Description
Technical Field

Background
There are two ways to share a 5G (5 th-Generation, fifth Generation mobile communication technology) network, namely sharing under NSA (non-independent deployment) architecture and sharing under SA (independent deployment) architecture. For the sharing scheme under the NSA architecture, the implementation is complex. For example, in a certain area, if the 4G signal coverage of the operator a is better, the operator a establishes an NSA network, deploys an NR (New Radio, new air interface) base station, and a user of the operator B can implement a dual connectivity service of a 5G NSA by connecting to a 4G cell and a 5G cell of the operator a. The scheme is a carrier sharing scheme shared by both 4G and 5G cells, wherein the 4G cell of the operator A needs to play two PLMNs (Public Land Mobile networks), namely the operator A and the operator B, so that a user of the operator B can access the 4G anchor point cell of the operator A; then, the 5G cell of operator a also needs to play two PLMNs (operator a and operator B) so that the user of operator B can add a 5G (NR) cell after accessing the 4G (LTE) cell of operator a.
However, considering the NSA architecture, the advantage of 5G NR is mainly the speed increase of data service rate, so that operator B only wants its user B to access the NSA network of operator a when using data service, and still return to its own 4G network when using voice (VoLTE) service.

Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the following describes in detail a service processing method and apparatus under a 5G NSA shared network according to the present invention with reference to the accompanying drawings and embodiments.
Example 1:
as shown in fig. 1, this embodiment provides a service processing method under a 5G NSA shared network, which is applied to a non-shared network device, and the method includes:
In this embodiment, the non-shared network device is a network device of an operator B, the user is a user of the operator B, and the shared network device is a network device of an operator a. The frequency band of the 5G cell of the operator A is NR cell A, the frequency band of the 4G cell (anchor point) is LTE cell A, the 4G and 5G systems broadcast two PLMNs (the main PLMN is A, and the auxiliary PLMN is B), and the LTE cell A and the NR cell A of the operator A are shared base stations of shared carriers and can be accessed by users of the operator B. The 4G cell of operator B is LTE cell B, which is a non-shared independent station. The user service strategy comprises that a user only processes voice service in a non-shared network of an operator to which the user belongs, and processes data service in a mode of non-independently deploying double connections in a shared network of a different operator. Therefore, when the user has a voice service, the user processes the voice service on the non-shared network of the operator B, and after the user finishes the voice service, the user needs to return to the shared network of the different operator. The non-shared network device of the operator B sends the frequency point information of the shared network of the different operator, which satisfies the user service policy, to the user, that is, in this embodiment, the LTE cell B of the operator B sends the frequency point information of the shared LTE cell a and the shared NR cell a of the operator a to the user.
Optionally, before the user ends the voice service, the service processing method in the 5G NSA shared network further includes: and receiving and storing the user service strategy sent by the user.
In this embodiment, the user side stores a user service policy, and the user may transmit the user service policy to the LTE cell through an RRC (Radio Resource Control) air interface signaling for interworking. The user traffic policy also includes a user identity (e.g., IMSI), a public land mobile network identity (PLMN ID) of the user.
Optionally, after receiving and storing the user service policy sent by the user, and before the user finishes the voice service, the service processing method under the 5G NSA shared network further includes: sending the received user service strategy to all the adjacent cells, and receiving feedback information of each adjacent cell, wherein the feedback information comprises frequency point information of each adjacent cell and capability information of whether the feedback information supports non-independent deployment; and acquiring the frequency point information of the shared network of the different operators meeting the user service strategy according to the feedback information.
In this embodiment, the voice service of the user is processed in the non-shared LTE cell B of the operator B, after the non-shared LTE cell B of the operator B receives and stores the user service policy sent by the user, and before the user finishes the voice service, the non-shared LTE cell B of the operator B sends the user service policy to all neighboring cells, and receives neighboring cell frequency point information fed back by each neighboring cell and capability information of whether the neighboring cells support non-independent deployment. And the non-shared LTE cell B of the operator B acquires the frequency point information of the shared network of the different operators, which can meet the user service strategy, from the information fed back by each adjacent cell. Specifically, the non-shared LTE cell B of the operator B detects whether capability information fed back by each neighboring cell supports non-independent deployment; after the capability information that the LTE cell A of the operator A supports the non-independent deployment is detected, the frequency point information of the LTE cell A of the operator A and the frequency point information of the NR cell A corresponding to the LTE cell A are obtained, and the non-shared LTE cell B of the operator B stores the frequency point information of the shared LTE cell A and the shared NR cell A corresponding to the shared LTE cell A, which meet the user service strategy. It should be noted that, when a user is in a mobile state during processing a voice service, a current serving cell of the user needs to always obtain, from a neighboring cell, capability information indicating whether the neighboring cell supports non-independent deployment, and it is ensured that when the user ends a voice call, frequency point information of a shared network of a different operator, which is up-to-date and meets a user service policy, is obtained.
102, receiving a measurement result of measuring the signal quality of the shared network of the different operators by the user according to the frequency point information of the shared network, wherein the measurement result comprises a shared LTE cell meeting the user service strategy and a corresponding shared NR cell.
In this embodiment, after the user receives the frequency point information of the shared LTE cell a and the shared NR cell a corresponding thereto, which satisfy the user service policy and are sent by the unshared LTE cell B of the operator B, the user performs signal quality measurement on the shared LTE cell a and the shared NR cell a corresponding thereto, and reports the measurement result to the unshared LTE cell B of the operator B. The measurement results include shared LTE cell a, shared NR cell a, and their corresponding signal qualities. It should be noted that, since there may be a plurality of frequency point information of the shared network of different operators that satisfy the user service policy, the measurement result obtained by the user measuring the signal quality according to the frequency point information of the shared network may include a plurality of shared LTE cells and their corresponding shared NR cells.
103, initiating a pilot frequency switching request to the shared LTE cell of the different operator according to the measurement result, so that the user is switched to the shared network of the different operator to enter a dual connectivity state.
In this embodiment, the non-shared LTE cell B of the operator B initiates a pilot frequency handover request to the shared LTE cell a of the different operator according to the measurement result reported by the user, where the pilot frequency handover request includes the measurement result. By actively initiating the pilot frequency switching request by the network equipment of the operator to which the user belongs after the user finishes the voice service, the problem that the pilot frequency switching can be triggered only when the signal quality reaches a certain threshold value in the existing mechanism is solved, and the fast pilot frequency switching process is triggered. And because the measurement result also includes the measurement result of the user to the shared NR cell a, when the shared LTE cell a receives the pilot frequency handover request, an auxiliary node addition request is initiated to the shared NR cell a, where the auxiliary node addition request carries the measurement result of the user to the NR cell a. After the NR cell A passes the auxiliary node adding request, the LTE cell A switches the user to the LTE cell A and informs the user to add the NR cell A as an auxiliary node, so that the user can be quickly switched to a shared network of a different operator to enter a double-connection state. Therefore, the user is prevented from sending the operations of measuring the signal quality of the shared NR cell A, reporting the measurement result and the like after switching to the shared LTE cell A. The switching process can be simplified, the switching time is saved, and the service experience of the user is finally improved.
Optionally, when the number of shared LET cells satisfying the user service policy in the measurement result is multiple, selecting one of the multiple shared LET cells with the best signal quality; and initiating a pilot frequency switching request to the selected shared LTE cell.

The frequency band of the 5G cell of the operator A is NR cell A, the frequency band of the 4G cell (anchor point) is LTE cell A, the 4G and 5G systems broadcast two PLMNs (the main PLMN is A, the auxiliary PLMN is B), and the LTE cell A and the NR cell A of the operator A are shared base stations of shared carriers and can be accessed by users of the operator B.
