Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of transmission and side of obtaining of device capability informationMethod, device.
Background technology
Flow process, tracing section updating are asked in adhering to of initiating at subscriber equipment (UserEquipment, UE)In (TrackingAreaUpdate, TAU) flow process, switching flow, all may relate to gateway(ServingGateWay, SGW) changes, and needs Mobility Management Entity (MobilityManagementEntity, MME) complete the choosing of SGW according to tracking area identification (TrackingAreaIdentity, TAI)Select function.
In the time that UE switches, source MME is according to target BS mark (TargeteNodeBID), reallySurely after being the switching across MME network element, need to from one group of object MME, select according to TAI one suitableMME as object MME network element.
These have all related to the problem of selecting a suitable network element from the object network element of one group of opposite end. Select netThe ability information of opposite end need to be known by unit.
In prior art, MME selects SGW according to load sharing principle, and network element is according to name serverThe SGW address list that (DomainNameServer, DNS) returns carries out poll and preferred. IfBe the SGW network element of static configuration, need the disposal ability of static configuration SGW. If SGW in the meantimeHaving there is change in network element ability, but can not notify in time MME network element, makes the choosing of MME load sharingSelecting SGW is greatly affected.
In the time that UE switches, source MME, according to TargeteNodeBID, determines it is across MME network elementSwitching after, choose one group of object MME according to TAI, source MME according to load sharing principle therefromSelect a MME as object MME, equally also need to know the disposal ability letter of each MME network elementBreath.
In prior art, can be on certain network element node static configuration opposite end network element ability, if opposite end netUnit's ability amendment, can not must get in time, and must manual operation configuration. Can also be DNS in additionThe ability information of upper other network elements of configuration, network element is by obtaining alternately the net of other network elements with dns serverNetwork ability is also in moving other network element abilities of static configuration of dns server left-hand seat at present.
In sum, the scheme shortcoming of prior art is to need operator's manual configuration SGW network element and neighbourThe information on load of MME network element, instead of the information on load of other network elements of Dynamic Acquisition, such shortcoming isIf the load of certain network element is very high, and the network element that need to communicate by letter is with it mutual with it in unwitting situationTend to failure, so just postponed the time of user access network, affected user's experience.
