Embodiment 2
The embodiment of the present invention provides a kind of method of subscriber equipment access carrier converging network, be applied to carrier aggregation network as shown in Figure 1, suppose that the community in eNB coverage is the first community, this first community is main plot, the community of the micro-base station in eNB coverage is the second community, this second community is auxiliary community, and as shown in Figure 3, described method comprises:
Step 201, subscriber equipment 1 send registration request to eNB.
Subscriber equipment 1 enters the coverage of the first community and the region of the second cell coverage area overlap, because the priority of described first community is higher than the priority of described second community, subscriber equipment sends registration request to eNB, described registration request comprises the cell id of the first community, the first community is registered to for asking eNB, described first community is the community of TDD frequency range, and described second community is the community of FDD frequency range.It should be noted that, eNB can the community of this eNB of unified management, and the community of micro-base station in the coverage of this eNB.
Step 202, eNB send registration reply message to subscriber equipment 1.
Subscriber equipment 1 is registered to the first community according to registration reply message.
Step 203, subscriber equipment 1 send the first message to eNB.
Described first message comprises the ability of described subscriber equipment 1, and the ability of described subscriber equipment 1 is used to indicate described subscriber equipment 1 and supports FDD frequency range and TDD frequency range.
Step 204, eNB judge that the load value of the second community is less than or equal to threshold value.
After eNB receives the ability of this subscriber equipment 1 that subscriber equipment 1 sends, judge whether the load value of this second community residing for subscriber equipment 1 is less than or equal to threshold value.Usually, Physical Resource Block (English full name: physicalresourceblock can be passed through, English abbreviation: PRB) occupancy α judge the size of load value, more heavy load value is larger for the occupancy α of PRB, the load of little area carrier is larger, in like manner, the threshold value of load value can be just the occupancy threshold value α of PRB
th.Concrete, eNB can judge whether the occupancy α of the PRB of the second community is less than or equal to the occupancy threshold value α of PRB
th, wherein, the occupancy threshold value of PRB can be set by operator oneself, and operator can the situation that take of history PRB of reference cell set, usually, and the occupancy threshold value α of PRB
thcan 70% be set to.It should be noted that, the type of service that also can use with reference to subscriber equipment when judging the load value of community, or judge the load value of community with reference to type of service together with the occupancy of PRB.
When the load value of the second community is less than or equal to threshold value, perform step 205.When the load value of the second community is less than or equal to threshold value, illustrate that the cell load of FDD frequency range is lower, even if be switched to by subscriber equipment in the community of FDD frequency range, also can not cause too large burden to the community of FDD frequency range.
When the load value of the second community is less than or equal to threshold value, perform step 206.
Step 205, eNB send the first wireless resource control connection reconfiguration message to subscriber equipment 1.
First wireless resource control connection reconfiguration message (RadioResourceControlConnectionReconfiguration) comprises described switching instruction, and described switching instruction is used to indicate described subscriber equipment 1 and is switched to the second community.
Further, first wireless resource control connection reconfiguration message also comprises switch reasons field (handovercause), described switch reasons field is the field newly increased in the first wireless resource control connection reconfiguration message, and this switch reasons field is arranged in mobile control information (MobilityControlInfo) field of described first wireless resource control connection reconfiguration message.When switch reasons field is set to " 1 ", instruction return back to carrier aggregation state; When switch reasons field is set to " 0 ", indicating other to switch, is not namely need to carry out the switching that carrier aggregation causes, but the switching caused by other reasons.
Step 206, eNB send to subscriber equipment 1 and continue the resident instruction to the first community.
Step 207, subscriber equipment 1 are switched to the second community.
The idiographic flow that subscriber equipment 1 is switched to the second community with reference to the switching flow in LTE, can not repeat them here.
Step 208, eNB send the second wireless resource control connection reconfiguration message to subscriber equipment 1.
Described second wireless resource control connection reconfiguration message is used to indicate the first community described in described user device configuration.
Step 209, subscriber equipment 1 are according to the second wireless resource control connection reconfiguration message arrangement first community.
Subscriber equipment 1 is according to the second wireless resource control connection reconfiguration message arrangement first community, and send the second wireless resource control connection reconfiguration to eNB and complete message, eNB activates the first community.
Relative to prior art, when subscriber equipment is resident on the community of TDD frequency range, when using TDD as main carrier, Internet resources cannot be effectively utilized to improve transmission rate.The present invention is according to the ability of this subscriber equipment of user equipment to report, described subscriber equipment is indicated to support FDD frequency range and TDD frequency range, and when judging that the load value of community of FDD frequency range at this subscriber equipment place is less than or equal to threshold value, send to described subscriber equipment and switch instruction, described subscriber equipment is indicated to be switched to the community of FDD frequency range, configuration messages is sent again to described subscriber equipment, indicate the community of described user device configuration TDD frequency range, thus make subscriber equipment be in carrier aggregation state, make subscriber equipment that TDD carrier wave and FDD carrier wave can be used to come together to transmit data, Internet resources can be effectively utilized to improve transmission rate.
Especially, if subscriber equipment is in the coverage of the community of eNB, and in the coverage of at least community of the micro-base station of two or more, the signal quality of this subscriber equipment to each micro-base station first measured by subscriber equipment, the community of a best micro-base station of signal quality is selected to register.And then perform step 203 to step 209.
