It is presented a method for error handling during a Mobile Terminated, MT, call to a User Equipment, UE, in a cellular system. The method is performed by a network device being an alternative Mobility Management Entity, MME, of the cellular system. The method comprises the steps of: failing to forward a paging request to a serving MME, at which the UE is registered; and paging the UE using a Circuit Switched, CS, paging. A corresponding network device, User Equipment, computer program and computer program product are also presented. 1. A method for error handling during a Mobile Terminated , MT , call or SMS to a User Equipment , UE , in a cellular system , the method being performed by a network device being an alternative Mobility Management Entity , MME , of the cellular system and comprising the steps of:failing to forward a paging request to a serving MME, at which the UE is registered; andpaging the UE using a Core Network, CN, domain equal Circuit Switched, CS, paging.2. The method according to claim 1 , wherein said step of paging comprises paging the UE using a System Architecture Evolution—Temporary Mobile Subscriber Identity claim 1 , S-TMSI claim 1 , and limit the paging scope by use of a Tracking Area Identity claim 1 , TAI claim 1 , list from a UE Context Replica.3. The method according to claim 1 , wherein said step of paging comprises paging the UE using an International Mobile Subscriber Identity claim 1 , IMSI claim 1 , based CN domain equal CS paging to Evolved Node Bs claim 1 , eNodeBs claim 1 , of Tracking Areas claim 1 , TAs claim 1 , list which is configured to match a Location Area claim 1 , LA claim 1 , wherein a Mobile Switching Centre claim 1 , MSC/VLR claim 1 , has the UE registered.4. The method according to claim 1 , wherein said step of paging comprises paging the UE using an IMSI based CN domain equal CS paging to a combined service area of the MME and the MSC/VLR.5. The method according to claim 1 , further comprising the steps of ...
