The present application provides a method for NSA network registration, and in order to describe the scheme of the present application more clearly, some knowledge related to NSA network registration is introduced below.
5G: is a new generation mobile communication technology, and there are two networking schemes, non-independent Networking (NSA) and independent networking (SA).
NSA networking: based on the deployment of the existing 4G infrastructure, the 5G signals are transmitted by reforming the 4G base station, so that partial services and functions are continuously dependent on the 4G network, and the method has the advantages of saving construction cost and realizing 5G quick coverage.
SA networking: the time cost required to build an independent base station to achieve large-scale 5G coverage is high, but SA has the characteristics of higher rate and lower delay. Currently, NSA networks coexist with SA networks in existing networks.
Currently, when a terminal device is switched from a resident long term evolution (Long Term Evolution, LTE) network to a 5G New Radio (NR) network, the frequency band registered by the LTE network changes due to movement of the terminal device, so that the terminal device cannot be switched to the corresponding NR network, and is always in the LTE network, and NSA network registration cannot be achieved.
Therefore, the application proposes a new NSA network registration method aiming at the technical problem that the terminal equipment cannot be switched to the corresponding NR network due to the change of the frequency band registered by the LTE network caused by the movement of the terminal equipment. According to the NSA network registration method, MRDC combinations supported by the terminal equipment are matched according to LTE frequency bands and NR frequency bands required by the network equipment, and are reported to the network equipment, when the LTE frequency bands change due to the position change of the terminal equipment, the terminal equipment can be successfully switched to an NR network in a mode of reporting the MRDC combinations, NSA network registration is achieved, and therefore the technical problem that the LTE network registration frequency bands change due to the movement of the terminal equipment, so that the terminal equipment cannot be switched to the corresponding NR network can be solved, and NSA network registration efficiency of the terminal equipment is improved.
The technical solution provided in the embodiments of the present application may be applied to various communication systems, for example, a satellite communication system, and a system in which satellite communication and cellular network are integrated, which are not listed here.
Embodiments of the present application are described below with reference to the accompanying drawings in the embodiments of the present application.
For example, referring to fig. 1, fig. 1 is a schematic diagram of an architecture of a communication system, which is also a schematic diagram of a NSA network registration scenario, provided in an embodiment of the present application.
As shown in fig. 1, the communication system mainly includes two parts, an access network and a User Equipment (UE) 101. The access network is configured to implement wireless access related functions, and mainly includes AN Access Network (AN) device 102, where the access network device includes a wireless access network (radio access network, RAN) device and other devices that access through AN air interface (such as WiFi). The interfaces between the network elements are shown in fig. 1. It should be appreciated that the network elements may also communicate using a serviced 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 AN device. A terminal device can also be called 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 (session initiation protocol, SIP) phone, a wireless local loop (wireless local loop, WLL) station, a personal digital assistant (personal digital assistant, PDA), a handheld device with wireless communication capabilities, 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 in the internet of vehicles, a terminal device in a 5G network, a terminal device in a future evolved public land mobile network (public land mobile network, PLMN), a terminal device of any form in a future network, etc.
The network device is a device for accessing the terminal device to the wireless network, and may be specifically 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, etc., as embodiments of the present application are not specifically limited.
The main steps of registering the terminal equipment in the network are as follows:
step one, the terminal equipment starts up, searches a proper cell (which can be one of a cell 1, a cell 2, a cell 3, a cell … and a cell n), initiates random access and registers an LTE network.
Step two, after the terminal equipment registers the LTE network, the network equipment issues 5G NR configuration information, and 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 registered by the LTE network is changed, so that the anchor point (LTE cell) registered by the NSA network is changed, the network equipment issues a radio resource control (Radio Resource Control, RRC) switching message, and the terminal equipment re-registers to a new LTE cell, wherein the LTE frequency band is different from the previous LTE frequency band. At this time, since the anchor point (LTE cell) of NSA network registration changes, the terminal device needs to re-register the NSA network, if the terminal device reports the MRDC capability of multiple air interfaces and dual connectivity (multi radio dual connectivity, MR-DC), it is not reported according to the combination of the required LTE frequency band and NR frequency band issued by the network side, 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 considers that there is no corresponding MRDC combination in the current LTE frequency band, the terminal device does not have NSA network communication capability, and the network side does not issue an RRC NR reconfiguration message, so that the terminal device cannot switch to the corresponding NR network, and can not be in LTE network all the time, thereby seriously affecting the network experience of the user.
Taking the communication system shown in fig. 1 as an example, based on the architecture of the communication system, the embodiment of the application further provides an NSA network registration method, where the NSA network registration method proposes that, when a terminal device registers an LTE network, a network side sends a capability query to the terminal device, queries an LTE frequency band currently supported by the terminal device and an MRDC combination formed by the terminal device and an NR frequency band, lists the LTE frequency band and the NR frequency band that the network side hopes the terminal device to report, and after the terminal device acquires the LTE frequency band and the NR frequency band, matches an 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 number of MRDC combinations supported by the terminal equipment is large, whether the index of the reported MRDC combination exceeds the maximum index value of the MRDC combination configuration table is also required to be checked, and if so, the MRDC combination to be reported is replaced with other MRDC combinations which are not necessarily reported in the MRDC combination configuration table, so that all the MRDC combinations required by the network are ensured to be reported to the network. When the terminal equipment moves to other areas, if the LTE cell has NR capability after the LTE frequency band is changed, the network side issues proper RRC NR reconfiguration information to the current LTE frequency band according to the MRDC combination reported by the terminal equipment, and adds the NR cell, so that the terminal equipment can smoothly access an NR network to realize NSA network registration, thereby improving NSA network registration efficiency.
The NSA network registration method of the present application is described below with reference to fig. 2 to 3.
Referring to fig. 2, fig. 2 is a 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 communication technology, and the method includes, but is not limited to, the following steps:
step 201: the terminal device receives a first request sent by the network device.
The terminal equipment receives a first request sent by the network equipment, wherein the first request is used for requesting to acquire first MRDC combined information, and the first MRDC combined information comprises an LTE frequency band and an NR frequency band required by the network equipment.
Correspondingly, the network device sends a first request to the terminal device, where the first request is used to request to obtain 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 a 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 the embodiment of the present application may be a device on which a processor for executing an instruction executed by a computer is mounted, and may be a smart phone, a computer, or the like, and specifically may be UE in the communication system shown in fig. 1, and is configured to execute the NSA network registration method in the embodiment of the present application, so as to solve the technical problem that the terminal device cannot be switched to a corresponding NR network due to a change in a frequency band registered by an LTE network caused by movement of the terminal device, and improve efficiency of registering the NSA network by the terminal device.
In a possible embodiment, there is further provided an implementation manner of obtaining the second MRDC combination information according to the first MRDC combination information, specifically:
after receiving a first request sent by the network device, the terminal device acquires an LTE frequency band and an NR frequency band in the first MRDC combination information, then matches and obtains one or more MRDC combinations consisting of the LTE frequency band and the NR frequency band according to the radio frequency capability of the terminal device, uses the obtained MRDC combination as second MRDC combination information, and then sends the second MRDC combination information to the network device.
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 the MRDC combinations of B1-N78, B3-N78, B20-N28, and B20-N78 according to its radio frequency capability, and reports these MRDC combinations as second MRDC combination information to the network device.
According to the embodiment of the invention, the LTE frequency band and the NR frequency band in the first MRDC combination information issued by the network equipment can be taken out, the MRDC combination is matched according to the radio frequency capability of the network equipment and reported to the network equipment, so that the network equipment issues NR configuration information according to the capability supported by the terminal equipment, and a proper NR cell is added, so that the terminal equipment can be switched to the corresponding NR frequency band, and NSA network registration is realized.
In a possible embodiment, there is further provided an implementation manner of obtaining the second MRDC combination information according to the first MRDC combination information, specifically:
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, and matches one or more MRDC combinations composed of the LTE frequency band and the NR frequency band according to the radio frequency capability of the terminal device. And under the condition that the index value of the matched MRDC combination is larger than the target threshold value, replacing the MRDC combination with the index value smaller than the target threshold value to serve 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 can be adjusted according to different application scenarios.
Illustratively, the maximum index value of the MRDC combination configuration table is 128. Since there are more MRDC combinations supported by the terminal device, it is also necessary to check whether the index of the reported MRDC combination exceeds 128, and if so, replace the MRDC combination to be reported with other MRDC combinations that are not necessarily reported and have an index value smaller than 128 in the MRDC combination configuration table, so as to ensure that all the MRDC combinations required by the network are reported to the network.
According to the embodiment of the invention, 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, and an appropriate NR cell is added, so that the terminal equipment can be switched to a corresponding NR frequency band, and NSA network registration is realized.
Step 202: the terminal device sends second MRDC combination information to the network device in response to the first request.
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 are composed 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 equipment in the embodiment of the application reports the MRDC capability, the terminal equipment is completely reported according to the frequency band combination required in the first request issued by the network equipment, when the position of the terminal equipment changes and the frequency band registered by the LTE network changes, the terminal equipment can be timely switched to the corresponding LTE frequency band, and the network equipment can add a proper NR cell according to the second MRDC combination information reported by the terminal equipment, so that the terminal equipment can be switched to the corresponding NR frequency band, and NSA network registration is realized.
According to the embodiment of the application, the technical problem that the terminal equipment cannot be switched to the corresponding NR network due to the change of the frequency band registered by the LTE network caused by the movement of the terminal equipment can be solved, and the efficiency of registering the NSA network by the terminal equipment is improved.
In a possible embodiment, a possible implementation manner of switching to the target LTE band is further provided, specifically:
the terminal equipment responds to the first request and sends second MRDC combination 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 correspondingly changed, and the terminal equipment can be switched to the target LTE frequency band.
The target LTE frequency band is an LTE frequency band in the second MRDC combination information, and has NR capability matched with the target LTE frequency band to obtain MRDC combination, so that the network equipment can send NR configuration information corresponding to the target LTE frequency band according to the capability supported by the terminal equipment, and an appropriate NR cell is added, so that the terminal equipment can be switched to a corresponding NR network, NSA network registration is realized, and NSA network registration efficiency is improved.
In a possible embodiment, a possible implementation manner of switching to the target NR frequency band is further provided, specifically:
Under the condition that the position of the terminal equipment is changed, the LTE frequency band corresponding to the terminal equipment is correspondingly changed, the terminal equipment is switched to 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 combination information reported by the terminal equipment, and an NR cell is added.
Correspondingly, the terminal equipment receives NR configuration information sent by the network equipment, wherein the target NR configuration information comprises a target NR frequency band, the target NR frequency band and the target LTE frequency band form an MRDC combination in the second MRDC combination information, and the terminal equipment can switch to the target frequency band according to the NR configuration information, so that NSA network registration is realized, and NSA network registration efficiency is improved.
In the embodiment of the invention, the terminal equipment matches the MRDC combination supported by the terminal equipment according to the LTE frequency band and the NR frequency band required by the network equipment, and reports the MRDC combination to the network equipment, when the position of the terminal equipment changes to cause the change of the LTE frequency band, the terminal equipment can be successfully switched to the NR network by reporting the MRDC combination, thereby realizing NSA network registration, solving the technical problem that the LTE network registration frequency band changes due to the movement of the terminal equipment, causing the terminal equipment to be unable to be switched to the corresponding NR network, and improving the NSA network registration efficiency of the terminal equipment.

As shown in fig. 3, the terminal device is first 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.

Then, the terminal equipment acquires an LTE frequency band and an NR frequency band required by the network equipment from the first MRDC combined information. And the terminal equipment obtains one or more MRDC combinations consisting of the LTE frequency band and the NR frequency band according to the self RF capability, wherein the MRDC combinations are MRDC capabilities supported by the terminal equipment and are MRDC combinations expected by the network equipment. Then, since there are more MRDC combinations supported by the terminal device, it is also necessary 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. If the index value of the matched MRDC combination is judged to be greater than 128, replacing the MRDC combination with an unnecessarily reported MRDC combination with the index value smaller than 128 in an MRDC combination configuration table so as to ensure that all MRDC combinations required by a 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 network equipment. If the index value of the matching MRDC combination is not greater than 128, no permutation operation is required. Under the condition that the position of the terminal equipment is changed, the LTE frequency band corresponding to the terminal equipment is 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 combination information, the target LTE frequency band has NR capability matched with the target LTE frequency band to obtain the MRDC combination, and the network equipment transmits corresponding NR configuration information to the target LTE frequency band according to the second MRDC combination information reported by the terminal equipment and adds an NR cell. Correspondingly, the terminal equipment receives NR configuration information sent by the network equipment, and switches to a target frequency band according to the NR configuration information, so that NSA network registration is realized, and NSA network registration efficiency is improved. And finally judging whether NSA network registration is successful, if so, ending registration, and if not, checking the reason of registration failure.
