Technical Examples
- A paging system and method for use in a multimedia/broadcast multicast service (MBMS). The paging system checks a paging indicator channel of a UE (User Equipment), and determines whether there is a paging signal associated with a broadcast service. If the paging signal associated with the broadcast service is detected, the paging system recognizes the channel information indicative of the paging fact, checks paging information included in an ID for differentiating between the broadcast service and other broadcast services and a paging response indicator adapted to determine a transmission channel scheme of the broadcast service, establishes a radio link, and receives control information using the radio link. The base station controller adapted to manage a cell including the UE transmits MBMS transmission scheme information to the UE in advance using the paging information, resulting in maximum use efficiency of RRC (Radio Resource Controller) resources.
- A system and methods of global paging of mobile stations in a wireless network. The system includes a MSC pool (50) for servicing mobile stations within a specified service area of the network and a radio configuration database (70) defining a plurality of global paging areas (80, 82, 84) within the specified service area. The radio configuration database (70) is accessible by any mobile switching center (52, 54, 56) in the pool (50) to allow paging of a mobile station (28) roaming within the specified service area according to one or more global paging areas (80, 82, 84). The radio configuration database (70) can be structured in a hierarchy including cells, locations areas, and base station controller/radio network controller (20) for each global paging area in the specified service area. In this way, any mobile switching center in the pool is capable of paging a mobile station within the specified service area by accessing the radio configuration database and determining the cell identity, location area identity, and base station controller/radio network controller identity of a mobile station roaming within the specified service area.
- A radio system comprising a switching and management infrastructure arranged to deliver voice and data between a plurality of communicating parties, and a mobile station. Said radio system comprises a multiplicity of traffic channels, each traffic channel being associated with a unique coding scheme. The switching and management infrastructure is arranged to receive a plurality of paging messages from a plurality of communicating parties, and to combine the paging messages received during a pre-defined time period into a paging frame comprising a multiplicity of address data blocks for identifying the mobile station(s) for which the paging frame comprises a paging message. At least one of the traffic channels of the radio system is dedicated to delivery of downlink paging messages, and associated with a coding scheme that comprises at least one error protection algorithm. The mobile stations are arranged to receive data on said traffic channel, and to extract information addressed to them based on the address blocks of the paging frame.
- A method of paging a plurality of users by synchronizing user equipment (UE) specific paging and Point-to-Multipoint (PtM) user group paging to reduce power consumption when the UE is in a discontinuous reception state. The UE identities are defined such that paging occasions and common paging channels are synchronized for multiple users within a PtM user group.
- A wireless communication system implements wireless communications between a base station and a plurality of User Equipments (UEs) including paging of UEs by initially processing paging indicator information. A first embodiment involves a UE's physical layer L1 being configured for interpreting a paging indicator (PI) to activate a preset decoding configuration to process paging data in a pre-specified paging channel (PCH). A second embodiment involves the physical layer control of a next higher level, L2, interpreting the paging indicator and configuring the physical layer L1 to process paging data in a pre-specified PCH.
