Description
Technical field
The present invention relates to wireless communication technology field, relate in particular to a kind of changing method and device of serving cell of mobile terminal.
Background technology
The same with most of wireless protocols, IEEE 802.16 agreements are defined the switching of serving cell of mobile terminal, and purpose is the continuity that guarantees portable terminal business in moving process, improves the impression that the user experiences.
802.16e standard code a kind of essential switch mode, referred to as HO (handover), in fact be exactly usually said direct-cut operation.Two kinds of optional switch mode: MDHO (grand diversity switching) and FBSS (fast B S switching) also are provided in addition.What the regulation portable terminal must be supported among the WiMAX16e is direct-cut operation.
Portable terminal obtains the information of neighbor cell by the message of current serving BS broadcasting, perhaps distribute sweep spacing or sleep interval to come contiguous residential quarter is scanned and the mode of finding range obtains adjacent cell information by request, it is assessed, seek potential Target cell.Both switched and to be initiated also can be initiated by base station to determine by the portable terminal decision-making.
The bottom process that the WiMAX system is switched comprised measurement before switching and triggering, switching occur and process, switch after the processes such as data retransmission.Specific as follows:
Portable terminal receives the network topological information of base station broadcast, after obtaining the information of neighbor cell and current service cell, Request System is distributed one group of scanning time slot, after this request meets with a response, portable terminal can be according to the scanning gap of base station feedback and the scanning information radio conditions to neighbor cell, namely switch the size of index, measure and report such as received signal strength RSSI, carrier interference ratio C/I NR etc.
When portable terminal detects its current RSSI or CINR and has reached the handoff threshold of the current service cell that the base station requires, portable terminal just can initiate to switch requirement, Current Serving BTS can send a notification message to target BS, target BS is confirmed to finish with former serving BS after being ready to switch required resource and obtaining necessary information, then, Current Serving BTS sends message to portable terminal, and indicating mobile terminal switches and can occur.
Before target BS begins transfer of data, portable terminal can with the target BS down-going synchronous, obtain the transformation parameter of its up-downgoing.If target BS can obtain the information of portable terminal, then network reenters process and will shorten.After reentry was finished, system began to recover data and connects.In the process of switching, some mail to the data of portable terminal former serving BS meeting buffer memory, and at this moment, former serving BS may can greatly reduce data degradation like this with this part data retransmission to target BS, improves the service connection performance on upper strata.
This handoff procedure, might be two residential quarters that occur under the same base station, also might occur among different access business network ASN (Access Service Network) or the connectivity serving network CSN (Connectivity Service Network); After handoff procedure was triggered, the network elements such as ASN need to carry out the change process of corresponding data, signaling bear, guaranteed the continuous and consistency that data service connects.These all can make to switch in a period of time and finish, and this section period, and the other times that comprise in switching, are called as handover delay.
In the process of whole switching, because the existence of handover delay can cause whole system some unsettled situations to occur when switching, for example in the scene of Fig. 1 and Fig. 2:
In the situation that Fig. 1: portable terminal switches between base station A coverage cell and base station B coverage cell, enter Zone switched after, the switching index that detects base station B coverage cell at the I point has satisfied handoff threshold, initiate handoff procedure, through behind the handover delay, to finish in the switching of II point, portable terminal begins to provide service by base station B, the network that base station A and base station B are arranged in the handoff procedure does not all the time have the situation that goes offline and occurs.
And for the situation of Fig. 2, portable terminal equally enter Zone switched after, detecting initiation at the I point switches, because this moment, the speed of portable terminal was very fast, just can finish switching when arriving the IV point, and in the process that the III point is ordered to IV, only has the covering of base station B, handoff procedure is not also finished, and just might cause the network connection failure of terminal, namely goes offline.
Fig. 2 situation occurring generally is because the translational speed of fast mobile terminal is too fast, and under current social environment, traffic environment is become better and better, and at highway, under the high speed conditions such as magnetic suspension train, portable terminal then is easy to occur the situation that similarly goes offline.

The embodiment of the invention provides a kind of changing method of serving cell of mobile terminal, as shown in Figure 3, comprising:
Step S301, determine the quantity of the Serving cell that portable terminal has switched in a nearest setting-up time interval of distance current time.
Step S302, when the quantity of determining when setting amount threshold, reduce the handoff threshold of this portable terminal less than setting handoff threshold.
Step S303, when the switching index of the neighbor cell of the current service cell of this portable terminal that detects reaches the handoff threshold of this portable terminal, the Serving cell of this portable terminal is switched to this neighbor cell.
Below in conjunction with accompanying drawing, with preferred preferred embodiment method provided by the invention and device are described in detail.
The detail flowchart of the changing method of the serving cell of mobile terminal that Fig. 4 provides for the embodiment of the invention comprises:
The quantity of step S401, the Serving cell that switched for portable terminal in the statistics setting-up time section in this step, begins Serving cell of the every switching of portable terminal, the quantity of the Serving cell that record has switched at the initial time of each setting-up time section.
In step S402, this step, whenever switching to a new Serving cell, the handoff threshold of this portable terminal is set, specifically can adopts various method to set up of the prior art, for example:
Obtain the handoff threshold of current service cell, and this handoff threshold that will obtain is as the handoff threshold of this portable terminal.
Step S403, after current setting-up time section finishes, the quantity of the Serving cell that has switched of the record that obtains, this quantity are the quantity of the Serving cell that portable terminal switched in current setting-up time section.
Can with this setting-up time section as the setting-up time interval among the above-mentioned steps S301, then enter step S405 in the embodiment of the invention; Also can enter step S404, further determine the quantity of the Serving cell that portable terminal has switched in the setting-up time interval.
