Embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is further set forth.
In limited network, because the user terminal negligible amounts that can insert, and probably in the most of the time, not having user terminal to insert, network of the prior art is in running order for a long time, can cause the serious wasting of resources; Simultaneously because the enormous amount of limited network; Can't guarantee all to adopt different frequencies between the adjacent limited network on the Frequency Distribution; If all limited networks are all in running order for a long time, promptly like BCH (Broadcast Channel, broadcast channel) and PCH (Paging Channel; PCH) etc. common signal channel is in continuous emission state for a long time, then between limited network, can cause bigger same frequency to disturb.In addition, if limited network and public network are together frequently, then a large amount of limited networks will cause very big same frequency to disturb to public network.
Therefore in practical application, network does not need in running order for a long time, in the most of the time, can be in idle condition.Embodiments of the invention are divided into off-mode, operating state and idle condition with the state of limited network.So-called off-mode is meant that the limited network power supply is disconnected.So-called operating state is meant the common signal channel normal transmission in the limited network.So-called idle condition is meant that common signal channel in the limited network is in not launch or the very long state of transmission interval.
As shown in Figure 1, Fig. 1 is the sketch map of embodiment of the invention limited network state conversion.Be in the limited network of off-mode, when power supply was closed, limited network converted idle condition or operating state into from off-mode.If need to work immediately after the limited network start, when then power supply was closed, limited network converted operating state into from off-mode; Otherwise when power supply was closed, limited network converted idle condition into from off-mode.And under the situation of limited network power supply closure, this limited network can be changed according to actual conditions in working order and between the idle condition.When there being the user terminal that allow to insert resident or when inserting, this limited network is transformed into operating state in the limited network; Resident or when inserting, this limited network is transformed into idle condition when the user terminal that allow to insert in the limited network, also be that common signal channel in the limited network is in and does not launch or the very long state of transmission interval.
As shown in Figure 2, Fig. 2 is the flow chart of a kind of limited network state maintaining method of the embodiment of the invention, may further comprise the steps:
When the access state information of user terminal changed, limited network obtained the access state information of this user terminal.This access state information comprises that user terminal leaves limited network near limited network and user terminal.
Limited network can obtain this access state information from user terminal; Also can obtain this access state information from the network side of limited network place or adjacent macro cell; Limited network also can transmit through the up of monitoring users terminal, perhaps self obtains this access state information through acoustic control, bluetooth or alternate manner.
Limited network gets access to after the access state information described in the step 201, triggers limited network in working order, change between idle condition and the off-mode according to this access state information.Therefore the embodiment of the invention is obtained access state information with limited network from user terminal and is regarded as user terminal and triggers limited network and carry out state exchange; Limited network is obtained access state information from the network side of its place or adjacent macro cell to be regarded as network side and to trigger limited network and carry out state exchange; If limited network and macrocell signal are with covering; Then limited network obtains access state information from the network side of its place macrocell; If the different coverings with the macrocell signal of limited network, then limited network obtains access state information from the network side with the adjacent macro cell of its close together; Limited network self is obtained access state information be regarded as limited network triggering carrying out state exchange.Thereby can the embodiment of the invention be triggered the mode that limited network carries out state exchange is divided into: user terminal triggers, network side triggers and limited network triggers.
Embodiments of the invention trigger limited network at user terminal when leaving limited network near limited network respectively and carry out state exchange.The mode that the triggering limited network carries out state exchange comprises: user terminal triggers, network side triggers and limited network triggers.
Triggering limited network with user terminal, to carry out state exchange be example, when the user terminal that is in connection status during near limited network, and in conjunction with Fig. 3, Fig. 4, and as shown in Figure 6, may further comprise the steps:
Step 601, user terminal are measured the signal quality of limited network 1 during near limited network 1.
When user terminal during, trigger the signal quality of limited network 1 is measured near limited network 1.Wherein, trigger user terminal to limited network 1 carry out signal quality measured method comprise multiple, for example: trigger and based on user terminal place or adjacent macro cell triggering etc. based on the user terminal current location.So-called based on the triggering of user terminal current location, be meant that user terminal begins the transmission signal quality of limited network 1 is measured when user terminal current location distance limited network 1 reaches in the predetermined value.So-called trigger, be meant when user terminal to get into that limited network 1 belongs to or during adjacent macrocell 1, user terminal begins the signal quality of limited network 1 is measured based on user terminal place macrocell.As shown in Figure 3, limited network 1 covers together with macrocell 1 signal, when then user terminal gets into the macrocell 1 at limited network 1 place, begins the signal quality of limited network 1 is measured; As shown in Figure 4, the different coverings with macrocell 1 signal of limited network 1 when then user terminal gets into the adjacent macrocell 1 of limited network 1, begin the signal quality of limited network 1 is measured.
And limited network 1 is carried out when signal quality measured beginning, user terminal starts timer.If user terminal can measure transmitting of limited network 1 before timer expiry, show that then limited network 1 is in running order, user terminal can directly whether decision switches to limited network 1 according to measurement result.If user terminal still can't measure transmitting of limited network 1 behind timer expiry, then forward step 602 to.
The information that step 602, user terminal can't measure limited network 1 sends to limited network 1.
Owing to establishing RRC (Radio Resource Control between user terminal that is in connection status and the limited network 1 place macrocell 1; Radio Resource control) connect; Therefore user terminal can directly pass through the RRC signaling of the RRC connection of foundation, and user terminal is sent to user terminal place or adjacent macrocell 1 near the information that limited network 1 still can't measure limited network 1.If exist X2 interface to connect between macrocell base station, 1 place and the limited network 1, then through X2 interface the information that above-mentioned user terminal can't measure limited network 1 be forwarded to limited network 1 by base station, macrocell 1 place; If do not exist X2 interface to connect between macrocell base station, 1 place and the limited network 1, then the information that above-mentioned user terminal can't measure limited network 1 is forwarded to core net by base station, macrocell 1 place, be forwarded to limited network 1 by core net again.
Step 603, limited network 1 is judged current state, if operating state then keeps the work at present state constant; If idle condition then is transformed into operating state.
Step 604, limited network 1 returns to user terminal with in running order response.
Limited network 1 sends to macrocell 1 with in running order response; If exist X2 interface to connect between macrocell base station, 1 place and the limited network 1; Then limited network 1 sends to base station, macrocell 1 place through X2 interface with above-mentioned limited network 1 in running order response, by base station, macrocell 1 place this response is turned back to user terminal again; If do not exist X2 interface to connect between macrocell base station, 1 place and the limited network 1; Then limited network 1 sends to base station, macrocell 1 place through core net with above-mentioned limited network 1 in running order response, by base station, macrocell 1 place this response is turned back to user terminal again.
In practical application, the dispensable step of step 604 also is that limited network 1 can return in running order response to user terminal, also can not return in running order response to user terminal.
When the user terminal that is in idle condition during near limited network, in conjunction with Fig. 3, Fig. 4, and as shown in Figure 7, may further comprise the steps:
Step 701, user terminal are measured the signal quality of limited network 1 during near limited network 1.
When user terminal during, trigger the signal quality of limited network 1 is measured near limited network 1.Wherein, trigger user terminal to limited network 1 carry out signal quality measured method comprise multiple, for example: trigger and based on user terminal place or adjacent macro cell triggering etc. based on the user terminal current location.
And limited network 1 is carried out when signal quality measured beginning, user terminal starts timer.If user terminal can measure transmitting of limited network 1 before timer expiry, then user terminal directly determines according to measurement result whether gravity treatment is to limited network 1.If user terminal still can't measure transmitting of limited network 1 behind timer expiry, then forward step 702 to.
Step 702, user terminal are set up RRC to the base station of place or adjacent macro cell 1 and are connected.
If user terminal still can't measure the signal quality of limited network 1 behind timer expiry; Then initiate RRC to the base station of this user terminal place or adjacent macro cell 1 and connect the request of setting up, the RRC that sets up between the base station of user terminal and macrocell 1 connects.
The information that step 703, user terminal can't measure limited network 1 sends to limited network 1.
After RRC connects foundation; User terminal sends to user terminal place or adjacent macrocell 1 with user terminal near the information that limited network 1 still can't measure limited network 1 through the RRC signaling, and the base station by macrocell 1 place is forwarded to limited network 1 through X2 interface with aforementioned information then; Perhaps user terminal is through the RRC signaling; User terminal is sent to user terminal place or adjacent macrocell 1 near the information that limited network 1 still can't measure limited network 1, and the base station by macrocell 1 place is forwarded to limited network 1 through core net with aforementioned information then.
Step 704, limited network 1 is judged current state, if operating state then keeps current state constant; If idle condition then is transformed into operating state.
Step 705, limited network 1 returns to user terminal with in running order response.
Limited network 1 sends to base station, macrocell 1 place through X2 interface with in running order response, by base station, macrocell 1 place this response is turned back to user terminal again; Perhaps, limited network 1 sends to base station, macrocell 1 place through core net with in running order response, by base station, macrocell 1 place this response is turned back to user terminal again.
In practical application, the dispensable step of step 705 also is that limited network 1 can return in running order response to user terminal, also can not return in running order response to user terminal.
In the above-described embodiments, user terminal receives and discharges RRC automatically after the response message that limited network 1 returns and connect.Consider to occur the situation that user terminal does not receive the response message that limited network 1 returns in the practical application, if user terminal waits for that always limited network 1 returns response message, then can take RRC in a long time and connect, the waste resource.Therefore, user terminal starts timer in the information that can't measure limited network 1 when limited network 1 sends, if user terminal receives the response message of limited network 1 before the timer expiry, then discharges RRC automatically and connects; If user terminal does not receive the response message of limited network 1 yet behind the timer expiry; The process of user terminal repeating step 703 then; Continuation is sent the information that can't measure to limited network 1, sends when the information of user terminal to discharge the RRC connection when number of times surpasses predetermined value.
When user terminal leaves limited network, in conjunction with Fig. 5, and as shown in Figure 8, may further comprise the steps:
Step 801, user terminal are left limited network 1.
When the user terminal that is in connection status leaves limited network 1, owing to exist RRC to connect between the base station of the user terminal of this connection status and limited network 1 place macrocell 1, so limited network 1 can directly be known leaving of this user terminal.
When the user terminal that is in idle condition leaves limited network 1; Owing to do not exist RRC to connect between the base station of the user terminal of this idle condition and limited network 1 place macrocell 1; Therefore limited network 1 can't directly be known leaving of this user terminal, needs this user terminal to send the information that user terminal leaves to limited network 1.User terminal is before other macrocells are arrived in gravity treatment, and the base station initiation RRC connection foundation that belongs to macrocell 1 to limited network 1 is asked, and has set up after the RRC connection, and the information that user terminal leaves user terminal through the RRC signaling sends to limited network 1.
User terminal also can send the information that user terminal leaves to limited network 1 in gravity treatment after other macrocells.For example: the user terminal gravity treatment is arrived after the macrocell 2; In macrocell 2, initiate RRC and connect the request of foundation to the base station at macrocell 2 places; After having set up the RRC connection; User terminal sends the information that user terminal leaves through the RRC signaling to this base station, through X2 interface or core net this information is sent to limited network 1 by the base station again.
Limited network 1 returns response message to user terminal after receiving the information that user terminal leaves, and user terminal receives and discharges RRC after the response message and connect.Consider to occur the situation that user terminal does not receive the response message that limited network 1 returns in the practical application, if user terminal waits for that always limited network 1 returns response message, then can take RRC in a long time and connect, the waste resource.Therefore, user terminal starts timer in the information that will leave limited network 1 when limited network 1 sends, if user terminal receives the response message of limited network 1 before the timer expiry, then discharges RRC automatically and connects; If user terminal does not receive the response message of limited network 1 yet behind the timer expiry, then user terminal continues to send the information of leaving limited network 1 to limited network 1, when the information of user terminal is sent number of times above predetermined value, discharges RRC and connects.
Step 802, limited network 1 carries out the conversion of state according to the user terminal access situation of inside.
Limited network 1 receives the leave message of user terminal, and after user terminal returned response message, limited network 1 was in running order.At this moment, limited network 1 can have or not the user terminal of connection status to keep professional through its inside of RRC connection judgment, if having, then limited network 1 keeps operating state constant.Do not have the user terminal of connection status to keep professional if judge limited network 1 inside, then limited network 1 further judges that through the mode of paging its inside has or not the user terminal of idle condition resident, if having then limited network 1 keeps operating state constant; If not then limited network 1 is transformed into idle condition immediately; Perhaps limited network 1 starts a timer; Behind timer expiry, be transformed into idle condition; The user terminal of connection status inserts or the user terminal of idle condition is resident if in the setting-up time of timer, occur, and then limited network 1 keeps operating state constant, does not carry out state exchange.
Wherein, limited network 1 judges that through the mode of paging its inside has or not the user terminal of idle condition resident, comprises following two kinds of situation:
If be that limited network 1 is divided a TA (Tracking Area follows the tracks of the territory) separately during the network planning, then limited network 1 paging in TA allows the user terminal that inserts, also has user terminal resident if the paging of user's terminal response is arranged then think in the limited network 1; There is not user terminal resident if having the paging of user's terminal response then think in the limited network 1; Perhaps under the situation that does not have the paging of user's terminal response; Limited network 1 starts timer; Limited network 1 carries out paging once more behind timer expiry, if the paging number of times reaches predetermined value limited network 1 and also do not receive page response, then thinking does not have user terminal resident in this limited network 1.
If be not that limited network 1 is divided a TA separately during the network planning; Then limited network 1 sends paging request to core net; Allow the user terminal that inserts by core net paging in the TA scope at limited network 1 place, also have user terminal resident in the limited network 1 if the paging of user's terminal response is arranged then think; There is not user terminal resident if having the paging of user's terminal response then think in the limited network 1; Perhaps under the situation that does not have the paging of user's terminal response; Limited network 1 starts timer; Limited network 1 carries out paging once more behind timer expiry, if the paging number of times reaches predetermined value limited network 1 and also do not receive page response, then thinking does not have user terminal resident in this limited network 1.
More than be that user terminal of the present invention triggers the embodiment that limited network carries out state exchange, triggering limited network with network side more below, to carry out state exchange be that example is done embodiments of the invention and further described.Triggering mode that limited network carries out state exchange with network side, to be used for the situation that the connection status user terminal inserts and leave be that example is described.When the user terminal that is in connection status during near limited network, in conjunction with Fig. 3, Fig. 4, and as shown in Figure 9, may further comprise the steps:
Step 901, user terminal be during near limited network 1, the limited network tabulation that reports this user terminal to insert to network side.
When the user terminal of connection status switched to macrocell 1, the network side of macrocell 1 can be known the access of this user terminal, and macrocell 1 sends to user terminal through the base station, place and switches the message instruction.After user terminal receives this switching message instruction; To the limited network tabulation that macrocell 1 reports this user terminal to insert, the network side of macrocell 1 judges in this macrocell 1 or in the contiguous limited network whether have the limited network that allows this user terminal to insert according to this tabulation.If do not exist, then network side need not be notified limited network.As shown in Figure 3, the limited network 1 that the network side of macrocell 1 finds in the tabulation is present in this macrocell 1, then forwards step 902 to; As shown in Figure 4, the limited network 1 that the network side of macrocell 1 finds in the tabulation is the limited network of this macrocell 1 vicinity, then forwards step 902 to.
Step 902, the network side of macrocell 1 through X2 interface or core net to limited network 1 send have user terminal near information.
Step 903, limited network 1 receive after this information, carry out the conversion of state.If this moment, limited network 1 was in running order then keep operating state constant, if limited network was in idle condition then was transformed into operating state this moment.
Step 904, limited network 1 returns in running order response message to user terminal.Limited network 1 sends the in running order response message of limited network 1 to place or the base station of adjacent macro cell 1, by this base station this response message is forwarded to user terminal again.
In practical application, the dispensable step of step 904 also is that limited network 1 can return in running order response to user terminal, also can not return in running order response to user terminal.
When user terminal leaves limited network, in conjunction with Fig. 5, and shown in figure 10, may further comprise the steps:
Step 1001, when user terminal left limited network 1, the network side of limited network 1 place macrocell 1 can be known leaving of this user terminal.For example: when the macrocell 1 that user terminal belongs to from limited network 1 switched to macrocell 2, the network side of macrocell 1 can be known leaving of this user terminal.
Step 1002, the network side of macrocell 1 sends to limited network 1 with the information that user terminal leaves limited network 1.
After step 1003, limited network 1 received the information that user terminal leaves, limited network 1 was in running order; At this moment; Limited network 1 can have or not the user terminal of connection status to keep professional through its inside of RRC connection judgment, if having, then limited network 1 keeps operating state constant.Do not have the user terminal of connection status to keep professional if judge limited network 1 inside, then limited network 1 further judges that through the mode of paging its inside has or not the user terminal of idle condition resident, if having then limited network 1 keeps operating state constant; If not then limited network 1 is transformed into idle condition immediately; Perhaps limited network 1 starts a timer; Behind timer expiry, be transformed into idle condition; The user terminal of connection status inserts or the user terminal of idle condition is resident if in the setting-up time of timer, occur, and then limited network 1 keeps operating state constant, does not carry out state exchange.
The present invention comprises that also limited network self triggers the embodiment of state exchange.So-called limited network self triggers state exchange, is meant by limited network self to control the change of its state as the case may be.For example:, button perhaps is set, on limited network through carrying out state exchange or the like by the key control limited network because abnormal conditions cause the limited network outage and are in off-mode.
Core net can be known the change of limited network state, and when limited network carried out state exchange, core net informed that through the mode of paging this limited network allows all user terminals that insert.The state information that all user terminals that the mode of core net through paging allows to insert to this limited network send these limited networks is if success calling is then returned response to limited network.The state information of this limited network of user terminal storage then when user terminal during near this limited network, can directly be operated according to the state information of storing, and comprising:
If in the state information of user terminal storage, this limited network is in running order, then user terminal carries out signal quality measuredly to limited network, and need not notify limited network.
If in the state information of user terminal storage; This limited network is in idle condition; User terminal need notify limited network to be transformed into operating state, the base station of user terminal through the place macrocell to limited network send user terminal that this limited network allows to insert near information.Limited network receive this user terminal near information after, be transformed into operating state, and return response to user terminal through the base station of this macrocell.
In addition; In an embodiment of the present invention; Limited network also can transmit through the up of monitoring users terminal; Perhaps user terminal is monitored through audiomonitors such as acoustic control, bluetooths, when listen to the user terminal that limited network allow to insert insert, near or when leaving this limited network, trigger limited network and carry out the conversion of state.
The embodiment of the invention also provides a kind of limited network state maintenance system, comprising: state information transmitting apparatus and limited network.Wherein, the state information transmitting apparatus is used for the access state information to limited network transmission user terminal.Limited network is used for confirming dbjective state according to the access state information that receives, and carries out the corresponding state adjustment.Among the embodiment corresponding to the invention described above method; The access state information of user terminal can be sent by user terminal, also can send by network equipment, so in the limited network state maintenance system of the embodiment of the invention; The state information transmitting apparatus can be user terminal, also can be network equipment.
With the state information transmitting apparatus is that the situation of user terminal is example, and shown in figure 11, the limited network state maintenance system of the embodiment of the invention one comprises: user terminal 100 and limited network 200.
