Abstract
The invention provides a method for searching a network, as well as a device and an SIM card thereof. The method comprises the following steps: retrieving the corresponding relation between illegal HPLMN number and legal HPLMN number which are stored in the SIM card when home public land mobile network HPLMN number is used for searching the network; and initiating the network search by the corresponding legal HPLMN number if the matching legal HPLMN number is found. In the method, the corresponding relation between the illegal HPLMN number and the legal HPLMN number is stored in the SIM card, and the technical means of searching the network by the legal HPLMN number is used, which overcomes the problem of slow network search speed, thus further achieving the technical effects of reducing unnecessary network search expenditure and quickening the network search speed.
Description
Technical field
The present invention relates to moving communicating field, relate in particular to a kind of method, device and SIM card of searching net.
Background technology
It is as follows that mobile phone is searched the net flow process: behind the mobile phone power-on, at first can activate SIM card, read and search the necessary parameter of net.Deposit the file (LOCI file) of searching the net lastest imformation in the SIM card, the inside has comprised the net information of searching (network No. that landed last time, update mode) of last time.Wherein, update mode is divided 3 kinds: U1: upgrade (UPDATED), represent that the process of last position renewal has been finished, and receive sure the replying of network side; U2: upgrade (NOT UPDATED), represent that the process of last position renewal is not finished, do not receive replying of network side; U3: do not allow roaming (ROAMING NOT ALLOWED), represent that the process of last position renewal has been finished, but receive negative the replying of network side.
If the position update mode of SIM card is UPDATED, and the net that landed last time is not ownership public land mobile communication network (HPLMN), and then the net that will land last time is as the net that will go up of start.If the position update mode of SIM card is not UPDATED, perhaps the position update mode of SIM card is UPDATED, and the net that landed last time is HPLMN, and then attempt to go up HPLMN: after determining network No., mobile phone begins to search for proper cell, and lands up.Initiate position updating request afterwards, wait for the network side response.After upgrading successfully, with network No., updating mark writes the LOCI file of SIM card, has got the inferior net of searching ready and has used.
In realizing process of the present invention, the inventor finds that there are the following problems at least in the prior art: because cellphone subscriber's quick growth, a mobile subscriber of global range unique identification (IMSI) number section is more and more not enough, and operator has to expand.So such batch card occurred, preceding 5 of IMSI (generally represent this card HPLMN number) may comprise one and not have network No. (be called illegal HPLMN number, otherwise, be called legal HPLMN number).Start shooting first at mobile phone, when carrying out cell selecting, must all judge the network No. on 40 frequencies nearly that search out one time, very time-consuming, cause inserting the mobile phone of this kind card when searching net for the first time very slow (not waiting in 3-5 minute), it is very slow perhaps to search net under abnormal conditions (sudden power when searching net causes SIM card not have enough time to upgrade the LOCI file).
Summary of the invention
Embodiments of the invention are to search the slow problem of net in order to solve mobile phone, on the one hand, the embodiment of the invention provides a kind of method of searching net, described method comprises: when using the ownership public land mobile communication network to search net for HPLMN number, preserve in the retrieving SIM card illegal HPLMN number with legal HPLMN number corresponding relation; If when retrieving the legal HPLMN of coupling, utilize and initiate to search net corresponding described legal HPLMN number.
On the other hand, the embodiment of the invention provides a kind of device of searching net, and described device comprises: the corresponding relation retrieval unit, be used for when using when searching net for HPLMN number, preserve in the retrieving SIM card illegal HPLMN number with legal HPLMN number corresponding relation; Search net and initiate the unit, when being used to retrieve the legal HPLMN of coupling, utilizing and initiate to search net corresponding described legal HPLMN number.
On the other hand, the embodiment of the invention also provides a kind of SIM card, and described SIM card comprises the above-mentioned device of searching net.
Technique scheme has following beneficial effect: because adopt the illegal HPLMN number corresponding relation with legal HPLMN number is saved in the SIM card, and utilize the technological means of searching net legal HPLMN number, so overcome the slow problem of net of searching, and then reached the expense that reduces unnecessary search network, accelerate to search the technique effect of net spee.
