Description

Location update method and user equipment

Technical field

The embodiments of the present invention relate to the field of communications technologies, and in particular, to a location update method and a user equipment.

Background technique

In the field of communication, when the user equipment is normally stationed on the network, the phenomenon that the called party prompts to shut down often occurs. This phenomenon is called implicit shutdown. Implicit shutdown will cause the user to miss the call and bring losses to the user.

At present, the main cause of the implicit shutdown is that the access network is inconsistent with the location update period (T3212) set by the core network to which it belongs. In the communication field, the access network is used to connect the user equipment data to the core network in a first-level manner to implement connection between the user equipment and the network. The core network is responsible for data exchange, forwarding, and connection. Multiple access networks can belong to the same core network.

After the user equipment selects the network, the user equipment obtains the location update period of the current cell through the message broadcasted by the access network. After the location update period is reached, the user equipment sends a location area update message to the access network again, and the access network reports the received location area update message to the core network, and the core network receives the user equipment that accesses the online report. After the location area update message, the state of the user equipment in the core network is changed to the power on state. When the location update period set by the access network and the access network to which the access network belongs is inconsistent, if the core network does not receive the location area update message of the user equipment accessing the online report within the specified time, the core network considers The user device is turned off. For example, the location update period of the core network is 30 minutes, that is, the core network requires the access network to report the location area update message of the user equipment every 30 minutes; the location update period of the access network is 36 minutes, that is, the access network requires the user equipment. The location area update message is sent every 36 minutes. When the standby time reaches 36 minutes, the user equipment sends a location area update message to the access network. However, when the core network is in standby for 30 to 36 minutes, the status of the user equipment in the core network is changed because the location area update message of the user equipment accessing the online report is not received. In the shutdown state, if another user initiates a call to the user, a phenomenon indicating that the user device has been turned off appears.

In order to solve the above problem of implicit shutdown of the user equipment, a new location update method needs to be proposed.

detailed description

The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

In the field of communication, when the location update period set by the access network and the core network to which the access network belongs is different, the user equipment in the normal network may be implicitly shut down. Because the implicit shutdown will cause the user to miss the call, it will bring irreparable damage to the user. Therefore, in order to reduce the implicit shutdown of the user equipment in the normal network, and improve the communication success rate, the embodiment of the present invention provides a location update method, in which the user equipment makes the actual location update period of the access network through autonomous learning. It is similar to the location update period set by the core network, and then the location update is performed according to the actual location update period. Referring to FIG. 1, the location update method provided in this embodiment is mainly applied to a scenario in which a user equipment switches between different cells. In addition, in this embodiment, after the user equipment resides in any cell, the user equipment acquires a location update period of the camped cell, and stores the obtained location update period in a cache database, where the cache database is used. Temporarily store the location update period. The method flow provided by the embodiment of the present invention includes:

101. After the device is powered on, the user equipment acquires a location update period of the cell in which the cell is located.

In this embodiment, the user equipment may be a terminal having a communication function, such as a mobile phone. With the development of the communication technology, the communication range of the user equipment is wider and wider. In order to provide the service to the user equipment quickly and accurately, the access network requires the user equipment to periodically report the location information of the location and report the user equipment. The location location information is reported to the core network to which the access network belongs. Based on the received location information, the core network performs location update on the user equipment, and changes the state of the user equipment in the core network to the power-on state. In the communication field, the period in which the user equipment reports the location information is a location update period, which is used to indicate the period duration in which the user equipment periodically performs the location area update, and the location update period is allocated by the core network to which the access network of the cell in the cell belongs.

When the user equipment is in the shutdown state, the user equipment does not need to process any communication service, and the user equipment does not initiate location update to the access network of the cell in which the user equipment is located. After the user equipment is powered on, the user equipment first selects the network to be accessed, and then initiates a location update request to the selected access network, where the location update request carries at least the user equipment identifier, the location information of the user equipment, and the like. After receiving the location update request, the access network of the cell where the user equipment is located reports the received location update request to the core network to which the user equipment belongs, and based on the received location update request, the core network identifies the cell identifier of the cell where the user equipment is located, The location update period and various configuration parameters are sent to the access network, and the access network carries the information to the user equipment. After the user equipment performs the shutdown operation in this embodiment, the stored location update period is cleared. Therefore, after the user equipment is powered on, the location update period of the cell that the user equipment acquires is the actual location update period.

It should be noted that, in this embodiment, when the user equipment is running, the user equipment acquires a location update period of the camped cell, and stores the obtained location update period. The manner of storing the acquired location update period includes, but is not limited to, storing the acquired location update period in a local storage unit. In addition, since the user equipment may be camped on multiple cells during operation, in order to avoid an error when the user equipment stores multiple location update periods, when the user equipment stores the acquired location update period, the corresponding The cell identity is stored together.

102. When the first cell is switched to the second cell, the user equipment acquires the location of the second cell. New cycle.

As the user equipment moves, the cell in which the user equipment is located is not static. When switching from the first cell to the second cell, the user equipment needs to perform location update again. At this time, the user equipment needs to send a location update request to the access network of the second cell, where the location update request carries at least the user equipment identifier, the user location information, and the like. After receiving the location update request sent by the user equipment, the access network of the second cell reports the received location update request to the affiliated core network. When receiving information such as the second cell identifier, the location update period, and the second cell configuration parameter delivered by the affiliated core network, the access network carries the information in the broadcast message and sends the information to the user equipment. Based on the received broadcast message, the user equipment may acquire a location update period of the second cell from the broadcast message. In fact, the location update period of the second cell is allocated by the second core network to which the access network of the second cell belongs, and the second core network is the core network to which the access network of the second cell belongs.

103. The user equipment acquires a location update period set.

The location update period set includes a location update period of the cell where the user equipment resides. The location update period set may be stored in the cache database, and the location update period stored in the cache database may be emptied under certain state triggers. For example, when the user device is shut down, the data in the cache database is emptied; or, when the core network where the user device resides changes, the data stored in the cache database is emptied.

In this embodiment, whether the data stored in the cache database is emptied directly affects the set of location update periods acquired by the user equipment. For example, when the data in the cache database is emptied, the location update period set obtained by the user equipment from the cache database is an empty set, and the location update period of each cell where the user equipment is not acquired by the user equipment is not obtained. When the data in the cache database is not cleared, the user equipment may obtain the location update period of each cell where the user equipment resides from the cache database.

The manner in which the user equipment obtains the location update period set may be different according to the manner in which the cache database is cleared. The details may be classified into the following cases.

The first case: when the user device is shut down, the data in the cache database is emptied.

In this case, when the user equipment is just powered on, the location update period set stored in the cache database is empty. When the user equipment camps on the cell, the location update period of the cell is saved in the cache database.

When the user equipment acquires the location update period set, there are two ways.

Method 1: The user equipment can obtain all the location update periods that have been stored from the cache database. For example, the cache database includes a location update period of the a cell of the core network A and a location update period of the b cell of the core network B. The user equipment acquires a location update period of the a cell and the b cell. When the user equipment is switched from the first cell to the second cell, the set of location update periods acquired by the user equipment is the same regardless of whether the core network where the user equipment resides changes.

Manner 2: The user equipment may obtain, from the cache database, a location update period of each cell of the core network where the stored second cell is located; that is, the obtained location update period set includes: location of each cell of the core network where the second cell is located renewal cycle. For example, the cache database includes a location update period of the a cell of the core network A and a location update period of the b cell of the core network B. When the core network where the second cell is located is the core network A, the user equipment acquires the location update period of the a cell. When the core network where the second cell is located is the core network B, the user equipment acquires the location update period of the b cell. When the user equipment is switched from the first cell to the second cell, the core network where the user equipment resides changes and does not change, and the location update period set acquired by the user equipment is different.

When the user equipment resides in each cell, the user equipment may store the cell identity of the camped cell and the corresponding location update period in the cache database. Therefore, based on the location update period stored in the cache database, when the user equipment obtains the location update period set from the cache database, the location update period set may be obtained from the cache database according to the identifier of the core network, where the location update period set is stored. The location update period of the cell where the user equipment resides.

The second case: when the core network where the user equipment resides changes, the data in the cache database is cleared.

In this case, when the core network where the user equipment resides has just changed, the location update period set stored in the cache database is empty, and the location update of the cell after the cell of the user equipment new core network resides. The cycle is saved in the cache database.

When the user equipment is handed over from the first cell to the second cell, if the core network to which the access network of the second cell belongs is different from the core network to which the access network of the first cell belongs, that is, if the user equipment resides When the core network changes, the user equipment clears the data in the cache database, that is, clears the previously stored location update period, and then re-records the location update period of the cell after the location. When the user equipment is switched from the first cell to the second cell, the core network where the user equipment resides does not change, and the user equipment acquires the stored location update period from the cache database.

The user equipment may determine, according to the stored configuration parameters, whether the LAI (Location Area Identity) of the two cells before and after the handover is the same; if the LAIs of the two cells before and after the handover are the same, the user equipment may be determined to be resident. The core network does not change; if the LAIs of the two cells before and after the handover are different, it can be determined that the core network where the user equipment resides changes. The configuration parameters may be MCC (Mobile Country Code), MNC (Mobile Network Code), and LAC (Location Area Code). LAI is a location identification code, which is composed of MCC, MNC and LAC. LAI is used to characterize the core network.

104. The user equipment determines an actual location update period of the second cell according to the location update period set and the location update period of the second cell.

In the field of communications, the main reason for the implicit shutdown of user equipment is that the location update period of the core network to which the access network and the access network belong is different. Normally, the location update period of the access network is larger than the location update period of the core network to which it belongs. Therefore, in the embodiment, after the location update period of the second cell is acquired, the user equipment does not directly use the acquired location update period as the second. The actual location update period of the cell, but the actual location update period of the second cell is determined according to the user equipment location update period set and the location update period of the second cell, so that the actual location update period of the second cell and the second core network The location update cycle is close.

When determining the actual location update period of the second cell according to the location update period set and the location update period of the second cell, the user equipment usually obtains the location update period set and the location of the second cell. In the new cycle, the smallest location update period is selected, and the minimum location update period is used as the actual location update period of the second cell.

For example, the cell in which the user equipment resides has a first cell, a third cell, and a fourth cell, and the location update period of the first cell in the acquired location update period set is 36 minutes, and the location update period of the third cell is At 42 minutes, the location update period of the fourth cell is 54 minutes. If the location update period of the second cell is 48 minutes, since the smallest of the location update periods of the first cell, the second cell, the third cell, and the fourth cell is the location update period of the first cell for 36 minutes, the user equipment The location update period of the first cell is 36 minutes as the actual location update period of the second cell. It should be noted that the location update period of the first cell, the third cell, and the fourth cell herein is only an example. In another case, when the user equipment first camps on the first cell and then camps on the third cell or the fourth cell; since the minimum location update period is selected each time, the stored first cell, third The location update period of the cell or the fourth cell is 36 minutes; at this time, only one data, that is, 36 minutes, may be reserved in the location update period set.

Further, the location update period in this embodiment is in units of minutes. In the actual implementation, the T3212 parameter can be used as the location update period. For example, the unit of setting T3212 is 6 minutes, and when T3212 is 5, it means that the position update period is 6*5=30 minutes.

105. The user equipment performs location update based on an actual location update period of the second cell.

After determining the actual location update period of the second cell, the user equipment sends a location update request to the access network with the actual location update period as the update duration. After receiving the location update request sent by the user equipment, the access network reports the location update request sent by the user equipment to the core network to which the user equipment belongs. Based on the received location update request, the core network performs location update on the user equipment, and changes the state of the user equipment in the core network to a power-on state. For example, the actual location update period of the second cell is 30 minutes; when the user equipment is in the second cell, the user equipment sends a location update request to the access network of the second cell every 30 minutes; and the access network is After receiving the location update request sent by the user equipment, the location update request is reported to the second core network to which the user equipment belongs, so that the second core network performs location update on the user equipment.

In addition, in order to save storage space, the method provided in this embodiment clears the location update period stored in the boot process of the user equipment after the user equipment is powered off.

The method provided by the embodiment of the present invention, when the first cell is switched to the second cell, the user equipment acquires the location update period of the second cell, and according to the location update period of the location update period of the cell where the user equipment is camped The set and the location update period of the second cell determine the actual location update period of the second cell, and then the user equipment performs location update based on the actual location update period of the second cell. When the location update is performed in the scenario of the cell handover, the user equipment does not simply use the acquired location update period as the actual location update period of the switched cell, but through autonomous learning, according to the location update period set and after the handover. The location update period of the cell is determined. This makes the actual update period of the cell after the handover close to the location update period set by the core network. Therefore, the frequency of the implicit shutdown of the user equipment is reduced, and the communication success rate is improved.

The embodiment of the present invention provides a location update method, where the method is applied to a scenario in which a user equipment switches between different cells, and when the user equipment switches from one cell to another, the core network of the two cells before and after the handover is Can be the same or different. In addition, in this embodiment, after the user equipment resides in any cell, the user equipment acquires the location update period of the camped cell, and stores the obtained location update period in the location area database, where the location area database Used to store data permanently. Referring to FIG. 2, the method process provided by this embodiment includes:

201. After being powered on, the user equipment determines an actual location update period of the cell in which the cell is located.

In this embodiment, since the location update period is permanently stored in the location area database, in order to avoid the implicit shutdown of the user equipment, when the user equipment is powered on, the user equipment is also obtained when the location update period of the cell is obtained. The actual location update period of the cell in question will be determined based on the location update period stored in the location database. For example, if the location area database stores the location update period of other cells that are the same core network as the core network of the cell where the user equipment is located, the location update period of other cells of the same core network stored in the location area database is The location update period of the current cell is compared, and the minimum location update period is used as the actual location update week of the current cell. If the location update database does not store the location update period of other cells in the same core network as the core network of the cell in which the user equipment is located, the obtained location update period is used as the actual location update period of the current cell.

It should be noted that, since the user equipment may reside in multiple cells during operation, in order to avoid an error when the user equipment stores multiple location update periods, the user equipment may store the acquired location update period. The identity of the core network and the corresponding cell identity are stored together.

202. When the first cell switches to the second cell, the user equipment acquires a location update period of the second cell.

The specific implementation of this step is the same as the foregoing step 102. For details, refer to step 102 above, and details are not described herein again.

203. The user equipment acquires, according to the identifier of the second core network, a location update period set of the second core network from the location area database.

The location area database is used to store the location update period, and the data in the location area database remains when the user equipment is shut down or the core network where the user equipment resides changes. Since the user equipment resides in each cell in the second core network, the user equipment stores a location update period in which the cell resides in the second core network, and therefore, based on the location update period stored in the location area database, the user When the device obtains the location update period set of the second core network from the location area database, the location update period set of the second core network may be obtained from the location area database according to the identifier of the second core network, where the second core network is located. The update period set is a set of location update periods of cells belonging to the second core network.

For example, the second core network is identified as A, and the cells that the user equipment resides in the second core network are the first cell, the third cell, the fourth cell, and the fifth cell, and the location update period of the first cell is 42 minutes. The location update period of the third cell is 48 minutes, the location update period of the fourth cell is 60 minutes, and the location update period of the fifth cell is 54 minutes. According to the second core network identifier A, the user equipment can obtain the location area database. Obtaining a location update period of the first cell for 42 minutes, a location update period of the third cell for 48 minutes, a location update period of the fourth cell for 60 minutes, and a location update week for the fifth cell The period is 54 minutes.

It should be noted that, in another embodiment, step 203 may be replaced by: the user equipment acquires a set of all the location update periods that have been stored from the location area database. For example, the location update period of the cell in which the plurality of core networks are stored in the location area database, and the user equipment acquires all the stored location update periods when acquiring the location update period set, instead of acquiring only the location update corresponding to the second core network. cycle.
