Abstract
The invention relates to the mobile communication technical field, and discloses a transferring method for reducing high-speed downlink sharing control channel load parameters. When a position is relocated, an active wireless access network system transmits a sharing control channel load parameter used for reducing the high speed downlink channel to a target wireless access network system through the carrying of a signaling. The parameter can be transmitted directly or forwarded through the way that core network carries the parameter transparently to the target wireless access network system. During transmission, A wireless resource controller container of sharing control channel load parameter used for reducing the high speed downlink channel is added to 'a transparent container from the active wireless network controller to the target wireless network controller' of the signaling. When the relocation is needed, the invention can immediately transmit sharing control channel load parameter used for reducing the high speed downlink channel to the target wireless access network system from the active wireless network access system, so as to ensure that data continuity of user equipment and the target wireless access network.
Description
Technical field
The present invention relates to the mobile communication technology field, relate in particular to and transmit the method that is used to reduce the load of high-speed downlink shared control channel parameter in a kind of wireless communication system.
Background technology
In order to reduce the propagation delay time of block domain data, the 3GPP consensus standard has carried out evolution to the protocol infrastructure of 3G (Third Generation) Moblie, also be that radio network controller (RNC) moves down into Node B (NODEB), Node B has the function of service wireless network controller, control radio network controller, floating radio network controller, and this Node B can abbreviate reinforced Node B as.
Moving down of radio network controller, make the interface definition between the different nodes that variation also take place, adopt the Iur interface between reinforced Node B and the reinforced Node B, also adopt the Iur interface between reinforced Node B and the traditional radio network controller (RNC), adopt the Iu interface between reinforced Node B and the core net node, and only support the Iu interface of packet domain.
Existing protocol is for repositioning process at present, its source wireless access network system need carry and send by " reorientation demand " signaling by " source radio network controller is to the transparent vessel of target radio network controller " information, carry transparent forwarding to the target radio access network system via core net " re-positioning request " signaling again, use for the target radio access network system.Wherein " source radio network controller is to the transparent vessel of target radio network controller " do not comprise the information of physical channel, also be the target radio access network controller after receiving re-positioning request, need carry out reprovision to the parameter of physical layer according to the resource allocation conditions of target radio access network controller.
Based on framework shown in Figure 1, reorientation need take place in following scene:
(1) set up the business that RRC connects or exist packet domain between subscriber equipment and the reinforced Node B, but subsequent user equipment is exhaled the business in circuit passband territory again, then reinforced Node B need be initiated the process of reorientation;
(2) subscriber equipment makes its control at traditional radio network controller (RNC) because there be the concurrent of circuit domain and packet switch domain service, but along with the release of circuit domain business, because load balancing tradition RNC need initiate the process of reorientation to reinforced Node B;
(3) when reinforced Node B during as the serving node B of subscriber equipment, serving node B has best signal strength signal intensity generally speaking, it has the function of service wireless network controller RNC and ascending packet data is carried out pooling function, but because subscriber equipment is mobile, cause serving node B need do frequent renewal, the function of Serving RNC is also wanted frequent transfer so, thereby also can need the process of frequent generation reorientation.
Move down into the framework of Node B (NODE B) so based on new radio network controller (RNC), it is the Node B of circuit domain and packet domain common carrier frequency that can there be reinforced Node B in the network of disposing, also be that the business of circuit domain and the business of packet domain can be used identical Radio Resource pond in the sub-district under this Node B administration, but as long as there is the business of circuit domain in subscriber equipment, then the controller of RRC connection is just at traditional RNC, the control that so just has RRC is at different nodes, but physical resource has only the situation of a cover.
Though under same sub-district, communicate by letter for fear of subscriber equipment, but cause the situation of physical resource reprovision to take place because of the reorientation of above-mentioned (1) and (2) two kinds of situations, need the source wireless access network system to notify target radio access network controller (or reinforced Node B) the current configuration to the physical channel parameters information of subscriber equipment.
Introduced the method for not using the shared control channel of high speed descending sharing channel for the load of the control channel that reduces small data flow business,, also needed to dispose relevant physical channel parameters in order to realize its function.Therefore, in order to guarantee the continuing property of data of subscriber equipment and target radio access network, the source Radio Access Network also needs to notify target radio access network with the parameter that reduces the shared control channel load of high speed descending sharing channel.Thereby, need a kind of transmission to be used to reduce the method for the shared control channel load parameter of high speed descending sharing channel.
