Abstract
The present disclosure discloses systems and methods for providing continuous Multimedia Broadcast Multicast Service (MBMS) and unicast services during mobility. On detecting mobility from a first cell to a second cell, the User Equipment (UE) receives system information and a preamble transmission signal. A System Information (SI) time window is determined from the system information and a Random-Access Response (RAR) window is determined using the preamble transmission signal. The UE performs either an SI-Radio Network Temporary Identifier (SI-RNTI) decode on System Information Block Type 2 (SIB2) during the SI time window or a Random Access (RA)-RNTI decode during the RAR window. Subsequently, the UE decodes MBMS-RNTI (M-RNTI) before and after the selected window based on an MBMS configuration received from the first cell. Thereafter, the UE receives a Multimedia Broadcast Single Frequency Network (MBSFN) configuration for the second cell, which is enables uninterrupted MBMS and unicast services.
