Description

Forbidden list processing method and device, storage medium, terminal and base station
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for processing a forbidden list, a storage medium, a terminal, and a base station.
Background
Based on the existing communication technology, after a User Equipment (User Equipment, abbreviated UE) attempts to access a Public Land Mobile Network (PLMN) and is rejected, the PLMN is added into a list, and the User Equipment does not attempt to access PLMNs (i.e. s PLMNs, where s is greater than or equal to 1) recorded in the list in a subsequent registration attempt, and the list may be referred to as a Forbidden PLMN list (FPLMN list). Similar lists are also arranged in registration areas (including location areas, routing areas, tracking areas, etc.). These lists are collectively referred to as forbidden lists according to the latest protocol of the third Generation Partnership Project (3rd Generation Partnership Project, 3GPP), which is advantageous for improving the registration efficiency of the user equipment. However, in practical applications, these forbidden lists have many disadvantages, such as increased power consumption and signaling overhead of the ue.
Taking the FPLMN list as an example, based on the existing scheme, the user equipment can delete the FPLMN list only at a specific time, and after deleting the FPLMN list, the user equipment performs an action of searching for a PLMN, which is very power consuming. The specific time may be when a timer (a timer configured specifically for the FPLMN list, such as a T3245 timer) expires or when a specific event occurs (for example, some user equipments may not configure the T3245 timer, and may only use the specific event specified by the existing protocol as a trigger condition for triggering a deletion action of deleting the FPLMN list).
However, these specific times are predetermined based on the protocol, and in practical applications, in most cases, the signal quality of the PLMN where the user equipment is located may be very good when the specific time comes, and it is not necessary to delete the FPLMN list to search for a PLMN again. If the existing scheme is still used, the search action is forcibly triggered when the ue does not actually need to search the PLMN, which may greatly waste the power consumption of the ue and is not favorable for saving the power consumption of the ue (also referred to as power consumption).

Detailed Description
As will be appreciated by those skilled in the art, as mentioned in the background, the existing processing logic for the forbidden list is still limited to a specific time preset by the protocol as a trigger condition, and the forbidden list can be processed by the user equipment only when the specific time comes.
Taking Forbidden PLMN Lists (FPLMN Lists for short) as an example, based on the existing scheme, for a ue configured with a T3245 timer (a timer configured specifically for FPLMN Lists), the FPLMN list can be deleted only when the T3245 timer expires.
For example, referring to fig. 1, the user equipment 1 configures the T3245 timer, and when the registration attempt for a PLMN in the network 2 fails (e.g. receives any reason related to forbidden PLMN sent by the network 2 (e.g. attach reject, tracking area update reject, service reject, etc.)), the user equipment 1 performs action s1 to add the PLMN attempting access this time to the appropriate FPLMN list; and the user equipment 1 further performs action s2 to activate the T3245 timer. When the T3245 timer expires (which may also be referred to as expired), the user equipment 1 performs action s3 to delete all PLMNs recorded in the FPLMN list; and the user equipment 1 also performs action s4 to start the cell selection procedure.
However, in practical applications, the time set by the T3245 timer may be long (for example, the time set by the T3245 timer may be as long as 24 hours), and if the network wishes to delete the FPLMN list during this period, so that the ue may search all PLMNs (for example, the network considers that the signal quality of the PLMN where the ue is currently located is poor, and needs to perform PLMN search again), the existing scheme cannot meet this requirement of the network. Even if the signal quality of the PLMN where the ue is located is very good when the T3245 timer expires, and the ue does not need to delete the FPLMN list to search for the PLMN again, based on the prior art, the ue must delete the FPLMN list and search for the PLMN again when the T3245 timer expires, which certainly causes a great waste in power consumption and power consumption of the ue.
Alternatively, in some cases, some user equipments may not configure the T3245 timer, for example, referring to fig. 2, the user equipment 1 does not configure the T3245 timer, and when the registration attempt for a PLMN in the network 2 fails (e.g. when any reason related to the forbidden PLMN sent by the network 2 is received (e.g. attach reject, tracking area update reject, service reject, etc.), the user equipment 1 performs action s1 to add the PLMN attempting access to the appropriate FPLMN list. However, unlike the scenario described in fig. 1, since the user equipment 1 is not configured with the T3245 timer in this scenario, the FPLMN list is not erased after a period of time. Further, in this scenario, the ue 1 can only perform the action of deleting the FPLMN list based on some specific events (determined based on the existing protocol, for example, when a Universal Subscriber Identity Module (USIM) changes), and if the specific events do not occur, the network 2 also wants to delete the FPLMN list, the prior art also fails to meet the requirement of the network.
On the other hand, in practical applications, after the FPLMN list is deleted, the ue needs to perform an action of searching for a PLMN again, which is very power consuming, and based on the prior art, if the T3245 timer expires or a specific event occurs, the ue does not need to search for a PLMN but searches for the PLMN actually, which wastes power of the ue greatly and is not favorable for saving power consumption.
In summary, the existing solution may cause the problem that the FPLMN list of the ue is forcibly deleted when it is not needed to be deleted, but cannot be deleted when it is needed to be deleted, so that for the ue, if the solution in the prior art is still used to process the forbidden list, it will inevitably cause a great signaling overhead and power consumption.
The inventor has analyzed and found that the problem of the prior art is that the processing logic for the forbidden list is not flexible enough to effectively reduce the signaling overhead and the power consumption of the user equipment.
In order to solve the technical problem, the technical scheme of the embodiment of the invention receives indication information sent by a network; deleting at least a portion of the content recorded in the forbidden list based on the indication information. Those skilled in the art understand that the technical solution of the embodiment of the present invention allows the user equipment to process the forbidden list more flexibly, for example, whether to trigger a deletion operation of the forbidden list may be determined according to an indication of the network, so as to optimize signaling overhead. Further, different from the prior art, the technical solution of the embodiment of the present invention also allows the user equipment to process only a part of the contents in the forbidden list, thereby effectively reducing the power consumption (or power consumption) of the user equipment.
Further, the indication information may be sent through a message or data, so as to better save signaling overhead. For example, the message may include Access Stratum (AS) signaling, non-Access Stratum (NAS) signaling, a message dedicated to indicating deletion of the forbidden list; as another example, the data may include data transmitted based on an application layer.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Fig. 3 is a flowchart of a forbidden list processing method according to a first embodiment of the present invention. The forbidden list may be a list (also referred to as a set) of networks to which access is prohibited in a process of interaction between User Equipment (User Equipment, abbreviated as UE) and the networks; the network may include at least one sub-network, each sub-network may serve user equipment in its signal coverage area, the signal coverage areas of a plurality of sub-networks (e.g., adjacent sub-networks) may have an overlapping area, and the user equipment in the overlapping area may select one sub-network from the plurality of sub-networks for information interaction; for the user equipment side, when the user equipment attempts to access a sub-network but is rejected (i.e. registration in the sub-network fails), the user equipment may add the sub-network to a forbidden list stored locally in the user equipment, and in the following registration attempt, the user equipment will not attempt to register to the sub-network recorded in the forbidden list.
Therefore, the forbidden list may be a list of prohibited access subnets. Taking a Public Land Mobile Network (PLMN) as an example, the Network may include s PLMNs (s ≧ 1), and the forbidden list may include a list of PLMNs to which access is forbidden (forbidden PLMNs).
Further, the list of PLMNs to which access is prohibited may include a forbidden PLMN list (forbidden PLMN list), a list of forbidden PLMNs to be attached in the S101 mode, a list of forbidden PLMNs to be used in a General Packet Radio Service (GPRS), and the like.
It should be noted that, although the embodiment specifically explains the forbidden PLMN list (hereinafter, abbreviated as FPLMN list) in the forbidden PLMN list as an example, this does not mean that the technical solution of the embodiment of the present invention is only applicable to the forbidden PLMN list, and the technical solution of the embodiment of the present invention can also be applied to other forbidden PLMNs besides the forbidden PLMN list, for example, a forbidden PLMN list based on a registration area, a location area, a routing area, a tracking area, and the like.
Specifically, in this embodiment, the method for processing the forbidden list may be implemented as follows:
step S101, receiving indication information sent by a network.
Step S102, based on the indication information, deleting at least a part of the content recorded in the forbidden list.
Further, the indication information is used to instruct the user equipment to delete at least a part of the content (e.g., at least a part of the PLMN) recorded in the forbidden list (e.g., FPLMN list) associated therewith.
Further, the indication information may be transmitted through a message.
In a preferred example, the message (also referred to AS signaling) may include an Access Stratum (AS) message, a non-Access Stratum (NAS) message, and other existing messages. For example, the network may place the indication information in a reserved bit of an access stratum message sent to the ue, and the ue may obtain the indication information from the reserved bit according to a pre-agreement with the network after receiving the access stratum message (e.g., the network may pre-agree with the ue about a placement position and a placement manner of the indication information). Preferably, the access stratum message or the non-access stratum message may include a paging indication (paging indication), a direct indication (direct indication), a Tracking Area Update (Tracking Area Update, TAU for short), an Attach (Attach), and the like, and those skilled in the art may also change further embodiments according to actual needs, which is not described herein.
As a variant, the message may also comprise a new message dedicated to indicating deletion of the forbidden list, wherein the new message may be sent by the network to the user equipment separately.
Further, the indication information may also be transmitted through data. In a preferred example, the data may include data transmitted based on an application level (application level). For example, the network may add the indication information in data sent to an application layer, which is routed to a modem of the user equipment, which obtains the indication information based on its modem resolution.
As a variation, the data may also be transmitted to the user equipment via Over-the-Air Technology (OTA) or OPEN MOBILE ALLIANCE (OMA).
Further, the forbidden list may include at least one sub-list, and the indication information is used to indicate one or more sub-lists in the at least one sub-list. Taking the list of the PLMN which is prohibited from accessing as an example, the list of the PLMN which is prohibited from accessing may include a forbidden PLMN list, a list of forbidden PLMNs for attaching in the S101 mode, and a list of forbidden PLMNs for general packet radio service technology, and so on, and the indication information may be used to indicate the forbidden PLMN list therein; alternatively, the indication information may be used to indicate a list of forbidden PLMNs and a list of forbidden PLMNs for general packet radio service technology.
In a preferred application scenario, the step S102 may include: deleting one or more sub-lists indicated in the indication information in the forbidden list. For example, the indication information is used to indicate a forbidden PLMN list in at least one sub-list included in the list of PLMNs to which access is prohibited, and the user equipment deletes the forbidden PLMN list after receiving the indication information, and retains other sub-lists included in the list of PLMNs to which access is prohibited except for the forbidden PLMN list.
In a variation of this embodiment, the forbidden list may include at least one sub-list, each sub-list includes one or more elements, and the indication information is used to indicate an element to be deleted. Taking the list of the PLMN to be barred from access as an example, the list of the PLMN to be barred from access may include a forbidden PLMN list, a list for a forbidden PLMN attached in the S101 mode, and a list for a forbidden PLMN of a general packet radio service technology, and multiple sublists, where each sublist includes one or more PLMNs, and the indication information is used to indicate a specific PLMN to be deleted.
In a preferred application scenario of this variation, the step S102 may include: determining a to-be-processed sub-list according to the indication information, wherein the to-be-processed sub-list comprises the to-be-deleted elements; and deleting the elements to be deleted indicated in the indication information from the to-be-processed sub-list. For example, the network may not be able to determine a specific storage location of a PLMN to be deleted, which is desired to be deleted by the user equipment (i.e., the network does not know in which sub-list the PLMN to be deleted is stored by the user equipment), the network informs the user equipment of the PLMN to be deleted, which needs to be processed this time, through the indication information, the user equipment determines the storage location of the PLMN to be deleted, determines the sub-list in which the PLMN to be deleted is recorded as the sub-list to be processed, and then deletes the PLMN to be deleted from the sub-list to be processed.
Further, there may be more than one element to be deleted, and multiple elements to be deleted may be recorded in the same or different sub-lists, so for each element to be deleted, the user equipment determines the sub-list where the element to be deleted is located as the sub-list to be processed, and deletes the element to be deleted from the sub-list to be processed.
In another preferred application scenario of this variation, the indication information may also indicate the to-be-deleted sub-list, but the indication information does not explicitly indicate the to-be-deleted element that needs to be deleted in the to-be-processed sub-list, but indicates the user equipment by way of an indication condition, and the user equipment determines, according to the indication condition, one or more elements that meet the indication condition from the to-be-processed sub-list as the to-be-deleted element, and then deletes the to-be-deleted element indicated by the indication information from the to-be-processed sub-list.
For example, the network wants the user equipment to delete a part of elements in a sub-list, and the network does not know which PLMNs are specifically stored in the list of the forbidden PLMNs attached in the S101 mode of the user equipment, but the network also wants the user equipment to delete one or more PLMNs in a specific signal coverage range in the sub-list, the network informs, through the indication information, that the to-be-deleted PLMN that the user equipment needs to process this time is a PLMN whose signal coverage range is in the specific signal coverage range (i.e., the indication condition), the user equipment determines, as the to-be-deleted PLMN, a PLMN that satisfies the indication condition in the list of the forbidden PLMNs attached in the S101 mode that is stored in the user equipment, and then deletes the to-be-deleted PLMN from the list of the forbidden PLMNs attached in the S101 mode.
In another variation of this embodiment, before executing step S101, the following steps may be further executed: and reporting the registration information of the currently registered sub-network to the network. Wherein the network may be a main network of the sub-network (e.g., the sub-network may correspond to a cell, and a set of signal coverage of each of a plurality of cells may correspond to the signal coverage of the main network), which is used for upper-level control of data interaction of the sub-network with a user equipment. For example, the user equipment may report information of the currently registered sub-network to the network after completing registration or during data interaction with the sub-network after completing registration, and if the network considers that the sub-network where the user equipment is currently camped is not a necessary and best network (e.g., determined based on an updated roaming agreement), the network may instruct the user equipment to delete the forbidden list to (also referred to as re-) select a sub-network from the beginning (i.e., re-perform cell selection).
Further, referring to fig. 4, in a typical application scenario adopting this embodiment, the user equipment 1 configures a T3245 timer, and when a registration attempt for a PLMN in the network 2 fails (e.g., when any reason (e.g., attach reject, tracking area update reject, service reject, etc.) related to a forbidden PLMN sent by the network 2 is received), the user equipment 1 performs an action s1 to add the PLMN attempting access this time to an appropriate FPLMN list; and the user equipment 1 further performs action s2 to activate the T3245 timer. Unlike the prior art, before the T3245 timer expires, the network 2 may send an indication message to the user equipment 1 through the access stratum message or the non-access stratum message to instruct the user equipment 1 to delete at least a part of the contents in the forbidden list stored by the user equipment 1.
Further, the user equipment 1 may perform an action s5 to stop the T3245 timer after receiving the indication information sent by the network 2; and an action s6 is performed to delete at least a part of the content in the forbidden list according to the indication information. Further, the user equipment 1 may also perform action s7 to start a cell selection procedure.
In a variation of the present application scenario, the execution order of the actions s5 and s6 may be interchanged, or the actions s5 and s6 may be executed synchronously.
Further, referring to fig. 5, in another exemplary application scenario adopting this embodiment, the user equipment 1 does not configure the T3245 timer, or the user equipment 1 does not support the T3245 timer, when the registration attempt for one PLMN in the network 2 fails (for example, when any reason related to the forbidden PLMN (for example, attach reject, tracking area update reject, service reject, and the like) sent by the network 2 is received), similar to the prior art, the user equipment 1 performs an action s1 to add the PLMN attempting access this time to the appropriate FPLMN list. However, unlike the prior art, according to the technical solution of the present embodiment, the ue 1 does not have to wait for a specific event to occur, but can process the stored forbidden list based on the indication information of the network 2.
For example, when the network 2 considers that the signal quality of the sub-network where the user equipment 1 currently resides (may also be referred to as camping) is not good, an indication message may be sent to the user equipment 1 through the access stratum message or the non-access stratum message to instruct the user equipment 1 to delete at least a part of the contents in the forbidden list stored by the user equipment 1, so that the user equipment 1 can register to the sub-network with better signal quality when cell selection is restarted.
Further, the user equipment 1 may perform an action s6, after receiving the indication information sent by the network 2, to delete at least a part of the content in the forbidden list according to the indication information. Further, the user equipment 1 may also perform action s7 to start a cell selection procedure.
With continuing reference to fig. 4 and 5, the indication may preferably be sent based on the access stratum message or a non-access stratum message, and may also be sent based on a new message dedicated to indicating deletion of the forbidden list.
Preferably, the indication information may be used to indicate specific list information (e.g. one or more sub-lists in the forbidden list, or elements included in one or more sub-lists) to further optimize the behavior of the user equipment 1.
