Description

Management method and device for mobile broadband data transmission

Technical Field

The present invention relates to the field of mobile communications, and in particular, to a method and a system for implementing mobile broadband data transmission by using multiple WLAN Access Points (APs) in a cellular mobile system in a 3GPP (3rd Generation Partnership project) family system.

Background

Cellular mobile systems within the 3GPP (3rd Generation Partnership project) family of systems may include a cross-system cooperation interworking mode between a Long Term Evolution system LTE (Long Term Evolution, including a Network side NW and a terminal side UE) and its subsequent next Generation cellular systems, and a Wireless Local Access Network WLAN (including a Network side and a terminal side) and its subsequent next Generation systems, such as an HEW (High efficiency Wireless Local area Network).

With the increasing number of signed users of mobile communication operators and the increasing amount of mobile services such as user voice data, the mobile communication operators will grow exponentially in the future, and the investment and deployment scale of the infrastructure of the mobile communication network must be correspondingly increased, so that the breadth and depth of wireless coverage and the system communication capacity can both meet the increasing objective requirements of users. Taking european majority of Mobile communication operators as an example, they have historically deployed 3 Mobile communication systems of different RAT (Radio Access Technology ) formats (all of which are formats within the 3GPP communication System family), GSM (Global System of Mobile communication), UMTS (Universal Mobile Telecommunications System ), and LTE, which all operate on licensed carriers within the licensed spectrum. In order to further enhance the functions of the mobile communication network and expand the system capacity, mobile communication operators also widely and abundantly deploy such as WLAN systems within the IEEE communication system family (evolving towards the next generation HEW system) as an efficient and low-cost wireless capacity supplement. Although a 3 GPP-like cellular mobile network cannot be independently constructed with high performance, WLAN systems are very powerful market-life and competitive because they are technically simpler and much less expensive to physically implement than 3GPP systems and operate on unlicensed carriers within a free and much wider unlicensed spectrum.

Since the multiple wireless communication systems (Multi-RAT) are deployed in a long-term evolution coexistence manner and provide wireless access and data transmission services together, in order to enhance the inter-system mobility, enhance the KPI experience of the mobile communication of the user, save the development and maintenance cost of software and hardware, and facilitate the operation and maintenance management of the "Multi-RAT large network" by operators, 3GPP has developed and formulated multiple versions of standardized technologies to couple the various wireless communication systems together in different degrees/levels to form a so-called cross-system joint interoperation. As shown in one example of a network architecture in fig. 1: WLAN AP and 3GPP 3 main wireless access network units are connected to the same converged core network CN together, operators can flexibly and cooperatively transmit information such as capability/configuration/state between different RATs, reasonable movement strategies are formulated, and UE is served under the most appropriate RAT base station/cell according to the service QOS characteristics and the requirement of resource state. The benefits of enhancing joint interoperation between different RATs are: different RATs can better exert the advantages and the characteristics of respective systems, wireless communication loads of a large number of users can be shared flexibly and evenly among the different RATs, hardware resources can be formed among the different RATs, wireless coverage and capacity are dynamically complemented, and therefore a high-performance KPI is brought to the whole 'Multi-RAT large network', and better mobile communication experience and feeling are brought to the large number of users.

According to the prior art, a terminal with WLAN/3GPP multimode capability can be in communication connection/data transmission state with an AP or an access node of a WLAN future evolution or revolution system and a base station of a certain RAT in 3GPP family at the same time. Taking the joint interoperation between WLAN and LTE systems as an example (the idea principle is basically applicable to the joint interoperation between other RATs), for example, a terminal with a certain WLAN/LTE dual-mode capability is simultaneously under the coverage of a wireless signal of a WLAN/LTE cell, the terminal establishes an RRC (Radio Resource Control) connection with an LTE network at a certain time, then performs bidirectional data transmission of a certain IP service flow a, and then the user initiates a new IP service flow B. Under the User manual control, UP (User Preference), the terminal searches for a coverage signal of the WLAN and completes the necessary AP network entry association authentication registration (this process is referred to as WLAN network selection registration), and then the converged CN may migrate the IP traffic B to the WLAN system that the terminal has successfully registered before according to certain policy rules and upper layer protocol signaling, and thereafter the IP traffic a of the terminal is still carried in the LTE network, and the IP traffic B is carried in the WLAN network (this process is referred to as WLAN data offloading), which is illustrated in fig. 2 a/2B.

By 3GPP Rel-13 release, there have been many basic mechanisms for coupling joint interoperability for WLAN-LTE, in addition to the above-exemplified manual configuration UP, (e) ANDSF (Enhanced Access Network Discovery Selection Function), (e) ITW (Enhanced RAN Rule Based Interworking mechanism), LWA (LTE WLAN Aggregation, Aggregation between LTE and WLAN systems), and the like. In addition to the LWA mechanism, the above mechanisms all need to rely on the UE to release the IP Flow/DRB (Data Radio Bearer ) Radio Bearer originally in the LTE network, and establish/maintain the WLAN connection through the WLAN air interface signaling and the target AP, so as to implement the migration and offloading of the IP Flows carrying the user service Data on the core network side; the LWA mechanism as a tight coupling mode does not cause the migration of IP Flows on the core network side, only user plane partial data of the IP Flow/DRB radio bearer in the LTE network is transmitted through the target APs tightly coupled to each other, and the anchor point MeNB on the radio access side controls the addition/reconfiguration/deletion of the target AP and the forwarding and recovery of related split data, which can be understood as: the MeNB (master base station node) is a centralized control node for all APs in the LWA mode of operation.

In the past, 3GPP has extensively discussed the above mechanisms, all of them are based on a UE with "single AP connection capability", that is, a specific UE can only perform association authentication with one target AP at most at a certain time, and can only perform data transmission through one WLAN air interface link. Such "single AP connection capability" UE is usually configured with only one set of WLAN-related rf baseband resources internally, and the physical limitation of this UE capability configuration has the following disadvantages:

if the 3GPP system-related resources deployed on the network side of the operator are less (for example, the deployed LTE authorized carriers are less and narrow, and the 3GPP system-related BU processing resources are less), and the WLAN system-related resources deployed on the network side are more (for example, the deployed WLAN unlicensed carriers are more and wide, and the WLAN system-related BU processing resources are more), for the "single AP connection capability" UE, imbalance Mismatch occurs necessarily in the ratio of the capability configuration on the network side, so that part of the 3 GPP-related capability resources in the UE is idle, and the UE only has one set of WLAN resource module, but cannot fully utilize the WLAN resources on the network side.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

Fig. 3 is a flowchart of a management method for mobile broadband data transmission according to the present invention. The method shown in fig. 3 comprises:

301, acquiring capability information of at least two sets of WLAN resource function modules in the terminal;

step 302, according to the capability information, configuring the at least two sets of WLAN resource function modules one by one to perform association authentication with corresponding AP or access nodes of a WLAN future evolution or revolution system;

in the LTE system, the AP or the access node of the WLAN future evolution or revolution system is an AP, and certainly, the AP or the access node of the WLAN future evolution or revolution system in the LTE future evolution system is a node having a function of an AP in LTE;

correspondingly, when the system is a WLAN future evolution or revolution system, the WLAN resource module is also suitable for having a function matched with the system;

and 303, managing the terminal to transmit the mobile broadband data by using the at least two sets of WLAN resource function modules and the corresponding AP or the access node of the WLAN future evolution or revolution system.

Wherein "managing" specifically means: the basic actions of independent establishment, configuration, reconfiguration, maintenance, deletion and the like of each WLAN link are consistent with the basic operation of the existing single WLAN link.

The method provided by the invention utilizes at least two sets of WLAN resource function modules in the terminal to respectively establish connection with the access node for each WLAN resource function module, realizes that the terminal and the network side have a plurality of transmission links, improves the data transmission efficiency, and fully utilizes the resources of the network side.

The method provided by the present invention is further described below:

Specifically, by acquiring the capability information of the WLAN resource function module, a suitable AP or an access node of a WLAN future evolution or revolution system may be selected for the WLAN resource module according to the capability information, so as to ensure the stability of the established connection.

In addition, the configuring, according to the capability information, the at least two sets of WLAN resource function modules one by one to perform association authentication with corresponding APs or access nodes of a WLAN future evolution or revolution system includes:

acquiring a WLAN resource function module in an idle state in the terminal;

and configuring the WLAN resource function module in the idle state.

Specifically, in the process of configuring WLAN resource function modules one by one, there may be a problem that some modules are in a working state, and if the modules in the working state are configured, data being transmitted by the modules may be affected, so that data transmission is interrupted.

Specifically, the links obtained by the APs or the access nodes of the WLAN future evolution or revolution system connected to each set of WLAN resource function modules correspond to the multiple WLAN working links established between the UE and the network side AP or the access nodes of the WLAN future evolution or revolution system, and in the established time sequence, if the conditions are satisfied, the links can be established simultaneously, that is, only the difference of the order in logic is processed, and there is no great difference of the order in time.

Because different links logically and independently exist between the AP on the network side or the access node of the WLAN future evolution or revolution system and the plurality of sets of WLAN functional modules in the UE, the different links can work independently, the working state change of any WLAN link cannot influence the working states of other WLAN links, and is only influenced by the control and state conditions of policy criteria parameters and the like configured for each WLAN link on the 3GPP network side.

controlling a main WLAN link in the terminal to shunt load or reversely offload to load mobile broadband data in the UE;

controlling the nth auxiliary WLAN link in the terminal to shunt load or reversely offload to load the mobile broadband data in the UE; the IP Flows carried by the nth auxiliary WLAN link are from the mobile broadband data left by the UE on the 3GPP network side; or, the mobile broadband data carried by the primary WLAN link and the 1st to the n-1 st secondary WLAN links are already shunted; and n is less than m-1, wherein n and m are positive integers, and m is the total number of the WLAN resource function modules in the terminal.

For ease of understanding, the following description is given in a specific flow scheme:

the following description takes the system as LTE as an example:

s1, in the capability range of some WLAN resource function module in UE, 3GPP network side makes some AP1 node deployed in network side and the WLAN resource function module in UE form association connection according to the existing technology mode based on some non-LWA mechanism supported by it, completes the necessary WLAN access authentication registration and other processes, at this time UE is established to obtain main WLAN link PWL (Primary WLAN Link). After successful establishment, the 3GPP network side allows the AP1 and the UE to perform related uplink and downlink data transmission over the air interface based on the existing technology of the set of non-LWA mechanisms, that is, according to policy criteria parameters and the like specified by the non-LWA mechanisms, the PWL is used to offload bearers or reverse offload to offload part of IP Flows in the UE.

S2: after S1, if some WLAN resource function module in the UE is in an idle and unused state, in the capability range of the set of WLAN resource function module, based on some non-LWA mechanism that can be supported by the 3GPP network side, under a certain condition, according to the prior art, a certain AP2 node deployed on the network side forms an association connection with the set of WLAN resource function module in the UE, and completes necessary WLAN access authentication registration and the like, at this time, the UE is established to obtain a first Secondary WLAN Link SWL (1st Secondary WLAN Link). After successful establishment, the 3GPP network side allows the AP2 and the UE to perform related uplink and downlink data transmission over the air interface based on the existing technology of the set of non-LWA mechanisms, that is, according to policy criteria parameters and the like specified by the non-LWA mechanisms, the 1st SWL is used to offload bearers or reverse offload to offload part of IP Flows in the UE. The IP Flows of the 1st SWL bearer may be from the user data Flows left by the UE on the 3GPP network side, or may be the user data Flows of the PWL already offloaded bearers.

S3: similar to the principle mode of S2 processing, the 3GPP network side continues to detect the unused WLAN resource function module inside the UE, and based on some non-LWA mechanism that it can support, under certain conditions, according to the prior art, tries to make other APx nodes deployed on the network side and the set of WLAN resource function module in the UE form an association connection, and completes necessary WLAN network entry authentication registration and other processes, at this time, the UE is established to obtain more second/third/fourth equal Secondary WLAN links SWL (2nd/3rd/4th … Secondary WLAN Link). After successful establishment, the 3GPP network side allows APx and UE to perform related uplink and downlink data transmission over the air interface based on the existing technology of the set of non-LWA mechanisms, that is, according to policy criteria parameters and the like specified by the non-LWA mechanisms, more 2nd/3rd/4th … SWL are used to offload bearers or reverse offload to offload part of IP Flows in the UE. The IP Flows carried by the 2nd/3rd/4th … SWL may be from the user data Flows left by the UE on the 3GPP network side, or may be the user data Flows carried by the previous PWL and 1st SWL shunted, and then are successively recurred.

Note that PWL and 1st,2^nd,3^rd,4^th… SWLs can be established based on the policy criteria parameters and the like corresponding to the same non-LWA mechanism (corresponding to the same set of policy criteria parameters and the like configured for all target APs on the 3GPP network side), and under the same state condition, in this case, PWLs and 1st,2 st are used^nd,3^rd,4^th… the SWL is different from the others in name and convenience for description, and has no essential difference (can be called as PWL); PWL and 1st,2^nd,3^rd,4^th… SWL may be established based on policy criteria parameters corresponding to different non-LWA mechanisms (corresponding to different policy criteria parameters configured for different target APs by the 3GPP network side), or under different state conditions, in which case PWL and 1st,2 st^nd,3^rd,4^th… SWLs have multiple differences in their shunting capabilities and setup/maintenance/release, and therefore need to be more strictly differentiated。

In addition, when the following conditions are detected, the operation of configuring the at least two sets of WLAN resource function modules and performing association authentication with the corresponding access node AP or the access node of the WLAN future evolution or revolution system is stopped, including:

The method for judging whether an access node of LTE or LTE future evolution or revolution matched with the capability information of the WLAN resource function module exists or not comprises the following steps:

determining the capability information of an access node of an AP or WLAN future evolution or revolution system matched with the capability information of a WLAN resource function module in the terminal according to the capability information of the terminal, wherein the capability information of the access node of the AP or WLAN future evolution or revolution system comprises at least one of signal coverage strength, wireless load, backhaul bandwidth, WLAN authentication information and WLAN registration information of the access node of the AP or WLAN future evolution or revolution system;

and searching the AP or the access node of the WLAN future evolution or revolution system with the capability information of the AP or the access node of the WLAN future evolution or revolution system according to the capability information of the AP or the access node of the WLAN future evolution or revolution system.

Of course, after stopping configuring the at least two sets of WLAN resource function modules with the AP or the access node of the WLAN future evolution or revolution system for performing the association authentication, the method further includes:

Therefore, when the resource capacity does not accord with the establishment of the multi-AP connection, the establishment process is stopped in time, the process of establishing the multi-AP connection can be managed through the management of the capacity information of the UE and the network side resource so as to ensure that the multi-AP connection is established in time, the multi-WLAN APs resource on the network side and the multi-set WLAN function module resource in the UE are utilized as much as possible, and the utilization rate of the resource is improved.

The above process is illustrated below in two examples:

example 1: as shown in fig. 4, an operator deploys an LTE macro cell network to provide basic wireless coverage for users, and in order to enhance network capacity, the operator further deploys WLAN APs with a bandwidth of 40M on some unlicensed carrier frequency points in unlicensed 2.4G and 5G frequency bands, respectively, to offload IP Flows carrying user services. A terminal UE 1 is resident in an LTE macro cell and maintains RRC connection with an eNB base station, while the UE 1 is under coverage of multiple WLAN APs radio signals.

S100: the internal hardware of the UE 1 is provided with: 1 set of WLAN radio frequency baseband function module A (WLAN module A for short) capable of supporting 2.4G frequency band 40M bandwidth and 1 set of WLAN radio frequency baseband function module B (WLAN module B for short) capable of supporting 5G frequency band 40M bandwidth are reported to eNB through LTE air interface RRC information, so that the LTE network side learns the related capability that UE 1 can support multi-AP connection. Furthermore both WLAN modules of UE 1 support the ITW joint interworking mechanism.

S101: the eNB configures strategy criterion parameters related to ITW for a WLAN module A of the UE 1 through RRC private signaling, under a specific WLAN condition, according to the existing ITW technical mode, an AP1 node on a 2.4G frequency band and the WLAN module A in the UE 1 form association connection firstly, necessary processes such as WLAN access authentication registration are completed, and at the moment, the UE 1 is established to obtain a main WLAN link PWL. After successful establishment, some IP Flows originally carried within the LTE macrocell are tapped off by the PWL.

S102: the eNB further configures strategy criterion parameters related to ITW for the WLAN module B of the UE 1 through RRC private signaling, under a specific WLAN condition, according to the existing ITW technical mode, a certain AP2 node on a 5G frequency band and the WLAN module B in the UE 1 can also form associated connection, necessary WLAN access authentication registration and other processes are completed, and at the moment, the UE 1 is established to obtain an auxiliary WLAN link SWL. After successful establishment, some IP Flows originally carried in the LTE macro cell can be dropped by the SWL.

Note: because the WLAN system is based on the working mode of the unlicensed radio resource contention based lbt (list Before talk) at the air interface, the two sets of WLAN modules in the UE 1 cannot perform the operation like LTE carrier aggregation on the vertical plane of the frequency spectrum (the WLAN modules cannot align the transmission time of multiple data blocks). The UE 1 simultaneously performs WLAN data distribution with the two target APs, so that the distribution capability of the LTE macro network to the WLAN network can be further enhanced, and the data throughput rate of a user is improved.

S103: since UE 1 has only two sets of WLAN modules and both are already utilized, no more SWL can be established.

S104: although the eNB temporarily detects that all WLAN modules inside the UE 1 are already used, as the UE moves in location and the WLAN conditions change (such as signal coverage strength quality and radio load), it needs to perform polling detection to make "dual AP connection" more updated, and use as much WLAN APs resources on the network side and two sets of WLAN modules inside the UE as possible. The target AP nodes of UE 1 in the 2.4G and 5G bands will be updated and changed independently, and the specific situation of the shunted IP Flows continues to be performed according to the policy criteria parameters related to the ITW configured by the eNB respectively.

Example 2: as shown in fig. 5, an operator deploys an LTE macro cell network to provide basic wireless coverage for users, and in order to enhance network capacity, the operator further deploys WLAN APs with a bandwidth of 80M continuously and adjacently on a certain unlicensed carrier frequency point of unlicensed 2.4G, so as to offload IP Flows carrying user traffic. A terminal UE 2 is resident in the LTE macrocell and maintains RRC connection with the eNB base station, while the UE 2 is under overlapping coverage of two adjacent WLAN APs radio signals.

S200: the UE 2 internal hardware is equipped with: 2 sets of WLAN radio frequency baseband function modules (WLAN module A/B for short) capable of supporting 2.4G frequency band 80M bandwidth and 1 set of WLAN radio frequency baseband function module C (WLAN module C for short) capable of supporting 5G frequency band 80M bandwidth are reported to eNB through LTE air interface RRC information, so that the LTE network side learns the related capability that UE 2 can support multi-AP connection. Furthermore, the 3 WLAN modules of UE 2 all support the ean dsf joint interworking mechanism.

S201: the eNB configures strategy criterion parameters related to eANDSF for a WLAN module A/B of the UE 2 through RRC private signaling, under a specific WLAN condition, according to the existing eANDSF technical mode, a certain AP1 node on a 2.4G frequency band and the WLAN module A in the UE 2 form association connection firstly, necessary WLAN access authentication registration and other processes are completed, and at the moment, the UE 2 is established to obtain a main WLAN link PWL. After successful establishment, some IP Flows originally carried within the LTE macrocell are tapped off by the PWL.

S202: further, under a specific WLAN condition, according to the existing ean sf technical manner, the AP2 node adjacent to the AP1 node on the 2.4G frequency band also forms an association connection with the WLAN module B in the UE 2, and completes necessary WLAN network entry authentication registration and other processes, and at this time, the UE 2 is established to obtain an auxiliary WLAN link SWL. After successful establishment, some IP Flows originally carried in the LTE macrocell and on the PWL can be dropped by the SWL.

Note: because the WLAN system is based on the working mode of the lbt (listen Before talk) of the unlicensed wireless resource contention at the air interface, the AP1 and the AP2 on the same WLAN unlicensed working frequency point may not necessarily send the data block to the UE 2 at the same time, and who successfully preempts the local channel resource first may send the data block. The network side may also choose to let the neighboring AP1 and AP2 carry the same IP Flow, thereby forming transmit/receive diversity gain.

S203: although UE 2 has 1 set of idle WLAN module C, since the network side does not provide WLAN AP node resources in the 5G band, it cannot establish more SWL.

S204: although the eNB temporarily detects that all WLAN modules inside the UE 2 are utilized as much as possible, as the UE moves in location and the WLAN self condition changes (such as signal coverage strength quality, radio load, entering into the coverage of the WLAN AP node in the 5G band), it needs to perform polling detection to make "multi-AP connection" more updated, and use as much as possible of the network-side WLAN APs resources and 3 sets of WLAN modules inside the UE. The target AP node of UE 2 in the 2.4G or 5G frequency band is updated and changed independently, and the specific situation of the shunted IP Flows is continued according to the policy criteria parameters related to the ean dsf respectively configured by the eNB.
