Quantity according to LTE network in the practical application, PRL file in CDMA CSIM/RUIM subscriber card adds the SystemRecord clauses and subclauses of the PLMN numbering of several expressions LTE network, each System Record clauses and subclauses comprises the PLMN numbering, and its ACQ_INDEX is according to one of 4 newly-increased in the business setting Compass 2 Acquisition Record clauses and subclauses.
According to the present invention is based on that PRL inserts example of method of LTE network and unrestricted, the LTE terminal according to PLMN tabulation carry out the LTE network insertion and specifically can realize in the following manner:
Whether the target P LMN attribute in the LTE terminal recognition PLMN tabulation is forbidding PLMN;
If forbidding PLMN, the LTE terminal is returned and is begun to carry out the operation that search network inserts message;
Otherwise if HPLMN, UPLMNs or OPLMNs, the LTE accessing terminal to network inserts the corresponding LTE network of PLMN numbering in the message.
Exemplarily, the corresponding LTE network of PLMN numbering specifically can be realized in the following way in the LTE accessing terminal to network access message:
The LTE terminal is the corresponding LTE network registry of PLMN numbering in the described network insertion message, and after successful registration, inserts the PLMN of corresponding PLMN tabulation expression;
If returning, not successfully registration, LTE terminal carry out the operation that search network inserts message;
If the LTE network of network priority level that success is registered is not high enough, for example, is not the HPLMN grade, return the operation of carrying out search network access message according to predetermined period, to seek the higher LTE network of network priority level.
Wherein, the network priority level reduces successively according to the order of HPLMN, UPLMNs, OPLMNs and forbidding PLMNs, and forbidding PLMNs represents that current LTE terminal use forbids inserting the LTE network that this forbidding PLMNs represents.
If the CDMA terminal reads the System Record clauses and subclauses that relate to the LTE network, because the Acquisition Record clauses and subclauses that SYS_RECORD_TYPE wherein and ACQ_INDEX point to are the reserved field of CDMA definition, so by the CDMA terminal disregards, do not go to read.
