second service to the first base station
If the first target information meets the first preset condition, for example, the first target information is smaller than a first preset threshold, that is, the channel quality between the 4G base station and the target terminal is not good. At this time, the improvement of the call quality of the VoLTE voice service may be prioritized, the 4G base station may send an instruction for disconnecting the terminal from the 5G base station to the terminal, the terminal may disconnect the 5G base station after receiving the instruction sent by the 4G base station, and the 4G base station may simultaneously carry the data service and the VoLTE voice service.
Step 208: the 4G base station acquires first target information
Specifically, the step 208 of acquiring the first target information is to determine the channel quality between the 4G base station and the target terminal again. In one embodiment, the 4G base station may periodically acquire the first target information to determine the channel quality between the 4G base station and the target terminal.
Step 210: the 4G base station judges whether the first target information meets a second preset condition, if the first target information meets the second preset condition, a first request is sent to the target terminal, the first request is used for the target terminal to obtain second target information, and the second target information indicates the channel quality between the target terminal and the second base station
As already shown above, determining whether the first target information meets the first preset condition may include comparing the first target information with a first preset threshold, and if the first target information is greater than or equal to the first preset threshold, indicating that the channel quality between the 4G base station and the target terminal is good, and if the second target information is less than a second preset threshold, for example, an SINR value or an RSRP value is less than the first preset threshold, indicating that the channel quality between the 4G base station and the target terminal is not good.
In one embodiment, it is determined whether a duration that the first target information is greater than or equal to a first preset threshold is greater than a certain duration, and if the duration that the first target information is greater than or equal to a second preset threshold is greater than the certain duration, it is determined that the channel quality between the 4G base station and the target terminal is good. That is, whether the duration of the first target information which is continuously greater than or equal to the first preset threshold is too long or not, and the duration of the first target information which is continuously greater than or equal to the second preset threshold is too long, indicates that the channel quality between the 4G base station and the target terminal is good, and further improves the judgment precision.
In one embodiment, when the 4G base station determines that the channel quality between the 4G base station and the target terminal is good, a B1 measurement may be issued to the target terminal, where the B1 measurement is used for enabling the target terminal to obtain second target information, where the second target information indicates the channel quality between the target terminal and the 5G base station, and the second target information includes an SINR value or an RSRP value of the 5G base station, and the like.
In one embodiment, the terminal may determine whether the channel quality between the target terminal and the 5G base station is better based on the second target information, for example, by comparing the SINR value with a second preset threshold value to determine the channel quality between the target terminal and the 5G base station. If the terminal judges that the channel quality between the target terminal and the 5G base station is better, the terminal can establish connection with the 5G base station, so that the 5G base station can shunt data services again, and the transmission rate of data is increased.
In another embodiment, the terminal may transmit the second target information to the 4G base station.
Step 212: and the 4G base station receives the second target information sent by the terminal, judges whether the second target information meets the third preset condition, and sends a second instruction to the second base station if the third target information meets the third preset condition, so that the second base station establishes connection with the target terminal based on the second instruction, and the target terminal sends the second service to the second base station.
In one embodiment, the 4G base station may determine whether the channel quality between the target terminal and the 5G base station is better based on the second target information, for example, by comparing the SINR value with a second preset threshold value to determine the channel quality between the target terminal and the 5G base station. If the SINR value is greater than or equal to the second preset threshold, which indicates that the channel quality between the target terminal and the 5G base station is good, an instruction may be sent to the 5G base station, so that the 5G base station establishes a connection with the terminal, and the 5G base station shunts the terminal data traffic again, thereby increasing the data transmission rate.
In one embodiment, the 4G base station may determine whether the channel quality between the target terminal and the 5G base station is better based on the second target information, for example, by comparing the SINR value with a second preset threshold value to determine the channel quality between the target terminal and the 5G base station. If the 4G base station judges that the channel quality between the target terminal and the 5G base station is good, an instruction can be sent to the terminal, so that the terminal actively establishes connection with the 5G base station, the 5G base station shunts terminal data services again, and the transmission rate of data is increased.
