Different Categories of UE in LTE Categories of UE in LTE is divided by its function which is as per below. Functionality: eNB obtains the UE radio capabilities via: • The S1AP initial setup request message • The X2AP in case of handover • The RRC in any other cases eNB sends the UE radio … Read more
In LTE (Long-Term Evolution), handover measurements are crucial for ensuring seamless mobility as User Equipment (UE) moves across different cells within the network. These measurements assist in deciding when and to which cell a handover should occur. Here’s an overview of key handover measurements in LTE: Received Signal Strength (RSS): RSS measures the power level … Read more
The UE is RRC connected. During the HO: The radio link is released from the eNodeB 1 and re-established on the eNodeB 2 The Control plane is switched to the eNodeB 2 and the MME The User plane is switched to the eNodeB 2 and the S-GW The Intra-e-UTRAN-Access Mobility Support for UEs in ECM-CONNECTED … Read more
In the C-plane, the NAS functional block is used for network attachment, authentication, setting up bearers, and mobility management. All NAS messages are ciphered and integrity protected by the MMEand UE. The radio resource control (RRC) layer in the eNB makes handover decisions based on neighbor cell measurements reported by the UE, performs paging of … Read more
If the IE “Filter coefficient” is received the UE applies filtering of the measurements for that measurement quantity according to the formula below. This filtering is performed by the UE before UE event evaluation. The UE filters also the measurements reported in the IE “Measured results”. The filtering is performed according to the following formula: … Read more
The development of the simulator that will be implemented can be classified in two phases. The first phase is the development of a simulator, capable for the investigation of the typical handover procedure. The second phase will include the implementation of the LAH algorithm that will consider the location of the user. Simulations that will … Read more
