The embodiment of the invention has proposed a kind of method at the wireless access system re-selecting cell, the terminal that can guarantee idle condition by this method selects appropriate RAT sub-district to carry out resident, by rational resident gravity treatment, shortened the service access time, improved service access efficient, guaranteed the service communication quality, reduced the potential switching in the business procedure, further saved air interface resource, improved the capacity of system, satisfy user's demand better, further ensured the coordination of xenogenesis wireless network.
Referring to Fig. 2, a kind of method at the wireless access system re-selecting cell that the embodiment of the invention proposes specifically may further comprise the steps:
Step 101: the relevant information that adjacent R AT is collected in the current resident RAT sub-district of terminal.
The relevant information that adjacent R AT is collected in the current resident RAT sub-district of terminal specifically includes but not limited to following information:
The Qos service that adjacent R AT can provide, for example adjacent R AT can provide the Qos restriction of best service;
The loading condition of the loading condition of adjacent R AT: adjacent R AT can be based on the RAT statistical property, and its promptness can not guarantee fully; The loading condition of adjacent R AT also can be based on the timely occupation condition of tabulation sub-district among the RAT, and it has higher promptness;
The mobility tenability of adjacent R AT: different RAT is owing to its radio characteristics difference, so determined that the mobility tenability of RAT also is inconsistent, the mobility tenability of different districts also may there are differences (causing such as covering) among the identical RAT;
The service tariff state of adjacent R AT: different RAT might there are differences the rate of different business, and same RAT identical services also may there are differences (certain period certain professional sales promotion being given a discount as operator) in the different periods;
The professional ability of adjacent R AT: different RAT may there are differences the tenability of different business, and same RAT also may there are differences in the different periods.
Step 102: the relevant information code set of each adjacent R AT that the current resident RAT sub-district of terminal will be collected is synthesized RAT information parameter combined value.
The relevant information of the adjacent R AT that collect the current resident RAT sub-district of terminal is used for auxiliary gravity treatment RAT sub-district, need be broadcast to terminal by the air interface of current resident RAT sub-district.In order to save the air interface resource of the current resident RAT sub-district of terminal, encode and make up the related information parameters of adjacent R AT, simplify these information of compression, reduce the data traffic volume of the current resident RAT sub-district air interface of terminal.
Information parameter coding is that the relevant information with RAT is simplified to the least possible amount of information, in actual applications, can use different numerals to come the related information parameters of RAT is encoded, for example, can be divided into four grades according to table 1 pair RAT occupation condition at the loading condition of adjacent R AT.
| RAT resource occupation amount | The busy grade of resource |
| >85％ | 3 |
| 60％~85％ | 2 |
| 40％~60％ | 1 |
| <40％ | 0 |
Table 1
For example at the mobility tenability of adjacent R AT, suppose the current RAT1 of having, RAT2, RAT3 and four wireless access systems of RAT4, the mobility tenability of different RAT correspondences is as shown in table 2, wherein because the mobility tenability of RAT2 and RAT3 is identical, so both belong to a grade.
| RAT | Mobility is supported grade |
| RAT1 | 2 |
| RAT2 | 1 |
| RAT3 | 1 |
| RAT4 | 0 |
Table 2
The information parameter coding of the relevant information that adjacent R AT need be considered is combined into a value according to the least possible bit number, has just formed RAT information parameter combined value.The information content of RAT information parameter combined value comprises static information and/or multidate information, static information comprises the Qos information on services that adjacent R AT provides, the mobility tenability information of adjacent R AT, the service tariff state information of adjacent R AT, professional ability information of adjacent R AT etc., and multidate information comprises the loading condition information of adjacent R AT etc.The generation type of RAT information parameter combined value has following dual mode, but is not limited to this dual mode:
Mode 1: the situation of two kinds of relevant informations among the adjacent R AT is considered in supposition, if the situation of first kind of relevant information is divided into M grade, the situation of second kind of relevant information is divided into N grade, then can pass through CEILING (log
2M)+CEILING (log
2N) individual bit (CEILING is defined as and rounds up) is represented the combination of all situations.Such as supporting grade both of these case (referring to table 1 and table 2) at busy grade of the resource among the adjacent R AT and mobility, the busy grade of resource can be passed through CEILING (log
24)=2 a bit identifies, and mobility supports grade can pass through CEILING (log
23)=2 a bit identifies, and then can obtain coding rule as shown in table 3.
| The busy grade of resource | Mobility is supported grade | RAT information parameter combined value |
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 0 | 2 | 2 |
| 1 | 0 | 4 |
| 1 | 1 | 5 |
| 1 | 2 | 6 |
| 2 | 0 | 8 |
| 2 | 1 | 9 |
| 2 | 2 | 10 |
| 3 | 0 | 12 |
| 3 | 1 | 13 |
| 3 | 2 | 14 |
Table 3
The busy grade decimal number 2 of resource can identify with two bits 10 in the table 3, mobility supports grade decimal number 2 to identify with two bits 10, represent so the busy grade of resource be 2 and mobility support that grade is that 2 RAT information parameter combined value is 10+10=1010, promptly decimal number 10.
Mode 2: the situation of two kinds of relevant informations among the adjacent R AT is considered in supposition, if the situation of first kind of relevant information is divided into M grade, the situation of second kind of relevant information is divided into N grade, then can pass through CEILING (log
2(M*N)) individual bit is represented the combination of all situations.Such as supporting grade both of these case (referring to table 1 and table 2) at busy grade of the resource among the adjacent R AT and mobility, all situations can be passed through CEILING (log
2(3*4))=4 a bit identifies, and then can obtain coding rule as shown in table 4.
| The busy grade of resource | Mobility is supported grade | RAT information parameter combined value |
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 0 | 2 | 2 |
| 1 | 0 | 3 |
| 1 | 1 | 4 |
| 1 | 2 | 5 |
| 2 | 0 | 6 |
| 2 | 1 | 7 |
| 2 | 2 | 8 |
| 3 | 0 | 9 |
| 3 | 1 | 10 |
| 3 | 2 | 11 |
Table 4
Generally, compound mode 2 is lacked than the bit number that compound mode 1 needs, but under the situation of the relevant information grade flexibility and changeability of adjacent R AT, need be the mutual more information of rule of combination.For the relevant information of considering adjacent R AT more than can the analogizing of two kinds of situations, is a kind of situation for the relevant information of considering adjacent R AT equally, then can pass through CEILING (log
2M) individual bit is represented the combination of this situation, and wherein M is the number of degrees of this kind situation.
Step 103: the current resident RAT sub-district of terminal is broadcast to terminal with the RAT information parameter combined value of each adjacent R AT by air interface.

Step 104: the terminal of idle condition is decoded to the adjacent R AT information parameter combined value of receiving, and from the RAT that meets resident condition, select the sub-district to carry out gravity treatment and measure, and according to measurement result gravity treatment RAT persistent district.
The terminal of idle condition is when the gravity treatment of RAT sub-district is prepared, at first consider the ability of oneself, the adjacent R of decoding then AT information parameter combined value, take all factors into consideration the factor (being provided with etc.) of various aspects as the mobility support of RAT, the resource busy extent of RAT, the Qos support of RAT, the service tariff information of RAT, user's hobby, from the RAT that meets most resident condition, select the sub-district to carry out gravity treatment and measure, and according to measurement result gravity treatment RAT persistent district.Do not have the sub-district to satisfy reselection conditions if meet most among the RAT of resident condition, then terminal will be initiated gravity treatment measurement and gravity treatment in next meets the RAT of resident condition, reside in the network as far as possible.
Present embodiment becomes a RAT information parameter combined value with the multinomial property combination of wireless access system, and be broadcast to terminal by RAT sub-district air interface, terminal is in the process of carrying out the sub-district gravity treatment, resolve RAT information parameter combined value, select appropriate RAT sub-district to carry out gravity treatment measurement and gravity treatment in conjunction with network characteristic and user preferences.The terminal that can guarantee idle condition by this method selects appropriate RAT sub-district to carry out resident, by rational resident gravity treatment, shortened the service access time, improve service access efficient, guaranteed the service communication quality, reduced the potential switching in the business procedure, further saved air interface resource, improve the capacity of system, satisfied user's demand better, further ensured the coordination of xenogenesis wireless network.
