Technical Field

Background
The New air interface (NR) networking of the fifth generation mobile communication system (5G) includes independent networking (SA, stand Alone) and Non-independent networking (NSA, non Stand Alone). For a terminal supporting SA and NSA simultaneously, after the terminal is accessed in a 4G network coverage area, the terminal works in a 4G network mode; when the terminal moves to the overlapping coverage area of the 5G network and the 4G network, if the overlapping coverage network also supports SA and NSA, the network will face two options of configuring dual connectivity or switching to 5G SA.
The terminal does not necessarily support adaptive switching between the SA and NSA modes, i.e. switching from NSA to SA, although it supports SA and NSA. If the terminal does not support switching from NSA to SA, the 4G base station will cause the terminal to fail to switch when deciding to switch to SA and executing the switching. In addition, if the 4G base station decides to switch to the SA, the 5G core network may refuse to switch because the SA has not subscribed during the switching process, resulting in failure of switching the 4G network to the 5G network. The 4G base station turns to configure NSA dual connectivity. If the terminal frequently enters the coverage area of the 5G network, the failure will also frequently occur, which affects the user experience.

Detailed Description
The invention will be described in further detail with reference to the accompanying drawings and specific examples.
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. Wherein NSA refers to the independent deployment of control plane by 4G network, the co-deployment of user plane by 5G network and 4G network or the independent deployment of user plane by 5G network. SA refers to the independent deployment of control plane and user plane by 5G network. In the SA mode, an end-to-end network of 5G needs to be deployed independently, and a base station and a core network of the 5G network are newly built, so that the SA mode can work independently of the 4G network. The non-independent networking mode can rely on the existing 4G network, thereby meeting the prior requirements of partial operators on the 5G network.
For a terminal supporting SA and NSA simultaneously, after the terminal is accessed in a 4G network coverage area, the terminal works in a 4G network mode; when the terminal moves to the overlapping coverage area of the 5G network and the 4G network, if the overlapping coverage network also supports SA and NSA, the network will face two options of configuring dual connectivity or switching to 5G SA.
Assuming that when deciding to switch to SA priority, the base station of the 4G network switches the terminal to access the 5G network preferentially, the base station of the 4G network sends a switching request of the terminal to a mobility management entity (MME, mobility Management Entity) 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 a SA subscription (e.g. a global subscriber identity (USIM, universal Subscriber Identity Module) card inserted by the terminal has not subscribed on SA), and if there is a SA subscription, the switching process will continue. If there is no SA subscription, the 5G core network will reject the handover.
Therefore, the 4G base station judges that the 5G network is switched in, and the 5G core network refuses to switch due to no SA subscription in the switching process, so that the 4G network fails to switch to the 5G network, and the 4G base station is converted into the NSA dual-connection configuration. 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 the failure will also occur in ping-pong, which affects the user experience. Based on this, the following embodiments of the present invention are presented.
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 used interchangeably herein. The term "and/or" is herein merely an association relationship describing an associated object, meaning that there may be three relationships, e.g., a and/or B, may represent: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are 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 invention; as shown in fig. 1, the method includes:
step 101: the method comprises the steps that a first access network device obtains capability information of a terminal; the capability information characterizes 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 indicates the terminal to disable SA capability according to the capability information when the access is switched to the second network and the access is failed.
The access network device in the embodiment of the invention refers to a base station in a first network, and particularly refers to a base station of a 4G network. The first network may be a 4G network, and the second network may be a 5G network.
In this embodiment, the capability information of the terminal may include whether the terminal supports SA capability, and in the case that the terminal supports SA capability, the capability information of the terminal further includes whether switching between NSA capability and SA capability is supported. In another embodiment, the capability information of the terminal further includes SA capability priority or NSA capability priority; the SA capability preferentially indicates that when the dual connection based on the first network and the second network is judged to be established or the access to the second network is switched, the access to the second network is preferentially switched; NSA capability prioritizes establishing dual connectivity based on the first network and the second network when deciding to establish dual connectivity based on the first network and the second network or to hand off access to the second network.
As an implementation manner, the first access network device may obtain the capability information of the terminal during the terminal power-on attachment process, that is, the terminal sends the capability information to the first access network device during the terminal power-on attachment process to access the 4G network. As an example, the first access network device may obtain capability information of the terminal through non-access stratum (NAS, non Access Stratum) signaling. As another example, the first access network device may obtain 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 indicating bit can be added in a specific field in any signaling, and the value of the bit indicating bit indicates whether the terminal supports switching between NSA capability and SA capability. Specifically, as shown in the following code, the handover-SA-NSA-Capability field is set to support, which indicates that switching between NSA Capability and SA Capability is supported, and the refer-Mode field is set to SA, which indicates that SA Capability is prioritized.
In this embodiment, after the terminal accesses the first network, the terminal moves to a coverage area of the second network, and before the terminal switches to access to the second network according to the capability information, the method further includes: and establishing dual connection based on the first network and the second network or switching access to the second network according to the capability information.
In an optional embodiment of the invention, the determining to establish a dual connection based on the first network and the second network or to switch access to the second network according to the capability information includes: when the capability information indicates that the terminal supports switching of NSA capability and SA capability, and SA capability is prioritized over NSA capability, judging that switching is prioritized to access to the second network; when the capability information indicates that the terminal supports switching of NSA capability and SA capability and NSA capability is higher than SA capability, judging that dual connection based on the first network and the second network is established preferentially; and when the capability information does not indicate that the terminal supports switching of NSA capability and 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 switching between NSA capability and SA capability is supported and SA capability is prioritized, the first access network device determines to access to the second network by priority switching. 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 access to the second network. For example, a base station of the 4G network communicates with a second core network device of the 5G network through a first core network device of the 4G network to switch access to the 5G network. If the capability information of the terminal indicates that switching of NSA capability and SA capability is supported and NSA capability is priority, the first access network equipment judges that dual connection based on the first network and the second network is established preferentially. Or if the capability information of the terminal does not indicate that the terminal supports switching of NSA capability and SA capability, the first access network equipment judges that dual connection based on the first network and the second network is preferentially established. In practical application, the first access network device communicates with a first core network device of the first network and a second core network device of the second network respectively, so as to establish dual connection based on the first network and the second network respectively. 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 connections based on the 4G network and the 5G network, respectively.
The first core network device and the second core network device include, but are not limited to, a core network device, and in practical application, information interaction between a plurality of core network devices may be performed, so as to implement a second network for switching access, or implement establishment of dual connection based on the first network and the second network.
In an alternative embodiment of the present invention, the failure of the handover access to the second network includes: the first access network equipment obtains switching failure information of first core network equipment of the first network; the handover failure information includes a handover failure cause because the SA capability of the terminal is not subscribed to the second network; and the handover failure information is sent to the first core network device by the second core network device of the second network.
As an example, the first access network device sends a handover request to a second core network device of the 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 checks the SA capability of the terminal, specifically checks whether the terminal signs up for the SA capability. If the verification result is that the user 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 switching failure reason that the SA capability of the terminal is not signed; and the first core network equipment of the first network sends the handover failure information to the first access network equipment. If the checking result is subscription, the second core network device of the second network sends switching acceptance information to the first core network device of the first network to indicate that the second network allows the terminal to switch access.
In an optional embodiment of the invention, the instructing the terminal to disable 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 to establish dual connectivity based on the first network and the second network on the one hand, and on the other hand, the reconfiguration information includes indication information for indicating 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: the first access network device sends reconfiguration information to the terminal through radio resource control (RRC, radio Resource Control) 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 RRC connection reconfiguration signaling, and may specifically be indicated by a code that indicates that the SA capability is disabled through indication information carried in the RRC connection reconfiguration signaling.
In an alternative 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 the second access network equipment; 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 device and the second access network device in the embodiment of the invention are both base stations in the 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 can serve as a source base station, and the second access network device can serve as a target base station. And when the first access network equipment determines that the SA capability of the terminal is not signed on the second network, the first access network equipment sends a notification message to the second access network equipment so as to be convenient for the first access network equipment to synchronize the information of the SA capability of the disabled terminal to the second access network equipment when the terminal is switched from the first access network equipment to the second access network equipment, and the second access network equipment serving as a target base station can conveniently send 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, etc. when issuing the measurement parameters to the terminal.
In this embodiment, the capability of enabling or disabling SA by the terminal may be embodied by a related parameter reported by the terminal. For example, if the terminal disables the SA capability, the measurement parameter reported by the terminal does not include the related information of the 5G cell; if the terminal starts the SA capability, the measurement parameters reported by the terminal can 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 area of the second network after accessing the first network, after the terminal is refused to switch access to the second network for the first time, the SA capability of the disabled terminal is indicated by the access network equipment (such as the base station), so that the situation that the terminal is frequently switched to access to the second network and fails to switch is avoided, and the user experience is greatly improved.

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 to establish double connection based on the 4G network and the 5G network or switch access to the 5G network according to the received capability information.
Step 203: when the switching access to the 5G network is judged, the base station of the 4G network switches access to the 5G network.
Step 204: a base station of the 4G network receives the switching failure information and sends reconfiguration information to the terminal; the handover failure information includes a handover failure cause because the SA capability of the terminal is not subscribed to the second network; the reconfiguration information includes indication information for indicating that the SA capability is disabled.
