Embodiment
Below in conjunction with drawings and Examples, EPS carrying service control method provided by the invention and MME are illustrated in greater detail.
In the machine communication research project of 3GPP, propose the most important feature of machine communication: machine terminal substantial amounts.For this reason, mobile communication system needs to carry out necessary optimization for this feature, particularly will save the resource of network node.The aspect such as resource that Internet resources comprise air interface resource, network transmission resource, network node use.
Embodiments providing a kind of realization does not provide EPS to carry the method for service, as shown in Figure 1, comprising:
Step 101, Mobility Management Entity MME receives relevant to user terminal UE;
Step 101, MME determine whether to exist in described message be used to indicate not for UE provide Evolved Packet System EPS carry service indication information;
Step 102, when determining to there is described indication information, MME is not for described UE provides EPS to carry service.
EPS sets up the connection of UE to PDN network mainly through ESM (EPS Session Management, EPS session management) process, for UE provides EPS to carry service;
ESM process mainly comprises following process:
The activation of EPS bearer context, deexcitation and amendment;
UE asks the process of EPS bearing resource (IP being included in PDN connects and dedicated bearer resource, dedicated bearer resource).
Each EPS bearer context represents the EPS carrying between UE to a PDN network, even if discharged in the wireless and S1 carrying that corresponding EPS carrying is corresponding temporarily, EPS bearer context also can keep state of activation.
An EPS bearer context can be acquiescence (default) bearer context, also can be a dedicated bearing context.
When UE asks to set up the connection of a PDN in network attachment process, default bearing is activated.
In general, ESM process could perform after only establishing EMM context between UE and MME.First default EPS bearing context activates in EPS attaching process.Once after UE successfully adheres to, UE can ask MME to be established to the connection of other PDN, connects for each PDN, and MME will activate an independent default EPS bearing context.In the whole life cycle that PDN connects, default EPS bearing context is all activate.
A proprietary EPS bearer context always connects with a default EPS bearing context dependent, and represents the EPS bearing resource between UE and PDN network except default bearing.Network can activate special EPS bearer context while activation default EPS bearing, or any time after EPS default bearing activates activates dedicated bearer.
Acquiescence and special EPS bearer context can be modified.Special EPS bearer context can be released and not affect default EPS bearing context.When default EPS bearing context is released, so all dedicated bearings be associated with it are all released.
UE can ask network allocation, amendment and release EPS bearing resource.Network decides how to meet the request for extra resource: or an almost new EPS carrying, or revise existing special or default EPS bearing context.
Therefore ESM process mainly contains 2 large classes:
The same EPS bearer context of 1, being initiated by network manages relevant ESM process, mainly comprises:
Default EPS bearing context activation;
Special EPS bearer context activates;
EPS bearer context is revised;
The deexcitation of EPS bearer context;
The process that the same EPS bearing resource of 2, being initiated by UE is relevant, as a new PDN connects or dedicated bearer resource; Or discharge these resources, mainly comprise following process:
PDN connection procedure;
PDN removes connection procedure;
Bearing resource assigning process;
Bearing resource revised title.
The EPS that the embodiment of the present invention provides carries service control method, MME by receive the message relevant to UE determine whether there is instruction not for UE provide without EPS carry serve indication information time, not for UE provides EPS to carry service, thus save and provide EPS to carry to serve the various resource that uses and the demand that can meet UE.The above-mentioned message relevant to UE can network side node send, also can be user side equipment send, above-mentioned instruction not for UE provide without EPS carrying serve indication information, can be various message form.
Preferably, described MME is MME accompanying in network attachment process, like this, in network attachment process, MME is not for above-mentioned UE provides EPS to carry service, described indication information is specially instruction UE and does not support that EPS carries the UE core net ability information of service, or is that carrying without EPS in subscription data serves instruction.
For the UE (UE may support that EPS carries service and also may not support) not needing EPS to carry service, increase in subscription data and carry service instruction No EPS Bearer ServiceIndicator without Evolved Packet System EPS, MME does not provide EPS to carry service to this type of UE according to this instruction in network attachment process, namely can not perform above-mentioned ESM process; Or, by the instruction UE that UE reports, MME does not support that EPS carries the UE core competence information of service, can determine that this UE does not support that EPS carries service, for not supporting that EPS carries the UE of service, MME not to this type of UE provide EPS carry service, also just save need in above-mentioned ESM process air interface resource, network transmission resource, network node use storage resources etc., especially the inventive method is applied to MTC terminal, can resources in network greatly, reduce network overhead.
As previously mentioned, in prior art, in the network attachment process of UE, MME can send reconstruction default bearer request message and connect to ask network to set up first PDN.The embodiment of the present invention is in network attachment process, and MME does not provide EPS to carry service for described UE, specifically comprises: MME does not connect for described UE sets up grouped data network PDN.Particularly, be in network attachment process, described MME is not that described UE activates default bearing.In the unactivated situation of default bearing, would not set up default bearing context, the PDN that can not set up other connects, and amendment and the PDN that also can not relate to carrying go the ESM processes such as connection, therefore greatly save Internet resources.
Preferably, MME is not that described UE activates default bearing, and specifically comprise: in network attachment process, described MME does not perform: select gateway node for described UE and send to the gateway node selected to create default bearer request message.
Because HSS to carry the subscription data of UE to the renewal position acknowledge message that MME sends, preferably, MME, specifically from the renewal position acknowledge message that home subscriber servers HSS sends, obtains and indicates without EPS carrying service; In some cases, UE can carry UE core net ability information in attachment message, preferably, the attachment message that the embodiment of the present invention can also report from UE, obtains instruction UE and does not support that EPS carries the UE core net ability information of service.
Having the UE of No EPS Bearer Service Indicator in subscription data and do not support that EPS carries the UE of service, is the MTC device not needing EPS to carry service, certainly, can also be that other type does not need EPS to carry the terminal type of service.
MME does not connect for UE sets up PDN in network attachment process, thus can save following operation: not for UE contracts any APN APN; Not for UE provides support the service needed for connected state mobility; Not for the provide support PDN of LIPA (Local IP Access, local IP access) of UE connects; Not for UE sets up ESM context; Not for UE performs ESM management process.
