Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
A cell registration method, an apparatus, a terminal device, and a storage medium according to embodiments of the present application are described below with reference to the accompanying drawings.
In the related art, the current technical solution has a problem that there is no N26 interface between the core networks of the home 4G network and the visited 5G network, and after reselecting the cell from the home 4G network to the visited 5G network, the terminal will perform MRU (Mobility Registration) according to the 3GPP protocol, but the MRU will be received by the network for the reason # 9: the UE identity registered by the network (the network cannot acquire the device information of the terminal device) rejects, and then the terminal reselects and initiates initial registration according to the 3GPP protocol, and finally the terminal device can successfully register in the visited 5G network, which results in slow network residence of the terminal device.
Fig. 1 is a flowchart illustrating a cell registration method according to an embodiment of the present application.
An execution subject of the cell registration method in the embodiment of the present application is a cell registration apparatus, which may be disposed in a terminal device, where the terminal device may be a terminal device that needs to use a Subscriber Identity Module (SIM) card of a global system for mobile communications, for example, a smart phone, a telephone watch, a smart wearable device, and the like, which is not limited in this embodiment.
As shown in fig. 1, the method may include the steps of:
The target cell to be registered refers to a cell to which the terminal device is prepared to access through cell reselection in an idle state.
In the embodiment of the present application, in a roaming shared area, when a terminal device reselects a handover cell, the terminal device receives a system message sent by a Network device of a target cell to be registered, where the system message includes operator information carried by the target cell, for example, the operator information includes identification information of an operator, and is a Public Land Mobile Network (PLMN), and each operator has configured a corresponding PLMN.
And 102, under the condition that the operator information carried in the system message is not matched with the target operator information carried in the communication card of the terminal equipment, inquiring the target cell in the cell list.
The target operator information carried in the communication card of the terminal device is operator information to which the terminal device belongs, and the operator to which the terminal device purchases services, for example, if the terminal device is a mobile phone, and the communication SMI card in the mobile phone is a card issued by an operator a, the operator to which the mobile phone belongs is the operator a.
The cell list is a list of roaming cells with successful history registration. The terminal device moves from the cell of the operator to which the terminal device belongs to the visited operator cell, and registers in the visited operator cell successfully, and the visited cell after successful registration is a roaming cell. The method comprises the steps that after a terminal device is started for the first time, a cell list is generated, when the cell list is just generated, a roaming cell which is successfully registered does not exist, and therefore the cell list is empty, when the terminal device roams from an attributive target operator cell to an operator cell to be visited in an idle state, and after the operator cell to be visited is successfully registered, the roaming cell which is successfully registered in history is written into the cell list, namely the operator cell to be visited is written into the cell list, wherein the operator cell to be visited belongs to the operator to be visited, and the operator to be visited and the attributive operator share a network, namely after the terminal device roams to the operator cell to be visited, the terminal device can enjoy network service provided by the operator cell to be visited. The cell list can store a set number of cell information, wherein the cell information is not cleared in any state of the terminal equipment in the power-on, power-off, flight-on mode and flight-off mode. Therefore, the terminal device matches the operator information carried in the acquired system message with the target operator information carried in the communication card of the terminal device, and under the condition that the operator information carried in the system message is not matched with the target operator information carried in the communication card of the terminal device, the terminal device is in a scene of different-network roaming, and then a target cell is inquired in the cell list. It will be appreciated that writing an operator cell to the cell list is storing cell information for that operator cell in the cell list.
As an implementation manner, the cell information of the target cell may be compared with the cell information of each roaming cell stored in the cell list, and when the cell information of the target cell exists in the cell list, it is determined that the target cell is queried in the cell list; and determining that the target cell is not inquired when the cell information of the target cell does not exist in the cell list. The cell list stores cell information of each roaming cell, including PLMN information and cell identification information of the operator to which the roaming cell belongs. For example, the operator information indication carried in the system message is an operator a, and the set target operator information indication is an operator B, which indicates that the two pieces of operator information are not matched, where the operator information may be determined by a PLMN of the operator, for example, the operator may be determined to be the operator a or the operator B by the PLMN of the operator.
The heterogeneous network roaming can furthest promote the open sharing of the network, enhance the resource reuse and improve the overall development efficiency of the network, and is mainly applied to the heterogeneous network roaming of the 5G core network. The 5G core network inter-network roaming refers to that in an independent networking (SA) mode, in a roaming area, a terminal device accesses a 5G network of a visited operator from a network of a home operator through a roaming mode, and provides a 5G service for a user through the 5G network of the visited operator. The different network roaming refers to that basic network resources are mutually opened among several operators, different network users are allowed to access, the terminal equipment automatically roams to other operator networks under the conditions that the network resources of the home operator of the terminal equipment are poor, coverage is not realized, signals are poor, temporary faults and the like, other operators are visited operators, and the networks of the visited operators can ensure that users of the networks of the other accessed operators enjoy the same communication quality. Under the condition that a first network signal of a terminal device to-be-visited operator exists, the terminal device is switched to a first network of the visited operator from a second network of a home operator, wherein the first network is a shared network, and the network quality of the first network is higher than that of the second network. For example, in a heterogeneous network roaming scenario, a home operator and a visited operator of a terminal device share a 5G network, and when a 4G network signal of the home operator and a 5G signal of the visited operator coexist, the terminal device preferentially uses the 5G network of the visited operator.
In the embodiment of the present application, in response to the presence of the target cell in the cell list, that is, in response to the target cell being queried in the cell list, the terminal device sets the state to 5G system mobility management unregistered 5GMM-DEREGISTERED state, and in the 5GMM-DEREGISTERED state, the terminal device sends a request message of a first initial registration to the network device of the target cell to camp in the target cell, where the initial registration is a registration procedure performed by the terminal device at the time of reselection according to the third generation partnership project 3GPP protocol, and for differentiation, referred to as a first initial registration, specifically, in response to the presence of the target cell in the cell list, the first initial registration is completed by sending the request message of the first initial registration to the network device of the target cell, that is, the first initial registration is directly initiated when the target cell is in the cell list, and after the terminal equipment is successfully registered in the target cell through the first initial registration, acquiring the service provided by the operator network to which the target cell roams. Because the target cell already exists in the cell list, that is, the target cell is a roaming cell in which the history registration of the terminal device is successful, the registration failure due to the failure of acquiring the identity information of the terminal device is avoided through the first initial registration, the reliability of the registration of the target cell can be improved, and the network sharing is realized.
In the cell registration method of the embodiment of the application, a system message sent by network equipment of a target cell to be registered is received, and under the condition that operator information carried in the system message is not matched with target operator information carried in a communication card of terminal equipment, the target cell is inquired in a cell list, wherein the cell list is a list of roaming cells with successful history registration, and in response to the target cell being inquired in the cell list, a first initial registration request message is sent to the network equipment of the target cell. The roaming cell with successful history registration is maintained through the cell list, when the target cell is determined to exist in the cell list, the target cell is the roaming cell with successful history registration, under the condition that the operator information corresponding to the target cell to be registered of the terminal equipment is not matched with the operator information to which the terminal equipment belongs, the equipment information of the terminal equipment cannot be shared due to different operator networks, and the equipment information cannot be shared due to the fact that updating registration is adopted, so that the first initial registration request message is sent to the network equipment of the target cell, and the cell reselection efficiency is improved.
Based on the foregoing embodiment, fig. 2 is a schematic flowchart of another cell registration method provided in the embodiment of the present application, and as shown in fig. 2, the method includes the following steps:
Wherein, the resident source cell before cell reselection and the target cell belong to different mobile communication systems.
In the embodiment of the application, in a scenario of a heterogeneous network roaming, a terminal device roams from an affiliated operator network to a visited operator network, and when the terminal device is in a roaming area, the terminal device performs cell reselection to determine a target cell under a condition that signal quality of a cell where the terminal device resides cannot meet a communication requirement, for example, a signal is not covered, the signal quality is poor, and the like. In a scenario of roaming in a different network, as an example, fig. 3 is a schematic view of a scenario of roaming in a different network provided in this embodiment, as shown in fig. 3, the roaming in a different network occurs in a scenario where a home operator is PLMN1 and a visited operator is PLMN2, and in a scenario where a mobile communication system to which a resident cell belongs is a 5G network and a mobile communication system to which a target cell determined by reselection belongs is a 5G network; in another scenario, the mobile communication system to which the resident cell belongs is a 4G network, and the mobile communication system to which the reselected and determined target cell belongs is a 5G network.
The cell list is a list of roaming cells with successful history registration.
When a target cell is queried in a cell list, in an implementation manner of the embodiment of the present application, according to an addition order of roaming cells in the cell list, cell information of each roaming cell is compared with cell information of the target cell in an order from late to early in the addition order, so as to query the target cell in the cell list. The cell information of each roaming cell is compared with the cell information of the target cell according to the adding sequence from late to early, namely, the roaming cell added to the cell list at the latest is compared firstly, and the cell with the later adding sequence is probably the cell which is registered successfully recently, so that the cell information of the target cell to be registered is compared with the cell information of the cell with the later adding sequence firstly, the efficiency of determining the target cell can be improved, namely, the efficiency of inquiring the target cell in the cell list is improved.
Specifically, in step 202 to step 204, reference may be made to the explanations in the foregoing embodiments, and the principle is the same, which is not described herein again.
In the embodiment of the application, the target cell is in the cell list, and under the condition that the terminal device is successfully registered in the target cell through the first initial registration, indicating that the target cell is successfully registered again, the target cell can be regarded as a roaming cell to which the target cell frequently roams in the process of the foreign network roaming, since the number of roaming cells included in the cell list is a set number, when the set number is exceeded, it is necessary to delete roaming cells stored earlier in the cell list according to the addition order of each roaming cell, as an implementation, therefore, the adding order of the roaming cells in the cell list is determined based on the time sequence of successful registration, and thus, after the first initial registration is successful, the adding sequence of the target cell added to the cell list needs to be adjusted according to the time of the first initial registration, so that the accuracy of the adding sequence of each roaming cell in the cell list is improved. As another implementation manner, the adding order of the roaming cells in the cell list is determined based on the number of times of successful registration initiated to each roaming cell, for example, the adding order of the roaming cells in the cell list is changed from low to multiple orders according to the number of times of successful registration of the roaming cells, and after the first initial registration is initiated to the target cell, the adding order of the target cell added to the cell list is adjusted according to the number of times of successful registration of the target cell, so that the accuracy of the adding order of the roaming cells in the cell list is improved.
In the embodiment of the present application, in response to that a target cell does not exist in a cell list, that is, in response to that a target cell is not queried in the cell list, a request message for updating registration is sent to a network device of the target cell, that is, a target cell to be registered is not in the cell list, that is, the target cell is not a roaming cell in which a history registration of a terminal device is successful, but belongs to a cell within a registration area of the terminal device, and then it is necessary to initiate an update registration to the target cell.
The procedure of the update registration is that the terminal device sends a request message for updating the registration to the network device of the target cell, after receiving the request message for updating the registration, the network device determines an Access and Mobility Management function (AMF) of the target cell, which is called AMF1, AMF1 checks whether the Identity information of the terminal device exists, if the Identity information of the terminal device does not exist, a 5G global Unique Temporary identifier (5G global Unique UE Identity, 5G-GUTI) of the terminal device is checked, the 5G-GUTI is used to indicate the AMF corresponding to the terminal device, so that it can be determined which AMF retains the context information of the terminal device according to the 5G-GUTI, the AMF retaining the context information of the terminal device is called AMF2, and after determining the AMF2 retaining the Identity information of the terminal device, the AMF1 of the target cell will send an AMF2 retaining the context information of the terminal device to the AMF2 retaining the context information of the terminal device The identity information, and in turn, the AMF2 transfers the identity information of the terminal device to the AMF1 to which the current target cell belongs. When receiving the identity information of the terminal device transferred by the AMF2, the AMF1 to which the current target cell belongs notifies a Unified Data Management (UDM) unit to logout the identity information of the terminal device in the AMF 2. Further, the UDM recognizes the AMF1 to which the target cell belongs, and the AMF1 to which the target cell belongs transmits response information of successful update registration to the terminal device, so as to notify the terminal device of successful update registration. It can be understood that an error occurs in any link of the procedure of updating registration, which indicates that the terminal device fails to update registration.
In this embodiment of the present application, since Nx identifier interfaces between core networks of different operators are not open, the core networks of different operators cannot acquire the identity information of the terminal device through corresponding Nx interfaces, for example, cannot acquire the identity information of the terminal device through an N26 interface, and thus, when performing update registration, the network of the operator to be accessed rejects for a reason #9, where # 9: the identifier of the terminal device cannot be obtained from the network device, which results in a failure of updating registration, and further, the terminal device sends a request message for initial registration to the network device of the target cell according to the 3GPP protocol, which is called a request message for second initial registration for differentiation, that is, the second initial registration is initiated after the failure of updating registration, and the terminal device successfully registers in the target cell through the second initial registration.
In an implementation manner of the embodiment of the present application, the target cell is added to the cell list when the number of roaming cells included in the cell list is smaller than a number threshold.
In another implementation manner of the embodiment of the present application, when the number of roaming cells included in the cell list is greater than or equal to the number threshold, at least one roaming cell is deleted and a target cell is added to the cell list according to an addition order in which each roaming cell is added to the cell list, so as to update the cell list and improve accuracy of the cell list. The at least one roaming cell to be deleted may be deleted based on the ranking in the cell list. For example, the cell list includes 4 roaming cells, the ranking order is 1-4, the number threshold is 4, and the smaller the ranking, the earlier the time stored in the cell list is, the roaming cell ranked as 1 may be deleted, so as to add the target cell to the cell list.
In the cell registration method of the embodiment of the application, network interfaces between different mobile communication systems are not opened between different operators, so that equipment information of terminal equipment cannot be shared, registration cannot be successfully registered according to normal update, initial update is performed again after update registration fails, and network residence is slow. And initiating an updating registration to the target cell under the condition that the target cell does not exist in the cell list, adopting different registration modes under different scenes to improve the registration efficiency, and sending a second initial registration request message to the network equipment of the target cell after the updating registration fails. The method and the device have the advantages that a shared list, namely a cell list, is maintained at the terminal, and different registration modes are adopted, so that the registration speed of the target cell to be accessed is increased in the idle state of the terminal and in the scene that a home network moves to a visiting network, and the network residing efficiency of the terminal equipment is improved.
Based on the foregoing embodiment, fig. 4 is a schematic flowchart of another cell registration method provided in the embodiment of the present application, and as shown in fig. 4, the method includes the following steps:
The explanation of steps 401 to 404 in the foregoing embodiments can be referred to, and the principle is the same, which is not described again in this embodiment.
The indication information is used for indicating that the failure reason is the identity information acquisition failure of the terminal equipment.
And step 406, determining that the updating registration fails according to the indication information.
In the embodiment of the application, since the resident cell and the target cell belong to different mobile communication systems under different operators, the identity information of the terminal device is not shared, that is, a request message for updating the registration is initiated to the network device of the target cell, and the network device of the target cell fails to acquire the identity information of the terminal device, and further acquires the indication information sent by the network device of the target cell, and determines that the updating the registration fails according to the indication information. And then, after the updating registration fails, initiating a second initial registration to the target cell in an initial registration mode so as to ensure that the target cell is successfully registered and realize successful cross-network roaming.
Step 407 and step 408 may refer to the explanations in the foregoing embodiments, and the principle is the same, which is not described again in this embodiment.
In the cell registration method of the embodiment of the application, after the request message for updating registration is sent to the network device of the target cell, since the cell where the terminal device resides and the target cell belong to different mobile communication systems under different operators, the situation that the terminal device identity information is not shared between the two mobile communication systems exists, so that the updating registration fails because the identity information of the terminal device cannot be acquired, and after the updating registration fails, the second initial registration is initiated, so that the final registration succeeds in the target cell, the inter-network roaming is realized, and the network-residing efficiency of the terminal device is improved.
