The specific implementation process of the embodiments of the present application will be described in detail below through a plurality of specific embodiments.

Example 1

Usually, for operator A's 5G terminal, the process of selecting a cell is roughly as follows: operator A's 5G terminal will perform initial network selection after power-on. In the absence of prior information, the terminal usually The frequency point searches the network of operator A, selects a PLMN according to the priority, and then selects the available access network standard and cell for camping under the PLMN, thus completing the initial selection of the cell and the process of camping on the network. Here, for the convenience of description, it can be assumed that the 4G network has a higher priority than the 2G/3G, and the 5G terminal of operator A will reside on the 4G network of operator A.

According to the method provided by the embodiment of this application, in order to make the terminal reselect from the 4G network of operator A to the 5G network of operator B across the operator's cell, the following operations may be performed:

①The 4G network of operator A learns the 5G capability of the UE through the wireless communication capability reported by the UE;

② For a terminal with 5G capability, the 4G network of operator A releases the network connection with the UE through the RRC Connection Release message, and carries one or more of the following network information of operator B in its RRC Connection Release message:

· PLMN information of operator B's 5G network;

·B operator 5G network frequency information;

· Cell reselection priority of B operator's 5G network frequency.

As an example, the specific signaling design in the RRC Connection Release message may be in the following form:

· Operator B supports PLMN (InterOperatorPLMN) of 5G network

·B operator 5G network frequency (InterOperatorCarrierFreq)

·B operator 5G frequency priority (cellReselectionPriority)

③ After receiving the above RRC Connection Release message, the terminal can selectively take at least one of the following actions:

1) Release the connection from the A operator's network;

2) Check whether the 5G network information of operator B is included, such as PLMN, frequency information and/or cell reselection priority and other information;

3) If the 5G network information of operator B is included, the cross-operator cell reselection is regarded as a high priority, and the corresponding frequency point is searched for the PLMN of operator B and a suitable 5G cell to initiate the cell access process; If the InterOperatorCarrierFreq is included in the RRC Connection Release message, the search is performed on the frequency point; if the InterOperatorCarrierFreq is not included, the frequency-by-frequency search is performed. The relative priority between the cross-operator cell reselection and the local operator's cell reselection may be implemented by a network side instruction or a default mode by the UE with a higher priority.

4) If the 5G network information of operator B is not included, the cell reselection of this operator is performed.

④ The base station of operator B can take the following actions after receiving the 4G or 5G network access request initiated by the user of operator A:

1) When the user of operator A is a non-5G user, operator B rejects the user's access request, and optionally sends the rejection reason (such as a non-5G user) to the UE;

2) When the user of operator A is a 5G user, the following two methods can be adopted:

i. If the base station of operator B does not support 5G network (for example, the base station of operator B is 2G, 3G or 4G network that does not support NSA), the user's access request will be rejected, and the reason for rejection (such as the local cell) will be rejected. Does not support 5G network) to UE;

ii. If the base station of operator B supports 5G, the UE is allowed to access. If the base station of operator B is a 4G base station supporting NSA, the 5G NR radiation carrier can be configured to form a dual-connection EN-DC 5G service; if the operator B operates If the commercial base station is a 5G base station that supports SA, it can provide SA 5G services.

Using the above embodiment, the terminal first accesses the network of operator A, carries the network information of operator B through the RRC connection release message, then releases the connection with the network of operator A, and reselects the 5G network of operator B. In this way, A operates The 5G terminal of the operator can access the network of operator B's 5G service and enjoy the 5G service.

In the above-mentioned Embodiment 1, the 5G terminal of operator A first accesses operator A's network (such as a 4G network) according to the regular access network process, and then releases the wireless connection through the RRC connection release process and instructs the UE to access B The operator's 5G network is used to obtain 5G services. The above process requires the terminal to repeatedly initiate the initial access process.

In other embodiments of this application, the network information of operator B can also be carried in the broadcast information of the base station of operator A, and the terminal can read the network information of operator B in the system broadcast message. Therefore, in operator A's 5G terminal During initial access, you can choose to access the 5G network of operator B. The processing procedure is described in detail through Example 2 below.

Example 2

Add at least one of the following information to operator A's system broadcast message: operator B's PLMN information, operator B's network frequency information, and cell reselection priority information. The terminal can search for operator B's 5G at the corresponding frequency. The internet.

For example, the PLMN information of operator B can be added to the system message block type SystemInformationBlockTypeN, wherein,

·SystemInformationBlockTypeN can be existing system information, such as SystemInformationBlockType1, etc., or new system information;

·InterOperatorPlmn-IdentityList contains the list of PLMNs of operator B that operator A's 5G users can choose to access;

·InterOperatorCarrierFreq contains a list of carrier B's 5G network frequency points.

Among them, since a PLMN may correspond to multiple networks, for example, PLMN number 46000 actually corresponds to multiple networks such as 2G/3G/4G. Therefore, after the UE reads the PLMN, it can further specify the network standard it needs to search for. For example: operator B's 4G network (in the case of B operator's NSA network) and/or B operator's 5G network (in the case of B operator's SA network).

The terminal reads the system information of operator A's network in the initial network search. When it contains the 5G network information of the above-mentioned operator B, the terminal with 5G capability will further search for the cell with 5G capability in the PLMN of operator B, and also That is, the 4G cell of the above-mentioned operator B (in the case of the NSA network) and/or the NR cell of the B operator (in the case of the SA network of the B operator).

After the terminal completes the 5G cell search of operator B, it will initiate access in the corresponding cell to complete the camping. The operation after the network of operator B receives the access request initiated by the user of operator A is the same as the processing method in the foregoing Embodiment 1.

Using this embodiment, operator A's 5G terminal can access the 5G network of operator B in the initial cell selection, without first accessing the 4G network of operator A.

In the above-mentioned Embodiment 1 and Embodiment 2, the 5G users of operator A will access the 5G network of operator B according to the cell reselection criteria or the initial cell selection criteria. In some scenarios, for example, because the 4G network of operator A is considered to be of high quality and good coverage, or the power consumption of the 4G network is lower than that of the 5G network, the 5G users of operator A may wish to stay in the 4G network of operator A. , and does not access the network of operator B, in this case, the solution of the following embodiment 3 can be adopted to realize it.

Example 3

Based on the processing in Embodiment 1 or Embodiment 2, the terminal in this embodiment of the present application may also report its own network selection preference preference information to the 4G network of operator A, for example, the terminal prefers to access the network of operator A or prefers to access the network of operator A. Carrier B's network. By reporting the network selection preference, the terminal can have higher autonomy to select the network to access.

As an example, when the terminal initially accesses the non-5G network of operator A, it reports network selection preference preference information. If the terminal prefers to use the 4G network of operator A, the terminal can report the network preference as the 4G network, and A After receiving the preference information of the terminal, the operator's network will not instruct the UE to access the network of operator B.

Further, the terminal may also report network selection conditions corresponding to the network selection preference preference information, and determine whether to access the network of operator B according to whether the network selection conditions are satisfied. Network selection criteria can be set in at least one of the following ways:

Optionally, the network selection condition is a preset rate threshold, for example, when the network rate of operator B is higher than a certain threshold, or the network rate of operator A is lower than a certain threshold, or the terminal service data volume is greater than When a certain threshold is reached, the network can choose to migrate the terminal to the 5G network of operator B;

Optionally, the terminal can independently set the threshold value to notify the network, for example, set conditions such as a rate threshold or a service data volume threshold on the terminal side, and the terminal reports the threshold condition to the network.

Then, after receiving the preference information of the terminal, if the network also receives the corresponding network selection condition, the network instructs the UE to access the network of operator B under the condition that the network selection condition is satisfied.

With the solution of this embodiment, the terminal device can choose whether to access other networks independently to a certain extent, which can meet the needs of a wider range of users.
