Description

Method and device that a kind of beep-page message sends

Technical field

The present invention relates to moving communicating field, particularly, the present invention relates to method and device that a kind of beep-page message sends.

Background technology

Move the developing direction that becomes modern communication technology with the broadband, 3GPP (3rd GenerationPartnership Project, third generation partner program) be devoted to the evolution of 3G system, target is development 3GPP wireless access technology towards high data rate, lowly postpones and optimize the evolution of packet data application direction.3GPP requires peak rate than LTE (Long Term Evolution, Long Term Evolution) system huge raising to be arranged in LTE-A (Long Term Evolution-Advanced, Long Term Evolution is senior) system, requires to reach descending 1Gbps, up 500Mbps.On single carrier wave, can't satisfy this demand, therefore introduce CA (Carrier Aggregation, carrier aggregation) technology in the LTE-A system.The CA technology is meant: under same eNB, having overlapping covered a plurality of carrier waves and concentrate in together on physical space, is a UE (User Equipment, subscriber equipment) service, so that UE to be provided required service rate simultaneously.Each carrier wave that participates in CA is called CC (Component Carrier, member carrier).Simultaneously, in the LTE-A system, there is and has only a carrier wave each sub-district under the definition eNB.So carrier aggregation also can be understood as a UE and uses the resource of a plurality of sub-districts under the eNB and network to carry out transfer of data simultaneously.

In order to guarantee compatible LTE UE, the carrier wave maximum bandwidth of each sub-district of LTE-A system requirements is no more than 20MHz.As shown in Figure 1, be the CA technology schematic diagram of LTE-A in the prior art.ENB carries out transfer of data with UE simultaneously on 4 CC, to improve the UE of system throughput.

In the cell mobile communication systems, the Mobility Management Strategy that network adopts for idle UE is based on the mobile management of UE control.Network is divided into several TA (Tracking Area, lane place), and each TA is made up of a plurality of adjacent sub-districts.TA uses TA ID to identify, and TA ID sends in the broadcast of sub-district.

Be in the UE of idle condition for each, network is specified a TA list for it, comprises one or more TA ID among the TA list.When idle UE carries out cell selecting or gravity treatment is resident behind a new sub-district, its broadcast message according to persistent district is obtained the ID of the TA of institute's persistent district ownership, if this TA ID belongs to the TA list of network for its configuration, then UE does not do operation; Otherwise this UE need pass through TAU (Tracking Area Update, location area updating) process and report present located TA to network.By such mechanism, network just can be to the residing geographical position of idle UE in the enterprising line trace of TA list rank.

UE carries out process that TA upgrades as shown in Figure 2, and this process is used for the TA that UE upgrades current registration.When UE enters a new TA, will trigger this process.

UE triggers the TA renewal process by sending location area updating request (TA UPDATING REQUEST) message to network, and the user sends the TA update inquiry information and has old TMSI, old RAI, and old TMSI signature, parameters such as TA updating type are given network.

If network has been accepted the TA update request of UE, will upgrade to UE response position district and accept (TAUPDATING ACCEPT) message.After UE receives this message, will carry out and the similar processing of the heavy assigning process of TMSI according to parameters such as incidental RAI, TMSI or IMSI in the message elements; If network can not be accepted the TA update request of UE, will send location area updating refusal (TAUPDATING REJECT) message to UE.After UE receives this message, will store Reason For Denial, wait for that the signaling by network-triggered connects release.

Because the mobility of UE, called UE may be in any position in the network before communication.Cell mobile communication systems use paging is initiated the calling to idle UE.Mobility Management Strategy based on UE control has determined network can only know the position of UE in TA list rank.Therefore, when network needed paging UE, its beep-page message also can only send on all sub-districts in the whole TA list.Usually, comprise dozens or even hundreds of sub-district among the TA, obviously, send identical beep-page message simultaneously in all sub-districts in TA list and need consume a large amount of interface-free resources.

The process of transmitting of beep-page message is as follows:

Core net node generates beep-page message, comprises following information in the beep-page message: the sign of paged UE; The pairing TA list of paged UE;

Core net node is according to the pairing TA list of paged UE, and the corresponding relation between TA and the eNB, determines which eNB beep-page message need send to, and then, beep-page message is sent to the eNB of correspondence with the form of S1-AP message;

ENB is according to the TA list information received, and the relation that has the correspondence of sub-district and TA under its command determines beep-page message need send in which sub-district.ENB is the eat dishes without rice or wine transmission of beep-page message in described sub-district with the S1-AP message conversion of receiving.In the beep-page message of eating dishes without rice or wine to send, comprise following information: the sign of paged UE.

In said process, the corresponding relation between core net node record UE and the TA list, and the corresponding relation between TA and the eNB, the eNB record has the relation of the correspondence of sub-district and TA under its command.

For the LTE-A UE that is in connection (RRC CONNECTED) state, it can use the resource of a plurality of cell/carriers simultaneously, and network can be according to the requirement of customer service speed, and the resource of dispatching one or more carrier wave is this UE service.

For the LTE UE that is in connection (RRC CONNECTED) state, it can only use the resource of a cell/carrier a moment, and promptly can only to dispatch the resource of a carrier wave be this UE service to network.

For the LTE UE and the LTE-A UE that are in free time (RRC IDLE) state, all only can select a sub-district to carry out resident.Promptly only can monitor the paging and the broadcast of a carrier wave.

In order to reduce under the idle condition, UE carries out the frequency of TAU, generally, under the LTE-AeNB, has overlapping covered a plurality of LTE-A sub-district and can be put under a TA on physical space.But this TA division rule will cause when sending paging, and network can send paging simultaneously having on a plurality of sub-districts of identical coverage, causes the wasting of resources.

For LTE UE, the above-mentioned wasting of resources is inevitable.With regard to LTE UE, sub-district that can not be resident under idle condition, also unavailable this sub-district under connection status.In other words: sub-district that can not be resident under idle condition is exactly incompatible sub-district or disabled sub-district for LTE UE.

For the UE of LTE-A, situation is just different.Even a CA sub-district, idle condition UE can only be resident on a sub-district, when it forwards under the connection status, this UE also can use under the service eNB, can with the resource of all carrier wave/sub-districts of persistent district carrier aggregation.

With Fig. 1 is example, because the restriction of UE ability, LTE UE can see in same geographical position and have 4 different sub-districts of center frequency point that it can only use the resource of a sub-district in 4 sub-districts simultaneously.For the UE that is in idle condition,, when it forwards connection status to and transfers Active to, also can only use the resource on the carrier2 if it has resided on 2 respective cell of carrier.If it is resident that carrier3 institute respective cell does not allow to be in the idle LTE UE of idle condition, then when forwarding connection status to, UE transfers to when activating, can not use resource on the carrier 3.But for LTE-A UE, be 4 sub-districts that exist center frequency point different in same geographical position equally though it sees, it can use the resource of whole 4 sub-districts simultaneously by the CA technology.For the UE that is in idle condition, if it has resided on 2 respective cell of carrier, when it forwards connection status to, not only can use the resource of carrier2, can also use the resource of three sub-districts by the CA mode simultaneously.

Therefore, for the communication system of LTE and LTE-A coexistence, need to allow LTE UE to reside in more sub-district, so that LTE UE can use the resource of respective cell; Need to consider only to allow LTE-A UE to reside in less sub-district, to reduce the expense that LTE-A UE is sent paging.The persistent district set that LTE is different with LTE-A UE has caused different beep-page message range of transmissions.

Thus, be necessary to propose a kind of technical scheme, exist under the situation of CA, solve eNB and realize LTE UE and LTE-A UE are gathered the problem that sends paging at different districts.

In an embodiment of the present invention, first system includes but not limited to Long Term Evolution LTE system, and second system includes but not limited to the senior LTE-A of Long Term Evolution system, and for example, the later evolution version of LTE also is applicable to the present invention.The following examples are example explanation the present invention with LTE or LTE-A system all, and obviously, application of the present invention is not limited to said system.

As described in Figure 3, the flow chart for the beep-page message sending method may further comprise the steps:

S101:eNB is indicating TA ID n2 to the UE of first system broadcasting TA ID n1 and on set of cells 2 to second UE of system on the set of cells 1.

In step S101, base station eNB on the set of cells 1 that has the sub-district under its command to LTE user equipment (UE) broadcast location area TA ID n1 and having under its command on the set of cells 2 of sub-district to LTE-AUE indicating positions district sign TA ID n2.

Wherein, LTE UE resides in a sub-district in the described set of cells 1, and LTE-A UE resides on the sub-district of set of cells 2.Two set of cells can partially overlap, all overlap or not overlap fully.Each UE resides on the sub-district according to the type of oneself, and this sub-district affiliated subdistrict set should conform to the type of this UE.Promptly in above-mentioned steps, the user equipment (UE) of first system can only reside in the sub-district of broadcasting TA ID n1; The user equipment (UE) of second system resides in the zone that can receive TA ID n2.

Be exemplified below in conjunction with Fig. 1: on all 4 sub-districts, the TAID that eNB broadcasting LTE UE can use is called TA ID n1.LTE UE can reside on any one sub-district; LTE-A UE obtains the TA ID that can be used for LTE-A UE, is called TA ID n2; In the present embodiment, LTE-A UE is only to reside on carrier wave 4 corresponding district.

Therefore, the member carrier of the UE that set of cells 2 is formed is any one or a plurality of member carrier in the set of cells 1, be that set of cells 2 is less than set of cells 1 and is a subclass in the set of cells 1, for example, set of cells 2 only comprises a member carrier when being a sub-district, be four carrier wave 4 corresponding district in the carrier wave.Obviously, set of cells 2 also can be included as the another one carrier cell that is different from above-mentioned a plurality of carrier cells, is specifically designed to the member carrier sub-district into LTE-A UE service.

Wherein, comprising to LTE-A UE indicating positions district sign TA ID n2 on the set of cells 2: eNB broadcasts TA ID n2 to LTE-A UE on set of cells 2.For example on carrier wave 4, broadcast TA ID n2 to LTE-AUE.

Respective cell set 2 for any one or a plurality of sub-district in the described set of cells 1, for example be under the situation of four carrier wave 4 corresponding district in the sub-district, on the specific carriers 4 to LTE-A UE indicating positions district sign TA ID n2 can also be: the TA ID n1 that TA ID n2 on the carrier wave 4 and LTE UE broadcast on carrier wave 4 exists fixing deviant offset, i.e. TA ID n2=TA ID n1+offset.

Wherein, the numerical value of fixing deviant offset in the broadcast of set of cells 2, carrying, i.e. broadcasting on carrier wave 4, or the fixed value of in agreement, stipulating.

S102:eNB receives the location update message TAU that the UE of first system and second system sends and is transmitted to core net.

In step S 102, eNB receives the location update message TAU of LTE UE and LTE-A UE transmission respectively and is transmitted to core net, and location update message TAU comprises the Location Area Identification TAID of UE, promptly comprises TA ID n2 and two kinds of Location Area Identification of TA ID n1.Usually, LTE UE belongs to different lane place set with the TA ID that LTE-AUE sends by TAU message.Two peer nodes of TAU process are UE and core net, and eNB just does transparent forwarding between the two.When UE carries out TAU, LTE UE will report TA ID n1 to core net, and LTE-A UE will report TA ID n2 to core net; Core net initiates the eNB at TAU place according to UE and the station location marker information of reporting is UE configuration TA List, and TA list is sent to UE.

S 103:eNB determines the transmission cell range of beep-page message, and sends beep-page message at corresponding set of cells.

(1) core net determines certain UE of paging, finds the TA List of this UE correspondence;

(2) the core net information such as TA List, paging reason that will desire the identification information of UE of paging and this UE correspondence send to eNB in S1-AP message; The eNB that receives this S1-AP has in the sub-district that following feature: eNB has under its command and has at least to be arranged in the TA that TA list writes down;

(3) eNB determines and send beep-page message in which or which sub-district according to the TA list that receives;

(4) send beep-page message in the sub-district that eNB determines in (3), carry the identification information of paged UE in the beep-page message, paging reason etc.

In the present invention, paging is continued to use said process.

Wherein, because what the TA list of LTE UE and LTE-A UE comprised is respectively above-mentioned two class set of cells, so, can realize that eNB sends beep-page message to LTE UE to LTE UE and LTE-A UE sending beep-page message: eNB on the different set of cells on set of cells 1, eNB sends beep-page message to LTE-A UE on set of cells 2.Be exemplified below in conjunction with Fig. 1: in all 4 sub-districts, eNB sends beep-page message to LTE UE; ENB only sends beep-page message to LTE-A UE in carrier wave 4 corresponding district.

Therefore, by said method, be two groups of positional informations signs of the cell configuration in the set of cells 2, one group for LTE UE use, and one group is used for LTE-A UE.UE reports the corresponding position information sign according to the type of oneself in the TAU process.Like this, when core net sent paging, eNB can be according to receiving the range of transmission of determining beep-page message from the TA among the TA list in the S1-AP message of core net.
