Description
Technical field
Present invention relates in general to be updated in the optimum roaming list on the mobile radiotelephone with replaceable subscriber identification module (RUIM).The present invention is particularly useful for (but being not limited to) and determines whether existing optimum roaming list (PRL) needs to upgrade, in the multi-mode mobile radiotelephone or in RUIM, upgrade PRL then, thereby guarantee the back compatible of RUIM in the conventional wireless phone that adopts different radio access technologies.
Background technology
The mobile radiotelephone service-user requires high security and the convenience from the mobile service provider usually.Senior mobile radiotelephone characteristics, for example international roaming, aerial transmit (OTA) stipulates, and the interoperability between the dissimilar handheld device is more prevalent.Yet existing service still has many restrictions, needs the program of difficult usefulness to finish for example task of switching and update user information between handheld device usually.
Many restrictions of mobile telephone technology derive from the incompatibility problem between old and new standard and the technology.For example, the digital mobile radio telephone system is because the demand of the continuous growth of simulation mobile voice service produces.Yet numeral and artificial antenna telephone system are used the opposite end (opposite end) of wireless frequency spectrum, and it is common and digital system is incompatible therefore to be designed for the radio telephone of analogue system, and vice versa.In addition, different radio phone service provider adopts the different digital standard, thus a plurality of digital cordless phones only with certain specific criteria family compatibility.For example, global system for mobile communications (GSM) digital standard adopts at all Europe; And CDMA(Code Division Multiple Access) (CDMA) digital standard extensively adopts in the U.S..
GSM standard is time division multiple access (TDMA) standard, and by using distributed time slot, each user's voice data of alternate transmission in burst can make a plurality of users share the individual voice channel.The CDMA standard combines spread spectrum, can use spreading code that digitized conversation signal is cut into bit by spreading code being appended in each conversation and with a plurality of conversation digitlizations, ressembles signal then after transmission.
20th century the nineties early stage, the GSM network brings into use subscriber identification module (SIM) card to improve the radio telephone fail safe, and the authentication process that facilitates for the user.Recently, replaceable subscriber identification module (RUIM) becomes possibility, and the international roaming of allow crossing over CDMA and GSM network, allow their handheld device of customer upgrade and do not need each characteristics of reprogrammed such as their personally identifiable information and radio telephone/address book.The RUIM smart card normally comprises the little plastic clip of embedded computer chip, and this chip is used to store for example secure data, tentation data, radio telephone/address-book data, network settings and other information relevant with the special services characteristics.RUIM is detachably connected to and uses like the slot type that SIM card uses on the radio telephone usually.
Therefore, international traveler can be carried out " plasticity roaming (plasticroaming) " by spanning network now.For example, the user can be simply remove RUIM and this RUIM is put into the gsm wireless phone and roams into the GSM network from cdma network from the cdma wireless phone.Network is recognized user's network data and personal data immediately then.
Yet, and early stage RUIM version and can spanning network aspect the OTA regulation feature back compatible that is used for multi-mode radio telephone of operation, existing RUIM technology remains limited.Mobile radiotelephone regulation is related to initial configuration (being called startup) and upgrading characteristics and loads data into radio telephone.In the place of stipulating that service provider's physical access radio telephone can be used, for example the radio telephone retailer who initially sells a little, the radio telephone regulation of the wired connection of user interface or storage card may appear using.
Stipulate the disabled place of service provider's physical access radio telephone, can use the OTA regulation to upgrade radio telephone.Compare with requiring the physical access radio telephone, the OTA regulation is convenient more usually for the user.The OTA regulation further allows to advance and pull out regulation.Advancing regulation is that data are written into radio telephone automatically, and wireless telephone user and not knowing.Safety problem requires to advance regulation to only limit to for example trusted source of known service provider.
Pulling out regulation allows wireless telephone user to be written into selected radio telephone characteristics at a convenient time.For example, the user can use the Internet-browser characteristics on their radio telephone to navigate to selected webpage, stipulates their radio telephone from webpage wireless downloading radio telephone then.
Requirement comprises optimum roaming list (PRL) by some the more important data on the mobile radiotelephone that advances or draw in the regulation frequent updating.PRL is the frequency band that can use of certain network and the tabulation of channel, and when radio telephone is powered first or when radio telephone leaves scope and existing the connection when beginning to worsen, radio telephone attempts to connect described frequency band and channel.When environmental change, PRL often needs to upgrade.For example, the mobile service provider often and other providers different agreement is arranged, allow the roaming discount, so when this type of protocol changes, need upgrade PRL.Equally, the user may select to upgrade PRL based on the change of other characteristics on the change of their service agreement or the radio telephone.In addition, be written into or by its relevant RUIM being moved on to another from a radio telephone when switching handheld device, PRL needs to upgrade as the user.
PRL is stored in the nonvolatile memory on the RUIM usually.When RUIM was connected to radio telephone and opens radio telephone, radio telephone read the PRL that resides on the RUIM, be written in the memory of PRL to the radio telephone maybe with this PRL and be stored in already on the radio telephone existing PRL relatively.Then, only when upgrading, needs change existing PRL.
Yet original PRL is designed for single wireless access technology usually.When the user attempted to use the earlier version of RUIM card in the multi-mode radio telephone, compatibling problem had appearred in the multi-mode radio telephone that comprise the dual-mode wireless phone, can cross over the operation of a plurality of wireless access technologys.When tradition or legacy version RUIM be inserted in the multi-mode radio telephone and because RUIM to go up storage not enough and can not be updated the time, another compatibling problem has also occurred.Equally, when having upgraded tradition or legacy version RUIM with redaction PRL, when it was inserted into conventional wireless phone again, because incompatibility backward, tradition or legacy version radio telephone can not be recognized and upgraded RUIM.Yet, still wish when customer upgrade during, when the user wants can allow the user to use and have traditional RUIM card now when upgrading traditional RUIM card and insert traditional radio telephone again to multi-mode radio telephone.Therefore, need improved method and system, allow traditional RUIM card, upgrade traditional RUIM card, the wireless telephonic whole compatibilities of newer multi-mode radio telephone and older monotype.
