Method of transmitting and receiving paging messages in a wireless communication system
View Patent ↗A method of transmitting and receiving paging messages in a wireless communication system is disclosed. The method of transmitting paging messages in a wireless communication system comprises transmitting paging messages to a plurality of user equipments from a network of the wireless communication system, wherein the network transmits the paging messages to different user equipments, which are in different connection states, through different channels.
1. A method of transmitting a paging message from a network to a user equipment in a wireless communication network, the method comprising:
receiving capability indication information from the user equipment which is able to receive paging messages through a high speed downlink physical shared channel (HS-PDSCH), the capability indication information indicating that the user equipment is able to receive a paging message on the high speed downlink physical shared channel in a PCH state;
transmitting an HS-SCCH control message on a high speed shared control channel (HS-SCCH) to the user equipment, the HS-SCCH control message comprising an HS-DSCH radio network identifier (H-RNTI) that corresponds to the user equipment; and
transmitting the paging message to the user equipment on the HS-PDSCH using the control message.
2. The method of claim 1 , wherein the PCH state is a state in which information can be transmitted and received between specific protocol layers of the network and the user equipment.
3. The method of claim 2 , wherein the specific protocol layers are radio resource control (RRC) layers.
4. The method of claim 1 , further comprising transmitting paging indication information to the user equipment on a paging indication channel (PICH).
5. The method of claim 1 , wherein the capability indication information is received through a radio resource control (RRC) connection request message or in an RRC connection complete message.
6. The method of claim 1 , further comprising transmitting the paging message on a secondary common control channel (S-CCPCH) to which a paging channel is mapped.
7. A network device for transmitting a paging message to a user equipment in a wireless communication network, the network entity comprising:
a receiver adapted to receive capability indication information from the user equipment which is able to receive paging messages through a high speed downlink physical shared channel (HS-PDSCH), the capability indication information indicating that the user equipment is able to receive a paging message on the high speed downlink physical shared channel in a PCH state; and
a transmitter adapted to transmit an HS-SCCH control message on a high speed shared control channel (HS-SCCH) to the user equipment, the HS-SCCH control message comprising an HS-DSCH radio network identifier (H-RNTI) that corresponds to the user equipment, the transmitter further adapted to transmit the paging message to the user equipment on the HS-PDSCH using the control message.
8. The network device of claim 7 , wherein the PCH state is a state in which information can be transmitted and received between specific protocol layers of the network and the user equipment.
9. The network device of claim 8 , wherein the specific protocol layers are radio resource control (RRC) layers.
10. The network device of claim 7 , wherein the transmitter is further adapted to transmit paging indication information to the user equipment on a paging indication channel (PICH).
11. The network device of claim 7 , wherein the capability indication information is received through a radio resource control (RRC) connection request message or in an RRC connection complete message.
12. The network device of claim 7 , wherein the transmitter is further adapted to transmit the paging message on a secondary common control channel (S-CCPCH) to which a paging channel is mapped.
