Inter-RAT Cell Reselection from GSM to UMTS

When MS in a GSM cell obtain the list of neighboring UMTS cells and cell reselection parameters through System Information 2ter and System Information 2Quater. Based on the list and parameters, the MS measures the neighboring UMTS cells. When the MS is in idle mode or packet transfer mode, the method for cell reselection from a GSM cell to the UMTS cell is the same as that between GSM cells. The GSM network controls the cell reselection from the GSM cell to a UMTS cell through TDD Cell Reselect Diversity.

TDD Cell Reselect Diversity indicates the signal strength difference between candidate UMTS cells and the serving GSM cell. This parameter is a key factor for controlling the cell reselection from the GSM cell to the UMTS cell.

CPICH RSCP > RLA_C + TDD Cell Reselect Diversity

When TDD Cell Reselect Diversity is set to a small value, the cell reselection condition is easy to meet. In this case, the number of MSs that camp on the GSM cell reduces. When TDD Cell

Reselect Diversity is set to a great value; the cell reselection condition is difficult to meet. In this case, the number of MSs that camp on the GSM cell is increases.

EPS Network Identifier in LTE

Mobile country code (MCC) is a 3 digit code, assigned by international telecom union to identify a country in a mobile communication.

Mobile network code (MNC) is a 2 to 3 digit code, assigned by national authority.

Public land mobile network identity (PLMN Id) consists of MCC and MNC. It is used for unique identification of a PLMN.

Tracking area identity (TAI) is globally unique and consists of PLMN id and tracking area code (TAC) where TAC is of 16 bits and it is used to indicate eNB to which Tracking Area the eNB belongs  and it is unique within a PLMN. It is similar to location area identity (LAI) in GSM.

International Mobile Subscriber Identity (IMSI) consists of PLMN id and Mobile subscriber identification number (MSIN). It is unique identification of mobile (LTE) subscriber and not more than 15 digits.

MME temporary Mobile Subscriber Identity (M-TMSI) is unique within MME and assigned by the operator. It is of 32 bits.

SAE Temporary Mobile Subscriber Identity (S-TMSI) consists of MME code and M-TMSI and is used to locally identify a UE in short within a MME group (Unique within a MME Pool).It is of 40 bits.

Globally Unique MME Identity (GUMMEI) consists of PLMN id, MME group id and MME code. It is used to identify a MME uniquely in global and is not more than 48 bits.

Globally Unique Temporary UE Identity (GUTI) consists of GUMMEI and M-TMSI. It is used to identify a UE between the UE and the MME on behalf of IMSI for security reason and is not more than 80 bits.
