The above network architectures are merely exemplary and do not represent any limitation on the present invention. Those skilled in the art may make modifications to the specific network architecture used, or use other network architectures, as desired.

The UE11 has no authority to access network a. But if the user is signed up for a third party service and network a and the third party service are able to provide third party authorization services to local network, the user may be given access to local network a and provided with paging, handover, etc. operations by devices in local network a. This functionality is not supported in the current 5G standard.

In order to realize the function, the invention defines the service identification of the third party authentication authorized service provider (referred to as the third party service provider for short), the information can be presented in a list form and is transmitted in the mutual information between the base station and the core network, the base station and the terminal, and the base station, so as to represent the third party service provider supported, allowed or selected by the sender or the related party of the information.

In some embodiments, the service identification of the third party facilitator includes a service identification of a third party verification authority facilitator supported by the public network and a service identification of a third party verification authority facilitator supported by the non-public network.

In some embodiments, priority information for the identification may also be included in the list of identifications for selection with reference to priority when the user supports multiple third party vendors.

In some embodiments, the service identifier list of the third party service provider includes at least one of a plurality of SNPN (Stand-alone Non-Public Network identifiers, Non-Public Network identifiers of Non-independent networks, and PLMN (Public Land Mobile Network) identifiers, and the order of the service identifiers (SNPN identifiers or PLMN identifiers) in the list may implicitly reflect the priority information of the Network.

Embodiments of the present invention may perform a variety of interactions including the service identification of a third party facilitator. An embodiment of the network service method of the present invention is described below with reference to fig. 2A.

FIG. 2A illustrates a flow diagram of a network service method according to some embodiments of the invention. As shown in fig. 2A, the network service method of this embodiment includes steps S202 to S204.

In step S202, the first base station receives a first inter-base station bearer message sent by the second base station, where the first inter-base station bearer message includes an identifier of a third party service provider supported by a cell of the second base station.

In some embodiments, the first inter-base station bearer message is an interface SETUP REQUEST message (XN SETUP REQUEST).

In some embodiments, the first inter-base station bearer message is a base station information UPDATE request message (NG-RAN NODE CONFIGURATION UPDATE).

In step S204, the first base station stores the identification of the third party facilitator supported by the cell of the second base station. Thus, the first base station is able to perform subsequent paging, handover, etc. operations involving the second base station based on the stored information.

By the method of the above embodiment, the network operator can make an unauthorized user obtain network service by mutually authorizing with the industry vertical network or the third party network, for example, make a public user obtain a private network service, or provide a private network user with service under other networks. The base station can provide service for the user by interacting with the identification of the third party service provider. Therefore, the user can enjoy the cross-network service, and the flexibility of the network service is improved.

In some embodiments, the first base station may also send the identification of the third party facilitator that it supports to the second base station. FIG. 2B illustrates a flow diagram of a network service method according to some embodiments of the inventions. As shown in fig. 2B, the network service method of this embodiment includes steps S202 to S208.

In step S202, the first base station receives a first inter-base station bearer message sent by the second base station.

In step S204, the first base station stores the identification of the third party facilitator supported by the cell of the second base station.

In step S206, the first base station sends a second inter-base station bearer message to the second base station, where the second inter-base station bearer message includes an identifier of a third party service provider supported by the cell of the first base station.

In step S208, the second base station stores the identity of the third party facilitator supported by the cell of the first base station. Thereby, the second base station is able to perform subsequent paging, handover, etc. operations involving the first base station based on the stored information.

In some embodiments, the first inter-base station bearer message and the second inter-base station bearer message are a set of corresponding messages. For example, the first inter-base station bearer message is an interface SETUP REQUEST message (XN SETUP REQUEST), and the second inter-base station bearer message is an interface SETUP confirmation message (XN SETUP RESPONSE); or, the first inter-base-station bearer message is a base station information UPDATE request message (NG-RAN NODE CONFIGURATION UPDATE) and the second inter-base-station bearer message is a base station information UPDATE confirm message (NG-RAN NODE CONFIGURATION UPDATE ACKNOWLEDGE).

Therefore, the identification of the third-party service provider can be interacted by utilizing the interaction processes of interface establishment, information updating and the like, so that different base stations can know the supporting condition of the third-party service provider by the other side in advance, and the processing speed of the subsequent operation process is improved.

Through the above inter-base station interaction process, the first base station knows the third party service provider supported by the cell of the second base station. When the user under the first base station is to execute the handover, the first base station can decide whether to initiate the handover process according to the support situation of the target cell grasped by the first base station to the third-party service provider.

In some embodiments, the first base station obtains an identification of a third party service provider allowed by the user from the core network to facilitate paging, handover, and the like. An embodiment of the user information acquisition method of the present invention is described below with reference to fig. 3.

FIG. 3 illustrates a flow diagram of a method of user information acquisition, according to some embodiments of the invention. As shown in fig. 3, the user information acquisition method of this embodiment includes steps S302 to S304.

In step S302, the first base station acquires user information sent by the core network device, where the user information includes an identifier of a third-party service provider allowed by the user.

In some embodiments, the user information is carried using an INITIAL CONTEXT SETUP REQUEST message (INITIAL CONTEXT SETUP REQUEST), and the first base station may perform feedback through an INITIAL CONTEXT SETUP RESPONSE message (INITIAL CONTEXT SETUP RESPONSE); or, the user information is carried by using a DOWNLINK non-access stratum TRANSPORT message (DOWNLINK NAS TRANSPORT).

In step S304, the first base station stores the identification of the third party service provider allowed by the user.

Therefore, the base station can acquire the identification of the third-party service provider allowed by the user from the core network to assist paging, switching and other operations.

In some embodiments, the first base station initiates a process of handing over a user accessing a cell of the first base station to a target cell, wherein the identifier of the third party service provider supported by the target cell stored by the first base station comprises an identifier of the third party service provider selected or allowed by the user.

In some embodiments, the target cell is a cell of the second base station. Further, the target cell may also be the first base station's own cell.

In some embodiments, the following method may be adopted to implement the user access process: the base station sends a broadcast message, wherein the broadcast message comprises the identification of a third-party service provider supported by both a cell of the base station and core network equipment; the base station receives an access request sent by a terminal of a user, wherein a third-party service provider in the broadcast message comprises a third-party service provider supported by the user; the base station obtains the identifier of the third-party service provider selected by the terminal; the base station sends a terminal authentication request to the core network equipment, wherein the terminal authentication request comprises an identifier of a third-party service provider selected by the terminal; and responding to the core network equipment passing the terminal authentication request, and allowing the terminal to access by the base station. After the terminal accesses, the handover procedure may be performed as needed.

An embodiment of the handover method of the present invention is described below with reference to fig. 4 and 5.

Fig. 4 shows a flow diagram of a handover method according to some embodiments of the invention. As shown in fig. 4, the handover method of the embodiment relates to a core network, and includes steps S402 to S406.

In step S402, the first base station sends a first handover request of the user to the core network device, where the first handover request includes an identifier of a target cell to which the user intends to handover. In some embodiments, the first HANDOVER request is a user HANDOVER request message (HANDOVER requested).

The target cell is exemplarily illustrated in fig. 4 as being located at the second base station. The target cell may also be located at the first base station, depending on the actual handover scenario.

In step S404, in a case that the target cell does not support the third-party service provider allowed by the user, the core network device sends a HANDOVER FAILURE message (e.g., HANDOVER FAILURE) to the first base station.

And for the condition that the target cell is positioned at the second base station, the first base station stores the third party service providers supported by the second base station through pre-interaction. However, it may happen that the third party service provider supported by the second base station changes, and the first base station is not up to date. In this case, there is a possibility that the handover fails.

In step S406, in the case that the target cell supports the third-party service provider allowed by the user, the core network device sends a second handover request to the target cell.

By the method of the embodiment, the core network can determine whether to request the target cell to perform handover according to the support condition of the target cell to the third-party service provider by the user requesting handover. Therefore, the success rate of switching is improved, and the user experience is improved.

In some embodiments, after step S404, the handover method further includes step S408.

In step S408, in case of receiving the handover failure message sent by the core network, the first base station updates the stored identifier of the third party service provider supported by the target cell, where the identifier corresponds to a case where the target cell is located in the second base station. The handover failure message includes an identifier of a third party service provider supported by the target cell.

Therefore, the first base station can respond to the switching failure and update the information stored by the first base station in time. The subsequent first base station may not initiate handover to the target cell temporarily according to the stored information.

In some embodiments, after step S406, the handover method further includes step S410. In this embodiment, the second handover request includes an identifier of a third-party service provider allowed or selected by the user requesting the handover and an identifier of a target cell to be handed over by the user.

The third-party service provider allowed by the user refers to a third-party service provider which the user has signed up and can be used, and the third-party service provider selected by the user refers to a third-party service provider used when the user is currently accessed to the network.

In some embodiments, if the user informs the third-party service provider selected by the core network at the time of access, the second handover request includes an identifier of the third-party service provider selected by the user; if the user does not inform the third-party service provider selected by the core network during access, but only informs the third-party service provider allowed by the user, the second handover request includes the identification of the third-party service provider allowed by the user.

In step S410, in case that the third-party service provider allowed or selected by the user requesting HANDOVER is different from the third-party service provider supported by the cell of the second base station, the second base station sends a HANDOVER FAILURE message (e.g., HANDOVER FAILURE) to the core network.

The core network stores the third party service providers supported by each base station. However, it may happen that the third party service provider supported by the base station changes and the core network and other base stations are not up to date. In this case, there is a possibility that the handover fails. Therefore, the second base station can feed back the situation in time, so that the situation that the user cannot continue to use the network service when the user is switched to the cell of the second base station is avoided, and the user experience is improved.

Fig. 5 is a flow chart illustrating a handover method according to further embodiments of the present invention. As shown in fig. 5, the handover method of this embodiment describes handover (e.g., Xn handover) between base stations, and includes steps S502 to S504.

In step S502, the first base station sends a third handover request message to the second base station, where the third handover request message includes an identifier of a target cell to which the user intends to handover and an identifier of a third-party service provider allowed or selected by the user.

The third HANDOVER REQUEST message is a HANDOVER REQUEST message in case an Xn interface exists between the first base station and the second base station.

In step S504, in the case that the target cell supports the third party service provider allowed or selected by the user, the second base station sends a HANDOVER REQUEST ACKNOWLEDGE message (e.g., HANDOVER REQUEST ACKNOWLEDGE) to the first base station.

Therefore, when the target cell of the second base station supports the identifier of the third-party service provider allowed or selected by the user, the second base station receives the switching, and the success rate of the switching and the user experience are improved.

In some embodiments, the handover method further comprises step S506.

In step S506, the second base station stores the identifier of the third-party service provider allowed or selected by the user, so as to be used for subsequent paging, handover, and other procedures of the user.

Embodiments of the present invention may also utilize the identity of a third party facilitator for paging. An embodiment of the paging method is described below with reference to fig. 6.

Fig. 6 illustrates a flow diagram of a paging method according to some embodiments of the present invention. As shown in fig. 6, the paging method of this embodiment includes steps S602 to S604.

In step S602, in a case that the third-party service provider supported by the cell of the second base station and stored by the first base station includes the third-party service provider selected by the paged user, the first base station sends a paging message to the second base station, where the paging message includes an identifier of the third-party service provider selected by the paged user.

In step S604, the second base station transmits a paging message on a cell supporting the third party service provider selected by the paged user. That is, the second base station does not transmit paging messages on cells of third party providers that do not support the user's selection to be paged.

Therefore, the first base station sends the paging message under the condition that the cell of the second base station supports the identification of the paged user-selected third-party service provider, and the second base station also sends the paging message on the cell supporting the paged user-selected third-party service provider, so that the waste of network resources is avoided.

Some application scenarios of the invention are exemplarily described below.

In an exemplary scenario, a user U1 of a public network signs up with a third party service provider S1, and some private networks N1 and S1 have mutually authorized in advance, so that U1 can access N1 to use network services. The base station NB1 providing the N1 network service interacts with the NB2 in advance for the identification of the third party service provider and saves, finding that both support S1.

When U1 wants to handover from NB1 to the target cell of NB2, NB1 sends a handover request to the core network device. When the core network device finds that the target of NB2 also supports S1, it sends a handover request to NB 2.

When U1 wants to handover from NB1 to the target cell of NB2, NB1 sends a handover request to the core network device. When the core network device finds that the target of NB2 also supports S1, it sends a handover request to NB 2. However, the target cell of NB2 has been configured updated and is currently not supported by S1. The NB2 feeds back a handover failure message to the core network device after receiving the handover request. The core network and NB1 update the identity of the third party service providers supported by the cell of NB2 to avoid handing over again the user selecting S1 to that cell of NB 2.

When NB2 receives the paging request sent by NB1, finding that the paged user has selected S1, NB2 sends the paging message only on cells supporting S1.

Thus, the present invention can be applied to a variety of network service scenarios.
