Detailed Description

The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure.

Unless otherwise specified, "first", "second", and the like in the present disclosure are described to distinguish different objects, and are not intended to mean size, timing, or the like.

In a multi-system network composed of a first-system network and a second-system network, the first-system network equipment is taken as a control point (or anchor point), and combined with the second-system network equipment, hierarchical multi-connection is established according to different priorities of users, so that differentiated shared network service is realized.

Fig. 1 illustrates a flow diagram of a method of establishing a hierarchical multi-connection of some embodiments of the present disclosure.

As shown in fig. 1, the method of this embodiment includes:

in step 110, in a multi-system network formed by a first-system network and a second-system network, a first-system network device receives a connection request sent by a terminal of a user.

The user may be a user of a setting-up operator or a user of a sharing operator.

The first standard network is, for example, a fourth generation mobile network or a third generation mobile network, and the second standard network is, for example, a fifth generation mobile network; accordingly, the first standard network device is, for example, a base station of fourth generation mobile communication (abbreviated as a 4G base station) or a base station of third generation mobile communication (abbreviated as a 3G base station), and the second standard network device is, for example, a base station of fifth generation mobile communication (abbreviated as a 5G base station), but is not limited to the examples.

In step 120, the first-standard network device selects a combination of the connection policy of the first-standard network and the connection policy of the second-standard network in a level corresponding to the priority of the user according to the priority of the user.

The first standard network device may preset a combination of a connection policy of the first standard network and a connection policy of the second standard network at different levels, and then, a combination of a connection policy of the first standard network and a connection policy of the second standard network at a level corresponding to a priority of a user. The higher the priority of the user, the better the performance of the selected combination; where the performance includes coverage performance, capacity performance, or other performance.

Suppose that: the coverage performance is sequentially the first-system network connections 1, 2 and 3 from good to poor, and the capacity performance is sequentially the second-system network connections 1, 2 and 3 from big to small. And selecting a combination of the connection strategy of the first system network and the connection strategy of the second system network at the corresponding level according to the priority of the sharing strategy signed by the user. For example, if the priority of the user a is higher, a combination of the first-system network connection 1 and the second-system network connection 1 may be selected, and if the priority of the user B is lower, a combination of the first-system network connection 2 and the second-system network connection 3 may be selected. But are not limited to, the examples given.

Suppose that: the coverage performance of the first-system network is better than that of the second-system network, the data transmission performance of the second-system network is better than that of the first-system network, the first-system network equipment can be used as a control point (or an anchor point) of a multi-connection network, the connection strategy of the first-system network can be deployed as control plane connection of the first-system network to ensure that a user can normally access the network, on the basis, the user plane connection of the first-system network can be further deployed for a specific user, such as a user of a carrier, and the connection strategy of the second-system network can be deployed as data plane connection of the second-system network. The frequency point of the control plane connection in the control plane connection strategy of the first standard network is lower than the frequency point of the user plane connection in the user plane connection strategy of the second standard network. Therefore, through the multi-connection technology, the performance advantages of the mobile networks of different systems are aggregated to serve the user, the user can enjoy the good coverage performance of the network of the first system and the good data transmission performance of the network of the second system, and the service experience of the user is improved.

The connection strategy of the first standard network comprises at least one connection configuration of the first standard network, and the connection configuration of each first standard network comprises frequency point information and bandwidth information of the first standard network connection.

The connection strategy of the second-standard network comprises at least one connection configuration of the second-standard network, and the connection configuration of each second-standard network comprises frequency point information and bandwidth information of the second-standard network connection.

In some embodiments, the terminal of the user reports the information of the frequency points that can be measured to the network equipment of the first standard, and the network equipment of the first standard selects a combination of the connection policy of the network of the first standard and the connection policy of the network of the second standard at a level corresponding to the priority of the user from the frequency points that can be measured by the terminal of the user. Therefore, the combination of effective connection strategies is selected for the user by combining the frequency point measured by the terminal and the capacity of the terminal for connecting the multiple frequency points simultaneously.

For example, if there is no frequency point of the first-standard network connection 1 in the frequency points that can be measured by the user a with higher priority, the combination of the first-standard network connection 1 and the second-standard network connection 1 cannot be allocated to the user a although the performance level is high, and if the frequency points that can be measured by the user a include the frequency point of the first-standard network connection 2 and the frequency point of the second-standard network connection 1, the suboptimal combination of the first-standard network connection 2 and the second-standard network connection 1 may be allocated to the user a.

In some embodiments, the first-standard network device selects a combination of a connection policy of the first-standard network and a connection policy of the second-standard network, which is of a level corresponding to the priority of the user and is matched with the operator to which the user belongs, according to the priority of the user and the operator to which the user belongs. Therefore, different connection strategy combinations are selected for users of different operators, and differentiated shared network services are provided for the users of different operators.

In some embodiments, the first-standard network device selects, from the frequency point that can be measured by the terminal of the user and the capability of the terminal capable of connecting to multiple frequency points at the same time, a combination of a connection policy of the first-standard network and a connection policy of the second-standard network, which is in a level corresponding to the priority of the user and is matched with the operator to which the user belongs, according to the priority of the user and the operator to which the user belongs. Therefore, the method can select an effective combination of the connection strategies for the user and provide differentiated shared network service for the users of different operators.

The scheme of selecting a combination of connection policies according to the operator to which the user belongs will be described in detail later in connection with the embodiment shown in fig. 2.

In step 130, the first-standard network device establishes at least one first-standard network connection with the terminal of the user according to the connection policy of the first-standard network.

If the connection strategy of the first standard network comprises the connection configuration of the first standard network, the first standard network equipment establishes a first standard network connection with the terminal of the user according to the connection configuration of the first standard network.

If the connection strategy of the first standard network comprises the connection configuration of a plurality of first standard networks, the first standard network equipment establishes a plurality of first standard network connections with the terminal of the user respectively according to the connection configuration of the plurality of first standard networks.

In step 140, the first-system network device notifies the second-system network device of the information of the connection policy of the second-system network, so that the second-system network device establishes at least one second-system network connection with the user terminal according to the connection policy of the second-system network.

And if the connection strategy of the second system network comprises a connection configuration of the second system network, the second system network equipment establishes a second system network connection with the terminal of the user according to the connection configuration of the second system network.

And if the connection strategy of the second system network comprises the connection configuration of a plurality of second system networks, the second system network equipment respectively establishes a plurality of second system network connections with the user terminal according to the connection configuration of the plurality of second system networks.

In the embodiment, in a multi-system network composed of a first-system network and a second-system network, the first-system network device is used as a control point (or anchor point) and is combined with the second-system network device to establish hierarchical multi-connection according to different priorities of users, so that differentiated shared network services are realized.

Fig. 2 shows a flow diagram of a method of establishing a hierarchical multi-connection according to further embodiments of the present disclosure.

As shown in fig. 2, the method of this embodiment includes:

in step 210, in a multi-system network formed by a first-system network and a second-system network, a first-system network device receives a connection request sent by a terminal of a user.

In step 220, the first standard Network device determines that an operator to which the user belongs is a carrier operator or a shared operator according to a Public Land Mobile Network (PLMN) number sent by the terminal of the user.

The PLMN number includes MCC (Mobile Country Code) and MNC (Mobile Network Code), and the operator to which the user belongs may be determined by the MNC.

The first standard network device obtains the PLMN number from a connection request sent by a terminal of a user, for example.

In step 230, the first-standard network device selects a combination of the connection policy of the first-standard network and the connection policy of the second-standard network, which is in a level corresponding to the priority of the user and is matched with the operator to which the user belongs, according to the priority of the user and the operator to which the user belongs.

230 a: when the user belongs to a carrier operator, the selected connection strategy of the first standard network comprises a control plane connection strategy and a user plane connection strategy of the first standard network, and the selected connection strategy of the second standard network comprises a user plane connection strategy of the second standard network.

230 b: when the user belongs to the shared operator, the selected connection strategy of the first standard network comprises a control plane connection strategy of the first standard network, and the selected connection strategy of the second standard network comprises a user plane connection strategy of the second standard network.

In step 240, when the user belongs to the carrier, the network device of the second standard performs the second-standard operation according to the user plane connection policy of the network of the second standard notified by the network device of the first standard, establishing at least one user plane connection of the second-system network with the terminal of the user (step 240a), the first-system network equipment according to the control plane connection strategy and the user plane connection strategy of the first-system network, establishing at least one control plane connection and at least one user plane connection of a first system network with a terminal of a user, and turns on the shunting switch for shunting user plane data to at least one user plane connection of the first system network connected to at least one user plane of the second system network (step 240b), and the user plane data of the user can be transmitted in at least one user plane connection of the first system network and at least one user plane connection of the second system network.

In step 250, when the user belongs to the shared operator, the second-system network device establishes at least one user plane connection of the second-system network with the terminal of the user according to the user plane connection policy of the second-system network notified by the first-system network device (step 250a), the first-system network device establishes at least one control plane connection of the first-system network with the terminal of the user according to the control plane connection policy of the first-system network, and closes a shunting switch for shunting user plane data from the second-system network to the first-system network (step 250b), so that the user plane data of the user can be transmitted in the at least one user plane connection of the second-system network.

Therefore, different connection strategy combinations are selected for users of different operators, and differentiated shared network services are provided for the users of different operators.

The multi-connection network includes a core network and an access network, and the access network generally adopts a network architecture with a separation of a control plane and a user plane. Taking an NSA (Non-standard one, Non-independent networking) dual connectivity scheme of a 5G mobile network as an example, since a deployment frequency point of a 4G base station is lower than that of a 5G base station, the coverage area of the 4G base station is larger than that of the 5G base station, in the NSA dual connectivity scheme, the 4G base station is responsible for control plane signaling transmission, and the 5G base station and the 4G base station are jointly responsible for user plane data transmission through a dual connectivity technology, so as to achieve the purpose of aggregating the performance of the 4G and 5G mobile networks. The Protocol stacks of the 4G base station and the 5G base station include, for example, a PDCP (Packet Data Convergence Protocol) layer, an RLC (Radio Link Control) layer, an MAC (Media Access Control) layer, a PHY (Physical) layer, and the like. The 4G base station and the 5G base station are both connected to an EPC (Evolved Packet Core). The 4G base station is, for example, an LTE (Long Term Evolution) base station, and the 5G base station is, for example, an NR (New Radio, New air interface) base station.

It is assumed that the coverage performance is sequentially a control plane connection 1, 2, 3 of the first-system network from good to poor, the capacity performance is sequentially a user plane connection 1, 2, 3 of the first-system network from large to small, and the capacity performance is sequentially a user plane connection 1, 2, 3 of the second-system network from large to small. And selecting a combination of the connection strategy of the first system network and the connection strategy of the second system network at the corresponding level according to the priority of the sharing strategy signed by the user.

As shown in fig. 3A, if the user a is a user of a shared operator and the priority of the user a is higher, the shunting switch for shunting the user plane data from the second-standard network (e.g., 5G network) to the first-standard network (e.g., 4G network) is turned off, so that a combination of the control plane connection 1 of the first-standard network and the user plane connection 1 of the second-standard network may be selected, the control plane signaling is transmitted through the control plane connection 1 of the first-standard network, and the user plane data is transmitted only through the user plane connection 1 of the second-standard network. The transmission of control plane signalling is shown by the dashed arrow and the transmission of user plane data is shown by the solid arrow.

As shown in fig. 3B, if the user B is a user of the carrier, and the priority of the user B is higher, the shunting switch for shunting the user plane data to the first system network (e.g., 4G network) by the second system network (e.g., 5G network) is turned on, so that a combination of the control plane connection 1 and the user plane connection 1 of the first system network and the user plane connection 1 of the second system network can be selected, the control plane signaling is transmitted through the control plane connection 1 of the first system network, and the user plane data is simultaneously transmitted through the user plane connection 1 of the first system network and the user plane connection 1 of the second system network. The transmission of control plane signalling is shown by the dashed arrow and the transmission of user plane data is shown by the solid arrow.
