AI Technical Summary

Technical Problem

Conventional multicast and broadcast services (MBMS) in wireless communication systems face service connection and continuity issues when a user equipment (UE) moves from one multicast transmission single frequency network (MBSFN) to another, requiring disruptive handovers that involve disconnecting and reconnecting to new cells.

Method used

A method where a UE receives hints or pointers in the data from a serving cell within an MBSFN, indicating the location of the MBMS control channel (MCCH) or system information block (SIB) in a target MBSFN, allowing seamless handovers without the need to re-acquire these signals upon entering the new MBSFN coverage.

Benefits of technology

Enables efficient and uninterrupted continuation of MBMS services by allowing the UE to start receiving data without delay upon entering the new MBSFN, reducing service disruptions and improving handover efficiency.

Abstract

Method for providing a service among multiple multicast single-frequency network (MBSFN) multicast transmission networks, wherein each MBSFN contains one or more cells, while a user device (UE) of a wireless communication system receives a transmission service in a serving cell of the one or more cells in one of the MBSFNs, the method comprising: storing a hint in data to be transmitted by a base station corresponding to the serving cell in a first of the MBSFNs, wherein the hint is stored in a multimedia transmission multicast service (MBMS) control channel (MCCH) of the first MBSFN and either points to a carrier position of the MCCH or MBMS data in a second of the MBSFNs, or the hint is stored in a system information block of the first MBSFN and points to the carrier position of the MCCH in the second MBSFN, or the carrier position of the MCCH in the first and the second MBSFNs;and transmission of the data by the base station for the first MBSFN to be received by the UE.;
