With reference to Fig. 4, it is as follows that the described cluster of the embodiment of the invention listens user terminal changing method network side to process detailed process:
Step 402 listens user's switching controls module to start working, and starts and listens user's switching cycle timer, and the cycle was defaulted as for 3 seconds;
Step 403 in the present embodiment, after 3 seconds, is listened user's switching cycle timer expiry;
Step 405 listens user's switching controls module to listening user's handover information generation module to send a notification message, and carries group identification in the message;
In the said process, for adjacent area physic channel information and these two message of called measuring control information, preferential physic channel information, the called measuring control information of rear transmission of sending in the embodiment of the invention.
With reference to Fig. 5, the described cluster of the embodiment of the invention listens the concrete processing procedure of the autonomous changing method end side of user terminal as follows:
Step 502 listens user's handover information receiver module monitor set faciation of listening of user terminal to close control channel, receives the adjacent area physic channel information that network side sends;
Step 503 listens user's handover information receiver module that the adjacent area physic channel information that receives is saved in this locality, for follow-up when independently switching;
Step 504 listens user's handover information receiver module monitor set faciation to close control channel, receives the called measuring control information that network side sends;
Step 505 after listening user's handover information receiver module to receive called measurement control message, is transmitted to a tin user mobility judging module with this message.Listen the user mobility judging module according to the target cell information in the called measurement control message, carry out switch decision, comprising:
Listen the user mobility judging module to require terminal physical layer periodically to report designated cell wireless signal measurement result.Behind the measurement report of listening the user mobility judging module to receive that physical layer reports, according to the threshold value that provides in the called measuring control information, judge whether current measurement result satisfies tin autonomous switching condition of user: listen the autonomous handover triggering condition of user terminal if measurement result does not satisfy, listen so the user mobility judging module to continue to wait for the new measurement report of physical layer, proceed to judge; Listen the autonomous handover triggering condition of user terminal if measurement result satisfies, then change step 506 over to;
Step 507 listens user terminal to enable the physic channel information of the local Target cell of having preserved, and autonomous the switching is linked in the Target cell, continues to keep listening User Status, and repeating step 502 is to step 507.
Network side is when sending adjacent area physic channel information and called measuring control information, can at first send the adjacent area physic channel information, then send called measuring control information, can guarantee to the full extent like this when listening the user mobility judging module when judging that measurement report satisfies switching condition, the physic channel information of Target cell has been preserved in terminal this locality, listens the user to be linked into the time of new residential quarter thereby shorten.To the access user that lags, access the switching duration of listening the user if need to shorten to lag, can improve by the switching cycle timer duration of adjusting network side.Such as, the switching cycle timer duration of net side can be changed littlely,, be revised as 2 seconds the frequency that sends to increase adjacent area physic channel information and called measuring control information such as 3 seconds from present embodiment.
In addition, because network side for adjacent area physic channel information and called measuring control information, is to adopt the mode that periodically repeats to send.In this case, listen user terminal to receive this two information at every turn, all need whole decodings, and with the parameter that parses, replace existing data in the local data district, also need the mobility judging module to upgrade decision algorithm.Generally, the content in adjacent area physic channel information and the called measuring control information can often not change.Therefore, listen user terminal to switching the processing complexity of message in order to reduce, in adjacent area physic channel information and the called measuring control information, all designed a message identification (ValueTag) cell, in order to represent whether adjacent area physic channel information or called measuring control information content that network side generates variation has occured: if do not change, then the ValueTag value is constant, listens user terminal can ignore the information that this is received; If variation has occured, so the ValueTag value the last time change, listen a user terminal according to this information content of receiving, to upgrade accordingly processing.The database change processing module of network side design, its effect are exactly that notice is listened user's handover information generation module, adjusts the ValueTag value after the called handoff functionality relevant parameter configuration in Operation and Maintenance personnel Update Table storehouse.Certainly, ValueTag also can directly be set to 0 or 1,0 this information of expression and not become, and 1 this information of sign changes, and ValueTag also can be set to other values, and whether as long as can change by indication information, the present invention is not construed as limiting this.
In another embodiment of the present invention, also can send not according to the mode in above-described embodiment called measuring control information, listen user terminal also can carry out switch decision according to handover decision mechanism of the prior art, when determining to switch to Target cell, judge the local physic channel information of whether preserving Target cell, if have, then enable the physic channel information of Target cell after, switch to Target cell; If no, then wait for to receive the adjacent area physic channel information after, enable again the physic channel information of Target cell after, switch to Target cell.
Can be found out that by such scheme network side will listen the user to switch voluntarily information needed, by the cluster associated control channel, periodically send to and listen user terminal.The user that listens who listens user terminal to receive network side is switched information needed, and according to switching information needed, finishes voluntarily Target cell and measure, and measurement result judges, and enables Target cell physical channel configuration parameter, and the process that is linked into Target cell is processed.Listen user terminal in handoff procedure, with network side without signalling interactive process.Therefore, the present invention can be so that cluster listens the user in the process of conversion access residential quarter, enable fast the group service parameter channel configuration of Target cell, prevent that interrupting from appearring in speech business, thereby realized that namely cluster listens user's mobility functions, guaranteed again fast and efficiently business characteristic of cluster.
Compared with prior art, listen the user in former Serving cell, by monitoring the cluster correlated channels of former Serving cell, obtained the cluster physical resource information of Target cell.Therefore after listening user terminal independently to switch to Target cell, do not need the process that again reads new Serving cell system information and read the TCCCH channel information, the user is resident directly can to monitor the group service channel in the new residential quarter behind new residential quarter but listen, and receives the group service data.Enable the process of new cell parameter configuration, because without aerial reciprocal process, its processing is very fast, consuming time is 10 milliseconds of ranks, therefore, can not allow the user produce the impression of any voice latency.So the method has shortened substantially cluster and has listened the service disconnection duration of user in handoff procedure.
One of ordinary skill in the art will appreciate that all or part of step in the said method can come the instruction related hardware to finish by program, described program can be stored in the computer-readable recording medium, such as read-only memory, disk or CD etc.Alternatively, all or part of step of above-described embodiment also can realize with one or more integrated circuits.Correspondingly, each the module/unit in above-described embodiment can adopt the form of hardware to realize, also can adopt the form of software function module to realize.The present invention is not restricted to the combination of the hardware and software of any particular form.
