A kind of method of paging is provided in one embodiment of the present of invention by way of example.As shown in Figure 2, the method comprises following part.
150, the identification information of receiving terminal place group.
It in 150, can be the identification information of base station sub-system receiving terminal place group.
The identification information of terminal place group can be sent by MSC, also can be sent by SGSN.For example, when in the service area of the terminal in paged group at MSC, MSC is to the identification information of base station sub-system transmitting terminal place group.
The identification information of the group of terminal can carry by paging (Paging) message.Certainly, the identification information of terminal place group also can carry by other message, for example, can carry out by new message the identification information of carried terminal place group
160,, according to the identification information of group, determine the paging subchannel of the corresponding Common Control Channel of identification information of this group.
In the present embodiment, can be by multiple terminals be divided into different groups, each group identifies by the identification information of corresponding group.And each group identification information is corresponding to a paging subchannel in Common Control Channel.In another embodiment of the present invention, base station sub-system can be preserved or by other means, for example, from HLR (Home Location Register, attaching position register) or MSC (Mobile Switching Centre, mobile switching centre) receive and obtain, obtain the corresponding relation between the identification information of group and the paging subchannel of its corresponding Common Control Channel, thereby base station sub-system can be determined the paging subchannel that the identification information of group is corresponding.
170, on this paging subchannel, send the first paging request message, this first paging request message comprises the identification information of this group.
In order to send the group of paging to this terminal place, can on the paging subchannel at this group place, send the first paging request message, by carrying the identification information of group in the first paging request message, the terminal that monitors this paging subchannel can receive the first paging request message, thereby can learn that this first paging request message is the paging to group.
In the present embodiment, can be according to the identification information of the group receiving, on the corresponding paging subchannel of identification information of this group, send the first paging request message, thereby the terminal to this group is carried out paging, thereby avoid network to carry out respectively paging or carry out paging on all paging subchannels all terminals in this group, improve paging efficiency, reduced resource consumption.
A kind of method of paging is provided in one embodiment of the present of invention by way of example.As shown in Figure 3, the method comprises following part.
210, the identification information of receiving terminal place group.
For example, can be that base station sub-system receives the first message.
This first message can be that MSC sends, and also can be sent by SGSN.For example, when in the service area of the terminal in paged group at MSC, MSC is to the identification information of base station sub-system transmitting terminal place group.The identification information of terminal place group can be by paging (Paging) message.Beep-page message carries the identification information of the group of this terminal.
220,, according to the identification information of group, determine the packet number of the corresponding Common Control Channel of identification information of group.
The packet number of determining the corresponding Common Control Channel of identification information of group can have various ways.For example, base station sub-system can obtain the number of physical channels of Common Control Channel.Base station sub-system can also further obtain the delivery value and the paging block number that set in advance, and this delivery value can be maximum endpoint groups number, and this delivery value also can be for being positioned at the some values between maximum endpoint groups number and null value.
For example, according to physical channel number and the paging block number of the identification information of terminal place group in the first message, the delivery value setting in advance, Common Control Channel, can determine the packet number N of the corresponding Common Control Channel of identification information of terminal place group in the first message
tS.
For example, can adopt following formula to determine the packet number of Common Control Channel:
N
TS＝((GroupID?mod?PresetModValue)mod(BS_CC_CHANSxN))div?N
Wherein, GroupID represents the corresponding group identification of the identification information of group, modular arithmetic is carried out in mod representative, PresetModValue is the delivery value setting in advance, for example PresetModValue can be set in advance as 1000, BS_CC_CHANS and represent the number of the physical channel of general controls channel, the number that N is paging block, x represents multiplying, and division of integer computing is carried out in div representative.
For example, according to the identification information of terminal place group and the number of physical channels of Common Control Channel in the first message, can determine the packet number of described Common Control Channel.
For example, also can adopt following formula to determine the packet number of Common Control Channel:
N
TS＝GroupID?mod?BS_CC_CHANS
Wherein, GroupID represents the corresponding group identification of the identification information of group, and modular arithmetic is carried out in mod representative, and BS_CC_CHANS represents the number of the physical channel of general controls channel.
Between packet number and timeslot number, there is corresponding relation.
230,, according to the identification information of group, determine the corresponding paging packet numbers of identification information of group.
Paging packet numbers is the paging subchannel of corresponding Common Control Channel.In 220, in definite Common Control Channel, there is one or more paging subchannel.In the time there is multiple paging subchannel in Common Control Channel, can adopt multiple paging subchannels are divided into groups, each grouping can be called paging grouping, and, the corresponding paging grouping of terminal of same group.
The corresponding paging packet numbers of identification information of determining group can have various ways.According to identification information and the paging block number of terminal place group in the first message, determine paging packet numbers.Or, according to number of physical channels and the paging block number of the identification information of terminal place group in the first message, the delivery value setting in advance, Common Control Channel, determine paging packet numbers.
For example, can adopt following formula to determine paging packet numbers N
ch:
N
ch＝((GroupID?mod?PresetModValue)mod(BS_CC_CHANS?x?N))mod(Nx?Multiple)
Wherein, GroupID represents the corresponding group identification of the identification information of group, modular arithmetic is carried out in mod representative, PresetModValue is the delivery value setting in advance, and for example PresetModValue can be set in advance as 1000, x and represent multiplying, BS_CC_CHANS represents the number of the physical channel of general controls channel, N is the number of paging block, and Multiple represents certain multiple, as 1,2,1000,10000 etc.
Also can adopt following formula to determine paging packet numbers N
ch:
N
ch＝GroupID?mod(N?x?Multiple)
Wherein, GroupID represents the corresponding group identification of the identification information of group, and modular arithmetic is carried out in mod representative, the number that N is paging block, and Multiple represents certain multiple, as 1,2,1000,10000 etc.
Be understandable that, the identification information of group is for the group at marking terminal place, has the identification information of being permitted various ways and represent group.
For example, the identification information of group can be by MCC (Mobile Country Code, mobile national number), MNC (Mobile Network Code, mobile network No.) and GPIN (Group Identity Number, group identification number) composition, wherein, MCC can be made up of 3 bit digital, identifies uniquely the affiliated country of mobile subscriber.MNC can be made up of two digits, the mobile network belonging to for identifying mobile subscriber.GPIN can be grade long code, for example H1H2H3H4H5H6H7H8H9H10 of ten.
Also for example, the identification information of group also can only be made up of above-mentioned GPIN.For example, or the identification information of group also can be made up of the partial information in above-mentioned GPIN information, H1H2H3, H8H9H10 or H3H4H5H6.
240, on this paging subchannel, send the first paging request message, the first paging request message comprises the identification information of this group.
In order to send the terminal of paging to group place, the identification information that can comprise group in the first paging request message.
The identification information that the first paging request message is carried group has various ways.
For example, the identification information of group can be carried in the mobile logo cell 1 (Mobile Identity 1) of the first paging request message, and carrying out this paging request message of indicating terminal is the paging request to group.
Again for example, the identification information of group also can be carried in other byte of P1 (P1 Rest Octets) cell of the first paging request message, to be set to this paging request message of indicating terminal be the paging request (for example, can be set to NoIdentity) to group to the value of mobile logo cell 1 (Mobile Identity 1) simultaneously.
Again for example, a cell can also be newly set in the first paging request message, the identification information that this cell is used for carrying group (for example, Group Identity), simultaneously, it is the paging request (for example, can be set to No Identity) to group that the value of mobile logo cell 1 (Mobile Identity1) is set to this paging request message of indicating terminal.
Can indicating terminal be the paging for group by the identification information that carries group in the first paging request message, simultaneously by the identification information of group, can prevent that the terminal of monitoring the different groups on same paging subchannel from all responding this beep-page message.
The first paging request message also can be carried the identification information of group by international mobile subscriber group identification information.The form of international mobile subscriber group identification information can adopt the form that is similar to IMSI information.International mobile subscriber group identification information can comprise mobile country code (Mobile Country Code, MCC), mobile network code, MNC (Mobile Network Code, and identification number of mobile subscriber (Mobile Subscriber Identification Number, MSIN) MNC).The form of international mobile subscriber group identification information is different from the form of IMSI information: the information of identification number of mobile subscriber part in IMSI information is adopted to change by MSIN_1 and Group ID two parts form.MSIN_1 is the sequence number of terminal in place group, group's group number that Group ID is terminal.MSIN_1 and Group ID two parts MSIN of compositing terminal altogether, should ensure the uniqueness of MSIN in net.For example, if MSIN_1 part is set to zero entirely, can be used as a kind of mode of the paging of representative to the corresponding group of Group ID in MSIN.For example, international mobile subscriber group identification information can be carried in the mobile logo cell 1 (Mobile Identity 1) of the first paging request message.For example, the identification information part of group can represent with 3 bits or bit still less.Give an example taking MSIN as 9: if the corresponding group identification of the identification information of group as " 149 ", MSIN is " 000000149 ".
In another embodiment of the present invention, by the identification information of group being encapsulated as to the form that is similar to IMSI, can not change the form of existing beep-page message, therefore, lower to the change of existing network, existing terminal also can be identified this beep-page message.
In another embodiment of the present invention, the identification information of group can also be carried by interim group identification information.Interim group identification information can be the interim identification number to each group allocation of network, its form can adopt and be similar to temporarily moved subscriber identification number (Temporary Mobile Subscriber Identify, TMSI) form of information or bag temporarily moved subscriber identification number (Packet Temporary MobileSubscriber Identify, P-TMSI) form of information, be used for identifying group, can correspond to concrete group identification.
Base station sub-system can be determined the time slot of used Common Control Channel by timeslot number corresponding to the packet number of Common Control Channel, can determine to send on the paging of terminal that paging subchannel on should the time slot in Common Control Channel to send by paging subchannel number.
In the present embodiment, base station sub-system can be according to the identification information that receives group, on the corresponding paging subchannel of this group, send the first paging request message, thereby the terminal to this group is carried out paging, thereby avoid network to carry out respectively paging or carry out paging on all paging subchannels all terminals in this group, improve paging efficiency, reduced resource consumption.
