Description

Isomery cellular network multimode list is treated residence reselecting, the Apparatus and system of terminal

Technical field

The present invention relates to wireless communication technology field, relate in particular to residence reselecting, Apparatus and system that a kind of isomery cellular network multimode list is treated terminal.

Background technology

Isomery cellular network refers to that the cellular mobile communication networks of a plurality of different access technologies that overlay area is overlapped is formed, provide the wireless communication system of plurality of access modes for user.Along with the fast development of cellular mobile communication technology, the communication system that presents isomery cellular network form will become the trend that future network is disposed.Multimode list treats that terminal refers to the radio frequency access module that is equipped with a plurality of different access technologies, can reside in different access networks and accept service, and the terminal of switching between different access networks.At present, second generation mobile communication system (2G) and 3-G (Generation Three mobile communication system) (3G) are commercial on a large scale in the whole world.The Long Term Evolution (LTE) that third generation partner program (3GPP) is formulated is the standard of next generation mobile communication network.Present stage is because 2G and 3G network have occupied the lower frequency range of frequency, so the deployment of LTE can only carry out in the higher frequency range of frequency, and this will cause LTE radius of society to be less than the radius of society of 2G and 3G.Compare all standing network of 2G and 3G, LTE is very possible only as the network covering in hot spot region at the network design initial stage, and multimode list treats that terminal will carry out gravity treatment or switching in turnover LTE overlay area between LTE and 3G/2G network.Existing 2G and 3G network have a large amount of storage users and basic network equipment, adopt the form of isomery cellular network to dispose next generation network, based on existing 3G system, carry out evolution (for example evolving to TD-LTE from TD-SCDMA), contribute to realize the smooth upgrade of network, save networking cost, reduce the difficulty of operator's networking.

Aspect business, LTE is a full packet data network, in Evolved Packet Core (EPC), there is not circuit domain, cannot realize the speech business of traditional approach, can only be by providing VoIP(Voice over IP based on IP Multimedia System (IMS)) business.And at the LTE networking initial stage, operator possibly cannot provide VoIP business by LTE, therefore can only provide speech business by existing 3G/2G core net circuit domain, need to take some core network technology to provide speech business (for example circuit domain dropping technology) for LTE user.And, compare 3G and 2G network, the message transmission rate that LTE network support is higher, has stronger data service ability.User, when initiating data service, should preferentially adopt the LTE network of function admirable, only in the time cannot using LTE network, just uses 3G or 2G network initiated data business.

In isomery cellular network, the cell reselection behavior of idle mode terminals is recurrent.When terminal and base station do not exist Radio Resource control (RRC) to be connected, this terminal is called the terminal of idle pulley.Terminal in idle pulley, can, according to agreement regulation, measure the signal strength signal intensity of its each access network receiving, and when signal conditioning meets reselection criterion, the network concurrent that will initiatively leave current access play the access request to other networks.This process does not relate to the signalling interactive process of core net, is the behavior of initiatively being initiated by terminal.The TD-LTE/TD-SCDMA isomery cellular network of take is example, and TD-LTE network may be deployed in inner city and large-scale office space etc.In the multimode list of idle pulley, treat that terminal resides in TD-SCDMA network outside TD-LTE overlay area, and, in moving to gradually the process of inside, TD-LTE overlay area, all the time monitor the received signal strength of TD-LTE network, when the signal strength signal intensity of TD-LTE network reaches certain thresholding, will be opened to the cell reselection of TD-LTE network and be linked into LTE network; When this terminal moves within TD-LTE overlay area outside overlay area, along with the received signal strength of TD-LTE network declines gradually, when meeting reselection criterion, terminal will be initiated to the cell reselection of TD-SCDMA network.

The residence reselecting of stipulating in agreement is at present the reselecting method based on priority, by by all alternative access networks according to prioritization, and complete cell reselection with reference to cell reselection R criterion.In real network, the TD-LTE network carrying covering as focus huge traffic carrying capacity.If the gravity treatment behavior from the TD-SCDMA network terminal is not limited, very easily there is TD-LTE network over loading, thereby affected the service quality (QoS) of other users in TD-LTE overlay area.

Embodiment of the present invention said method, Apparatus and system technical scheme has following beneficial effect: because adopt the system information block that obtains Access Network broadcast, judge that in described system information block, whether comprising gravity treatment controls designator, if judge, in described system information block, comprise gravity treatment and control designator, the mode of the threshold value of the Access Network of the Target cell of employing replacement terminal gravity treatment is carried out the technological means of cell reselection, so reached following technique effect: the mode based on system information block has realized the switching of the cell reselection scheme of terminal, be easy to be incorporated in network and realize with existing protocol knot, improved cell reselection scheme can be avoided network over loading effectively, guarantees the QoS of user in Access Network K, adopt this scheme can not have influence on the user of high priority Access Network, this scheme is compared existing single cell reselection R criterion, and reselection modes is more flexibly provided, and has promoted network and has tackled and eliminate the ability of transshipping.

In order clearly to show technical scheme of the present invention, below lift application example and describe:

First the present invention analyzes the R criterion of the cell reselection of regulation in 3GPP agreement TS 36.304.This criterion sorts each Access Network according to priority.

According to agreement regulation, terminal is opened cell reselection for the community of high priority Access Network (priority is higher than the Access Network of current Access Network) and need to be met, at time period Treselection rATin, the community received signal power of this high priority Access Network is greater than the thresholding 1 of this high priority Access Network; Terminal is opened cell reselection for the community of low priority Access Network and need to be met, at time period Treselection rATin, the community received signal power of this low priority Access Network is greater than the thresholding 1 of this low priority Access Network, and the community received signal power of current Access Network is less than the thresholding 2 of current Access Network.Wherein RAT represents different wireless access technologys.

Fig. 3 has shown the concrete steps flow chart of the R criterion of the cell reselection of regulation in 3GPP agreement TS 36.304, comprises the steps:

Step 301, terminal obtains the described thresholding 1 of each Access Network and the prioritization of thresholding 2 and each Access Network by mode pre-configured or read system information piece.

Step 302, the Access Network of Target cell of judgement gravity treatment and the priority relationship between the Access Network of current area.If the priority of the Access Network of Target cell, higher than the priority of the Access Network of current area, performs step 303; If the priority of the Access Network of Target cell, lower than the priority of the Access Network of current area, performs step 304.

Step 303, judges whether to meet following condition, at time period Treselection rATin, the community received signal power of this high priority Access Network is greater than the thresholding 1 of this high priority Access Network.If meet, execution step 305; If do not meet, execution step 306.

Step 304, judges whether to meet following condition, at time period Treselection rATin, the community received signal power of this low priority Access Network is greater than the thresholding 1 of this low priority Access Network, and the community received signal power of current Access Network is less than the thresholding 2 of current Access Network.If meet, execution step 305; If do not meet, execution step 306.

Step 305, terminal is opened to the cell reselection of Target cell.

Step 306, terminal is not opened to the cell reselection of Target cell.

The method is not considered, in real network, for example, in TD-LTE/TD-SCDMA isomery cellular network, the TD-LTE network carrying covering as focus huge traffic carrying capacity, if the gravity treatment behavior from the TD-SCDMA network terminal is not limited, very easily there is TD-LTE network over loading, thereby affected the service quality (QoS) of other users in TD-LTE overlay area.Propose by this improved isomery cellular network multimode list and treat the residence reselecting of terminal.

The first application example:

Below in conjunction with Fig. 4, illustrate that improved isomery cellular network multimode list treats the residence reselecting of terminal.Usually, suppose for the community of Access Network K and carry out gravity treatment control, to alleviate the traffic carrying capacity of Access Network K, avoid network over loading, guaranteed qos.

The realization mechanism of the method is as follows: for the terminal of low priority Access Network, should increase its gravity treatment to the difficulty of Access Network K, reduce the number of the terminal of cell reselection in low priority Access Network, that be opened to Access Network K; For the terminal of Access Network K, should reduce its gravity treatment to the difficulty of low priority Access Network, increase the number of the terminal of cell reselection in Access Network K, that be opened to low priority Access Network.And in order not affect high priority Access Network, the situation for the terminal gravity treatment of Access Network K to the terminal gravity treatment of high priority Access Network and high priority Access Network to Access Network K without any changes.When network even running, terminal adopts the R criterion in agreement to carry out cell reselection; When network traffic increases sharply, while there is overload risk, terminal should be enabled improved residence reselecting; When network traffic declines and recover steady, terminal reactivates R criterion and carries out cell reselection.

Thresholding 1 and the thresholding 2 of note Access Network K are respectively Thresh rAT K, 1and Thresh rAT K, 2, the network identity that wherein K is Access Network, below similar, repeat no more.The received signal power of note Access Network K is R rAT K.Definition is on the occasion of thresholding increment Delta T 1with Δ T 2.Definition gravity treatment probability function P (R rAT K, Δ T 1).Remember that certain low priority Access Network is Access Network D, certain high priority Access Network is Access Network G.

As shown in Figure 4, the method includes the steps of:

Step 401, there is overload or has overload risk in network judgement Access Network K.In system information block, broadcast gravity treatment and control designator.Terminal is enabled improved residence reselecting and is carried out cell reselection.

Step 402, for the terminal of Access Network D, adopts new thresholding Thresh rAT K, 1+ Δ T 1replace Thresh rAT K, 1, for this terminal gravity treatment, arrive Access Network K.

Step 403, for the terminal of Access Network K, adopts new thresholding Thresh rAT D, 1-Δ T 2replace Thresh rAT D, 1, and, with probability P (R rAT K, Δ T 1) gravity treatment is to low priority Access Network D.

Step 404, the overload of network judgement Access Network K is eliminated.In system information block, gravity treatment control designator is cancelled in broadcast.Terminal reactivates R criterion and carries out cell reselection.

In step 401 and step 404, system judges the whether evaluating in overload of Access Network K, includes but not limited to: the load condition of the node pool of core network district of the attached users of the occupancy of the Traffic Channel of Access Network K, Access Network K and traffic carrying capacity, Access Network K (such as the Mobility Management Entity Chi Qu of the MSC pool district of 3G core net and Serving GPRS Support Node Chi Qu, 4G core net) etc.

In step 401, the network identity that designator should comprise Access Network K is controlled in the gravity treatment of broadcasting in system information block.

In step 403, probability P (R rAT K, Δ T 1) expression formula as follows:

P ( R RAT K , &Delta;T 1 ) =

1 , R RAT K &le; Tharesh RAT K , 2 1 - R RAT K - Thresh RAT K , 2 &Delta;T 1 , Thresh RAT K , 2 < R RAT K < Thresh RAT K , 2 + &Delta;T 1 0 , R RAT K &GreaterEqual; Thresh RAT K , 2 + &Delta;T 1

In order to facilitate technical staff to understand better this method, the R criterion of this method and cell reselection is contrasted: in the judgment condition of the step 404 of the R of cell reselection criterion, that is, and at time period Treselection rATin, the community received signal power of low priority Access Network is greater than the thresholding 1 of this low priority Access Network, and when the community received signal power of current Access Network is less than the thresholding 2 of current Access Network, terminal is opened to the gravity treatment of Target cell, this is equivalent to, when the community received signal power of low priority Access Network is greater than the thresholding 1 of this low priority Access Network, terminal is with probability P (R rAT K, 0) and be opened to the cell reselection of Target cell, wherein,

P ( R RAT K , &Delta;T 1 ) =

1 , R RAT K &le; Thresh RAT K , 2 0 , R RAT K > Thresh RAT K , 2

This expression formula shows, the R criterion of cell reselection is the special case that improved isomery cellular network multimode list is treated the residence reselecting of terminal.Configuration Δ T 1=0 and Δ T 2=0, while carrying out gravity treatment control for Access Network K, improved isomery cellular network multimode list treats that the residence reselecting of terminal deteriorates to the R criterion of cell reselection.
