Implement the mode of the present invention
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, it is right The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and It is not used in the restriction present invention.
The specific embodiment of the invention provides a kind of method of the PS access capabilities of acquisition UE, and this method is complete by the network equipment Into the network equipment is specifically as follows：Mobile switching centre（Mobile Switching Center, MSC）, BSC, service branch Serve as a diplomatic envoy a little（Serving GPRS SUPPORT NODE GPRS, SGSN）Or mobility management entity（Mobility Management Entity, MME）；This method as shown in Figure 1, including：
S11, when carrying out rSRVCC switchings, the network equipment obtain UE PS access capabilities；
PS access capabilities are sent to the target BS of rSRVCC switchings by S12, the network equipment.
When carrying out rSRVCC switchings, the PS that UE is obtained by the network equipment connects the method that the specific embodiment of the invention provides Enter ability, and PS access capabilities are sent to the target BS of rSRVCC switchings, so that target BS can know UE's PS access capabilities, so that target BS can be preferably the UE allocation schedule resources according to the PS access capabilities of UE.
Optionally, above-mentioned target BS is specifically as follows：RNC or eNB.
Optionally, the concrete implementation method of above-mentioned S11 can be any one of following manner：When the network equipment is During BSC, its implementation can be such as any one in following manner A, mode B or mode E, when the network equipment is target SGSN Or during target MME, its implementation can be such as following manner C；When the network equipment is MSC, its implementation can be as following Mode D
Mode A, when carrying out rSRVCC switchings, receive the PS access capabilities that report of UE.
Wherein, the concrete methods of realizing for the PS access capabilities that UE is reported can be：In Classmark change message（CLASSMARK CHANGE message）In increase IE newly, which carries PS access capabilities, can also increase a piece of news newly certainly PS access capabilities are carried, which is specifically as follows：PS classmark change message, actually should certainly In, or the newly-increased message of others.
Mode B, send the instruction message for reporting PS access capabilities to UE, receives UE and is connect according to the PS that the instruction message returns Enter ability.
Wherein, above-mentioned instruction message is specifically as follows：CLASSMARK ENQUIRY（Category is inquired about）Message；Wherein The newly-increased instruction of CLASSMARK ENQUIRY can be PS RAC MASK, and above-mentioned newly-increased instruction is used to indicate that UE reports PS to access Ability, certain above-mentioned newly-increased instruction can also use other modes.The PS access capabilities of above-mentioned return can be carried to return in UE Multiple new information（PS CLASSMARKCHANGE）It is interior, certainly in a practical situation, can also be in Classmark change Increased newly in message in IE and carry PS access capabilities or PS access capabilities are carried in other message, it is certainly above-mentioned newly to disappear Breath can also have other forms of expression, and the embodiment of the present invention is not intended to limit the form of expression of above-mentioned new information.
Mode C, when carrying out rSRVCC switchings, the network equipment to source SGSN obtain UE PS access capabilities, be segmented into Two ways.
First way can be：When target SGSN or target MME obtains the PS contexts of the UE to source SGSN, connect That receives the source SGSN transmissions carries the PS context response informations of the PS access capabilities, for example, can pass through context response（Context response）Increase MS radio access capability cell in message（mobile station radio Access capability IE, MS RAC IE）Carry PS access capabilities, naturally it is also possible to report by other message The PS access capabilities of UE.Wherein, the PS access capabilities of the UE are that UE is occurring to adhere to attach or Routing Area Update Routing Area updating, RAU）When, PS access capabilities are sent to source SGSN.
Can be for second：The request message of the PS access capabilities of the UE is reported to source SGSN transmissions instruction source SGSN, The response message for the PS access capabilities carried that reception source SGSN is returned；Wherein, the response message of PS access capabilities is carried Can be：Increase the context response message of MS RAC IE；Above-mentioned instruction source SGSN reports the request of PS access capabilities Message is specifically as follows：Increase the context request message of MS RACrequired indication IE, the MS RAC required indication IE represent target（target）MME/SGSN is to source（source）SGSN asks for PS accesses Ability.Certainly, above-mentioned request message and response message can also be substituted with other message in practical applications, the present invention Embodiment is not intended to limit the specific manifestation form of above-mentioned request message or response message.
Mode D, when carrying out rSRVCC switchings, the network equipment receives the Non-Access Stratums that report of UE（Non-access Stratum, NAS）Message, the NAS message carry PS access capabilities.It should be noted that above-mentioned UE report carry PS The NAS message of access capability has two kinds of implementations, the first, UE active reporting NAS messages；Second, network side equipment to After UE sends the instruction message for reporting PS access capabilities, UE returns to the NAS message for carrying PS access capabilities.
Mode E, when carrying out rSRVCC switchings, the network equipment receives the NAS for carrying PS access capabilities that report of UE and disappears Breath, parsing NAS message obtain PS access capabilities.
