Table 1 RNC Command MOD RNCBASIC (Modifying PLMN)

Parameters to be analyzed and adjusted in the access procedure MML Para mete r ID RncId RNC ID Value range: 0~4095 Physical unit: None Meaning: It is the unique identifier of an RNC. Recommended value: None Value range: 0~999 Physical unit: None Meaning: Mobile country code of RNC Recommended value: None Value range: 0~999 or 0~99 Physical unit: None Meaning: Mobile network code of RNC Recommended value: None Value range: CS_DOMAIN(CS domain), PS_DOMAIN (PS domain) Physical unit: None Meaning: It specifies the CN type Recommended value: None Value range: 0~255 Physical unit: 6min Meaning: This parameter indicates the timer length for periodical update. Periodical update is implemented by the MS through location update. The value of 0 indicates period update is not adopted. Only when the CN domain ID is CS_DOMAIN will this parameter be valid. Recommended value: 1 Value range: NOT_ALLOWED, ALLOWED Physical unit: None Meaning: This parameter indicates whether to allow attach or detach, NOT_ALLOWED indicates MS cannot apply IMSI attach and detach procedure, ALLOWED indicates the MS can apply the IMSI attach and detach procedure. This parameter is valid only when CN domain ID is set to CS_DOMAIN. Recommended value: ALLOWED Paramet er name Parameter description

Value range: MODE1, MODE2 Physical unit: None Meaning: This parameter indicates the operation network mode. It is to be set according to the actual configurations of the network. It is to be set to MODE1 if Gs interface exists between SGSN and MSC/VLR, and it is to be set to MODE2 if Gs interface does not exist between SGSN and MSC/VLR. Recommended value: None Value range: 6~9 Physical unit: None Meaning: This parameter is used by the UE to calculate the length of the DRX cycle length of the CN domain. Recommended value: 8 Value range: D100, D200, D400, D600, D800, D1000, D1200, D1400, D1600, D1800, D2000, D3000, D4000, D6000, D8000 Physical value range: 100, 200, 400, 600, 800, 1000, 1200, 1400, 1600, 1800, 2000, 3000, 4000, 6000, 8000 Physical unit: ms Meaning: The UE starts the timer T300 after transmitting the RRC CONNECTION REQUEST message, and this timer after receiving the RRC CONNECTION SETUP message. Once the timer expires, and if V300=
