Description

Technical Field

[0001] The present invention relates to the field of wireless technology, and particularly to a method and device for processing voice services. Background Art

[0002] The 5G SA network currently adopts the EPS Fallback voice solution, where the user terminal falls back to the 4G network for calls and then quickly returns to the 5G network from the 4G network after the call ends. However, at present, the 5G spectrum resources are limited, and both the 5G private network and the 5G public network are deployed on 2.6 GHz. When the user terminal quickly returns, it is easy to be redirected to the 5G public network, affecting the user experience.

[0003] Currently, the 5G high-speed rail private network and the public network use the same frequency for networking. Although the frequency domain position of the high-speed rail SSB has been misaligned from 6312 of the public network to 6339, enabling the network side and the terminal side to accurately identify the high-speed rail private network, affected by the terminal mechanism, when SA users initiate FastReturn to redirect back to the 5G network from the 4G network after a voice call ends, they still rank the redirected frequency points and the prior frequency points together for RSSI sorting, that is, search in the order of superiority and inferiority after sorting the frequency point quality. When there is a strong public network area on the high-speed rail line, it is very easy for the terminal to Fast Return back to the 5G public network cell. Due to the high-speed movement characteristics of the high-speed rail, the coverage range of the private network cell is often long, with an average cell spacing of about 2 kilometers, while the coverage range of the public network cell is short. The train passes through multiple cells in a short time, resulting in frequent handovers and even fast fading and network disconnection, which has a greater impact on the user experience.

[0032] Figure 3 is a schematic structural diagram of the electronic device provided by the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without making creative efforts fall within the protection scope of the present invention.

[0034] Figure 1 is a schematic flowchart of the voice service processing method provided by the present invention. Referring to Figure 1 , the voice service processing method provided by the present invention may include:

[0035] S110. By adjusting the first parameter in the neighboring cell and 4 / 5G interworking strategy, cause the 5G terminal to fallback to the 4G anchor point of the 4G private network when initiating a voice service;

[0036] S120. By adjusting the second parameter in the 4 / 5G interworking strategy, cause the 5G terminal to camp on the 4G anchor point of the 4G private network during a call;

[0037] S130. By adjusting the third parameter in the 4 / 5G interworking strategy, cause the 5G terminal to camp on the 5G private network after the call ends.

[0038] It should be noted that the execution subject of the voice service processing method provided by the present invention may be an electronic device, a component in the electronic device, an integrated circuit, or a chip. The electronic device may be a mobile electronic device or a non-mobile electronic device. Exemplarily, the mobile electronic device may be a mobile phone, a tablet computer, a laptop computer, a handheld computer, a vehicle-mounted electronic device, a wearable device, an ultra-mobile personal computer (UMPC), a netbook, or a personal digital assistant (PDA), etc. The non-mobile electronic device may be a server, a Network Attached Storage (NAS), a personal computer (PC), a television (TV), a teller machine, or a self-service machine, etc. The present invention does not make specific limitations.

[0039] Specifically, a private network refers to a professional network that realizes network signal coverage in a specific area and provides communication services for specific users in aspects such as organization, command, management, production, and dispatching. In short, a private network is a mobile communication network dedicated to a specific industry or enterprise. In life, when people make phone calls or browse information on the web using their mobile phones, they rely on the public communication network (i.e., the public network). The 2 / 3 / 4 / 5G mobile communication networks to which our smartphones are connected are called public networks. A public network is a "public place" where hundreds of millions of users share the same network, the same frequency band resources, and network equipment.

[0040] EPS Fallback means that 5G NR does not support voice services. When a user equipment (UE) initiates or receives a voice call in 5G NR, it falls back to the 4G network through redirection or handover, and VoLTE provides voice services. After the voice call ends, the UE returns to the 5G network.

[0041] In step S110, by adjusting the first parameter in the neighbor cell and 4 / 5G interworking strategy, the 5G terminal falls back to the 4G anchor point of the 4G private network when initiating a voice service. When the 5G terminal initiates or receives a voice service in 5G NR, it will fall back to the 4G network through redirection or handover. By adjusting the neighbor cells of the private network 5G cell, for example, adding the 4G cell of the private network on the same frequency band as the neighbor cell of the private network 5G cell, and at the same time adjusting the first parameter in the 4 / 5G interworking strategy, the 5G terminal falls back to the 4G network through handover, and when performing cell handover, it only switches to the 4G cell of the private network on the same frequency band. The 4G cell of the private network on the same frequency band is the 4G anchor point.

[0042] In step S120, by adjusting the second parameter in the 4 / 5G interworking strategy, the 5G terminal stays in the 4G anchor point of the 4G private network during the call. During the call, the 5G terminal is provided with voice services by VoLTE, and cell handover also occurs during the call. By adjusting the second parameter in the 4 / 5G interworking strategy, the 5G terminal only switches between the 4G cells of the private network on the same frequency band during the call, so that the 5G terminal always stays in the 4G anchor point of the 4G private network during the call.

[0043] In step S130, by adjusting the third parameter in the 4 / 5G interworking strategy, the 5G terminal stays in the 5G private network after the call ends. The 5G terminal always stays in the 4G anchor point of the 4G private network during the call. After the call ends, by borrowing the 4G anchor point of the private network and adjusting the third parameter in the 4 / 5G interworking strategy, the 5G terminal returns to the 5G private network after the call ends.

[0044] The voice service processing method provided by the present invention enables a 5G terminal to fall back to a 4G anchor point in a 4G private network when initiating or receiving a voice service by adjusting the neighboring cell and 4 / 5G interworking policies, and to always camp on the 4G anchor point in the 4G private network during a call. By borrowing the 4G anchor point, the 5G terminal camps on the 5G private network after the call ends, solving the technical problem that 5G terminals are prone to be directed to the public network during Fast Return, and improving the user experience.

[0045] In one embodiment, the adjustment of the first parameter in the neighboring cell and 4 / 5G interworking policies includes:

[0046] Modifying the inter-system handover parameters of the New Radio (NR) cell and modifying the NR cell-level algorithm switch, and adding only the private network 4G FDD1800 cell as a neighboring cell of the private network 5G cell.

[0047] Specifically, when a 5G terminal initiates or receives a voice service in 5G NR, it will fall back to the 4G network through redirection or handover. By modifying the inter-system handover parameters of the New Radio (NR) cell, the EPS FallBack mode is configured as handover; by modifying the NR cell-level algorithm switch, the voice policy switch EPS FallBack strongest neighboring cell redirection switch is configured to be off; and only the private network 4G FDD1800 cell is added as a neighboring cell of the private network 5G cell.

[0048] Through the combination of the above three policies, the 5G terminal falls back to the 4G network through handover, and when performing cell handover, the 5G terminal will only hand over to the private network 4G FDD1800 cell, which can ensure that the user terminal falls back to the 4G anchor point in the private network during EPS Fallback.

[0049] The voice service processing method provided by the present invention enables a 5G terminal to fall back to the 4G network through handover by adjusting the first parameter in the neighboring cell and 4 / 5G interworking policies, and when performing cell handover, the 5G terminal will only hand over to the private network 4G FDD1800 cell, which can ensure that the user terminal falls back to the 4G anchor point in the 4G private network during EPS Fallback.

[0050] In one embodiment, the adjustment of the second parameter in the 4 / 5G interworking policy to enable the 5G terminal to camp on the 4G anchor point in the 4G private network during a call includes:

[0051] Modifying the inter-frequency handover parameter group of the private network 4G anchor point cell for voice services, configuring the A2 event trigger threshold and the A4 / A4 event trigger threshold, so that the 5G terminal only performs intra-frequency handover during a call, thereby camping on the 4G anchor point in the 4G private network.

[0052] Specifically, during a call, the 5G terminal provides voice services through VoLTE. Cell handover also occurs during the call. By adjusting the second parameter in the 4 / 5G interworking policy, that is, modifying the inter-frequency handover parameter group of the private network 4G anchor cell for voice services (QCI = 1).

[0053] A2 event: The measurement threshold is enabled. That is, when the RSRP of the serving cell measured by the UE is less than this threshold value, inter-frequency measurement is enabled. The A2 event is used to start inter-frequency and inter-system measurements.

[0054] A4 event: It is also a handover event. That is, if the RSRP value of the inter-frequency neighbor cell measured by the UE is greater than this threshold, the UE starts to hand over to this inter-frequency neighbor cell. The A4 event is used to indicate that the quality of the neighbor cell is higher than the specified absolute threshold.

[0055] A5 event: The quality of service of the serving cell is lower than an absolute threshold 1, and the quality of service of the neighbor cell is higher than an absolute threshold 2, triggering the A5 event handover. The A5 event is used to indicate that the quality of the serving cell is lower than the specified absolute threshold, and at the same time, the quality of the adjacent cell is higher than the specified absolute threshold.

[0056] By configuring a lower A4 / A5 inter-frequency A2 RSRP trigger threshold, the difficulty of triggering the A2 event is increased, and the start of inter-frequency measurement is delayed; and by configuring a higher inter-frequency RSRP trigger threshold based on coverage, the difficulty of triggering the A4 / A5 event is increased, and inter-frequency handover is delayed.

[0057] Through the combination of the above two strategies, while delaying the start of inter-frequency measurement, inter-frequency handover is also delayed, so that the 5G terminal only performs handovers between private network 4G cells on the same frequency point during a call, that is, it is ensured that the 5G terminal only performs intra-frequency handovers during a call and always camps on the 4G anchor of the 4G private network.

[0058] The voice service processing method provided by the present invention delays the start of inter-frequency measurement and inter-frequency handover by adjusting the second parameter in the 4 / 5G interworking policy, so that the 5G terminal only performs intra-frequency handovers during a call, thereby camping on the 4G anchor of the 4G private network.

[0059] In one embodiment, the adjustment of the third parameter in the 4 / 5G interworking policy includes:

[0060] Modifying the cell-level algorithm extension switch, modifying the NR secondary cell group (SCG) frequency point configuration, modifying the inter-system handover to NR parameter group, and modifying the cell handover parameter configuration.

[0061] Specifically, the 5G terminal always resides on the 4G anchor point of the 4G private network during a call. After the call ends, it needs to fall back to the 5G network. By borrowing the 4G anchor point of the private network and adjusting the third parameter in the 4 / 5G interoperation strategy, the 5G terminal can fall back from the 4G private network to the 5G private network.

[0062] That is, by modifying the cell-level algorithm expansion switch, the situation where the 5G terminal Fast Return returns to the 5G public network cell is avoided.

[0063] B1 event: It means that the quality of the neighboring cell in a different system is higher than a certain threshold. When this condition is met and the event is reported, the terminal reports a measurement report, and the network initiates a handover to a different system.

[0064] B2 event: It means that the quality of the serving cell is lower than a certain threshold and the quality of the neighboring cell in a different system is higher than a certain threshold. The terminal reports a measurement report, and the network initiates a handover to a different system.

[0065] Modify the NR SCG frequency point configuration. For example, a smaller NSA DC B1 event time hysteresis can be configured, or a lower NSA DC B1 event RSRP threshold can be configured. The time hysteresis is the time required to reach the event trigger threshold. By reducing the event time hysteresis or trigger threshold, the difficulty of triggering the NSA DC B1 event is reduced.

[0066] Modify the parameter group for handover to NR in a different system, and configure a larger NR handover B1 / B2 event time hysteresis. By increasing the event time hysteresis, the difficulty of triggering the NR B1 event is increased.

[0067] Modify the cell handover parameter configuration, and configure the NR B1 event time hysteresis adjustment switch in the handover algorithm switch to be off. Since when the switch is on, the overall strategy is to default to the SA 5G network first, which is easy to return to the public network and will result in a poor user experience, so the switch is turned off. When the NR B1 event time hysteresis is greater than the NSA DC B1 event time hysteresis, no adjustment is made to the NSA DC B1 event hysteresis for NSA / SA dual-mode user terminals.

[0068] In one embodiment, the 5G terminal resides on the 5G private network after the call ends, including:

[0069] The 5G terminal preferentially adds an SCG after the call ends and resides on the non-standalone networking NSA 5G private network;

[0070] When the time hysteresis for meeting the NR B1 event is satisfied, the 5G terminal resides on the standalone networking SA 5G private network.

[0071] Specifically, due to the configuration of a lower NSA DC B1 event time hysteresis and a larger NR handover B1 / B2 event time hysteresis, the NSA DC B1 event time hysteresis is less than the NR handover B1 / B2 event time hysteresis. When the 5G terminal ends a call and meets the RSRP threshold of the NSA DC B1 event, it first meets the time hysteresis of the NSA DC B1 event, and the 5G terminal preferentially adds the SCG and camps on the non-standalone NSA 5G private network. After meeting the time hysteresis of the NR B1 event, the 5G terminal then camps on the standalone SA 5G private network.

[0072] Through the combination of the above strategies, it is ensured that the 5G terminal preferentially adds the SCG and camps on the NSA 5G private network after the call ends, and then moves to the SA 5G private network when the time hysteresis of the NR B1 event is met.

[0073] The voice service processing method provided by the present invention adjusts the third parameter in the 4 / 5G interworking strategy, enabling the 5G terminal to preferentially add the SCG and camp on the NSA 5G private network after the call ends, and then move to the SA 5G private network when the time hysteresis of the NR B1 event is met, improving the user experience.

[0074] In one embodiment, modifying the cell-level algorithm extension switch includes:

[0075] Closing the fast return switch from the 4G access network E-UTRAN to the 5G access network NG-RAN in the handover permission switch.

[0076] Specifically, by closing the fast return switch from the 4G access network E-UTRAN to the 5G access network NG-RAN in the handover permission switch, the situation where the 5G terminal Fast Return quickly falls back to the 5G public network cell is avoided.

[0077] The voice service processing method provided by the present invention avoids the situation where the 5G terminal Fast Return returns to the 5G public network cell by modifying the cell-level algorithm extension switch.

[0078] In one embodiment, modifying the NR SCG frequency point configuration includes:

[0079] Configuring the NSA DC B1 event trigger threshold and the NSA DC B1 event time hysteresis.

[0080] Specifically, modifying the NR SCG frequency point configuration, by configuring a lower NSA DC B1 event RSRP threshold and a smaller NSA DC B1 event time hysteresis, where the time hysteresis is the duration required to reach the event trigger threshold, and at the same time reducing the event trigger threshold and the time hysteresis, greatly reduces the difficulty of triggering the NSA DC B1 event.

[0081] The voice service processing method provided by the present invention greatly reduces the difficulty of triggering the NSA DC B1 event by simultaneously configuring a lower RSRP threshold for the NSA DC B1 event and a smaller time hysteresis for the NSA DC B1 event, enabling the 5G terminal to preferentially add the SCG after the call ends and camp on the NSA 5G private network.

[0082] In one embodiment, the voice service processing method provided by the present invention may include:

[0083] Step S1, adjust the neighbor cell and 4 / 5G interworking strategy to make the 5G terminal's EPS Fallback fall back to the 4G anchor point:

[0084] Modify the inter-system handover parameters of the NR cell and configure the EPS FB mode as handover;

[0085] Modify the algorithm switch at the NR cell level and configure the voice policy switch and the EPS FB strongest neighbor cell redirection switch to be off;

[0086] Only add the private network 4G FDD1800 cell as a neighbor cell of the private network 5G cell.

[0087] Through the combination of the above three strategies, ensure that the 5G terminal falls back to the 4G anchor point of the private network during EPS Fallback.

[0088] Step S2, adjust the 4 / 5G interworking strategy to make the 5G terminal only perform intra-frequency handovers during the call:

[0089] Modify the inter-frequency handover parameter group of the private network 4G anchor point cell for voice services (QCI = 1), configure a lower A2 RSRP trigger threshold based on A4A5 inter-frequency to increase the difficulty of triggering the A2 event and delay the start of inter-frequency measurement; configure a higher inter-frequency RSRP trigger threshold based on coverage to increase the difficulty of triggering the A4 / A5 event and delay the inter-frequency handover.

[0090] Through the combination of the above two strategies, ensure that the 5G terminal only performs intra-frequency handovers during the call and always camps on the 4G anchor point.

[0091] Step S3, adjust the 4 / 5G interworking strategy to make the 5G terminal go to NSA first and then to SA after the call ends:

[0092] Modify the extended switch of the cell-level algorithm and turn off the fast return switch from E-UTRAN to NG-RAN in the handover permission switch;

[0093] Modify the NR SCG frequency point configuration, configure a lower RSRP threshold for the NSA DC B1 event and a smaller time hysteresis for the NSA DC B1 event, and reduce the difficulty of triggering the NSA DC B1 event;

[0094] Modify the parameters for inter-system handover to NR, configure a larger time hysteresis for the NR handover B1 / B2 events, and increase the difficulty of triggering the NR B1 event;

[0095] Modify the cell handover parameter configuration, configure the NR B1 event time hysteresis adjustment switch in the handover algorithm switch to off. When the NR B1 event time hysteresis is greater than the NSA DC B1 event time hysteresis, no adjustment is made to the NSA DC B1 event hysteresis for NSA / SA dual-mode user terminals.

[0096] Through the combination of the above four strategies, ensure that the user terminal preferentially adds an SCG to camp on the NSA 5G private network after a call ends, and then switches to the SA 5G private network when the time hysteresis for the NR B1 event is met.

[0097] Before and after the application of the voice service processing method provided by the present invention, the situation of the 5G terminal returning to the 5G network after an EPS Fallback call ends is shown in Table 1:

[0098] Table 1 Return situation of 5G terminal after a call ends before and after the application of the voice service processing method

[0099]

[0100] The voice service processing method provided by the present invention enables the user terminal to fall back to the 4G anchor point of the private network during EPS Fallback by adjusting the neighboring cell and interoperability strategies, allows the user terminal to only perform intra-frequency handovers during the call and always camp on the 4G anchor point by the interoperability strategy, and closes Fast Return. By the interoperability strategy, after the user's call ends, the user terminal first goes to the NSA 5G private network and then to the SA 5G private network, always camping on the 5G private network, solving the technical problem of being easily directed to the public network during Fast Return and improving the user experience.
