In order to make the purpose and technical solution of the present application more clear and intuitive, the following describes in detail a terminal roaming management method and a management apparatus provided in the present application with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Fig. 2 is a schematic flow chart of a terminal roaming management method 200 in the embodiment of the present application. The method 200 may be applied to the system architecture 100 shown in fig. 1, but the embodiment of the present application is not limited thereto. As shown in fig. 2, the method 200 includes the following steps:
s201, the location management device receives location update information from the core network device.
It should be understood that the location update information is used to indicate that the location of the terminal has changed, the location update information carries an identifier of the terminal and an identifier of the core network device, and the identifier of the core network device is used to indicate the current location of the terminal device.
Optionally, in this embodiment of the present application, the core network device may be a Mobile Switching Center (MSC) or a Mobility Management Entity (MME), the identifier of the terminal may be an International Mobile Subscriber Identity (IMSI), and the identifier of the core network device may be a mobile switching center number (MSC number) or a mobility management entity Identity (MME Identity).
For example, for the third generation mobile communication technology (3rd generation,3G), the location management device may receive location change information sent by the core network device MSC through the 3G network, and the core network device MSC sends first location update information to a Home Location Register (HLR), where the first location update information carries a terminal identified by the IMSI and a core network device MSC identified by an MSC number.
For example, for the fourth generation mobile communication technology (4rd generation,4G), the location management device may also receive location change information sent by the core network device MME through the 4G network, and the core network device MME sends second location update information to a Home Subscriber Server (HSS), where the second location update information carries the terminal identified by the IMSI and the core network device MME identified by the MME Identity.
S202, the location management device determines whether a roaming restriction policy exists for the terminal and/or the current location according to the location update information, and determines whether the terminal is in a roaming state.
The IMSI Identity may be used to set a roaming restriction policy for the terminal, and the MSC number/MME Identity may be used to set a roaming restriction policy for the current location of the terminal.
For example, the location management device may determine whether a roaming restriction policy exists for the terminal and/or the current location and whether the terminal is in a roaming state according to the IMSI identifier and the MSC number/MME Identity identifier.
S203, if the terminal is in roaming state and the roaming restriction policy of the terminal and/or the current location exists, the location management device sends a service change request to the operator side device according to the roaming restriction policy.
In the embodiment of the present application, the location management device receives location update information from the core network device, and according to the location update message, the location management device determines that a roaming restriction policy exists for the terminal and/or the current location, and the terminal is in a roaming state, and then the location management device sends a service change request to the operator-side device according to the roaming restriction policy, so as to change the service of the terminal.
Therefore, the terminal roaming management method of the embodiment of the application realizes flexible management of terminal roaming by configuring the roaming restriction policy through the position updating message, realizes restriction and recovery of terminal services by communicating with the operator side, and reduces perception of the user on the terminal services and influence on the network.
As an optional embodiment, the method further includes: if the terminal is not in the roaming state, the position management equipment judges whether the service of the terminal is changed; if the service of the terminal is changed, the location management device sends a service recovery request to the operator side device, wherein the service recovery request is used for requesting to recover the service of the terminal.
Specifically, the terminal is not currently in a roaming state, and there may be two cases, one is that the terminal never roams, and the other is that the terminal has roamed but returned to the home. Therefore, the location management device needs to determine whether the service of the terminal has been changed. If the service of the terminal is changed, the terminal is shown to have roamed; if the service of the terminal is not changed, the terminal never roams. If the service of the terminal is not changed, the position management equipment does not need to execute any operation; if the service of the terminal is changed, but the terminal is not in the roaming state because the terminal has returned to the home location currently, the location management device needs to send a terminal service recovery request to the operator side device, where the service recovery request is used to request that the terminal service is recovered to the service not in the roaming state. Therefore, the terminal service can be timely and effectively recovered.
As an optional embodiment, the method further includes: if the roaming restriction policy of the terminal and/or the current position does not exist, the position management equipment judges whether the service of the terminal is changed; if the service of the terminal is changed, the location management device sends a service recovery request to the operator side device, and the service recovery request is used for requesting to recover the service of the terminal.
Specifically, there is no roaming restriction policy for the terminal and/or the current location, indicating that no service change is required for the terminal. However, since the terminal may have roamed to another location where the roaming restriction policy exists before and the service change has been made at another location where the roaming restriction policy exists, the location management apparatus can determine whether the service of the terminal has been changed. If the terminal roams to other positions with roaming restriction policy before, the service of the terminal is changed, and the position management device can send a service recovery request to the operator side device to recover the previously restricted service of the terminal; if the terminal does not roam to other positions where the roaming restriction policy exists before, the service of the terminal is not changed, and the position management device does not need to execute any operation.
As an optional embodiment, the roaming restriction policy of the terminal and/or the current location includes at least one of the following: the method comprises the steps that service change is not carried out on specific terminals in a first white list, and the first white list comprises at least one specific terminal identification; not performing service change on the terminal in a specific position in a second white list, wherein the second white list comprises at least one identifier of the specific position; and not performing service change on the specific terminal at the specific position in a third white list, wherein the third white list comprises the corresponding relation between the identification of at least one specific terminal and the identification of at least one specific position.
In a first possible implementation manner, the first white list is a policy for a terminal, and is determined mainly by a terminal identifier (e.g., IMSI), if the terminal identifier (IMSI) exists in the white list, release is performed, and the terminal service is not changed, otherwise, the location management device may send a service change request to the operator-side device.
In a second possible implementation manner, the second white list is a policy for a terminal location, and is determined by a terminal location identifier (e.g., MSC number/MME Identity), and if the terminal is within a legal range specified by the list, the release is performed, and the terminal service is not changed, otherwise, the location management device may send a service change request to the operator-side device.
In a third possible implementation manner, the third white list is a policy for a specific terminal and a specific terminal location, and joint determination is performed through a terminal identifier (e.g., IMSI) and a terminal location identifier (e.g., MSC number or MME Identity), if the terminal and the terminal location are in the list, release is performed, and the terminal service is not changed, otherwise, the location management device may send a service change request to the operator-side device.
The embodiment of the present application implements management of terminal roaming through a set white list, and it should be understood that in another possible implementation manner, management of terminal roaming may be implemented through setting a black list, which is not limited in the embodiment of the present application. Exemplarily, a service change is performed on a specific terminal in a first blacklist, where the first blacklist includes an identifier of at least one specific terminal, and specifically, the first blacklist is a policy for the terminal and is mainly determined by a terminal identifier (e.g., IMSI), if the terminal identifier (IMSI) does not exist in the blacklist, release is performed, and the terminal service is not changed, otherwise, the terminal service change request is sent to the operator-side device through a location management device.
As an optional embodiment, the roaming restriction policy of the terminal and/or the current location further includes: and for a fourth white list, not performing service change on a specific terminal located in a specific position within a specific time duration, wherein the fourth white list includes a corresponding relationship among at least one specific time duration, an identifier of at least one specific terminal and an identifier of at least one specific position.
It should be understood that the fourth white list is a relaxed constraint policy for the specific terminal and the specific terminal location, that is, the policy may be understood as an extension of the third white list, as long as by setting the specific time duration, when the stay time of the specific terminal at the specific location does not exceed the specific time duration, release is performed, and no service change is performed on the terminal, otherwise, the location management device may send a service change request to the operator-side device.
Illustratively, when the terminal is located at a specific location for the first time, it should be understood that the specific location here may be a boundary between a home location and a visited location of the terminal or a certain range of the visited location, and the location management device may start a timer, where a duration of the timer is a specific duration corresponding to the terminal and the specific location in the fourth white list. At this time, if the location of the terminal is updated and is within the legal location range, it should be understood that the legal location range is the range of the home location of the terminal, i.e. it indicates that the terminal is currently in the non-roaming location range, the location management device may delete the timer; if the terminal is updated and is not in the range of the specific position, the position management device can directly send a service change request to the operator side device; if the terminal is updated and is within the specific location range, the location management device does not perform any operation, but when the timer expires, the location management device may directly transmit a service change request to the operator-side device even if the terminal is within the specific location range.
As an optional embodiment, the changing the service of the terminal includes at least one of the following: the position management equipment changes the user level of the terminal; the position management equipment changes the service level of the terminal; or the position management equipment changes the data layer of the terminal; the change of the user plane comprises executing shutdown operation on the terminal, the change of the service plane comprises executing change or limitation on voice or data service of the terminal, and the change of the data plane comprises limiting an address range accessed to the internet of the terminal on a home domain network element.
It should be understood that the change to the service of the terminal is not limited to the above-mentioned change operation, but may also be other service changes, and the embodiment of the present application does not limit this.
It should be understood that, after triggering the terminal service change according to the policy, the location management device sends the terminal service change to the operator side device to complete the instruction issuing and implementation of the terminal specific service change. After the terminal service is changed, the operator side device not only receives the terminal service recovery request from the position management device, but also allows the terminal to reply the relevant service restriction through a mobile phone business hall, a short message business hall, an online business hall or an entity business hall. The operator side equipment can obtain the current position information of the terminal by calling the interface of the position management equipment, and replies normal use of the related service of the terminal after judging that the terminal is in a legal area.
Illustratively, the terminal's home location is at location a, and the terminal often travels to and from location A, B. For the terminal, when the policy set on the location management platform is a fourth white list, i.e., a loosely constrained policy for a specific terminal and a specific terminal location, the timer is initially set to 5 hours.
When the terminal enters the place B or the border between the place A and the place B and resides in the network of the place B, the terminal generates corresponding position update, and the position management platform starts the timer after receiving the position update information of the terminal. If the terminal does not return to the A place within 5 hours, carrying out service change on the terminal, such as incapability of surfing the Internet or calling; if the terminal returns to the A place within 5 hours, no service change is carried out on the user. Therefore, the perception of the user on the change of the terminal service is effectively reduced.
As an optional embodiment, the method further includes: the location management device optimizes the specific duration corresponding to the specific terminal according to historical location data of the specific terminal, wherein the historical location data comprises an identifier of the specific terminal, an identifier of a location where the specific terminal is located and location update time of the specific terminal.
It should be understood that, the terminal identifier, the location identifier, and the timer duration, that is, the specific duration corresponding to the specific terminal, are stored in the terminal management device, where the mapping relationship between the location identifier and the MSC number/MME Identity identifier is also stored by the location identifier, that is, which MSC number/MME Identity the location includes. At the same time, the position information record of the terminal is stored, and the position information record at least comprises the user identification, the position identification and the position updating time. Optimizing the specific time length corresponding to the specific terminal, specifically comprising the following steps:
s1: and (6) initializing data. Initializing the time length of a timer to alpha;
s2: and (5) processing historical position data. For the position information record of the user at the latest T time, the position information record is recorded from morning to evening according to the timeAfter the position updating records are arranged in sequence, the time of staying at the first position is calculated according to the time difference of the updating records of two continuous positions. For a specific location area, Δ t is recorded by the associated dwell time n times1,Δt2,Δt3…Δtn。
S3: for a specific position area, if n is larger than or equal to k, analyzing the distribution condition of the residence time of the specific position area, and turning to a step 4;
it should be understood that k here is an upper limit of the number of times the terminal stays in the specific location area, and n is an actual number of times the terminal stays in the specific location area.
Illustratively, when k is 10, the terminal actually stays in the specific location area 11 times, i.e. n is 11, and n ≧ k triggers the optimization of the timer time α.
S4: see if the dwell time corresponds to the relevant distribution and record the corresponding usual dwell time t.
In particular, if the dwell time Δ t1,Δt2,Δt3…ΔtnIs a power law distribution and has a residence time deltat exceeding 80%1,Δt2,Δt3…ΔtnWithin the value t, i.e. the dwell time Δ t1,Δt2,Δt3…ΔtnThe probability of being less than t is 80%, the timer time alpha is optimized by using the strategy in S4;
otherwise the timer time alpha is set to the dwell time deltat1,Δt2,Δt3…ΔtnAverage value of (a).
S4: the timer duration is optimized according to different strategies.
Strategy one: and (4) loose optimization. Alpha is in the range of t, infinity), the update rule is as follows
And (2) strategy two: the lower bound is strictly optimized. The value range of alpha is [ min, t ], alpha is initialized to min in step 1, and the updating rule is as follows
Strategy three: the upper bound is strictly optimized. The value range of alpha is [ t, max ], alpha is initialized to max in step 1, and the updating rule is as follows
And (4) strategy four: the upper and lower boundaries are strictly optimized. The value range of alpha is [ min, max ], alpha is initialized to min in step 1, and the updating rule is as follows
For example, the terminal frequently travels back and forth at A, B, and when the terminal location resides in the network at location B, the location management device starts a corresponding timer after receiving the location change message, for example, the timer initialization time may be 5 hours, that is, if the terminal does not return to location a within 5 hours, the location management device sends a service change request to the operator side to change the service of the terminal, for example, the terminal cannot surf the internet or talk; if the user returns to the A place within 5 hours, the position management equipment does not send a service change request to the operator side, and the terminal does not change the service. If the terminal stays in B within 30 days recently and the power law distribution is presented, and 80% of the time value is within 8 hours, the timer can be optimized to 8 hours through strict optimization of the lower bound in the optimization strategy. After the optimization, the terminal can not trigger service change under most conditions, so that the pressure on equipment on the side of an operator is reduced, and the perception of a user on the service change of the terminal is also reduced.
Fig. 3 is a schematic flowchart of another terminal roaming management method 300 according to an embodiment of the present disclosure. As shown in fig. 3, the specific steps are as follows:
the position management equipment receives terminal position updating information sent by the central network equipment;
and the position management equipment judges whether the terminal has a roaming restriction strategy or not according to the information.
If no roaming restriction policy exists, the location management device determines whether the terminal has performed a service change. If the terminal has performed service change, the location management device sends a service recovery request to the operator side; otherwise, the operation terminates.
If the roaming restriction policy exists, the location management device judges whether the terminal is in a roaming state.
If the terminal is in a roaming state, the position management equipment judges the strategy according to a roaming management strategy and sends a service change request to an operator side so as to change the strategy of the terminal; otherwise, the position management device judges whether the terminal has performed service change. If the terminal has performed service change, the position management device sends a service recovery request to the operator side; otherwise, the operation terminates.
