Description:
[0001]    This application claims the priority to Chinese Patent Application No. 201310337395.X, filed with the State intellectual Property Office of People&#39;s Republic of China on Aug. 5, 2013 and entitled “Method and device for configuring a bearer”, the content of which is hereby incorporated by reference in its entirety. 
       FIELD 
       [0002]    The present invention relates to the field of wireless communications and particularly to a method and device for configuring a bearer. 
       BACKGROUND 
       [0003]    In order to facilitate deployment of a new service, the Long Term Evolution (LTE) system is designed with separation of the user plane from the control plane so that control plane signaling and a user plane bearer are dominated respectively by separate network elements, which are a Mobile Management Entity (MME) and a Serving Gateway (SGW). The MME primarily functions for Non-Access Stratum (NAS) signaling setup, NAS signaling security, signaling setup across a core network, service tracking (for a UE in an idle mode), a roaming service, authorization and bearer management, etc. The SGW functions as a gateway for Evolved NodeB (eNB) switching, a gateway for forwarding 2G/3G and other system services, for buffering downlink packets, for some initializing operations, specified interception and detection, packet routing and forwarding, etc. A Packet Data Gateway (PDN GW or PGW) functions for policy enforcement, packet filtering, specified interception, allocation of User Equipment Internet Protocol (UEIP) addresses, charging, packet reproduction, etc. 
         [0004]    A fast path or connectionless transmission solution to the core network is proposed, where in an attachment or Tracking Area Update (TAU) procedure of the user equipment, the MME selects some bearer, and allocates an SGW bearer index ID, i.e., a resource identifier, for the user equipment so that there is one-to-one mapping between the resource identifier, an SGW S1 user plane interface (S1-U) Tunnel End Point Identifier (TEID), and an address, and the UE and the eNB can be provided with the SGW S1-U TEID and the IP address, The SGW S1-U TEM is a Tunnel End Point Identifier (TEM) of the SGW determined by the network in the General Packet Radio Service (GPRS) Tunneling Protocol for User Plane (GTP-U) while setting up the S1-U bearer of the eNB for the UE. The user equipment stores the identifier. 
         [0005]    For data transmission triggered by arriving uplink data, if both the network and the user equipment support this transmission solution, then the user equipment may decide whether to enable transmission in this solution. The user equipment transmits uplink data by carrying the resource identifier in the data. The eNB decodes the data, obtains address information of the SGW according to the resource identifier, and forwards a GTP-U data packet including the information to the corresponding SGW, where the data packet also includes the eNB SI1-U TEED allocated by the eNB. 
         [0006]    For data transmission triggered by arriving downlink data, if the SGW finds that no bearer is activated (there is no corresponding eNB S1-U TEID), then the SGW may page the user equipment through the MME, and the user equipment may initiate a Radio Resource Control (RRC) connection to activate the bearer. 
         [0007]    Each UE can be provided with a plurality of different resource identifiers corresponding to different QoS configurations. 
         [0008]    At present an advantage of this solution is that a signaling procedure of setting up the control plane between the eNB and the MME, and a signaling procedure of setting up the user plane between other Central Nodes (CNs) are omitted. 
         [0009]    However in the existing fast path or connectionless transmission solution, each UE may be provided with a plurality of resource identifiers, each of which may correspond to different resource parameter configurations The eNB setting up for the UE a bearer corresponding to some resource identifier cannot configure the UE with the bearer due to no knowledge of the resource parameter configuration corresponding to the resource identifier.

         [0132]    In the operation  202 , the user equipment transmits the resource parameter configuration identifier to a network-side device so that the network-side device determines resource parameter configuration information corresponding to the received resource parameter configuration identifier according to a first correspondence relationship between the resource parameter configuration identifier and the resource parameter configuration information, and configures the user equipment with the bearer according to the determined resource parameter configuration information. 
         [0133]    Alternatively the resource parameter configuration identifier is a specific resource identifier, or a resource parameter configuration indicator. 
         [0134]    If the resource parameter configuration identifier is the resource parameter configuration indicator, then: 
         [0135]    Before the user equipment determines the resource parameter configuration identifier corresponding to the bearer, the method further includes: 
         [0136]    If the network-side device configures the user equipment with the specific resource identifier, then the user equipment receives the resource parameter configuration indicator from the network-side device, and creates a second correspondence relationship between the resource parameter configuration indicator and the specific resource identifier, and 
         [0137]    The user equipment determines the resource parameter configuration identifier corresponding to the bearer as follows: 
         [0138]    The user equipment determines the resource parameter configuration indicator corresponding to the specific resource identifier of the bearer according to the second correspondence relationship. 
         [0139]    In a particular implementation, the user equipment according to the embodiment of the invention can be a handset, a tablet computer, a notebook computer, a data card, a netbook computer, a smart watch, a wireless wideband hotspot router (MiFi), and products, including a digital camera, a smart electric meter, a home appliance, etc., capable of wireless communication. The user equipment can communicate wirelessly with different base stations using one or several wireless access technologies. 
         [0140]    The solution according to the invention will be described in connection with several different scenarios listed below 
         [0141]    In a first example, an initial configuration need to be made prior to an MO process according to the embodiment of the invention: 
         [0142]    1. The eNB obtains through the OAM device a QoS configuration for transmission of an IP packet; or 
         [0143]    2. When allocating a resource identifier to the UE, the MME transmits a QoS identifier (i.e., a resource parameter configuration identifier and a QoS configuration corresponding to the resource identifier to the eNB; and when allocating the resource identifier to the UE side, the eNB notifies the QE of the QoS identifier and the QoS configuration corresponding to the resource identifier. 
         [0144]    Referring to  FIG. 3 , an MO activating bearer process includes the following operations: 
         [0145]    In the operation  301 , the UE transmits a Random Access Preamble to the eNB. 
         [0146]    In the operation  302 , the eNB returns a Random Access Response message to the UE. 
         [0147]    In the operation  303 , the UE transmits an RRC Connection Request message to the eNB. 
         [0148]    In the operation  304 , the eNB returns an RRC Connection Setup message to the UE. 
         [0149]    The operation  301  to the operation  304  relates to the random access procedure initiated if the UE has an uplink IP packet to be transmitted. 
         [0150]    In the operation  305 , after an RRC connection is set up, the UE transmits a Connection Setup Complete message to the eNB, and transmits a resource identifier of the core network side of the UE and a QoS identifier (the QoS identifier here is a resource parameter configuration identifier) to the eNB in the Connection Setup Complete message, according to a bearer of the core network side for the uplink IP packet to be transmitted by the UE. 
         [0151]    In the operation  306 , the eNB determines the SGW to which the IP packet is transmitted by the UE, according to the resource identifier of the core network side of the UE, configures a specific DRB with a QoS configuration corresponding to the QoS identifier, creates a correspondence relationship between the DRB and the bearer of the core network side, and transmits an RRC Connection Reconfiguration message including the resource identifier and a DRB identifier to the UE. 
         [0152]    The DRB identifier here identifies the bearer of the access network, and the resource identifier identities the bearer of the core network. 
         [0153]    The eNB can create a correspondence relationship between the resource identifier and the DRB so that the UE transmitting the uplink data can simply transmit the data over the corresponding DRB without transmitting the resource identifier (which is only used for addressing by the eNB to locate the corresponding SGW) each time the UE transmits data, thus the eNB can know that the data received over the DRB shall be forwarded to the corresponding SGW. 
         [0154]    In the operation  307 , the UE transmits an RRC Connection Reconfiguration Complete message to the eNB. 
         [0155]    In the operation  308 , the UE transmits the IP packet to the eNB over the activated bearer with the specific QoS. 
         [0156]    In the operation  309 , the eNB transmits the IP packet to the SGW over the activated bearer with the specific QoS. 
         [0157]    In the operation  310 , the SGW returns a response message corresponding to the IP packet to the eNB over the activated bearer with the specific QoS. 
         [0158]    In the operation  311 , the eNB returns the response message corresponding to the IP packet to the UE over the activated bearer with the specific QoS. 
         [0159]    In the operation  307  to the operation  311 , the UE sets up the DRB, and the eNB schedules transmission of the specific IP packet of the UE over the DRB according to the corresponding QoS configuration. 
         [0160]    In the operation  312 , all of the UE, the eNB, and the SGW start a timer (Timeout of Fast Path) each time the IP packet is transmitted, where the bearer is active before the timer expires, and if the timer expires, then the corresponding bearer will be deactivated. The eNB can transmit an RRC Connection Release message to the UE to release the RRC connection of the UE. 
         [0161]    If a PDN connection is set up in advance between the UE and the core network side, then a correspondence relationship between the bearer and the QoS can be created using a Connection ID and the QoS identifier and the QoS identifier can also be sent in the RRC Connection Setup Request message, and the DRB configuration for the UE can be transmitted in the RRC Connection Setup message. Other parameters than the QoS can also be configured similarly, so a repeated description thereof will be omitted here. 
         [0162]    In a second example, an initial configuration need to be made prior to an MT process according to the embodiment of the invention: 
         [0163]    1. The eNB obtains through the OAM device a QoS configuration for transmission of a IP packet; or 
         [0164]    2. When allocating a resource identifier to the UE, the MME transmits a QoS identifier (i.e., a resource parameter configuration identifier) and a QoS configuration corresponding to the resource identifier to the eNB; and when allocating the resource identifier to the UE side, the eNB notifies the UE of the QoS identifier and the QoS configuration corresponding to the resource identifier. 
         [0165]    Referring to  FIG. 4 , an MT activating bearer process includes the following operations: 
         [0166]    In the operation  401 , the SGW receives a downlink IP packet for the UE, from the PGW. 
         [0167]    In the operation  402 , the SGW transmits a Downlink Data Indicator (DDN) message including a resource identifier of a bearer to the MME for the MME to call the UE. 
         [0168]    In the operation  403 , the MME transmits a paging message including the resource identifier of the bearer to the eNB. 
         [0169]    In the operation  404 , the eNB transmits a paging message including the resource identifier of the bearer to the eNB. 
         [0170]    In the operation  405 , the UE transmits a Random Access Preamble to e eNB. 
         [0171]    In the operation  406 , the eNB returns a Random Access Response message to the UE. 
         [0172]    In the operation  407 , the eNB returns an RRC Connection Setup message to the UE. 
         [0173]    In the operation  408 , the eNB returns an RRC Connection Setup message to the UE. 
         [0174]    in the operation  405  to the operation  408 , the random access procedure is initiated by the UE receiving paging of the IP packet. 
         [0175]    In the operation  409 , after an RRC connection is set up, the UE transmits a Connection Setup Complete message to the eNB, and transmits a resource identifier of the core network side of the UE and a QoS identifier (the QoS identifier here is a resource parameter configuration identifier) to the eNB in the Connection Setup Complete message, according to a bearer of the core network side for the uplink IP packet to be transmitted by the UE. 
         [0176]    In the operation  410 , the eNB determines the SGW to which the IP packet is transmitted by the UE, according to the resource identifier of the core network side of the UE, configures a specific Data Radio Bearer (DRB) with a QoS configuration corresponding to the QoS identifier, creates a correspondence relationship between the DRB and the bearer of the core network side, and transmits an RRC Connection Reconfiguration message including the resource identifier and a DRB identifier to the UE. 
         [0177]    In the operation  411 , the UE transmits an RRC Connection Reconfiguration Complete message to the eNB. 
         [0178]    In the operation  412 , the UE transmits a dummy IP packet to the eNB, 
         [0179]    In the operation  413 , the eNB transmits a dummy IP packet to the SGW to activate transmission of the downlink IP packet. 
         [0180]    Here a dummy IP packet can alternatively be transmitted directly by the eNB instead of the UE to the SGW. 
         [0181]    In the operation  414 , the SGW activates the bearer, and transmits a Downlink Data Indicator (DDN) Complete message to the MME, upon reception of the dummy IP packet 
         [0182]    In the operation  415 , the SGW transmits the IP packet to the eNB over the activated bearer with the specific QoS. 
         [0183]    In the operation  416 , the eNB transmits the IP packet to the UE over the activated bearer with the specific QoS. 
         [0184]    In the operation  417 , the UE returns a response message corresponding to the IP packet to the eNB over the activated bearer with the specific QoS. 
         [0185]    In the operation  418 , the eNB returns a response message corresponding to the IP packet to the SGW over the activated bearer with the specific QoS. 
         [0186]    In the operation  415  to the operation  418 , the UE and the SGW transmit and receive the IP packet over the activated bearer with the specific QoS. 
         [0187]    In the operation  419 , all of the UE, the eNB, and the SGW start a timer (Timeout of Fast Path) each time the IP packet is transmitted, where the bearer is active before the timer expires, and if the timer expires, then the corresponding bearer will be deactivated. The eNB can transmit an RRC Connection Release message to the UE to release the RRC connection of the UE. 
         [0188]    If a PDN connection is set up in advance between the UE and the core network side, then a correspondence relationship between the bearer and the QoS can be created using a Connection ID and the QoS identifier; and the QoS identifier can also be sent in the RRC Connection Setup Request message, and the DRB configuration for the UE can be transmitted in the RRC Connection Setup message. Other parameters than the QoS can also be configured similarly, so a repeated description thereof will be omitted here. 
         [0189]    In a third example, since there may be a plurality of bearers of the core network which are set up in advance for the UE, the UE may initiate transmission of an MO IP packet for a new bearer of the core network which is set up in advance, after the UE creates the correspondence relationship between some bearer of the core network, and the DRB in the first or second example. In this case, the UE may create a correspondence relationship between a new DRB, and the bearer of the core network which is set up in advance, to transmit an IP packet. A flow thereof will be described as follows. 
         [0190]    An initial configuration need to be made prior to an MT process according to the embodiment of the invention: 
         [0191]    1. The eNB obtains through the OAM device a QoS configuration for transmission of an IP packet; or 
         [0192]    2. When allocating a resource identifier to the UE, the MME transmits a QoS identifier (i.e., a resource parameter configuration identifier) and a QoS configuration corresponding to the resource identifier to the eNB; and when allocating the resource identifier to the UE side, the eNB notifies the UE of the QoS identifier and the QoS configuration corresponding to the resource identifier. 
         [0193]    Referring to  FIG. 5 , a parallel MO activating bearer process includes the following operations: 
         [0194]    In the operation  501 , after the UE has set up a DRB for some resource identifier, if the UE has a request to transmit an IP packet for another resource identifier, then the UE can transmit the resource identifier and a QoS indicator to the eNB in a new Bearer Setup Request message. 
         [0195]    In the operation  502 , the eNB determines the SGW to which the IP packet is transmitted by the UE, according to the resource identifier of the core network side of the UE, configures a specific DRB with the QoS configuration corresponding to the QoS identifier, creates a correspondence relationship between the DRB and the bearer of the core network side, and transmits an RRC Connection Reconfiguration message including the resource identifier and a DRB identifier to the UE. 
         [0196]    The DRB identifier here identifies the bearer of the access network, and the resource identifier identifies the bearer of the core network. 
         [0197]    The eNB can create a correspondence relationship between the resource identifier and the DRB so that the UE transmitting the uplink data can simply transmit the data over the corresponding DRB without transmitting the resource identifier (which is only used for addressing by the eNB to locate the corresponding SGW) each time the UE transmits data, thus the eNB can know that the data received over the DRB shall be forwarded to the corresponding SGW. 
         [0198]    In the operation  503 , the UE transmits an RRC Connection Reconfiguration Complete message to the eNB. 
         [0199]    In the operation  504 , the UE transmits the IP packet to the eNB over the activated bearer with the specific QoS. 
         [0200]    In the operation  505 , the eNB transmits the IP packet to the SGW over the activated bearer with the specific QoS. 
         [0201]    In the operation  506 , the SGW returns a response message corresponding to the IP packet to the eNB over the activated bearer with the specific QoS, 
         [0202]    In the operation  507 , the eNB returns the response message corresponding to the IP packet to the UE over the activated bearer with the specific QoS. 
         [0203]    In the operation  503  to the operation  507 , the UE sets up the DRB, and the eNB schedules transmission of the specific IP packet of the UE over the DRB according to the corresponding QoS configuration. 
         [0204]    In the operation  508 , all of the UE, the eNB, and the SGW start a timer (Timeout of Fast Path) each time the IP packet is transmitted, where the bearer is active before the timer expires, and if the timer expires, then the corresponding bearer will be deactivated. The eNB can transmit an RRC Connection Release message to the UE to release the RRC connection of the UE. 
         [0205]    If a PDN connection is set up in advance between the UE and the core network side, then a correspondence relationship between the bearer and the QoS can be created using a Connection ID and the QoS identifier. The QoS identifier can alternatively be reported to the network in existing RRC signaling, e.g., User Equipment (UE) Assistance Information. Other parameters than the QoS can also be configured similarly, so a repeated description thereof will be omitted here. 
         [0206]    In a fourth example, since there may be a plurality of bearers of the core network which are set up in advance for the UE, the UE may initiate transmission of an MT IP packet for a new bearer of the core network which is set up in advance, after the UE creates the correspondence relationship between some bearer of the core network, and the DRB in the first or second example. In this case, the UE may create a correspondence relationship between a new DRB, and the bearer of the core network which is set up in advance, to transmit an IP packet. A flow thereof will be described as follows. 
         [0207]    An initial configuration need to be made prior to an MT process according to the embodiment of the invention: 
         [0208]    1. The eNB obtains through the OAM device a QoS configuration for transmission of an IP packet; or 
         [0209]    2. When allocating a resource identifier to the UE, the MME transmits a QoS identifier (i.e., a resource parameter configuration identifier) and a QoS configuration corresponding to the resource identifier to the eNB; and when allocating the resource identifier to the UE side, the eNB notifies the UE of the QoS identifier and the QoS configuration corresponding to the resource identifier, The MME and the SGW obtain and store the QoS identifier and the QoS configuration corresponding to the resource identifier when allocating the resource identifier for the UE. 
         [0210]    Referring to a parallel MT activating bearer process includes the following operations: 
         [0211]    In the operation  601 , the SGW receives a downlink IP packet for the UE, from the PGW 
         [0212]    in the operation  602 , the SGW transmits a Downlink Data Indicator (DDN) message including a resource identifier of a bearer to the MME for the MME to call the UE. 
         [0213]    In the operation  603 , the MME transmits a paging message including the resource identifier of the bearer to the eNB. 
         [0214]    In the operation  604 , the eNB determines the SGW to which the IP packet is transmitted by the UE, according to the resource identifier of the core network side of the UE, configures a specific DRB with a QoS configuration corresponding to the QoS identifier, creates a correspondence relationship between the DRB and the bearer of the core network side, and transmits an RRC Connection Reconfiguration message including the resource identifier and a DRB identifier to the UE. 
         [0215]    In the operation  605 , the UE transmits an RRC Connection Reconfiguration Complete message to the eNB. 
         [0216]    In the operation  606 , the UE transmits a dummy IP packet to the eNB. 
         [0217]    In the operation  607 , the eNB transmits a dummy IP packet to the SOW to activate transmission of the downlink IP packet. 
         [0218]    Here a dummy IP packet can alternatively be transmitted directly by the eNB instead of the UE to the SGW. 
         [0219]    In the operation  608 , the SGW activates the bearer, and transmits a Downlink Data Indicator (DDN) Complete message to the MME, upon reception of the dummy IP packet. 
         [0220]    In the operation  609 , the SGW transmits the IP packet to the eNB over the activated bearer with the specific QoS. 
         [0221]    In the operation  610 , the eNB transmits the IP packet to the UE over the activated bearer with the specific QoS. 
         [0222]    In the operation  611 , the UE returns a response message corresponding to the IP packet to the eNB over the activated bearer with the specific QoS, 
         [0223]    In the operation  612 , the eNB returns a response message corresponding to the IP packet to the SGW over the activated bearer with the specific QoS. 
         [0224]    In the operation  609  to the operation  612 , the UE and the SOW transmit and receive the IP packet over the activated bearer with the specific QoS. 
         [0225]    In the operation  613 , all of the UE, the eNB, and the SOW start a timer (Timeout of Fast Path) each time the IP packet is transmitted, where the bearer is active before the timer expires, and if the timer expires, then the corresponding bearer will be deactivated. The eNB can transmit an RRC Connection Release message to the UE to release the RRC connection of the UE. 
         [0226]    If a PDN connection is set up in advance between the UE and the core network side, then the UE and the eNB may create a correspondence between the DRB and the PDN connection, and the corresponding QoS configuration. Other parameters than the QoS can also be configured similarly, so a repeated description thereof will be omitted here. 
         [0227]    In a fifth example, An initial configuration need to be made prior to an MO process in a UMTS system according to the embodiment of the invention: 
         [0228]    1. The eNB obtains through the OAM device a QoS configuration for transmission of an IP packet; or 
         [0229]    2. When allocating a resource identifier to the UE, the MME transmits a QoS identifier (i.e., a resource parameter configuration identifier) and a QoS configuration corresponding to the resource identifier to the eNB; and when allocating the resource identifier to the UE side, the eNB notifies the UE of the QoS identifier and the QoS configuration corresponding to the resource identifier. 
         [0230]    Referring to  FIG. 3 , an MO activating bearer process includes the following operations: 
         [0231]    In the operation  701 , the UE transmits an RRC Connection Request message to the eNB. 
         [0232]    In the operation  702 , the eNB returns an RRC Connection Setup message to the UE. 
         [0233]    In the operation  703 , after an RRC connection is set up, the UE transmits a Connection Setup Complete message to the eNB by transmitting a resource identifier of the core network side of the UE and a QoS identifier (the QoS identifier here is a resource parameter configuration identifier) to the eNB in the Connection Setup Complete message, according to a bearer of the core network side for the uplink IP packet to be transmitted by the UE. 
         [0234]    In the operation  704 , the eNB determines the SGW to which the IP packet is transmitted by the UE, according to the resource identifier of the core network side of the UE, configures a specific DRB with a QoS configuration corresponding to the QoS identifier, creates a correspondence relationship between the DRB and the bearer of the core network side, and transmits an RRC Connection Reconfiguration message including the resource identifier and a DRB identifier to the UE. 
         [0235]    In the operation  705 , the UE transmits an RRC Connection Reconfiguration Complete message to the eNB. 
         [0236]    In the operation  706 , the UE transmits the IP packet to the eNB over the activated bearer with the specific QoS. 
         [0237]    In the operation  707 , the eNB transmits the IP packet to a Serving GPRS Support Node (SGSN) and/or a Gateway GPRS Support Node (GGSN) over the activated bearer with the specific QoS.

The eNB can transmit an RRC Connection Release message to the UE to release the RRC connection of the UE. 
         [0241]    If a PDN connection is set up in advance between the UE and the core network side, then a correspondence relationship between the bearer and the QoS can be created using a Connection ID and the QoS identifier; and the QoS identifier can also be sent in the RRC Connection Setup Request message, and the DRB configuration for the UE can be transmitted in the RRC Connection Setup message. Other parameters than the QoS can also be configured similarly, so a repeated description thereof will be omitted here.
