Background
New Radio (NR) networking of a fifth generation mobile communication system (5G) includes independent networking (SA, Stand Alone) and dependent networking (NSA, Non Stand Alone). For a terminal supporting SA and NSA simultaneously, the terminal works in a 4G network mode after being accessed in a 4G network coverage area; when the terminal moves to the overlapping coverage area of the 5G network and the 4G network, if the overlapping coverage area network also supports SA and NSA, the network will face two options of configuring dual connectivity or switching to 5G SA.
Although the terminal supports SA and NSA, it does not necessarily support adaptive switching between the two modes, namely, switching from NSA to SA is not supported. If the terminal does not support switching from NSA to SA, when the 4G base station judges to switch to SA and executes switching, the terminal switching fails. In addition, if the 4G base station decides to switch to the SA, the 5G core network may refuse to switch because the SA is not subscribed during the switching process, resulting in a failure of switching the 4G network to the 5G network. The 4G base station is switched to configure NSA dual connectivity. If the terminal frequently enters the coverage area of the 5G network, such failure will also occur frequently, affecting the user experience.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The technical scheme of the embodiment of the invention is applied to a communication system and comprises a fourth generation mobile communication technology (4G) network and a fifth generation mobile communication technology (5G) network. The voice schemes for 5G networks include SA and NSA, respectively. The NSA refers to a control plane independently deployed by a 4G network, and a user plane jointly deployed by a 5G network and the 4G network or a user plane independently deployed by the 5G network. SA refers to a 5G network independently deploying a control plane and a user plane. The SA mode requires independent deployment of a 5G end-to-end network, and newly establishes a base station and a core network of the 5G network, so the SA mode can work without depending on a 4G network. The non-independent networking mode can depend on the existing 4G network, so that the requirement of part of operators on the 5G network is met.
For a terminal supporting SA and NSA simultaneously, the terminal works in a 4G network mode after being accessed in a 4G network coverage area; when the terminal moves to the overlapping coverage area of the 5G network and the 4G network, if the overlapping coverage area network also supports SA and NSA, the network will face two options of configuring dual connectivity or switching to 5G SA.
Assuming that when the switching to the SA priority is determined, the base station of the 4G network preferentially switches the terminal to access the 5G network, the base station of the 4G network sends a switching request of the terminal to a Mobility Management Entity (MME) of the 4G network, the MME further forwards the switching request to the 5G core network, the 5G core network checks whether the terminal has an SA subscription (for example, a Universal Subscriber Identity Module (USIM) card inserted by the terminal does not sign on the SA), and if the SA subscription exists, the switching process is continuously performed. If there is no SA subscription, the 5G core network will reject the handover.
Therefore, the 4G base station decides to switch to access the 5G network, and it is possible that the 5G core network rejects the switching due to no SA subscription in the switching process, so that the switching from the 4G network to the 5G network fails, and the 4G base station switches to configure the NSA dual connection. If the terminal frequently enters the 5G coverage area, the 4G base station attempts to switch to the 5G network based on the capability of the terminal to support NSA and SA, and this failure will also occur ping-pong, which affects the user experience. Based on this, the following examples of the present invention are proposed.
Optionally, the communication network in the embodiment of the present invention includes at least a 4G network and a 5G network.
It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and/or" herein is merely an association describing an associated object, meaning that three 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 embodiment of the invention provides a data processing method. FIG. 1 is a flow chart of a data processing method according to an embodiment of the present invention; as shown in fig. 1, the method includes:
step 101: the first access network equipment acquires the capability information of the terminal; the capability information represents whether the terminal supports switching of NSA capability and SA capability.
Step 102: and if the terminal moves from the first network to the coverage area of the second network, the first access network equipment switches to access the second network according to the capability information and indicates the terminal to disable the SA capability when the switching to access the second network fails.
The access network device in the embodiment of the present invention refers to a base station in a first network, and specifically refers to a base station of a 4G network. The first network may specifically be a 4G network, and the second network may specifically be a 5G network.
In this embodiment, the capability information of the terminal may include whether the terminal supports an SA capability, and in a case that the terminal supports the SA capability, the capability information of the terminal further includes whether switching between an NSA capability and the SA capability is supported. In another embodiment, the capability information of the terminal further includes SA capability priority or NSA capability priority; wherein the SA capability priority indicates that when judging to establish dual connection based on the first network and the second network or switch to access to the second network, the second network is switched to access preferentially; the NSA capability priority indicates that the dual connection based on the first network and the second network is preferentially established when the dual connection based on the first network and the second network is determined to be established or switched to be accessed to the second network.
As an implementation manner, the first access network device may obtain the capability information of the terminal in a terminal startup attachment process, that is, in a terminal startup attachment process to access a 4G network, the terminal sends the capability information to the first access network device. As an example, the first Access network device may obtain the capability information of the terminal through Non Access Stratum (NAS) signaling. As another example, the first access network device may obtain the capability information of the terminal through any signaling during the process of accessing the first network by the terminal.
In practical application, taking the capability information of the terminal obtained through any signaling as an example, a bit indication bit may be added to a specific field in any signaling, and a value of the bit indication bit indicates whether the terminal supports switching between the NSA capability and the SA capability. Specifically, as shown in the following code, the handover-SA-NSA-Capability field is set to support, indicating that switching between the NSA Capability and the SA Capability is supported, and the prefer-Mode field is set to SA, indicating that the SA Capability is prioritized.
In this embodiment, after the terminal accesses the first network, the terminal moves to a coverage area of a second network, and before the terminal switches to access the second network according to the capability information, the method further includes: and judging whether to establish dual connection based on the first network and the second network or switch access to the second network according to the capability information.
In an optional embodiment of the present invention, the determining to establish a dual connection based on the first network and the second network or to handover access to the second network according to the capability information includes: when the capability information indicates that the terminal supports switching between the NSA capability and the SA capability is prior to the NSA capability, judging that the terminal is switched to access the second network preferentially; when the capability information indicates that the terminal supports switching between the NSA capability and the SA capability and the NSA capability is prior to the SA capability, judging that the dual connection based on the first network and the second network is preferentially established; and when the capability information does not indicate that the terminal supports the switching of the NSA capability and the SA capability, judging that the dual connection based on the first network and the second network is preferentially established.
In this embodiment, if the capability information of the terminal indicates that the switching between the NSA capability and the SA capability is supported and the SA capability is prioritized, the first access network device determines to prioritize the switching access to the second network. In practical application, the first access network device communicates with the second core network device of the second network through the first core network device of the first network, so as to switch to access to the second network. For example, a base station of a 4G network communicates with a second core network device of a 5G network through a first core network device of the 4G network to handover access to the 5G network. And if the capability information of the terminal indicates that the switching of the NSA capability and the SA capability is supported and the NSA capability is prior, the first access network equipment judges that the dual connection based on the first network and the second network is preferentially established. Or, if the capability information of the terminal does not indicate that the terminal supports the switching of the NSA capability and the SA capability, the first access network device determines to preferentially establish the dual connectivity based on the first network and the second network. In practical application, the first access network device communicates with a first core network device of a first network and a second core network device of a second network, so as to establish dual connectivity based on the first network and the second network. For example, a base station of the 4G network communicates with a first core network device of the 4G network and a second core network device of the 5G network, respectively, to establish dual connectivity based on the 4G network and the 5G network, respectively.
In practical application, the information interaction of a plurality of core network devices may be performed, so as to implement a second network for switching access, or to implement establishment of dual connectivity based on a first network and a second network.
In an optional embodiment of the present invention, the failure of the handover access to the second network includes: the first access network equipment obtains the switching failure information of first core network equipment of the first network; the switching failure information comprises that the switching failure reason is that the SA capability of the terminal is not signed by the second network; and the switching failure information is sent to the first core network equipment by the second core network equipment of the second network.
As an example, a first access network device sends a handover request to a second core network device of a second network through a first core network device of the first network, where the handover request includes SA capability related information of the terminal; and the second core network equipment of the first network verifies the SA capability of the terminal, specifically, whether the terminal signs the SA capability is verified. If the verification result is that the terminal is not signed, the second core network equipment of the second network sends switching failure information to the first core network equipment of the first network, wherein the switching failure information carries a switching failure reason because the SA capability of the terminal is not signed; and the first core network equipment of the first network sends the switching failure information to the first access network equipment. And if the verification result is subscription, the second core network equipment of the second network sends switching acceptance information to the first core network equipment of the first network to indicate that the second network allows the terminal to be switched and accessed.
In an optional embodiment of the present invention, the instructing the terminal to disable an independent networking SA capability includes: the first access network equipment sends reconfiguration information to the terminal; the reconfiguration information includes indication information for indicating that the SA capability is disabled.
In this embodiment, the first access network device sends reconfiguration information to the terminal, where the reconfiguration information is used to configure and establish dual connectivity based on the first network and the second network, and on the other hand, the reconfiguration information includes indication information used to indicate that the SA capability is disabled, so that the terminal disables the SA capability after receiving the indication information.
Optionally, the sending, by the first access network device, reconfiguration information to the terminal includes: and the first access network equipment sends reconfiguration information to the terminal through Radio Resource Control (RRC) signaling.
As an example, the first access network device may send, to the terminal, indication information for indicating that the SA capability is disabled through an RRC connection reconfiguration signaling, and specifically, as shown in the following code, the indication information carried in the RRC connection reconfiguration signaling indicates that the SA capability is disabled.
In an optional embodiment of the invention, the method further comprises: the first access network equipment sends a notification message representing the SA capability of the disabled terminal to second access network equipment; wherein the notification message is synchronized to the second access network device when the terminal is switched from accessing the first access network device to accessing the second access network device; the first access network device and the second access network device are both access network devices in the first network.
The first access network equipment and the second access network equipment in the embodiment of the invention are both base stations in a 4G network; the first access network device and the second access network device are different base stations in a 4G network. When the terminal is to be switched from the first access network device to the second access network device, the first access network device may serve as the source base station, and the second access network device may serve as the target base station. When the first access network device determines that the SA capability of the terminal is not under the second network subscription, the first access network device sends a notification message to the second access network device, so that when the terminal is to be switched from the first access network device to the second access network device, the first access network device synchronizes the information of the SA capability of the disabled terminal to the second access network device, and the second access network device serving as the target base station can issue information, such as measurement parameters and the like, to the terminal based on the information of the SA capability of the disabled terminal. As an example, if the source base station sends a notification message to the target base station that the SA capability of the terminal has been disabled, the target base station does not include the measurement parameters for the 5G cell and the like when issuing the measurement parameters to the terminal.
In this embodiment, the SA enabling or disabling capability of the terminal may be embodied by the related parameters reported by the terminal. For example, if the terminal disables the SA capability, the measurement parameters reported by the terminal do not include the relevant information of the 5G cell; if the terminal enables the SA capability, the measurement parameters reported by the terminal may include related information of the 5G cell, and the like.
By adopting the technical scheme of the embodiment of the invention, when the terminal moves to the coverage range of the second network after accessing the first network, after the terminal is switched to access the second network for the first time and is refused, the access network equipment (such as a base station) indicates to disable the SA capability of the terminal, thereby avoiding the subsequent frequent switching of the terminal to access the second network and the failure of switching, and greatly improving the user experience.

step 201: the terminal reports the capability information when accessing the 4G network, wherein the capability information can include whether switching between the NSA capability and the SA capability is supported; when the capability information includes the capability information supporting the switching of the NSA capability and the SA capability, the capability information may further include NSA capability priority or SA capability priority.
Step 202: when the terminal moves from the 4G network to the coverage area of the 5G network, the base station of the 4G network judges whether to establish dual connection based on the 4G network and the 5G network or switch to access to the 5G network according to the received capability information.
Step 203: and when the base station of the 4G network is switched to be accessed to the 5G network, switching the base station of the 4G network to be accessed to the 5G network.
Step 204: the base station of the 4G network receives the switching failure information and sends reconfiguration information to the terminal; the switching failure information comprises that the switching failure reason is that the SA capability of the terminal is not signed by the second network; the reconfiguration information includes indication information for indicating that the SA capability is disabled.
