Embodiment
In daily life, people tend to go to familiar place along fixing circuit usually, though also can change circuit sometimes, this is a few cases after all, and for example: the working clan in city travels to and fro between between family and the company along fixing circuit every day; People also have fixing destination and middle circuit usually if will go to lie fallow or do shopping.If the terminal that the network handoff angle from the communications field, above-mentioned situation just are equivalent in the network need be carried out the sub-district switching because of being moved, and all can switch in most cases to certain or some fixing sub-districts.Therefore, the present invention moves according to terminal has the governed characteristics of certain rule when switching, a kind of strategy that wireless terminal switches of optimizing is proposed: the historical record that utilizes the switching of terminal storage under high-speed moving state, allow terminal maximum sub-district of first search switching times from neighbor cell list, increase terminal so greatly and searched for the probability that just finds suitable Target cell for the first time, shortened the time that switch the sub-district.
Basic thought of the present invention is: terminal storage is carried out the historical record that switch the sub-district; After terminal is received the neighbor cell list that the base station issues, rearrange neighbor cell list according to the historical record of having stored that carries out switching the sub-district; Whether the sub-district of searching for successively and measuring in the tabulation according to the neighbor cell list of resetting meets switching condition, and reporting base station when determining that the sub-district meets switching condition switches to the sub-district that meets switching condition under the control of base station.
Wherein, when determining in the process of described search and measurement that the sub-district does not meet switching condition, continue the next sub-district of search, and measure it and whether meet switching condition.
Further, switch to the sub-district of upgrading former storage behind the sub-district that meets switching condition and switch related content in the historical record.
Wherein, the historical record that described terminal carries out switching the sub-district can comprise: the information of cell-of-origin information when terminal is switched and all the target switching cells corresponding with the cell-of-origin also comprises the number of times that switches to all target switching cells from the cell-of-origin.
Below in conjunction with drawings and the specific embodiments the present invention is described in further detail.
Fig. 1 realizes the method realization flow schematic diagram that switch the sub-district down for high speed moving state of terminal of the present invention, and as shown in Figure 1, this flow process performing step is as follows:
Step 101: terminal storage is carried out the historical record that switch the sub-district;
Be specially: terminal keeps one section space in non-volatile internal or external memory, be used for storage terminal and carry out the historical record that switch the sub-district, the described historical record that carries out switching the sub-district can comprise: the information of cell-of-origin information when terminal is switched and all the target switching cells corresponding with the cell-of-origin also comprises the number of times that switches to all target switching cells from the cell-of-origin.For example: terminal was once switched to sub-district B, sub-district C and sub-district D respectively from sub-district A, and corresponding switching times is respectively: 45 times, 50 times and 32 times, so, the cell-of-origin information when described terminal is switched is sub-district A; The information of described all target switching cells corresponding with the cell-of-origin is: sub-district B, sub-district C and sub-district D, corresponding respectively corresponding switching times: 45 times, 50 times and 32 times.
Step 102: after receiving the neighbor cell list that the base station issues, rearrange neighbor cell list according to the historical record of having stored that carries out switching the sub-district;
Be specially: terminal is received current for after it provides the neighbor cell list that serving base station issues, rearrange neighbor cell list according to the historical record of having stored that carries out switching the sub-district, aligning method can be: contrast has been stored carries out the historical record that switch the sub-district, and the sub-district that once switching times was maximum in the neighbor cell list that the base station is issued comes first of neighbor cell list of rearrangement; In the neighbor cell list that the base station is issued once switching times time many sub-districts come second of neighbor cell list of rearrangement; By that analogy.
Step 103: whether the sub-district of searching for successively and measuring in the tabulation according to the neighbor cell list of resetting meets switching condition, reporting base station when determining that the sub-district meets switching condition, and execution in step 104 then; Continue the next sub-district of search when determining that the sub-district does not meet switching condition, and measure it and whether meet switching condition;
Be specially: terminal begins sub-district the search listing successively according to the neighbor cell list of resetting from the sub-district that makes number one, and whether the sub-district that measurement searches meets switching condition, as: whether the signal strength signal intensity of sub-district reaches threshold condition, if the sub-district meets switching condition, then with qualified reporting district information base station, and other sub-district that stops search; If the sub-district does not meet switching condition, then continue the next sub-district in the neighbor cell list that search resets, and measure it and whether meet switching condition.
Step 104: under the control of base station, switch to the sub-district that meets switching condition;
Be specially: terminal is switched to Target cell under the control of base station after finding the sub-district and reporting base station that meets switching condition.
After the above-mentioned steps 104, the present invention further comprises: the related content in the historical record is switched in the sub-district that terminal is upgraded former storage, for example: if this time switching to from sub-district A of terminal switches to sub-district B, and the number of times that switches to sub-district B from sub-district A in the former record is 45 times, and the number of times that will switch to sub-district B from sub-district A during then terminal will write down is updated to 46 times.
Among the present invention, cell-of-origin information in the described historical record that carries out switching the sub-district when comprising that terminal is switched, the information of all the target switching cells corresponding and terminal with the cell-of-origin from the cell-of-origin outside the number of times that all target switching cells switch, also can comprise: terminal is in the resident time of target switching cell, terminal from the cell-of-origin to the additional reference conditions such as signal quality of the probability and the target switching cell of target switching cell handoff failure, in actual application, with historical switching times is the main reference condition, determines the sequencing of search and measurement neighbor cell in conjunction with above-mentioned additional reference conditions.
Here, described with terminal resident time of target switching cell as a supplement reference conditions former because: actual network coverage situation may make the signal of target switching cell between cell-of-origin and Target cell in the very little coverage better, but because terminal is in high-speed moving state, terminal will find that signal dies down rapidly after switching to these Target cells at once, have to initiate once more switch, therefore, carry out to avoid as far as possible when switch the sub-district switching in terminal to these interim sub-districts, more to avoid when especially terminal is in high-speed moving state, so, in the middle of actual application, these interim sub-districts can be come with the switching times is last according to the neighbor cell list of resetting.
Described with terminal from the cell-of-origin to the probability of target switching cell handoff failure as a supplement reference conditions former because: terminal is handoff procedure, may be owing to the more resource that causes of terminal use's number of Target cell is distributed inadequately, or the service quality of to be switched terminal (QoS) priority is high and can not carry out the sub-district and switch, therefore, the probability of target switching cell handoff failure suitably can be postponed by actual needs the bigger order of sub-district in the neighbor cell list that with the switching times is the foundation rearrangement.
Described signal quality with the target switching cell as a supplement reference conditions former because: switch requirement though signal strength signal intensity and signal to noise ratio etc. are all once satisfied in the sub-district in the historical record, but be not to show that the signal quality of these sub-districts is all identical, so can the order of better quality of signal sub-district in the neighbor cell list that with the switching times be the foundation rearrangement is suitable to prerequisite, and suitably postpone for the relatively poor order of sub-district in the neighbor cell list that with the switching times is the foundation rearrangement of signal quality.
Like this, be the main reference condition with historical switching times, and in conjunction with the definite sequencing of searching for and measuring neighbor cell of above-mentioned additional reference conditions, so that further improve the solution of the present invention.
