Need to prove, the embodiment of the invention is applicable to the system of various low rate communications, except M2M (Machine to Machine, machine to machine) outside the system, also comprise the system that the person to person communicates by letter and the system of people and machine communication, as long as the user terminal in this system is not high especially to rate requirement.
With an instantiation scheme is described in detail below.
1) base station is divided into different user's groups with the terminal that inserts, and each user's group comprises at least one user terminal.
The base station is according to QoS of survice demand of time sequencing, radio environment information, end user terminal ability information or the user terminal of user terminal connecting system etc., perhaps according to self load condition of base station system, user terminal divided into groups flexibly.The maximum user terminal capacity specifications that the size of grouping and number are prepared to support according to system loading, current access customer number order, teleservice throughput demand and system is determined flexibly.In general, the user terminal that wireless environment is similar or close divides at one group, and the identical or similar user terminal of business demand divides at one group, carries out user grouping according to the time sequencing that enters system, also is the group technology of using always.
Such as, under the more unified situation of user terminal behavior, simply divide into groups according to the time sequencing of user terminal connecting system, organize 50 user terminals as a user, it is full that user organizes, and next access user terminal is just assigned to next user's group; For another example, divide into groups according to the wireless environment (network environment) of user terminal, user terminal identical or close wireless environment can divide at one group.
2) base station is each user's configuration set paging parameters.
When user terminal was divided into groups, the base station disposed by different paging parameters and distinguishes different user's groups.Can distinguish every group of user by different paging groups is set, also can distinguish every group of user, also can distinguish every group of user by the mode of paging group and paging offset combination by different paging offset is set in the paging group.Concrete adopt the sort of method, the business demand of organizing number, every group of number of users, user with the concrete user of current system is closely related.
Wherein, paging parameters comprises paging cycle and paging offset, can utilize " paging cycle+paging offset " to determine the user terminal of current paging, for example, the paging group that is provided with is 50, be respectively group0, group1...group49, the paging cycle of setting is 10s, then in 0-10s, user in the paging group0, in 11-20s, the user terminal in the paging group1, the rest may be inferred; As for paging specifically be which (a bit) user terminal, determine according to paging offset.
3) to the user terminal in each user's group, the base station is default to allow it be introduced into the Idle state, and notice is distributed to their paging parameters.Also be, the base station is after finishing user grouping, promptly sending idle condition message to user terminal indicates each user terminal to be in the Idle state under initial condition, and in message, carry above-mentioned steps 2) be the paging parameters of user's set of dispense under the user terminal, paging parameters comprises paging cycle and paging offset, and user terminal is preserved these parameters.
4) to each user group, the base station is according to the paging parameters initiation packet paging to its distribution, and with user's group in the user terminal that is waken up carry out transfer of data.
The packet paging of base station initiation herein can be that one group of user terminal is unified paging, also can initiate paging one by one to each user terminal.Wherein, one group of user terminal is unified paging further comprise dual mode again, the one, beep-page message carries the ID of one group of user terminal, and this beep-page message is initiated paging to the one or more user terminals in this group simultaneously and is waken up; The 2nd, beep-page message carries the group id of this group user terminal, and expression is initiated paging to all user terminals of this group simultaneously and waken up.Initiate paging one by one is exactly to send a beep-page message at a user terminal at every turn, and indication is initiated paging to this user terminal and waken up.
Pass through said method, the base station can be carried out packet paging according to the business demand of every group of user terminal and be waken up, and carrying out transfer of data with the user terminal that is waken up, all user terminals are at utmost low to reduce and system unnecessary mutual the energy consumption of saving user terminal thereby allow.
