Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor terminal devices and/or microcontroller terminal devices.
The technical scheme of the embodiment of the present disclosure can be applied to various communication systems, for example: a global system for mobile communications (GSM) system, a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) system, a General Packet Radio Service (GPRS), a Long Term Evolution (LTE) system, a LTE frequency division duplex (frequency division duplex, FDD) system, a LTE Time Division Duplex (TDD), a universal mobile telecommunications system (universal mobile telecommunications system, UMTS), a Worldwide Interoperability for Microwave Access (WiMAX) communication system, and a fifth generation (5G) or New Radio (NR) system.
The technical scheme of the embodiment of the disclosure can be applied to a core network roaming scene.
The core network roaming refers to that one operator (i.e. carrier operator) independently establishes a complete set of 5G network (including a wireless network and a core network), and users of other operators (i.e. sharing carrier operators) can access the network and use mobile communication services. The technical method is suitable for 2/3/4/5G network signals that a sharing party has an operator without attribution in a relevant area. In terms of service implementation, in a roaming responsibility area, an contractor operator (also called a roaming service operator) opens services such as 5G voice, data and short messages to other operator users by increasing new network numbers of other operators, and ensures communication quality. The routing mode can be the intercommunication of the home network and the 5G core network of the roaming network, the authentication registration can be carried out by returning to the home network based on the IMSI number segment, and the home network is responsible for the work of voice connection, Internet access, short message processing and the like.
Hereinafter, the steps of the method for implementing network access in the exemplary embodiment of the present disclosure will be described in more detail with reference to the drawings and the embodiment.
Fig. 1 is a flow chart illustrating a method for implementing network access according to an exemplary embodiment. The method provided by the embodiment of the present disclosure may be performed by a core network device of a roaming service operator, but the present disclosure is not limited thereto.
In the embodiment of the present disclosure, the roaming service operator may be a carrier for building a 5G network.
As shown in fig. 1, a method for implementing network access provided by the embodiment of the present disclosure may include the following steps.
In step S102, an access request of the ue is obtained, where the access request includes a radio network number selected by the ue.
In the embodiment of the present disclosure, before the ue accesses, the base station may broadcast the first wireless network number of the first operator, the second wireless network number of the second operator, and the third wireless network number or the fourth wireless network number of the roaming service operator.
The third wireless network number of the roaming service operator may be a new network number, and the fourth wireless network number of the roaming service operator may be an old network number.
That is to say, in the embodiment of the present disclosure, the base station needs to broadcast a new network number of another sharing party operator in addition to the wireless network number of the roaming service operator, and each sharing party operator corresponds to one new network number.
In the following description, the roaming service operator (or carrier operator) is the operator C, the third wireless network number is C, the fourth wireless network number is C', the first operator is the operator a, the first wireless network number is a, the second operator is the operator B, and the second wireless network number is B, which are all taken as examples, but the disclosure is not limited thereto.
For example, operator C is responsible for building a 5G base station in a core network roaming area, the operator C provides roaming service for operator a and operator B, and the 5G base station in the area broadcasts a new network number a of operator a and a new network number B of operator B; operator C may broadcast a new Network number C, or a previously assigned old Network number C', written in a Forbidden PLMN (Public Land Mobile Network) list in the SIM (Subscriber identity Module) cards of the terminals corresponding to operator a and operator B, to which the users of operators a and B do not attempt to access.
In the embodiment of the present disclosure, in a case that the base station broadcasts the first access network number, the second access network number, and the third wireless network number, the user equipment may randomly select one of the first access network number, the second access network number, and the third wireless network number for access.
In the embodiment of the present disclosure, when the base station broadcasts the first access network number, the second access network number, and the fourth wireless network number, since the fourth wireless network number is in the forbidden list of the user equipment, the user equipment does not select the fourth wireless network number, and the user equipment can randomly select one of the first access network number and the second access network number for access.
Taking the operator a as an example, the operator a has no other mobile network signals in the above area, and when the 5G user equipment of the operator a is turned on in the area for the first time, the PLMN a, b, c or c' can be searched at the same time. In case of broadcasting PLMNs a, b, c, the user may randomly select PLMN a, b or c for access; in case of broadcasting the PLMNs a, b, c', the user may randomly select the network number PLMN a or b for access.
In the embodiment of the present disclosure, after the user equipment randomly selects one wireless network number, the core network device of the operator C may obtain an access request of the user equipment, where the access request includes the wireless network number selected by the user equipment.
In an exemplary embodiment, the core network device may include an AMF (Access and Mobility Management Function, Access and Mobility Management network element).
In the following, the core network device is taken as an AMF as an example for explanation, but the present disclosure is not limited thereto.
For example, the user equipment selects the wireless network number b, and initiates an initial registration request, where the registration request carries the wireless network number b accessed by the terminal equipment.
In step S104, a target operator corresponding to the wireless network number selected by the user equipment is determined.
In this embodiment of the present disclosure, the AMF of the operator C may determine a target operator corresponding to the wireless network number selected by the user equipment.
For example, if the wireless network number selected by the user equipment is a, it may be determined that the target operator is operator a; for another example, if the number of the wireless network selected by the user equipment is B, it may be determined that the target operator is operator B.
In step S106, if the home operator and the target operator of the user equipment are not consistent, the access request is rejected.
In the embodiment of the present disclosure, the AMF of the operator C may determine whether the home operator (i.e., the actual operator) of the user equipment is consistent with the target operator (i.e., the operator selected by the user for access), and reject the access request if the home operator of the user equipment is inconsistent with the target operator; if the home operator of the user equipment is consistent with the target operator, the access request of the user equipment is sent to core network equipment corresponding to the target operator (namely, the home operator) so as to complete the access of the user equipment.
In the embodiment of the present disclosure, determining whether the home operator of the user equipment is consistent with the target operator may be performed by determining whether the user identifier of the user equipment belongs to the target operator.
If the user identification code of the user equipment does not belong to the target operator, the access request is refused; if the identification code of the user equipment belongs to the target operator, the access request of the user equipment is sent to a UDM/AUSF (Unified Data Management, Unified Data Management Web page/Authentication Server Function, Authentication service network element) of the home operator so as to complete the access of the user equipment.
The identifier of the ue may be an IMSI (International Mobile Subscriber Identity).
For example, the AMF of the operator C (which may also be referred to as a visited AMF) performs a comparison check on the network number selected by the user and the IMSI thereof, and if the IMSI thereof is found not to belong to the operator corresponding to the selected network number, the user is denied access; if the visiting AMF verifies that the IMSI belongs to the operator corresponding to the selected Network number, the user is allowed to access, NRF (Network security function) is inquired according to a normal flow, and the message is routed back to the home Network, so that initial registration is completed, and the user can normally use the service.
In the embodiment of the present disclosure, after the AMF of the operator C rejects the access request of the user equipment, an access rejection response may be returned to the user equipment.
The reject access response may carry a reject reason, and the reject may be, for example, a reason value #11(PLMN not allowed).
In the embodiment of the disclosure, after receiving the response of denying access, the user equipment may reselect another wireless network number for re-access.
In the embodiment of the present disclosure, the AMF of the operator C may receive a re-access request returned by the ue in response to the response refusing to access, where the re-access request includes a radio network number reselected by the ue; and determining a target operator corresponding to the radio network number reselected by the user equipment.
In the embodiment of the disclosure, the AMF of the operator C may re-determine whether the home operator and the target operator of the user equipment are consistent, and if the home operator and the target operator of the user equipment are not consistent, reject the access request; and if the home operator of the user equipment is consistent with the target operator, sending the access request of the user equipment to core network equipment corresponding to the target operator so as to complete the access of the user equipment.
In the embodiment of the present disclosure, in a case that the base station broadcasts the first access network number, the second access network number, and the third wireless network number, the user equipment randomly selects one from the first access network number, the second access network number, and the third wireless network number to access, and if the user equipment is denied to access, the user equipment selects one from the first access network number, the second access network number, and the third wireless network number that is different from the wireless network number selected last time to access.
For example, under the condition of broadcasting the PLMNs a, b, and C, the user equipment of the operator a randomly selects the wireless network number b for access for the first time, the AMF of the operator C determines that the home operator of the user equipment is inconsistent with the target operator corresponding to the wireless network number selected by the user equipment, and the AMF of the operator C rejects the access request of the user equipment; if the user equipment of the operator A reselects the wireless network number C for access, the AMF of the operator C judges that the home operator of the user equipment is inconsistent with the target operator corresponding to the wireless network number selected by the user equipment, and refuses the access request of the user equipment again; and if the user equipment of the operator A reselects the wireless network number a for access, and the AMF of the operator C judges that the home operator of the user equipment is consistent with the target operator corresponding to the wireless network number selected by the user equipment, the user equipment is allowed to access.
In the embodiment of the present disclosure, when the base station broadcasts the first access network number, the second access network number, and the fourth wireless network number, since the fourth wireless network number is in the forbidden list of the user equipment, the user equipment does not select the fourth wireless network number, the user equipment may randomly select one from the first access signal and the second access signal to access, and if the user is denied access, the user equipment selects a wireless network number different from the wireless network number selected last time to access.
For example, under the condition of broadcasting the PLMNs a, b, and C, the user equipment of the operator a randomly selects the wireless network number b for access for the first time, the AMF of the operator C determines that the home operator of the user equipment is inconsistent with the target operator corresponding to the wireless network number selected by the user equipment, and the AMF of the operator C rejects the access request of the user equipment; and if the user equipment of the operator A reselects the wireless network number a for access, and the AMF of the operator C judges that the home operator of the user equipment is consistent with the target operator corresponding to the wireless network number selected by the user equipment, the user equipment is allowed to access.
In the method for implementing network access provided by the embodiment of the present disclosure, the core network device of the roaming service operator may determine the target operator corresponding to the core network device according to the wireless network number selected by the user device, determine whether the target operator and the home operator of the user device are consistent, and if not, reject the access request; the method can ensure that the user equipment is accessed to the home operator to which the user equipment belongs, can track the end-to-end signaling of the user, and avoids the problems of charging error and incapability of tracking the end-to-end signaling caused by access error. In addition, the core network equipment can return an access rejection response to the user equipment, and the user equipment can reselect the wireless network number and continue to access after receiving the access rejection response, so that the success rate of correct access of the user equipment is improved.
Fig. 2 is a diagram illustrating a method for guiding a user to select a correct new network number to access a network according to an example.
Referring to fig. 2, in S1, when the user equipment UE of operator a is first powered on in the shared area, it may randomly select a radio network number (e.g., select radio network number b) for access, and send a registration request message to the AMF; in S2, when the user accesses, the AMF checks the IMSI number segment of the user and the network number selected for the user, and if the IMSI number segment does not match the network number selected for the user, the AMF denies the user access; in S3, the AMF returns a reject access response to the UE; the UE may reselect the wireless network number (e.g., select wireless network number a), the AMF checks the IMSI number segment of the user and the network number selected by the user again, and after verifying that the correspondence is satisfied, in S4, routes the signaling message of the user to the home network (UDM/AUSF of operator a) for authentication according to the number segment.

The following describes a method for implementing network access according to the embodiment of the present disclosure, taking a roaming service operator as an a-operator as an example.
For example, the first operator is responsible for the construction of a 5G base station in a certain area where a core network roams, and provides roaming services for the second operator and the third operator, and the 5G base station in the area may broadcast a new network number 46088 of the second operator and a new network number 46089 of the third operator; and the new network number 46090 of operator a. The third operator has no other mobile network signals in the area, when the 5G user of the third operator is first powered on in the area, the network numbers 46088, 46089 and 46090 can be searched at the same time, and without the guidance of the home network, the user will treat the three new network numbers equally (the network numbers are not written in any PLMN list in the SIM card), and randomly select one of the new network numbers for access. Assuming that the user randomly selects 46088 to access, the user equipment initiates initial registration, the message carries the accessed wireless network number 46008, the V-AMF of the first operator checks the network number 46088 selected by the user and the IMSI thereof, finds that the IMSI does not belong to the operator b corresponding to the selected network number 46088, denies the user access, and rejects a cause value #11(PLMN not allowed) carried in a response message to registration rejection, after receiving the rejection message, the user reselects another new network number 46089 to re-access, and verifies that the IMSI belongs to the operator c corresponding to the selected network number 46089, the V-AMF allows the user to access, queries NRF according to a normal flow, and routes the message back to the home network, thereby completing the initial registration, and the user can normally use the service.
