Description
Technical field
The present invention relates to moving communicating field, and in particular to a kind of method of terminal different system cell gravity treatment, terminal and be
System.
Background technology
The development of PMC is greatly enriched the life of people so that people can in any place, it is any
Time, it is any under the conditions of can easily incoming communication network, enjoy the Communications service of voice or data.People are for two-forty
The craving of mobile communication and the variation of business promote the development and evolution of mobile communication technology, current 3G (Third Generation) Moblie
Technology is ripe and enters the commercialization epoch, Long Term Evolution (the Long Term Evolution, abbreviation of 3GPP
LTE the trial period) is also progressed into, the office that the second generation (2G), the third generation (3G) and LTE mobile communication network coexist is occurred in that

As a example by SCDMA/GSM dual-mode terminals, when the value of the different system cell gravity treatment thresholding of configuration is than parameter SintrasearchAnd Sintersearch's
Value all hours, there is terminal in the range of the TD network coverages preferentially to carry out gravity treatments of the TD with frequency or alien frequencies adjacent area, secondly just can
Consider gravity treatment to GSM cell.
The QoffsetS, nAnd QhystsValue be that the ps domain business for making terminal preferentially resides in non-GSM network
Value.Specifically, QoffsetS, nSpan be preferably even number between 0 to 40.QhystsSpan be preferably-
Integer between 50 to 50.By taking TD-SCDMA/GSM dual-mode terminals as an example, in the case where TD networks disclosure satisfy that service quality,
Qoffset can be adjustedS, nAnd QhystsValue with cause terminal try one's best in ps domain resides in TD networks, QoffsetS, nWith
QhystsSpecific value determine when being network planning network optimization, broadcasted by network side.
Cause that terminal ps domain business preferentially resides in the parameter value in non-GSM network by testing to obtain, for system
Different values it is different.
It is above-mentioned only ps domain business refer to：Terminal only has PS business and is resident；Or refer to：Terminal only supports PS business；Or
Person refers to：Terminal was not resident CS business in current area.Determination methods can be realized using prior art, no longer gone to live in the household of one's in-laws on getting married herein
State.
The step of above-mentioned terminal carries out different system cell gravity treatment from the special cell reselection parameters of the ps domain for receiving is wrapped
Include：The RSCP value Sx that the PCCPCH of terminal measurement current area is obtained, when the Sx is less than the different system cell gravity treatment door
Limit SSearch, RATWhen, start the measurement to different system cell, according to QoffsetS, nAnd QhystsThe calculating of R criterions is carried out, is carried out
Different system cell gravity treatment.
The above method is applied to the multi-mode multi-standby terminal of any system, such as LTE/GSM double-mode and double-standby terminals, now ps domain
Should try one's best and be resident in the lte networks；TD-SCDMA/GSM double-mode and double-standby terminals, during now ps domain should try one's best and reside in TD networks；
The mould double-standby terminals of LTE/TD-SCDMA/GSM tri-, now ps domain should try one's best and reside in LTE network etc..
By the present invention, when only ps domain business is resident, ps domain can preferentially be resident suitable net to multi-mode multi-standby terminal
