Description

Non-independent networking residence method, equipment and computer readable storage medium

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and apparatus for residence of a non-independent network, and a computer readable storage medium.

Background

In the prior art, in the early stage of 5G network implementation, in order to protect the investment of the existing 4G network and hope to rapidly deploy the 5G network, operators mostly start to adopt an NSA (Non-standby independent networking) scheme. The 4G core network (EPC) is shared between such networking 4G base stations (enbs) and 5G base stations (gnbs), wherein an eNB is the master station and a gNB is the slave station, with control plane signaling going through the 4G path to the EPC. The networking has the advantage that a 5G core network (NGCN) does not need to be newly added, and operators can rapidly deploy 5G by utilizing the existing 4G network infrastructure to preempt coverage and hot spots.

However, as can be seen from the NSA scheme described above, the 5G base station is a module that depends on the 4G core network and the 4G base station, the terminal needs to support the 4G and 5G, and takes a dual standby mode. The terminal must register to a certain cell of the 4G network, then searches for the 5G cell according to the information of the 5G cell configured in the cell system changing message, and after the 5G cell is searched, the terminal can reside in the 5G network only after finishing the necessary access flow, and the corresponding service is developed through the 5G. Based on the above characteristics, if the terminal searches that a certain 4G cell is the strongest cell, registering to the 4G cell, but the cell is not configured with a 5G cell; or reselecting the cell with strong signal according to the 4G cell reselection algorithm, but the reselected cell is not configured with 5G; in both cases, the terminal cannot camp on the 5G cell. Therefore, the existing NSA scheme has a certain technical defect in the applicable scene of 5G residence, and is poor in user experience.

Example 1

Fig. 3 is a flowchart of a first embodiment of a non-independent networking residence method of the present invention. The embodiment provides a non-independent networking residence method, which comprises the following steps:

s1, obtaining a first cell sequence according to a first network intensity of each cell;

s2, acquiring second network intensity of each cell, and rearranging the first cell sequence according to the second network intensity to obtain a second cell sequence;

s3, determining the cell where the terminal currently resides according to the second cell ordering.

In this embodiment, a residence method applied to a non-independent networking is provided, where the residence method is divided into two applicable scenarios, one is that cell residence based on the non-independent networking is performed in a terminal startup process, and the other is that neighbor cell residence based on the non-independent networking is performed in a terminal use process when network reselection is performed. In this embodiment, the scenario of the non-independent networking includes the non-independent networking of the 4G network and the 5G network described in the background art, and also includes the non-independent networking of two or more networks adopting similar schemes.

In this embodiment, a description will be given of a case of non-independent networking of a first network and a second network, and it is understood that in the existing non-independent networking scenario of a 4G network and a 5G network, the first network may be a 4G network, and the second network may be a 5G network.

In this embodiment, first, whether a terminal has a network residence requirement in a current network environment is identified and detected, if so, a first network strength of each cell in the current network environment is obtained, where the each cell is determined according to a cell division system in the first network environment, so it can be understood that the first network strength of each cell refers to the network strength of each cell in the first network environment, and then, each cell is ranked according to its corresponding network strength, so as to obtain the first cell ranking in this embodiment. In this embodiment, the network version of the first network is lower than the network version of the second network, for example, the 4G network is behind the 5G network, so in this non-independent scenario, the terminal will preferentially register to the network of the higher network version in order to bring better network experience to the user, while in order to avoid that the network switched to the higher network version cannot bring better user experience to the user because the network coverage of the lower network version is more comprehensive, in this embodiment, the residence mechanism of the lower network version is first used as a basis, and then the residence mechanism of the higher network version is used as a further option for improving the user experience. Specifically, after the first cell rank is obtained according to the first network strength of each cell, the second network strength of each cell is obtained, and the first cell rank is rearranged according to the second network strength to obtain the second cell rank, where, as described above, the second cell rank is substantially determined according to the cell division system in the second network environment, so it can be understood that the second network strength of each cell refers to the network strength of each cell in the second network environment, and then each cell is ranked according to its corresponding network strength, so as to obtain the second cell rank of the embodiment, that is, when the consistency between each cell in the first network environment and each cell in the second network environment is higher, the second cell rank can be regarded as rearrangement of the first cell rank. In this embodiment, after determining the second cell rank of the higher network version, the cells in which the terminal currently resides may be sequentially determined according to the second cell rank, that is, each cell in the second cell rank may be regarded as a higher-version network cell having a network link condition, so switching to each cell in the second cell rank may promote the network version of the terminal, and meanwhile, the network use experience of the user may not be reduced.

Optionally, in this embodiment, the obtaining the first cell rank according to the first network strength of each cell includes:

Optionally, in this embodiment, the obtaining the second network strength of each cell, and rearranging the first cell rank according to the second network strength, to obtain a second cell rank includes:

Optionally, in this embodiment, the acquiring the second network strength of each cell, and rearranging the first cell rank according to the second network strength, to obtain a second cell rank, further includes:

Optionally, in this embodiment, the determining, according to the second cell ranking, a cell in which the terminal currently resides includes:

The method and the device have the advantages that the first cell sequence is obtained according to the first network intensity of each cell, then the second network intensity of each cell is obtained, the first cell sequence is rearranged according to the second network intensity to obtain the second cell sequence, and finally the cell where the terminal currently resides is determined according to the second cell sequence. The network residence scheme is better, the success rate of network residence is improved on the basis of non-independent networking, and the residence network can bring better network experience to users.

Example two

Based on the above embodiments, the present embodiment proposes a network residence scheme based on a 4G network and a 5G network non-independent networking, which is applied to a startup process of a terminal, and specifically includes the following steps:

first, the terminal is started up, and the 4G frequency band supported by the terminal is scanned to obtain the ordering of the signal strength, as shown in the following table 1:

Table 1 4g network cell Power Scan ordering

Then, demodulating each cell according to the sequence from strong to weak according to the signal in the table 1 to obtain the configuration information of the related 5G network in the system message; the 5G network is rearranged according to the message configuring the 5G network, and as shown in the following table 2, the 4G network cell and the 6G network cell are schematically configured in the table 2, in this embodiment, the cell number of the 5G network corresponds to the corresponding 4G network cell, and for convenience of distinction, the cell number of the 5G network and the cell number of the 4G network are processed in unison.

Table 2 4G network cells and 5G network cell configuration ordering

In this embodiment, after the ordering shown in table 2 is completed, the terminal registers the 4G network cells according to the order of table 2, and if a certain cell fails to register, registers the next 4G network cell of the cell in table 2 according to the order of table 2.

In this embodiment, after the terminal registers in the 4G network cell, searching for a corresponding 5G network cell, and completing the access procedure, if successful, camping on the 5G network cell; if the user fails, the 4G network cells are registered according to the sequence of the table 2, so that the basic use experience of the user is ensured.

In another implementation manner of this embodiment, similar to the above scheme of residing on a 5G network based on the current situation of the initial 4G network of the non-independent networking, whether the 4G network cell configures the 5G network does not need to read the 5G network configuration information of each 4G network cell, but after the frequency band of the 4G network is scanned, demodulating (ACQ) to the first 4G network cell, reading all the 5G network information configured by the 4G network cell from the system message, and then, according to the ranking table after the frequency band is scanned, adjusting the ranking in combination with the configuration information of the 5G network, thereby obtaining the network residing priority after the terminal is started.

The method has the advantages that the frequency band scanning is respectively carried out on the 4G network and the 5G network in the starting-up state of the terminal, and the cell sequencing is carried out step by step, so that a network residence scheme which is more suitable for the current network environment is obtained, the success rate of network residence of the terminal in the starting-up process is improved on the basis of non-independent networking, and the network residence of the terminal after the starting-up can bring better network experience to users.

Example III

Based on the first embodiment, the present embodiment proposes a network residence scheme based on a 4G network and a 5G network non-independent networking, which is applied to a network reselection process of a terminal, and specifically includes the following steps:

first, in the use process of the terminal, when the terminal has a network switching condition, the terminal scans the 4G frequency band supported by the terminal to obtain the ordering of the signal intensity, as shown in the following table 3:

table 3 4g network neighbor Power Scan ordering

Then, demodulating each cell according to the sequence from strong to weak according to the signal in the table 3 to obtain the configuration information of the related 5G network in the system message; in the following table 4, the neighbor cell 2, the neighbor cell 4, and the neighbor cell 6 of the 4G network are shown in table 2, and the neighbor cell number of the 5G network corresponds to the neighbor cell of the corresponding 4G network, and for convenience of distinction, the neighbor cell number of the 5G network and the neighbor cell number of the 4G network are processed in a consistent manner.

Table 4 configuration ordering of 4G network neighbors and 5G network neighbors

/>

In this embodiment, after the ranking shown in table 4 is completed, a reselection mechanism adapted to the current network environment is determined, or a reselection mechanism conforming to the characteristics of the current non-independent networking network is determined, and the 4G network cell configured with the 5G network is registered as a higher priority, and at the same time, the original priority reselection algorithm is followed.

In this embodiment, the reselection mechanism is further based on the current network environment, and the reselection parameter is set by the current network, where the purpose of the reselection parameter setting is to reselect to a cell with a better network environment, but it should be understood that, because the reselection parameter of the network is not necessarily reasonable, in this embodiment, the following processing mechanism is provided for network reselection of the terminal: if the current serving cell is detected to be configured with a 5G network and the signal strength of the 5G network is higher than a threshold value, and if the current network environment meets the condition of switching to a 4G network cell without the 5G network, the switching can be omitted, wherein the threshold value of the signal strength is set between-105 and-115.

In this embodiment, the process of reselecting the new cell by the 4G network is consistent with the previous reselection process, and if the new cell and the original cell are in the same TA area, registration is not required; if the TA zone is different from the original service zone, registration needs to be initiated.

In this embodiment, if the reselection fails (for example, ACQ fails, or TAU fails), the procedure returns to the reselection step, so as to determine whether the new neighbor cell meets the determination condition set forth by the reselection mechanism, and the reselection procedure of the terminal network is continuously executed according to the determination result.

In this embodiment, after the terminal registers to a new 4G network cell, searching for a corresponding 5G network cell, and completing the access procedure, if successful, camping on the 5G network cell; if the new neighbor cell fails, judging whether the new neighbor cell meets the reselection condition according to the reselection algorithm of the table 4, so as to continue the reselection flow.

In another implementation manner of this embodiment, similar to the above scheme of residing on a 5G network based on the current situation of the initial 4G network of the non-independent networking, whether the 4G network cell configures the 5G network does not need to read the 5G network configuration information of each 4G network cell, but after the frequency band of the 4G network is scanned, demodulating (ACQ) to the first 4G network cell, reading the 5G network information configured by all the 4G network cells from the system message, and then, according to the ranking table after the frequency band is scanned, adjusting the ranking by combining the configuration information of the 5G network and the reselection mechanism, thereby obtaining the network residence priority when the terminal performs network reselection in the use process.

The method has the advantages that when the terminal is in use, the 4G network and the 5G network are scanned in frequency bands respectively, and cell ordering is implemented step by step, so that a network residence scheme which is more suitable for the current network environment is obtained, and on the basis of non-independent networking, the success rate of network residence of the terminal when in use, in the network reselection is improved, and the network where the terminal resides after the network reselection can bring better network experience to users.
