[0021] The technical solutions in the embodiments of the present disclosure are clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure.

[0022] Unless otherwise specified, the terms "first," "second," etc. in this disclosure are used to distinguish between different objects and are not intended to represent size, order, etc.

[0023] According to the present disclosure, in a multi-mode network formed by a first mode network and a second mode network, a first mode network device is used as a control point (or anchor point) in combination with a second mode network device, thereby establishing hierarchical multiple connections according to different user priorities, thereby realizing differentiated shared network services.

[0024] FIG. 1 illustrates a schematic flow diagram of a method for establishing hierarchical multiplexed connections according to some embodiments of the present disclosure.

[0025] As shown in FIG. 1, the method of this embodiment is composed of steps 110 to 140.

[0026] In step 110, in a multi-mode network consisting of a first-mode network and a second-mode network, a first-mode network device receives a connection request sent from a user terminal.

[0027] The user here may be a user of the contracted business operator or a user of the shared business operator.

[0028] The first mode network is, for example, a fourth generation mobile network or a third generation mobile network, and the second mode network is, for example, a fifth generation mobile network. Therefore, the first mode network device is, for example, a fourth generation mobile communication base station (abbreviated as 4G base station) or a third generation mobile communication base station (abbreviated as 3G base station), and the second mode network device is, for example, a fifth generation mobile communication base station (abbreviated as 5G base station), but these devices are not limited to those exemplified.

[0029] In step 120, the first mode network device selects a combination of a connection policy for the first mode network and a connection policy for the second mode network at a level corresponding to the user's priority, according to the user's priority.

[0030] The first-mode network device can pre-configure combinations of different levels of first-mode network connection policies and second-mode network connection policies, and select a combination of the first-mode network connection policy and the second-mode network connection policy at a level according to a user's priority, where the higher the user's priority, the better the performance, including coverage performance, capacity performance, or other performance, of the selected combination.

[0031] Assume that the first mode network connections are numbered Connection 1, Connection 2, and Connection 3 in order of coverage performance from best to worst, and the second mode network connections are numbered Connection 1, Connection 2, and Connection 3 in order of capacity performance from highest to lowest. A combination of a first mode network connection policy and a corresponding level of a second mode network connection policy is selected according to the priority of a shared policy signed by a user. For example, if user A has a high priority, the combination of first mode network connection 1 and second mode network connection 1 can be selected, and if user B has a low priority, the combination of first mode network connection 2 and second mode network connection 3 can be selected. Note that these are merely examples, and the selection of combinations is not limited to these examples.

[0032] Assume that the coverage performance of the first mode network is superior to that of the second mode network, the data transmission performance of the second mode network is superior to that of the first mode network, the first mode network device is a control point (or anchor point) of a multi-connection network, and the connection policy of the first mode network is deployed as the control plane connection of the first mode network, allowing users to access the network normally. Based on these, the user plane connection of the first mode network can be further deployed for specific users, such as users of a contracted carrier, and the connection policy of the second mode network can be deployed as the data plane connection (i.e., user plane connection) of the second mode network. The frequency point of the control plane connection in the control plane connection policy of the first mode network is smaller than the frequency point of the user plane connection in the user plane connection policy of the second mode network. Therefore, the multiple access technology aggregates the performance advantages of different modes of mobile networks to provide services to users, allowing users to enjoy not only the good coverage performance of the first mode network but also the good data transmission performance of the second mode network, thereby improving the user service experience.

[0033] The connection policy of the first mode network comprises at least one connection configuration of the first mode network, and each connection configuration of the first mode network comprises frequency point information and bandwidth information of one first mode network connection.

[0034] The connection policy of the second mode network comprises at least one connection configuration of the second mode network, and each connection configuration of the second mode network comprises frequency point information and bandwidth information of one second mode network connection.

[0035] In some embodiments, the user terminal reports information about measurable frequency points to the first-mode network device, and the first-mode network device selects a combination of a first-mode network access policy and a second-mode network access policy at a level according to the user's priority from among the frequency points measurable by the user terminal, thereby selecting an effective combination of access policies for the user based on the frequency points measurable by the terminal and the terminal's ability to simultaneously connect to multiple frequency points.

[0036] For example, if there is no frequency point of the first mode network connection 1 among the frequency points that a high-priority user A can measure, the combination of the first mode network connection 1 and the second mode network connection 1 cannot be allocated to user A, even though it has a high performance level; if there are frequency points of the first mode network connection 2 and the second mode network connection 1 among the frequency points that user A can measure, a non-optimal combination of the first mode network connection 2 and the second mode network connection 1 can be allocated to user A.

[0037] In some embodiments, the first mode network device selects a combination of a connection policy of the first mode network and a connection policy of the second mode network that matches the operator to which the user belongs at a level corresponding to the user's priority according to the priority of the user and the operator to which the user belongs, so that different combinations of connection policies are selected for users of different operators, and differentiated shared network services are provided for users of different operators.

[0038] In some embodiments, the first-mode network device selects a combination of a connection policy of the first-mode network and a connection policy of the second-mode network that matches the operator to which the user belongs, at a level corresponding to the user's priority, based on the frequency points measurable by the user's terminal and the terminal's ability to simultaneously connect to multiple frequency points, according to the priority of the user and the operator to which the user belongs. This not only enables the selection of an effective combination of connection policies for the user, but also enables the provision of differentiated shared network services to users of different operators.

[0039] A solution for selecting a combination of connection policies depending on the operator to which the user belongs will be described later in conjunction with the embodiment shown in FIG.

[0040] In step 130, the first-mode network device establishes at least one first-mode network connection with the user's terminal according to the connection policy of the first-mode network.

[0041] When the connection policy of the first mode network includes one connection configuration of the first mode network, the first mode network device establishes one first mode network connection with the user terminal according to one connection configuration of the first mode network.

[0042] When the connection policy of the first mode network includes multiple connection configurations of the first mode network, the first mode network device establishes multiple first mode network connections with the user's terminal according to the multiple connection configurations of the first mode network.

[0043] In step 140, the first mode network device notifies the second mode network device of information about the connection policy of the second mode network, and the second mode network device establishes at least one second mode network connection with the user terminal according to the connection policy of the second mode network.

[0044] When the connection policy of the second mode network includes one connection configuration of the second mode network, the second mode network device establishes one second mode network connection with the user terminal according to one connection configuration of the second mode network.

[0045] When the connection policy of the second mode network includes multiple connection configurations of the second mode network, the second mode network device establishes multiple second mode network connections with the user's terminal according to the multiple connection configurations of the second mode network.

[0046] In the above embodiment, in a multi-mode network consisting of a first mode network and a second mode network, a first mode network device is used as a control point (or anchor point) and combined with a second mode network device to establish hierarchical multiple connections according to the priorities of different users, thereby realizing differentiated shared network services.

[0047] FIG. 2 shows a schematic flow diagram of a method for establishing hierarchical multiplexed connections according to another embodiment of the present disclosure.

[0048] As shown in FIG. 2, the method of this embodiment comprises the following steps:

[0049] In step 210, in a multi-mode network consisting of a first-mode network and a second-mode network, a first-mode network device receives a connection request sent from a user terminal.

[0050] In step 220, the first mode network device determines that the operator to which the user belongs is a contract operator or a shared operator according to the Public Land Mobile Network (PLMN) number sent from the user's terminal.

[0051] The PLMN number includes a Mobile Country Code (MCC) and a Mobile Network Code (MNC), and the MNC determines the operator to which the user belongs.

[0052] The network device in the first mode obtains the PLMN number, for example, from a connection request sent from the user's terminal.

[0053] In step 230, the first mode network device selects a combination of a connection policy of the first mode network and a connection policy of the second mode network that matches the operator to which the user belongs, at a level according to the user's priority, depending on the priority of the user and the operator to which the user belongs.

[0054] In step 230a, if the user belongs to a contracted carrier, the selected connectivity policy in the first mode network comprises a control plane connectivity policy and a user plane connectivity policy of the first mode network, and the selected connectivity policy in the second mode network comprises a user plane connectivity policy of the second mode network.

[0055] In step 230b, if the user belongs to a shared operator, the selected connectivity policy in the first mode network comprises a control plane connectivity policy of the first mode network, and the selected connectivity policy in the second mode network comprises a user plane connectivity policy of the second mode network.

[0056] In step 240, if the user belongs to the contracted carrier, the second mode network device establishes at least one user plane connection of the second mode network with the user's terminal in accordance with the user plane connection policy of the second mode network notified by the first mode network device (step 240a), and the first mode network device establishes at least one control plane connection and at least one user plane connection of the first mode network with the user's terminal in accordance with the control plane connection policy and user plane connection policy of the first mode network, and turns on a shunt switch to shunt user plane data from the at least one user plane connection of the second mode network to the at least one user plane connection of the first mode network (step 240b), so that the user's user plane data can be transmitted through the at least one user plane connection of the first system network and the at least one user plane connection of the second system network.

[0057] In step 250, if the user belongs to a shared operator, the second mode network device establishes at least one user plane connection of the second mode network with the user's terminal in accordance with the user plane connection policy of the second mode network notified by the first mode network device (step 250a), and the first mode network device establishes at least one control plane connection of the first mode network with the user's terminal in accordance with the control plane connection policy of the first mode network, and turns off a shunt switch for shunting user plane data from the second mode network to the first mode network (step 250b), so as to enable the user's user plane data to be transmitted over at least one user plane connection of the second mode network.

[0058] Therefore, different combinations of connection policies are selected for users of different operators, and differentiated shared network services are provided for users of different operators.

[0059] A multi-connection network consists of a core network and an access network, with the access network typically adopting a network architecture with separate control and user planes. Taking the non-standalone (NSA) dual-connection solution of a 5G mobile network as an example, 4G base stations have fewer deployed frequency points than 5G base stations, but their coverage area is larger than that of 5G base stations. Therefore, in the NSA dual-connection solution, 4G base stations are responsible for transmitting control plane signaling, while 5G and 4G base stations jointly transmit user plane data using dual-connection technology, thereby achieving the goal of integrating the performance of 4G and 5G mobile networks. The protocol stacks of 4G and 5G base stations consist of, for example, the Packet Data Convergence Protocol (PDCP) layer, Radio Link Control (RLC) layer, Media Access Control (MAC) layer, and Physical Layer (PHY) layer. Both 4G and 5G base stations are connected to the Evolved Packet Core (EPC). The 4G base station is, for example, a Long Term Evolution (LTE) base station, and the 5G base station is, for example, a New Radio (NR) base station.

[0060] Assume that the control plane connections of the first mode network are Connection 1, Connection 2, and Connection 3 in order of coverage performance from best to worst, the user plane connections of the first mode network are Connection 1, Connection 2, and Connection 3 in order of capacity performance from highest to lowest, and the user plane connections of the second mode network are Connection 1, Connection 2, and Connection 3 in order of capacity performance from highest to lowest. The combination of the connection policy of the first mode network and the connection policy of the second mode network at the corresponding level is selected according to the priority of the shared policy signed by the user.

[0061] As shown in Figure 3A, when User A is a user of a shared carrier and User A has a high priority, a combination of control plane connection 1 of the first mode network and user plane connection 1 of the second mode network can be selected by turning off a shunt switch for shunting user plane data from the second mode network (e.g., a 5G network) to the first mode network (e.g., a 4G network), and control plane signaling is transmitted via control plane connection 1 of the first mode network, and user plane data is transmitted only via user plane connection 1 of the second mode network. Transmission of control plane signaling is indicated by dashed arrows, and transmission of user plane data is indicated by solid arrows.

[0062] As shown in Figure 3B, when User B is a user of the contracted carrier and has high priority, a combination of Control Plane Connection 1 and User Plane Connection 1 of the first mode network and User Plane Connection 1 of the second mode network can be selected by turning on a shunt switch for shunting user plane data from the second mode network (e.g., a 5G network) to the first mode network (e.g., a 4G network), in which control plane signaling is transmitted via Control Plane Connection 1 of the first mode network and user plane data is transmitted via User Plane Connection 1 of the first mode network and User Plane Connection 1 of the second mode network simultaneously. The transmission of control plane signaling is indicated by a dashed arrow and the transmission of user plane data is indicated by a solid arrow.
