Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

One possible implementation of the 5G terminal determination method may be that, based on Service Profile Identifier (SPID) pushing, an operator configures a corresponding SPID Identifier for a 5G package user in a Home Subscriber Server (HSS), an eNB configures the anchor frequency band priority level for the SPID to be the highest, and a terminal device (user equipment, UE) switches to an anchor cell through the frequency point priority level.

Another possible implementation of the 5G terminal determining method may be based on UE capability identification and push, and determine whether the terminal is a 5G terminal by identifying whether a New Radio (NR) frequency band is supported in the terminal capability reported by the UE, issue measurement control, measure a highest priority anchor point, and switch the UE to an anchor point cell through the priority of the frequency point.

However, in the method for identifying the 5G terminal based on SPID push, the 5G package users do not all hold the 5G terminal, which results in that the non-5G terminal is reselected to the anchor cell in the anchor preferred flow, because the non-5G terminal does not support the 5G frequency band, the non-5G terminal cannot reside in the anchor cell, which results in the non-5G terminal having ping-pong handover to occupy the cell, and thus the method has an error in judgment of the 5G terminal.

In the method for identifying, pushing and identifying the 5G terminal based on the UE capability, whether the terminal is the 5G terminal is judged by identifying whether the terminal capability reported by the UE supports the NR frequency band, however, part of the terminals do not turn on a 5G network function switch in the system software setting actually, and can preferentially reside in the anchor cell through the anchor frequency point. Therefore, the load of the anchor point cell is increased, for part of anchor point cells with high load, the use of a terminal user which really starts the 5G network function is influenced, and although the method can correctly judge that the terminal is a 5G terminal, the method cannot accurately judge whether the terminal software function really supports 5G.

Under the condition of co-establishment and sharing based on a 5G network among current operators, after the optimization of a shared frequency point is started, the terminal capacity does not need to be judged, namely, the whole number of terminals are all optimized to a shared cell, after the terminal resides in the shared anchor point cell, the terminal capacity is identified, and a non-anchor point optimization switching is issued to a non-anchor point cell for a non-5G terminal, so that the non-5G terminal is subjected to ping-pong switching to occupy cell network resources, and the use feeling of a user on the 5G network is influenced.

Therefore, an embodiment of the present application provides a 5G terminal determining method based on NSA, including: collecting the content of Tracking Area Update (TAU) signaling of a core network control plane interface (S1-mobility management entity, S1-MME) in NSA; according to the content of the TAU signaling, identifying a plurality of first 5G terminals accessed into the core network, and determining whether the plurality of first 5G terminals start the 5G network function or not; screening one or more second 5G terminals of which the network capability information indicates to start a 5G network function from a plurality of first 5G terminals; sending indication information to a Mobility Management Entity (MME), the indication information indicating that a service profile identifier SPID of one or more second 5G terminals is set as a first identifier; and sending the set SPIDs of the one or more second 5G terminals to the 5G base station, wherein the SPIDs are used for the 5G base station to configure the Long Term Evolution (LTE) frequency point priority for the SPIDs of the one or more second 5G terminals, and setting the anchor point frequency point as the highest priority.

In a possible implementation manner, when a 5G terminal user initiates a TAU in a 4G Network, the reported terminal Network Capability (MS Network Capability) can accurately distinguish whether the user terminal supports the 5G Network by identifying the Dual connectivity of E-UTRA with NR Capability (DCNR) of the terminal.

Fig. 1 is a schematic diagram of an NSA 3X network architecture according to an embodiment of the present disclosure.

As shown in fig. 1, in the current NSA networking architecture, each mainstream operator uses (option 3X) 3X networking architecture, a 4G base station eNB is used as an anchor cell, a 5G base station gNB is used as an auxiliary node, when a UE moves into coverage of a 5G network, a wireless base station side triggers a 5G terminal to switch to the anchor cell, the gNB is added as an auxiliary node, a user plane data flow is switched to the gNB, and a signaling plane data flow is still controlled by the eNB. When the UE initiates a tracking area update, it needs to report a terminal network capability and an International Mobile Equipment Identity (IMEI), where the IMEI may identify whether the terminal is a 5G terminal, when the SIM card of the user is used in the first card slot, the terminal network capability includes a DCNR bit indicating whether the terminal supports a 5G network, and when the SIM card of the user is used in the second card slot, the terminal network capability does not include the DCNR bit.

For example, the SPID of a specific user who opens a 5G network function in the 5G terminal device is updated to 1. It is understood that the first identifier may include other contents according to an actual scenario, which is not limited in the embodiment of the present application.
