Description
Technical Field
The present invention relates to a parameter transfer method in a wireless communication system, and more particularly, to a method for discontinuous transmission and discontinuous reception parameters of a continuous packet connection.
Background
In order to reduce the transmission delay of packet domain data, the 3GPP protocol standard evolves the protocol architecture of the third generation mobile communication, i.e. the Radio Network Controller (RNC) moves down to the node B (nodeb), which has the functions of serving the radio network controller, controlling the radio network controller, and drifting the radio network controller, and this node B may be referred to as an enhanced node B for short.
The downward shift of the radio network controller causes the interface definition between different nodes to change, an Iur interface is adopted between the enhanced node B and the enhanced node B, an Iur interface is also adopted between the enhanced node B and the traditional Radio Network Controller (RNC), an Iu interface is adopted between the enhanced node B and the core network node, and only the Iu interface of the packet domain is supported.
In the current protocol, for the relocation process, the source wireless access network system needs to send out information through a ' relocation requirement ' signaling carried by a ' transparent container ' from a ' source wireless network controller to a target wireless network controller, and then transparently forwards the information to the target wireless access network system through a ' relocation request ' signaling carried by a core network for use by the target wireless access network system. The "transparent container from the source radio network controller to the target radio network controller" does not contain information of the physical channel, that is, after the target radio access network controller receives the relocation request, the target radio access network controller needs to reconfigure the parameters of the physical layer according to the resource allocation condition of the target radio access network controller.
Based on the architecture shown in FIG. 1, the following scenarios require relocation to occur:
(1) RRC connection is established between the user equipment and the enhanced node B or the service of the packet domain exists, but the subsequent user equipment calls the service of the circuit domain, so the enhanced node B needs to initiate the relocation process;
(2) the user equipment has the concurrence of circuit domain and packet domain services, so that the control right of the user equipment is in the traditional radio network controller RNC, but along with the release of the circuit domain services, the traditional RNC needs to initiate a relocation process to the enhanced node B because of load balancing;
(3) when the enhanced node B is used as a serving node B of a ue, the serving node B generally has the best signal strength, and has the function of serving RNC and the function of combining uplink packet data, but due to the movement of the ue, the serving node B needs to make frequent updates, and then the function of the serving RNC needs to be frequently transferred, so that a frequent relocation process is also needed.
Then, based on the new architecture that a Radio Network Controller (RNC) is moved down to a node B (node B), a deployed network may have an enhanced node B that is a node B with a carrier frequency shared by a circuit domain and a packet domain, that is, a service of the circuit domain and a service of the packet domain may use the same radio resource pool in a cell under the control of the node B, but as long as a user equipment has a service of the circuit domain, a controller connected to the RRC is in a conventional RNC, so that there is a case that the control right of the RRC is in different nodes but only one set of physical resources exists.
In order to avoid the situation that the user equipment is communicated in the same cell but the physical resource is reconfigured due to the relocation in the above-mentioned (1) and (2) situations, the source radio access network system is required to notify the target radio access network controller (or enhanced node B) of the physical channel parameter information currently configured to the user equipment.
However, the discontinuous transmission and discontinuous reception parameters are control parameters for determining the MAC layer and the physical layer of the ue to perform discontinuous transmission and discontinuous reception, and the related parameters include:
enable Delay (enable Delay): the UE judges to enter the DTX _ DRX state to really activate the number of the wireless frames to be delayed;
discontinuous transmission discontinuous reception Offset (UE DTX DRX Offset): is used for staggering the interval time of discontinuous transmission and discontinuous reception of different user equipment;
user equipment discontinuous transmission cycle period 1(UE DTX cycle 1): discontinuous cycle period used by uplink discontinuous transmission mode 1;
user equipment discontinuous transmission cycle period 2(UE DTX cycle 2): discontinuous cycle period used by uplink discontinuous transmission mode 2;
discontinuous transmission cycle period (MAC DTX cycle) of the medium access layer: the UE enters a cycle period of E-TFC selection after entering a period selection E-TFC state;
inactivity Threshold for UE DTX cycle 2 controlled by the UE entering discontinuous transmission cycle period 2: UE enters an inactive threshold of a discontinuous transmission state controlled by UE DTXcycle 2;
user equipment discontinuous transmission long prefix length (UE DTX long preamble length): the time slot number of the DPCCH is required to be sent preferentially when the UE needs to send data after entering the discontinuous sending state controlled by the UE DTX cycle 2;
inactivity Threshold of the medium access layer (MAC Inactivity Threshold): the UE enters an MAC non-activation threshold for carrying out E-TFC selection periodically every MAC DTX cycle subframes;
channel quality indication discontinuous transmission Timer (CQI DTX Timer): channel Quality Indication (CQI) reporting the timer length that may prioritize DTX transmission mode;
burst 1 of user equipment dedicated physical control channel (UE DPCCH burst _ 1): when UE is in discontinuous transmission state controlled by UE DTX Cycle 1, carrying out DPCCH subframe number used by wireless link synchronization;
burst 2 of the user equipment dedicated physical control channel (UE DPCCH burst _ 2): when UE is in discontinuous transmission state controlled by UE DTX Cycle 2, carrying out DPCCH subframe number used by wireless link synchronization;
user equipment discontinuous reception cycle (UE DRX cycle): the UE monitors a cycle period of a control channel (HS-SCCH) for a high-speed physical downlink shared channel;
inactivity Threshold for ue drx cycle for user equipment entering discontinuous reception: UE switches to the period of every UE DRX cycle subframe to monitor the non-activation threshold of the HS-SCCH state;
inactivity Threshold for ue authorization Monitoring (Inactivity Threshold for ue grant Monitoring): after data transmission on an E-DCH, UE needs to monitor an inactive threshold of a complete reinforcement absolute grant channel (E-AGCH) of a service reinforcement dedicated channel (E-DCH) cell and a complete reinforcement relative grant channel (E-RGCH) of an E-DCH active set;
grant Monitoring of discontinuous reception by the user equipment (UE DRX Grant Monitoring): when the starting of discontinuous reception of the E-AGCH, the E-RGCH and the HS-SCCH is overlapped, indicating whether the UE monitors a complete E-AGCH channel of an E-DCH service cell;
slot format information (Uplink DPCCH slot format information) of the dedicated physical control channel for Uplink connection.
These parameters all belong to physical channel parameters, so in order to ensure data connectivity between the user equipment and the target radio access network, the source radio access network also needs to notify the target radio access network of the parameters of discontinuous transmission and discontinuous reception.
