[0031] Furthermore, the accompanying drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted. Some block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0032] The flowcharts shown in the accompanying drawings are merely illustrative and do not necessarily include all steps. For example, some steps may be broken down, while others may be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances. Furthermore, all terms such as "first," "second," and "third" used below are for distinction purposes only and should not be construed as limiting the scope of this disclosure.

[0033] In the exemplary embodiments of this disclosure, the terminal is UE (User Equipment), and may also be referred to as terminal equipment, access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, wireless communication equipment, user agent, or user device. The terminal may also be a cellular phone, cordless phone, Session Initiation Protocol (SIP) phone, Wireless Local Loop (WLL) station, Personal Digital Assistant (PDA), handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, vehicle-mounted device, wearable device, terminal equipment in a 5G network, or terminal equipment in a Public Land Mobile Network (PLMN), etc. It may also be an end device, logical entity, smart device, such as a mobile phone, smart terminal, or Internet of Things (IoT) device. This disclosure does not limit the scope of the embodiments.

[0034] A base station, as a network device, has equipment or chips that can be configured to provide random access functionality to terminals. This equipment includes, but is not limited to: evolved Node B (eNB), Radio Network Controller (RNC), Node B (NB), Base Station Controller (BSC), Base Transceiver Station (BTS), home base station (e.g., home-evolved Node B, or home Node B, HNB), Base Band Unit (BBU), Access Point (AP) in a Wi-Fi system, wireless relay node, wireless backhaul node, and Transmission and Reception Point (TRP or Transmission...). Point (TP), etc., can also be a gNB in ​​a 5G, such as NR system, or a transmission point (TRP or TP), one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system, or a network node that constitutes a gNB or transmission point, such as a baseband unit (BBU) or a distributed unit (DU), etc.

[0035] Figure 1 A schematic diagram of a network access system according to an embodiment of the present disclosure is shown. (Reference) Figure 1 The network access system of this disclosure may include a terminal 11 and a base station 12.

[0036] In implementing the network access scheme of this disclosure, terminal 11 can send information to base station 12 regarding whether terminal 11 supports VoNR, and base station 12 can obtain this information. If it is determined that terminal 11 does not support VoNR, base station 12 further determines whether terminal 11 is a roaming terminal of the target network corresponding to base station 12. If it is determined that terminal 11 is a roaming terminal of the target network, then when the RRC (Radio Resource Control) connection is released, base station 12 sends a first RRC connection release message to terminal 11. The first RRC connection release message includes a first dedicated frequency priority, which is used to indicate whether terminal 11 can access the network. That is, terminal 11 can access the network according to the first dedicated frequency priority, and the first dedicated frequency priority does not include the frequency point information of the target network. Therefore, terminal 11 can access other networks besides the target network.

[0037] Additionally, if terminal 11 is not a roaming terminal of the target network, then upon release of the RRC connection, base station 12 can send a second RRC connection release message to terminal 11. This second RRC connection release message includes a second dedicated frequency priority, which is used to instruct terminal 11 to access the network, and the frequency information included in the second dedicated frequency priority is the frequency information of the target network. Therefore, terminal 11 can access the target network.

[0038] If terminal 11 supports VoNR, base station 12 may not need to configure a dedicated priority. Alternatively, it can configure a third dedicated frequency priority, which is used to indicate that terminal 11 is accessing the network and includes frequency information of the target network and other networks.

[0039] In an example of configuring a third dedicated frequency priority, when an RRC connection is released, base station 12 can send a third RRC connection release message to terminal 11. This third RRC connection release message includes the third dedicated frequency priority.

[0040] Figure 2 The following example illustrates how a terminal can access the network, using two different carrier networks as examples. These two carrier networks are denoted as Carrier A's network and Carrier B's network, respectively.

[0041] In an exemplary embodiment of this disclosure, the determination of whether the terminal accesses the network of operator A or the network of operator B is based on whether the terminal supports VoNR and whether it is a roaming terminal of operator A.

[0042] If the terminal supports VoNR, it can determine whether the terminal connects to operator A's network or operator B's network based on frequency priority. Alternatively, it can default to connecting to either operator A's or operator B's network.

[0043] If the terminal does not support VoNR and is a roaming terminal of operator A, the terminal can access the network of operator B.

[0044] If the terminal does not support VoNR and is not a roaming terminal of operator A, the terminal can access operator A's network.

[0045] Figure 3 The diagram illustrates the interaction flowchart between a base station and a terminal according to an embodiment of the present disclosure.

[0046] refer to Figure 3 In step S302, the terminal sends information about its terminal capabilities to the base station; in step S304, the base station can determine an RRC connection release message based on the terminal capability information sent by the terminal, and the RRC connection release message contains a dedicated frequency priority corresponding to the terminal capability; in step S306, the base station sends an RRC connection release message to the terminal so that the terminal can access the network based on the dedicated frequency priority.

[0047] Figure 4 A flowchart illustrating an exemplary embodiment of the network access method of this disclosure is shown schematically. (Reference) Figure 4 The network access method may include the following steps:

[0048] S42. Obtain information sent by the terminal regarding whether the terminal supports the Voice over New Radio (VoNR) service.

[0049] In an exemplary embodiment of this disclosure, the terminal can send information about its terminal capabilities to a base station (hereinafter referred to as a base station) of the target network. Specifically, the terminal can proactively send information about its terminal capabilities to the base station after powering on or restarting. The target network can be any operator's network, and this disclosure does not limit the type of target network.

[0050] After obtaining the terminal capability information sent by the terminal, the base station can determine whether the information includes whether VoNR is supported.

[0051] If the terminal capability information is determined to include whether the terminal supports VoNR, the base station obtains the VoNR support information from the terminal capability information.

[0052] If the terminal capability information does not include whether the terminal supports VoNR, the base station can send a support information reporting instruction to the terminal. This instruction instructs the terminal to report whether it supports VoNR. In other words, the terminal can respond to this support information reporting instruction by reporting to the base station whether it supports VoNR. In this case, the base station can receive the terminal's report regarding its own VoNR support.

[0053] S44. If the terminal does not support VoNR, determine whether the terminal is a roaming terminal of the target network.

[0054] Based on the information received regarding whether the terminal supports VoNR, if the terminal does not support VoNR, the base station can determine whether the terminal is a roaming terminal of the target network.

[0055] Specifically, the base station can obtain the PLMN selected by the terminal and determine whether the terminal is a roaming terminal of the target network based on the selected PLMN. The PLMN information selected by the terminal can be sent to the base station separately by the terminal, or it can be included in the terminal's capability information and sent to the base station by the terminal together.

[0056] S46. If the terminal is a roaming terminal of the target network, when the Radio Resource Control (RRC) connection is released, a first RRC connection release message is sent to the terminal. The first RRC connection release message contains a first dedicated frequency priority. The first dedicated frequency priority is used to indicate that the terminal accesses the network and does not contain frequency point information of the target network.

[0057] In a communication system, a base station can send an RRC connection release message to a terminal to initiate the RRC connection release process. Upon receiving the RRC connection release message, the terminal can release the RRC connection and transition from the RRC connected state to the RRC idle state or the RRC inactive state. For example, the base station can configure an inactivity timer for the terminal, typically set to a duration of 10 or 20 seconds. If the base station detects service transmission, it restarts the timer. If no service transmission is detected, the timer expires. The inactivity timer expiration triggers the base station to send an RRC connection release message to the terminal, and upon receiving the message, the terminal enters the RRC release procedure.

[0058] In an exemplary embodiment of this disclosure, if the terminal is a roaming terminal of the target network, a first RRC connection release message is sent to the terminal upon RRC connection release. This first RRC connection release message includes a first dedicated frequency priority. The first dedicated frequency priority is used to indicate network access for the terminal; that is, the terminal can access the network according to the first dedicated frequency priority. Furthermore, the first dedicated frequency priority does not include frequency point information of the target network. If the frequency point of the target network is denoted as f(i), then the first dedicated frequency priority does not carry f(i). Therefore, the terminal can access other networks besides the target network according to other frequency points in the first dedicated frequency priority.

[0059] If the terminal is not a roaming terminal of the target network, the base station can send a second RRC connection release message to the terminal when the RRC connection is released. This second RRC connection release message includes a second dedicated frequency priority, which is used to indicate whether the terminal can access the network. The frequency information included in the second dedicated frequency priority is the frequency information of the target network. For example, the second dedicated frequency priority may only contain the frequency information of the target network. Therefore, the terminal can access the target network.

[0060] Furthermore, corresponding to step S44, if the terminal supports VoNR, the base station may not configure a dedicated priority. Alternatively, a third dedicated frequency priority can be configured, which is used to indicate the terminal's network access and includes frequency information of the target network and other networks.

[0061] In an embodiment configuring a third dedicated frequency priority, when an RRC connection is released, the base station can send a third RRC connection release message to the terminal. This third RRC connection release message includes the third dedicated frequency priority.

[0062] In this case, the terminal can select the network to access based on the list of priority third dedicated frequencies, and this disclosure does not restrict this process.

[0063] The following will refer to Figure 5 The entire process of implementing the network access method according to the embodiments of this disclosure will be described by way of example.

[0064] In step S502, the base station receives information about its own terminal capabilities sent by the terminal.

[0065] In step S504, the base station determines whether the terminal's capability information includes whether the terminal supports VoNR. If it does, step S510 is executed; otherwise, step S506 is executed.

[0066] In step S506, the base station sends a support information reporting instruction to the terminal, so that the terminal responds to the instruction and reports to the base station whether the terminal supports VoNR.

[0067] In step S508, the base station receives information on whether the terminal supports VoNR.

[0068] In step S510, the base station determines whether the terminal supports VoNR. If it does, step S522 is executed; if it does not, step S512 is executed.

[0069] In step S512, the base station determines whether the terminal is a roaming terminal of the target network to which the base station belongs. If yes, then step S514 is executed; otherwise, step S518 is executed.

[0070] In step S514, the base station configures a first dedicated frequency priority, which does not include frequency point information of the target network.

[0071] In step S516, the base station sends RRC connection release information containing the first dedicated frequency priority to the terminal so that the terminal can access the network according to the information.

[0072] In step S518, the base station configures a second dedicated frequency priority, the frequency information of which is the frequency information of the target network.

[0073] In step S520, the base station sends RRC connection release information containing a second dedicated frequency priority to the terminal so that the terminal can access the network according to the information.

[0074] In step S522, the base station either does not configure a dedicated frequency priority or configures a third dedicated frequency priority, which includes the frequency point information of the target network and the frequency point information of other networks.

[0075] In step S524, when the third dedicated frequency priority is configured in step S522, the base station sends RRC connection release information containing the third dedicated frequency priority to the terminal so that the terminal can access the network according to the information.

[0076] Based on the network access method described in this disclosure, a dedicated frequency priority is configured by considering both whether the terminal supports VoNR and whether the terminal is a roaming terminal of the target network. This solves the problem to some extent that users may not be able to receive voice services while roaming, thus ensuring a good service experience.

[0077] It should be noted that although the steps of the method in this disclosure are described in a specific order in the accompanying drawings, this does not require or imply that the steps must be performed in that specific order, or that all the steps shown must be performed to achieve the desired result. Additional or alternative steps may be omitted, multiple steps may be combined into one step, and / or a step may be broken down into multiple steps.

[0078] Furthermore, this disclosure also provides a network access device in its exemplary embodiments. This network access device is applied to a base station of a target network; that is, the network access device can be configured within the base station.

(Reference) Figure 6 The network access device 6 according to an exemplary embodiment of the present disclosure may include an information acquisition module 61, a roaming determination module 63, and a message sending module 65.

[0080] Specifically, the information acquisition module 61 can be used to acquire information sent by the terminal regarding whether the terminal supports Voice over New Radio (VoNR) service; the roaming determination module 63 can be used to determine whether the terminal is a roaming terminal of the target network if the terminal does not support VoNR; the message sending module 65 can be used to send a first RRC connection release message to the terminal when the Radio Resource Control (RRC) connection is released if the terminal is a roaming terminal of the target network. The first RRC connection release message contains a first dedicated frequency priority; wherein, the first dedicated frequency priority is used to indicate that the terminal accesses the network and the first dedicated frequency priority does not contain frequency point information of the target network.

[0081] According to an exemplary embodiment of this disclosure, the message sending module 65 may also be configured to perform the following: if the terminal is not a roaming terminal of the target network, then when the RRC connection is released, send a second RRC connection release message to the terminal, the second RRC connection release message containing a second dedicated frequency priority; wherein, the second dedicated frequency priority is used to indicate that the terminal accesses the network and the frequency point information contained in the second dedicated frequency priority is the frequency point information of the target network.

[0082] According to an exemplary embodiment of this disclosure, the roaming determination module 63 can be configured to perform: obtaining the Public Land Mobile Network (PLMN) selected by the terminal; and determining whether the terminal is a roaming terminal of the target network based on the PLMN selected by the terminal.

[0084] According to an exemplary embodiment of this disclosure, the information acquisition module 61 may also be configured to perform: if the terminal capability information does not include information on whether the terminal supports VoNR, then send a support information reporting instruction to the terminal, the support information reporting instruction being used to instruct the terminal to report information on whether the terminal supports VoNR; and receive the information reported by the terminal on whether the terminal supports VoNR.
