Wherein, the base station RAT that UE is currently resident is likely to be multiple, such as present dual-mode dual-standby 3G and GSM, and UE can be with GSM and 3G are resided in simultaneously.When initiating voice service, it can directly select and be accessed under GSM standard.

First specific transactions are referred to as small data quantity business, and the second specific transactions are referred to as big data Amount business.

Small data quantity business is it is characterized in that average demand rate is smaller and sudden strong, data packet lesser business mostly. It is background service and instant messaging than more typical small data type of service.Its feature is as follows:

Background service (Background business):

For Background business, refer to that service application is in the open state, but there is no real business datums A kind of situation, i.e. service application software may be and opens, but business is in unactivated state, data packet at this time mainly by The composition such as some some heartbeat packets triggered to guarantee the connection between user equipment and server.Such business characteristic is such as Under:

Heartbeat packet comprising exchange and the data packet (such as maintaining to connect by firewall) for keeping Channel Activation, electronics It the state-detection of mail and chat server and seeks, is possibly used for location-based business (Location Based Service, LBS) location updating, certain cloud computing interaction；

Business is usually to be automatically generated by the server of application or application connection, is not related to the interaction with user equipment；

Business is usually symmetrical and relevant；

Long-term average transmission rate (uplink and downlink is total) is about the magnitude of 5-250 bytes-per-second；

Equispaced between data burst is larger；

IP data package size is mostly smaller；

There is similar periodic feature.

Instant messaging (IM business):

For also can be with Background business in always on IM business.Such business characteristic is as follows:

The characteristic of instant messaging is interactive to carry out user with relatively low data volume；

Data package size is usually smaller and infrequently；

Business is near symmetrical；

Transmission rate mean value (uplink and downlink is accumulative) is about 30-100 bytes-per-second；

About 50% packet is less than 100 bytes (such as confirmation packet due to agreement), remaining major part is less than 600 bytes；

Business is without periodical, in addition to message authentication and operation layer or the packet of transport layer protocol exchange correlation；

The mean value of arrival interval between data packet or between data packet group is probably 10 seconds magnitudes.

Compared with the above small data quantity business, average demand rate is big for large-data operation, and data packet is usually larger and connects It is continuous.

When reaching separately below for the business of different directions, specific UE access process is introduced.

Firstly, the case where when reaching for uplink service, referring to fig. 4, specific access process includes the following:

User equipment resides in one or more cells, it is assumed that the load of each adjacent area RAT can be got by broadcasting Information.

When multimode user equipment is when uplink service arrival needs to access network, user equipment, base station and CRRM can be by The accessible base station RAT is determined according to following steps joint:

S401: multimode user equipment is first simply according to the type of the multimode ability of user equipment, the uplink service of arrival The determination for can access with the information on load of each adjacent area RAT of acquisition the unification of RAT base station set needs can access later Initiate access request in the base station RAT in the unification of RAT base station set.For multimode multi-connection user equipment, RAT collection of base stations can access The base station RAT number in one can be greater than 1.And for multimode single connection user equipment, it can access the RAT in the unification of RAT base station set Base station number cannot be greater than 1.

When the type of the uplink service of arrival is voice service, then if in the RAT collection of base stations that user equipment is resident When in the presence of the base station RAT for supporting voice service, then user equipment supports voice services for all in resident RAT collection of base stations As can access the base station RAT, that is, can access the element in the unification of RAT base station set is to use for the base station RAT that load is most light in the base station RAT The most light base station RAT of the load in RAT collection of base stations that family equipment is resident.If user equipment is resident in RAT collection of base stations not When in the presence of the base station RAT for supporting voice service, then user equipment can select the support voice within the scope of user equipment multimode ability The base station RAT that load is most light in the base station RAT of business can access the member in the unification of RAT base station set as can access the base station RAT Element is the most light base station RAT of the load of the support voice service within the scope of user equipment multimode ability.

For example, it is assumed that user equipment supports LTE, 3G, GSM.If user equipment resides in 3G or GSM cell, Then user equipment directly initiates access request in the resident base station RAT.If user equipment resides in LTE cell, compare 3G net The load of network and GSM network directly initiates access request in the corresponding base station of the lighter network of load.

When uplink service is small data quantity business, then user equipment can choose within the scope of user equipment multimode ability For the most light network base station of load as can access the base station RAT, that is, can access the element in the unification of RAT base station set is that user equipment is more The most light base station RAT of load in mould limit of power.

When uplink service is large-data operation, user equipment preferentially can select user to set when selecting and can access RAT The base station RAT of the big quantity business of support within the scope of standby multimode ability, all base stations RAT for meeting this condition are known as candidate RAT Base station set unification.

If the network load that there is the candidate base station RAT in the unification of candidate's RAT base station set is no more than setting thresholding, meet this Condition is denoted as candidate RAT collection of base stations two, then the user equipment base station RAT that load in candidate RAT collection of base stations two is most light As the accessible base station RAT, that is, can access the element in the unification of RAT base station set is that load is most light in candidate RAT collection of base stations two The base station RAT.

If candidate RAT collection of base stations two is sky:

For multimode single connection user equipment, the most light base station RAT of the load in the unification of candidate RAT base station set is made To can access the base station RAT, that is, can access the element in the unification of RAT base station set is that load is most light in the unification of candidate's RAT base station set The base station RAT.

For multimode multi-connection user equipment, the support data service within the scope of user equipment multimode ability may be selected As can access the base station RAT, that is, can access the element in the unification of RAT base station set is that user equipment is more for preferable multiple base stations RAT The preferably multiple base stations RAT of support data service in mould limit of power.

Wherein, be described below about the support preferable base station RAT of data service: each RAT network can at the beginning of design There is the peak rate requirement of data service, so different RAT networks is also different for the support situation of data service.For example, For GSM network, initial network design is exactly in order to support voice service, so GSM network supports voice service preferable, still Data service supports bad that data service rate is lower (unit kbps)；So there is 3G network, the number that 3G network is supported It is higher (Mbps) according to service rate, and LTE network supports data service rate higher (hundred Mbps).So supporting data service A preferably important feature of RAT network itself.

For example, it is assumed that a multimode multi-connection user equipment supports LTE, 3G and GSM.If LTE cell base station is negative Lotus is not high, that is, is no more than assumed load thresholding, then user equipment can initiate access request in LTE base station.If LTE cell base Load of standing is more than assumed load thresholding, then user equipment can be in the preferable LTE of support data service, 3G network to the two Access request is initiated simultaneously in base station in network.

S402:, can be to this after the base station RAT in accessible RAT base station set unification receives the access request of user equipment Request carries out acceptance judging, and will include that the receiving result of the current assurable bit rate in the base station RAT is aggregated into CRRM section Point.

S403:CRRM node determines final receiving as a result, simultaneously adjusting final connect as needed according to following principle Enter the base station RAT, that is, determines accessible RAT collection of base stations two.Later, CRRM node can to the access request for receiving UE but be not can Access the RAT base station feedback access failure of element in RAT collection of base stations two；CRRM node is into accessible RAT collection of base stations two The RAT base station feedback for having been received by access request be successfully accessed.And CRRM node can select the base station RAT to require accessing The RAT base station information for not receiving access request that can access in RAT collection of base stations two is carried in response message.

Access request only is initiated on a certain base station RAT for user equipment in S401, then:

If received successfully on this base station RAT, CRRM node using this base station RAT as the final accessible base station RAT, The element that can access RAT collection of base stations two uniquely receives the access request of user equipment thus and receives the successful base station RAT.

If this base station RAT can only receiving portion business, CRRM node can select user equipment support the base station RAT according to Admission judgment is successively carried out according to load ascending order (i.e. load from small to large), the base station RAT if there is load lower than setting thresholding This business can be received completely, then CRRM node can access RAT base using this base station RAT as the final accessible base station RAT The element for set two of standing can receive the base station RAT of whole business thus.

The base station RAT if there is no load lower than setting thresholding can receive this business completely, then:

For multimode single connection user equipment, CRRM node the first RAT that the load for selecting user equipment to support is most light Base station receives one in the 2nd base station RAT of access request as the final accessible base station RAT.Specific selection Mode may is that if the first base station RAT and the 2nd RAT load of base station differ by more than pre-determined threshold, select user equipment branch The first most light base station RAT of the load held can access the element of RAT collection of base stations two as the final accessible base station RAT For the most light base station RAT of the load of user equipment support；If the difference of the first base station RAT and the 2nd RAT load of base station does not surpass Cross pre-determined threshold, then select the access request for receiving UE but can only receiving portion business the 2nd base station RAT as final Can access the base station RAT, that is, can access RAT collection of base stations two element be receive UE access request but can only receiving portion industry The base station RAT of business.

It should be noted that the value of the thresholding described in any in the embodiment of the present invention, can be decided according to the actual requirements, The embodiment of the present invention is not defined occurrence, and specific value size nor affects on the realization of the embodiment of the present invention.

For multimode multi-connection user equipment, CRRM node can be in the RAT base station range that user equipment is supported according to negative Lotus ascending order successively carries out the receiving of surplus lines, and by receive access request but can only receiving portion business the base station RAT and energy Success receives the base station RAT of surplus lines as the final accessible base station RAT, that is, can access the element of RAT collection of base stations two For receive access request but can only receiving portion business the base station RAT and can successfully receive the successful base station RAT of surplus lines.Its In, it is briefly exactly that the surplus resources of base station can guarantee remaining rate about the base station RAT for successfully receiving surplus lines (i.e. the request rate-of business receives the certifiable rate of the base station of access request, and obtained rate is remaining rate).

If failure is received in this base station RAT:

For multimode single connection user equipment, CRRM node excludes to have received access request in selection but receives failure The base station RAT.The most light base station RAT of load is as final in other base stations RAT that CRRM node can select user equipment to support The accessible base station RAT, that is, can access RAT collection of base stations two element be user equipment support the base station RAT in load it is most light The base station RAT.

For multimode multi-connection user equipment, the base station RAT that CRRM node can select user equipment to support is according to load liter Sequence successively carries out admission judgment, using can admission service a base station RAT or multiple base stations RAT as final accessible RAT Base station, that is, can access RAT collection of base stations two element be user equipment support can admission service a base station RAT or multiple The base station RAT.

Access request is initiated on multiple base stations RAT for user equipment in S401, illustrates that this user equipment is that multimode is more Connect user equipment, then:

If received successfully at least one base station RAT, CRRM node is using the most light base station RAT of wherein load as most The whole accessible base station RAT, that is, the element that can access RAT collection of base stations two be to feed back to receive successfully and the most light RAT base of load It stands.Not as the accessible base station RAT, CRRM node can be to these RAT base station feedback access failures for other base stations RAT.

If there is multiple base stations RAT can only receiving portion business, then CRRM node is according to the current guarantees of these base stations Rate, judges whether these base stations RAT can guarantee business demand, if these base stations RAT can guarantee business demand, by these As the final accessible base station RAT, that is, the element that can access RAT collection of base stations two is the multiple of the business that can guarantee for the base station RAT The base station RAT.If not being able to satisfy business demand, CRRM node will do it the receiving of surplus lines, and the access that will receive UE The base station RAT and the receiving successful base station RAT of surplus lines of request can access RAT base as the final accessible base station RAT Stand set two element be receive UE access request but can only receiving portion business the base station RAT and can successfully receive remaining industry It is engaged in the successful base station RAT.

If failure is received in this base station RAT, the base station RAT that CRRM node can select user equipment to support is according to load liter Sequence successively carries out admission judgment, using can admission service a base station RAT or multiple base stations RAT as final accessible RAT Base station, that is, can access RAT collection of base stations two element be user equipment support can admission service a base station RAT or multiple The base station RAT.

S404: the base station RAT for receiving CRRM node feeding back access failure can send access failure message to user equipment；And Message can be successfully accessed to user equipment transmission by receiving the base station RAT that CRRM node feeding back is successfully accessed, if on certain base station RAT The RAT base station information for not receiving access request in the accessible RAT collection of base stations two of CRRM node feeding back is also received, then this The RAT base station information that does not receive access request of the base station RAT in access response in the accessible RAT collection of base stations two of carrying, which is given, to be used Family equipment.

S405: the user equipment response to be accessed such as on the base station RAT for sending access request.If be successfully accessed, after The carrying Establishing process of continuous carry out business；If giving other accessible RAT base station informations, user equipment in access response Access request can be sent to the specified accessible base station RAT, carry out the carrying Establishing process of business again later.

When multimode user equipment is in Idle state and has downlink business arrival, referring to Fig. 5, can using following steps into The determination and acquisition of the accessible target RAT collection of base stations of row:

S501, network side (specific node for example can be CRRM node), can be according to before initiating paging to user equipment According to downlink business demand (such as transmission rate request), the multimode ability of user equipment and/or user equipment position area The information such as the load view of more base stations RAT determine that user equipment can access the base station target RAT.

Wherein, the load view of more base stations RAT in the user equipment position area, the i.e. position UE area be extremely The information on load of all base stations in the position area of few RAT a kind of.

When the downlink business of arrival is voice service, then if there is branch in the RAT collection of base stations that user equipment is resident When holding the base station RAT of voice service, then all support voice services in the RAT collection of base stations that user equipment is resident by network side The base station RAT that load is most light in the base station RAT is as the accessible base station target RAT.If the resident RAT collection of base stations of user equipment In there is no support voice service the base station RAT when, support voice service of the network side within the scope of user equipment multimode ability The base station RAT in select load most light network base station as the base station accessible target RAT.

As an example it is assumed that user equipment supports LTE, 3G and GSM, when the downlink business of arrival is voice service, such as Fruit user equipment resides in 3G or GSM cell, then the base station RAT that user equipment is resident by network side is as accessible target The base station RAT.If user equipment resides in LTE cell, compare the load of 3G and GSM network, determines the lighter RAT base of load It stands to can access the base station target RAT.

It is small data quantity business when downlink reaches business, then network side can choose within the scope of user equipment multimode ability Base station in the most light network of load is as the accessible base station target RAT.

When it is large-data operation that downlink, which reaches business, then network side can be according to user equipment multimode ability and user The load view in equipment position area can access the selection of the base station target RAT.

It, can be more according to user equipment if network side can know user equipment persistent district information or location information The load of each base station RAT in mould ability and user equipment position area can access the determination of the base station target RAT.For Multimode single connection user equipment, the load that can choose the support big data business within the scope of user equipment multimode ability are most light The base station RAT is as the accessible base station target RAT.For multimode multi-connection user equipment, if there is support big data business and Load is lower than the base station RAT of pre-determined threshold, then can choose this base station RAT as the accessible base station target RAT.It otherwise, can be with Select the support big data business preferably one or more base station RAT within the scope of user equipment multimode ability as accessible mesh Mark the base station RAT.

If network side only knows the position area where user equipment, in this case it is not apparent that user equipment is specific in the area of position Position can then carry out can access target according to the load view of user equipment multimode ability and user equipment position area The selection of the base station RAT.CRRM node calculates each RAT base in the area of user equipment position within the scope of user equipment multimode ability The average load or overloaded cells ratio of each cell in user equipment position area are in standing.If there is the big number of support Each cell average load or overloaded cells ratio of the network of amount business in user equipment position area are no more than setting thresholding, Then using the base station in the most light network of load as the base station accessible target RAT.Otherwise, for multimode single connection user equipment, Network side can be by the average negative of the base station in preferably each cell of support data service within the scope of user equipment multimode ability The minimum base station RAT of the ratio of base station in lotus or overloaded cells is as the accessible base station target RAT.Multimode multi-connection is used Family equipment can choose and support the preferably multiple base stations RAT of data service within the scope of user equipment multimode ability are used as can Access the base station target RAT.

As an example it is assumed that the RAT that multimode multi-connection user equipment is supported includes LTE, 3G and GSM.If small in LTE In area, each cell average load or overloaded cells ratio in location of user equipment area be not high, then by the base station in LTE cell As the base station target RAT.If each cell average load or overloaded cells in LTE cell, in location of user equipment area Ratio is higher than pre-determined threshold, then the target for being used as user equipment to access the base station in the base station and 3G cell in LTE cell The base station RAT.

It should be noted that the selected heavier probability of RAT load of base station can be reduced using the method.But There are the heavier possibility of target RAT load of base station of selection.If the target RAT load of base station of selection is heavier, user equipment After the access of the base station target RAT of selection, CRRM node will do it adjustment, and situation is such as CRRM node when uplink service reaches Operation, i.e. the network side base station target RAT that access is determined based on business demand and base station information factor.

S502, network side issue the paging message to this user equipment.If the resident base station RAT of user equipment and step The base station accessible target RAT determined in S501 is inconsistent, then carrying in paging message can access target RAT base station information, User equipment can be allowed directly to access in the accessible base station target RAT, in this way to reduce business setup delay.If user equipment The resident base station RAT is consistent with the base station accessible target RAT, then the target RAT base for carrying access is not needed in paging message It stands information, to reduce signaling traffic load.

Wherein, the information of the resident base station RAT of user equipment, network side can be known using the prior art.

After S503, user equipment receive paging message, if carrying the base station accessible target RAT letter in paging message Breath, then user equipment directly can initiate access request to the base station accessible target RAT, carry out page response.If paging message In do not carry the base station accessible target RAT, then user equipment can to the resident base station RAT initiate access request, carry out paging sound It answers.
