Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of transmission of device capability information and acquisition methods, device.
Background technology
At subscriber equipment (User Equipment, UE) flow process, tracing section updating (Tracking Area Update are asked in adhering to of initiating, TAU) in flow process, the switching flow, all may relate to gateway (Serving Gate Way, SGW) change, need Mobility Management Entity (Mobility ManagementEntity, MME) to finish the selection function of SGW according to tracking area identification (Tracking Area Identity, TAI).
When UE switched, source MME after determining to stride the switching of MME network element, need to select a suitable MME as purpose MME network element from one group of purpose MME according to target BS sign (Target eNodeB ID) according to TAI.
These have all related to the problem of selecting a suitable network element from the one group of purpose network element in opposite end.Select network element need to know the ability information of opposite end.
In the prior art, MME selects SGW according to the load sharing principle, and namely the SGW address list that returns according to name server (Domain Name Server, DNS) of network element carries out poll and preferred.If the SGW network element of static configuration, need the disposal ability of static configuration SGW.If change has occured in SGW network element ability in the meantime, but can not in time notify the MME network element, the selection SGW of MME load sharing is greatly affected.
When UE switches, source MME after determining to stride the switching of MME network element, chooses one group purpose MME according to TAI according to Target eNodeB ID, source MME therefrom selects a MME as purpose MME according to the load sharing principle, equally also needs to know the disposal ability information of each MME network element.
In the prior art, can be on certain network element node static configuration opposite end network element ability, if opposite end network element ability is revised, can not in time must get access to, and must the manual operation configuration.Can also be the ability information of other network elements of the upper configuration of DNS in addition, network element also be to dispose other network element abilities in dns server left-hand seat sound attitude by obtaining alternately the network capabilities of other network elements with dns server at present.
In sum, the scheme shortcoming of prior art is the information on load that needs operator's manual configuration SGW network element and adjacent MME network element, rather than the information on load of other network elements of Dynamic Acquisition, such shortcoming is if the load of certain network element is very high, and need the network element of with it communication in unwitting situation, to tend to alternately with it failure, the time that has so just postponed user access network, affected user's experience.
