Description
Technical Field
The present invention relates to the field of mobile communications, and in particular, to a method and an apparatus for updating a capability of a mobile terminal, and a mobile terminal.
Background
LTE (Long Term Evolution) is considered as an Evolution direction of next generation mobile communication by industry as a 3G (third generation mobile communication technology) subsequent Evolution technology with its unique technical advantages of high data rate, low delay, flexible bandwidth configuration, and the like. For operators, after LTE is introduced, mobile terminals of the operators are required to support an LTE mode and a corresponding operating frequency band on the basis of an original multimode, and also to support an operating frequency band that can ensure users to implement international roaming. Unlike 2G (second generation mobile communication technology)/3G era, currently, globally allocated LTE spectrum is numerous and relatively discrete, and in order to better support international roaming, a mobile terminal needs to support more frequency bands. Taking a certain chinese operator as an example, after TD-LTE (Time Division long Term Evolution) is introduced, in order to meet the operation requirements of the Mobile terminal, the Mobile terminal needs to support at least three modes of TD-LTE, TD-SCDMA (Time Division-Synchronous Code Division Multiple Access), GSM (Global System for Mobile Communication, Global System for Mobile communications), and eight frequency bands to ensure the continuity of the service, specifically see table 1.
In order to improve the international roaming experience of users, the mobile terminal needs to support an FDD (frequency division duplex) LTE mode, and in combination with the current situation of global FDD LTE deployment, currently, NGMN (next generation mobile communication network) recommends that the mobile terminal needs to support at least band1/7/17 (or 13)3 frequency bands to roam to parts of japan, europe, and usa through FDD LTE, and as the global deployment scale of FDDLTE gradually expands, the mobile terminal needs to add a new FDD LTE frequency band to implement global roaming. Considering that WCDMA (Wideband Code Division Multiple Access) has a wide global deployment range, high maturity and strong roaming capability, in order to improve the international roaming capability of the mobile terminal, the mobile terminal is encouraged to support a WCDMA mode and a corresponding working frequency band, and table 1 provides the mainstream deployment frequency bands of all systems worldwide.
Table 1 mainstream deployment frequency band of each system
Because the LTE multimode multi-frequency mobile terminal supports a plurality of systems and frequency bands, if the mobile terminal starts to use all frequency bands, signal transmission and reception of different frequency bands will bring a large overhead to the radio frequency device of the mobile terminal, and will increase the power consumption of the mobile terminal greatly. When the mobile terminal roams to other countries/regions, the mobile terminal updates the supported frequency bands according to the frequency band deployment condition of the roaming country/region. For example, as shown in fig. 1, the mobile terminal reports and supports LTE bands band3, 38, 39, 40, and 41 in continental china, and reports and supports LTE bands band3, 7, 8, and 40 when roaming to hong kong.
The operators in two countries/regions in border areas cannot perform cell reselection/handover/redirection with each other due to different PLMNs (Public Land mobile networks). Even if the mobile terminal can measure that the network signal of the opposite side is very strong, the mobile terminal can only be dragged to off-line and then registered through network search and network selection, the communication interruption time of a user is long, and the probability problem that the network is automatically selected to a non-partner network exists.
The role of the EPLMN (equivalent PLMN) is that when roaming across PLMNs, the mobile terminal preferentially selects the PLMN recommended by the subscription registration network, protecting the interests of the home operator. The EPLMN function enables the mobile user to consider different PLMN codes as being equal in place of each other when selecting a PLMN, which can be applied in the case of PLMN selection, Cell (re) selection, handover. The network sends the EPLMN list to the mobile terminal during Location Update, Routing Area Update, Tracking Area Update, GPRS Attach, and LTE Attach, and the mobile terminal will store the EPLMN list and the PLMN that sent the list together in the "availability PLMNs" table of the mobile terminal.
If the border area network is deployed with the EPLMN, specifically, the PLMN ID (identity) of the local country/area operator network is configured as the EPLMN of the local country/area network by the local country/area operator, the mobile terminal in the area can perform cell reselection from the local country/area network to the adjacent country/area network in an idle state, perform handover or redirection from the local country/area network to the adjacent country/area network in a connected state, and perform registration through network search and network selection after being not dragged to a disconnected network, thereby greatly saving the time delay of roaming registration.
In the roaming scene based on the EPLMN, a problem that the mobile terminal does not update the supported frequency band may occur, which may result in that a part of the frequency band of the neighboring country/region network cannot be accessed, because the mobile terminal does not determine that the mobile terminal is in the roaming state according to the change of the EPLMN, and updates the supported frequency band of the corresponding roaming country/region.
For example, as shown in fig. 2, the mobile terminal reports the LTE supported bands band3, 38, 39, 40, and 41 in continental china, assuming that the border is covered with the band 40 network in hong kong, when roaming to hong kong based on EPLMN, the mobile terminal does not determine that it is in roaming state, and still reports the LTE supported bands band3, 38, 39, 40, and 41, resulting in an LTE network that cannot access hong kong band 7; assuming that the border only covers the band 7 network in hong Kong, the band 7 is not measured because the mobile terminal does not update the supported frequency band, so that the EPLMN-based reselection/redirection cannot be performed.
The mobile terminal reports and supports LTE frequency bands band3, 7, 8 and 40 in hong Kong area, supposing that the border is covered with band 40 network of China continental area, when roaming to China continental area based on EPLMN, it is not judged that the mobile terminal is in roaming state, and reports and supports LTE frequency bands band3, 7, 8 and 40, which results in that LTE network of China continental band 38 and band39 can not be accessed; assuming that the border only covers the band 38 or band39 network in the continental area of china, the band 38 and band39 cannot be measured because the mobile terminal does not update the supported frequency band, so that the reselection/redirection based on the EPLMN cannot be performed.

EXAMPLE III
The embodiment also provides a mobile terminal, which comprises the capability updating device of the mobile terminal.
The capability updating method of the mobile terminal of the present invention is further described below with reference to specific scenarios:
in a first scenario, when a mobile terminal moves from a tracking area configured with an EPLMN to a tracking area configured with the EPLMN in a power-on state, or when the mobile terminal performs power-on registration in the tracking area configured with the EPLMN, the capability updating method of the mobile terminal of the present invention includes the following steps:
1) the mobile terminal acquires the EPLMN, and specifically, the mobile terminal may acquire the EPLMN in the following manner: the mobile terminal receives an attachment acceptance signaling which is issued by a network side and comprises an EPLMN; or the mobile terminal receives a tracking area update receiving signaling which is sent by the network side and comprises the EPLMN;
2) the mobile terminal compares the first country code in the EPLMN with the second country code in the HPLMN stored in the SIM (subscriber identity Module) card of the mobile terminal, and when the first country code is different from the second country code, the EPLMN is judged to belong to a country (border).
3) The mobile terminal releases the limit of the domestic mode according to the country/region corresponding to the first country code in the EPLMN, updates the wireless capability of the mobile terminal into the international mode, and mainly increases the non-domestic communication system/frequency band, for example, for a certain China operator to customize the mobile terminal, the domestic mode only supports three-mode TD-LTE/TD-SCDMA/GSM, does not support LTE FDD, and GSM only has 2 frequency bands, while the international mode supports four-mode including LTE FDD, and GSM has 4 frequency bands, the mobile terminal automatically starts the support of the LTE FDD communication system, and starts the support of 2 overseas frequency bands of GSM
4) And the mobile terminal reports the updated wireless capability to the network side.
Specifically, if the mobile terminal is in an idle state, the mobile terminal reads a non-domestic communication system/frequency band (for example, foreign LTE FDD) neighboring cell broadcasted by the network, and performs measurement and reselection evaluation. And reporting the updated wireless capability in the capability reporting signaling in the access network.
If the mobile terminal is in a connected state, the mobile terminal reports the wireless capability by the following two methods:
the method comprises the following steps: the mobile terminal initiates detachment to the network side, then the mobile terminal initiates the attachment process to the network side again, and reports the updated wireless capability in the capability reporting signaling;
the second method comprises the following steps: the method comprises the steps that a mobile terminal initiates a tracking area updating request for updating the wireless capability of the mobile terminal to a network side, specifically, UE radio capability information updated IE in a tracking area updating request signaling is set as TRUE, an MME (mobile management entity) clears the stored wireless capability of the mobile terminal, and then when a DRB (data bearer) is established again, the mobile terminal capability query request is issued again because a service base station at the network side cannot obtain the wireless capability of the mobile terminal from the MME, and at the moment, the mobile terminal reports the updated wireless capability to the network side.
And in a second scenario, when the mobile terminal moves from the tracking area configured with the EPLMN to the tracking area not configured with the EPLMN in the power-on state, and the tracking area issued by the network side receives a signaling to find that the EPLMN is not configured, the mobile terminal updates the wireless capability to a domestic mode, for example, for a certain China operator to customize the mobile terminal, the support for the LTE FDD communication system is closed, the support for the GSM 2 overseas frequency bands is closed, and then the mobile terminal reports the updated wireless capability to the network side. The mobile terminal reports wireless capability by the following two methods:
the method comprises the following steps: the mobile terminal initiates detachment to the network side, then the mobile terminal initiates the attachment process to the network side again, and reports the updated wireless capability in the capability reporting signaling;
the second method comprises the following steps: the method comprises the steps that a mobile terminal initiates a tracking area updating request for updating the wireless capability of the mobile terminal to a network side, specifically, UE radio capability information updated IE in a tracking area updating request signaling is set as TRUE, an MME (mobile management entity) clears the stored wireless capability of the mobile terminal, and then when a DRB (data bearer) is established again, the mobile terminal capability query request is issued again because a service base station at the network side cannot obtain the wireless capability of the mobile terminal from the MME, and at the moment, the mobile terminal reports the updated wireless capability to the network side.
And in a third scenario, when the mobile terminal is started up in a tracking area without the configured EPLMN, the mobile terminal updates the wireless capability to be in a domestic mode after finding that the configured EPLMN is not configured, for example, for a certain China operator to customize the mobile terminal, the support for the LTE FDD communication system is closed, the support for the GSM 2 overseas frequency bands is closed, and the wireless capability is reported to the network side in the attachment process.
Taking a certain chinese operator five-mode mobile terminal as an example, in a specific embodiment, assuming that a chinese continent network deploys TD- LTE bands 38, 39, 40, 41, a chinese hong kong network deploys LTE FDD bands 3, 7, 8 and TD-LTE band 40, the chinese continent network configures an EPLMN (chinese hong kong network, PLMN ID is 45412) in a tracking area to which a border cell belongs, when the mobile terminal moves from the tracking area where the EPLMN is not configured in the chinese continent to the border cell where the EPLMN is configured in a powered-on state, or when the mobile terminal is powered-on registered in the border cell where the EPLMN is configured, the mobile terminal first determines that the EPLMN after receiving the EPLMN, finds that an MCC code (454) of the EPLMN is different from a country code (460) in an HPLMN stored in its own SIM card, that is determined that the EPLMN is outside the country (border), the mobile terminal updates wireless capability, and starts support for LTE communication systems, and reporting the LTE FDD bands 3, 7 and 8 and the TD- LTE bands 38, 39, 40 and 41 supporting the LTE frequency band to the network side.
The technical scheme of the invention can avoid the situation that the mobile terminal only supports the communication system and the frequency band corresponding to the country code in the HPLMN stored in the SIM card of the mobile terminal, so that the mobile terminal can not access different communication systems and frequency bands of adjacent national/regional networks in the EPLMN-based roaming scene, thereby improving the success rate of roaming and improving the experience of roaming users. In addition, the technical scheme of the invention only needs to change the mobile terminal, and does not need to change the network side, thereby reducing the implementation cost of the technical scheme and being easy to popularize and apply.
Many of the functional units described in this specification have been labeled as modules, in order to more particularly emphasize their implementation independence.
In embodiments of the present invention, modules may be implemented in software for execution by various types of processors. An identified module of executable code may, for instance, comprise one or more physical or logical blocks of computer instructions which may, for instance, be constructed as an object, procedure, or function. Nevertheless, the executables of an identified module need not be physically located together, but may comprise disparate instructions stored in different physical locations which, when joined logically together, comprise the module and achieve the stated purpose for the module.
Indeed, a module of executable code may be a single instruction, or many instructions, and may even be distributed over several different code segments, among different programs, and across several memory devices. Likewise, operational data may be identified within the modules and may be embodied in any suitable form and organized within any suitable type of data structure. The operational data may be collected as a single data set, or may be distributed over different locations including over different storage devices, and may exist, at least partially, merely as electronic signals on a system or network.
When a module can be implemented by software, considering the level of existing hardware technology, a module implemented by software may build a corresponding hardware circuit to implement a corresponding function, without considering cost, and the hardware circuit may include a conventional Very Large Scale Integration (VLSI) circuit or a gate array and an existing semiconductor such as a logic chip, a transistor, or other discrete components. A module may also be implemented in programmable hardware devices such as field programmable gate arrays, programmable array logic, programmable logic devices or the like.
In the embodiments of the methods of the present invention, the sequence numbers of the steps are not used to limit the sequence of the steps, and for those skilled in the art, the sequence of the steps is not changed without creative efforts.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
