In order to describe the scheme of the present application more clearly, some knowledge related to NSA network registration is introduced below.

5G: the method is a new generation mobile communication technology, and two networking schemes, namely Non-independent Networking (NSA) and independent networking (SA), exist.

NSA networking: the method is based on the existing 4G infrastructure, and the 5G signals are transmitted by transforming the 4G base station, so that part of services and functions are continuously dependent on the 4G network, and the method has the advantages of saving the construction cost and realizing the rapid 5G coverage.

SA networking: the time cost required for building an independent base station and realizing large-scale 5G coverage is high, but the SA has the characteristics of higher speed, lower time delay and the like. Currently, the NSA network and the SA network coexist in the existing network.

At present, when a terminal device is switched from a resident Long Term Evolution (LTE) network to a 5G New Radio (NR) network, a frequency band of LTE network registration changes due to movement of the terminal device, so that the terminal device cannot be switched to a corresponding NR network, and the terminal device is always in the LTE network and cannot realize NSA network registration.

Therefore, the present application provides a new NSA network registration method for solving the technical problem that the terminal device cannot be switched to the corresponding NR network due to the change of the frequency band of LTE network registration caused by the movement of the terminal device. According to the NSA network registration method, the MRDC combinations supported by the terminal equipment are matched according to the LTE frequency band and the NR frequency band required by the network equipment, and the MRDC combinations are reported to the network equipment.

The technical solution provided by the embodiments of the present application can be applied to various communication systems, for example, a satellite communication system, and a system in which satellite communication and a cellular network are converged, which are not listed here.

The embodiments of the present application will be described below with reference to the drawings.

For example, referring to fig. 1, fig. 1 is a schematic diagram of an architecture of a communication system provided in an embodiment of the present application, and is also a schematic diagram of a scenario of NSA network registration.

As shown in fig. 1, the communication system mainly includes an access network and a User Equipment (UE) 101. The access network is used for implementing functions related to wireless access, and mainly includes AN Access Network (AN) device 102, where the access network device includes a Radio Access Network (RAN) device and other devices (such as WiFi) that access through AN air interface. The interfaces between the network elements are shown in figure 1. It should be understood that the network elements may also communicate using a service interface.

A UE may also be referred to as a terminal device. The terminal device may communicate with one or more Core Networks (CNs) via the AN device. A terminal device may also be referred to as a User Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user equipment. The terminal device may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capability, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in the internet of things or vehicle network, a terminal device in a 5G network, a terminal device in a Public Land Mobile Network (PLMN) for future evolution, a terminal device in any form in a future network, and so on.

The network device is a device for accessing the terminal device to the wireless network, and may specifically be a base station. The base station may include various forms of base stations, such as: macro base stations, micro base stations (also referred to as small stations), relay stations, access points, and the like, which are not specifically limited in this embodiment of the present application.

The main steps of the terminal equipment for registering the network are as follows:

step one, the terminal device is powered on, searches for a suitable cell (which may be one of cell 1, cell 2, cell 3, …, and cell n), initiates random access, and registers with the LTE network.

Step two, after the terminal equipment registers the LTE network, the network equipment issues 5G NR configuration information, correspondingly, after the terminal equipment receives the 5G NR configuration information, the terminal equipment starts measurement and reports a 5G NR measurement report, and the network side adds a corresponding NR cell (which can be one of cell 1, cell 2, cell 3, … and cell n) according to the 5G NR measurement report, so that the terminal equipment accesses the NR cell and successfully registers the NSA network.

And step three, when the position of the terminal equipment is changed, the LTE frequency band of the LTE network registration is changed, so that an anchor point (LTE cell) of the NSA network registration is changed, the network equipment issues a Radio Resource Control (RRC) switching message, the terminal equipment is re-registered to a new LTE cell, and the LTE frequency band is also different from the prior LTE frequency band. At this time, because an anchor point (LTE cell) registered by the NSA network changes, the terminal device needs to re-register the NSA network, and if the terminal device reports a multi-radio-channel dual-connection (MR-DC) MRDC capability, the terminal device does not report the combination of the LTE frequency band and the NR frequency band that is required and delivered from the network side completely, or the MRDC combination queried by the network side exceeds the maximum reporting number of the terminal device capability, so that the MRDC combination cannot be reported to the network side, the network side may consider that there is no corresponding MRDC combination in the current LTE frequency band, the terminal device does not have the NSA network communication capability, and the network side may not issue an RRC NR reconfiguration message, so that the terminal device cannot switch to the corresponding NR network, and is always in the LTE network, so that the NSA network registration cannot be implemented, and the network experience of the user is seriously affected.

Taking the communication system shown in fig. 1 as an example, based on the architecture of the communication system, the embodiment of the present application further provides an NSA network registration method, where the NSA network registration method provides that when a terminal device registers an LTE network, the network side sends a capability query to the terminal device, queries a currently supported LTE frequency band of the terminal device and an MRDC combination formed with an NR frequency band, lists the LTE frequency band and the NR frequency band that the network side desires to report to the terminal device, and after the terminal device acquires the LTE frequency band and the NR frequency band, matches a MRDC combination supported by the current terminal device according to its Radio Frequency (RF) capability, and reports the MRDC combinations to the network side. Because the MRDC combinations supported by the terminal device are many, it is also necessary to check whether the index of the reported MRDC combination exceeds the maximum index value of the MRDC combination configuration table, and if so, the MRDC combination to be reported is replaced with other unnecessary MRDC combinations reported in the MRDC combination configuration table, so as to ensure that all MRDC combinations required by the network are reported to the network. When the terminal device moves to other areas, after the LTE frequency band changes, if the LTE cell has NR capability, the network side issues appropriate RRC NR reconfiguration information to the current LTE frequency band according to the MRDC combination reported by the terminal device, and adds the NR cell, so that the terminal device can smoothly access the NR network, thereby realizing NSA network registration and improving the NSA network registration efficiency.

The NSA network registration method of the present application is explained below with reference to fig. 2 to 3.

Referring to fig. 2, fig. 2 is a schematic flow chart of an NSA network registration method according to an embodiment of the present application, where the NSA network registration method relates to the field of communications technologies, and the method includes, but is not limited to, the following steps:

step 201: the terminal equipment receives a first request sent by the network equipment.

The terminal device receives a first request sent by the network device, where the first request is used to request to acquire first MRDC combined information, and the first MRDC combined information includes an LTE frequency band and an NR frequency band required by the network device.

Correspondingly, the network device sends a first request to the terminal device, where the first request is used to request to acquire first MRDC combined information, where the first MRDC combined information includes an LTE frequency band and an NR frequency band required by the network device, that is, the network device sends the first request to the terminal device, where the first request is used to request the LTE frequency band and the NR frequency band required by the network device.

The terminal device in this embodiment of the present application is a device, which is equipped with a processor capable of executing a computer execution instruction, and may be a smart phone, a computer, or the like, and specifically may be the UE in the communication system shown in fig. 1, and is configured to execute the NSA network registration method in this embodiment of the present application, so as to solve a technical problem that the terminal device cannot be switched to a corresponding NR network due to a change in a frequency band of LTE network registration caused by movement of the terminal device, and improve efficiency of the terminal device in registering the NSA network.

In a possible embodiment, an implementation manner of obtaining the second MRDC combination information according to the first MRDC combination information is further provided, which specifically includes:

after receiving a first request sent by the network device, the terminal device obtains an LTE frequency band and an NR frequency band in the first MRDC combination information, then matches to obtain one or more MRDC combinations composed of the LTE frequency band and the NR frequency band according to its own radio frequency capability, uses the obtained MRDC combinations as second MRDC combination information, and then sends the second MRDC combination information to the network device.

Illustratively, the LTE frequency band numbers in the first MRDC combination information are B1, B3, and B20, the NR frequency band numbers in the first MRDC combination information are N28, and N27, and the terminal device matches MRDC combinations of B1-N78, B3-N78, B20-N28, and B20-N78 according to its radio frequency capability, and reports the MRDC combinations as second MRDC combination information to the network device.

According to the embodiment of the application, the LTE frequency band and the NR frequency band in the first MRDC combined information issued by the network equipment can be taken out, the MRDC combined information is reported to the network equipment according to the matching of the radio frequency capacity of the network equipment, the network equipment issues the NR configuration information according to the capacity supported by the terminal equipment, a proper NR cell is added, the terminal equipment can be switched to the corresponding NR frequency band, and NSA network registration is realized.

after receiving a first request sent by the network device, the terminal device obtains the LTE frequency band and the NR frequency band in the first MRDC combination information, and matches to obtain one or more MRDC combinations composed of the LTE frequency band and the NR frequency band according to its radio frequency capability. And under the condition that the index value of the MRDC combination obtained by matching is greater than the target threshold, replacing the MRDC combination with the index value smaller than the target threshold to be used as second MRDC combination information, and then sending the second MRDC combination information to the network equipment. The target threshold is not a fixed value, and may be adjusted according to different application scenarios.

Illustratively, the maximum index value of the MRDC combined configuration table is 128. Because the MRDC combinations supported by the terminal device are many, it is also necessary to check whether the index of the reported MRDC combination exceeds 128, and if so, the MRDC combination to be reported is replaced with other unnecessary MRDC combinations reported in the MRDC combination configuration table, whose index values are less than 128, to ensure that all MRDC combinations required by the network are reported to the network.

By the embodiment of the application, the MRDC capability supported by the terminal equipment can be reported to the network equipment, so that the network equipment can issue NR configuration information according to the capability supported by the terminal equipment, a proper NR cell is added, the terminal equipment can be switched to a corresponding NR frequency band, and NSA network registration is realized.

Step 202: the terminal device transmits second MRDC combination information to the network device in response to the first request.

And the terminal device responds to the first request and sends second MRDC combination information to the network device, wherein the second MRDC combination information comprises one or more MRDC combinations supported by the terminal device capability, and the MRDC combinations consist of LTE frequency bands and NR frequency bands required by the network device. Correspondingly, the network device receives the second MRDC combination information sent by the terminal device.

When the terminal device reports the MRDC capability, the MRDC capability is completely reported according to the frequency band combination required in the first request issued by the network device, and when the position of the terminal device changes and the frequency band of the LTE network registration changes, the terminal device can switch to the corresponding LTE frequency band in time, and the network device can add a suitable NR cell according to the second MRDC combination information reported by the terminal device, so that the terminal device can switch to the corresponding NR frequency band, and thereby implementing NSA network registration.

By the embodiment of the application, the technical problem that the terminal equipment cannot be switched to a corresponding NR (noise-and-noise) network due to the fact that the frequency band of LTE (Long term evolution) network registration changes caused by the movement of the terminal equipment can be solved, and the efficiency of the terminal equipment for registering NSA (network spanning tree) network is improved.

In a possible embodiment, a possible implementation manner for switching to a target LTE frequency band is further provided, which specifically is as follows:

and the terminal equipment responds to the first request and sends second MRDC combined information to the network equipment, and under the condition that the position of the terminal equipment is changed, the LTE frequency band corresponding to the terminal equipment is also correspondingly changed, and the terminal equipment can be switched to the target LTE frequency band.

The target LTE frequency band is the LTE frequency band in the second MRDC combined information, and the target LTE frequency band has NR capability matched with the target LTE frequency band to obtain an MRDC combination, so that the network device can issue NR configuration information corresponding to the target LTE frequency band according to the capability supported by the terminal device, add an appropriate NR cell, realize that the terminal device can switch to a corresponding NR network, realize NSA network registration, and improve NSA network registration efficiency.

In a possible embodiment, a possible implementation manner of switching to a target NR frequency band is further provided, which specifically includes:

and under the condition that the position of the terminal equipment is changed, the LTE frequency band corresponding to the terminal equipment is also correspondingly changed, the terminal equipment is switched to the target LTE frequency band, the network equipment issues corresponding NR configuration information to the target LTE frequency band according to the second MRDC combined information reported by the terminal equipment, and an NR cell is added.

Correspondingly, the terminal device receives NR configuration information sent by the network device, where the target NR configuration information includes a target NR frequency band, and the target NR frequency band and the target LTE frequency band constitute an MRDC combination in the second MRDC combination information, and the terminal device may switch to the target frequency band according to the NR configuration information, thereby implementing NSA network registration and improving NSA network registration efficiency.

In the embodiment of the application, the terminal device matches the MRDC combinations supported by the terminal device according to the LTE frequency band and the NR frequency band required by the network device, and reports the MRDC combinations to the network device, and when the LTE frequency band changes due to a change in the position of the terminal device, the terminal device can successfully switch to the NR network by reporting the MRDC combinations, so that NSA network registration is realized, thereby solving the technical problem that the terminal device cannot switch to the corresponding NR network due to a change in the frequency band registered by the LTE network caused by movement of the terminal device, and improving the efficiency of the terminal device in registering the NSA network.

Referring to fig. 3, fig. 3 is a flowchart illustrating another NSA network registration method according to an embodiment of the present application, which can also be understood as a modification or a supplement of the flowchart of the NSA network registration method in fig. 2.

As shown in fig. 3, first, the terminal device is powered on, searches for a suitable cell (which may be one of cell 1, cell 2, cell 3, …, and cell n shown in fig. 1), initiates random access, and registers with the LTE network. At this time, the network device issues a first request, where the first request is used to request to acquire first MRDC combined information, where the first MRDC combined information includes an LTE frequency band and an NR frequency band required by the network device, and correspondingly, the terminal device receives the first request issued by the network device. Then, the terminal device obtains the LTE frequency band and the NR frequency band required by the network device from the first MRDC combined information. And the terminal device obtains one or more MRDC combinations composed of the LTE frequency band and the NR frequency band according to its RF capability, and these MRDC combinations are MRDC capabilities supported by the terminal device and are MRDC combinations desired by the network device. Next, since the MRDC combinations supported by the terminal device are many, it is further required to check whether the reported index of the MRDC combination exceeds the maximum index value of the MRDC combination configuration table, for example, determine whether the index value of the matched MRDC combination is greater than the maximum index value 128 of the MRDC combination configuration table. And if the index value of the matched MRDC combination is judged to be larger than 128, replacing the MRDC combination with the unnecessarily reported MRDC combination with the index value smaller than 128 in the MRDC combination configuration table to ensure that all MRDC combinations required by the network are reported to the network, taking the MRDC combination configuration table obtained after replacement as second MRDC combination information, and then sending the second MRDC combination information to the network equipment. If the index value of the matched MRDC combination is judged not to be larger than 128, the replacement operation is not needed. And under the condition that the position of the terminal equipment is changed, the LTE frequency band corresponding to the terminal equipment is also correspondingly changed, the terminal equipment can be switched to a target LTE frequency band, wherein the target LTE frequency band is the LTE frequency band in the second MRDC combined information, the target LTE frequency band has the NR capability of obtaining the MRDC combination by matching with the target LTE frequency band, and the network equipment issues corresponding NR configuration information to the target LTE frequency band according to the second MRDC combined information reported by the terminal equipment and adds an NR cell. Correspondingly, the terminal device receives the NR configuration information sent by the network device, and switches to the target frequency band according to the NR configuration information, thereby realizing NSA network registration and improving NSA network registration efficiency. And finally, judging whether NSA network registration is successful or not, if so, finishing the registration, and if not, checking the reason of the registration failure.
