COMMUNICATION METHOD, USER EQUIPMENT, AND BASE STATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18431744 titled 'COMMUNICATION METHOD, USER EQUIPMENT, AND BASE STATION
Simplified Explanation
The communication method described in the abstract is used in a mobile communication system to support a multicast and broadcast service (MBS). It involves managing PDCP variables in user equipment and synchronizing them with base station variables in response to interruptions in MBS session reception.
- Explanation of the patent/innovation:
- User equipment manages a first PDCP variable in response to receiving PDCP packets in an MBS session. - User equipment synchronizes the first PDCP variable with a second PDCP variable managed by the base station when MBS session reception is interrupted for a predetermined time.
Potential applications of this technology: - Mobile communication systems - Multicast and broadcast services - Synchronization of PDCP variables in wireless networks
Problems solved by this technology: - Efficient management and synchronization of PDCP variables in MBS sessions - Improved reliability of data transmission in mobile communication systems
Benefits of this technology: - Enhanced performance of multicast and broadcast services - Reduced interruptions in MBS session reception - Better user experience in mobile communication systems
Potential commercial applications of this technology: - Mobile network operators - Telecommunication equipment manufacturers - Providers of multicast and broadcast services
Possible prior art: - Prior art related to PDCP variable management and synchronization in mobile communication systems - Research on multicast and broadcast services in wireless networks
Questions: 1. How does this communication method improve the efficiency of multicast and broadcast services in mobile communication systems? 2. What are the specific technical challenges involved in synchronizing PDCP variables between user equipment and base stations during interruptions in MBS session reception?
Original Abstract Submitted
In a first aspect, a communication method is a communication method used in a mobile communication system for supporting a multicast and broadcast service (MBS). The communication method includes: managing, by a user equipment having started reception of an MBS session from a base station, a first Packet Data Convergence Protocol (PDCP) variable updated in response to reception of a PDCP packet in the MBS session, the first PDCP variable being managed in a PDCP layer; and performing, by the user equipment, control of synchronizing the first PDCP variable with a second PDCP variable managed by the base station, in response to determining that the reception of the MBS session has been interrupted for a predetermined time.
