Abstract
The invention discloses an extensional updating method and a terminal for accessing inhibit control information and aims to achieve quick updating of embedded array block (EAB) information. The method includes the following steps: the terminal records that updating exists in the EAB information when receiving updating instructions of the EAB information; the terminal judges whether the EAB information has an updating record when the terminal is ready to start an accessing request, and if the updating record of the EAB information exists, the updated EAB information is read. The terminal comprises a receiving module, a recording module, a judging module and a reading module. The updating mechanism can avoid influences on a common terminal because of updating of an EAB; and in addition, when the EAB information is updated repeatedly, the terminals which do not start accessing do not need to be updated every time and only need to read the newest EAB information before accessing and use the EAB information into an accessing process, and therefore power consumption of the terminals is reduced.

In universal mobile telecommunications system (UMTS, Universal Mobile TelecommunicationsSystem), subscriber equipment can be divided into 16 access grade (AC, Access Class), wherein, AC 0～9 belongs to common grade, and Random assignment is to terminal; AC 10 expression urgent calls (can not configure to terminal); AC 11 is used for network operation; AC 12 is safety service; AC 13 is public service classification (as water, gas supplier); AC 14 expression urgency traffics; The AC 15 expression staff of operator.Terminal can be configured to rank in AC0-9 and the one or more ranks in AC11-15, and these configuration informations are kept in Subscriber Identity Module (USIM, Universal Subscriber IdentityModule).
Network side broadcast system message in UMTS comprises access grade and forbids (ACB, Access ClassBarred) parameter, for common access grade AC 0～9, ACB corresponding to network side broadcasting is configured to enumeration type (can be configured to forbid (barred) or allow (not barred)), come to 10 bit, adopt the mode difference corresponding A C 0～9 of bitmap images (bitmap).If need initiating business request, whether the ACB parameter that at first subscriber equipment needs to check the Cell Broadcast CB that accesses forbids (barred) AC under self, if forbid, subscriber equipment can not initiating business request; If do not forbid, subscriber equipment can initiating business request.
In addition, UMTS has also introduced access service grade (ASC, Access Service Classes) concept is exactly that Access Network is used for Random Access Channel (RACH, Random Access Channel) resource distribution and access probability and some grades of arranging.UMTS configuration AC 0-9 and each grade mapping of AC10-15 are to each grade of ASC, and ASC is totally 8 grades, difference ASC 0-7, and wherein, ASC0 priority is the highest, and ASC7 priority is minimum, for different ASC grades, has preset different RACH resources; The lasting factor (persistence value) of the ASC that terminal is corresponding according to self AC and the random 0-1 random number that produces judge whether to access UMTS.
Long Term Evolution (LTE, Long Term Evolution) network side in system also can be broadcasted the ACB parameter, terminal for AC 0～9, network side broadcasting access scale factor (ac-BarringFactor) and access barred time (ac-BarringTime), ac-BarringFactor is used for controlling the probability of subscriber equipment access network.UE produces equally distributed random number (RAND) between 0 to 1 at random when the needs initiating business request, if this RAND lower than the access scale factor, UE can initiating business request; Otherwise UE can not initiating business request, and UE will calculate a time of delay according to ac-BarringTime, does not allow again to access for same service request within this time of delay.
In the LTE system, the control parameter that ACB is relevant (access scale factor and access barred time) is carried in system information SIB2, when its content changed, carrying out also according to the general system information update mechanism of LTE system, notification terminal upgraded.Detailed process is: the updating system information content must just can be carried out when the predefined system information modification cycle arrives; Change by beep-page message (Paging) notification terminal system information, terminal reads whole system informations, the ACB parameter after obtaining to upgrade.
