Description
Technical Field
The invention relates to the technical field of mobile communication, in particular to a method for transmitting load parameters for reducing a high-speed downlink shared control channel in a wireless communication system.
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.
In order to reduce the load of the control channel of the small data traffic, a method of sharing the control channel without using the high-speed downlink shared channel is introduced, and in order to realize the function, related physical channel parameters also need to be configured. Therefore, 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 a parameter for reducing the load of the shared control channel of the high speed downlink shared channel. Thus, there is a need for a method of communicating a shared control channel loading parameter for reducing a high speed downlink shared channel.
