Description
Technical field
The present invention relates to field of communication technology, more particularly to a kind of side for realizing CDMA saving power for terminal and improving user experience
Method.
Background technology
According to CDG#143 agreements, terminal, which searches net strategy, has one to be called Better Service Reselection（More
Good service reselection, hereinafter referred to as BSR）Algorithm.The content of the algorithm is as follows：In general, mobile station is required basis
Preferred Roaming List (optimum roaming list) and the instruction of current geographic area are operated in it and can capture most
Select on excellent network.
It is possible that since signal is temporarily blocked（Such as by a building）Or since mobile station is not covered in cell
In the range of lid, mobile platform started is just（Or after start）Most preferably 1X networks can not be captured.Also, mobile station is it is also possible to same
One geographic area captures a 1X network not in optimal network list.
When mobile station runs into such situation, mobile station is needed periodically to carry out better services gravity treatment, enabled it to
Optimal network can with when return in most-preferred networks.
According to this BSR algorithm, terminal when idle states can periodic removal search optimal network, this cycle by
Terminal itself configures, and is usually 3 minutes.This results in terminal and can be gone every few minutes in the case where not being locked into optimal network
Optimal network, the not only power consumption of such way are searched for, but also user can not dial electricity during optimal network is searched for
Words or online, have impact on the use of user.Present patent application is exactly in order to solve this problem, to help saving power for terminal and improve
The usage experience of user.

Search network server：The module is the module being not present in former cdma network, is the module that this patent proposes first,
Purpose is exactly to search for optimal network and whether decision-making CDMA terminals will switch for undertaking the information reported according to CDMA terminals
To the task of optimal network.The optimal network list that network server is reported according to terminal is searched, first judges whether terminal resides in most
On excellent network, if it is not, then starting the optimal network in region of search in order, if the optimal network priority searched is high
In the network that terminal is currently resident, then CDMA sms centers are issued a command to, the parameter for wanting handover network is carried in instruction.If search
Rope to optimal network priority be not higher than the network be currently resident of terminal, then do not send instructions.Search network server and search for optimal net
The frequency of network can be set.Operator sets the frequency of search optimal network according to being actually needed.Such as search one in every 3 minutes
It is secondary.
CDMA sms centers：CDMA ends are sent to from the instruction for searching network server and in the form of short message for receiving
End；Network server module is searched for receiving the short message of the optimal network list of terminal reported from CDMA terminals and being given to.
In the present embodiment, realizing the system of CDMA saving power for terminal includes CDMA terminals, cdma network and searches network server；
Wherein, cdma network is the mobile network for supporting all CDMA protocol versions；Network server is searched, is used to help CDMA
Terminal searching optimal network；CDMA terminals are to support the mobile terminal of the various protocol versions of CDMA.
In the present embodiment, realizing the method for CDMA saving power for terminal includes system side and two processing procedures of end side：
CDMA end sides, as shown in Figure 1, including
101st, CDMA terminals sort out a list for searching net priority according to itself PRL and parameter configuration.Namely
Say first inside list be limit priority network, Article 2 is the network of the second priority, and so on.
102nd, CDMA terminals search net priority list to system side transmission in a particular format by short message and currently it is stayed
The parameter of the network stayed.Actually this parameter for searching net priority list and its current resident network, which has been ultimately delivered to, searches
Network server.
103rd, CDMA terminals perform handover to the action of optimal network according to the instruction of system side.If system side does not have
Send instructions and tell terminal to need if being switched to optimal network, terminal will not switch, to achieve the purpose that power saving.
System side, as shown in Fig. 2, including
201st, cdma network（Sms center）Receive from CDMA terminals search net priority list and current it is resident
Network parameter short message and the short message handed to search network server.
202nd, network server searching net priority list and its current resident network and help according to CDMA terminals is searched
CDMA terminal searchings one's respective area optimal network.
203rd, search network server search after optimal network by by CDMA sms centers in the form of short message it is whole to CDMA
End sends the instruction for being switched to optimal network.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement made within refreshing and principle etc., should all be included in the protection scope of the present invention.
