Description
Technical field
The present invention relates to wireless communication technology field, relate in particular to a kind of cell reselection and resident method, terminal, network equipment and system.
Background technology
In Long Term Evolution (LTE R11) multimedia broadcast multi-broadcasting business (MBMS, the Multimedia Broadcast Multicast Service) system of the 11st version, in order to keep the continuity of MBMS business, current mechanism is as follows:
For the terminal under connected state (that is: the terminal under RRC connected pattern), introduce MBMS business and receive indication.In terminal, wish to receive MBMS business or interested MBMS business at hand time, terminal can receive indication informing network side by MBMS business, and (MBMS business receives in indication and can comprise, whether MBMS service priority is higher than unicast service, and the frequency information of interested MBMS business).(network side refers to network element to network side, as: the evolution base station in LTE system (eNB), multimedia broadcasting and multicast coordination entity (MCE) etc.) after receiving MBMS business reception indication, just can understand the MBMS service related information of terminal, and can, according to the strategies such as load condition of network side, determine whether this MBMS business is switched to MBMS carrier wave.
For the terminal under Idle state (that is: the terminal under RRC Idle pattern), according to cell reselection criterion before, the frequency priority that terminal issues according to network side is carried out community selection and resident.But network side is not also known concrete resident frequency and the cell information of terminal, therefore, in R11, has introduced the preferential criterion of selecting of MBMS frequency, specific as follows:
Introduce new system broadcast information (can with SIB14 or SIB15 carrying), carry service area indication (MBMS SAI, MBMS Service area identity, can be referred to as SAI) and corresponding frequency information above.Concrete, in this new system broadcast message, can carry the SAI of this community (that is: current area), and the SAI of adjacent alien-frequency district and frequency information, be used for indicating this community which belongs to/which SAI, and which the adjacent frequency of this community belongs to/which SAI.
If comprise the SAI of the interested MBMS business of terminal in SIB14, allow the frequency that terminal is limit priority by the set of frequency of indicating in SIB14, preferentially select corresponding frequencies to carry out community selection and resident.
When network side has been disposed a plurality of carrier waves, and only at one or several carrier waves (MBMS carrier wave, can be understood as the carrier wave that has carried MBMS business) on when MBMS business is provided, for having resided in subscribing to of non-MBMS carrier wave the terminal of MBMS business (being called for short MBMS terminal), the preferential criterion of selecting of MBMS frequency of introducing according to above-mentioned R11, or may lose the chance that receives MBMS business, thereby the decline that causes user to experience.This be because:
Terminal, according to time started and the end time (or the time started of each MBMS business and duration) of electronic program list (ESG)/each MBMS business that unified business guide (USD) above identifies, can attempt receiving MBMS business in advance.
The method of the frequency that certain frequency of terminal judges is its MBMS business interested place can be: 1) terminal reads USD, determine the relevant information (relevant information that comprises a plurality of MBMS business on USD of its MBMS business interested, the relevant information of each MBMS business at least comprises: the sign TMGI of MBMS business, time started/duration, the SAI belonging to); 2) terminal read SIB14(take with SIB14, carry new system broadcast information and describe as example), determine which this community and/or neighbor cell belong to/which SAI overlay area; 3) terminal compares USD and SIB14, can find whether to have in SIB14 the SAI of self interested MBMS business, and can have the SAI of self interested MBMS business in SIB14 time, determine corresponding frequency information, and think the frequency that this frequency is its MBMS business interested place.
Now, terminal can be classified the frequency at own interested MBMS business place as limit priority automatically, adopts the existing community of R9/R10 to select and cell reselection principle, carries out community selection/reselection and resident.
For example, terminal finds that certain side frequency has carried its interested MBMS business, wish, by the resident community to this side frequency of cell reselection, can specifically comprise: 1) terminal reads USD and SIB14, find that in SIB14, certain frequency has its interested MBMS business; 2) terminal is made as limit priority by this frequency; 3) terminal adopts the community of R9/R10 to select and cell reselection rule, carries out cell reselection; 4), if the signal quality of the community of this frequency meets the resident condition in community, terminal can arrive the community of this frequency by cell reselection, and resides in the community of this frequency; 5) terminal reads its interested MBMS business in this frequency cells.
If but terminal poor signal or other reasons and cause this frequency cells not meet cell reselection and resident condition in this frequency, terminal can be abandoned the resident trial in this frequency, and attempt to the frequency of inferior priority, and gravity treatment and reside in the community of time priority frequency, cause thus terminal to lose the chance that receives MBMS business.
; according to the scheme of prior art; when terminal causes this frequency cells not meet the resident condition in community at the upper poor signal of the frequency (limit priority) at its MBMS business interested place or other reasons; terminal can, according to priority setting, be carried out cell reselection to other frequencies (frequency at non-its MBMS business interested place).Ruo Gai community meets resident condition, terminal is understood gravity treatment and is resided in this community, and according to the cell reselection rule of R9/R10, carries out cell reselection, can be understood as terminal, re-starts community and selects during lower than threshold value at the RSRP/RSRQ of its resident community signal quality.May cause very much thus terminal to lose the chance that receives MBMS business.

Below in conjunction with Figure of description and each embodiment, the present invention program is described.
Embodiment mono-,
The embodiment of the present invention one provides a kind of cell reselection and resident method, and the steps flow chart of the method can as shown in Figure 1, comprise:
Whether step 101, the MBMS business that terminal judges is to be received finish.
Due to terminal can determine the MBMS business that it is to be received end time (as, by read electric programme (ESG)/unified business guide (USD), determine), and if the MBMS business that terminal need to receive has finished, even terminal gravity treatment the resident community to using its MBMS business place frequency to be received, also cannot realize the reception of MBMS business, therefore, in the present embodiment, before the MBMS business that terminal can need to receive at it not yet finishes, the step below the present embodiment is carried out in continuation, attempt gravity treatment the resident community to using its MBMS business place frequency to be received, thereby after guaranteeing the resident Zhi Gai of terminal community, can continue to receive its MBMS business to be received, guarantee the reception of user's MBMS business, improve user's business experience.
The prerequisite that terminal need to be carried out this step (the present embodiment scheme) is, terminal resides in the community failure of its MBMS business interested place frequency, and gravity treatment also resides in the community of non-its MBMS business interested place frequency.
Therefore, this step can comprise, terminal in residing in the process of community, judge MBMS business to be received whether finish the frequency used ，Gai community non-described in MBMS business place frequency to be received.
Certainly, in this step, except judging whether MBMS business to be received finishes, whether terminal can also further judge self needs to continue to receive this MBMS business to be received, if determine that self is without continuing to receive this MBMS business to be received, also without the step of continue carrying out below the present embodiment, without gravity treatment the resident community to using its MBMS business place frequency to be received, and can further judge self need to continue to receive this wait receive MBMS business time, the step below the present embodiment is carried out in continuation, attempt gravity treatment the resident community to using its MBMS business place frequency to be received.
Whether step 102, terminal judges can gravity treatment the resident communities to MBMS business place frequency to be received described in use.
If terminal is determined its MBMS business that need to receive and is not yet finished, or further determine and self need to continue to receive this MBMS business to be received, the signal sending under MBMS business place frequency described to be received that measurement receives, judges whether that the community of MBMS business place frequency to be received described in use meets cell reselection and/or resident condition.
Concrete, can be understood as, if terminal is determined its MBMS business that need to receive and is not yet finished, or further determine and self need to continue to receive this MBMS business to be received, terminal is using MBMS business place frequency described to be received as limit priority frequency, the signal sending under MBMS business place frequency described to be received that measurement receives, judges whether that the community of MBMS business place frequency to be received described in use meets cell reselection and/or resident condition.
In the present embodiment, triggering terminal carries out cell reselection and resident condition can be: described in use, the community of MBMS business place frequency to be received meets cell reselection condition (described cell reselection condition, refer to the cell reselection criterion that need to meet agreement regulation, referring to 36.304 agreements (V10.5.0)), can be understood as the signal quality of community of MBMS business place frequency to be received described in use higher than the signal quality of community, the current place of terminal, and the signal quality of community of MBMS business place frequency to be received and the threshold value that the difference between the signal quality of community, the current place of terminal is greater than setting described in using, or, triggering terminal carries out cell reselection and resident condition can be also: described in use, the community of MBMS business place frequency to be received meets the resident condition in community, can be understood as the signal quality of community of MBMS business place frequency to be received described in use higher than the threshold value of setting.
In sum, even if it is fine to can be understood as the signal quality of community, the current place of terminal, according to the regulation of prior art, not meeting terminal startup cell reselection (does not meet terminal and carries out signal measurement, judge whether that other communities meet cell reselection condition) condition, but in the present embodiment, as long as terminal is determined its MBMS business that need to receive and is not yet finished, or further determine and self need to continue to receive this MBMS business to be received, the signal sending under MBMS business place frequency described to be received will triggering terminal measurement receiving, cell reselection and resident is carried out in trial.
Certainly, terminal need to be measured the signal sending under MBMS business place frequency described to be received receiving under the prerequisite that meets existing measurement criterion.
The signal sending under MBMS business place frequency described to be received that terminal measurement receives can be to carry out according to the parameter of terminal self definition, can be also the control that is subject to network equipment, and the parameter issuing according to network equipment is carried out.
For example, the maximum that terminal can be, but not limited to set according to self is measured at least one in number of times, measuring intervals of TIME and the longest Measuring Time, measures the signal sending under MBMS business place frequency described to be received receiving.The described maximum number of times of measuring can be understood as from step 101, terminal is determined the MBMS business that self need to receive and is not yet finished, or further determine the moment that self need to continue to receive this MBMS business to be received, carry out the maximum times of measuring the signal sending receiving under MBMS business place frequency described to be received.Measuring intervals of TIME can be understood as interlude length between any twice measurement.The longest Measuring Time can be understood as from step 101, terminal is determined the MBMS business that self need to receive and is not yet finished, or further determine the moment that self need to continue to receive this MBMS business to be received, terminal is carried out the operation of measuring the signal sending receiving under MBMS business place frequency described to be received within this period.Certainly, the above-mentioned parameter that terminal is set need to meet the measurement demand of terminal to the current community self residing in.
And for example, be illustrated in figure 2 the mutual schematic diagram between terminal and network equipment, terminal can, according to the measurement parameter of the network equipment configuration receiving, be measured the signal sending under MBMS business place frequency described to be received receiving.Described measurement parameter can be, but not limited to comprise at least one in the maximum measurement time slot of measuring number of times, measuring intervals of TIME, the longest Measuring Time and different-frequency measure.And wherein, the configuration by network equipment to the measurement time slot of different-frequency measure, can be so that the signal of terminal MBMS business place frequency to be received described in measuring in the measurement time slot of configuration reduces the impact of the signal measurement of the community that terminal is resided in.
Concrete, network equipment can pass through system broadcast message, if SIB14 is to terminal sending measuring parameter.If the signal sending under MBMS business place frequency described to be received that terminal receives according to the measurement parameter measurement of network equipment configuration, the operation that can be understood as the signal sending that terminal measurement receives under MBMS business place frequency described to be received is that terminal is initiatively carried out, and measure according to the measurement parameter of network equipment configuration, also can be understood as terminal according to the measurement parameter of the network equipment configuration receiving, the measurement of triggering to the signal sending under MBMS business place frequency described to be received receiving, in step 101, terminal can initiatively judge whether MBMS business to be received finishes, also can be when receiving the measurement parameter of network equipment configuration, triggering judges whether MBMS business to be received finishes.
Certainly, when terminal receives the measurement parameter of network equipment configuration, can also send feedback information to network equipment, described feedback information is used to indicate described terminal and whether receives the measurement parameter that described network equipment issues.Whether informing network side apparatus self has received the measurement parameter that network equipment issues, thereby make network equipment to understand in time terminal according to feedback information, whether has received the measurement parameter self issuing.
If the community of MBMS business place frequency to be received meets cell reselection and/or resident condition described in the definite existence use of terminal, terminal can be carried out cell reselection Zhi Gai community, thereby can receive MBMS business in this cell relays continued access, avoid missing the reception of MBMS business, guarantee the success rate that MBMS business receives.
