Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, specific embodiments of the present disclosure are described below in detail with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order; also, the embodiments and features of the embodiments in the present disclosure may be arbitrarily combined with each other without conflict.
In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for the convenience of explanation of the present disclosure, and have no specific meaning in themselves. Thus, "module", "component" or "unit" may be used mixedly.
In order to solve the above problems, the embodiment of the present disclosure optimizes a management process of a slice Service by a dual-card terminal in a different network, and by adding a management unit, the management unit determines a slice capability that a base station where a primary card and a secondary card reside and an adjacent cell can bear, and then performs soft handover of the primary card and the secondary card according to the support capability of the primary card and the secondary card to the slice, so as to achieve flexible management of the slice Service, avoid the problem that a single SIM card cannot guarantee the requirements of a user on Quality of Service (Qos) of the slice network at a certain TA or a certain time, and improve the experience of the user in using a 5G Service.
Referring to fig. 1, fig. 1 is a flowchart illustrating a slice management method for a dual-card terminal according to an embodiment of the present disclosure, where a primary card and a secondary card of the dual-card terminal are subscriber identity cards of different operators, and the method is applied to a slice management unit, hereinafter referred to as a management unit, of the dual-card terminal, and includes steps S101 to S103.
Since the core network, the bearer network, and the wireless network of the operator to which the main and auxiliary cards of the different network belong are different, and the session request and the slice management between the two SIM cards of the terminal cannot be uniformly allocated on the network side, the slice management unit is newly added in this embodiment, and the slice management unit can be deployed on the terminal side (non-shared co-establishment scene) or on the gbb-CU (base station shared co-establishment situation) to realize management of slice switching of the double cards of the different network, so as to realize flexible allocation of the main and auxiliary cards when a user requests a slice service, and improve user experience.
In step S101, after a main card of a terminal initiates a first slicing request to a first base station and a first core network connected thereto, it is determined whether the main card can carry the requested slicing service, if the main card cannot carry the slicing service, step S102 is executed, otherwise, the process is ended, and a slicing registration process is completed by using the prior art.
Specifically, when the main card (SIM1, connected first base station gNB1) of the terminal initiates a slicing request, the terminal reports messages such as SUCI-1(Subscription shared Identifier), requested NSSAI (PLMN1) (requested Single Network slot Selection access Information) to the first core Network of gNB1, PLMN1 (first Public Land Mobile Network 1). And the management unit judges whether the main card can bear the slicing service of the slicing request.
It is understood that PLMN1 and PLMN2 correspond to different operator networks, respectively.
Specifically, the management unit determines whether the main card can carry the slicing service requested by the slicing request, and determines whether the following situations occur: a, RRM (Radio Resource Management, network element) of gbnb1 feeds back to a Management unit that current Radio resources cannot guarantee Qos corresponding to the slice (for example, congestion in a hot spot area, routing delay greater than Qos requirement of the unmanned slice, etc.); b. the AMF (Access and Mobility Management Function) selected by the terminal may allow the terminal to Access the slice of the NSSAI, but the Management unit sends a request to the core network to obtain the AMF \ SMF load and the average routing delay of the terminal connection, if the AMF \ SMF load is larger than a first preset threshold or the average routing delay exceeds a second preset threshold (for example, the terminal is in a remote area, the AMF SMF is directed to a home location with a longer distance). Nssf (Network slice selection Function) returns a registration confirmation message to the terminal: since no subscription or the current TA does not belong to the slice service area, the Requested NSSAI is rejected by the core network.
In an embodiment, for a case that the class a master card cannot carry a slicing service, the determining whether the master card can carry the slicing service requested by the slicing request includes the following steps:
receiving current radio resource information reported by a radio resource management network element of the first base station;
judging whether the current wireless resource information can guarantee the network service quality corresponding to the slicing service;
and if the network service quality corresponding to the slicing service cannot be guaranteed, judging that the main card cannot bear the slicing service requested by the slicing service.
In an embodiment, for a case that the class b master card cannot carry a slicing service, the determining whether the master card can carry the slicing service requested by the slicing request includes the following steps:
acquiring the load of a first mobile access management network element and the average routing delay of a first session management network element from the first core network;
judging whether the load of the first mobility access management network element exceeds a first preset threshold value and whether the average routing delay of the first session management network element exceeds a second preset threshold value;
and if the load of the first mobile access management network element exceeds a first preset threshold value or the average routing delay of the first session management network element exceeds a second preset threshold value, judging that the main card cannot bear the slicing service of the slicing request.
In an embodiment, for a case that the class c master card cannot carry a slicing service, the determining whether the master card can carry the slicing service requested by the slicing request includes the following steps:
acquiring a slice registration confirmation message returned to the terminal by a first network slice selection function network element from the first core network;
determining whether the first slice request is rejected by the first core network based on the slice registration confirmation message;
if the first slicing request is rejected by the first core network, it is determined that the master card cannot carry the slicing service of the slicing request.
In step S102, it is determined whether the secondary card of the terminal can bear the slicing service, if so, step S103 is executed, otherwise, the process is ended.
In this embodiment, the manner of determining whether the secondary card can carry the slice service is the same as that of determining whether the primary card can carry the slice service, for example, the RRM of the gNB1 feeds back to the management unit that the current radio resource cannot guarantee the Qos corresponding to the slice, at this time, the current radio resource of the gNB2 where the secondary card SIM2 resides is determined, if the gNB2 can guarantee the current radio resource of the slice service, it is indicated that the secondary card can carry the slice service, at this time, the management unit initiates a primary-secondary card switching notification to the terminal, thereby implementing flexible switching of the primary and secondary cards and initiation of the slice service, and improving network experience of the user.
In step S103, a primary-secondary card switching notification is initiated to the terminal, so that the terminal performs primary-secondary card switching after receiving the primary-secondary card switching notification, and the secondary card initiates a second slicing request for requesting the slicing service to a second base station and a second core network connected to the secondary card.
Specifically, if the secondary card is judged to carry a request NSSAI (PLMN2) slice, the management unit will notify the user at the upper layer: and performing automatic soft switching of the main card and the auxiliary card. If the user does not reject the request, the management unit informs the terminal of switching the main card and the auxiliary card, then the terminal switches the current auxiliary card into the main card, the management unit informs the terminal of initiating the slice registration request again in the PLMN2 network, and the request NSSAI of the terminal requesting this time sends messages such as SUCI-2\ request NSSAI (PLMN2) and the like to the network of the PLMN 2. Further, at this time, the terminal side also needs to perform a relational mapping process on the URSP slice routing rule, and the parameters in the SIM card 1URSP rule are: APP ID/DNN/SSC MODE is correspondingly mapped to URSP rule parameters of the SIM card 2, and slice management at the terminal side is realized.
Referring to fig. 2, fig. 2 is a flowchart illustrating a slice management method for a dual-card terminal according to a second embodiment of the present disclosure, where on the basis of the first embodiment, the loading conditions of the primary and secondary cards for a slice service are considered, and compared with the first embodiment, the present embodiment further includes a step S201, the step S101 is further divided into a step S101a, and the step S102 is further divided into a step S102 a.
In step S201, slice connection records of the first base station and its neighboring cells and slice connection records of the second base station and its neighboring cells are obtained.
Specifically, the management unit acquires the NSSAI number which is transmitted by the base station and has been connected recently, and the NSSAI numbers which are connected by all cells adjacent to the current cell, so that the management unit will obtain the slice service which can be provided by the gNB where the primary card and the secondary card are located, and the slices which can be provided by the adjacent cells gNB, and the newly added management unit will also collect the carrier frequencies of the adjacent cells of the gNB1, the gNB2, the gNB1 and the gNB2 for cell reselection.
In step S101a, it is determined whether the first base station and its neighboring cell have connected the slicing service based on the slicing connection records of the first base station and its neighboring cell, respectively, and if the first base station and its neighboring cell have not connected the slicing service, it is determined that the main card cannot carry the slicing service.
Further, if the first base station does not connect the slice service and belongs to any of the above situations that the slice service cannot be carried, but the neighboring cell gNB3 is connected to the slice service once and can carry the slice service, the terminal is instructed not to perform cell reselection, specifically, the terminal is issued a priority for updating a cell reselection rule, for example, the priority of the gNB3 is increased and the gsb 3 cell carrier frequency collected by the management unit is sent to the terminal, the terminal searches the cell according to the gsb 3 cell carrier frequency and performs base station signal measurement on the cell, if the cell measurement rsrp reselection rsrq/sinr result meets the threshold requirement, the cell handover is completed, and the registration process of a requested NSSAI (PLMN1) slice is continuously performed through the gsb 3.
When the management unit is arranged at the terminal side, the management unit judges whether the current gNB1 and gNB2 numbers of the terminal are changed or not and cell switching occurs, if the numbers are changed, the management unit sends a request to the gNB with the changed numbers and requests the gNB to send the NSSAI number which is connected recently and the NSSAI numbers which are connected with all cells adjacent to the current cell to the management unit. Thus, the management unit can obtain the slice service provided by the gNB where the main card and the auxiliary card are located, and the slices provided by the adjacent gNB. The management unit will also collect carrier frequencies of the gNB1, gNB2 and gNB1 and gNB2 neighboring cells for cell reselection.
It should be noted that, when the cell reselection step is performed on the terminal side with respect to the management Unit, in some embodiments, the management Unit may also be disposed on the shared co-established base station side, for example, wireless resources of different PLMN networks to which the primary card and the secondary card belong are deployed on the same base station, at this time, terminal domain splitting is performed by broadcasting different PLMNs, the management Unit may be disposed on a CU (Centralized Unit) of the shared base station gNB for deployment, the management Unit notifies the terminal of the cell reselection message through an SIB broadcast message, and issues the cell reselection message of the cell reselection priority, the carrier frequency, and other messages from the base station side to the terminal, without collecting information such as the carrier frequency of the neighboring cell in advance and then sending the information to the terminal.
In step S102a, it is determined whether the second base station and its neighboring cell have connected the slice service based on the slice connection records of the second base station and its neighboring cell, respectively, and if the second base station or its neighboring cell have connected the slice service, it is determined that the secondary card can carry the slice service.
It should be noted that the bearer slice service in this embodiment takes into account the c-type scenario, and in some embodiments, the a-type scenario and the b-type scenario may be combined as optimization.
Specifically, first, it is determined whether the second base station has connected the slicing service, and if the second base station has connected the slicing service, the second base station can carry the slicing service, and at this time, the slicing network service quality, AMF \ SMF load, and average route delay may be further analyzed based on the foregoing manner in the foregoing embodiment, and when the network service quality does not meet the requirement, and the load exceeds a first preset threshold or the average route delay exceeds a second preset threshold (the cases of types a and b described above), it is further determined whether the adjacent cell of the second base station has connected the slicing service, and then information such as the network service quality and the load is determined, so as to select a better base station to complete cell handover and further implement the slicing service.
Referring to fig. 3, fig. 3 is a slice management method for a dual-card terminal according to a third embodiment of the present disclosure, and on the basis of the first embodiment, the method further includes step S301 and step S302, the step S101 is further divided into step S101b, and the step S102 is further divided into step S102b and step S102 c.
In step S301, a first slice number of the slice service under the operator to which the main card belongs and a second slice number of the slice service under the operator to which the auxiliary card belongs are obtained;
in step S302, a mapping relationship list of the slice service under the operators to which the primary card and the secondary card belong is established based on the first slice number and the second slice number.
Specifically, the CU control module of each gNB will record the NSSAI slice numbers to which it has been connected. The management unit stores a mapping relation list of the operator to which the primary and secondary SIM cards belong to the slice NSSAI: for example, in PLMN1, NSSAI1 corresponds to NSSAI9 in PLMN 2.
In step S101b, it is determined whether the master card can carry the slice service requested by the slice based on the first slice number.
Specifically, whether the main card can carry the slice service is quickly judged by judging whether the main card residing base station is connected with the first slice number.
In step S102b, a second slice number corresponding to the first slice number is searched for based on the mapping relationship list; and the number of the first and second groups,
in step S102c, it is determined whether the secondary card of the terminal can carry the slice service based on the second slice number.
Specifically, if three types a, b, and c of situations that the primary card cannot carry the slicing service occur, and the cell residing in the primary card fails to be switched with the neighboring cell or a and b occur after the switching occurs, the management unit obtains a second slice number request NSSAI (PLMN2) corresponding to the secondary card according to the first slice number request NSSAI (PLMN1) of the primary card and the slice NSSAI mapping relationship list of the primary card and the secondary card, then determines to obtain a gNB2 where the current secondary card resides and an NSSAI that can be carried by or connected to the neighboring cell, and then may determine whether the secondary card gNB2 and the neighboring cell can use the request NSSAI (PLMN2) slice based on the above-mentioned manner, and if it determines that the secondary card can carry the request NSSAI (PLMN2) slice, the management unit notifies the user by an upper application: and performing automatic soft switching of the main card and the auxiliary card. If the user does not reject the request, the management unit informs the terminal to switch between the main card and the auxiliary card. After the secondary card SIM2 becomes the primary card, the management unit will inform the terminal to initiate the slice registration request again in the PLMN2 network. The request NSSAI requested by the terminal at this time sends SUCI-2\ request NSSAI (PLMN2) and other messages to the network of the PLMN 2.
Further, if the above a/b type situation occurs during the slicing request in Gnb2, that is, Gnb2 can connect the slicing service, but the Qos effect is not good, the management unit may perform a neighboring cell handover procedure, that is, the management unit searches neighboring cells in the Gnb2 cell, determines whether a connection record of request NSSAI (PLMN2) exists, and performs cell handover if the connection record exists, which may specifically refer to the above embodiments.
Based on the same technical concept, a fourth corresponding embodiment of the present disclosure further provides a slice management unit of a dual-card terminal, as shown in fig. 4, where the slice management unit includes:
