Description

Sharing method and device of operator network and core network equipment

[ technical field ] A method for producing a semiconductor device

The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for sharing an operator network, and a core network device.

[ background of the invention ]

With the continuous development of communication technology, each operator deploys a plurality of networks from 2G to 4G, and manages and operates the devices belonging to the own network independently to provide services for the own user, and currently, each mobile phone card only supports the network of one communication operator.

Each operator generally stores Home Public Land Mobile Network (HPLMN) and Forbidden Public Land Mobile Network (FPLMN) information in a Subscriber Identity Module (SIM) card or a Universal Subscriber Identity Module (USIM) card.

Once a Public Land Mobile Network (PLMN) of an operator is written in an FPLMN area of a SIM card or USIM card, a User Equipment (UE) does not attempt to access the PLMN during Network searching, so as to reduce the time for the UE to register in the Network. In order to access the network, the UE must match the PLMN information in the SIM card with the PLMN of the operator network and complete the registration of the network through authentication and identification, but each operator limits the information of the HPLMN and the FPLMN and cannot be used among operators.

In the prior art, PLMNs of different operators are different, and an HPLMN of a certain user is unique, so that the user can only use a network of one operator and cannot use service across operators. Thus, after the dual-network convergence is opened, a user of one operator cannot access to a network of another operator, thereby causing large-scale loss of the user.

[ detailed description ] embodiments

For better understanding of the technical solutions of the present application, the following detailed descriptions of the embodiments of the present application are provided with reference to the accompanying drawings.

It should be understood that the embodiments described are only a few embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The terminology used in the embodiments of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the examples of this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

In the prior art, because the information of PLMNs and mobile phone cards of different operators is different, the home PLMN allocated by the operator for the terminal user is stored in the SIM card, and for a certain user, the home PLMN of the user is unique, so that the user can only use the network of one operator, and cannot use the service across operators. In the process of dual-network convergence, the FPLMN list in the original SIM or USIM card is not cleared, and after the dual-network convergence is opened, a user of one operator cannot access the network of the other operator, so that the large-scale loss of the user is caused.

The application provides a sharing method of an operator network, which can clear FPLMN under the condition of network sharing, and according to a third Generation Partnership Project (3rd Generation Partnership Project, 3GPP) protocol, the FPLMN area of one SIM card or USIM card can only be written into N FPLMNs at most, so that the FPLMN can be cleared by establishing a virtual cell to be matched with a core network, and the sharing of different operator networks is realized under the condition of not influencing the existing network users.

The definition of FPLMN in the 3GPP protocol is as follows: if the network rejects location updates with a reason for "not allowing PLMNs", the PLMN is written to the base file. The Mobile Equipment (Mobile Equipment; hereinafter abbreviated ME) should manage the list as follows:

when n FPLMNs are maintained in the base file and the ME receives a rejection of another PLMN from the network, the ME will modify the base file using an UPDATE (UPDATE) command, store the new PLMN in the nth location and the existing list "shifted" resulting in the loss of previous content in the first location. When there are fewer than n FPLMNs in the base file, the storage of additional FPLMNs should not result in the loss of any existing FPLMNs.

Fig. 1 is a flowchart of an embodiment of a sharing method for an operator network according to the present application, and as shown in fig. 1, the sharing method for the operator network may include:

step 101, create a backup PLMN list.

Step 102, a virtual cell is created on an RRU of a first operator network, a frequency point of the virtual cell is a frequency point of a second operator network in an area where the first operator network is located, and a PLMN broadcasted by the virtual cell is a PLMN network number in the standby PLMN list.

In this embodiment, the number of virtual cells created on the RRU of the first operator network is the same as the number of original cells on the RRU of the first operator network, the virtual cell is configured with one carrier frequency, and the minimum access level of the virtual cell is a predetermined level.

The predetermined level may be set according to system performance and/or implementation requirements during specific implementation, and the size of the predetermined level is not limited in this embodiment, for example, the size of the predetermined level may be 0.

Taking a first operator as an operator a and a second operator as an operator B as an example, the so-called virtual cells refer to cells with the same number as that of original cells created on an RRU of an operator a network, frequency points of the virtual cells are frequency points of the operator B network, and a broadcasted PLMN is not an HPLMN of the operator a network but a PLMN network number in a standby PLMN list, so that a user of the operator B can access the cells, and the HPLMN network number of the operator a in an SIM card of a user of the operator B is squeezed. Each virtual cell is configured with one carrier frequency, so that a user can access the virtual cell, and in order to facilitate access of more users, the minimum access level (rxLevAccessMin) of the virtual cell can be set to be 0.

Step 103, adding the PLMN network number in the standby PLMN list to the virtual cell until all the PLMN network numbers prohibited from accessing in the subscriber identity module card of the second operator subscriber are cleared.

The SIM card may be an SIM card or a USIM card, which is not limited in this embodiment.

Assuming that there are at most X different PLMN network numbers in the SIM card FPLMN list of the operator B user, adding the network number in the standby PLMN list in the virtual cell, and operating X times, i.e. clearing the network numbers of all the FPLMNs in the SIM card of the operator B user.

And 104, deleting the virtual cell.

Specifically, after step 103, the core network device may delete the virtual cells in sequence.

In the sharing method of the operator network, after the backup PLMN list is created, a virtual cell is created on the RRU of the first operator network, and then the PLMN network number in the backup PLMN list is added to the virtual cell until all the PLMN network numbers prohibited from being accessed in the user identification module card of the second operator user are cleared, so that the backup PLMN list is created, and the virtual cell is created on the RRU of the first operator network, and all the PLMN network numbers prohibited from being accessed in the user identification module card of the second operator user are cleared.

Fig. 2 is a flowchart of another embodiment of a sharing method of an operator network according to the present application, as shown in fig. 2, in the embodiment shown in fig. 1 of the present application, step 101 may include:

step 201, creating a standby PLMN list according to a PLMN list of an area where the first operator network is located, where the number of PLMNs included in the standby PLMN list is greater than or equal to the number of PLMNs used by all operators in the area where the first operator network is located.

For example, if the number of PLMNs used by all operators in the area where the first operator network is located is 8, 8 PLMN network numbers need to be created in the standby PLMN list.

Fig. 3 is a flowchart of a further embodiment of a sharing method for an operator network according to the present application, as shown in fig. 3, in the embodiment shown in fig. 1 of the present application, step 103 may include:

step 301, setting the network rejection reason of the home PLMN network number of the first operator network as that no suitable cell for access exists in the area where the first operator network is located.

Step 302, under the first operator network, sequentially configuring PLMN network numbers in the standby PLMN list on the virtual cell, and blocking the second operator network, so that the UE used by the second operator user sequentially attempts to update the location area under the newly configured PLMN network number, and after receiving the reject reason that the newly configured network number does not allow access, sequentially writing the newly configured PLMN network number into the PLMN area prohibited from being accessed by the user identity module card in the UE, until all PLMN network numbers prohibited from being accessed in the user identity module card of the second operator user are cleared.

Still taking the first operator as operator a and the second operator as operator B as an example, assuming that at most X different PLMN network numbers exist in the SIM card FPLMN list of the operator B user, clearing the PLMN network numbers in the SIM card FPLMN list of the operator B user may include:

step A, setting a network rejection reason of the HPLMN network number of an operator A to be a reason value 15 through core network side equipment of an operator B, wherein a cell (Cause 15 #: No Suitable Cells In Location Area) Suitable for access does not exist In an Area where the network of the operator A is located, and the PLMN is not allowed to access any more (PLMN not allowed);

step B, under an operator A network, based on the current network cell, adding virtual cells with the same number as the original cells on RRU of the operator A network, adding 1 carrier frequency to each virtual cell, sequentially configuring PLMN network numbers in a standby PLMN list on the newly added virtual cells, blocking the operator B network, enabling UE (user equipment) used by a user of the operator B to try to update a location area under the newly configured PLMN network number, and writing the newly configured PLMN network number into a PLMN forbidden area of a user identity module card in the UE after receiving a rejection reason that the newly configured network number does not allow access (PLMN not allowed);

step C, after trying for X times, removing the HPLMN of the operator A network from the PLMN area which is forbidden to be accessed in the user identity module card of the operator B user, so that the operator B user can be accessed into the operator A network after the network sharing function is opened;

and D, performing FPLMN clearing operation again in the areas of the operator A network and the operator B network in the subsequent dual-network convergence opening process.

The operator a and the operator B need to perform network sharing, and need to perform cleaning of the FPLMN. The implementation scheme is as follows:

(1) creating a standby PLMN;

the FPLMNs of operator a and operator B are both 3, so the network numbers in the backup PLMN list can be set to 40011, 40012, and 40013.

(2) A virtual cell is created.

Virtual cells with the same number as the original cells are established on the original RRU of an operator A, each virtual cell is provided with 1 carrier, and the minimum access level of the virtual cell is set to be 0, so that the user can conveniently access the RRU.

(3) The FPLMN is cleared.

In order to access the operator a network by the user of the operator B, the network rejection reason of the HPLMN network number of the operator a may be set to "Cause value 15 — there is No Suitable cell (Cause 15 #: No successful cell In Location Area)" In the Area where the operator a network is located, the operator B network is blocked, the PLMN 40011 is configured on the virtual cell, the UE used by the operator B user tries to update the Location Area under the new PLMN 40011, after the UE receives the rejection reason of not allowing access (PLMN not allowed), the new PLMN 40011 is written into the FPLMN Area of the SIM card In the UE used by the operator B user, and the original network number In the FPLMN Area is flushed;

and sequentially configuring the PLMN 40012 and the PLMN 40013 on the virtual cell, and repeating the process, so that the network numbers in the FPLMN area of the SIM card in the UE used by the operator B user become 40011, 40012 and 40013. The 40001 in the SIM card of the operator B user is the available HPLMN, and the operator B user can access the operator a network.

(4) And deleting the virtual cell and ending the process.
