Step 31: network side determines whether to accept the request that this Carrier State upgrades;
Step 32: network side, determining after the request of accepting this Carrier State renewal, is carried out the operation of carrier activation or carrier wave deexcitation according to this request.
Concrete, in step 30, the request that the Carrier State that network side receiving terminal sends upgrades, specifically can be as follows:
The MAC CE that network side receiving terminal sends carries the solicited message that Carrier State upgrades in the reserved field of this MAC CE, such as, be set at 1 o'clock at this reserved field, represent the request of carrier activation, be set at 0 o'clock at this reserved field, represent the request of carrier wave deexcitation; Or,

Here, this MAC CE can be Power Headroom MAC CE, or Extended PowerHeadroom MAC CE.
Concrete, in step 31, network side determines whether to accept the request that described Carrier State upgrades, and specific implementation can be as follows:
If the request that the request that Carrier State upgrades is carrier activation, network side determines whether to exist configuration to this terminal and unactivated carrier wave according to the carrier configuration information of this terminal, if so, accepts the request of this carrier activation; Otherwise, do not accept the request of this carrier activation;
If the request that Carrier State upgrades is the request of carrier wave deexcitation, network side determines whether to exist the carrier wave of configuration to this terminal and activation according to the carrier configuration information of this terminal, if so, accepts the request of this carrier wave deexcitation; Otherwise, do not accept the request of this carrier wave deexcitation.

Below the present invention is specifically described:
In the present embodiment, by terminal according to real experiences own to service scenario or equipment situation (as the actual QoS such as service data transmission rate, packet delay index, the impression of user to business, and equipment dump energy etc.), trigger activation or the deexcitation of carrier wave, the request of the activation of carrier wave or deexcitation is notified to network equipment, the network equipment here comprises wireless access network node (the E-UTRAN NodeB of evolution, eNB), wireless access network home (e) node of trunking (Relay) and evolution (Home E-UTRANNodeB, HeNB) etc.Network equipment is received after request, carries out carrier activation or deexcitation judgement according to this request, if can meet user's request according to existing situation, judges successfully, carries out activation or the deactivating operation of carrier wave; If can not meet user's request, can not carry out activation or the deactivating operation of carrier wave.In LTE-A system, the activation of carrier wave and deexcitation are for SCC.
The concrete implementation step of the present embodiment is as follows:
Step 1: the service scenario that terminal arrives according to real experiences or equipment situation, determine whether to meet the trigger condition of carrier activation or carrier wave deexcitation.
The trigger condition of carrier activation is generally that user is unsatisfied with current transmission service quality or current service scenario does not meet self-demand.Concrete trigger condition can be:
Terminal monitoring is less than the transmission rate request minimum of business or the transmission rate value that user sets to the average transmission rate value of business.For example: terminal is downloading movies or music, find that speed of download is too slow, wish that the carrier wave configuring by activation carrys out promoting transmission rate, completes download as early as possible.
Terminal monitoring exceedes the packet delay restriction peak of business or the packet delay value that user sets to the packet delay value of business.
Terminal monitoring exceedes predefined threshold value to the data to be transmitted amount in buffer area, may occur the situation of cache overflow packet loss.
Except foregoing description, trigger condition can also be quality of service conditions that other all terminals can be experienced or that can obtain by equipment or equipment situation.
Transmission rate request minimum obtains as follows: for GBR business, the GBR value that can be its configuration using network side is as transmission rate request minimum, for Non-GBR business, transmission rate request minimum also can configure by network side, such as the PBR value that is its configuration using network side or MinBR value are as transmission rate request minimum.If network side does not have the transmission rate parameter of configuration service, can only determine whether to meet by comparing the average transmission rate of business reality and the transmission rate value of user's setting so the trigger condition of carrier activation.
The PDB parameter that packet delay restriction peak can configure by network side obtains.
The trigger condition of carrier wave deexcitation can be equipment dump energy deficiency, lower than predefined power threshold.Terminal is wished the consumption by the carrier wave deexcitation of configuration being reduced to energy, increases equipment service time.Can also be service scenario that other all terminals can be experienced or that can obtain by equipment and equipment situation.
Step 2: terminal meets after the trigger condition of carrier activation or carrier wave deexcitation definite, sends the request of carrier activation or carrier wave deexcitation to network equipment.The method that terminal sends this request can adopt several as follows:
The first, utilize the reserved field that has MAC CE.
The carrier activation that terminal is sent or the solicited message of carrier wave deexcitation represent with 1 bit, are set to 1, represent that terminal request network side activates carrier wave for it; Be set to 0, represent that terminal request network side is its deexcitation carrier wave.By this bit information by Power Headroom MAC C E(as shown in Fig. 4 a) or Extended Power Headroom MAC CE(as shown in Figure 4 b) reserved field R send.
The second, utilize the reserved field in MAC head.
The solicited message of the carrier activation of terminal or carrier wave deexcitation is represented with 1 bit, be set to 1, represent that terminal request network side activates carrier wave for it; Be set to 0, represent that terminal request network side is its deexcitation carrier wave.This bit information is sent by the reserved field in the MAC head of MAC PDU, as the field R in Fig. 4 c-Fig. 4 e.In Fig. 4 c, the L territory of MAC head is 7 bits, and in Fig. 4 d, the L territory of MAC head is 15 bits, and in Fig. 4 e, MAC head does not comprise L territory.In practical application, can select any one the MAC head in MAC PDU to transmit, as long as network and terminal consult in advance.
Step 3: network equipment is received the carrier activation of terminal or the request of carrier wave deexcitation, determines whether and accepts this request, concrete:
In the time receiving the request of carrier activation, network equipment is checked the carrier configuration information of this terminal, if there is configuration but unactivated carrier wave, the request of the carrier activation of receiving terminal; Otherwise, ignore the request of the carrier activation of terminal.
In the time receiving the request of carrier wave deexcitation, network equipment is checked the carrier configuration information of this terminal, if the carrier wave that has configuration and activate, the carrier wave deexcitation request of receiving terminal; Otherwise the carrier wave of ignoring terminal unloads ripple activation request.
Step 4: if the request of network equipment receiving terminal in step 3 is carried out carrier activation or deexcitation carrier operation according to the content of request.
Here,, if the carrier activation request of network equipment receiving terminal in step 3, network equipment is selected suitable carrier wave and is activated from the available carrier wave of system configuration.Concrete implementation method has two kinds below:
The first, based on channel quality, the SCC that meets certain activation condition is activated.Concrete grammar is as follows, and supposing the system has configured N carrier wave for this user, and this N carrier wave not yet activates.Channel quality in this N carrier wave is met to the carrier wave imposing a condition all to be activated.The index of weighing channel quality can be RSRP, can be also RSRQ.
The second, be user configured SCC, to select a most suitable SCC to activate based on channel quality from system.Concrete grammar is as follows, and supposing the system has configured N carrier wave for certain user, and this N carrier wave not yet activates.The channel quality of comparison terminal on this N carrier wave, selects a carrier activation that channel quality is best.Same, the index of weighing channel quality can be RSRP, can be also RSRQ.
Except channel quality, can also select suitable carrier wave based on factors such as surplus yields and activate.
Network side, activating after carrier wave, changes the Carrier State of activation into activation by deexcitation, then passes through MAC layer signaling to terminal.
If the carrier wave deexcitation request of network equipment receiving terminal in step 3, network equipment all changes all SCC in state of activation into deactivation status by state of activation, then passes through MAC layer signaling to terminal.
