[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 descriptions "first", "second", etc. in this disclosure are used to distinguish 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 combined with a second mode network device as a control point (or anchor point) to establish hierarchical multiple connections according to different priorities of users, thereby realizing differentiated shared network services.

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

[0025] As shown in FIG. 1, the method of this embodiment includes 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. Thus, 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 of the first mode network and a connection policy of 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 preset combinations of different levels of the first mode network connection policy and the second mode network connection policy, and select a combination of the first mode network connection policy and the second mode network connection policy of a level according to a user's priority. The higher the user's priority, the more improved the performance, including coverage performance, capacity performance, or other performance, of the selected combination can be.

[0031] Assume that the first mode network connections are Connection 1, Connection 2, and Connection 3 in order of good to bad coverage performance, and the second mode network connections are Connection 1, Connection 2, and Connection 3 in order of large to small capacity performance. A combination of a connection policy of the first mode network and a connection policy of the second mode network at a corresponding level is selected according to the priority of a shared policy signed by a user. For example, if the priority of user A is high, a combination of the first mode network connection 1 and the second mode network connection 1 can be selected, and if the priority of user B is low, a combination of the first mode network connection 2 and the second mode network connection 3 can be selected. Note that these are merely examples, and the selection of the combination 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 a control plane connection of the first mode network, so that users can normally access the network, and based on these, the user plane connection of the first mode network can be further deployed for a specific user, such as a user of a contracted carrier, and the connection policy of the second mode network can be deployed as a data plane connection (i.e., user plane connection) of the second mode network. The frequency of the control plane connection in the control plane connection policy of the first mode network The number is The frequency of user plane connection in the user plane connection policy of the second mode network NumbersTherefore, the multiple access technology can aggregate the performance advantages of different modes of mobile networks to provide services to users, so that users can not only enjoy the good coverage performance of the first mode network, but also enjoy the good data transmission performance of the second mode network, thereby improving the user's 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 defines a frequency of one first mode network connection. Number The information includes the number of times ...

[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 defines a frequency of one second mode network connection. Number The information includes the number of times ...

[0035] In some embodiments, the user's terminal is Number The first mode network device reports the frequency that the user's terminal can measure to the first mode network device. Number From among the above, a combination of a connection policy for the first mode network and a connection policy for the second mode network at a level according to the user's priority is selected. Number and , multiple frequencies Number Combined with the terminal's capabilities for simultaneous connections, an effective combination of connection policies is selected for the user.

[0036] For example, the frequency that user A, who has a high priority, can measure In number In the first mode of network connection, The number If not, the combination of the first mode network connection 1 and the second mode network connection 1 has a high performance level but cannot be assigned to user A, and the frequency that user A can measure is not available. In numberIn the first mode of network connection, the two frequencies Number and 1 frequency of the second mode network connection The number If so, user A may be assigned a non-optimal combination of 2 first mode network connections and 1 second mode network connection.

[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 priority of the user according to a 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 network device in the first mode receives a frequency measurable at a user's terminal. Number and , multiple frequencies Number Based on the capabilities of simultaneously connecting terminals, a combination of a connection policy for a first mode network and a connection policy for a second mode network that matches the operator to which the user belongs at a level corresponding to the user's priority is selected according to the priority of the user and the operator to which the user belongs. This makes it possible not only to select a combination of connection policies that is effective for the user, but also to provide differentiated shared network services to users of different operators.

[0039] A solution for selecting a combination of connection policies depending on the service provider 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 a 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's terminal according to the 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 of 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's 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's terminal according to the 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) in combination 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 multiple 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 a 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 connectivity policy selected in the first mode network comprises a control plane connectivity policy and a user plane connectivity policy of the first mode network, and the connectivity policy selected 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 from 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 for shunting 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 as to transmit the user's user plane data 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 transmit the user plane data of the user on 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, providing differentiated shared network services for the users of different operators.

[0059] A multi-connection network is composed of a core network and an access network, and the access network generally adopts a network architecture in which the control plane and the user plane are separated. Taking the NSA (Non-Standalone) dual connection solution of the 5G mobile network as an example, The number isSince the coverage area of ​​4G base stations is smaller than that of 5G base stations and larger than that of 5G base stations, in the NSA dual connection solution, the 4G base station is responsible for transmitting control plane signaling, and the 5G base station and the 4G base station are jointly responsible for transmitting user plane data through dual connection technology, thereby achieving the purpose of consolidating the performance of 4G and 5G mobile networks. The protocol stack of the 4G base station and the 5G base station is composed of, for example, a Packet Data Convergence Protocol (PDCP) layer, a Radio Link Control (RLC) layer, a Media Access Control (MAC) layer, a Physical (PHY) layer, etc. Both the 4G base station and the 5G base station are connected to an 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 good to bad coverage performance, the user plane connections of the first mode network are Connection 1, Connection 2, and Connection 3 in order of high to low capacity performance, and the user plane connections of the second mode network are Connection 1, Connection 2, and Connection 3 in order of high to low capacity performance. A 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 operator and has 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., 5G network) to the first mode network (e.g., 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. 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.

[0062] As shown in Figure 3B, when User B is a user of the contracted operator and User B has a 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., 5G network) to the first mode network (e.g., 4G network), and 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 dashed arrows, and the transmission of user plane data is indicated by solid arrows.
