It is EPC (Evolved Packet Core that EPS carries; The packet-based core networks of evolution)/E-UTRAN (Evolved Universal Terrestrial Radio Access Network; The universal land radio access web of evolution) carries out QoS (Quality of Service; Service quality) granularity of control is taked same bearer level packet forward strategy to the flow that is mapped to same EPS carrying; An EPS carries network element and the interface that needs through different, and on each interface, is mapped to different bottoms carryings; Each network node is responsible for safeguarding the sign of bottom carrying and binding relationship each other; Comprise that eNodeB (being the base station) through creating the binding between radio bearer and the S1 carrying, realizes the mapping between radio bearer and the S1 carrying; S-GW (Serving Gateway, gateway) passes through to create the binding between S1 carrying and the S5/S8 carrying, the mapping between realization S1 carrying and S5/S8 carry; Final EPS carries the cascade that data are carried through radio bearer, S1 carrying and S5/S8; Realize UE (User Equipment; Subscriber equipment) with between the PDN (Packet Data Network, packet data network) connect professional support, to guarantee required qos requirement.
As shown in Figure 1, in the bearing activation process, when UE initiates service request; According to generating relevant strategy and charge information, send to PCRF (Policy and Charging Rules Function, strategy and charging rule functions) with user interactions; Issue corresponding charging regulation and qos policy by PCRF and give PDN-GW (Packet Data Network Gateway; Grouped data network gateway) PCEF in (Policy and Charging Enforcement Function, strategy and charge execution function), PCEF are that EPS Bearer (carrying) qos parameter is (like QCI (QoS Class Identifier according to qos policy; The qos class sign); ARP (Address Resolution Protocol, address resolution protocol), GBR (Guaranteed Bit Rate; Guarantee bit rate) and MBR (maximum bit rate, maximum bit rate) etc.) apportioning cost.
If there is not configuring static PCC (Policy and Charging Control, policy and charging control) rule, PDN-GW uses inner qos policy to distribute EPS Bearer qos parameter value; If carrying, do not set up corresponding EPS; PDN-GW sends to eNodeB with EPS Bearer qos parameter through S-GW, MME (Mobility Management Entity, Mobility Management Entity) through Create (foundation) Dedicated (special use) Bearer (carrying) Request (request) message (message); ENodeB is mapped as Radio (wireless) Bearer QoS with EPS Bearer qos parameter; Think in conjunction with the current wireless situation and can set up radio bearer; And Radio Bearer QoS is sent to UE through RRC (Radio Resource Control, Radio Resource control) Connection (connection) Reconfiguration (reshuffling) message; UE is through sending the foundation of RRC Connection Reconfiguration Complete (completion) message to eNodeB affirmation Radio Bearer; UE provides EPS Bearer QoS parameters (parameter) so that application layer handles service data flow (business data flow) to application layer (application layer).
Each EPS carries and a TFT (Traffic Flow Template in addition; Traffic flow template) relevant, DL (descending) TFT that TFT divides for UL (up) TFT that is made up of one group of ul packet filter and is made up of one group of downlink packets filter; As PGW (Packet Data Gateway, packet data gateway) when receiving downlink packets, PGW is routed to downlink packets in the different EPS carryings according to the downlink packets filter of distributing among the TFTs that EPS that PDN connects carries.
It should be noted that; PGW is according to the size ordering of the priority of each downlink packets filter; And begin from the minimum packet filter of priority; Check whether downlink packets and this packet filter that it receives mate, if coupling then send to dividing into groups with EPS through the tunnel and to carry relevant S-GW; If do not match then continue relatively to divide into groups and the higher packet filter of next priority; If P-GW does not relatively find occurrence after all packet filters, then P-GW sends to this grouping in the EPS carrying that is not assigned with any downlink packets filter, if do not exist this type EPS to carry, then P-GW abandons this grouping; The IP packet is mapped to different EPS through TFT and carries, and ensures thereby obtain corresponding QoS.
Two, local IP access network framework.
As shown in Figure 2, in order to reduce the network side cost and to avoid network side congested, a kind of network side implementation is that IP network is directly inserted in base station (or passing through IP gateway), and the base station is AP (Access Point, an access point) in this framework; Different with traditional IP is, carry out through eating dishes without rice or wine to the transmission of UE the base station, and the base station sends to UE through eating dishes without rice or wine with the IP packet, and need on eating dishes without rice or wine, guarantee the desired QoS of IP packet.

Embodiment one
The embodiment of the invention one provides a kind of transmission method of IP packet; AP equipment (or passing through IP gateway) directly is connected with IP network (network side) through the IP interface; And the transmission (be that AP equipment sends to UE through eating dishes without rice or wine with the IP packet, and UE sending to AP equipment through eating dishes without rice or wine with the IP packet) through the IP packet of eating dishes without rice or wine to carry out with UE; In order to set up the needed DRB of IP packet (being empty port load-supporting), and guarantee that the IP packet can correctly be carried on the corresponding DRB, realize its QoS that needs transmission; Then to the handling process of AP equipment side, shown in Fig. 3 A, this method may further comprise the steps:
Step 301A, the acquisition of AP equipment need send to the IP packet of UE, and carries the QoS demand information in this IP packet; Wherein, AP equipment can receive the IP packet that need send to UE from IP network, and this QoS demand information can be the IP priority of data packets.
Step 302A, AP equipment judge currently whether have DRB can satisfy the QoS demand information; If, execution in step 303A; If not, execution in step 304A.
Step 303A, AP equipment sends to UE through the DRB that satisfies the QoS demand information with the IP packet.Concrete, based on the current DRB that has set up, AP equipment can directly utilize the DRB that satisfies the QoS demand information that the IP packet is sent to UE.
Step 304A, AP equipment sends to UE through the minimum DRB of priority with the IP packet.Concrete, based on the current DRB that has set up, AP equipment can directly utilize the minimum DRB of priority that the IP packet is sent to UE.
It should be noted that flow process shown in above-mentioned Fig. 3 A for to the handling process of AP equipment side, and in order to set up the needed DRB of IP packet, and guarantee that the IP packet can correctly be carried on the corresponding DRB; Then to the handling process of UE side, shown in Fig. 3 B, this method can also may further comprise the steps:
Step 301B, the UE acquisition need send to the IP packet of AP equipment, and carries the QoS demand information in this IP packet; Wherein, when AP equipment sends the IP packet, can obtain to send to the IP packet of AP equipment, and this QoS demand information can be the IP priority of data packets at UE.
Step 302B, UE judge currently whether have DRB can satisfy the QoS demand information; If, execution in step 303 B; If not, execution in step 304 B.
Step 303B, UE sends to AP equipment through the DRB that satisfies the QoS demand information with the IP packet.Concrete, based on the current DRB that has set up, UE can directly utilize the DRB that satisfies the QoS demand information that the IP packet is sent to AP equipment.
Step 304B, UE sends to AP equipment through the minimum DRB of priority with the IP packet.Concrete, based on the current DRB that has set up, UE can directly utilize the minimum DRB of priority that the IP packet is sent to AP equipment.
It should be noted that in order to realize said process, need carry out the process of setting up of Data Radio Bearer DRB, and the mode of setting up Data Radio Bearer DRB comprises:
Mode one, static state are set up the mode of DRB.
In the embodiment of the invention, AP equipment is set up the DRB of all permissions according to information (DRB that wherein includes all corresponding permissions of UE) such as contracting of UE for this UE when initially setting up DRB; If current interface-free resources allows for the DRB that UE sets up all permissions, then AP equipment is the DRB that UE sets up all permissions; If current interface-free resources does not allow for the DRB that UE sets up all permissions; Then AP equipment refusal is set up DRB (promptly all DRB set up failure) or is set up the part DRB that interface-free resources allows (promptly set up part DRB, but follow-up can not set up new DRB again) for UE for UE.
Under this mode, after setting up DRB, if the acquisition of AP equipment need send to the IP packet of UE, then when DRB can satisfy the QoS demand of IP packet, the DRB of the QoS demand through can satisfying the IP packet sends to UE with the IP packet; When not having DRB can satisfy the QoS demand of IP packet among the DRB of all foundation, the DRB minimum through priority sends to UE with the IP packet; In like manner, if the UE acquisition need send to the IP packet of AP equipment, then when DRB can satisfy the QoS demand of IP packet, the DRB of the QoS demand through can satisfying the IP packet sends to AP equipment with the IP packet; When not having DRB can satisfy the QoS demand of IP packet among the DRB of all foundation, the DRB minimum through priority sends to AP equipment with the IP packet.
Mode two, dynamically set up the mode of DRB, it can dynamically set up DRB according to modes such as UE request or AP equipment initiatively trigger.
In the embodiment of the invention, need send to the IP packet of UE when the acquisition of AP equipment after, if the current DRB that has set up does not all satisfy the desired QoS demand of this IP packet, then trigger DRB and dynamically set up process; Perhaps; Need send to the IP packet of AP equipment when the UE acquisition after; If the current DRB that has set up does not all satisfy the desired QoS demand of this IP packet, then ask AP equipment for this UE sets up the corresponding DRB of this QoS demand, trigger AP equipment execution DRB and dynamically set up process.
Concrete, AP equipment need be according to information such as the CAMEL-Subscription-Information of UE, current interface-free resources in the process of dynamically setting up DRB, judges whether that enough interface-free resources set up this DRB to UE; If have, then DRB sets up successfully, and AP equipment will increase the corresponding configuration notification of DRB newly through the RRC reallocation message and give UE; If no, then DRB sets up unsuccessful.Further, unsuccessful if DRB sets up, then AP equipment need be provided with a timer for this QoS demand, if receive the IP packet that sends to the identical QoS demand of having of this UE once more, and timer is not overtime, does not then initiate DRB and dynamically sets up process; If it is the UE request trigger that DRB dynamically sets up process; Then AP equipment also need return a failed message (wherein possibly comprise timer) to UE; If UE obtains to have the IP packet of identical QoS demand once more, and timer is not overtime, does not then ask DRB dynamically to set up process.
Under this mode, if the acquisition of AP equipment need send to the IP packet of UE, when between AP equipment and UE, having set up the DRB of the QoS demand that can satisfy the IP packet, then the DRB of the QoS demand through can satisfying the IP packet sends to UE with the IP packet; When between AP equipment and UE, not setting up the DRB of the QoS demand that can satisfy the IP packet, then the IP packet is sent to UE through the minimum DRB of priority; In like manner, if the UE acquisition need send to the IP packet of AP equipment, when between AP equipment and UE, having set up the DRB of the QoS demand that can satisfy the IP packet, then the DRB of the QoS demand through can satisfying the IP packet sends to AP equipment with the IP packet; When between AP equipment and UE, not setting up the DRB of the QoS demand that can satisfy the IP packet, then the IP packet is sent to AP equipment through the minimum DRB of priority.
To aforesaid way one, then AP equipment judges currently whether have DRB can satisfy the QoS demand information to comprise: AP equipment is the DRB that UE sets up all permissions according to the CAMEL-Subscription-Information of UE when initially setting up DRB; Whether judge among the DRB of all permissions has DRB can satisfy the QoS demand information; If confirm that then the current DRB of having can satisfy the QoS demand information; If, do not confirm that then the current DRB of not having can satisfy the QoS demand information.Wherein, AP equipment is that the DRB that UE sets up all permissions comprises according to the CAMEL-Subscription-Information of UE: if current interface-free resources allows for the DRB that UE sets up all permissions, then set up the DRB of all permissions for UE; If current interface-free resources does not allow for the DRB that UE sets up all permissions, then refuse perhaps to set up the part DRB that interface-free resources allows for UE for UE sets up DRB.
UE judges currently whether have DRB can satisfy the QoS demand information to comprise: is after UE sets up the DRB of all permissions at AP equipment according to the CAMEL-Subscription-Information of UE, and whether UE judges among the DRB of all permissions has DRB can satisfy the QoS demand information; If confirm that then the current DRB of having can satisfy the QoS demand information; If, do not confirm that then the current DRB of not having can satisfy the QoS demand information.
To aforesaid way two, then AP equipment judges currently whether have DRB can satisfy the QoS demand information to comprise: whether AP equipment is judged among the current DRB that has existed has DRB can satisfy the QoS demand information; If confirm that then the current DRB of having can satisfy the QoS demand information; Then CAMEL-Subscription-Information and the current interface-free resources according to UE judges whether to allow to set up the DRB that can satisfy the QoS demand information if not; If allow, confirm that then the current DRB of having can satisfy the QoS demand information; If do not allow, confirm that then the current DRB of not having can satisfy the QoS demand information.
Further, if allow to set up the DRB that can satisfy the QoS demand information, then AP equipment is that UE sets up the DRB that can satisfy the QoS demand information; If do not allow to set up the DRB that can satisfy the QoS demand information, then AP equipment is that said QoS demand information is provided with timer, and at the timer run duration, confirms that directly the current DRB of not having can satisfy described QoS demand information.
Further; The DRB that AP equipment can also receive from UE sets up request message (this DRB sets up the QoS demand information of the request of carrying in the request message), the DRB that judges whether to allow to set up the QoS demand information that can satisfy request according to CAMEL-Subscription-Information and the current interface-free resources of UE; If then set up the DRB of the QoS demand information can satisfy request, and the configuration of DRB sent to UE through the RRC reallocation message for UE; If not, then the QoS demand information for request is provided with timer, and at said timer run duration, confirms that directly the current DRB of not having can satisfy the QoS demand information of described request; And return failed message to UE, carry the information of timer in this failed message.
In the embodiment of the invention, UE judges currently whether have DRB can satisfy the QoS demand information to comprise: whether UE judges among the current DRB that has existed has DRB can satisfy the QoS demand information; If confirm that then the current DRB of having can satisfy the QoS demand information; If not, then send DRB and set up request message, and this DRB sets up and carries the QoS demand information in the request message to AP equipment; If receive the configuration of the DRB that AP equipment returns through the RRC reallocation message, confirm that then the current DRB of having can satisfy described QoS demand information; If receive the failed message that AP equipment returns, confirm that then the current DRB of not having can satisfy described QoS demand information.
Further; When carrying the pairing timer of QoS demand information in this failed message; UE does not send to AP equipment and asks the DRB that sets up said QoS demand information to set up request message, and confirm that directly the current DRB of not having can satisfy the QoS demand information at the run duration of timer.
In the embodiment of the invention,, think that then this DRB is in deactivation status, and need to connect the corresponding configuration of reallocation message notice UE this DRB of deletion through RRC if the DRB of AP device discovery foundation does not have the IP data packet transmission specifying in continuous time; Further, when UE receives from the corresponding information configured of the deletion DRB of AP equipment, the corresponding DRB of UE deletion then; Perhaps, when UE detect with AP equipment break off be connected after, delete the DRB of all foundation.
Embodiment two
